Prioritization of data to be transmitted in a router

Abstract

General Packet Radio Service is a new service designed for digital mobile systems. Because of bottlenecks, such as an air interface (Um), queues may be formed in routers. Long transmissions of data may slow the operation of interactive applications so that it is no longer sensible to use the applications. In the routers, separate queues are formed for each service, quality of service, connection, subscriber and/or application/application class. Quality of service can be indicated by providing each packet with an identity indicating the quality, or a change in the quality can be signalled as separate messages. The amount of data sent from a queue at one go may be controlled primarily based on quality of service of the subscriber. When packets are sent from a queue, it is monitored whether only a small number of packets remains in the queue, and if so, these packets are sent as well.
