摘要： Techniques are provided for forwarding packets via an intermediate network device. A packet comprising a destination MAC address is received at a first port of a network device having a plurality of bi-directional ports. A second port of the network device to which the packet should be forwarded is identified through the use of at least an approximate ingress table at the first port comprising a plurality of compressed destination MAC addresses each having an associated egress port, and the packet is forwarded to the second port. At the second port, a subsequent network device to which the packet should be forwarded is identified through the use of an exact egress table at the second port including exact destination MAC addresses each associated with a network device connected to the second port, and the packet is forwarded to the subsequent network device.

摘要： A system and method are provided that support a routing using a tree-like or graph topology that supports multiple links per node, where each link is designated as an Up, Down, or Lateral link, or both, within the topology. The system may use a segmented MAC architecture which may have a method of re-purposing MAC IP addresses for inside MACs and outside MACs, and leveraging what would normally be the physical signaling for the MAC to feed into the switch.

摘要： Methods and systems for routing frames are provided. A system includes an initiator operationally coupled to a first switch that is coupled to a second switch. The first switch includes a plurality of ports for sending and receiving frames and includes a routing table that identifies a port identifier steering table based on an area field of a frame header of a frame received by the first switch. The first switch also includes a plurality of port identifier tables, where each port identifier table is associated with a unique area field and identifies a same port of the first switch for a plurality of area fields. The second switch stores an area steering table with port identification information associated with an area field of a frame header of a frame received by the second switch and a same port of the second switch is assigned to multiple area fields.

摘要： In one embodiment, a reassign command is received for reassigning a first node identified by a first global identifier (GID) from a first context identified by a first context ID (CID) to a second context identified by a second CID, the first and second contexts representing first and second linked lists, respectively. A walk-the-chain (WTC) command having the first GID and the first CID is issued to a first linked list processor. The first linked list processor is configured to access one or more nodes of the first context in an attempt to dequeue the first node from the first context. An enqueue command having the first GID and the second CID is issued to a second linked list processor. The second linked list processor is configured to insert the first node to the second context. The first and second linked list processors are cascaded to form a pipeline.

摘要： A method, system, and/or computer program product steers Internet Protocol (IP) packet fragments. A switch receives a first IP packet fragment that contains a 3-tuple in its header. In response to determining that the first IP packet fragment is not a lead packet fragment in the series of IP packet fragments, the first IP packet fragment is pushed onto a data stack. The switch subsequently receives a second IP packet fragment that contains a 5-tuple, which includes the 3-tuple from the first IP packet fragment plus a source port and destination port used by the second IP packet fragment. The 3-tuple is mapped to the 5-tuple in a fragmentation table, thus enabling both the first IP packet fragment and the second IP packet fragment to be steered to the destination port to which the second IP packet fragment is being sent.

摘要： A network switch includes a look-up engine for obtaining associated data in response to a header portion of a packet and an interlinked network processor such as a RISC for performing a processing function on the header portion or the associated data. Both look-up engine and the network processor may modify a destination port bitmask. The network processor may implement additional packet header processing required for replication or server load balancing.

摘要： A physical host executes a virtual machine monitor (VMM) that instantiates a source virtual machine (VM). In response to the VMM receiving from the source VM a packet specifying a first destination address of a destination VM and a second destination address of a default gateway, the VMM determines whether the packet can be communicated to the destination VM without the packet being routed by the default gateway. In response to the VMM determining that the packet can be communicated to the destination VM without the packet being routed by the default gateway, the VMM forwards the packet to the destination VM such that the packet bypasses routing by the default gateway.

摘要： The present invention enables the coupling and decoupling of multiple processing devices to a network without disrupting the network. In an embodiment, the invention provides a switch having a network port and several initiator ports each configured for coupling to a processing device. The switch is configured to route data from the network port to the initiator ports and from the initiator ports to the network port. A management agent facilitates operation of the switch by processing port initializations, replying to device registration requests, and processing predetermined unsolicited discovery commands. During operation, the management agent enables configuration changes caused, for example, by the coupling and/or decoupling of processing device to initiator ports.

摘要： The invention discloses a method and system for realizing transmission of message between an extended processor and a switch chip. The switch chip amends the destination MAC of the received first message to be transmitted to the extended processor as the first destination MAC, and then transmit the first message to the extended processor, wherein the first destination MAC corresponds to the service physical port of the switch chip for receiving the first message; the extended processor can resolve the first destination MAC to learn that the first message comes from the service physical port. The method and system of the invention can realize transmission of message between the extended processor and the switch chip.
