Abstract

A switch encapsulates incoming information using a header, and removes the header upon egress. The header is used by both distributed ingress nodes and within a distributed core to facilitate switching. The ingress and egress elements preferably support Ethernet or other protocol providing connectionless media with a stateful connection. Preferred switches include management protocols for discovering which elements are connected, for constructing appropriate connection tables, for designating a master element, and for resolving failures and off-line conditions among the switches. Secure data protocol (SDP), port to port (PTP) protocol, and active / active protection service (AAPS) are all preferably implemented. Systems and methods contemplated herein can advantageously use Strict Ring Topology (SRT), and conf configure the topology automatically. Components of a distributed switching fabric can be geographically separated by at least one kilometer, and in some cases by over 150 kilometers.
