Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for implementing interface index consistency.
Background
The Broadband Access Server (BRAS) is a product of the service evolution of the metropolitan area network. The business of the metropolitan area network is continuously developed, and under the condition that only access equipment and a backbone router exist, a user cannot perform authentication and authorization management, so that the operation management and the long-term development of the network are not facilitated. After introducing BRAS between access network and backbone network, BRAS is used as access gateway of network service, providing broadband access, authentication, authorization and charging for users, managing user bandwidth, converging user service flow, terminating Point-to-Point Protocol Over Ethernet (PPPoE) connection on user Ethernet, and providing multiple service.
As shown in fig. 1, fig. 1 is a schematic diagram of a transfer control separation architecture in the prior art. In fig. 1, a virtual machine (vm) is divided into three roles. Namely: control vm (CTRL-vm), forwarding vm (FWD-vm), and BRAS-vm. BRAS-CP runs in vm comprised by several tens of servers with virtualization technology, as shown within the dashed box shown in fig. 1.
CTRL-vm is in a main standby mode; the BRAS-vm is also in a master-standby mode and is managed by the CTRL-vm; FWD-vm is a separate network element and is subject to the management of CTRL-vm. BRAS-UP may communicate with BRAS-vm by forwarding vm. The FWD-vm is responsible for message forwarding between CTRL-vm and BRAS-UP; CTRL-vm can remotely configure and view the configuration in all vm's through local commands, and CTRL-vm can also control the communication between all vm's.
There are multiple types of interfaces on BRAS-CP, and the distribution of the multiple types of interfaces at each vm is shown in table 1 below:
table 1 distribution of multiple types of access in different vm
Note:
indicating that interface information exists, but no operational data, only for configuration;
the check mark indicates that the interface information exists and the operation data also exists, and the check mark is not only used for configuration but also used for operation of the service;
x denotes that interface information does not exist.
Because the OM channel is used as the only channel for controlling and configuring the BRAS-CP by peripheral equipment (such as an SNMP client, a NETCONF client and a command line terminal), for the configuration or display of an interface, a CTRL-vm is required to send a NETCONF request to a vm with the interface, and after the vm is processed, a processing result is returned to the CTRL-vm and is displayed by the CTRL-vm.
At this time, if the interface of the FWD-vm or BRAS-vm has configured the SNMP trap mode, when the FWD-vm or BRAS-vm sends a trap message, it needs to distinguish whether the trap message is related to the interface. And if the trap message is related to the interface, the vm adds interface name information in the trap message and transparently transmits the trap message to the CTRL-vm. The CTRL-vm converts the interface name into an interface index in the CTRL-vm, and after the conversion is completed, the CTRL-vm sends the interface index to a Simple Network Management Protocol (SNMP) client.
However, the above-mentioned method of exchanging trap information also brings the following problems: 1) each vm is a device independent of each other, and interfaces of the same type may exist in different vms, but because each vm only allocates an interface index of an interface in the vm, the interface indexes of the interfaces of the same type cannot be consistent; 2) before sending a trap message, each vm needs to obtain interface name information through an interface index allocated to the vm, and then the interface name information is packaged in a newly-added field. The CTRL-vm needs to analyze the interface name information in the newly added field, convert the interface name into an interface index in the CTRL-vm, replace the index before conversion with the converted index and send the index to the SNMP client, so that the efficiency is influenced; 3) fields need to be added in the trap message to represent interface name information, so that the coupling degree between each vm is increased.
