Constructing a scalable and fail-tolerant Core with multipath routing
Dan Li, Binqiang Wang, Dongnian Cheng, Hailong Ma · 2009
Although benefits comes with decoupling IP dual roles, overload in routers or reallocate a new addressing space for inter-domain routing system is still a great challenge. In this paper, we use the idea of Locator/ID separation but redesign the topological locator to construct a scalable and universal core which can integrate heterogeneous access networks. Moreover, the coarse-grained multipath inter-domain routing (CMIR) as an optional method is offered for fail-tolerant. Simulations illustrate that CMIR can offer good scalability and better fail-tolerating between AS pairs.
