Background

In-band network telemetry is mainly applied to operation and maintenance in a data center network, and a traditional network is based on a passive operation and maintenance mode of CLI and SNMP mechanisms: the monitoring data of the equipment is obtained through a pull mode, and the fault positioning is slow; the acquisition precision is rough, only the acquisition of the minute level can be realized, and the monitored network node data is inaccurate; the lack of a query for device queue status information does not specify fault localization. In-band network telemetry (Inband Network Telemetry) is abbreviated as INT, key information of flow is directly collected by utilizing a switch chip, such as the queue condition of messages, port buffering when the messages are forwarded, and the like, and the collected telemetry messages are sent to an analysis system, so that real-time active network operation and maintenance are realized.

In-band network telemetry has two modes of message output of INT, namely End-to-End, namely telemetry data is added into an original message for transmission, and output is carried out on a last-hop switch. The other is Post-card mode, namely, the original message is not changed, the telemetering data is sent out from each exchanger independently, and although the mode solves the modification of the original message, each hop exchanger outputs the telemetering data, and the reorganization pressure on a back-end analysis system is high.

Fig. 1 is a flowchart of a message transmission method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:

step S102, a preset switch acquires an original message and a first remote measurement message, wherein the original message comprises: the message forwarding method comprises a message header and a message body, wherein the message header is used for indicating a message forwarding path of an original message in an in-band network telemetry domain, the in-band network telemetry domain comprises a plurality of preset switches, and the message header of a first telemetry message is the same as that of the original message;

step S104, inserting in-band network telemetry data of a preset switch into a message body of the first telemetry message to generate a second telemetry message;

step S106, the original message and the second telemetry message are respectively transmitted according to the message header.

In the embodiment of the invention, a preset switch acquires an original message and a first remote measurement message, wherein the original message comprises: the message forwarding method comprises a message header and a message body, wherein the message header is used for indicating a message forwarding path of an original message in an in-band network telemetry domain, the in-band network telemetry domain comprises a plurality of preset switches, and the message header of a first telemetry message is the same as that of the original message; inserting in-band network telemetry data of a preset switch into a message body of the first telemetry message to generate a second telemetry message; respectively transmitting an original message and a second telemetry message according to the message header; the in-band network telemetry data of the original message can be transmitted through the telemetry message without changing the original message, and the original message and the telemetry message have the same message header, so that the telemetry message can be synchronously transmitted according to the message forwarding path of the original message in the in-band network telemetry domain, the in-band network telemetry data of each preset switch are not required to be transmitted respectively, the technical effect of improving the transmission efficiency of the second telemetry message is realized, and the technical problem of low transmission efficiency of the second telemetry message is solved.

In step S102, the in-band network telemetry domain includes a plurality of preset switches, each of which is configured to transmit an original message and a telemetry message, and add in the telemetry message in-band network telemetry data of the preset switch, where the telemetry message may be a first telemetry message or a second telemetry message.

In step S102, the plurality of preset switches in the in-band network telemetry domain may employ a leaf ridge structure.

In the step S102, the original message and the telemetry message both have a message header and a message body, where the message header indicates a transmission path of the message, and the message body carries a payload of the message, and because the original message and the telemetry message have the same message header, the original message and the telemetry message may be transmitted in an in-band network telemetry domain according to the same message forwarding path, where the telemetry message may be a first telemetry message or a second telemetry message.

In the step S102, the in-band network telemetry domain includes an access switch, which is used as an input node of the in-band network telemetry domain and can be connected with a message generating object for generating an original message, and the original message is transmitted into the in-band network telemetry domain.

In step S104, the in-band network telemetry data is INT data.

Optionally, under the condition that the in-band network telemetry domain receives the original message for the first time, the in-band network telemetry domain does not have the telemetry message of the original message yet, and because the access switch is used as an input node of the in-band network telemetry domain, the access switch obtains the original message first, and then the access switch can generate the telemetry message according to the original message.

As an optional embodiment, the obtaining, by the preset switch, the original message and the first telemetry message includes: receiving an original message generated by a message generating object under the condition that a preset switch is an access switch, wherein the access switch is used as an input node of an in-band network telemetry domain; copying the original message to generate an intermediate message; deleting the message body of the intermediate message to generate a first remote measurement message.

According to the embodiment of the invention, after the access switch receives the original message, the original message can be duplicated to generate the intermediate message, then the intermediate message is modified, the message effective load stored in the message body of the intermediate message is deleted, and the first remote measurement message which has the same message head as the original message and has smaller message volume is obtained, so that the first remote measurement message and the original message have the same message synchronization, and the first remote measurement message can be synchronously transmitted according to the message forwarding path of the original message.

As an optional embodiment, the obtaining, by the preset switch, the original message and the first telemetry message includes: and receiving an original message and a first remote measurement message sent by a first switch under the condition that the preset switch is a forwarding switch, wherein the first switch comprises an access switch or other forwarding switches in an in-band network telemetry domain, the access switch is used as an input node of the in-band network telemetry domain, and the forwarding switch is used as a forwarding node of the in-band network telemetry domain.

In the above embodiment of the present invention, in the in-band network telemetry domain, a preset switch other than the access switch receives the original message, and also receives the telemetry message (i.e., the first telemetry message) simultaneously, so that the preset switch only needs to insert its in-band network telemetry data into the message body portion of the first telemetry message.

As an alternative embodiment, inserting in-band network telemetry data of a preset switch in a message body of a first telemetry message, and generating a second telemetry message includes: acquiring in-band network telemetry data of a preset switch; identifying a message body of the first remote measurement message; and inserting in-band network telemetry data into the message body of the first telemetry message to generate a second telemetry message.

In the above embodiment of the present invention, each preset switch for transmitting an original message has corresponding in-band network telemetry data, and in the process of generating a second telemetry message, the in-band network telemetry data of the preset switch may be inserted into a message body portion of a first telemetry message, and arranged behind existing in-band network telemetry data in the message body portion, so that a plurality of in-band network telemetry data may be sequentially inserted into a message body portion of a telemetry message (i.e., the first telemetry message or the second telemetry message).

As an alternative embodiment, acquiring in-band network telemetry data of a preset switch includes: acquiring preconfigured in-band network telemetry data in a cache space of a preset switch; or analyzing the original message acquired by the preset switch to determine in-band network telemetry data.

In the above embodiment of the present invention, in-band network telemetry data of each preset switch may be preconfigured, or may be generated in real time when an original message is received, and according to actual use conditions, in-band network telemetry data may be flexibly acquired in different modes.

As an alternative embodiment, transmitting the original message and the second telemetry message according to the message header includes: under the condition that a preset switch is an access switch or a forwarding switch, a message head is identified, and a message forwarding path is determined, wherein the access switch is used as an input node of an in-band network telemetry domain, and the forwarding switch is used as a forwarding node of the in-band network telemetry domain; and sending the original message and the second telemetry message to a second switch according to the message forwarding path, wherein the second switch comprises a boundary switch or other forwarding switches in an in-band network telemetry domain, and the boundary switch is used as an output node of the in-band network telemetry domain.

In the above embodiment of the present invention, when the preset switch is an access switch or a forwarding switch, the original message and the telemetry message (such as the second message) need to be transmitted in the in-band network telemetry domain, and further, by analyzing the message headers of the original message and the telemetry message (such as the second message), the message forwarding paths of the original message and the telemetry message can be determined.

As an alternative embodiment, transmitting the original message and the second telemetry message according to the message header includes: under the condition that a preset switch is a boundary switch, identifying a message processing object of which the message head is determined to receive an original message, wherein the boundary switch is used as an output node of an in-band network telemetry domain; and sending the original message to a message processing object, and sending the second remote measurement message to a back-end analysis object.

In the above embodiment of the present invention, since the boundary switch is used as the output node of the in-band network telemetry domain, in the case that the preset switch is the boundary switch, it indicates that the original message and the telemetry message (such as the second message) need to be output from the in-band network telemetry domain, and since the message bodies of the original message and the telemetry message (such as the second message) are different, the original message and the telemetry message (such as the second message) need to be processed by different terminals, and further the boundary switch can identify the message processing object of the received original message by identifying the message header and send the original message to the message processing object, and the telemetry message (such as the second message) needs to be analyzed by the back end analysis object, so that the boundary switch can send the telemetry message (such as the second message) to the back end analysis object, thereby implementing separation of the original message and the telemetry message (such as the second message) by the boundary switch.

The present invention also provides an alternative embodiment that provides an in-band network telemetry method.

Fig. 2 is a schematic diagram of End-to-End based packet transmission in the related art, as shown in fig. 2, taking a data center network as an example, after an in-band network telemetry Domain INT Domain is configured, each switch inserts INT telemetry data directly into an original packet, generally, the INT telemetry data is selectively inserted behind a 4-layer packet header, as the number of in-band network telemetry Domain INT Domian forwarding devices increases, the number of in-band network telemetry Domain INT telemetry data of the original packet increases, the number of packets also increases, the transmission is greatly affected, and meanwhile, the original packet is not protected from security detection and the like because the original packet is modified in the in-band network telemetry Domain INT Domain, so that erroneous judgment of security devices is prevented, discarding of the packet, and modification of the original packet is not allowed in sensitive services.

Fig. 3 is a schematic diagram of a packet transmission based on Post-card in the related art, as shown in fig. 3, taking a data center network as an example, after an in-band network telemetry Domain INT Domain is configured, after an INT is configured, each switch generates an INT telemetry data from a packet, and then the INT telemetry data is output separately, that is, one stream passes through several switches, so that several INT telemetry messages are generated, and a subsequent analysis system needs to perform a task of preprocessing a plurality of telemetry messages, for example, when the number of the INT telemetry messages is relatively large, a front-end probe or a splitter device needs to be deployed in a back-end analysis system to reduce the load for the subsequent analysis system.

In summary, there are two ways to output the message of INT by in-band network telemetry, one is End-to-End mode, namely, telemetry data is added into the original message to be transmitted, and output is performed at the last switch of one hop, so that the original message is changed, the length of the message is increased, and the transmission and security detection are affected; the other is Post-card mode, namely, the original message is not changed, the telemetering data is sent out from each exchanger independently, and although the mode solves the modification of the original message, each hop exchanger outputs the telemetering data, and the reorganization pressure on a back-end analysis system is high.

The in-band network telemetry scheme provided by the application integrates the advantages of the two schemes, namely discarding the original message changed by End-to-End, discarding the work of Post-Card requiring the back-End system to reorganize the message, greatly reducing the load of a subsequent analysis system and improving the efficiency of INT telemetry.

Fig. 4 is a schematic diagram of an in-band network telemetry method according to an embodiment of the present application, as shown in fig. 4, in an in-band network telemetry Domain INT Domain, an access switch (Source node) performs a replication operation on an original message that needs telemetry, when replication is performed, a Payload portion of a message body in the original message is cut off, only a layer 4 header is reserved, meanwhile, INT data of the Source node (i.e., the access switch) is inserted behind a replication message (e.g., a first telemetry message or a second telemetry message), the original message is not modified, the original message is continuously forwarded in a table according to an original procedure, so that a forwarding path of the replicated message (e.g., the first telemetry message or the second telemetry message) is the same as that of the original message, after the message is sent to a next switch node (tranit), the INT data of the original message is also inserted into a replication Wen Ru first telemetry message or a second telemetry message, after the original message is forwarded to a border switch (e.g., a second telemetry message) is forwarded to a normal network (e.g., a second telemetry node), and an object is analyzed after the replication is completed by the network (e.g., a second telemetry node).

Optionally, the access switch is generally configured with an access control list ACL for the top-frame ToR switch, for identifying a specific traffic (i.e. an original message), and the identification field may be a source destination IP, a protocol number, a TCP/UDP source destination port number, etc.

Optionally, in the process of generating the first remote measurement message, the original message may be subjected to a copying operation, and the load Paylaod of the message body in the copied message (equivalent to the intermediate message) is truncated, so that the message is truncated into a 64/128 byte message.

Alternatively, in-band network telemetry data, i.e., INT data, may be an in-interface, an out-interface, a switch ID, queue information, buffer cache information, etc. of the message.
