Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present invention, numerous technical details have been set forth in order to provide a better understanding of the present invention. However, the claimed invention may be practiced without these specific details and with various changes and modifications based on the following embodiments. The following divisions of the embodiments are for convenience of description, and should not be construed as limiting the specific embodiments of the present invention, and the embodiments may be mutually combined and referred to without contradiction.
One embodiment of the present invention relates to an IOAM processing method, and a specific flow is shown in fig. 1.
In this embodiment, key information of a target traffic flow for which in-band operation maintenance management IOAM is required is maintained, where the key information includes: dyeing marks, time stamp enabling marks, hop-by-hop detection marks and dyeing periods; the key information is carried in a service flow label inserted in the target service flow by the head node; the hop-by-hop detection mark is used for indicating whether the node other than the head node needs to perform performance statistics of the target service flow or not; and under the condition that the performance statistics of the target service flow are required to be carried out, carrying out the performance statistics of the target service flow according to the dyeing mark, the time stamp enabling mark and the dyeing period.
Compared with out-of-band detection technologies, such as OAM technology based on protocol ITU-T Y.1731 and bidirectional active measurement protocol (TWAMP) detection technology, the IOAM technology has the important advantages of simple configuration, fast sensing, accurate network performance fault positioning and the like, the forwarding path is consistent with the real service path, and the end-to-end and hop-by-hop performance detection can be performed on the service flow without additionally inserting detection OAM messages into the service flow.
The traditional IOAM technology can bring better operation and maintenance service in the aspects of packet loss rate, time delay measurement and the like, but a network controller is required to configure nodes in a service flow transmission path respectively, and the problems of long configuration interaction path, slow flow path and information change perception, large occupied device bandwidth, large performance pressure of the network controller and the like exist when thousands of service flows pass through the same node in the face of a high-flow scene.
The following details of implementation of the IOAM processing method in this embodiment are described specifically, which are only for convenience in understanding the implementation details of the present embodiment, and are not necessary to implement the present embodiment. The specific flow is shown in fig. 1, and may include the following steps:
Specifically, the head node inserts a service flow label in a target service flow needing to be subjected to IOAM, wherein the service flow label carries key information of the target service flow. These key information include: dye marks, timestamp enable marks, hop-by-hop detection marks, and dye cycles. The hop-by-hop detection mark is used for indicating whether the node other than the head node needs to perform performance statistics of the target traffic flow. If the hop-by-hop detection mark indicates that the nodes in the path all need to perform performance statistics of the target service flow, the hop-by-hop performance detection is performed on the target service flow, and if only the head node and the tail node in the transmission path perform performance statistics of the target service flow, the end-to-end performance detection is performed on the target service flow. A schematic structure of a traffic flow label inserted by the head node in the target traffic flow may be shown in fig. 2.
The bootstrap tag in the traffic flow tag as shown in fig. 2 is used for the node in the transmission path to identify the IOAM traffic flow; l bits in the service flow label are dyeing marks; l bits in the service flow label are time stamp enabling marks; the H bit in the service flow label is a hop-by-hop detection mark; the T bits in the traffic label are the dyeing period.
The meaning of the other fields in the traffic flow label is as follows: TC: traffic Control, traffic management; s: stack, stack bottom mark; TTL: time To Live, time To Live; user Payload: a user payload; flow ID: and (5) identifying the service flow.
In the example that one node is the head node in the communication path, before maintaining the key information of the target service flow for the target service flow to be subjected to in-band operation maintenance management (IOAM), the target service flow to be subjected to IOAM can be determined according to the IOAM configuration information issued by the controller, and a service flow label inserted into the target service flow is generated according to the IOAM configuration information; maintaining key information of the target traffic flow for the target traffic flow requiring in-band operation maintenance management (IOAM) may include: and maintaining key information of the target service flow according to the IOAM configuration information. In this example, the node is a head node in the transmission path, and the head node can generate a service flow label inserted into the target service flow, so that a subsequent node in the transmission path can count the performance of the target service flow according to key information in the service flow label, and the configuration of a controller to a node other than the head node is avoided.
In actual implementation, the structure of the head node involved in this example may be as shown in fig. 3. The OAM module of the head node may receive the IOAM configuration information issued by the controller and configure an access control list (Access Control Lists, abbreviated as "ACL") module. Further, ACL modules configure device hardware such as a network processor (Network Processor, abbreviated as "NP"). The head node may contain an OAM module and an NP module. The OAM module may include an IOAM configuration module and an upload processing module. The NP module can comprise a flow matching module, a flow dyeing module, a service flow label packaging module and a performance statistics module. The OAM module may issue a field programmable gate array (Field Programmable Gate Array, simply "FPGA") staining signal to the NP module.
In the example where a node is a non-head node in the communication path, before maintaining key information of a target service flow for the target service flow to be subjected to in-band operation maintenance management IOAM, the target service flow to be subjected to IOAM may be determined according to a service flow identifier of the service flow; generating IOAM configuration information according to the service flow label under the condition that the hop-by-hop detection mark indicates that performance statistics of the target service flow is needed and the target service flow belongs to the unsubscribed service flow; maintaining key information of the target traffic flow for the target traffic flow requiring in-band operation maintenance management (IOAM) may include: and maintaining key information of the target service flow according to the generated IOAM configuration information. In this example, the node is a node other than the head node in the transmission path, so that IOAM configuration information can be generated for the target service flow to be subjected to IOAM, and the configuration pressure of the controller can be effectively reduced without configuring the IOAM configuration information by the controller. The structure of the nodes other than the head node involved in this example may be as shown in fig. 4. In actual implementation, the nodes other than the head node may include an OAM module and an NP module. The OAM module may include an IOAM configuration module, a flow analysis module and an upload processing module. The NP module may include a stream matching module and a performance statistics module.
In the case that the node other than the head node is the tail node in the communication path, after maintaining the key information of the target traffic flow for the target traffic flow to be subjected to in-band operation maintenance management IOAM, the traffic flow label in the target traffic flow can be removed. After the traffic flows through the tail node, the IOAM traffic is terminated, and in this example, the tail node can reject the traffic labels in the traffic.
The tail node is a special node in the transmission path, and in actual implementation, the node can be issued by the controller to be configured to be the tail node of a certain service flow or generated by self-subscription at the last hop of the service flow label.
In the case where performance statistics of the target traffic flow is required in this step, that is, the node executing the IOAM processing method in this embodiment is a head node, or the node is a node other than the head node and the hop-by-hop detection flag indicates that performance statistics of the target traffic flow is required.
In one example, a node includes a first statistical module and a second statistical module that are independent of each other, a first register corresponding to the first statistical module, and a second register corresponding to the second statistical module; according to the dyeing mark, the time stamp enabling mark and the dyeing period, the performance statistics of the target service flow can be carried out, and the method can comprise the following steps: the first statistics module and the second statistics module are alternately used for counting the performance of the target service flow according to the dyeing marks; the first statistics module and the second statistics module are used for counting the performance of the target service flow according to the dyeing mark, the time stamp enabling mark and the dyeing period, the first statistics module obtains a statistics result and stores the statistics result into a first register, and the second statistics module obtains a statistics result and stores the statistics result into a second register.
And for the service flows with the same dyeing marks, carrying out performance statistics by using the same statistics module. The L bit and OAM module synchronize FPGA dyeing signals issued by NP, and D bit is set when L bit is turned over and is used for counting time stamps when L bit changes. In actual implementation, the performance statistics may include traffic information statistics and time stamp information statistics. The traffic information takes the incoming statistics of the traffic stream, and if the D bit is set, the time stamp information is recorded. The flow and time stamp information can be directly put into a special register divided according to the service flow identification, and is not circulated in the NP along with the message.
After performance statistics of the target traffic flow are performed, the method may further include: reading a statistical result from the first register or the second register according to the dyeing period and the current dyeing mark; and reporting the read statistical result to an acquisition server through a remote sensing survey test channel.
In practical implementation, the OAM module may periodically read the performance statistics according to the dyeing period of the service flow, and select the register where the read statistics is located according to the state of the L bits in the key information of the service flow. And if the L bit is set, setting the first statistics module to perform performance statistics on the target service flow, and if the L bit is set, reading the performance statistics result of the second register by the OAM module. The OAM module can package the performance statistics result of the service flow and the input interface information of the service flow, such as an interface, a single board, a device number and the like, and the integrated compressed data is sent to the controller through a test channel.
Reporting the read statistical result to an acquisition server through a telemetry channel, which can comprise: grouping the statistical results according to the reported acquisition servers, wherein the reported objects are the statistical results of the same acquisition server and are divided into the same group; compressing and packaging the statistical results of the same group and reporting the statistical results; and under the condition that the data volume after compression and packaging is larger than the transmission performance of the telemet channel, the data after compression and packaging is subjected to fragment reporting.
In this embodiment, the NP and the OAM module are required to jointly maintain information of a local service flow, and in practical application, a node may aggregate a large amount of service flows, the frequency of traffic triggering NP to subscribe the service flows is far higher than that of the service flow information operation of the OAM module, at this time, the module time generates competition, a large amount of burst flows affect the addition and deletion of the existing service flows, and the service flow statistics result, the service flow configuration and the control information are put together, which also may cause the OAM module to fail to read due to the concurrency problem. Considering the hardware isomerism of NP and OAM modules, the general software lock is difficult to meet the performance requirement, so that the information of the service flow can be split and stored in a service flow identification table, a service flow control table and a service flow statistical result table in actual implementation. A schematic diagram of the interaction of NP and OAM modules in a node is shown in fig. 5.
For the service flow identification table, the OAM module creates and updates the table, and the NP module only reads the table; for a traffic control table, which contains key information (L, T, H, D) of traffic labels, the NP creates and updates it, and the OAM module only reads the table; for the traffic flow statistics table, in which performance statistics are stored, the NP creates and updates it, and the OAM module only reads the table.
The statistical result of the acquisition server is reported in a test mode, the statistical information reporting structure shown in fig. 6 can be adopted in consideration of the requirement of the distributed acquisition server, and the statistical result can be compressed and packed to follow the protobuf protocol.
In this embodiment, the nodes in the communication path are the target traffic flows for which in-band operation maintenance management IOAM is required, and maintain key information such as a dyeing flag, a time stamp enable flag, a hop-by-hop detection flag, and a dyeing period of the target traffic flows. This critical information is carried in the traffic flow label, which is inserted into the target traffic flow by the head node. The nodes in the communication path can carry out performance statistics of the target service flow according to the dyeing mark, the time stamp enabling mark and the dyeing period in the service flow label, and the nodes of the non-head nodes can determine whether the performance statistics of the target service flow is required according to the hop-by-hop detection mark, so that the network controller is not required to configure all the nodes in the communication path, the performance detection of the service flow can be completed, the IOAM configuration flow can be simplified, and the configuration pressure of the network controller is reduced.
