Network traffic control system

Abstract

A network flow control system in which flow can be controlled by allowing arbitrary setting of a rate limit per communication port even if a switch processor does not support the rate limit function. A network flow control system according to the present invention includes: a switch processor including a plurality of ports connectable to network lines and a packet count register for storing count information on packets input and output through the plurality of ports, for controlling input and output packet traffic of each of the plurality of ports in response to an input flow control command; and a controller for recording the traffic of each of the plurality of ports as a user value in an internal register , wherein the traffic is input through an input input unit, and is used to compare the user value of each of the plurality of ports with the value in a corresponding one of the packet count registers of each port, so as to Input communication control commands for each port are output to the switch processor.

Description

technical field [0001] The present invention relates to a network flow control system, and more particularly to a network flow control system having a switch processor, wherein flow can be controlled by allowing rate limiting to be set per communication port, even if the switch processor does not support rate limiting functionality. Background technique [0002] Interest in computer networking is increasing due to the growth of various network applications, such as Internet-based network applications. As interest in computer networking has increased, techniques dedicated to controlling the traffic conditions of interconnected endpoints on the network have received widespread attention. Such techniques are referred to as "network flow control techniques" and the systems that implement them are referred to as "network flow control systems". [0003] Such as figure 1 As shown, a typical network traffic control system generally includes a switch controller 200 for switching pa...

Problems solved by technology

This can result in loss of transmitted data or control data, which in turn can cause delays in data transmission

[0005] Another problem related to rate limiting is that most manufacturers of switch processors 200 that support the rate limiting function preset the units for setting the input and output traffic to, for example, 8M units

Therefore, from the perspective of switch processor customers, the traffic cannot be set in smaller units such as 1M units considering the special needs of specific customer groups

[0006] Using a switch processor with no rate limiting capability can also cause problems

For this type of switch processor, the amount of traffic allowed per port is preset by the manufacturer as a fixed value, which also makes it difficult to make different settings or adjust the amount of traffic according to the needs of a specific customer group
