  ABSTRACT: High availability WAN connectivity has traditionally been implemented with a single service provider building links with high quality hardware, redundancy, and SLA guarantees. We have studied and implemented an alternative, a MIP-based overlay approach that is both economical and can be deployed in present-day Internet. In this paper, we investigate the performance of our implementation of a Redundant Array of Independent Internet Connections (RAIIC) and based on results, propose additional modifications to the approach.

  ABSTRACT: 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.
