A METHOD AND SYSTEM FOR PROVIDING AROUTING ARCHITECTURE FOR OVERLAY NETWORKS

摘要

A link state overlay routing protocol that is capable of routing based on flat identifiers is proposed. The very fundamental problem that exists with 5 routing based on flat identifiers is that the identifier space can not be aggregated. All existing routing is based on hierarchy and aggregations of IP- addresses to network addresses, so called subnetting. The proposed routing protocol is capable of deciding the best path to a destination taking into account different possible parameters (e.g., round trip time). The scalability of the 10 protocol is solved by not taking decisions based upon a single end-node identifier; instead the routing decisions are taken based on a network identifier.
