Method and device for providing a minimum congestion flow of ethernet traffic transported over a SDH/SONET network

摘要

A method for providing a minimum congestion flow of Ethernet traffic that is transported through a pipe from a sending point to a receiving point over a synchronous network. The synchronous network comprises network elements, fiber connections connecting the network elements and virtual containers. The transport is managed through a new layer over the synchronous network physical layer, wherein the new layer comprises access points, links of access point pairs and circuits, which are the possible routes for connecting a pair of access points. A delay marker is generated, the a time frame is calculated based on the delay marker, and a congestion of the circuit is estimated based on the time frame.
