Abstract: A device receives policy information associated with configuring a network, and receives network information associated with the network. The device determines, based on the network information, that the policy information is associated with implementation of egress peer engineering techniques for the network, and identifies, based on the network information, a first set of destinations of the network that satisfies a particular threshold bandwidth. The device assigns costs and bandwidths to the first set of destinations based on the policy information, and monitors bandwidth utilization by the first set of destinations. The device processes information associated with the first set of destinations, with a model, based on the bandwidth utilization and based on the egress peer engineering techniques, to generate a first set of ranked destinations, and causes traffic in the network to be managed based on the first set of ranked destinations and the policy information.

Abstract: In general, techniques are described for performing packet loss measurement in a distributed data plane. In one example, a local router includes a plurality of forwarding units that implement a distributed data plane. First and second forwarding units may switch layer two (L2) packet data units (PDUs) between the local router and a remote router using a virtual path. The first and second forwarding may unit may increment, in response to processing any PDU of the PDUs for the virtual path, respective counters stored by the first and second forwarding units. The first and second forwarding units may update, based on the respective counters, a loss-measurement packet (LMP). For instance, the first forwarding unit, upon updating the LMP, may internally forward the LMP to the second forwarding unit. The second forwarding unit, upon updating the LMP, may send the LMP to the remote router.

Abstract: A device receives network information associated with a network and server information associated with one or more server devices, wherein the network is associated with a network device and the one or more server devices. The device generates, based on the network information and the server information, an encapsulation profile for a tunnel encapsulation path and a route profile for the tunnel encapsulation path. The device provides, to the network device, the encapsulation profile for the tunnel encapsulation path and the route profile for the tunnel encapsulation path, and provides, to the one or more server devices, the encapsulation profile for the tunnel encapsulation path. The tunnel encapsulation path is provided between the network device and the one or more server devices, via the network, based on the encapsulation profile for the tunnel encapsulation path and the route profile for the tunnel encapsulation path.

Abstract: A network device selects a primary source for multicast traffic and a secondary source for the multicast traffic, where the multicast traffic is provided to endpoint devices communicating with a network, and where the primary source and the secondary source are redundant sources. The network device provides a first join request that includes information that causes a primary path to be provided from the primary source through the network. The network device provides a second join request that includes information that causes a secondary path to be provided from the secondary source through the network. The network device receives the multicast traffic from the primary source via the primary path and the secondary source via the secondary path, and provides the multicast traffic received from the primary source to the endpoint devices. The network device prevents the multicast traffic received from the secondary source from reaching the endpoint devices.

Abstract: A network device is provided in a private virtual local area network (VLAN). The network device receives a packet on one of multiple private VLAN ports of the network device, and assigns a classified VLAN signature to the packet. The network device also assigns a primary VLAN signature to the packet, and stores a media access control (MAC) address and the classified VLAN signature of the packet in a single MAC address table.
