Embodiment Construction

[0031] Aiming at the problem that a lot of work needs to be done in order to distinguish the source of the control command in the traditional technology, resulting in low development efficiency and system instability, the present invention provides a system and method for realizing multi-master remote procedure call. The basic idea is as follows: : Number the MPU of each stack member device, and encapsulate the MPU number in the RPC serial number. The LPU determines which MPU the instruction comes from according to the MPU number in the serial number. It is easy to expand the RPC to support the stacking system, improve development efficiency, and improve the system. stability.

[0032] see Figure 5 , the system that implements multi-master remote procedure calls in this example includes:

[0033] Call the management module to set the MPU number for the main control card of the stack member device, and assign the RPC serial number counter to the MPU;

[0034] The MPU number ...

Abstract

The invention relates to a route switching control technology in the field of network communication and discloses a method for realizing multi-master-control remote procedure call (RPC), which is used for solving the problems of low development efficiency and unstable system caused by heavy workload required for distinguishing sources of control instructions in the traditional technology. In the method, an MPU (Micro Processor Unit) of each stack member equipment is numbered, the serial numbers of the MPUs are packaged in an RPC serial number, an LPU (Line Processing Unit) determines which MPUs the instructions are from according to the serial numbers of the MPUs in the serial number, and thus, the RPC-supported stack system is easily expanded, the development efficiency is increased, and the stability of the system is improved. In addition, the invention discloses a system for realizing multi-master-control remote procedure call, which is suitable for the stack system.

Description

technical field [0001] The present invention relates to routing switching control technology in the field of network communication, in particular to a method and system for realizing multi-master remote procedure call (Remote Procedure Call, RPC for short). Background technique [0002] At present, the system architecture of mainstream routing and switching equipment is generally divided into three subsystems: data plane, control plane and monitoring plane. Among them, the control plane includes the main control card MPU control plane and the service line card LPU control plane. The MPU control plane is responsible for protocol calculation and the management of the entire device. The LPU control plane is responsible for the setting and management of hardware chips. The MPU sends commands to the LPU through RPC. To realize the operation of the hardware chip, such as figure 1 As shown, the MPU sends instructions to each LPU through RPC; figure 2 shows the RPC implementation...
