Abstract:
A method for transmitting jitter information in a network, wherein a connection for a call is established from a source node to a destination node through a plurality of nodes and a frame counter is located at each of the nodes, the method comprising the steps of:(a) detecting propagation delays and corresponding mismatch delays between neighboring node pairs, delay bounds at each of the nodes, and a frame size of the connection, wherein each neighboring node pair includes an upstream node positioned toward the source node and a downstream node positioned toward the destination node and the corresponding mismatch delay results from the mismatch in time slot boundaries between an upstream node and a downstream node;(b) synchronizing and activating the frame counters, each frame counter being located at a corresponding node, based on the propagation delays and the corresponding mismatch delays between the neighboring node pairs, the delay bounds at each of the nodes, and the frame size of the connection; and(c) servicing a cell from the source node to the destination node through each node based on the value of the corresponding frame counter.
