Abstract
A bit index explicit replication (BIER) packet sending method includes receiving, by a first node in a first BIER domain, a packet from a second node in a second BIER domain, where the packet carries an identifier of the second BIER domain, determining a BIER packet sending policy corresponding to the identifier of the second BIER domain based on the identifier of the second BIER domain and according to a preconfigured BIER packet sending policy, and encapsulating and sending a BIER packet according to the BIER packet sending policy.
Claims20
A method implemented by a first node in a first bit index explicit replication (BIER) domain, wherein the method comprises:
- receiving, from a second node in a second BIER domain, a packet carrying a first identifier of the second BIER domain;
- determining, based on the first identifier and according to a locally configured BIER packet sending policy, a BIER packet sending policy corresponding to the first identifier, wherein the BIER packet sending policy comprises path information corresponding to the first identifier, and wherein the path information identifies a path from the first node to the second node;
- encapsulating the path information into a BIER packet;
- and
- sending, based on the path information, the BIER packet to the second BIER domain.
A first node in a first bit index explicit replication (BIER) domain, wherein the first node comprises:
- a memory configured to store programming instructions;
- and
- a processor coupled to the memory, wherein the programming instructions cause the processor to be configured to:
- receive, from a second node in a second BIER domain, a packet carrying a first identifier of the second BIER domain;
- determine, based on the first identifier and according to a locally configured BIER packet sending policy, a BIER packet sending policy corresponding to the first identifier, wherein the BIER packet sending policy comprises path information corresponding to the first identifier, and wherein the path information identifies a path from the first node to the second node;
- encapsulate the path information into a BIER packet;
- and
- send, based on the path information, the BIER packet to the second BIER domain.
A computer program product comprising computer-executable instructions stored on a non-transitory computer-readable storage medium that, when executed by a processor of a first node in a first bit index explicit replication (BIER) domain, cause the first node to:
- receive, from a second node in a second BIER domain, a packet carrying a first identifier of the second BIER domain;
- determine, based on the first identifier and according to a locally configured BIER packet sending policy, a BIER packet sending policy corresponding to the first identifier, wherein the BIER packet sending policy comprises path information corresponding to the first identifier, and wherein the path information identifies a path from the first node to the second node;
- encapsulate the path information into a BIER packet;
- and
- send, based on the path information, the BIER packet to the second BIER domain.
