Quality-of-Service Routing in Heterogeneous Networks with Optimal Buffer and Bandwidth Allocation
—We present an interdomain routing protocol for heterogeneous networks employing different queuing service disciplines. Our routing protocol finds optimal interdomain paths with maximum reliability while satisfying the end-to-end jitter and bandwidth constraints in networks employing heterogeneous queuing service disciplines. The quality-of-service (QoS) metrics are represented as functions of link bandwidth, node buffers and the queuing service disciplines employed in the routers along the path. Our scheme allows smart tuning of buffer-space and bandwidth during the routing process to adjust the QoS of the interdomain path. We formulate and solve the bandwidth and buffer allocation problem for a path over heterogeneous networks consisting of different queuing services disciplines such as generalized processor sharing (GPS), packet by packet generalized processor sharing (PGPS) and self-clocked fair queuing (SCFQ). Keywords—Quality-of-service (QoS), resource allocation, inter-domai...
