Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings. The specific method of operation in the method embodiment may also be applied to the device embodiment or the system embodiment. In the description of the present application, "a plurality of" means "at least two". "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. A is connected with B, and can be represented as follows: both cases of direct connection of A and B and connection of A and B through C. In addition, in the description of the present application, the words "first," "second," and the like are used merely for distinguishing between the descriptions and not be construed as indicating or implying a relative importance or order.
In the prior art, under the condition of the same port link identifier when the CE is accessed to the PE in multiple ways, because the service types in the network are various, and under the condition of the same port link identifier, only an EVPN multiple-way multiple-activity mode or an EVPN multiple-way single-activity mode can be deployed, and each mode can only meet the requirement of one service type in the network, therefore, when the service types in the network are more than one, the different service requirements of a plurality of different service types can not be met under the condition of the same port link identifier.
In order to solve the above-mentioned problems, the embodiments of the present application provide a service forwarding method, which is used to implement decoupling of a control plane and a forwarding plane of an EVPN under the condition of the same port link identifier, so as to simultaneously satisfy respective service requirements of multiple different types of services. The method and the device according to the embodiments of the present application are based on the same technical concept, and because the principles of the problems solved by the method and the device are similar, the embodiments of the device and the method can be referred to each other, and the repetition is not repeated.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 3, the present application provides a service forwarding method, which can implement decoupling of a control plane and a forwarding plane of an EVPN, so as to satisfy service requirements of a plurality of different types of services under the condition of the same port link identifier, and the implementation flow of the method is as follows:
step S31: and obtaining a service to be processed and a control surface corresponding to the service to be processed.
Because the forwarding and transmission of the service in the network are completed through routers at the network side and the user side, in the process of implementing the transmission and forwarding of the service, a control plane and a forwarding plane of the EVPN in the related art are in a coupling state, and the control plane and the forwarding plane have a multi-return single-active mode and a multi-return multi-active mode, which are specifically shown in table 1:
| Control surface | Transfer surface |
| Multiple return single active mode | Multiple return single active mode |
| Multiple return multiple activity mode | Multiple return multiple activity mode |
TABLE 1
In table 1, the control plane and the forwarding plane have a multi-home single-active mode and a multi-home double-active mode, the multi-home single-active mode is that a plurality of user CEs belong to one network PE, the multi-home multiple-active mode is that one user CE belongs to a plurality of network PEs, and since the control plane and the forwarding plane are in a coupling state, when the control plane is in the multi-home single-active mode, the forwarding plane is also in the multi-home single-active mode, when the control plane is in the multi-home multiple-active mode, the forwarding plane is also in the multi-home multiple-active mode, the forwarding plane generally defines the active/standby state of the service node, and the forwarding table in the forwarding plane is as shown in table 2:
TABLE 2
In table 2, the forwarding table when the forwarding plane is in the multiple-return single-active mode is listed, and in table 2, the dual-return single-active is taken as an example, when the main service node receives the service to be processed, the main service node forwards the service to be processed because the forwarding order of the main service node is local priority forwarding; when the standby service node receives the service to be processed, the standby service node forwards the service to be processed to the main service node because the forwarding order of the standby service node is far-end priority forwarding, in the above table 2, the standby service node forwards the service to be processed to the main service node, and then the main service node forwards the service to be processed, and the forwarding table in the forwarding plane in the multi-home single-active mode refers to the above table 2, and the forwarding table in the multi-home single-active mode differs from the forwarding table corresponding to the multi-home single-active mode in that the roles of the service nodes and the forwarding order of the service nodes are different, which is not excessively described herein.
The embodiment of the application aims to enable the control plane and the forwarding plane in the EVPN to be in a decoupling state, so that the accurate control of different types of services under the same port link can be realized, and therefore, the service to be processed is required to be obtained, and the service to be processed can be any service type in a network.
Such as: the service type of the service to be processed can be a home-wide internet service, a government enterprise private line service and the like, the service requirement of the home-wide internet service is to realize load balancing in network transmission, and the service requirement of the government enterprise private line service is to realize accurate flow control in network transmission.
After obtaining the service to be processed, in order to obtain the initial forwarding list of the service to be processed, a control surface to which the service to be processed belongs is also required to be obtained.
Step S32: when the control surface is in a preset state, determining an initial forwarding list corresponding to the service to be processed from forwarding surfaces associated with the control surface.
Because the control surface has the multi-return multi-activity mode and the multi-return single-activity mode, the embodiment of the application is described by the double-return double-activity mode in the multi-return multi-activity mode and the double-return single-activity mode in the multi-return single-activity mode, when the control surface is in the double-return double-activity state, all service nodes corresponding to the service to be processed are firstly determined, the forwarding sequence corresponding to each service node is determined, then an initial forwarding list is generated based on the forwarding sequence corresponding to each service node, and the initial forwarding list is a list normally generated by the control surface in a preset mode.
When the control plane is in the dual-return single-active state, BGP routing information is acquired, and the BGP routing information is used for confirming the active/standby state of the service node, and the specific process for confirming the active/standby state of the service node is as follows:
The embodiment of the application can determine the main and standby states through the IP addresses and VLAN identifications corresponding to each service node, and the mode of determining the main and standby states of the service nodes based on the IP addresses is as follows: sorting all IP addresses according to the sequence from big to small, screening out the minimum IP address, determining the service node corresponding to the minimum IP address, using the service node as a main service node, and using other nodes except the main service node as standby service nodes.
The method for determining the active/standby state of the service node based on the VLAN identifier comprises the following steps: the VLAN identification of each service node and the quantity value which is mostly attributed to the service node at the same user side are obtained, the serial number of the router at the network side is calculated by adopting the following formula I, and the formula I is shown as follows:
V mod N＝i
In the above formula, V represents the VLAN identifier of each service node, the VLAN identifier may be any number between 1 and 4096, N represents the number of PEs classified into the same CE, and i represents the serial number of the PE.
Based on the formula I, the serial numbers of all the service nodes can be calculated, when the serial number is 1, the service node corresponding to the serial number 1 is used as a main service node, and the service node with the serial number not 1 is used as a standby service node.
After the main service node and the standby service node are determined, the main forwarding order of the main service node and the standby forwarding order of the standby service node are determined, and an initial forwarding list is generated based on the main forwarding order and the standby forwarding order.
According to the method, the initial forwarding list can be obtained based on the preset state of the control plane, and the main and standby states and forwarding orders of different services to be processed in different modes of the control plane can be obtained through the initial forwarding list, so that the initial forwarding list can be adjusted.
Step S33: and adjusting the initial forwarding list into a target forwarding list based on the service type of the service to be processed.
Because the initial forwarding list records the forwarding order and the main and standby states corresponding to the service of a certain service type, in order to realize the service requirements of different service types, the initial forwarding list needs to be adjusted to be a target forwarding list meeting the service requirements of the service to be processed based on the service type, so that the decoupling of the control plane and the forwarding plane is realized, all service nodes in the initial forwarding list need to be extracted, then the main service node and the standby service node are determined from all service nodes, then the service type and the preset state of the service to be processed are determined, the main service node and/or the standby service node in the initial forwarding list is adjusted based on a preset instruction, the adjusted initial forwarding list is taken as a target forwarding list, the process of obtaining the target forwarding list is described by way of example for more clear description, and the process of obtaining the target forwarding list is as follows:
In fig. 4, all the services are forwarded from PE3 to CE1 through PE1 and PE2, the forwarding flow of the type a service to be processed is represented by a solid line, the forwarding flow of the type B service to be processed is represented by a dashed line, CE is a router on the user side, and PE is a router on the network side.
If the type a service to be processed is a home broadband internet service and the type B service to be processed is a private line service of an enterprise, because the service requirement of the home broadband internet service is to realize load balancing in network transmission, the service forwarding flow realized in the above-mentioned fig. 4 can meet the service requirement of the type a service to be processed, but because the service requirement of the type B service to be processed is to realize accurate flow control in the network, the service requirement of the type B service to be processed cannot be realized according to the forwarding flow of the dotted line in the above-mentioned fig. 4.
In fig. 4, an initial forwarding list corresponding to the B-type pending service is shown in table 3:
TABLE 3 Table 3
In the above table 3, the forwarding order of each service node is locally and preferentially forwarded as the primary, and the remote forwarding is standby, because the preset state of the current control plane is double-return double-active, when the service to be processed is the B-type service to be processed, only load balancing can be implemented in network transmission according to the forwarding order in the table 3, and the forwarding list in the table 3 will not meet the service requirement of the service to be processed, so that the initial forwarding list needs to be adjusted based on the preset instruction, the service type and the double-return double-active state, and the adjusted target forwarding list is shown in the table 4:
TABLE 4 Table 4
The above table 4 is a target forwarding list of the service to be processed, and adjusts the forwarding order of the standby service node PE2 to be a local (PE 2) forwarding order, the remote (PE 1) forwarding order is the primary, the primary service node PE1 keeps the forwarding order unchanged, the local (PE 1) forwarding order is the primary, and the remote (PE 2) forwarding order is the standby, so the above table 4 can meet the service requirement of implementing accurate flow control in network transmission of the service to be processed.
Under the same port link identifier, because the preset state of the control plane is determined, and the forwarding table in the forwarding plane associated with the control plane is also determined, the control plane and the forwarding plane can be decoupled by adjusting the initial forwarding list to be the target forwarding list, and thus the service requirement of the service to be processed can be met.
According to the method, the initial forwarding list is adjusted to be a target forwarding list which meets the service requirements of the service to be processed based on the preset instruction, so that a forwarding list corresponding to the service to be processed is formed on the forwarding list, decoupling of the control plane and the forwarding plane is further achieved, and the service requirements corresponding to the service to be processed of different service types are achieved under the same port link.
Step S34: and forwarding the service to be processed according to the target forwarding list.
The above-mentioned target forwarding list of the service to be processed has been determined, when the main service node in the network fails and the main service node is redetermined, the main service node will be changed, and when the main service node is changed, the main service node and the standby service node will be interchanged, and the forwarding order of the main service node and the standby service node after interchange is redeployed.
Such as: when the main service node and the standby service node are exchanged, the main service node is used as a target standby service node and the standby service node is used as a target main service node, the forwarding order of the main service node is associated with the target main service node, and the forwarding order of the target standby service node is reset by the preset state of the control surface and the service type of the target standby service node.
When the backup service node is in fault recovery, a corresponding backup forwarding order table is obtained when the backup service node is in fault, and the forwarding plane is controlled to take the backup forwarding order table as a target forwarding order table of the backup service node in fault recovery, and when the backup forwarding order table of the backup service node is in local priority forwarding, the target forwarding order table of the backup service node after fault recovery is also in local priority forwarding; when the standby forwarding order table of the standby service node is the far-end priority forwarding, the target forwarding order table of the standby service node after fault recovery is also the far-end priority forwarding.
