Abstract: Various example embodiments for supporting multicast are presented herein. Various example embodiments for supporting stateless multicast may be configured to support stateless multicasting of packets based on encoding of multicast path information within the packets. Various example embodiments for supporting stateless multicasting of packets based on encoding of multicast path information within the packets may be configured to use a recursive scheme of encoding the multicast path information within the packets such that the header that arrives at each node of the multicast path informs the node of the outgoing links over which the packet is to be sent and the headers to be sent on the outgoing links (e.g., each node of the multicast tree is able to recognize each of its outgoing links from the received header and send the appropriate subtree encoding down each of its outgoing links).
