  • Patent number: 10015100
    Abstract: A packet received via a network is stored in a packet memory. Information in a header of the packet is analyzed to determine multiple ports to which the packet is to be forwarded. The packet is read from the packet memory in connection with transmitting the packet via a first port among the multiple ports. Packet data corresponding to the packet is stored in a packet cache different than the packet memory. In connection with forwarding one or more instances of the packet to ports among the multiple ports, the packet data is read, based on information included in a packet descriptor associated with the packet, from the packet cache. Ones of the one or more instances of the packet are forwarded, using the data corresponding to the packet read from the packet cache and without further accessing the packet memory, to respective one or more of the multiple ports.

  • Patent number: 9906632
    Abstract: The network control system of some embodiments implements logical port classifications to implement different features of logical networks onto a physical network. The network control system of some embodiments modifies flow entries at forwarding elements of the physical network to implement the logical network. The network control system classifies logical source and destination ports into disjoint equivalence classes for logical network flows in a virtualized network, and encodes this information in the tunneled traffic carrying the logical flow. The network control system of some such embodiments provides logical port classifications to minimize the necessary flow entries at each forwarding element of the physical network.

  • Patent number: 9900181
    Abstract: The disclosure herein describes a virtual extensible local area network (VXLAN) gateway. During operation, the VXLAN gateway receives, from a physical host, an Ethernet packet destined for a virtual machine residing in a remote layer-2 network broadcast domain that is different from a local layer-2 network broadcast domain where the physical host resides. The VXLAN gateway then determines a VXLAN identifier for the received Ethernet packet. The VXLAN gateway further encapsulates the Ethernet packet with the virtual extensible local area network identifier and an Internet Protocol (IP) header, and forwards the encapsulated packet to an IP network, thereby allowing the packet to be transported to the virtual machine via the IP network and allowing the remote layer-2 network broadcast domain and the local layer-2 network broadcast domain to be part of a common layer-2 broadcast domain.

  • Patent number: 9893981
    Abstract: A multi-hop heterogeneous wireless network is partitioned into a set of subnetworks including a first subnetwork having a first sink node and a second subnetwork having a second sink node. A node forms parts of the first and the second subnetworks and has different modes of operations (MOP) depending on the subnetwork. For example, the node has a first MOP specifying a type of the routing in the first subnetwork and a second MOP specifying a type of the routing in the second subnetwork. The node determines the MOD based on available routing resource of the node that is independent from the subnetwork and based on required routing resource that varies among the subnetworks. The node routs packets in the first subnetwork according to the first MOP and routing packets in the second subnetwork according to the second MOP.
