Description

Method and device for determining interface configuration

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a method and a device for determining interface configuration.

Background

In recent years, ethernet technology has advanced to metropolitan area networks, and Ethernet Virtual Connection (EVC) technology has been proposed by the ethernet forum. In the virtual ethernet, an ethernet frame can be transmitted between an edge device (PE) and the PE, and data transmission is realized through traffic intercommunication. To implement the traffic interworking between PEs of the same service instance, it is necessary that configuration information of an interface on the PEs for receiving the traffic of the service instance conforms to the traffic interworking rule, for example, interface 1 on PE1 and interface 3 on PE2 receive the traffic of the same service instance, the configuration information of interface 1 and the configuration information of interface 3 should conform to the traffic interworking rule, and then interface 1 and interface 3 can implement the traffic interworking.

In the virtual ethernet, traffic interworking rules are easy to understand, which results in that the EVC gradually becomes the mainstream access mode of a layer 2virtual private network (L2 VPN) in the metropolitan area network. In recent years, EVC is increasingly applied to overseas telecommunication operator networks, similar projects of equipment relocation, service transformation and expansion, new service development and the like.

Although the traffic interworking rule is easy to understand, the traffic interworking rule is complex, and a configuration person is easy to configure an error when configuring information for an interface, so that configuration information of the interface between PE devices for receiving traffic of the same service instance does not conform to the traffic interworking rule. Even if the configuration information of the interface between the PE devices for receiving the traffic of the same service instance does not conform to the traffic interworking rule, the existing protocol cannot detect a configuration error because the service instance is in a normal connection UP state, which leads to a problem that the EVC faces poor maintainability in the actual deployment process.

Therefore, a technical solution capable of detecting whether configuration information of an EVC interface between PEs for the same service instance conforms to a traffic interworking rule needs to be provided.

And the first edge device may generate a first message according to the identifier of the target service instance, where the first message includes the identifier of the target service instance, and the first edge device sends the generated first message to the second edge device, so that the second edge device queries the second configuration information, where the second edge device and the first edge device are located in the same virtual ethernet, and the number of the second edge devices may be one or multiple.

Further, the second edge device may also pre-store a third corresponding relationship between the identifier of each service instance deployed in the second edge device and the interface identifier, and may also store a fourth corresponding relationship between each interface identifier in the second edge device and the configuration information; of course, the third correspondence and/or the fourth correspondence may also be stored elsewhere than in the second edge device, such as in a third-party device or in a separate storage medium, etc. The second edge device receives a first message sent by the first edge device, the first message includes an identifier of a target service instance, and the second edge device can determine a second target interface identifier corresponding to the identifier of the target service instance according to a third corresponding relationship between the identifier of each service instance deployed in the second edge device and the interface identifier; and determining second configuration information corresponding to the second target interface identifier according to the configuration information corresponding to each interface identifier stored in the fourth corresponding relationship, and carrying the determined second configuration information in a second message and sending the second message to the first edge device.

Detailed Description

The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

The service scenario described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not form a limitation on the technical solution provided in the embodiment of the present application, and it can be known by a person skilled in the art that with the occurrence of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

In addition, in the embodiments of the present application, the word "exemplary" is used to mean serving as an example, instance, or illustration. Any embodiment or implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or implementations. Rather, the term using examples is intended to present concepts in a concrete fashion.

In order to facilitate understanding of the embodiments of the present application, some terms of the embodiments of the present application are explained below to facilitate understanding by those skilled in the art.

1) The virtual ethernet is a virtual network that operates on the ethernet principle in the real internet and is implemented on the data link layer by a software method, and all applications can be transparently run in the virtual network.

2) And the PE refers to an edge device on a backbone network (backbone network), is adjacent to the CE, and is mainly adapted to access a complex VPN service. It completes the mapping and forwarding of the message from the private network to the public network tunnel and from the public network tunnel to the private network. The PE includes an aggregate provider edge (UPE) of the user.

3) UPE, a device directly connected to a Communication Edge (CE) device is called a lower layer PE, abbreviated as UPE.

4) A Communication Edge (CE) device, may be understood as a customer edge device directly adjacent to a service provider.

5) Virtual Switching Instance (VSI), through which the actual access link of the VPLS can be mapped onto each Virtual link.

6) The access link AC refers to the connection between the CE and the PE, which may be an actual physical connection or a virtual interface, and the user message of the AC generally requires to be forwarded to the remote Site intact, including two or three layer protocol messages of the user.

7) Network cutover, also called network migration, refers to physical or logical change of an operating network, and is the most critical step in network modification. Generally, the service operation of the network requires 24 hours without interruption, and the cutover generally operates on the lines and equipment in use, so the network cutover directly affects the services carried by the lines and equipment, and the cutover can cause interruption of service application in case of carelessness.

8) The PE-AGG and the PE convergence Equipment are used for converging the UPE service and transparently transmitting the service to Network Protection Equipment (NPE).

For the convenience of understanding the embodiments of the present application, an application scenario of the present application will be described below. As shown in fig. 1, a network topology of a metro ethernet network is shown, where PE1 simulates the role of AGG and may communicate with an external network site (site1), PE2, PE3, and PE4 simulate the role of metro lower edge node UPE, PE2 is connected to CE5 and CE2, PE3 is connected to CE3, PE4 is connected to CE4, and site2 to site5 may be understood as user sites; in fig. 1, PE1 may interwork with PE2 and PE3 traffic, respectively, but traffic between PE2 and PE3 cannot interwork, and in an actual physical network, service instances such as VPLS, VLL, EVPN, etc. may be deployed at each edge node.

In the actual service cutover, because the EVC interface forwarding is implemented, after the service deployment is completed, it is necessary to detect whether the interface configuration information of the AGG and the UPE for the service instance conforms to the traffic interworking rule. When detecting whether the interface configuration information meets the flow intercommunication rule, whether VLAN encapsulation setting is reasonable or not and whether flow rewrite action configuration is reasonable or not are mainly detected. In order to avoid the influence on the service opening, as shown in fig. 2, the present application provides a system capable of determining whether the EVC interface configuration conforms to the traffic interworking rule relatively quickly and accurately. The system includes a first edge device 21 and a second edge device 22. The first edge device 21 and the second edge device 22 may be any two edge devices located in the same virtual ethernet, and the first edge device may send an identifier of a service instance to the second edge device, so that the second edge device determines interface configuration information of the service instance and sends the interface configuration information to the first edge device.

As shown in fig. 3, taking the first edge device 21 as a home device and the second edge device 22 as a remote device as an example, the process of interface configuration detection is briefly described, and after receiving the detection instruction, the home device may query its own configuration information and collect the configuration information of the remote device. The detection instruction received by the local device may be sent to the local device by the management device, and the detection instruction sent to the local device by the management device generally includes an identifier of a target service instance with which whether the flows are intercommunicated or not is detected, and may also include an identifier of the remote device. The local terminal equipment can also compare the detection time corresponding to the pre-stored identifier of each service instance with the current time, and trigger the detection instruction by the local terminal equipment. The local terminal equipment stores a flow intercommunication rule base, and can compare and detect the configuration information of the local terminal equipment and the configuration information of the remote terminal equipment according to the flow intercommunication rule base to determine whether the flows are intercommunicated. If the flows are not intercommunicated, an alarm prompt may be performed, for example, the interface identifier and the configuration information of which the flows are not intercommunicated may be displayed on a display interface of the home terminal device or a management interface of the management device. After the comparison detection is performed, the home device may also output the comparison result and the specific content of the configuration information for comparison through the management device or other devices.

The local terminal equipment determines whether the flow intercommunicates with the interface of a certain service instance between the local terminal equipment and the remote terminal equipment by acquiring the interface configuration information of the remote terminal equipment, so that whether the flow intercommunicates can be detected quickly and accurately.

A method and a process for determining interface configuration according to the present application are described below with specific embodiments, where the specific embodiments are applied in a service scenario where one edge device determines whether traffic of the edge device and traffic of another edge device are intercommunicated, for example, the method and the process may be applied in network architectures shown in fig. 1, fig. 2, and fig. 3, where a first edge device in the process is specifically the first edge device 21 shown in fig. 2, and a second edge device in the process is specifically the second edge device 22 shown in fig. 2. Specifically, see steps 401-408 shown in fig. 4:

step 401: the first edge device obtains the identification of the target service instance whether the flow to be inquired is intercommunicated.

In the application, a plurality of service instances may be deployed on a first edge device, where a service instance that determines whether traffic to be queried is intercommunicated may be referred to as a target service instance, and the first edge device needs to know an identifier of the target service instance in order to determine whether traffic of the target service instance is intercommunicated, so that the first edge device may obtain the identifier of the target service instance that determines whether traffic to be queried is intercommunicated.

For example, a user may log in a management system of a first edge device, input or select an identifier of a target service instance on a management interface of the management system, and send the identifier of the target service instance to the first edge device through the management device, so that the first edge device takes the received identifier of the service instance sent by the management device as an identifier of a target service instance for obtaining whether traffic to be queried is intercommunicated.

For another example, the first edge device may also periodically check whether the traffic of the service instances is intercommunicated, for example, the first edge device may configure a detection period for each service instance, and then the first edge device may pre-store a detection time corresponding to an identifier of each service instance, compare the current time with the detection time corresponding to each service instance, determine a target detection time that is the same as the current time, and determine the service instance corresponding to the target detection time as the target service instance, that is, determine the identifier of the service instance corresponding to the target detection time as the identifier of the target service instance. The first edge device may also pre-store a detection time range corresponding to the identifier of each service instance, compare the current time with the detection time range corresponding to each service instance, determine a target detection time range in which the current time falls, and determine the service instance corresponding to the target detection time range as the target service instance.

In virtual ethernet, a VPLS instance, an ethernet virtual private network EVPN service instance, a virtual leased line VLL service instance, etc. may be deployed on an edge device. The target service instance corresponding to the identifier of the target service instance acquired by the first edge device may be a VPLS instance, an EVPN service instance, or a VLL service instance.

Step 402: the first edge device determines a first target interface identifier corresponding to the identifier of the target service instance according to the correspondence between the identifier of each service instance in the first edge device and the interface identifier, which is saved by the first edge device or the third-party device, and determines first configuration information corresponding to the first target interface identifier according to configuration information corresponding to each interface identifier in the first edge device, which is saved by the first edge device or the third-party device.

In one implementation, a first corresponding relationship between an identifier of each service instance deployed in the first edge device and an interface identifier, that is, a corresponding relationship between which interface of the first edge device receives traffic of which service instance, is pre-stored in the first edge device or in a third-party device, and the first edge device may determine, according to the obtained identifier of the target service instance and the first corresponding relationship between the identifier of each service instance deployed in the first edge device and the interface identifier, the interface identifier corresponding to the identifier of the target service instance, where the interface identifier corresponding to the target service instance stored in the first edge is referred to as a first target interface identifier.

The first edge device or the third party device may further store a second corresponding relationship between the interface identifier in the first edge device and the configuration information, that is, store the configuration information of each interface. After determining the first target interface identifier, the first edge device may determine the configuration information corresponding to the first target interface identifier according to a second corresponding relationship between the interface identifier in the first edge device and the configuration information, where the configuration information corresponding to the first target interface identifier is determined as the first configuration information, and the interface identified by the first target interface identifier is the first target interface.

Step 403: the first edge device sends a first message to a second edge device, the first message includes an identifier of the target service instance, and the first edge device and the second edge device are different devices located in the same virtual ethernet.

After obtaining the identifier of the target service instance, the first edge device may generate a first message including the identifier of the target service instance, and send the generated first message to a second edge device located in the same virtual ethernet as the first edge device. When the first edge device sends the first message to the second edge device, the first edge device may first obtain an identifier, such as an IP address, of the second edge device, and send the first message to the second edge device according to the identifier of the second edge device.

The target service instance may be one or multiple, and if multiple target service instances exist, the target service instances may be sent in multiple first messages.

In general, the second edge device is also deployed with a target service instance, and when determining the second edge device, the first edge device may receive, by the management device, an identifier of the second edge device sent by the management device, where the identifier of the second edge device sent by the management device to the first edge device may be determined on the management device by a user. When the first edge device determines the second edge device, the first edge device may also store, for each service instance, an identifier of the edge device where the service instance is deployed, that is, a correspondence between the identifier of the service instance and the identifier of the edge device. After obtaining the identifier of the target service instance, the first edge device may determine, according to a correspondence between the identifier of the pre-stored service instance and the identifier of the edge device, the identifier of the edge device corresponding to the identifier of the target service instance, and determine the identifier of the edge device corresponding to the identifier of the target service instance as the identifier of the second edge device. The number of the second edge devices may be one or multiple, and if there are multiple second edge devices, the first edge device may send the first message to each of the second edge devices.

The first message sent by the first edge device to the second edge device may be an ICMP request message, and the identifier of the target service instance included in the first message may be carried in an extension field of a header of the ICMP request message.

Step 404: the second edge device searches configuration information of an interface that receives traffic of the target service instance according to the identifier of the target service instance in the first message, where a third correspondence between the identifier of each service instance deployed in the second edge device and the interface identifier may be pre-stored in the second edge device or in a third-party device, that is, a correspondence between which interface in the second edge device receives traffic of which service instance, and the second edge device may determine the interface identifier corresponding to the identifier of the target service instance according to the identifier of the target service instance in the first message sent by the first edge device and the third correspondence between the identifier of each service instance deployed in the second edge device and the interface identifier, where the interface identifier corresponding to the target service instance stored in the second edge is referred to as a second target interface identifier.

Further, the second edge device or the third party device may further store a fourth corresponding relationship between the interface identification information and the configuration information in the second edge device, that is, store the configuration information of each interface in the second edge device. After determining the second target interface identifier, the second edge device may determine the configuration information corresponding to the second target interface identifier according to a fourth corresponding relationship between the interface identifier in the second edge device and the configuration information, where the configuration information corresponding to the second target interface identifier is determined as the second configuration information, the interface identified by the second target interface identifier is the second target interface, and the second target interface identifier may also be understood as the identifier of the second target interface.

Step 405: after determining second configuration information corresponding to each second target interface identifier of the second edge device, the second edge device may generate a second message including the second configuration information, and send the second message to the first edge device.

The second edge device may determine that there is one or more second target interface identifiers, if there are multiple second target interface identifiers, the second configuration information is multiple, when the second edge device sends the second message to the first edge device, the second edge device may split the second message into multiple pieces of second messages, each piece of second message includes configuration information of one second target interface identifier, or may carry second configuration information of multiple second target interface identifiers in one piece of second message.

Step 406: the first edge device receives a second message sent by the second edge device, where the second message includes second configuration information, and the second message may be understood as an ICMP response message, and there may be a plurality of second destination interfaces in the second edge device, where the second destination interfaces are used to receive traffic of a destination service instance, and there are a plurality of second configuration information sent by the second edge device to the first edge device.

Step 407: the first edge device compares the first configuration information determined in step 402 with the second configuration information carried in the second message received in step 406, and determines whether the flows of the first target interface and the second target interface for the target service instance are intercommunicated according to a comparison result.

For example, a traffic interworking rule may be pre-stored in the first edge device, and after finding first configuration information of a first target interface of the first edge device for a target service instance, and receiving second configuration information of a second target interface of the second edge device for the target service instance, which is found by the second edge device, the first edge device may compare the first configuration information with the second configuration information according to the pre-stored traffic interworking rule, and determine whether a first target interface corresponding to the first configuration information and a second target interface corresponding to the second configuration information are in traffic interworking according to a comparison result of the first configuration information and the second configuration information.

In the application embodiment, the first edge device compares the first configuration information of the first target interface, which receives the traffic of the target service instance, with the second configuration information of the second target interface, which receives the traffic of the target service instance, in the second edge device, to determine whether the first target interface and the second target interface are intercommunicated with respect to the traffic of the target service instance, so that the purpose of quickly and accurately detecting whether the traffic of the interfaces, which are used for receiving the traffic of the same service instance, is intercommunicated between two PEs can be achieved.

In order to make the inspector clearly know whether the flows between the PE devices are intercommunicated, in this application, after step 407 is completed, step 408 may be performed, where step 408: the first edge device or the management device outputs the respective configuration information of the two edge devices and the comparison result of the configuration information, and if the comparison result is that the flow is not intercommunicated, an alarm prompt can be given.

In the foregoing process, the first message sent by the first edge device to the second edge device may be an ICMP message, and for example, the identifier of the target service instance included in the first message may be carried in an extension field of a header of the ICMP message.

The following describes an ICMP message format sent by a first edge device to a second edge device: as shown in fig. 5, the ICMP message includes an IP header area and an ICMP message area, where a field "type" in the ICMP message header indicates a type of the message, the type of the ICMP message includes a request message, a response message, and the like, and different values are given to the field "type" to indicate different types of the ICMP message, for example, when the field "type" takes a value of 0, it indicates that the ICMP message is a request message, and when the field "type" takes a value of 1, it indicates that the ICMP message is a response message. The field "type" is typically 8 bits in length.

The value rule of the field "checksum" is the same as that specified in the existing ICMP protocol, and will not be described here, and the length of the field "checksum" is typically 16 bits.

When the value of the field identifier is 0, the target service instance is represented as a VPLS instance, namely the field ID represents a VSI ID; when the value is 1, the target service instance is denoted as VLL, that is, "field" ID "denotes" VLL L2VC ID "; when the value is 2, the target service instance is EVPN, namely the field ID represents EVPN vpn-target.

The field "ID" has a corresponding length, and when the value of the "identifier" is 0 or 1, the ID length may be 3 bytes, and when the value of the "identifier" is 2, the ID length may be 12 bytes.

The field "identifier" and the field "ID" are not defined in the existing ICMP header. The option data in fig. 5 can be understood as a temporary undefined portion.

In the application, a Ping vpn-config command can be newly added, and the configuration information of the EVC of the remote equipment for the service instance is detected based on the EVC-AC field.

If the VPLS command acts: ping vpn-config peer-address [ B.B.B.B ] vsi-id [ XX ] EVC-AC; the AC in the command behavior indicates detection of AC side configuration, implemented by adding an identifier, [ b.b.b.b ] indicates identification of the second edge device, which may be the IP address of the edge device, and vsi-id XX may indicate identification of the VPLS instance.

The first edge device pings the second edge device, i.e., initiates a configuration information query of the EVC to the second edge device.

After receiving the ping message, the second edge device may query a local VPLS instance according to the VSI-ID, and send configuration information of all interfaces for receiving traffic of the VPLS instance to the first edge device in a packet manner.

The configuration information may include: interface identification, VLAN encapsulation information and flow information. The receiving identification can be an interface name, such as Eth-Trunk 126.1, the packaging information can be qinq vid 601ce-vid 1, and the flow information can be a rewrite pop single.

The number of the interfaces of the first edge device that receive the traffic of the target service instance may be one, or may be multiple, that is, the first edge device may determine the first target interface identifier as one, or may be multiple. The number of interfaces of the second edge device that receive the traffic of the target service instance may be one or multiple, that is, the second edge device may determine that the identifier of the second target interface is one or multiple.

If the first target interface identifiers are at least two and/or the second target interface identifiers are at least two, the first edge device compares first configuration information with second configuration information, and determines whether the flows of the first target interface and the second target interface for the target service instance are intercommunicated according to a comparison result, and can compare the first configuration information corresponding to each first target interface identifier with the second configuration information corresponding to each second target interface identifier.

Illustratively, the first edge device compares first configuration information corresponding to a first target interface identifier i with second configuration information corresponding to a second target interface identifier j, and determines whether a flow of an interface corresponding to the first target interface identifier i and a flow of an interface corresponding to the second target interface identifier j are communicated with each other for the target service instance according to a comparison result;

the first target interface identifier determined by the first edge device is identified by i, if the number of the first target interface identifiers is N, i traverses any integer from 1 to N, the second target interface identifier determined by the second edge device may be identified by j, and if the number of the second target interface identifiers is M, j traverses any integer from 1 to M.

Assuming that N is 2, there are two first target interface identifiers, namely a first target interface identifier 1 and a first target interface identifier 2, for convenience of description, the first target interface identifier 1 is simply referred to as "a", and the first target interface identifier 2 is simply referred to as "b". Assuming that M is 3, there are three second target interface identifiers, which are respectively the second target interface identifier 1, the second target interface identifier 2, and the second target interface identifier 3, for convenience of description, the second target interface identifier 1 is simply referred to as c, the second target interface identifier 2 is simply referred to as d, and the second target interface identifier 3 is simply referred to as e. In determining whether the traffic is interworking, the following steps may be performed:

comparing the first configuration information corresponding to the a with the second configuration information corresponding to the c, and determining whether the flow intercommunication exists between the interface identified by the a and the interface identified by the c aiming at the target service instance;

comparing the first configuration information corresponding to the a with the second configuration information corresponding to the d, and determining whether the flow intercommunication exists between the interface identified by the a and the interface identified by the d aiming at the target service instance;

comparing the first configuration information corresponding to the a with the second configuration information corresponding to the e, and determining whether the flow intercommunication exists between the interface of the a identifier and the interface of the e identifier aiming at the target service instance;

comparing the first configuration information corresponding to the b with the second configuration information corresponding to the c, and determining whether the flow intercommunication exists between the interface identified by the b and the interface identified by the c aiming at the target service instance;

comparing the first configuration information corresponding to the b with the second configuration information corresponding to the d, and determining whether the flow intercommunication exists between the interface identified by the a and the interface identified by the d aiming at the target service instance;

and comparing the first configuration information corresponding to the b with the second configuration information corresponding to the e, and determining whether the flow intercommunication exists between the interface identified by the b and the interface identified by the e aiming at the target service instance.

By comparing each first target interface on the first edge device with the configuration information of each second target interface on the second edge device, whether the configuration information of any two interfaces of the target service instance are intercommunicated is determined, and further whether the flow among the PEs is intercommunicated is accurately and comprehensively detected.

In this application, the configuration information of the interface may include VLAN encapsulation information and flow operation information, and the first configuration information may include VLAN encapsulation information and/or flow operation information; the second configuration information may include VLAN encapsulation information and/or flow operation information.

The VLAN encapsulation information may include: no package, one layer of VLAN package, two layers of VLAN package, value of each layer of VLAN, etc.; the encapsulation information in the first configuration information may include any one of no encapsulation, one layer of VLAN encapsulation, and two layers of VLAN encapsulation, and if VLAN is encapsulated, a value of each layer of VLAN may be included. The encapsulation information in the second configuration information may include any one of no encapsulation, one-layer VLAN encapsulation, and two-layer VLAN encapsulation.

The flow action information may include: default action, pop-up pop action, push-in push action, swap action, map action, etc.; for each layer of VLAN, the corresponding flow information is provided. The flow action information in the first configuration information may include at least one of a default action, a pop-up pop action, a push-push action, a swap action, and a map action. The flow action information in the second configuration information may include at least one of a default action, a pop-up pop action, a push-push action, a swap action, and a map action. The default action described above may be considered an unconfigured action.

In this application, whether the flows of the interface corresponding to the first configuration information and the interface corresponding to the second configuration information are intercommunicated may be determined by comparing the encapsulation information and the flow operation information in the first configuration information with the encapsulation information and the flow operation information in the second configuration information.

In this application, as an example, if the encapsulation information in any configuration information is an encapsulation VLAN and the flow action information is a default action, and the encapsulation information in another configuration information is an encapsulation layer VLAN and the flow action information corresponding to the layer VLAN is a pop-up pop action, it is determined that the flows of the interface corresponding to the first target interface identifier i and the interface corresponding to the second target interface identifier j are not intercommunicated with each other for the target service instance.

For example, if the encapsulation information in any configuration information is an encapsulation VLAN, the flow action information is a default action, the encapsulation information in another configuration information is an encapsulation two-layer VLAN, and the flow action information corresponding to each of the two-layer VLANs is a pop-up pop action, it is determined that the flows of the interface corresponding to the first target interface identifier i and the interface corresponding to the second target interface identifier j are not intercommunicated with each other for the target service instance.

For example, the configuration information of the local device is to encapsulate a layer vlan, which uses the pop action: "dot 1q vid XX; rewrite pop ", the configuration information of the remote device is to encapsulate a layer of vlan, which uses a push action: "dot 1q vid XX; rewrite push ", the traffic of the two end devices for the target service instance vid XX cannot be intercommunicated.

In the application, whether the flow is intercommunicated can be determined by comparing the values of the VLANs.

Illustratively, if the encapsulation information in any configuration information is an encapsulated layer VLAN, and the flow action information corresponding to the layer VLAN is a default action, the encapsulation information in another configuration information is an encapsulated two-layer VLAN, and the flow action information corresponding to a first layer VLAN in the two-layer VLAN is a pop action, it is determined whether a VLAN value in any configuration information is the same as a VLAN value in a second layer VLAN in the other configuration information, if not, it is determined that an interface corresponding to a first target interface identifier i and an interface corresponding to a second target interface identifier j are not intercommunicated with respect to the traffic of a target service instance, and if they are the same, it is determined that an interface corresponding to the first target interface identifier i and an interface corresponding to the second target interface identifier j are intercommunicated with respect to the traffic of the target service instance;

the encapsulation information in the configuration information in the above example is an encapsulation VLAN, which may be understood as encapsulating a layer of VLAN or encapsulating a layer of VLAN.

If any of the configuration information in the above examples is first configuration information, the other configuration information is second configuration information; or if any of the configuration information in the above examples is the second configuration information, the other configuration information is the first configuration information.

When two layers of VLANs are packaged, the VLANs are divided into an inner layer and an outer layer, and if the first layer in the example is the inner layer, the second layer is the outer layer; or if the first layer of the above example is an outer layer, the second layer is an inner layer.

And comparing the first configuration information with the second configuration information, and determining whether the flow of the interface corresponding to the first target interface identifier and the flow of the interface corresponding to the second target interface identifier are intercommunicated aiming at the target service instance or not according to the comparison result.

In another embodiment of the present application, metro networking may also improve Software Defined Networking (SDN) in consideration of future network evolution trend. In the SDN, the management system is centrally managed, and the management system may be deployed on an extensible Node Controller (SNC), so that the SNC may be regarded as a management device.

As shown in the system structure diagram of fig. 6, in the management device 61, an identifier of a target service instance is sent to a first edge device 62 and a second edge device 63, first configuration information for the target service instance sent by the first edge device 62 is received, and second configuration information for the target service instance sent by the second edge device 63 is received. The management device 61 compares the first configuration information with the second configuration information, and determines whether the flows of the first edge device 62 and the second edge device 63 for the target service instance are intercommunicated. The first edge device 62 may be the first edge device 21, the second edge device 22 shown in fig. 2, the UPE, AGG, etc. shown in fig. 1, and the second edge device 63 may be the first edge device 21, the second edge device 22 shown in fig. 2, the UPE, AGG, etc. shown in fig. 1.

A method and a process for determining an interface configuration according to the present application are described in the following with specific embodiments, where a management device in the process is specifically the management device 61 shown in fig. 6, a first edge device in the process may be specifically the first edge device 62 shown in fig. 6, and a second edge device in the process may be specifically the second edge device 63 shown in fig. 6, and specifically refer to steps 701 to 708 shown in fig. 7:

step 701: the management equipment acquires the identification of a target service instance, wherein the target service instance is a service instance for inquiring whether the flow is intercommunicated.

For example, the detection personnel may operate on the management device to determine the identifier of the target service instance, so that the management device may receive the identifier of the target service instance determined by the user. Thus, the detection of whether the flow of a specific service instance is intercommunicated can be completed through the identification used for specifying the target service instance.

For another example, the management device may set a detection period for each service instance, and prestore detection time corresponding to the identifier of each service instance; the management device may determine, according to the detection time corresponding to the identifier of each service instance stored in advance, the target detection time that is the same as the current time, and determine the identifier of the service instance corresponding to the target detection time as the identifier of the target service instance. By setting the detection time for each service instance, whether the flow of each service instance is communicated or not can be regularly detected.

Step 704: the first edge device carries the determined first configuration information in a third message and sends the third message to the management device, and the management device receives the third message sent by the first edge device, wherein the third message comprises the first configuration information. The specific process of step 704 is similar to that of steps 405 and 406, and will not be described herein again.

Step 705: the second edge device pre-stores a third corresponding relationship between the identifier of each service instance deployed in the second edge device and the interface identifier, and also stores a fourth corresponding relationship between each interface identifier in the second edge device and the configuration information; of course, the third correspondence and/or the fourth correspondence may also be stored elsewhere than in the second edge device, such as in a third-party device or in a separate storage medium, etc. The second edge device receives a first message sent by the management device, where the first message includes an identifier of a target service instance, and the second edge device may determine, according to a third correspondence between the identifier of each service instance deployed in the second edge device and an interface identifier, a second target interface identifier corresponding to the identifier of the target service instance; and determining second configuration information corresponding to the second target interface identifier according to the configuration information corresponding to each interface identifier stored in the fourth corresponding relationship, and carrying the determined second configuration information in a second message and sending the second message to the management device.

Step 706: and the second edge device carries the determined second configuration information in a second message and sends the second message to the management device, and the management device receives the second message sent by the second edge device, wherein the second message comprises the second configuration information. The specific process of step 706 is similar to that of steps 405 and 406, and is not described herein again.

Step 707: the management equipment compares first configuration information corresponding to the first target interface identifier with second configuration information corresponding to the second target interface identifier, and determines whether the flow of the interface corresponding to the first target interface identifier and the flow of the interface corresponding to the second target interface identifier are communicated with each other aiming at the target service instance or not according to a comparison result.
