Abstract

A system for multicast switching for distributed devices may include an ingress node including an ingress memory and an egress node including an egress memory, where the ingress node is communicatively coupled to the egress node. The ingress node may be operable to receive a portion of a multicast frame over an ingress port, bypass the ingress memory and provide the portion to the egress node when the portion satisfies an ingress criteria, otherwise receive and store the entire frame in the ingress memory before providing the frame to the egress node. The egress node may be operable to receive the portion from the ingress node, bypass the egress memory for the portion and provide the portion to the first egress port when an egress criteria is satisfied, otherwise receive and store the entire multicast frame in the egress memory before providing the multicast frame to an egress port.

First claim

What is claimed is:

1. A method for multicast switching for distributed devices, the method comprising:
receiving a multicast frame at an ingress node of a network device, wherein the ingress node comprises an ingress buffer dedicated to the ingress node and the ingress node is associated with an ingress switching policy;
determining, based on a classification of the multicast frame, whether the ingress switching policy associated with the ingress node indicates that the multica…
