This application claims priority to chinese patent application 201911024904.7 entitled "network quality measurement method, apparatus, device, and medium for bundled links" filed on 25/10/2019, the entire contents of which are incorporated herein by reference.

Technical Field

Background

Currently, the quality between two points in a network is mainly measured by means of an Internet Packet explorer (ping) command. Because the ping command cannot control the forwarding path of the data packet in the network, when a binding link (sometimes also called a binding group) exists between two points to be tested, it cannot be determined which member link the measured quality index is, and the difference between the quality indexes of different member links in the binding group, such as time delay, is often large due to different transmission paths, different load conditions, and the like, so that the quality index result obtained by ping measurement cannot represent the quality of all the member links, and the measurement accuracy of the network transmission quality of the binding link is low.

Detailed Description

Features and exemplary embodiments of various aspects of the present invention will be described in detail below, and in order to make objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

The embodiment of the invention provides a network performance test scheme aiming at a binding link, which can measure the network performance of the binding link on the basis of the existing network performance measurement protocol.

The existing network performance Measurement Protocol, such as Two-way Active Measurement Protocol (TWAMP Protocol), (Two-way Active Measurement Protocol Light, TWAMP Light) lightweight Two-way Active Measurement Protocol, One-way Active Measurement Protocol (OWAMP Protocol), or Simple Two-way Active Measurement Protocol (STAMP Protocol), is processed and responded by dedicated hardware directly on the interface board, and does not use the CPU of the main control board to process, and the Measurement accuracy is much higher than ping. However, the forwarding path of the data packet in the network cannot be controlled, when a bundled link exists between two points, the existing network performance measurement protocol only measures the quality index of one member link, and because the quality indexes such as time delay of different member links are different and sometimes different even very much, the measurement result of the existing network performance measurement protocol also cannot represent the quality of the whole bundled link, therefore, a technical scheme capable of measuring the quality index of each specific member link in the bundled link is required.

To facilitate understanding of the bundled links, member links, and the relationship between the two. Fig. 1 is a schematic structural diagram of an exemplary bundled link according to an embodiment of the present invention. If N information transmission paths exist between two communication nodes in the communication network and the information transmission paths logically form one transmission path, it is indicated that a binding link exists between the two communication nodes, and the binding link includes N member links. The N information transmission paths respectively correspond to N member links. N is an integer of 2 or more.

As shown in fig. 1, the beijing node and the shanghai node serve as two communication nodes in a communication network. When information is transmitted between the Shanghai node and the Beijing node, three different information transmission paths are provided. Respectively as follows:

a first transmission path, beijing-tianjin-jonan-nanjing-suzhou-shanghai;

a second transmission path, Beijing, Heshui, Kaifeng, Hefei, Huzhou, Shanghai;

the third transmission path, Beijing-Shijiazhu-Zhengzhou-Wuhan-Nanchang-Hangzhou-Shanghai.

Correspondingly, three member links exist between the Shanghai node and the Beijing node, and respectively correspond to the first transmission path, the second transmission path and the third transmission path. The three member links form a binding link between the Beijing node and the Shanghai node.

Because the Beijing node and the Shanghai node can be in two-way communication, any one of the Beijing node and the Shanghai node can be used as a first node, and the other one of the Beijing node and the Shanghai node can be used as a second node.

Further, for a bundled link between the first node and the second node, the bundled link includes N member links. Each member link corresponds to a physical port on the first node, and then N physical ports of the N member links on the first node form a logical port, for example, a trunk (trunk) port, and at this time, the logical port may be a port of the binding link on the first node. Similarly, the N physical ports of the N member links on the second node form a logical port, such as a trunk (trunk) port, and the logical port may be a port of the binding link on the second node.

For better understanding of the present invention, a network quality measurement method, apparatus, device and medium for bundled links according to embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be noted that these embodiments are not intended to limit the scope of the present disclosure.

Fig. 2 is a schematic flowchart of a network quality measurement method for a bonded link according to an embodiment of the present invention. As shown in fig. 2, the method 200 for measuring network quality for bundled links in the present embodiment may include S210 to S250:

s210, establishing a test session of a plurality of member links of the binding link. If a testing session is established in a member link, it indicates that a connection required for network transmission quality detection on the member link is maintained between the first node and the second node. It should be noted that, the following steps of performing network transmission quality detection on each member link need to be established on the basis of the test session established by the member link.

In the process of establishing the test sessions of the plurality of member links, if the bundled link includes N member links, in S210, respective test sessions may be established for at least some of the member links in the bundled link. Preferably, a respective test session may be established for each member link of the bundled link at the same time.

In some embodiments, S210 may be embodied as S211 to S215.

S211, the first node receives a test command of the binding link. Wherein the test command of the bundled link is used for instructing the first node to start executing the test method of the bundled link.

S212, the first node detects whether the port of the first node is a binding link port according to the test command of the binding link. For example, the first node may determine whether the port of the first node is a bundled link port according to the configuration parameter of the port of the first node. If the result of the detection is yes, the process proceeds to S213. If the detection result is negative, the method can be converted into a common test method, or the test can be directly stopped, and a prompt message of port configuration error is generated. The common test method is established on the basis of the original network performance measurement protocol, and cannot measure the designated member link.

S213, if the port is the binding link port, the first node sends a member link test request to the second node. Wherein the member link test request may be an extension enhancement based on an already deployed network performance measurement protocol between the first node and the second node. The network performance measurement protocol deployed between the first node and the second node may be a TWAMP protocol, a TWAMP Light protocol, an OWAMP protocol, or a STAMP protocol, and the like, which is not limited in particular.

For example, fig. 3 is a schematic diagram of a format structure of Request-TW-Session information of a TWAMP protocol according to an embodiment of the present invention. Taking the example that the TWAMP protocol is deployed between the first node and the second node, the member link test Request is a command type defined in the two-way Session Request (Request-TW-Session) information of the TWAMP protocol, as shown in fig. 3, a command number (command number) field of the Request-TW-Session information indicates the command type. For example, Request-TW-Session information with a command number field of 11 may be defined as a member link test Request. It should be noted that, an undefined value of The command number field may also be defined by The Internet Assigned Numbers Authority (IANA) as The member link test request, which is not limited in particular. At present, the value of 11-255 in the command number field of the Request-TW-Session information defines the corresponding command type. That is, a value may be selected from the range of values 11-255, and the corresponding command type may be defined as the member link test request.

Further, with continued reference to fig. 3, the Request-TW-Session information in fig. 3 further includes a null (Must Be Zero, MBZ) field, an Internet Protocol (IP) version number (IPVN) field, a Sender profile (Conf-Sender) field, a Receiver profile (Conf-Receiver) field, a Sender Port (Sender Port) field, a Receiver Port (timer Port) field, a Sender Address (Sender Address) field, a Receiver Address (Receiver Address) field, a Session identification information (SID) field, a Padding Length (Padding Length) field, a Session initiation Time (Start) field, a latency threshold (out) field, a Hash-based Message Authentication Code (HMAC) field.

It should be noted that the format of the Request-TW-Session information in this example is only one possible specific implementation, and the specific format may be adjusted according to specific scenarios and requirements, which is not limited herein.

S214, the second node receives the member link test request, determines that the plurality of member links support member link test and the member link test request is normal based on the member link test request, and sends a response success message of the member link test request to the first node.

Before executing S214, S210 may further include a step of determining whether the plurality of member links support the member link test based on the member link test request, and determining whether the member link test request is correct, corresponding to S214. Whether the plurality of member links support the member link test can be judged by detecting whether the port of the second node supports the member link test. And if the port of the second node supports the member link test, proving that all the member links between the first node and the second node support the member link test. Wherein, whether the member link test request is correct can be determined by checking whether the configuration parameters of the member link test request have errors. If the parameters of the member link test request have errors, the member link test request is proved to be wrong; and if the parameters of the member link test request have no errors, the member link test request is proved to be correct.

Correspondingly, if the port of the second node does not support the member link test, the second node sends a second response failure message which represents that the port of the second node does not support the member link test to the first node.

And if the parameters of the member link test request have errors, the second node sends a first response failure message representing the error of the member link test request to the first node. Specifically, different parameters in the member link test request correspond to different error codes, and if a certain parameter of the member link test request is wrong, the error code corresponding to the parameter is set to the first response failure message.

In some embodiments, the response success message, the first response failure message, and the second response failure message may be implemented on the basis of a network performance measurement protocol.

Fig. 4 is a schematic diagram of a format structure of Accept-Session (Accept-Session) information of an exemplary TWAMP protocol according to an embodiment of the present invention. Taking the example that the TWAMP protocol is deployed between the first node and the second node, the response success message, the first response failure message, and the second response failure message may be three different types of response message types defined in the Accept-Session information. As shown in fig. 4, the Accept field of the Accept-Session information indicates the type of the response message. For example, if the Accept field is 0, the Accept-Session information corresponds to the response success message. If the Accept field is 3, the Accept-Session information corresponds to the second response failure message. Further, the first response failure message may correspond to a plurality of values of the Accept field, considering that the first response failure message may correspond to different error types. Different values may correspond to different parameter errors.

In addition, with continued reference to fig. 4, the Accept-Session information in fig. 4 further includes a null (MBZ) field, a Port (Port) field, a Session identification information (SID) field, and a Hash-based Message Authentication Code (HMAC) field.

It should be noted that the format of the Accept-Session information in this example is only one feasible specific implementation, and the specific format may be adjusted according to specific scenarios and requirements, which is not limited herein.

S215, the first node receives the response success message of the member link test request, and responds to the response success message of the member link test request to establish the test session of the plurality of member links. Illustratively, after receiving the response success message of the member link test request, the first node sends a test Session Start (Start-Session) request to the second node, and after the second node returns the information confirming the Start of the test Session (Start-Ack), the test sessions of the plurality of member links are established.

In some embodiments, in order to ensure the normal execution of the network quality test flow of each member link, after receiving the response success message of the member link test request, the first port of each member link on the first node and the second port of each member link on the second node need to be confirmed. The specific confirmation method may include: and confirming by using the interactive negotiation process of each member link, or confirming according to the configuration information. The above confirmation process will be specifically described below by two specific examples.

In the first embodiment, for example, the first node and the second node communicate based on TWAMP protocol, before performing the network quality test, an interactive negotiation process for each member link may be further performed. In the interactive negotiation process, both the first node and the second node need to determine the first port identification information and the second port identification of each member link. Wherein the first port is a physical port of the first node and the second port is a physical port of the second node. The first port identification information can uniquely identify each port of the first node, and the second port identification information can uniquely identify each port of the second node. Illustratively, the first port identification information and the second port identification information may each be an Identity Document (ID) of the port.

For the first node and the second node, both the nodes can determine the port identifier of each member link of the nodes, and the nodes can also determine the port identifier information of each member link of the other node according to the information sent by the other node. Specifically, the first node may determine first port identification information of each member link of the first node, and determine second port identification information of each member link according to a response success message of the member link session request sent by the second node. The second node may obtain the first port identification information of each member link from the member link session request, and may determine the second port identification information of each member link of the second node.

In one embodiment, the specific implementation of the interactive negotiation process includes the following steps:

the first step, the first node determines the first port identification information of each member link of the first node. And the first node sends a member link session request to the second node through each member link. Wherein, the member link session request carries the first port identification information of each member link.

In one example, fig. 5 is a schematic diagram illustrating a format structure of an exemplary member link session request according to an embodiment of the present invention. The Member link Session Request in fig. 5 is specifically implemented as a Request-Member-Session message. As shown in fig. 5, the Request-Member-Session Message may include a Member-link Session Request sequence number (RMS command) field, a null (MBZ) field, a Member-link ID (MY Member ID) field, a Member-link ID (content) (MY Member ID (Cont)) field, a Member-link ID (Your Member ID) field, a Member-link ID (content) (Your Member ID (Cont)) field, a Session identification information (SID) field, and a Hash-based Message Authentication Code (HMAC) field.

Wherein the RMS command field may represent a Request-Member-Session message with a predefined value. Wherein the predefined values may be defined upon normalization. The MBZ field is a reserved field and needs to be set to 0. The Your Member ID field may be written with the second port identification information of the Member link, and if the second port identification information is not preconfigured, the field is set to 0, and if the second port identification information is preconfigured, the field is written with a specific configuration value. The MY Member ID field may write first port identification information of the Member link.

It should be noted that the format of the Request-Member-Session message in this example is only one possible specific implementation, and the specific format may be adjusted according to specific scenarios and requirements, which is not limited herein.

And a second step, the second node receives a member link conversation request sent by the first node through each member link, and acquires the first port identification information of each member link from the member link conversation request. And the second node determines second port identification information of each member link of the second node. Illustratively, if the specific format of the Member link Session Request is as shown in fig. 5, the first port identification information of the Member link may be obtained from the MY Member ID field of the Request-Member-Session message shown in fig. 5. Specifically, if the bundled link includes member link a, member link B, and member link C. After receiving the Request-Member-Session message through the Member link B, the second node may obtain the identification information of the physical port of the Member link B on the first node from the MY Member ID field.

And step three, the second node generates a response success message of the member link session request, wherein the response success message of the member link session request carries the second port identification information.

In some embodiments, the second node returns a response message after receiving a successful link session request. The response success message described above is only one type of response message. In addition to the response success message, the response message may also be a response failure message.

Specifically, if the session identification information that the second node can obtain from the member link session request is wrong, a first response failure message is returned. Illustratively, the session identification information may be obtained from the SID field of the member link session request shown in fig. 5.

Specifically, if the second node can obtain the second port identification information of each member link from the member link session request and determine that the obtained second port identification information is wrong, a second response failure message of the member link session request is generated. Specifically, if the second port identification information obtained from the member link session request is inconsistent with the second port identification information preconfigured in the local terminal, or the second port identification information obtained from the member link session request is not 0, it is determined that the second port identification information is incorrect.

In an example, fig. 6 is a schematic structural diagram illustrating a format of an exemplary response message of a member link session request according to an embodiment of the present invention. The response message of the Member link Session request is specifically implemented as an Accept-Member-Session message. The specific format of the member link session request shown in fig. 5 is similar to that of the response message of the member link session request shown in fig. 6, except that fig. 6 includes a response status (Accept) field. When the state value of the Accept field is 0, the response message is specifically a response success message. When the state value of the Accept field is 1, the response message is specifically a first response failure message. When the state value of the Accept field is 2, the response message is specifically a second response failure message.

It is emphasized that the MY Member ID field of the Accept-Member-Session message fills out the second port identification information of the Member link. And the first port identification information of the Member link is filled in the Your number ID field of the Accept-number-Session message. The first port identification information is obtained from the MY Member ID field of the Member link session request shown in fig. 5.

In addition, it should be further noted that the format of the Accept-Member-Session message in this example is only one possible specific implementation, and the specific format may be adjusted according to specific scenarios and requirements, which is not limited herein.

And fourthly, the second node sends a response success message of the member link conversation request to the first node through each member link. That is, a response success message of the session request of the member link a needs to be transmitted to the first node through the member link a.

And step five, the first node receives a response success message of the member link session request sent by the second node, and acquires the second port identification information of each member link from the response success message of the member link session request. Illustratively, the second port identification information may be acquired from the MY Member ID field of the response success message of the Member link session request shown in fig. 6.

In some embodiments, the first node may further obtain the first port identification information of each member link from a response success message of the member link session request. The first node judges whether the received first port identification information is consistent with the first port identification information of the local terminal, and if so, returns a confirmation message of a response success message to the second node. The first node enters an interactive negotiation completion state after sending the confirmation message, and the second node enters an interactive negotiation completion state after receiving the confirmation message. After the first node and the second node both enter the interactive negotiation completion state, the subsequent network quality measurement process can be continuously executed. Optionally, if the first node determines that the received first port identification information is inconsistent with the first port identification information of the local terminal, the response success message is ignored.

In an example, fig. 7 is a schematic structural diagram illustrating a format of an acknowledgement message of a response success message of an exemplary member link session request according to an embodiment of the present invention. The acknowledgement message of the response success message of the Member link Session request is specifically implemented as an Ack-Member-Session message. The specific format of the acknowledgement message of the response success message of the Member link Session request shown in fig. 7 is similar to that of the Member link Session request shown in fig. 5, except that fig. 7 includes a Member link acknowledgement message sequence number (AMS command) field. The AMS command field may represent the Ack-Member-Session message with a predefined value. Wherein the predefined values may be defined upon normalization.

It is emphasized that the MY Member ID field of the Ack-Member-Session message fills out the second port identification information of the Member links of the first node. The MY Member ID field of the Ack-Member-Session message is consistent with the MY Member ID field of the Request-Member-Session message shown in fig. 5. The yourmember ID field of the Ack-Member-Session message fills in the second port identification information of the Member link acquired from the response success message shown in fig. 6.

In a second embodiment, for example, the first node and the second node communicate based on the TWAMP Light protocol, and the first node and the second node may confirm the first port identification information and the second port identification information of each member link based on the data channel before performing the network quality test because the TWAMP Light protocol has no corresponding control channel.

Specifically, the first node and the second node may receive configuration information of each member link, where the configuration information includes first port identification information and second port identification information of the member link. S220, on the basis of the test session of each member link, the first node sends a session sender test message to the second node through the member link.

In some embodiments of the invention, the type of the session sender test message may be related to a network performance testing protocol deployed between the first node and the second node. If the TWAMP protocol is deployed between the first node and the second node, the Session-Sender test message may be obtained by improving the original Session-Sender test (Session-Sender test) message. For example, the identity of the corresponding member link may be specifically added to the session sender test message. For example, if the bundled link includes N member links, S220 may generate N session sender test messages, where N data packets carry the identity identifiers of the N member links, and are sent to the second node through the respective corresponding member links.

For the ethernet member link, the identity may be a hardware Address (MAC Address) of the ethernet member link, or may be a serial number of the member link, such as an interface index. For POS (Packet Over SONET/SDH, which is a Packet data transmission technology applied in metropolitan area networks and wide area networks), the identity of the member link may be the number of the member link, such as interface index.

In the process of improving the original Session-Sender test packet to obtain the test message of the Session Sender, the test message of the Session Sender can be generated by adding a new field or changing the original field on the basis of the original Session-Sender test packet. In particular, the following section introduces a specific possible implementation of the above two session sender test messages by four examples.

As an example, fig. 8 is a schematic diagram illustrating a format structure of an exemplary session sender test message according to an embodiment of the present invention. For the Session-Sender test packet in the non-authentication mode, a Member link Identity identifier (Member ID) field may be added on the basis of the original Session-Sender test packet, and the Identity of the Member link is added into the Member ID field. As shown in fig. 8, a Member ID field may be added between an Error Estimate (Error Estimate) field and a Packet Padding (Packet Padding) field. The Member ID field of the Session-Sender test packet records the identity of the Member link where the Sender (i.e., the first node, Sender) transmits the Session Sender test message. It should be noted that the packet format in this example is only one possible specific implementation, and the specific format may be adjusted, which is not limited herein. In addition, the Session-Sender test packet shown in fig. 8 may further have a Sequence Number (Sequence Number) field, a timestamp (timestamp) field, and a MY Member ID (Cont) field.

As another example, fig. 9 is a schematic diagram illustrating a format structure of another exemplary session sender test message according to an embodiment of the present invention. Fig. 9 is also a Session-Sender test packet in a non-authentication mode, and is different from the Session-Sender test packet in the non-authentication mode shown in fig. 8 in that the Session-Sender test packet in the non-authentication mode shown in fig. 9 is added with a My number ID field and a Your number ID field on the basis of the original Session-Sender test packet. The My Member ID field is filled with the first port identification information of the Member link confirmed by the first node itself, and the Your Member ID field is filled with the second port identification information of the Member link obtained through the negotiation process. It should be noted that the packet format in this example is only one possible specific implementation, and the specific format may be adjusted, which is not limited herein.

As another example, fig. 10 is a schematic diagram illustrating a format structure of another exemplary session sender test message according to an embodiment of the present invention. For the Session-Sender test packet in the authentication and encryption mode, as shown in fig. 10, based on the original Session-Sender test packet, 6 bytes in the MBZ field may be used as the Member ID field, and the identity of the Member link is added to the Member ID field. It should be noted that the packet format in this example is only one possible specific implementation, and the specific format may be adjusted, which is not limited herein.

As another example, fig. 11 is a schematic diagram illustrating a format structure of a test message of a session sender according to another example provided in the embodiment of the present invention. Fig. 11 is also a Session-Sender test packet of an authentication and encryption mode, and is different from the Session-Sender test packet of the authentication and encryption mode shown in fig. 10 in that the Session-Sender test packet shown in fig. 11 represents a My number ID field, a My number ID (Cont) field, a younumber ID field, and a younumber ID (Cont) field with 12 bytes in an MBZ field on the basis of the original Session-Sender test packet. The My Member ID field is filled with the first port identification information of the Member link confirmed by the first node itself, and the Your Member ID field is filled with the second port identification information of the Member link obtained through the negotiation process. It should be noted that the packet format in this example is only one possible specific implementation, and the specific format may be adjusted, which is not limited herein.

And S230, the second node receives the session sender test message and generates a session reflector test message according to the session sender test message.

In some embodiments of the invention the same as the session sender test message is that the type of session reflector test message is also related to the network performance test protocol deployed between the first node and the second node. If the TWAMP protocol is deployed between the first node and the second node, the Session-Reflector test message may be obtained by modifying an original Session-Reflector test (Session-Reflector) packet. For example, the identity of the corresponding member link may be specifically added to the session reflector test message.

In the process of improving the original Session-Reflector test packet to obtain the Session-sender test message, the Session-Reflector test message may be obtained by adding a new field or changing the original field on the basis of the original Session-Reflector test packet. In particular, the following section describes, by way of four examples, a specific possible implementation of the two session reflector test messages described above.

As an example, fig. 12 is a schematic diagram illustrating a format structure of an exemplary session reflector test message according to an embodiment of the present invention. For the Session-Reflector test packet in the non-authentication mode, a Sender Member link Identity identifier (Sender Member Identity, Sender Member ID) Sender Member ID field may be added on the basis of the original Session-Reflector test packet, and the value of the Member ID field in the Session-Reflector test packet received from the corresponding Member link is added into the Sender Member ID field. As shown in fig. 12, a Sender Member ID field may Be added between a null (Must Be Zero, MBZ) field and a Sender Time-To-Live (Sender TTL) field. The number ID field of the Session-Reflector test data packet is the same as the number ID field of the Session-Sender test data packet received from the corresponding Member link. Specifically, the number ID field of the Session-Sender test packet received from the corresponding Member link may be copied by the second node, and the copied number ID field may be used as the Sender number ID field of the Session-Reflector test packet. The Member ID field of the Session-Reflector test packet records the identity of the Reflector (i.e., the second node, Reflector) edited for the Member link transmitting the Session Reflector test message.

In addition, with continued reference to fig. 12, a Member ID field may also be added on the basis of the original Session-Reflector test packet. For specific implementation of the Member ID field, reference may be made to relevant contents of the foregoing embodiments, and details are not described here. It should be noted that the packet format in this example is only one possible specific implementation, and the specific format may be adjusted, which is not limited herein.

As another example, fig. 13 is a schematic diagram illustrating a format structure of another exemplary session reflector test message according to an embodiment of the present invention. Fig. 13 is also a Session-Reflector test packet in the non-authentication mode, and as can be seen from a comparison between fig. 12 and fig. 13, the structures of the Session-Reflector test packet shown in fig. 12 and the Session-Reflector test packet shown in fig. 13 are substantially similar. The difference lies in that: for the number ID field of FIG. 12, the same location of FIG. 13 is the MY number ID field; for the number ID (Cont) field of FIG. 12, the same location of FIG. 13 is the MY number ID (Cont) field; for the Sender number ID field of fig. 12, the same location of fig. 13 is the Your number ID field; for the Sender number ID (Cont) field of FIG. 12, the same location of FIG. 13 is the Your number ID (Cont) field. The processing manner of the MY Member ID field and the Your Member ID field is the same as that of the Member ID and Sender Member ID fields shown in fig. 12, and will not be described herein again. It is emphasized that the MY Member ID field is written to the second port identification information of the Member link and the Your Member ID field is written to the first port identification information of the Member link.

As another example, fig. 14 is a schematic diagram illustrating a format structure of another exemplary session reflector test message according to an embodiment of the present invention. For the Session-Reflector test packet in the authentication and encryption mode, as shown in fig. 14, on the basis of the original Session-Reflector test packet, one of the two MBZ fields may be used as a Sender Member ID field, and the value of the Member ID field in the Session-Reflector test packet received from the corresponding Member link may be added to the Sender Member ID field. Alternatively, the other of the two MBZ fields may also be the Member ID field. As shown in fig. 14, the Session-Reflector test packet further includes: a Sequence Number (Sequence Number) field, a Timestamp (Timestamp) field, an Error Estimate (Error Estimate) field, a receiver Timestamp (Receive Timestamp) field, a Sender Sequence Number (Sender Sequence Number) field, a Sender Timestamp (Sender Timestamp) field, a Sender Error Estimate (Sender Error Estimate) field, a Sender time-to-live (Sender TTL) field, a Hash Message Authentication Code (HMAC) field. It should be noted that the packet format in this example is only one possible specific implementation, and the specific format may be adjusted, which is not limited herein.

As another example, fig. 15 is a schematic diagram illustrating a format structure of another exemplary session reflector test message according to an embodiment of the present invention. Fig. 15 is also a Session-Reflector test packet in an authentication and encryption mode, and as can be seen from a comparison between fig. 14 and fig. 15, the structures of the Session-Reflector test packet shown in fig. 14 and the Session-Reflector test packet shown in fig. 15 are substantially similar. The difference lies in that: for the Member ID field of FIG. 14, the same location of FIG. 15 is the MY Member ID field; for the number ID (Cont) field of FIG. 14, the same location of FIG. 15 is the MY number ID (Cont) field; for the Sender number ID field of fig. 14, the same location of fig. 15 is the Your number ID field; for the Sender number ID (Cont) field of FIG. 14, the same location of FIG. 15 is the Your number ID (Cont) field. The processing manner of the MY Member ID field and the Your Member ID field is the same as that of the Member ID and Sender Member ID fields shown in fig. 14, and will not be described herein again. It is emphasized that the MY Member ID field is written to the second port identification information of the Member link and the Your Member ID field is written to the first port identification information of the Member link.

In some embodiments, after receiving the Session Sender test message, the second node obtains the My number ID field and the yourmember ID field from the Session-Sender test packet shown in fig. 8-11. And the second node confirms whether the acquired My number ID field and the obtained Your number ID field are correct or not. Specifically, the second node determines whether the acquired My number ID field is consistent with the second port identification information of the Member link obtained through the negotiation process, and determines whether the acquired Your number ID field is consistent with the second port identification information of the Member link at the local end. If both are consistent, a session reflector test message is returned.

S240, the second node sends a session reflector test message to the first node through each member link. It should be noted that, if the second node receives the session sender test message sent by the first node through the ith member link, the second node still needs to return the session reflector test message to the first node through the same member link, that is, the ith member link.

And S250, the first node receives the session reflector test message and detects the network transmission quality information of each member link according to the session reflector test message of each member link. Wherein the network transmission quality information includes quality information capable of reflecting the performance of the IP network. Illustratively, the network transmission quality information may include one or more of latency, jitter, and packet loss rate. The time delay of the member link refers to the delay time of data transmission in the member link, and includes one-way time delay and round-trip time delay. The jitter of the member link, also referred to as IP latency variation, refers to the amount of variation in the successive arrival times of data packets as they travel from the first node to the second node over the member link. The packet loss rate refers to the time interval within which the first node and the second node pass through the member link

In some embodiments, the delay information may be divided into one-way delay information and two-way delay information. For ease of understanding, the measurement process is illustrated with a two-way time delay.

Illustratively, if the network transmission quality information includes two-way delay information, at the time of executing S220, that is, when the first node sends the session sender test message, the session sender test message is time-stamped with T1. When the session-sender test message arrives at the second node, the session-sender test message is time-stamped with a time stamp T2. In performing S230, the session reflector test message generated by the second node based on the session sender test message carries time stamps T1 and T2. In performing S240, i.e. sending a session reflector test message to the second node, time stamping T3 on the session reflector test message; and time stamp T4 is stamped on the session reflector test message when it is received by the first node.

Furthermore, upon receiving the session reflector test message, to ensure measurement accuracy, the session reflector test message may first be checked for matching with its transmitting member link. And if the member links are matched with each other, detecting the network transmission quality information of the member links according to the session reflector test message of each member link. If not, the session reflector test message is discarded, and the message can be optionally alarmed. Specifically, the method for determining whether the session reflector test message matches with the Member link transmitted by the session reflector test message may be to determine whether the Sender Member ID of the session reflector test message is consistent with the identity of the transmitting Member link.

It is emphasized that in S250 session reflector test messages for a plurality of member links may be received. The network transmission quality of each member link can be calculated separately according to the session reflector test message of the member link.

In some embodiments of the present invention, after determining the network transmission quality information of the member links of each member link, in order to ensure the transmission efficiency of the information to be transmitted, the method 200 further includes S260 and S270.

And S260, determining a target link matched with the flow to be transmitted in the plurality of member links according to the service quality requirement information of the flow to be transmitted and the network transmission quality information of the plurality of member links. The qos requirement information of the traffic to be transmitted may record a transmission quality requirement of the traffic to be transmitted on the transmission link. For example, the qos requirement information may include information about whether it is sensitive to delay, whether it is sensitive to jitter, and a requirement for packet loss rate.

In S260, a target link may be determined according to the qos requirement information of the traffic to be transmitted and the network transmission quality information of the plurality of member links by using a bundled link balancing load algorithm. Wherein, the bundled link balanced load algorithm may be a hash algorithm. For example, the member link with the shortest delay among all the member links of the bundled link may be used as the target link of the delay-sensitive traffic to be transmitted.

And S270, scheduling the traffic to be transmitted to a target link. After the traffic to be transmitted is scheduled to the target link, the traffic to be transmitted can be sent from the first node to the second node through the target link.
