Background

The internet protocol sixth version of the segmented routing service function chain (Segment Routing v6 Service Function Chaining, SRv6 SFC) is a service function chain technique based on internet protocol sixth version (Internet Protocol version, IPv 6) segmented routing. The method combines the concepts of SRv and service function chains, can realize flexible and efficient network flow scheduling and service link customization, and is a technology for guiding a message to sequentially pass through application layer service equipment according to a designated path by adding SRv path information in an initial message.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.

It should be noted that, the user information (including but not limited to user equipment information, user personal information, etc.) and the data (including but not limited to data for analysis, stored data, presented data, etc.) referred to in the present application are information and data authorized by the user or fully authorized by each party, and the collection, use and processing of the related data need to comply with the related laws and regulations and standards, and provide corresponding operation entries for the user to select authorization or rejection.

For ease of understanding, the present SFC system architecture based on SRv6 will be described first.

Fig. 1 is a schematic structural diagram of a SRv SFC network provided in the present application. As shown in fig. 1, the networking may include: a Service classification (Service Classifier, SC) node, a Service chaining forwarding (Service Function Forwarder, SFF) node, an application Service (SF) node, a subscriber network node of a Service initiator, a subscriber network node of a Service receiver.

The connection between any two nodes is based on IPv6 network connection.

The SC node is located at the network edge of SRv SFC and is a source node of the functional service chain path, and may adopt different drainage modes to introduce the service data from the user network node of the service initiator into the SRv transmission engineering Policy (Traffic Engineering Policy, TE Policy) tunnel for forwarding.

The SFF node is used as a functional service chain agent of the SF node, the received message is forwarded to a plurality of SF nodes associated with the SFF node according to SRv encapsulation information, the SF node processes the message and returns the message to the SFF node, and the SFF node finally decides whether to continue forwarding the message.

The SF node is a node providing a specific application service for the service flow and is used for processing the service-related message received from the SFF node.

However, the current network architecture is mainly an IPv4 network architecture, and in some scenarios, the network architecture is an IPv 4-only architecture. When the network architecture is an IPv4 architecture, the transmitted message is also an IPv 4-based message, and the relevant setting based on SRv is not provided, so that the SFC based on SRv cannot be used for message transmission and service processing, and the problem of service data transmission limitation is caused.

According to the communication method, the SC node and the SFF node are configured to be nodes supporting the first network protocol and the second network protocol through the dual-stack technology, and the data transmission tunnel between the SC node and the SFF node is configured to be a tunnel supporting network protocol conversion (namely, transmitting data based on the second network protocol in the network of the first network protocol), so that the SC node can transmit and forward the message of the target service based on the first network protocol through the second network protocol, and the problem of limited service data transmission is avoided.

Next, a description will be given of a structure of networking of the communication method provided in the embodiment of the present application.

Fig. 2 is a schematic structural diagram of a communication network according to an embodiment of the present application. As shown in fig. 2, the structure may include: the system comprises a service orchestrator, a service classification node, at least one forwarding node, at least one application server, a terminal node, a user network node of a service initiator and a user network node of a service receiver.

The service classification node and the forwarding node, the forwarding node and other forwarding nodes, and the forwarding node and the destination node are all connected through a tunnel supporting network protocol conversion (namely, data based on a second network protocol is transmitted in a network of a first network protocol), and the tunnel can be an IPv6-over-IPv4 (6 to4 for short) tunnel assuming that the first network protocol is IPv4 and the second network protocol is IPv 6. The connection between the forwarding node and at least one application server corresponding to the forwarding node and between the terminal node and the user network node of the service receiver is a tunnel based on a first network protocol. The service classification node, the at least one forwarding node, and the destination node may be service gateways serving as corresponding nodes.

The service orchestrator determines an orchestration result of a functional service chain corresponding to the service request according to the service request sent by a user network node of a service initiator, namely, determines a network transmission path of the service request, and transmits a message corresponding to the service in sequence through nodes and nodes of the network transmission path. The service orchestrator issues the network transmission path to the service classification node, so that the service classification node can control transmission of the service message.

The service classification node, the forwarding node and the destination node are all nodes supporting the first network protocol and the second network protocol, the function of the service classification node in the function service chain is the same as that of the SC node in the foregoing figure 1, the function of the forwarding node in the function service chain is the same as that of the SFF node in the foregoing figure 1, and the destination node is a node for distributing messages to the user network node of the service receiver. The application server is a server only supporting the first network protocol, and its function in the functional service chain is the same as that of the SF node in fig. 1, which is not described herein.

It should be understood that the first network protocol and the second network protocol in the embodiments of the present application may be any network protocol, for example, the first network protocol may be IPv4, and the second network protocol may be IPv6, and the first network protocol and the second network protocol are not limited in this application, so long as they are two different network protocols. The network protocol conversion protocol is determined according to the first network protocol and the second network protocol, and is used for converting the message of the first network protocol into the message of the second network protocol, for example, the 6to4 protocol. The functional service chain is based on a second network protocol.

Next, a detailed description will be given of the technical solution of the present application and how to solve the above technical problems by using the architecture shown in fig. 2 through a specific embodiment. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

First, an explanation will be given of how the service orchestrator determines orchestration of functional service chains according to the target traffic. Fig. 3 is a flow chart of a communication method according to an embodiment of the present application. As shown in fig. 3, the method may include:

s301, a user network node of a service initiator sends out a service request of a target service.

Accordingly, the service orchestrator receives the service request for the target service.

Wherein the service orchestrator is a service orchestrator corresponding to the user network node of the service initiator. The target service is a network service based on the first network protocol, for example, may be a cloud computing service, a data center service, a video service, an e-commerce service, and the like, which is not limited in this application. The service request is a request sent by a user network node of a service initiator, where the user network node may be, for example, a user server, a user terminal, and the terminal may be, for example, a computer, a mobile phone, a tablet computer, and the like.

S302, the service orchestrator determines a target application server corresponding to the target service according to the type of the service request and the mapping relation between the service type and the application server.

The service type may be determined according to actual requirements, for example, according to the classification of the target service, or according to a more detailed classification under each classification. The application server is used for processing the service corresponding to the application server, and the application servers for processing the target services of different service types are different.

The mapping relationship between the service type and the application server may be pre-stored in the service orchestrator or stored in a database corresponding to the service orchestrator. The service orchestrator can determine a target service corresponding to the service request according to the service request, and determine a service type of the target service according to the target service. And determining a target application server corresponding to the target service through the service type and the mapping relation between the service type and the application server.

S303, the service orchestrator generates configuration information of a functional service chain of the target business based on the second network protocol according to the first service gateway corresponding to the target application server and the second service gateway.

The first service gateway is a forwarding node on a functional service chain, the second service gateway is a service classification node on the functional service chain, and both the first service gateway and the second service gateway support a first network protocol and a second network protocol. The configuration information of the functional service chain comprises forwarding nodes and service classification nodes corresponding to at least one target application server for processing the target service, and transmission paths for transmitting messages of the target service in the forwarding nodes and the service classification nodes. For example, a service identifier (Service Identifier, SID) of each first service gateway as a forwarding node may be included, and the SIDs may be arranged according to a transmission path of a message transmitting the target service, where the SID of the first service gateway through which the message passes first is arranged before and the SID of the first service gateway through which the message passes later is arranged after.

The forwarding node included in the configuration information of the functional service chain may be determined according to the target application servers corresponding to the target service, where each target application server corresponds to a forwarding node in communication connection with the target application server, and the service classification node is a service classification node corresponding to a user network node of the service initiator. The service orchestrator may be connected to a plurality of service classification nodes, and write the SID of the service classification node in the configuration information of the functional service chain according to the service classification node corresponding to the target service.

S304, the service orchestrator issues the function service chain configuration information to the second service gateway.

Correspondingly, the second service gateway receives the functional service chain configuration information of the target business based on the network architecture of the second network protocol, which is sent by the service orchestrator.

The function service chain configuration information is generated by the service orchestrator according to a first service gateway corresponding to a target application server and a second service gateway, wherein the target application server is an application server corresponding to a target service, and the target application server supports a first network protocol. In the network architecture, a network connection between a first service gateway and a second service gateway is a tunnel capable of converting a second network protocol into a first network protocol.

The second service gateway is a second service gateway for subsequently receiving the message of the target service, the second service gateway is related to the target service, and the service orchestrator can determine the second service gateway according to the service type of the target service and write the second service gateway into the functional service chain configuration information.

By transmitting the configuration information of the functional service chain to the second service gateway, the second service gateway can control the node on the functional service chain to forward the message of the target service based on the second network protocol.

S305, the node on the second service gateway control function service chain forwards the message of the target service based on the second network protocol.

The second service gateway determines a transmission path of a message for forwarding the target service on a functional service chain according to the functional service chain configuration information of the network architecture of the target service based on the second network protocol, wherein the transmission path comprises a node for forwarding the message of the target service, and the node comprises at least one first service gateway serving as a forwarding node and a terminal service gateway serving as a terminal node.

For example, the second service gateway may generate a segment routing header (Segment Routing Header, SRH) including a corresponding transmission path according to the functional service chain configuration information, where the SRH includes a series of segment identifiers that specify paths that a message should traverse in the network, so as to accurately control and manage transmission of the message. And adding a second network protocol message header comprising the SRH to the message of the target service so as to control the node on the functional service chain to forward the message of the target service based on the second network protocol.

According to the method provided by the embodiment of the application, the service orchestrator determines the target application server corresponding to the target service according to the type of the service request and the mapping relation between the service type and the application server, and generates the configuration information of the functional service chain of the target service based on the second network protocol according to the first service gateway corresponding to the target application server and the second service gateway, so that the second service gateway can control the node on the functional service chain to forward the message of the target service based on the second network protocol according to the configuration information, and the problem of limited service data transmission is avoided.

Next, how the second service gateway controls the node on the functional service chain to forward the message of the target service based on the second network protocol in the foregoing step S305 will be described in detail.

Fig. 4 is a flow chart of another communication method according to an embodiment of the present application. As shown in fig. 4, the foregoing step S305 may include:

s401, the second service gateway receives an initial message of the target service based on the first network protocol.

The target service is sent to the second service gateway for the service initiator user network node based on an initial message of the first network protocol. The initial message includes service data to be processed by a target application server of the target service. The second service gateway receives an initial message of the target service through a network connection based on a first network protocol with a service initiator user network node.

And S402, the second service gateway is a second network protocol message header of the initial message Wen Tianjia according to the functional service chain configuration information.

The second network protocol message header is used for indicating a first service gateway node on a transmission path of the message of the target service. The second service gateway determines a first service gateway node included in the transmission path according to the transmission path of the message of the target service included in the functional service chain configuration information. For example, the identifier of the first service gateway node may be extracted, for example, the identifier of the name, the serial number, etc. of the first service gateway node, or the network address of the first service gateway node may be extracted, the identifier of the first service gateway node and/or the network address of the first service gateway node is added to a blank second network protocol message header, so as to generate the second network protocol message header corresponding to the functional service chain configuration information.

One possible implementation manner, the second network protocol header includes only the first service gateway node on the transmission path of the message of the target service.

One possible implementation manner includes a first service gateway node on a transmission path of the message of the target service in the second network protocol message header, and a transmission sequence of the first service gateway node. The implementation mode can be realized by the following steps:

s4021, the second service gateway obtains a first service gateway list of a target application server corresponding to the target service and a transmission path of the target service according to the function service chain configuration information.

In one possible implementation manner, the function service chain configuration information may include a first service gateway list of a target application server corresponding to a target service, and a transmission path of the target service, and the second service gateway directly extracts the first service gateway list of the target application server corresponding to the target service, and the transmission path of the target service.

In another possible implementation manner, the functional service chain configuration information includes a target application server and a destination service gateway corresponding to the target service, determines a first service gateway node corresponding to each target application server according to the second service gateway and the target application server, and determines a transmission path of the target service on the first service gateway node as a transmission path of the target service according to an order in which the target application servers process the target service.

S4022, the second service gateway generates a second network protocol message header according to the identification of the first service gateway included in the first service gateway list and the transmission path of the target service.

The identification of the first service gateway may be the SID of each first service gateway, or may be the name of each first service gateway, and the SID of each first service gateway is ordered according to the transmission sequence of the first service gateway in the transmission path according to the transmission path of the target service, so as to generate a second network protocol header including the SID of the first service gateway and the SRH of the transmission sequence of the first service gateway.

For example, assuming that the SID of the first service gateway on the transmission path of the target service is SID-a and SID-B in sequence, the Segment List of the generated SRH (Segments left=2) may be: < Segment List [0] =sid-B, segment List [1] =sid-a >.

S403, the second service gateway generates a message of the target service for the initial message Wen Tianjia added with the second network protocol message header.

The first network protocol header is used for packaging the initial message added with the second network protocol header into a message based on a first network protocol, so that the message of the target service can be transmitted to the first service gateway through a tunnel between the second service gateway and the first service gateway on the transmission path, wherein the tunnel converts the second network protocol into the first network protocol, namely, the initial message added with the second network protocol header can be transmitted to the first service gateway.

S404, the second service gateway sends the message of the target service to the first service gateway on the transmission path.

The second service gateway transmits the message of the target service to the first service gateway through a tunnel between the second service gateway and the first service gateway on the transmission path, wherein the tunnel converts the second network protocol into the first network protocol, so that the first service gateway can forward the initial message to the corresponding target application server for service processing.

And in the transmission process of the message, the first network protocol address of the second service gateway is taken as a source address, the first network protocol address of the first service gateway is taken as a destination address, and the message is sent from the second service gateway to the first service gateway.

According to the method provided by the embodiment of the invention, the second service gateway receives the initial message of the target service based on the first network protocol, the initial message is the second network protocol message header of the initial message Wen Tianjia according to the configuration information of the functional service chain, and the initial message added with the second network protocol message header is transmitted to the first service gateway in the functional service chain by converting the second network protocol into the tunnel of the first network protocol, so that the initial message based on the first network protocol can be transmitted between the second service gateway and the first service gateway, and the problem of limited service data transmission is avoided.

The following details of how the first service gateway forwards the message of the target service.

Fig. 5 is a flow chart of another communication method according to an embodiment of the present application. As shown in fig. 5, the method may include:

s501, a first service gateway receives a message based on a first network protocol of a target service sent by a last gateway on a functional service chain.

The last gateway is a second service gateway on the functional service chain, or other first service gateways, and the message of the target service is encapsulated with an initial message and a second network protocol message header.

If the functional service chain includes a plurality of first service gateways and the current first service gateway is not the first service gateway on the transmission path of the message of the target service, the last gateway is the previous first service gateway of the current first service gateway in the transmission path. If the current first service gateway is the first service gateway on the transmission path of the message of the target service, the last gateway is the second service gateway on the functional service chain. If the functional service chain only includes one first service gateway, the last gateway is a second service gateway on the functional service chain.

S502, the first service gateway acquires an initial message and a second network protocol message header from the message.

In one possible implementation, since the packet of the target service encapsulates an initial packet and a second network protocol packet header, the first service gateway may directly extract the initial packet and the second network protocol packet header from the packet.

In another possible implementation manner, the first service gateway may strip the header included on the initial packet layer by layer to obtain the initial packet, and the second network protocol header. And stripping the first network protocol header of the outer layer in the message to obtain an initial message with the second network protocol header, wherein the first network protocol header of the outer layer is added for passing through a tunnel based on a network protocol conversion protocol. And stripping the second network protocol message header to obtain an initial message, and the second network protocol message header.

S503, the first service gateway sends the initial message to the target application server according to the second network protocol message header.

The second network protocol message header includes a first network protocol address of the first service gateway and a first network protocol address of the target application server, where the two addresses may be stored in address storage locations corresponding to the identifier of the first service gateway, and according to the two addresses, the initial message may be packaged into a first network protocol message transmitted based on the two addresses, and the initial message is sent to the target application server through a tunnel between the first service gateway and the target application server based on the first network protocol.

After receiving the initial message, the target application server processes the service data in the initial message according to the service requirement and generates a response message based on the initial message according to the processed service data. The service processing process can be determined according to actual requirements, and the processing mode can be any existing service processing mode, which is not limited in the application.

S504, the first service gateway receives a response message of the target application server based on the initial message.

After generating a response message based on the initial message, the target application server sends the response message to the first service gateway based on a first network protocol message header comprising a first network protocol address of the first service gateway and the first network protocol message header of the first network protocol address of the target application server, so that the first service gateway can receive the processed service data, and subsequent forwarding operation is executed.

S505, the first service gateway generates a message added with a second network protocol message header according to the response message.

One possible implementation manner may be to re-add the second network protocol header stripped from the initial packet to the reply packet according to the reply packet, so that the first service gateway may determine, according to a first service gateway list included in the second network protocol header, a service gateway to which the reply packet needs to be forwarded subsequently. For example, the identifier of the first service gateway may be obtained, and the service gateway corresponding to the identifier after the identifier is used as the service gateway to which the response message needs to be forwarded subsequently.

In another possible implementation manner, the identifier of the first service gateway in the first service gateway list included in the second network protocol header stripped from the initial packet is deleted, so as to indicate that forwarding of the first service gateway is completed, thereby generating a new second network protocol packet header, adding the new second network protocol packet header to the response packet, and generating a packet added with the second network protocol packet header.

S506, the first service gateway generates the message of the target service for the initial message Wen Tianjia added with the second network protocol message header.

The function of the first service gateway for the initial message Wen Tianjia added with the second network protocol header is the same as that in the step S403, and will not be described herein.

S507, the first service gateway sends the message of the target service to the next gateway on the functional service chain.

The next gateway is other first service gateways or destination service gateways, and the destination service gateways support the first network protocol and the second network protocol. If the first service gateway needs other first service gateways to forward the message to other application servers for processing after the first service gateway is in the transmission path of the target service, the next gateway is the other first service gateway; if the target service is processed by all application servers, the message of the target service needs to be distributed to the user network node of the service receiver through the terminal service gateway, so that the next gateway is the terminal service gateway.

The first service gateway sends the message of the target service to the next gateway on the functional service chain through the tunnel converting the second network protocol into the first network protocol.

S508, the terminal service gateway receives the message of the target business based on the first network protocol sent by the last gateway on the functional service chain.

The last gateway is a first service gateway on a functional service chain, the end service gateway is a forwarding service gateway corresponding to a service receiver user network node of the target service, and is used for distributing a message of the target service to the service receiver user network node corresponding to the target service, and the last gateway is the last first service gateway on a message transmission path in the functional service chain.

S509, the terminal service gateway acquires a response message from the message of the target service.

The terminal service gateway obtains a second network message header of the response message and the response message by stripping the message header of the message of the target service.

Optionally, the second network message header of the response message further includes an operation instruction configured for an identifier of the service gateway, for the first service gateway, the operation instruction corresponding to the identifier of each first service gateway is a forwarding message to the target application server, and for the destination service gateway, the operation instruction corresponding to the identifier of the destination service gateway is a response message extracted from the message of the target service. And the terminal service gateway acquires the response message from the message of the target service according to the operation instruction configured for the identifier in the second network message header of the response message.

And S510, the terminal service gateway transmits the response message to a receiver of the target service through the communication connection based on the first network protocol.

After stripping the second network message header of the response message, the terminal service gateway determines the network address based on the first network protocol of the service receiver user network node of the target service according to the receiver address included in the first network message header at the inner side of the response message, so as to send the response message to the corresponding service receiver user network node according to the network address based on the first network protocol.

According to the method provided by the embodiment of the invention, the first service gateway sends the message to the target application server for processing through the first network protocol by stripping the second network protocol message header of the message of the target service, receives the processed response message, and after the processing is completed, the first service gateway transmits the response message to the next designated gateway through the second network protocol message header which is the response message Wen Tianjia again until the terminal service gateway receives the response message processed at least once, and distributes the response message to the service receiver of the target service, so that the problem of service data transmission limitation is avoided through the function of processing the service based on the functional service chain of the second network protocol under the architecture of the first network protocol.

In the following, a detailed description is given of how to send the initial message to the target application server according to the second network protocol header. The aforementioned step S503 may include:

s5031, the first service gateway obtains the network address of the target application server based on the first network protocol from the second network protocol message header.

The network address of the target application server based on the first network protocol may be stored in the second network protocol packet header, for example, the network address of the target application server corresponding to the first service gateway based on the first network protocol may be configured for the SID of each first service gateway in advance.

The first service gateway can obtain the network address of the target application server based on the first network protocol from the second network protocol message header according to the identifier of the first service gateway, for example, obtain the network address of the target application server corresponding to the first service gateway configured by the SID of the first service gateway based on the first network protocol.

Or, the first service gateway stores the addresses of all application servers connected with the first service gateway in advance, and extracts the network address of the target application server based on the first network protocol from the addresses of all application servers connected with the first service gateway according to the target application server indicated in the second network protocol message header.

S5032, the first service gateway changes the first network protocol message header of the inner layer of the initial message into the first network protocol message header of the target, and generates a message to be processed.

The first network protocol message header of the inner layer of the initial message is a message header of the initial message, the input interface of the target first network protocol message header is a network address of the first service gateway based on the first network protocol, and the output interface of the target first network protocol message header is a network address of the first application server based on the first network protocol.

The first service gateway can send the message to be processed to the target application server through the target first network protocol message header.

S5033, the first service gateway sends the message to be processed to the target application server.

The first service gateway sends the message to be processed to the target application server so that the target application server can process the service data included in the message to be processed, and returns the processed message to the first service gateway according to the input interface of the target first network protocol message header so that the first service gateway can continuously forward the processed message to the next gateway.

In the above implementation manner, the step S505 may include:

s5051, replacing the first network protocol message header of the response message with the first network protocol message header of the inner layer.

The first network protocol message header of the response message is a target first network protocol message header, and the first network protocol message header of the target first network protocol message header is replaced by an inner layer first network protocol message header of the initial message, so that the format of the response message is the same as that of the initial message, and the subsequent continuous transmission of the initial message is facilitated.

S5052, adding a second network protocol message header comprising the residual transmission path for the response message added with the inner layer first network protocol message header according to the residual transmission path of the target service.

The remaining transmission paths are transmission paths of the message of the target service, including transmission paths of all nodes after the first service gateway node, and may be stored in the second network protocol header in a similar manner to the transmission paths of the target service.

And adding the second network protocol message header storing the rest transmission paths to the response message to instruct the first service gateway and how the next gateway forwards the response message.
