MULTI-LEVEL REPLICATION COUNTER STORAGE DEVICE FOR MULTICAST PACKET PROCESSING AND RELATED METHOD FOR MANAGING MULTICAST PACKET PROCESSING

摘要

A multi-level replication counter storage device for multicast packet processing includes a first-level storage device and a second-level storage device. The first-level storage device stores a plurality of first count values associated with a same cell data of a first multicast packet required to be broadcasted to a plurality of multicast targets, wherein a sum of the stored first count values is equal to a number of multicast targets to which the same cell data of the first multicast packet is not broadcasted yet. The second-level storage device stores a second count value which is adjusted based on the first count values to indicate whether a multicast operation of the same cell data of the first multicast packet is accomplished.

1. A multi-level replication counter storage device for multicast packet processing, comprising:
a first-level storage device, configured to store a plurality of first count values associated with a same cell data of a first multicast packet required to be broadcasted to a plurality of multicast targets, wherein a sum of the stored first count values is equal to a number of multicast targets to which the same cell data of the first multicast packet is not broadcasted yet; and a second-level storage device, configured to store a second count value which is adjusted based on the first count values to indicate whether a multicast operation of the same cell data of the first multicast packet is accomplished.
