US 2006/0218290 A1 · System and method of request scheduling for differentiated quality of service at an intermediary

Abstract

A system and a method of request scheduling for differentiated quality of services at an intermediary are provided. An intermediary located between clients and a server is used to schedule requests from the clients in the Internet. The intermediary classifies the requests and decides resources required for each request according to the administrative policies. Then the intermediary decides the order and the time the requests being transferred to the server by the size of the responses corresponding to the requests, window control and server loading. Therefore, the system is transparent to clients and servers and is capable of high compatibility with other systems.

Dependent claims

A system of request scheduling applied in a network for differentiated quality of service at an intermediary between at least a client and an application server, comprising:

a prober for checking at least a request items to said application server and correspondent size of responses of said requests, and registering in a request/respond list;
a classifier for establishing a service quality policy list and classifying said requests received from said clients;
class queues for setting at least a queue corresponding to said service quality policy list and storing said classified requests into said queues;
and
a scheduler for setting each said queue with a corresponding service quantum, setting a scheduler pointer and a scheduling window size, and transferring said queued requests to said application server in a scheduler manner according to size of responses to said requests.
