- Abstract
- This paper relates to a traffic control system, and more particularly, to a technique for reducing the load of a traffic control system that has to process a large capacity of traffic on a high-speed line, through policy establishment sequentially by a policy server. Among high-speed data transmission technologies, a traffic control system for internet traffic control on a high-speed line basically requires high performance capable of processing a large capacity of traffic. However, in order to process a large capacity of traffic on a high-speed line, a high performance processor for traffic control is also needed. However, such a high performance processor increases the cost of the traffic control system. For this reason, this paper suggest a method for reducing the load of a traffic control system by allowing the traffic control system to define policies for processing traffic and perform the policies sequentially. The paper's suggesting method include controlling input volume of traffic to the traffic control system based on a filter policy, a system policy, a common service policy, and a subscriber policy in this order, which are established by the traffic control system, according to characteristics of the packet. Therefore, by processing policies sequentially, it is possible to in advance prevent a traffic control system from processing unnecessary traffic. Also, by differentiating policies to be performed for each subscriber and establishing policy layers requiring a relatively long time to process traffic at later stages, it is possible to reduce the load of the traffic control system upon processing traffic and accordingly improve the performance of the traffic control system.
