ABSTRACT:
In a telecommunications network, segments along a telecommunications connection causing data corruption or data degradation can be detected and precisely identified through a segment performance monitoring technique. The segment performance monitoring technique involves the generation, transmission, and analysis of specialized data packets which traverse a telecommunications connection node by node. At each node, a value for one or more segment performance characterization factors is accumulated based upon a predefined block of user-assigned data packets. Degradation of the data caused by any segment along the telecommunications connection can be determined, in part, by comparing the value for the one or more segment performance characterization factors to one or more performance characterization factor values generated by a source node.
