Abstract: Various example embodiments for supporting stateless multicast in communication networks are presented. Various example embodiments for supporting stateless multicast in communication networks may be configured to support stateless multicast in multi-domain packet distribution networks. Various example embodiments for supporting stateless multicast in communication networks may be configured to support stateless multicast in multi-domain packet distribution networks which may be based on Internet Protocol (IP). Various example embodiments for supporting stateless multicast in a multi-domain packet distribution network may be configured to support multicast of packets based on use of internal multicast packets for multicast communication of the multicast packets within sub-domains of the multi-domain packet distribution network and use of external multicast packets for unicast communication of the multicast packets across or between sub-domains of the multi-domain packet distribution network.

Abstract: Various example embodiments for supporting communication of inter-card control messages in a router chassis are presented herein. The communication of an inter-card control message in a router chassis may be performed using a data packet sent over a switch fabric of the router chassis. The data packet may include a payload and a data packet header, where the payload includes the inter-card control message and the data packet header includes an indication that the data packet includes the inter-card control message. The inter-card control message may be sent over the switch fabric indirectly using a data packet protocol header encapsulating the payload and a switch fabric header encapsulating the data packet protocol header. The inter-card control message may be sent over the switch fabric directly using a switch fabric header encapsulating the payload.

Abstract: A first router transmits a first message including information identifying a first set of transport layer protocols supported by the first router. The first router receives a second message including information identifying a second set of transport layer protocols supported by a second router. A common transport layer protocol is selected from a subset of transport layer protocols that are common to the first and second sets of transport layer protocols. The first router then establishes a border gateway protocol (BGP) session with the second router over the common transport layer protocol. The first message is unicast to the second router or broadcast/multicast over a plurality of links to a plurality of routers that includes the second router. In some cases, the common transport layer protocol is selected by the router having a higher priority, based on preferences, or a combination thereof.
