A time limit and hop based queue management and scheduling technique for a remote technical consultation system on the Internet

The purpose of this paper is to describe a new active queue management and packet scheduling technique to be used by real-time Internet video applications. In this technique packets are classified into classes according to its importance to the application. Also, every packet is marked with a time limit to arrive at the destination and the expected number of hops until arrival. It is used as a measure of distance. Time limit and number of hops are combined to form a relay priority for forwarding and are used to find the packet a preferential position in the router output queue. Packet transmission using this technique helps us assure quality of service to the operation of real-time video applications.
