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

摘要

Disclosed is 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 at least one SDH/SONET network, the at least one SDH/SONET network comprising network elements, fiber connections connecting the network elements and SDH/SONET virtual containers, the transport being managed through a new layer over SDH/SONET network physical layer, the new layer comprising Access Points, links of Access Point pairs and circuits, namely the possible routes for connecting a pair of Access Points. The method further comprising: generating a delay marker at the network element of the sending point; transmitting the delay marker to the network element of the receiving point and back to the network element of the sending point through at least one Circuit; calculating the time frame for the sending point network element to receive back the delay marker; and estimating the congestion of the Circuit according to the time frame for receiving back the delay marker. <IMAGE>
