Method for controlling communication flow of network management system

Abstract

The invention discloses a method for controlling the communication flow of a network management system, which is applied to the network management system and realizes the control of the flow of communication messages by adopting multi-level flow control, that is, according to the number of messages and the usage status of memory. The invention comprehensively considers the speed and effectiveness of flow control and the efficiency of system resource utilization, solves the problem of system crash caused by a message storm in a certain module, increases the flexibility of the system, and can realize effective control even for complex systems .

Description

technical field

[0001] The invention relates to a network management system, in particular to a method for controlling communication flow of specific services in the network management system. Background technique

[0002] Usually, in the telecommunication system, some flow control methods are often used to control the data flow, so as to prevent the system from crashing. Generally speaking, the control of data flow can be achieved through the following steps: (1) call request to establish a connection, the key technology of which is connection permission control; (2) monitoring and control of traffic during communication, the key technology is the use of parameter control; ( 3) Congestion control, the key technology is to select cell discarding and congestion indication. Among them, the monitoring and control of the flow can adopt the leaky bucket algorithm, that is, the general cell rate algorithm GCRA (Generic Cell Rate Algorithm). The basic principle is: assuming a fin...
