Description

Message processing method, device, switch and computer readable storage medium

Technical Field

The present invention relates to the field of data communications, and in particular, to a method and apparatus for processing a packet, a switch, and a computer readable storage medium.

Background

Network measurements are the fundamental means and data sources for network management. Common network measurement modes mainly include active measurement, passive measurement and hybrid measurement. As a hybrid measurement technology, the INT (Inband Network Telemetry, in-band network telemetry) technology is basically a technology for collecting, carrying, arranging, and reporting network conditions by means of traffic on a data plane, and collecting the information without using a special protocol message.

In general, three functional nodes including an INT system and an analyzer are included, where the three functional nodes including an INT Source (Source node), an INT Transit (intermediate node), and an INT Sink (tail node) are sequentially connected to form a telemetry line, after a service packet related to a service flow enters the telemetry line, the INT Source will add metadata corresponding to an INT header and each type of information to be collected in the service packet first, then the INT Transit and the INT Sink insert metadata in sequence, and finally the INT Sink strips out all INT information attached to the service packet and reports the information to the analyzer. The analyzer analyzes INT information related to the service message through the telemetry line and further uses the INT information as display, so that real-time sensing and monitoring of the network operation state are realized.

In general, metadata inserted into each functional node includes port information related to a service message passing through the functional node. However, the three functional nodes have various forms, so that the analyzer cannot analyze the actual meaning of the port information in the INT information independently of the three functional nodes.

Therefore, how to ensure that the analyzer can analyze the port information in the INT information independently is a problem to be solved.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. 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.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.

It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.

The workflow of the INT system of the prior art will be described herein by taking three functional nodes and an analyzer as examples.

Referring to fig. 1, fig. 1 is a schematic view of a scenario of an INT system in the prior art, and the INT system 100 includes: three functional nodes, source node 110, intermediate node 120, tail node 130, and analyzer 140. The sending terminal 150 may communicate with the receiving terminal 160 by sending service messages sequentially through the source node 110, the intermediate node 120, and the tail node 130.

Wherein the analyzer 140 and the source node 110 and the intermediate node 120 can communicate through a dedicated connection network, and the analyzer 140 and the tail node 130 can communicate through a telemet network (telemetry network).

In the process of network maintenance, sometimes, the condition that the forwarding path of the message needs to be verified, for example, in the case of having a multi-hop forwarding path, the verification of whether the message is transmitted according to a planned path, can be realized by using the INT technology. The following is a flow description of the visualization process of the message forwarding path using the INT technology.

The service message consists of a message Header (Packet Header) and carrying Data (Data). When a service Packet (Packet) sent by the sending terminal 150 belongs to a service flow that needs to be monitored by the INT system 100, the following flow exists in the INT system 100:

(1) The source node 110 will first insert an INT header (INT header) into the traffic message that contains the type of information that the traffic message needs to collect via each node. The service message is then inserted through Metadata (Metadata-1) made up of the information that needs to be collected by the source node 110, and the message is then sent to the intermediate node 120.

(2) The intermediate node 120 receives the service message including the INT header sent from the source node, parses the INT header, passes the service message through Metadata (Metadata-2) formed by the information that needs to be collected by the intermediate node 120, and then sends the message to the tail node 130.

(3) The tail node 130 receives the service message including the INT header, parses the INT header, passes the Metadata (Metadata-3) composed of the information to be collected by the tail node 130, and then the tail node 130 fetches and encapsulates all the Metadata (Metadata-1, metadata-2, metadata-3) in the message into an INT message (INT Packet) and sends the INT message to the analyzer 140.

(4) The analyzer 140 synchronizes mapping relations between port information and actual port information in metadata corresponding to each of the three nodes to the source node 110, the intermediate node 120 and the tail node 130.

(5) The analyzer 140 analyzes the port information in the three metadata respectively by using the mapping relation between the port information and the actual port information fed back by the source node 110, the intermediate node 120 and the tail node 130 respectively, so as to obtain the actual port information of the common expression corresponding to the message forwarding path, so as to perform final path display.

In the INT system 100, the source node 110, the intermediate node 120, and the tail node 130 may be switches, and the analyzer 140 may be, but is not limited to, a server, a computer, a personal computer, and the like. In practical applications, the number of intermediate nodes 120 will be generally plural and each intermediate node 120 is processed in the same manner, and the above description is merely for brevity and clarity of describing the flow of the prior art.

In order to verify the forwarding path of the message, the metadata corresponding to each node includes port information of the port through which the service message passes when passing through the node. Since the source node 110, the intermediate node 120, and the tail node 130 are different in their respective types and operation modes, the logical mapping relationship of the port information in the metadata obtained by converting the three nodes may be inconsistent. In this way, it is easy for the port information in different metadata to be identical, but the actual port information corresponding to each of the same port information is different.

Therefore, the analyzer 140 cannot analyze the port information in each metadata independently to obtain the actual meaning of the port information, but the mapping relationship between the port information and the actual port information must be confirmed to the source node 110, the intermediate node 120, and the tail node 130 in the above-mentioned step (4), so that the actual port information corresponding to the port information in all metadata can be successfully analyzed.

Therefore, in the prior art solution, if the source node 110, the intermediate node 120, and the tail node 130 feed back the mapping relationship to the analyzer 140 in time or the data fed back to the analyzer 140 is lost, the analysis of the port information is likely to fail.

Based on the findings of the above technical problems, the inventors have made creative efforts to propose the following technical solutions to solve or improve the above problems. It should be noted that the above prior art solutions have all the drawbacks that the inventors have obtained after practice and careful study, and thus the discovery process of the above problems and the solutions to the problems that the embodiments of the present application hereinafter propose should not be construed as what the inventors have made in the invention creation process to the present application, but should not be construed as what is known to those skilled in the art.

The inventor finds through long-term observation and research that on the basis of not changing the prior art logic, if a unified coding rule is preset, in an INT system, after metadata is inserted into each node through which a service message passes, the node utilizes the unified coding rule to code the actual port information of the port through which the service message passes to obtain port coding information, and the port coding information is used for replacing the port information of the metadata inserted into the service message, so that when the final analyzer analyzes, the port coding information in the metadata can be independently analyzed by utilizing the unified coding rule.

The present invention will be described in detail below by way of examples and with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flow chart of a message processing method provided by an embodiment of the present invention, which is applied to a switch in an INT system, and the method includes the following steps S110 to S130, S150:

s110, under the condition that a message to be monitored is received, telemetry information is acquired.

In this embodiment, the telemetry information may include all data corresponding to multiple types of information to be collected when the message to be monitored passes through the switch. One type of information to be collected is a passing port of a message to be monitored passing through the switch, and the information corresponds to actual port information included in telemetry information. Note that the meaning of port information, i.e., ports, is mentioned in the embodiments of the present invention.

S120, obtaining the chip port information of the corresponding switch according to the actual port information facing the user.

It will be appreciated that the actual port information is user-oriented and user-identifiable, and that the chip port information may be converted by the switch based on the actual port information.

S130, processing the message to be monitored to obtain an initial remote measurement message.

In this embodiment, the initial telemetry message may include the obtained chip port information.

S150, replacing the chip port information in the initial telemetry message with port coding information to obtain the telemetry message to be transmitted.

In this embodiment, the port coding information is obtained by coding the actual port information by using a preset unified coding rule by the switch. The port coding information can be used for an analyzer in the INT system to determine the actual port information corresponding to the message to be monitored passing through the switch.

According to the message processing method provided by the embodiment of the invention, under the condition that the message to be monitored is received, the telemetering information comprising the information of the actual port corresponding to the message to be monitored passing through the switch is obtained. And then processing the message to be monitored to obtain an initial remote measurement message which comprises chip port information obtained by converting the switch based on the actual port information. And then, replacing the chip port information in the initial telemetry message by using port coding information obtained by coding the actual port information based on a preset unified coding rule to obtain the telemetry message to be transmitted. The port coding information can be used for an analyzer in the INT system to determine the actual port information corresponding to the message to be monitored passing through the switch. Thus, when the analyzer analyzes, the unified coding rule can be independently utilized to analyze all port coding information.

Referring to fig. 3, the INT system 200 may include a source node 210, at least one intermediate node 220, a tail node 230, and an analyzer 240, where the source node 210, the at least one intermediate node 220, and the tail node 230 are in communication connection, and the tail node 230 is in communication connection with the analyzer 240.

The source node 210, the intermediate node 220, and the tail node 230 may each be a switch, and the analyzer 240 may be, but is not limited to, a server, a computer, a personal computer, etc.

It should be noted that fig. 3 is only a simple illustration of the INT system 200, and in practical applications, the number of intermediate nodes 220 may be generally plural, and the number of intermediate nodes 220 connected to the source node 210 and the number of intermediate nodes 220 connected to the tail node 230 are all based on practical applications.

The switch in the embodiment of the present invention may be any one of the source node 210, the intermediate node 220, and the tail node 230 in the INT system 200. When the switch is a different node, the processing process of the message to be monitored is partially different. The message to be monitored, the initial remote message and the remote message to be transmitted are only named, and the essence of the message to be monitored, the initial remote message and the remote message to be transmitted are evolved from the five-tuple service message.

The following describes the processing procedure of the message to be monitored in the case that the switch is the source node 210, the switch is the intermediate node 220, and the switch is the tail node 230.

First, in the first case, when the switch is a source node in the INT system, the sub-steps of step S110 described above may include S111 to S113.

S111, when a service message is received and the header part of the service message meets a preset message matching rule, the service message is used as a message to be monitored.

The source node acts as a "relay station" in the network, which may receive service messages sent from different devices or terminals differently. The pre-configured message matching rules may be used to specify traffic flows that need to be monitored. In an alternative example, the pre-configured message matching rules may indicate that traffic messages using the TCP (Transmission Control Protocol ) or UDP (User Datagram Protocol, user datagram protocol) protocol are traffic flows that need to be monitored.

In another alternative example, the pre-configured message matching rules may indicate that the traffic message to be monitored needs to satisfy: the TCP protocol (or UDP protocol) is used and includes one or a combination of a destination IPv4/6 address, a source TCP port number, a destination TCP port number, a source UDP port number, a destination UDP port number.

It should be noted that, the preset message matching rule is set by the user based on the actual monitoring requirement, and is not limited herein. Typically, the header portion of the traffic message may include an IP header, a TCP header, or a UDP header. The pre-configured message matching rule is specific to the header part of the service message, so that when the header part of the service message is matched with the pre-configured message matching rule, the service message can be judged to belong to the service flow needing to be monitored, and the service flow is used as the message to be monitored.

S112, based on a plurality of information types to be collected, which are preconfigured in the INT system, an INT head is generated and is inserted into the message to be monitored.

In the INT system, multiple information types to be collected for the traffic flow to be monitored may be preconfigured in the configuration of the source node. The source node then generates an INT header based on the various information types to be collected and inserts it into the message to be monitored.

S113, based on various information types to be collected, obtaining telemetry information of the message to be monitored passing through the source node.

In this embodiment, one of the multiple types of information to be collected is a via port. In a possible example, the remaining types of information to be collected may include, but are not limited to: path timestamp, path port bandwidth, path port queues, and forwarding delay, among others.

Correspondingly, the telemetry information not only comprises the actual port information corresponding to the passing port, and the actual port information is the inlet port and the outlet port of the message to be monitored passing through the switch. In a possible example, the telemetry information may further include, but is not limited to, a timestamp and an egress timestamp corresponding to the path timestamp, an ingress port bandwidth and an egress port bandwidth corresponding to the path port bandwidth, an ingress port queue and an egress port queue corresponding to the path port queue, and a message forwarding delay corresponding to the forwarding delay.

Meanwhile, when the switch is a source node, please continue to refer to fig. 4, the substeps of the step S130 may include S131 to S132:

s131, the telemetric information is encoded to obtain metadata information.

S132, inserting metadata information into the message to be monitored comprising the INT head, and obtaining an initial remote measurement message.

In this embodiment, the metadata information may include chip port information obtained by converting the source node based on actual port information. For the source node, the corresponding metadata information may further include an ID of the source node.

Because of the difference of the device, in the step S120, the conversion rules or mapping relationships used when the source node, the intermediate node, and the tail node convert the actual port information into the chip port information may be different.

In the second case, when the switch is any intermediate node in the INT system, the substep of step S110 may include S11A to S11B.

S11A, when a service message is received and an INT head exists in the service message, the service message is used as a message to be monitored.

When the INT header exists in the service message received by the intermediate node, the intermediate node takes the service message as a message to be monitored. The message to be monitored at this time may be a remote message to be transmitted sent by a source node in the INT system, or may be a remote message to be transmitted sent by a previous intermediate node.

The intermediate node analyzes the INT header in the message to be monitored to obtain a plurality of information types to be collected, wherein the information types to be collected are contained in the INT header.

S11B, based on various information types to be collected, obtaining telemetry information of the message to be monitored passing through the intermediate node.

And using a plurality of information types to be collected obtained by analyzing the INT head, and obtaining corresponding telemetry information by the intermediate node. Similarly, because one of the multiple information types to be collected is a via port, the telemetry information obtained by the intermediate node also includes the actual port information corresponding to the via port.

Meanwhile, when the switch is an intermediate node, the substep of step S130 may include S13A to S13B:

S13A, encoding the telemetry information to obtain metadata information.

And S13B, inserting metadata information into the message to be monitored to obtain an initial remote measurement message.

In this embodiment, the metadata information may include chip port information obtained by converting the intermediate node based on actual port information. For the intermediate node, the corresponding metadata information of the intermediate node may further include an ID of the intermediate node.

Because of the difference of the self conditions of the devices, the conversion rules or mapping relations used when the source node, the intermediate node and the tail node convert the actual port information into the chip port information are different. Thus, there may be a difference in the conversion rule or the mapping relation used between the chip port information here and the chip port information referred to in step S131 described above.

In a third case, when the switch is a tail node in the INT system, the substep of step S110 described above may include S11a to S11b.

When the INT head exists in the service message received by the tail node, the tail node takes the service message as a message to be monitored. The message to be monitored at this time can be a remote message to be transmitted sent by any intermediate node connected with the tail node in the INT system.

The tail node analyzes the INT header in the message to be monitored to obtain a plurality of information types to be collected, wherein the information types to be collected are contained in the INT header.

S11b, based on various information types to be collected, obtaining telemetry information of the message to be monitored passing through the tail node.

And using a plurality of information types to be collected obtained by analyzing the INT head, and obtaining corresponding telemetry information by the tail node. Similarly, because one of the multiple information types to be collected is a via port, the telemetry information obtained by the tail node also comprises the actual port information corresponding to the via port.

Meanwhile, when the switch is a tail node, the substep of the step S130 may include S13a to S13b:

and S13a, encoding the telemetry information to obtain metadata information.

In this embodiment, the metadata information may include chip port information obtained by converting the tail node based on actual port information. For the tail node, the corresponding metadata information of the tail node can also comprise an ID (identity) of the tail node. The chip port information herein may be different from the chip port information referred to in the above steps S131 and S13A in terms of conversion rule or mapping relationship used for each.

The above description describes the process of obtaining the initial remote measurement message by using the message to be monitored in each of the three cases.

Before the step S150, the source node, the intermediate node, and the tail node all need to obtain the port coding information. The source node, the intermediate node and the tail node can all obtain the respective port coding information in the following two modes.

Two ways of obtaining port coding information will be described below using a source node as an example. When the message to be monitored passes through the source node, the transmission ports which the message to be monitored can relate to pass through the source node comprise a transmission port in the input direction and a transmission port in the output direction. Accordingly, the actual port information may include: the actual ingress port information for ingress direction and the actual egress port information for egress direction.

The first way is that the source node performs real-time processing, and before the step S150, the method further includes the steps of:

and S140, coding the actual inlet port information and the actual outlet port information by utilizing a unified coding rule to obtain coded inlet port metadata and coded outlet port metadata.

In this embodiment, the port coding information may include the above-described coded ingress port metadata and coded egress port metadata.

The encoded ingress port metadata and the encoded egress port metadata both belong to the encoded port metadata, and the data structure of the encoded port metadata in the message is described below.

The metadata information comprises a plurality of metadata, each metadata occupies 4 bytes, the metadata is divided into four parts, and each part occupies 8bits. And the encoded ingress port metadata and the encoded egress port metadata each occupy 4 bytes.

The data structure of the encoded port metadata, namely the encoded ingress port metadata and the encoded egress port metadata, is shown in fig. 4, and the encoded port metadata comprises four fields, namely a port form, a member number, a slot number and a port number, and each field occupies 8bits.

The port morphology may represent a data forwarding rate of the corresponding transmission port. The corresponding relation between the coding value of the port morphology and the corresponding actual value can be obtained by searching a preset port morphology coding rule table. In special cases, if the transmission port is a link aggregation port, the coding of the port morphology may start from 128 (i.e. corresponding hexadecimal representation 80).

The member number may represent the number of the switch in the network architecture, for example, in a stacking environment, when a plurality of switches are stacked to form a stacking unit, a message needs to pass through the stacking unit, and enter from a transmission port of one switch and then exit from a transmission port of another switch. Thus, in a stacked environment, the member number may indicate to which switch in the stacked unit the corresponding transport port belongs. The actual value of the member number may be generally taken as its encoded value; in a special case, if the transmission port is a link aggregation port, the corresponding code value of the member number is 0.

The slot number may represent a slot position corresponding to the board card to which the corresponding transmission port belongs. The actual value of the slot number can be generally taken as the code value thereof; in a special case, if the transmission port is a link aggregation port, the corresponding coding value of the slot number is 0.

The port number may represent the location of the corresponding transport port on the board. The actual value of the port number may be generally taken as its encoded value; in a special case, if the transmission port is a link aggregation port, the corresponding code value of the port number may be a link aggregation number.

In this embodiment, the preset port morphology coding rule table may represent a mapping relationship between an actual value and a coded value of each port morphology.

In an alternative example, the preset port morphology coding rule table may be as follows:

actual value of port morphology	Coded value
		10M	0
100M	1
		1000M	2

In the table, link-aggregation indicates a Link aggregation port. The example is only one example, and in practical application, the size of each port morphology actual value in the preset port morphology coding rule table depends on the port type and the data forwarding rate of each transmission port of each switch in the INT system.

Taking an example that one piece of actual port information in the telemetry information is 100ge/1/0/1, in combination with fig. 5, the coded port metadata corresponding to the telemetry information obtained by using the unified coding rule may be: 0x06010001.

For the actual port information of 100ge/1/0/1, it is assumed that when its corresponding transmission port belongs to the source node, the intermediate node, and the tail node, respectively, the corresponding local port metadata may be 0x108, 0x206, and 0x243, respectively. Then in step S140 above, the source node would replace 0x108 with 0x06010001, the intermediate node would replace 0x206 with 0x06010001, and the tail node would replace 0x243 with 0x06010001.

It should be noted that the foregoing examples are illustrative for easy understanding and are not intended to be limiting.

The second way is that the source node stores a global port mapping table in advance, and the global port mapping table may include a mapping relationship between actual port information corresponding to each transmission port of the switch and the encoded port metadata. The coded port metadata is obtained by coding the actual port information of the corresponding transmission port by utilizing a unified coding rule. The process of obtaining the encoded port metadata may refer to the description of the first mode, which is not repeated herein.

At this time, before the step S150, the method further includes the steps of:

s140', the coded input port metadata corresponding to the actual input port information and the coded output port metadata corresponding to the actual output port information are obtained from the global port mapping table.

In this embodiment, the port coding information may include coded ingress port metadata corresponding to the ingress direction and coded egress port metadata corresponding to the egress direction.

In an alternative embodiment, when the switch is a tail node in the INT system, after step S150, the method further includes steps S160 to S170:

s160, acquiring INT information from a telemetry message to be transmitted.

The tail node may receive a remote measurement message to be transmitted sent by the last intermediate node on the forwarding path of the service message, and correspondingly, the INT information may include metadata information corresponding to the source node, metadata information corresponding to each intermediate node, and metadata information corresponding to the tail node, which are collected during the transmission process of the service message.

S170, the INT information is sent to an analyzer, so that the analyzer analyzes the actual port information corresponding to each node of the INT system, through which the message to be monitored passes, from the INT information based on the unified coding rule.

Referring to fig. 3, the tail node may encapsulate the INT information into an INT message and send the INT message to the analyzer, and after the analyzer receives the INT message, the analyzer analyzes the INT message to obtain relevant information of the service message in the transmission process of the INT system.

For the port coding information in the metadata information corresponding to the source node, the intermediate node and the tail node, the analyzer can analyze the port coding information of each node by utilizing a unified coding rule to obtain the actual input port information and the actual output port information of the output direction of the service message in the respective corresponding input directions when the service message passes through the source node, the intermediate node and the tail node.

Meanwhile, the INT message not only can comprise INT information, but also can comprise source IP address, destination IP address, protocol number, source port, destination port and other information corresponding to the service message, so that the analyzer can conveniently analyze the relevant information in the transmission process of the service message from the INT message, and verify the information such as the source IP address, destination IP address, protocol number, source port, destination port and the like corresponding to the service message body.

It should be noted that, in the above method embodiment, the execution sequence of each step is not limited by the drawing, and the execution sequence of each step is based on the actual application situation.

Compared with the prior art, the embodiment of the invention has the following beneficial effects:

the analyzer is ensured to independently analyze the port coding information in the metadata by utilizing the unified coding rule to obtain the actual port information of each port through which the message to be monitored passes in the INT system;

And an analyzer is not required to communicate with the source node and the intermediate node, so that networking cost and communication cost are saved. Meanwhile, the time for analyzing the data by the analyzer is also improved, and the operation and maintenance efficiency of the network is improved.
