Abstract

In the highly connected Internet, most of domains (Autonomous Systems, ASes) have more than one interconnection link to different providers. In this multi-homed scenario, destinations for inter-domain traffic may be reachable through multiple egress routers with various offered cost and path performance. In this paper, the problem of route selection in a multi-homed stub network to optimize transit costs and paths performance offered by an operator to its customers is addressed. The length of an AS-path and latency experienced on that path measured by round-trip-time (RTT) are treated as the indicators of quality of service (QoS) related to interconnections and routes offered by interconnected partners. Some QoS optimization models together with heuristic algorithms to solve the problem are presented. To evaluate the performance of the proposed optimization models a Least Cost Routing solution supporting optimal routing decisions has been used. The results indicate that taking into account both cost and performance is crucial for assuring an acceptable level of service for end-users with optimized cost for the operator.
