Service Oriented Real-time Buffer Management for Qos on Adaptive Routers

To increase the quality of service in adaptive routers, this paper proposes a service oriented buffer management algorithm. This paper use different buffers for different service packets and the buffer controller maintains the buffer size according to flow of incoming packets. The buffer controller increases or decreases the buffer size at each input and output port by monitoring the rate of incoming packets and the size of buffer is fixed based on a flow threshold which is dynamic one. The value of flow threshold is computed using dynamic flow approximation algorithm. The proposed system reduces the packet dropping rate and increases the throughput.
