Resilient Traffic Engineering in a Transit-Edge Separated Internet Routing
The significant growth of Internet traffic and increase of routing tables require solutions to address Internet scalability and resiliency. A possible direction is to move away from the flat legacy Internet routing to hierarchical routing, separating edge networks from transit networks. In this paper, the authors study the extended traffic engineering capabilities arising in a transit-edge separated Internet routing, focusing on those multi-homed edge networks (e.g., Cloud/content providers) that aim at increasing their Internet resiliency experience. They model using game theory the interaction between distant independent edge networks exchanging large traffic volumes, with the goal of seeking efficient edge-to-edge load-balanced routing solutions.
