    Abstract: A universal network interface controller (UNIC) is provided for interfacing a host computer to a switch fabric, a packet network, or both. The UNIC includes ingress transmit logic designed to transmit switch fabric data in memory associated with the host computer to a switch fabric. The UNIC further includes egress receive logic designed to receive switch fabric data from the switch fabric to store the received switch fabric data in the host memory associated with the host computer. As an option, the ingress transmit logic may be further designed to transmit packet network data in memory associated with the host computer to a packet network, such as Ethernet, and the egress receive logic may be further designed to receive the packet network data from the packet network and to store the received switch fabric data and the received packet network data in the host memory associated with the host computer.

    Abstract: A system and method can support multi-homed routing in a network environment, which can be based on InfiniBand architecture using a fat-tree or a similar topology. The system can provide an end node that is associated with a switch port on a leaf switch in a network fabric. Then, the system can perform routing for each of a plurality of ports on the end node, and ensure that the plurality of ports on the end node take mutually independent paths.

    Abstract: A communication method in a network operating in accordance with a standard that allocates a given number of bits m for layer-2 addressing of nodes in the network. The method includes accepting at a layer-2 switch in the network an assignment to one or more nodes in the network of respective layer-2 extended addresses, each including n=m+k bits, k>0. A given data packet is received at the switch for forwarding. The given data packet includes a layer-2 destination address and a layer-3 destination address in accordance with the standard. The layer-3 destination address includes t bits, t≧k. The given data packet is forwarded from the switch to one of the nodes by reading from the given data packet and combining the layer-2 destination address and k bits from the layer-3 destination address so as to reconstruct the n bits of the extended layer-2 address of the one of the nodes.

    Abstract: A distributed virtual chassis comprises scaled-out fabric coupler (SFC) boxes. Each SFC box has fabric ports and a cell-based switch fabric for switching cells associated with a packet among the SFC fabric ports of that SFC box. Distributed line cards (DLCs) include switching DLCs and an appliance DLC (A-DLC). Each switching DLC has network ports. Each switching DLC and A-DLC has DLC fabric ports. Each switching DLC and A-DLC is connected to each of the SFC boxes. The A-DLC provides an upper layer service for packets arriving on the network ports of the switching DLCs. To forward a packet to the A-DLC, a switching DLC divides the packet into cells and distributes the cells among the SFC boxes. The SFC boxes forward the cells to the A-DLC, and the A-DLC reassembles the packet from the cells and provides the upper layer service to the packet.

    Abstract: A method and apparatus are described to provide shared switch and cache memory. The apparatus may comprise a message switch module, a cache controller module, and shared switch and cache memory to provide shared memory to the message switch module and to the cache controller module. The cache controller module may comprise pointer memory to store a plurality of pointers, each pointer pointing to a location in the shared switch and cache memory (e.g., point to a message header partition in the shared switch and cache memory). If there is a corresponding pointer, a memory read response may be sent to the requesting agent. If there is no corresponding pointer, a write data request may be sent to a corresponding destination agent and, in response to receiving the requested data, a pointer to the stored data in the pointer memory may be provided.
