    Abstract: A method, network device, and computer program product for network traffic diversion are disclosed. In one embodiment, a method according to the present disclosure includes receiving a frame at a core edge node that is a member of a redundancy group (where the frame comprises network address information and a packet), and determining whether a link is affected by a network failure. The frame was sourced by a remote core edge node that is not a member of the redundancy group, and the network address information indicates that the packet is to be forwarded via the link. In response to the link being affected by the network failure, the method further includes generating a modified frame and forwarding the modified frame to another core edge node. The generating comprises including a redirect label in the modified frame. The another core edge node is another member of the redundancy group.

    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 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.

    Abstract: A method, network device, and computer program product for network traffic diversion are disclosed. In one embodiment, a method according to the present disclosure includes receiving a frame at a core edge node that is a member of a redundancy group (where the frame comprises network address information and a packet), and determining whether a link (to which the core edge node is communicatively coupled) is affected by a network failure. The frame was sourced by a remote core edge node that is not a member of the redundancy group, and the network address information indicates that the packet is to be forwarded via the link. In response to the link being affected by the network failure, the method further includes generating a modified frame and forwarding the modified frame to another core edge node. The generating comprises including a redirect label in the modified frame. The another core edge node is another member of the redundancy group.
