Abstract
A network management system for determining the synchronization between two streams of packets transmitted in a transport network measures throughput variations for each of the streams of packets and determines the synchronization by comparing the variations.
Claims12
A network management system for determining the synchronization between two streams of packets transmitted in a transport network, said system including:
- means for measuring throughput variations for each of said two streams of packets;
- and
- means for determining the synchronization by comparing said throughput variations, wherein said throughput variations for each of said two streams of packets comprise variations of the ratio between the total size of the packets and the total time intervals between two successive packets of said stream of packets, and further wherein said variations of the ratio are calculated over a time window, and a time interval between said two successive packets of said stream of packets is variable.
