Intelligent computer network routing using logically centralized, physically distributed servers distinct from network routers |
摘要 |
A route control architecture allows a network operator to flexibly control routing between the traffic ingresses and egresses in a computer network, without modifying existing routers. An intelligent route service control point (IRSCP) replaces distributed BGP decision processes of conventional network routers with a route computation that is flexible and logically centralized but physically distributed. One embodiment supplements the traditional BGP decision process with a ranking decision process that allows route-control applications to explicitly rank traffic egresses on a per-destination, per-router basis. A straightforward set of correctness requirements prevents routing anomalies in implementations that are scalable and fault-tolerant. |
