System and method for flow control based on network medium

Abstract

The invention discloses a flow control system and method based on a network medium, and relates to the field of network communication. The method comprises the following steps: the forwarding plane establishes a physical channel, confirms the real-time bandwidth of each type of physical channel according to the type of the physical channel, and reports it to the control plane; the control plane generates a corresponding interface according to the type of the physical channel, and according to the type of the physical channel Real-time bandwidth, calculate the traffic shaping parameters of the interface, and shape the traffic. The invention can adjust the bandwidth in real time, and in the case of traffic burst, the message can be sent out at a relatively uniform speed, thereby reducing the requirement on the hardware buffer of the forwarding plane.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a flow control system and method based on network media. Background technique [0002] The current data communication equipment is usually divided into a control plane and a forwarding plane. The GCC (General Communication Channel) overhead of the OTN (Optical Transport Network, Optical Transport Network) signaling network is used as an example to illustrate. The normal processing flow is: control The application layer and protocol module of the plane send management data, and send it to the forwarding plane through the signaling channel; the forwarding plane first caches the data in the hardware buffer, waits for OTN framing and photoelectric crossover processing, and then sends the data to the data line superior. [0003] Since the GCC general communication channel can only carry two bytes of network management data per frame, only two bytes of network management data can ...

AI Technical Summary

Problems solved by technology

[0004] (1) The control plane cannot perceive the network congestion of the forwarding plane, and the continuous sending of message data will increase the network burden;

[0005] (2) When the hardware buffer of the forwarding plane is full, it will cause problems such as packet loss, packet data inspection and abnormality, which will cause inconsistency problems caused by the transmission of invalid frames on the actual line;

[0006] (3) The data channel lacks a management mechanism, and cannot provide effective flow control and data statistics functions, as well as related supervision mechanisms

[0007] In view of the problems existing in the traditional solution, a large number of network management data transmission requirements can be met by increasing the hardware buffer. There will also be invalidation of the cache; another solution is to increase the number of bytes of management data transmitted per frame to increase bandwidth, but it is not optimal when the cost of channel curing and modifying the frame encapsulation format is high Program
