Abstract: A network system uses a management routing instance to route management information between elements involved in management of the system. The system registers each element in the management routing instance when the element comes on line. Based on the management routing instance, the system creates management forwarding tables. The system then uses the management forwarding tables to route management information between the elements. Multiple systems, for example systems connected by a network, may exchange management routing instance information to allow elements in different systems to communicate management information with each other.

Abstract: This application describes techniques for peer-agnostic socket replication to implement graceful failover. An exemplary method to enable non-stop routing includes receiving a packet with a first routing engine of a network device having the first routing engine and a second routing engine configured as a backup routing engine, replicating, before processing the packet at a transport layer, the packet to form a replicated packet, sending the replicated packet from the first routing engine to the second routing engine, receiving, at the first routing engine, an acknowledgement from the second routing engine acknowledging reception of the replicated packet, after receiving the acknowledgment, processing the packet at the transport layer of the first routing engine to extract application-layer data and assemble a routing message, and storing the application-layer data from the processed packet in a socket associated with a routing process of the first routing engine.

Abstract: A network device and a method are provided. The network device may include a plurality of elements and a routing infrastructure. The routing infrastructure may be configured to route network traffic received at the network device, and transfer, among two or more of the elements, packets that include management information related to the routing of the network traffic.
