Due to all these factors, the performance of data delivery over Internet degrades which hits hard especially delivery of audio, video and other time and bandwidth sensitive media. However, these approaches satisfy only retrieval multimedia applications. There are many changes which need to be put in place in current Internet to improve the performance of the shared network resource and quality of delivered digital media such as video and audio for future applications.
Improved Internet means increase of users acceptance and revenues.
One of the changes which need to be done to improve Internet performance for multimedia traffic is the routing of IP packets. We believe that the IP routing will need to be based on QoS requirements such as bandwidth and timing constraints. This will require changes in state information at the routers and change in protocols determining the routes between sources and destinations. Current routing protocols do not reflect these QoS requirements. Each router is responsible for keeping track and informing its neighbors of its distance to each destination.
