ABSTRACT:
A system and method for measuring convergence performance in a network are disclosed. In one embodiment, the method includes receiving a plurality of probes at a network device, temporarily storing data from at least a portion of the received probes and deleting at least a portion of the temporarily stored data at regular intervals, and receiving a packet indicating a convergence event and storing data from probes received over a predetermined period.
