Method and system for dynamically distributing network traffic

Abstract

The invention discloses a method and a system for dynamically distributing network traffic, and relates to the field of internet, which are used for solving the problem that the prior art cannot avoid bandwidth waste or congestion phenomenon under the condition of the dynamic change of network bandwidth. The method comprises the following steps of: monitoring gateway exit bandwidth at definite time to acquire the current bandwidth data; calculating the traffic of each traffic use unit, which can be distributed from the current bandwidth, according to a traffic distribution strategy and a traffic redistribution algorithm; and redistributing the traffic for each traffic use unit according to the calculating result. The system comprises a monitoring module, a calculating module and a redistributing module. A mechanism for monitoring the gateway exit bandwidth at definite time exists; the traffic of each traffic use unit, which can be distributed from the current bandwidth, can be calculated according to the traffic distribution strategy and the traffic redistribution algorithm; then the traffic redistribution is performed; and therefore, the method and the system have the advantages of realizing the dynamic distribution of the network traffic, effectively and reasonably utilizing the bandwidth and avoiding the bandwidth waste or congestion phenomenon.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a method and system for dynamically allocating network traffic. Background technique [0002] At present, network applications are more and more widely used, but bandwidth is increasingly tight, which requires IP networks to provide users with better traffic management to avoid misuse, abuse or waste of traffic. [0003] The currently proposed traffic schemes are mainly based on IP current limiting or based on differentiated services (DiffServ). IP current limiting is to limit the uplink and downlink bandwidth of the traffic entering and leaving the network through the five elements of IP (source address, destination address, source port, destination port, protocol). This method is relatively simple, but it cannot allocate bandwidth effectively and reasonably when the IP address changes or the IP traffic is unstable. DiffServ traffic distribution only treats data packets differently...
