Improved transport Ethernet traffic over a transport network SDH / SONET.

摘要

A method for treating Ethernet frame signals in a SDH / SONET network (Synchronous Digital Hierarchy / Synchronous Optical NETworkc = Synchronous Digital Hierarchy / Synchronous Optical Network), SDH / SONET network elements or nodes and fiber connections comprising that connecting the network elements, the method being characterized by the step of defining a new layer / network (NETS = network of Ethernet Transport over SDH / SONET = network Ethernet Transport over SDH / SONET) between SDH / SONET and Ethernet, for gestionartratar Ethernet signals over the SDH / SONET network, using the new layer / network (NETS) resources SDH / SONET network in such a way that optimizes the services provided and the performances with reference to this specific type of transport; wherein the step of defining a new layer / network (NETS) comprises the steps of: defining at least two access points (AP) of Ethernet, namely Ethernet interfaces at the network boundary SDH / SONET where Ethernet signals can access / leave the SDH / SONET network; defining a Link as a pair of Ethernet Access Points providing a point-to-point connection; for any pair of Ethernet Access Points, defginir corresponding Circuits, namely all possible routes connecting the pair of Access Points through the SDH / SONET network; and dDividir each circuit in ducts, namely a sequence of smaller segments.
