Abstract

A method for synchronizing a distributed system is provided. The distributed system includes distributed analyzers. Each analyzer has a synchronization decoder circuit, a medium access controller, and a central processing unit. The distributed system synchronization method comprises receiving multicast information, generating local synchronization signals, receiving control data packets, and beginning processing of monitored data packets. The synchronization decoder circuit receives the multicast information, decodes the multicast information, and responsive to the multicast information, generates local synchronization signals. The decoder synchronization circuit of a first analyzer completes the decoding and the generating in a first time. The first time is adapted to enable the central processing unit of the first analyzer to start and end processing of monitored data packets at a first start time and a first end time. The first start time differs from a start time corresponding to any other analyzer by less than a maximum synchronization time. The first end time differs from an end time corresponding to any other analyzer by less than a maximum synchronization time. The maximum …
