QoS sensitive domain routing for load balancing network

In this paper, a QoS sensitive domain, which supports load balancing in a large communication network, is developed. Its compatible routing algorithm consists of two levels. In a given sensitive domain, border nodes finish inter-domain routing level, and then intra-domain routing level is accomplished on all nodes. Two coterminous routing algorithms are taken to emphasize particularly on load balancing of inter-domain and intra-domain. By replacing a set of traditional QoS parameters with an approximate line segment, I simplify QoS expression. Line segments are grouped to form a swapping matrix that may lead to the reduction of route computations.
