Abstract
A method for deallocating memory in a first network device is described. A multicast packet is received and stored in memory cells. Egress descriptors corresponding to the multicast packet are generated for transmission of the multicast packet. A final count of the egress descriptors is determined. The egress descriptors are processed for transmission of the multicast packet and a value of a signed reference counter corresponding to the multicast packet is updated in a first direction before the final count has been determined and after a copy of the multicast packet has been received by an egress port of the first network device. The value of the signed reference counter is updated in a second direction opposite the first direction by the final count after determination of the final count. The memory cells are deallocated when cumulative first direction updates are equal to the second direction update.
