Abstract: 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.

Abstract: A first router receives a targeted message that is unicast from a second router that is multiple network hops away from the first router. The first router establishes a transport layer connection between the first router and the second router in response to the targeted message. The first router then establishes a session over the transport layer connection. The session operates according to a border gateway protocol (BGP). In some cases, the targeted message includes information such as an IP address of the first router, a transport layer parameter, an ASN associated with the second router, and an identifier of the routing protocol associated with the second router. A frequency of targeted messages exchanged by the first and second routers is reduced in response to a duration of the session increasing and turned off if the duration exceeds a threshold duration.

Abstract: Various example embodiments for supporting secure communications via secure sessions in communication systems are presented. Various example embodiments for supporting secure communications via secure sessions in communication systems may be configured to support mechanisms in a session layer protocol which enable communications of any communication protocol at any communication protocol layer to be transported over a session layer session (e.g., tunneling any data link protocol, any network layer protocol, any transport layer protocol, and/or any application layer protocol transparently over the session layer protocol), which enable multiple communications of one or more communication protocols of one or more communication protocol layers to be transported over a single session layer session (e.g., multiplexing two or more data streams of any data link protocol, any network layer protocol, any transport layer protocol, and/or any application layer protocol transparently over the session layer protocol), and so forth.

Abstract: A software defined networking (SDN) controller or routers in a network determine unicast paths from an ingress router to egress routers from the network based on quality-of-service (QoS) metrics for links between routers of the network. A subset of the unicast paths is associated with a multicast flow based on one or more QoS criteria for the multicast flow. A router pushes a label stack onto a packet of the multicast flow. The label stack includes labels that identify the subset of the unicast paths. The packet including the label stack is multicast through the network to the egress routers. Routers that receive the multicast packet selectively modify the label stack in the packet based on the labels that identify the subset of the unicast paths. The routers selectively forward the packet based on the labels.

Various example embodiments for supporting an in-band control plane may be configured to support an in-band control plane in a Multiprotocol Label Switching (MPLS) network. Various example embodiments for supporting an in-band control plane in an MPLS network may be configured to support an in-band control plane in an MPLS network by supporting exchange of control protocol packets of control protocols as MPLS packets, such that the control protocol messaging is in-band along the MPLS data plane itself. Various example embodiments for supporting an in-band control plane in an MPLS network may be configured to support an in-band control plane in an MPLS network by supporting communication of MPLS packets that encapsulate control protocol messages of control protocols with an MPLS label which indicates that the payloads of the MPLS packets carry the control protocol messages of the control protocols.
