Abstract: A parsing apparatus includes a packet-type identification circuit and a parser. The packet-type identification circuit is to receive a packet to be parsed, and to identify a packet type of the packet by extracting a packet-type identifier from a defined field in the packet. The parser is to store one or more parsing templates that specify parsing of one or more respective packet types. When the packet type of the packet corresponds to a parsing template among the stored parsing templates, the parser is to parse the packet in accordance with the stored parsing template. When the packet type of the packet does not correspond to any of the stored parsing templates, the parser is to parse the packet using an alternative parsing scheme.

Abstract: A network device includes a memory and a memory management circuit. The memory is to store a shared buffer. The memory management circuit is to estimate respective bandwidth measures for one or more queues used in processing packets in the network device, and to allocate and deallocate segments of the shared buffer to at least one of the queues based on the bandwidth measures.

Abstract: An apparatus for controlling a Shared Buffer (SB), the apparatus including an interface and a SB controller. The interface is to access flow-based data counts and admission states. The SB controller is to perform flow-based accounting of packets received by a network device coupled to a communication network, for producing flow-based data counts, each flow-based data count associated with one or more respective flows, and to generate admission states based at least on the flow-based data counts, each admission state being generated from one or more respective flow-based data counts.

Abstract: A system, switch device, and method of operating a switch device are provided. An illustrative system is disclosed to include a first router block configured to receive a first type of Remote Direct Memory Access (RDMA) packet, a second router block configured to receive a second type of RDMA packet, and a gateway positioned between the first router block and the second router block. The gateway may be configured to translate the first type of RDMA packet received from the first router block for transmission as the second type of RDMA packet by the second router block.

Abstract: A method for communication includes configuring a router to forward data packets in a network in accordance with MPLS labels appended to the packets. A group of two or more of the interfaces is defined as a multi-path routing group in a forwarding table within the router. A plurality of records are stored in an ILM in the router, corresponding to different, respective label IDs, all pointing to the set of the entries in the forwarding table that belong to the multi-path routing group. Upon receiving in the router an incoming data packet having a label ID corresponding to any given record in the plurality, one of the interfaces in the group is selected, responsively to the given record and to the set of the entries in the forwarding table to which the given record points, for forwarding the incoming data packet without changing the label ID.

Abstract: A method in a network element that includes multiple interfaces for connecting to a communication network includes receiving via an ingress interface packets that are not allowed to undergo re-routing and that are addressed to a destination via a first egress interface. The packets are forwarded via the first egress interface when there is a valid path from the first egress interface to the destination. When there is no valid path from the first egress interface to the destination, a second egress interface is selected from a group of multiple egress interfaces that have respective paths to the destination and are assigned to packets for which re-routing is allowed, and the packets are forwarded via the second egress interface until recovering a path to the destination.

Abstract: A communication network includes multiple nodes, which are arranged in groups such that the nodes in each group are interconnected in a bipartite topology and the groups are interconnected in a mesh topology. The nodes are configured to convey traffic between source hosts and respective destination hosts by routing packets among the nodes on paths that do not traverse any intermediate hosts other than the source and destination hosts.

Abstract: A method in a network element that includes multiple interfaces for connecting to a communication network includes receiving from the communication network via an ingress interface a flow including a sequence of packets, and routing the packets to a destination of the flow via a first egress interface. A permission indication for re-routing the flow is received in the ingress interface. In response to receiving the permission indication, subsequent packets of the flow are re-routed via a second egress interface that is different from the first egress interface. Further re-routing of the flow is refrained from, until receiving another permission indication.
