    Abstract: Reducing pool starvation in a switch is disclosed. The switch includes a plurality of egress ports, and a reserved pool of buffers in a shared memory. The reserved pool of buffers is one of a number of reserved pools of buffers, and the reserved pool of buffers is reserved for one of the egress ports. A shared pool of buffers and a multicast pool of buffers are in the shared memory. The shared pool of buffers is shared by the egress ports.

    Abstract: The present invention allows the contents of network-wide broadcast in a first subnetwork to be passed to a second subnetwork even if a router is set to prevent the network-wide broadcast in the first subnetwork from going out of the first subnetwork. In response to the network-wide broadcast in the first subnetwork, a first broadcast relay generates a packet in which a destination address of the network-wide broadcast packet is changed to an address of a second broadcast relay belonging to a second subnetwork, and outputs the address changed packet to the first subnetwork. The second broadcast relay generates, in response to the packet addressed thereto, a second subnetwork-only broadcast as a local broadcast, and outputs it to the second subnetwork. A server of the second subnetwork performs a predetermined process on the broadcast outputted by the second broadcast relay.

    Abstract: Systems and methods for broadcast storm control. A system for broadcast storm control comprises a plurality of ports and a processing module. Each port comprises a counter counting the number of broadcast packets received in a time unit, and a corresponding drop flag set based on the counter value and an ingress rate thereof. The processing module receives a packet from a specific port within the ports, and drops or forwards the packet to at least one of the ports according to the drop flag corresponding to the specific port.

    Abstract: An architecture for a line card in a network routing device is provided. The line card architecture provides a bi-directional interface between the routing device and a network, both receiving packets from the network and transmitting the packets to the network through one or more connecting ports. In both the receive and transmit path, packets processing and routing in a multi-stage, parallel pipeline that can operate on several packets at the same time to determine each packet's routing destination is provided. Once a routing destination determination is made, the line card architecture provides for each received packet to be modified to contain new routing information and additional header data to facilitate packet transmission through the switching fabric. The line card architecture further provides for the use of bandwidth management techniques in order to buffer and enqueue each packet for transmission through the switching fabric to a corresponding destination port. The transmit path of the line card architecture further incorporates additional features for treatment and replication of multicast packets.

    Abstract: In a communication system using multicasting, multicast packets are forwarded through a switch by destination ports after these ports receive the packets. A source node sends the multicast packet to a subset of nodes within the multicast group, which in turn, forward the multicast packet to other subsets of packets within the multicast group that have yet to receive the information. This is continued until all ports within the multicast group have received the information.

    Abstract: A network device includes a memory and a packet forwarding engine. The memory stores a multicast list table, tag descriptor data and layer 2 (L2) encapsulation data. The packet forwarding engine receives a first pointer to an entry in the multicast list table, the entry including a second pointer to the tag descriptor data. The packet forwarding engine utilizes the second pointer to retrieve the tag descriptor data, the tag descriptor data including a third pointer to the encapsulation data. The packet forwarding engine constructs a packet header utilizing the retrieved encapsulation data and appends the packet header to a packet payload for forwarding out of the packet forwarding engine.
