    Abstract: Techniques for a head-end node in one or more network autonomous systems to utilize a protocol to instantiate services on tail-end nodes. The head-end node can use a service request mechanism that is enabled by the protocol to request service instantiation on the tail-end node without a network operator having to manually configure the tail-end node, or even having access to the tail-end node. Additionally, the protocol may further provide mechanisms to define handling attributes for traffic of the service (e.g., Service-Level Agreement (SLA) parameters, an underlay transport protocol, etc.), service acknowledgement mechanisms for the head-end node to determine that the service was instantiated on the tail-end node, and so forth. In this way, a head-end node can be used to instantiate a service on a tail-end node without a network operator having to have direct access to the tail-end node to manually configure the tail-end node.

    Abstract: Systems, methods, and computer-readable media for fast convergence for virtual ethernet segments in EVPN and PBB-EVPN networks are disclosed. A first provider edge (PE) device can receive one or more advertising messages corresponding to one or more virtual ethernet segments, wherein each of the one or more advertising messages can include a port identifier. The first PE device maintains a table including the one or more virtual ethernet segments and the corresponding port identifier. The first PE device can receive a failure message from a second PE device that identifies a first port on the second PE device, and identifies, based on the table, at least one affected virtual ethernet segment that is associated with the first port. The first PE device can remove any routes that are associated with the at least one affected virtual ethernet segment and trigger mass designated-forwarding election for impacted virtual ethernet segments.

    Abstract: Systems, methods and computer-readable storage media are provided for performing Internet Protocol (IP) address resolution within a network through a control plane or network controller approach. A provider edge (PE) device receives an Address Resolution Protocol (ARP) request message from a locally connected customer edge (CE) device. The PE device transmits the ARP request message to other locally connected CE devices and generates an IP address resolution request message that includes the IP address of a destination CE device. The IP address resolution request message is transmitted to other PE devices within the network. The PE device receives remote adjacency information associated with the destination CE device and transmits an ARP reply message to the locally connected CE device.

    Abstract: Disclosed herein are systems, methods, and computer-readable media for forwarding data in response to a detected local area network failure. In one aspect, a method includes identifying one or more EVPN services in a local area network. In one aspect, the method includes allocating one or more FRR labels, each of the FRR labels corresponding to each of the EVPN services. In one aspect, the method includes broadcasting the FRR labels to a plurality of network appliances of the LAN. In one aspect, the method includes determining one or more EVI-EAD routes associated with the FRR labels. In one aspect, the method includes detecting a LAN failure of one of the plurality of the network appliances. In one aspect, the method includes forwarding incoming data to another one of the plurality of the network appliances in accordance with the determined EVI-EAD routes, in response to detecting the LAN failure.

The head-end node can use a service request mechanism that is enabled by the protocol to request service instantiation on the tail-end node without a network operator having to manually configure the tail-end node, or even having access to the tail-end node. Additionally, the protocol may provide mechanisms to define handling attributes for traffic of the service (e.g., quality of service (QoS) attributes, Maximum Transmission Unit (MTU) settings, etc.), service acknowledgement mechanisms for the head-end node to determine that the service was instantiated on the tail-end node, and so forth. In this way, a head-end node can be used to instantiate a service on a tail-end node without a network operator having to have direct access to the tail-end node to manually configure the tail-end node.
