Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to an SRv6 path quality measurement method and apparatus, an electronic device, and a storage medium.
Background
SR (Segment Routing) is a protocol designed based on the concept of source Routing to forward packets over a network. The SR divides the network path into segments and assigns segment identifications to the segments and network element nodes. By arranging the segment identifiers in order, a forwarding path can be obtained.
The SR includes two technical schemes, namely SR-MPLS based on MPLS (Multi-Protocol Label Switching) forwarding plane and SRv6(Segment Routing IPv6 based on IPv6 forwarding plane) based on IPv6 forwarding plane: in SR-MPLS, Segment is MPLS label, the entrance node presses multiple labels at one time to form Segment List, and each hop forwards by adopting label searching and label popping actions; in SRv6, Segment is an IPv6 address, and a path is an IPv6 address stack encapsulated in an SRH (Segment Routing Header), and forwarding of each hop is implemented by using a standard forwarding action of pure IPv6, so as to achieve simple processing of normalizing a forwarding plane. Compared with SR-MPLS, SRv6 has better scalability and flexibility, and is now an industry-recognized next-generation Network platform, which is an important basis for SDN (Software Defined Network).
In order to respond to network quality changes in a timely manner and to make network quality of service visible, operators need to measure and monitor network quality of service and provide data that can account for network quality of service, which is no exception to SDN networks using SRv 6. But none of the existing technical means truly reflects the quality of the path.

Detailed Description
The technical solution in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Before describing the SRv6 path quality measurement method provided by the embodiment of the present application, it is necessary to briefly describe the existing SRv6 forwarding process:
IPv6 is an abbreviation for "Internet Protocol Version 6" (Internet Protocol Version 6) in english, and is a next-generation IP Protocol designed by the Internet Engineering Task Force (IETF) to replace IPv 4.
SRv6 is a network forwarding technology, namely the combination of IPv6 and Segment Routing technology, SR is Segment Routing (Segment Routing) technology, v6 is original IPv6, IP forwarding and tunnel forwarding are unified, and the method has the flexibility and strong programmability of IPv 6.
Referring to fig. 1, fig. 1 is a schematic diagram of an IPv6 message structure in an SRv6 forwarding manner in the prior art. As shown in fig. 1, SRv6 inserts a Segment routing extension header SRH into the IPv6 message, where the SRH includes an IPv6 address stack representing path information, i.e., a Segment List (Segment List), and the hop-by-hop forwarding from the ingress node to the egress node is completed by the operation of continuously updating the destination address and offset address stack by the intermediate node. After inserting SRH, the IPv6 message consists of IPv6 standard header, SRH and load.
Referring to fig. 2, fig. 2 is a flowchart illustrating a step of determining a destination address based on a segment list in an SRv6 forwarding manner in the prior art. The entrance node inserts an SRH containing corresponding Segment List information into the IPv6 message according to the SRv6Segment List used by the service message, replaces the destination address with Segment List [ n ], and then checks the IPv6 routing table according to the new destination address for forwarding. Wherein n in Segment List [ n ] is a positive integer and represents the nth Segment ID. Where SL represents the value of x in Segment List [ x ], where x is any positive integer.
After each subsequent node device receives the IPv6 message, if the destination address is not the Segment identifier of the device, routing and forwarding are performed according to the route, if the destination address is the Segment identifier of the device, the field value of the remaining Segment (Segment Left) in the SRH needs to be reduced by 1, and according to the fact that the value of the Segment Left field is not 0, the address of the next hop is determined from the Segment List, the destination address of the IPv6 header is replaced by the address of the corresponding next hop in the Segment List, and after the replacement is completed, the IPv6 routing table is searched according to the new destination address for forwarding. The flow processing is continued until the field value of Segment Left in the received SRH is 0, and the message is forwarded to the exit node after completing the forwarding processing.
The applicant has found that none of the prior art measures can measure the quality of the SRv6 path well, for example:
(1) NQA (Network Quality Analysis): and constructing messages according to the types of the statistical examples to perform network performance statistics, and indirectly simulating the packet loss rate of the service messages by counting the packet loss rate of the constructed messages. Therefore, the performance indexes obtained by the NQA statistics have a difference in accuracy, and cannot directly reflect the operation status of the real service of the user in the network, nor can the performance indexes be directly used as a basis for analyzing the network performance.
(2) IP-FPM (P Flow Performance Monitor, IP Flow Performance Monitor): the method is a measuring mode for directly measuring the service message on the basis of end-to-end so as to obtain the performance indexes of the IP network, such as real packet loss rate, time delay and the like. But in its implementation principle, two reserved bits in the IPv4 header are used as the lost packet dye bit and the time-delayed dye bit. The scheme is not suitable for IPv6 (no reserved bit is available in the IPv6 header), and the IP-FPM can only measure the end-to-end quality of the service and cannot perform hop-by-hop measurement.
(3) IOAM (In-band Operations, Administration, and Maintenance, In-band operation management and Maintenance): the method is a network flow monitoring technology. By copying the service flow and adding OAM information to the copied flow hop by hop, the sensing and measurement of the flow forwarding path and the forwarding quality can be realized. It needs to duplicate the traffic flow, thus increasing the burden on the network and devices, and also cannot reflect the quality of the service in a complete and true manner.
In order to solve the problem that the path quality cannot be truly reflected SRv6 in the prior art, the embodiment of the present application provides a SRv6 path quality measurement method, which is applied to an ingress node. Referring to fig. 3, fig. 3 is a schematic flow chart of an SRv6 path quality measurement method applied to an ingress node according to an embodiment of the present application, where the specific steps of the SRv6 path quality measurement method may be as follows:
step S12: and inserting a segment routing extension header into the IPv6 message, wherein the segment routing extension header comprises a segment residual field value and a segment list corresponding to the IPv6 message.
Still as shown in fig. 2, the ingress node inserts an SRH containing the Segment residual field value and corresponding Segment List information in the IPv6 message according to the SRv6Segment List used by the service message.
The segment remaining field values may be used to determine the corresponding segment identities of the ingress node and the next hop node in the segment list.
Step S14: and modifying the destination address of the IPv6 message based on the segment remaining field value and the segment list.
Specifically, taking the Segment identifier corresponding to the next hop of the current entry node as Segment List [ n ], the destination address of the IPv6 message is modified into the Segment List [ n ] corresponding to the entry node.
Step S16: and replacing the segment identifier of the next hop node corresponding to the inlet node in the segment routing extension head with measurement data for measuring the path quality corresponding to the inlet node and the next hop node to obtain a first message.
Optionally, the present embodiment replaces 16 bytes of Segment List [ n ] in SRH with measurement data for representing path quality, but the present embodiment does not limit the specific format and usage of the measurement data.
Step S18: and forwarding the first message based on the destination address.
And then, according to the step S14, the IPv6 routing table is searched for replacing the obtained new destination address so as to forward the first message.
In the above steps, the ingress node inserts a segment routing extension header into the IPv6 message, and after determining a segment identifier corresponding to a next-hop node of the current node and a segment list in the segment routing extension header, replaces the segment identifier corresponding to the next-hop node with measurement data for measuring the path quality corresponding to the current node and the next-hop node, so that the SRv6 path quality can be reflected according to the measurement data of each node, and meanwhile, the quality of the SRv6 path can be measured hop by hop based on the measurement data of each node.
After the ingress node sends the first packet, it may be that the intermediate node or the egress node receives the first packet, so that the next node performs different processing on the first packet according to the intermediate node or the egress node, which is the first packet, after receiving the first packet.
Referring to fig. 4, fig. 4 is a schematic flow chart of an SRv6 path quality measurement method applied to an intermediate node or an egress node according to an embodiment of the present application, where the specific steps of the SRv6 path quality measurement method may be as follows:
step S21: receiving a first message sent by an entrance node.
Step S22: and when the destination address of the first message is the segment identifier of the node and the remaining field value of the segment is not 0, determining that the node is an intermediate node.
When the node is determined to be an intermediate node, before sending the received message, the field value of the field of Segment Left (Segment Left) needs to be subtracted by 1.
It should be understood that, since Segment and Segment Identifier (SID) in Segment List of SRH are commonly mixed, Segment List [ n ], Segment List [ n-1], etc. in Segment List of SRH are each referred to as Segment Identifier in the present embodiment, and each node of ingress node, intermediate node, etc. is also referred to as Segment Identifier for SRv6 being IPv6 address.
Step S23: and modifying the destination address of the first message into the segment identifier of the next hop node corresponding to the node in the segment routing extension head of the first message so as to obtain a second message.
And determining a Segment identifier corresponding to a next hop node in a Segment routing extension header of the first message from the Segment List according to the Segment Left field value, taking the Segment identifier as a next hop destination address, and replacing the IPv6 head destination address with the corresponding next hop destination address in the Segment List.
Step S24: and replacing the segment identifier of the next hop node corresponding to the node in the segment list of the segment routing extension head of the second message with measurement data for measuring the path quality corresponding to the node and the next hop node to obtain a third message.
After the replacement of the destination address is completed, the Segment identifier of the next hop node of the current node, which corresponds to 16 bytes in the current Segment List, is replaced by measurement data for representing the path quality between the current node and the next hop node according to the path quality information between the current node and the next hop node.
Step S25: and forwarding the third message based on the destination address of the third message.
And searching an IPv6 routing table according to the new IPv6 destination address to forward the third message.
Step S26: and when the destination address of the first message is the segment identifier of the node and the residual field value of the segment is 0, determining the node as an exit node.
And continuing the forwarding processing of the intermediate device until the Segment Left field value in the SRH of the received message is 0 and the destination address is the Segment identifier of the node, and finishing the forwarding processing of the message to reach the final destination node, namely the exit node.
In order to determine the path quality more accurately and directly, the egress node or the intermediate node may calculate the complete hop-by-hop quality measurement data of the path corresponding to the SRv6Segment List based on the measurement data, and the intermediate node of any one path may also calculate the hop-by-hop quality measurement data to the node.
Optionally, the egress node may calculate, based on the measurement data and data such as the packet receiving time of the node receiving the first packet, the node delay, the link delay, the delay jitter, the hop-by-hop packet loss rate, and the like on the path corresponding to the SRv6segment list of the first packet.
In order to make the SRv6 path quality measurement method provided by the embodiment of the present application easier to understand, the present embodiment explains it by the following example:
three SRv 6-supporting devices R1, R2 and R3 are arranged in the network, SIDs of the devices are 1::1, 2::1 and 3::1 respectively, and forwarding information learning and high-precision clock synchronization are completed. Referring to fig. 5, fig. 5 is a schematic structural diagram of a node path according to an embodiment of the present disclosure, including an ingress node R1, an intermediate node R2, and an egress node R3.
The ingress node R1 inserts an SRH containing corresponding Segment List information into the IPv6 message according to the SRv6Segment List used by the service message: segment Left is 1, Segment List [0] is 3::1, Segment List [1] is 2::1, the destination address is replaced by Segment List [1], namely 2::1, then Segment List [1] in the SRH is replaced by measurement data for representing the path quality between the node and the next hop node, and finally the message is forwarded to R2 by looking up an IPv6 routing table according to the new destination address 2:: 1.
The scheme of the present invention is not limited to the specific format and usage of the measurement data stored in the SRH, and for convenience of description, the format of an embodiment of the measurement data is shown in fig. 6 and includes a received packet timestamp, a sent packet timestamp, and a sent sequence number. The unit of receiving the message timestamp is nanosecond, and the unit of sending the message timestamp is nanosecond.
For the measurement data stored in R1, the received packet timestamp is the time when the packet is received by R1, the sent packet timestamp is the time when the packet is sent by R1, and the sent packet sequence number is the message sending sequence number of R1. Based on the timestamp stored in R1 for sending the message, R2 can calculate the link delay between R1 and R2 according to the time for receiving the message, and calculate the delay jitter between R1 and R2 according to the link delay. R2 may calculate packet loss rates of R1 to R2 based on the transmission sequence number; since the packet loss rate is calculated independently hop by hop, the packet loss rate calculated by the node may also be filled in the segment identifier corresponding to the next-hop node of R2 in the SRH as the measurement data.
After receiving the message, the intermediate node R2 judges that the destination address 2::1 is the SID of the device, the field value of Segment Left in the SRH needs to be reduced by 1, the next hop node address is determined to be Segment List [0] according to the Segment Left field value being 0, namely 3::1, the destination address of the IPv6 head is replaced by 3::1, then the current Segment List [0] is replaced by measurement data used for representing the path quality between the node and the next hop node, and finally the IPv6 routing table is checked according to the new destination address 3::1 to forward the message to the R3.
For the measurement data stored in R2, the timestamp of receiving a packet filled in the Segment List [0] is the time when the packet is received by R2, the timestamp of sending a packet is the time when the packet is sent by R2, the sending sequence number is the sending sequence number of the packet with R2, and the packet loss rate is a value calculated based on the sending sequence number in the measurement data of R1 in the packet and the packet reception statistics of R2 in a certain time period. R2 can also calculate the node delay, link delay and delay jitter of R1- > R2 based on the received message timestamp, the sent message timestamp and the message receiving time of the node in the measurement data field of R1 in the message.
After the R3 receives the message, it is determined that the destination address 3: 1 is the SID of the device and the Segment Left field value in SRH is 0, and the message is forwarded to the exit node. Based on the measurement data of R1 and/or R2 in the message and the statistical data such as the message receiving time of the local device, R3 can calculate at least one network path quality measurement data of the time delay of each node of the path R1- > R2- > R3 corresponding to the SRv6Segment List, the link time delay between two nodes, the time delay jitter of two nodes, and the hop-by-hop packet loss rate.
In order to better match the SRv6 path quality measurement method applied to the ingress node provided in this embodiment, the present embodiment further provides a SRv6 path quality measurement apparatus 30 applied to the ingress node.
