Space-efficient signaling scheme for Home Agent assisted Route Optimization for use in virtual networks

As residential Internet access has become increasingly commoditized, the incentives to lower costs in enterprise and similar networks with service level agreements have grown as well. Simply switching to a VPN provided over Internet brings cost savings but at the same time loses any guarantees of service level. We have devised a Mobile IP-based approach to virtualize networks without neglecting Quality of Service. As part of this specific approach, the signaling traffic levels go up as complexity of the network grows. To mitigate this issue, we have created a simple yet effective scheme to compress information on IPv4 prefixes and realms. In this paper, we present analysis of our scheme´s effectiveness and feasibility using both generated and real-world test material.
