For a better understanding and implementation, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or modules is not necessarily limited to those steps or modules that are expressly listed or inherent to such process, method, article, or apparatus.
The invention provides a programmable network system based on user requirements, which deploys programmable switch resources according to network requirements selected by users. The period from the requirement selection to the function deployment is short, the reaction is quick, the system automatically checks and processes the dependency relationship of the functions, and related functions are deployed at the same time. Other redundant functions are not additionally deployed outside the functions meeting the user requirements, the switch resources are fully utilized to meet the requirements of more users while the switch processing logic is simplified, and the resource utilization rate and the message processing efficiency are improved. The system can meet the requirements of users, greatly improve the utilization rate of switch resources and can be compatible with expansibility.
In general, a product specification of a switch will specifically give a list of support functions, and a user of the switch needs to look at the list to determine whether the switch meets its own needs. The more functions supported represent the more powerful the switch, but many functions are not needed in practical applications. The user does not need to use a plurality of functions, but needs to pay for the functions, which causes an increase in cost. The switch device manufacturer needs to cover the full enough functions as much as possible to meet the demands of as many clients as possible, resulting in the increase of the manufacturing cost and redundancy of functions of the switch device.
As shown in fig. 1, the present invention provides a schematic structure diagram of a programmable network system based on user requirements, which includes a user network function requirement subsystem, a requirement translation and analysis subsystem, a mirror image, a package file warehouse management subsystem, and a control management plane subsystem. The system can be applied to a switch and other devices with the function of the switch, and the embodiment of the invention is not limited in application of the system.
As shown in fig. 2, the user network function requirement subsystem is configured to receive a network requirement of a user, and the user issues the network requirement by selecting an area. The selection area presents through the selection interface functions that the user can customize, including but not limited to: SRv6, vxlan (Virtual Extensible Local Area Network, virtual extended local area network), MPLS (Multi-Protocol Label Switching, multiprotocol label switching), UPF (User PlaneFunction ), switch, IPv6, EVPN (Ethernet Virtual Private Network, VPN technology for implementing network two-layer interworking), L2VPN, L3VPN.
After receiving the network demands of the users, the user network function demand subsystem sends the interactive key proc files corresponding to the network demands to the demand translation and analysis subsystem in a grpc mode.
As shown in fig. 3, the requirement translating and analyzing subsystem is configured to receive a network requirement sent by the user network function requirement subsystem, and verify and analyze the network requirement to obtain resource requirement information of the network requirement. The demand translation and analysis subsystem is provided with 2 processes, wherein the first process mainly receives network demands and completes function verification and dependency analysis, and the second process is used for receiving feedback signals of users and sending resource deployment signals required by resource demand information according to the feedback signals. The demand translation and analysis subsystem comprises 4 modules, a demand receiving module, a function checking module, a user feedback module and a demand executing module. The user feedback module and the demand execution module belong to a second process.
The demand receiving module is used for receiving keywords of network demands of users, and the function verification module is used for performing function verification and dependency analysis on the keywords to obtain resource demand information of the network demands. The key word is received through the first process, and the key proto file of the used intermediate interaction is consistent with the key proto file of the user network function requirement subsystem.
The function verification module performs function verification on the received keywords, namely, verifies whether the package files corresponding to the keywords exist in the current system, and if the package files corresponding to the keywords exist in the system, the verification is passed. And the dependency analysis refers to analysis of the functional dependency relationship, and the dependency relationship comprises resource dependency and functional dependency. The resource requirement information then includes all the dependencies required by the key. Resource dependencies include base resource dependencies and hardware resource dependencies that are at least needed to run the function. Functional dependencies include, but are not limited to SRv6 dependent ipv6 and the like, MPLS dependent ipv4/v6, igp and the like; EVPN is dependent on ipv4/v6, bgp, igp, etc. The underlying resources include, but are not limited to, routing, IP, etc., while the hardware resources include, but are not limited to, CPU, amount of memory.
The user feedback module is used for sending feedback signals to the user network function requirement sub-module and the requirement execution module after the function verification module completes function verification and dependency analysis. The feedback signals include a deployment signal and a non-execution signal, i.e. "deployment" or "not diagnostic", to inform the user of the current switch deployment. When the feedback signal is a deployment signal, the demand execution module sends a resource deployment signal to inform the dispatching switch of resources and deploy package files with corresponding functions.
As shown in fig. 4, the orchestration/collaboration subsystem is configured to obtain, after receiving the resource deployment signal, a packet file that satisfies the resource requirement information according to the resource requirement information, and deploy the packet file to a switch that satisfies the resource requirement information. The arrangement/collaboration subsystem is realized through 3 processes and comprises a resource management module, a package installation module and a function collaboration module.
The resource management module is used for managing resources of all switches in the system, including but not limited to resources such as CPU, memory, ports and the like. After receiving the resource deployment signal, the resource management module queries the resource information of all the switches to confirm the switch deploying the function. After determining the switch to deploy, a switch deployment signal is issued.
And the packet installation module deploys the packet file meeting the resource requirement information in the switch appointed in the switch deployment signal according to the switch deployment signal. The function coordination module is used for coordinating functions among the plurality of switches, so that the switches of the processing path all have the functions, and message processing is facilitated. By allocating the cooperative paths, the related services are deployed more intelligently and swiftly, and the time cost of development, coordination and configuration is saved.
As shown in fig. 5, the control management plane subsystem is then used for configuration management of switch resources. The control management plane subsystem is realized by 3 processes, and the 3 processes respectively comprise an equipment automatic discovery module, a configuration management module and a resource acquisition module. After the corresponding package file is deployed to the switch by the package installation module, the configuration management module configures a configuration command corresponding to the package file to the switch, so that the function of the switch is normally used.
The resource acquisition module periodically sends a resource report signal to the exchange to acquire the resource information of the equipment, so that the resource management module can conveniently manage the resource for use when the network function requirement subsystem of the user receives the network requirement of the user next time. The resource information comprises, but is not limited to, a memory, a CPU, port resources and deployed functions, and in the invention, a resource report signal is sent every 5 seconds, the resource information is updated in time, and related services are deployed more intelligently and swiftly. And the equipment automatic discovery module automatically acquires the IP of the switch and distributes an IP address for the switch when a new switch exists and joins the system.
Further, as shown in fig. 6, the system further provides a mirror image and package file warehouse management subsystem for managing package files and mirror image files and synchronizing resource requirement information. The subsystem belongs to a prefabricated system and is completed or continuously updated before receiving network requirements. The method is realized by 2 processes and comprises a package storage module and a function synchronization module, wherein the package storage module is used for storing package files and mirror image files and compiling and packaging the package files with the functions. I.e. compiling the package file ready for the function by means of a make sonic/switch. Bin command, placing the package file in a storage directory/user/package. And the function synchronization module sends the function name of the package file prepared by the package storage module to a function verification module of the requirement translation and analysis subsystem so as to synchronize management information of the package file.
Based on the same inventive concept, the invention also provides a programmable network implementation method, which is applied to the programmable network system, and the method comprises the following steps:
the user network function requirement subsystem receives the network requirement of the user;
the requirement translation and analysis subsystem verifies and analyzes the network requirement to obtain resource requirement information of the network requirement;
the arrangement/collaboration subsystem obtains a package file meeting the resource requirement information according to the resource requirement information, and deploys the package file on a switch meeting the resource requirement information so as to deploy the function on the switch;
the control management plane subsystem completes the network configuration of all switches deploying the functions.
The workflow of the present system is described below in connection with the implementation of the SRv function, as shown in fig. 7.
And step 701, responding to the network requirements of the user, and completing verification and analysis of the network requirements through a requirement translation and analysis subsystem.
The user selects SRv function therein through the user network function requirement subsystem, issuing SRv a network requirement. The user network function requirement subsystem sends the keyword 'SRv' to the requirement translation and analysis subsystem in a grpc mode. In the interaction process, the key proto file is defined as follows:
syntax = "proto3";
package srv6_proto;
service RequestCollect {
rpc ReportRequest (Request) returns (Response) {} }
message Response {
string UserRespone = 1;
}
message Request{
string UserRequet = 1；
}
and the requirement translation and analysis subsystem receives the keywords and verifies and analyzes the keywords in the network requirement. Further, the requirement receiving module is configured to receive a keyword of a network requirement, where the related intermediate interaction proto file is consistent with the above. And the function verification module is used for performing function verification and dependency analysis on the keywords to obtain the resource requirement information of the network requirement. The function checking module checks whether a packet file with the function corresponding to Srv6 exists in the current system, namely whether a mirror image and packet file warehouse management subsystem sends a message to the function checking module. And when the packet file with the function corresponding to the keyword exists, checking to pass.
And the function verification module analyzes the dependency relationship of the received keywords to obtain the resource requirement information. The resource requirement information is stored in a file table form as shown in table 1, according to verification detection SRv, the resource dependence comprises 1 CPU and 64M memories, and 2 ports are needed to be used.
TABLE 1
In step S702, the user feedback module sends a feedback signal to the user network function requirement subsystem and the requirement execution module to inform the user of the deployment condition of the network required functions. When the feedback signal is "default," SRv functions are being deployed.
In step S703, the demand execution module sends a resource deployment signal to the resource management module to inform the resource request information. The resource deployment signal can be sent in a tcp mode, and the sending content is as follows: "function: SRv6, dependence: IPv6, CPU:1, memory: 64M, ports: 2).
Step S704, the resource management module receives the resource deployment signal and acquires the resource information of all the switches to confirm the switches deploying the function.
The resource information of the switch is shown in table 2:
TABLE 2
The switch can meet the requirements of SRv functions. To fully utilize the resources, SRv6 functions can be superimposed on the switch 1. The resource management module sends a switch deployment signal, wherein the switch deployment signal is "switch1" + "IPv6" + "Vxlan" + "SRv" and is sent to the packet installation module in the form of tcp.
Step S705, the packet installation module deploys packet files meeting the resource requirement information in the designated switches in the switch deployment signals according to the switch deployment signals; the configuration management module configures SRv6 related configuration commands into the switch that deploys SRv the function package.
The package installation module feeds back switch information switch1 and IPv6"+" Vxlan "+" SRv6 "in switch deployment signals to the mirror image and package file warehouse management subsystem to obtain package files or compile and construct bin packages meeting the functions. Meanwhile, the configuration management module configures a configuration command corresponding to the packet file of SRv to the switch, so that the SRv function of the switch is normally used.
Step S706, the function coordination module coordinates other switches in the path so that the switch meets the forwarding requirement of the specified path. The switch in the SRv path must have an IPv6 function, and the switch at the end node of the path has at least SRv function, and generates an srv6 forwarding path between the head and the tail, so that the message forwarding can be completed. As shown by the switch paths in fig. 1, switches 2, 3, 4, 5 must be IPv6 capable.
Step S707, when step S704 is completed, the configuration management module configures SRv6 related configuration commands to the switch that deploys SRv the function package. And configuring a configuration command corresponding to the packet file of SRv to the switch so that SRv functions of the switch are normally used.
Meanwhile, the resource acquisition module sends a resource report signal to the exchange to acquire the resource information of the equipment, such as the memory, the CPU and the port resource, and reports the resource information to the resource management module for resource management, so as to be used when the network function requirement subsystem of the user receives the network requirement of the user next time.
More, when a new switch joining system exists, the device auto-discovery module controlling the management plane subsystem automatically acquires the IP of the switch and allocates an IP address to the switch: 192.168.1.10/24.
Notably, the image, package file management system belongs to a pre-manufactured system, and is completed or continuously updated before the user selects the function. The package storage module of the first process is responsible for compiling, packaging and storing the functional package of SRv, specifically, the package ready for the function is compiled using a make sonic/switch. The function synchronization module of the second process packages the information of the mobile phone SRv in an update message and synchronously sends the information to the function verification module of the requirement translation and analysis subsystem to synchronize SRv management information of the package file.
