Intra Autonomous System Overlay Dedicated to Communication Resilience

摘要

Some services delivered in IP networks, like IP television, Telephony over IP and critical services, have strong robustness requirements. Consequently, the communications delivering those services must be resilient to failures in the network. This paper proposes a new approach to improve communication protection. It consists in deploying a routing overlay dedicated to resilience in an autonomous system, and it reduces connectivity restoration time after a failure (compared to standard routing protocols). Finally, we validate this proposal under different scenarios on an emulated testbed.
