摘要： A first router determines a designated router (DR) from a set of routers that are interconnected by a network based on a border gateway protocol (BGP). The set includes the first router. In response to the first router being the DR, the first router forms adjacencies with non-DR routers from the set and distributes reachability advertisements from the set of routers to the non-DR routers in the set. In response to the first router not being the DR, the first router forms an adjacency with the DR. The first router then conveys reachability advertisements to the DR and receives reachability advertisements from the routers in the set via the DR. The DR is determined based on receiving information at the first router indicating an identity of the DR, e.g., configuration information received from a controller, or by electing a DR based on priority values assigned to the routers and advertised in messages transmitted by the routers.

摘要： In certain embodiments, applications employ data packets having a transport header comprising (i) a port number field encoding a vendor private port number and (ii) a tuple field encoding a vendor unique port number comprising a Vendor Organizationally Unique Identifier (OUI) value and a vendor-specified Vendor Port value. This technique for allocating unique port numbers enables vendors to roll out vendor-proprietary applications at will and without involving any external party. This technique enables faster rollout of vendor-proprietary applications over standard transport protocols without needing to standardize or disclose the details of the application in the public domain. Once standardized, e.g., by the Internet Engineering Task Force (IETF), the technique enables any enterprise to roll out its custom/proprietary applications easily.

摘要： Various example embodiments for supporting source routing are presented herein. Various example embodiments for supporting source routing may be configured to support source route compression for source routing. Various example for supporting source route compression for source routing may be configured to support source route compression for source routing based on use of shadow addresses. Various example for supporting source route compression for source routing based on use of shadow addresses may be configured to support source routing of packets based on use of shadow addresses of hops in place of actual addresses of hops to encode source routes within source routed packets, thereby compressing the source routes within the source routed packets and, thus, providing source route compression.

摘要： Various example embodiments for supporting stateful explicit paths are presented herein. Various example embodiments for supporting stateful explicit paths may be configured to support communication of a packet along a path in an Internet Protocol (IP) network from a first node to a second node, wherein the path includes a set of hops, wherein the packet includes a tuple configured to identify the path, wherein the tuple includes a first IP address of the first node, a second IP address of the second node, and a path identifier of the path, wherein the path identifier of the path is a unique identifier assigned to the path, wherein the communication of the packet along the path from the first node to the second node is supported based on state information configured to map the tuple to a next hop in the set of hops of the path.

摘要： A node is configured for deployment in an IP network. The node includes a memory configured to store a first identifier that uniquely identifies the node within the IP network. The node also includes a transceiver configured to receive a first IP packet. The node further includes a processor configured to selectively forward the first IP packet based on whether a first recorded route (RR) in the first IP packet includes the first identifier. Selectively forwarding the first IP packet includes dropping the first IP packet in response to the first identifier being in the first IP packet or pushing the first identifier onto the first RR in the first IP packet in response to the first identifier not being in the first IP packet.
