Method and network element for a safety transport of ethernet frames over a transport SDH/SONET network

摘要

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; reordering (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).
