Abstract
A method for configuring a network, and a network configured according to such method, are provide in which a communication links laid out in a ring in a metropolitan area are partitioned into link segments, and managed according to a spanning tree protocol. The switches are configured to establish unique, mesh or tree type network configurations suitable for application to communication media arranged to support ring-based protocols. The method is used for connecting communication links arranged in a plurality of rings, which traverse a plurality of collocation sites in a metropolitan area. The method comprises configuring switches in the plurality of collocation sites to partition rings in the plurality of rings into a plurality of link segments providing point to point paths between switches at collocation sites in the plurality of collocation sites. The switches and link segments are managed according to a spanning tree protocol. In one embodiment of the invention, the configuring of switches includes allocating a first set of the link segments as a first ring and a second set of the link segments as a second ring, breaking the first and second rings by blocking transmission on…
