Development of a scheduler for quality of service support in IP networks

The current IP-based networks are described as best effort. When a packet arrives at a router, the router looks at the destination address, checks with the routing-table entries, then selects the best match and sends the packet to the output queue. The routing is dynamic where the packets in a singl...

When a packet arrives at a router, the router looks at the destination address, checks with the routing-table entries, then selects the best match and sends the packet to the output queue.
