    Abstract: A method is provided in one example embodiment and includes receiving a request to create a path through a network, wherein the path originates on a first network device and terminates on the second network device; identifying a first controller associated with the first network device, wherein the first controller proxies control plane functions for the first network device; identifying a second controller associated with the second network device, wherein the second controller proxies control plane functions for the second network device; and computing the path using the first controller as a source and the second controller as a destination. The first controller installs the computed path on the first network device and the second controller installs the computed path on the second network device.

    Abstract: In one embodiment, a particular PE device of a plurality of multi-homing PE devices between a core network and a local network determines a subset of traffic for which the particular PE device is responsible. The particular PE also establishes, with itself as root, a multicast tree within the local network for underlay multicast groups. Traffic received at the particular PE from the core network is admitted into the local network only if the core traffic corresponds to the subset of traffic for which the particular PE device is responsible (and mapped into one of the underlay multicast groups for which the particular PE device is the root). Also, multicast traffic received at the particular PE from the local network is forwarded into the core network only if the multicast traffic corresponds to the subset of traffic for which the particular PE device is responsible.

    Abstract: In one embodiment, one or more point-to-point (P2P) services are established between attachment circuits on provider edge (PE) devices in a computer network, and each of the one or more P2P services (e.g., Virtual Private Wire Service, VPWS) are associated with an Ethernet virtual private network (E-VPN) Ethernet Auto-Discovery (A-D) route, where links between the PE devices and customer edge (CE) devices are configured as Ethernet interfaces with Ethernet tagging. As such, the Ethernet A-D route may then be exchanged for each P2P service attachment circuit, and forwarding can be performed on the one or more P2P services without performing a media access control (MAC) address lookup and without performing MAC learning.

    Abstract translation: 在一个实施例中，在计算机网络中的提供商边缘（PE）设备上的附接电路之间建立一个或多个点对点（P2P）服务，并且所述一个或多个P2P服务（例如，虚拟专线服务， VPWS）与以太网虚拟专用网（E-VPN）以太网自动发现（AD）路由相关联，其中PE设备和客户端（CE）设备之间的链路被配置为具有以太网标记的以太网接口。 因此，可以为每个P2P服务附接电路交换以太网A-D路由，并且可以在一个或多个P2P服务上执行转发，而不执行媒体访问控制（MAC）地址查找，而不执行MAC学习。

    Abstract: In one embodiment, a source transmits one or more data packets to a destination over a primary pseudowire (PW). When a device on the primary PW detects a downstream failure of the primary PW, and in response to receiving one or more data packets from a source from the failed primary PW, the device adds a loopback packet identifier to the one or more received data packets, and returns the one or more data packets with the loopback packet identifier to the source upstream on the primary PW. Accordingly, in response to receiving the data packet returned with a loopback packet identifier from the primary PW (in response to the downstream failure), the source retransmits the one or more data packets to the destination over a backup PW.

    Abstract translation: 在一个实施例中，源将主要伪线（PW）发送一个或多个数据分组到目的地。 当主PW上的设备检测到主PW的下游故障时，并且响应于从故障主PW接收到来自源的一个或多个数据分组，该设备向一个或多个接收的数据分组添加环回分组标识符 并将具有环回分组标识符的一个或多个数据分组返回到主PW上游源。 因此，响应于从主PW（响应于下游故障）接收到以环回分组标识符返回的数据分组，源通过备份PW将一个或多个数据分组重传到目的地。

    Abstract: A system and method for advertising out-of-resources (OOR) conditions for entities, such as nodes, line cards and data links, in a manner that does not involve using a maximum cost to indicate the entity is “out-of-resources.” According to the technique, an OOR condition for an entity is advertised in one or more type-length-value (TLV) objects contained in an advertisement message. The advertisement message is flooded to nodes on a data network to inform them of the entity's OOR condition. Head-end nodes that process the advertisement message may use information contained in the TLV object to determine a path for a new label switched path (LSP) that does not include the entity associated with the OOR condition.

    Abstract: An example method for instantiating a network using a network function virtualization infrastructure (NVFI) pod in a network environment is provided and includes receiving a request to instantiate a logical network topology in the NFVI pod that includes a pre-selected set of interconnected pre-configured hardware resources, the abstract network topology including a virtual network function (VNF) forwarding graph (FG), distilling the VNF FG into various interconnected VNFs, deploying various VNFs of the VNF FG to a plurality of virtual machines, and instantiating the network topology on appropriate hardware resources in the NFVI pod. In specific embodiments, the pre-selected set of interconnected pre-configured hardware resources includes a plurality of compute servers, a plurality of controller servers, a set of network resources, and a plurality of storage resources. It may also include a high performance virtual switch operating in a user space of respective memory elements of a plurality of servers.
