Bit indexed explicit replication forwarding optimization

Bit indexed explicit replication forwarding optimization

Various systems and methods for performing bit indexed explicit replication (BIER). For example, one method involves receiving a packet at a node. The packet includes a bit string. The node traverses the bit string and selects an entry in a bit indexed forwarding table (BIFT). The entry includes a f...

Zusammenfassung:Various systems and methods for performing bit indexed explicit replication (BIER). For example, one method involves receiving a packet at a node. The packet includes a bit string. The node traverses the bit string and selects an entry in a bit indexed forwarding table (BIFT). The entry includes a forwarding bit mask. Based on the forwarding bit mask and the bit string, the node forwards the packet.
