Abstract: 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.

Abstract: Disclosed is a method and network element for providing a safe transport of Ethernet frames over a transport SDH/SONET network. The method is characterized by comprising: at the sending point (AP#0), receiving Ethernet frames to be transported through an Access Point (AP#0); mapping the Ethernet frames into Virtual Containers (VC-X #); assigning (FA) a label to every frame according to a sequence; storing a copy of the sent labeled frames; and at the receiving point (AP#1), receiving the sent labeled frames; re-ordering (FR) the received frames according to the assigned sequence label; updating the value of a pointer according to the label of the last correct frame of the sequence; and outputting the frames through an Access Point (AP#1).
