    Abstract: Techniques are disclosed for avoiding sending network traffic through a backup network device when an active network device is operational. An example device is configured to receive a first address resolution protocol (ARP) request from an active network device and a second ARP request from a backup network device. The device is also configured to, in response to receiving the first ARP request and the second ARP request, send a first ARP response to the active network device.

    Abstract: Techniques are disclosed for session-based routing within Open Systems Interconnection (OSI) Model Layer-2 (L2) networks extended over Layer-3 (L3) networks. In one example, L2 networks connect a first client device to a first router and a second client device to a second router. An L3 network connects the first and second routers. The first router receives, from the first client device, an L2 frame destined for the second client device. The first router generates an L3 packet comprising an L3 header specifying L3 addresses of the first and second routers, a first portion of metadata comprising L2 addresses for the first and second client devices, and a second portion of metadata comprising L3 addresses for the first and second client devices, and forwards the L3 packet to the second router. The second router recovers the L2 frame from the metadata and forwards the L2 frame to the second client device.

    Abstract: Techniques are disclosed for session-based routing within Open Systems Interconnection (OSI) Model Layer-2 (L2) networks extended over Layer-3 (L3) networks. In one example, L2 networks connect a first client device to a first router and a second client device to a second router. An L3 network connects the first and second routers. The first router receives, from the first client device, an non-session-based L2 frame destined for the second client device. The first router forms an L3 packet comprising an L3 header specifying L3 addresses of the first and second routers and a protocol selected based on an L3 service for the L2 frame, a payload comprising the L2 frame, and metadata comprising a session identifier distinctly identifying the L2 frame, and forwards the L3 packet to the second router. The second router recovers the L2 frame from the payload and forwards the L2 frame to the second client device.

    Abstract: Techniques are described for a router providing metric-based multi-hop path selection. For example, a first router of a plurality of routers receives a plurality of network performance metrics for a plurality of links interconnecting the plurality of routers. The plurality of links form a plurality of multi-hop paths through the plurality of routers to a service instance. The router determines, based on the plurality of network performance metrics for the plurality of links, an end-to-end performance of each of the plurality of multi-hop paths. The router selects a multi-hop path over which to forward traffic associated with the session based on the end-to-end performance of each of the plurality of multi-hop paths and one or more performance requirements for a service associated between a session between a client device and the service instance. The router forwards the traffic to the service instance along the selected multi-hop path.

    Abstract: Techniques are disclosed for session-based routing of multipoint Open Systems Interconnection (OSI) Model Layer-2 (L2) frames of an L2 network extended over Layer-3 (L3) networks. In one example, L2 networks connect a source device to an ingress router and receiver devices to egress routers. An L3 network connects the ingress and egress routers. The ingress router receives, from the source device, a multipoint L2 frame destined for the receiver devices. The ingress router forms, for each egress router that is connected to at least one multipoint receiver device, a unicast L3 packet for the L2 frame and forwards the unicast L3 packet to the egress router. Each egress router generates, in response to receiving the unicast L3 packet, the multipoint L2 frame and forwards, to the receiver devices, the multipoint L2 frame.
