US 12,003,410 B2 · Method and apparatus for establishing forwarding path, and computer-readable storage medium

Abstract

A method and an apparatus for establishing a forwarding path, the method including obtaining, by a first network node, path information of a to-be-established forwarding path, where the path information comprises an identifier of a network node on the forwarding path and a transmission resource requirement that needs to be allocated by the network node to the forwarding path, and sending a path establishment request packet based on the path information, where a packet header of the path establishment request packet comprises the path information, and where the path establishment request packet triggers the network node to allocate a transmission resource to the forwarding path based on the transmission resource requirement.

Dependent claims

A method for establishing a forwarding path, comprising:

obtaining, by a first network node, path information of a to-be-established forwarding path, wherein the path information comprises an identifier of a network node on the forwarding path and a transmission resource requirement that needs to be allocated by the network node to the forwarding path;
and
sending a path establishment request packet based on the path information, wherein a packet header of the path establishment request packet comprises the path information, wherein the path information is carried in a segment routing header (SRH) of a path establishment request packet, and wherein the path establishment request packet triggers the network node to allocate a transmission resource to the forwarding path based on the transmission resource requirement.

An apparatus, comprising:

one or more processors;
and
a non-transitory computer readable medium having a computer program stored thereon for execution by the one or more processors to establish a forwarding path and act as a first network node, the computer program including instructions to:
obtain path information corresponding to a to-be-established forwarding path, wherein the path information comprises an identifier of a network node on the forwarding path and a transmission resource requirement that needs to be allocated by the network node to the forwarding path;
and
send a path establishment request packet based on the path information, wherein a packet header of the path establishment request packet comprises the path information wherein the path information is carried in a segment routing header (SRH) of a path establishment request packet, and wherein the path establishment request packet triggers the network node to allocate a transmission resource to the forwarding path based on the transmission resource requirement.

An apparatus, comprising:

one or more processors;
and
a non-transitory computer readable medium having a computer program stored thereon for execution by the one or more processors to establish a forwarding path and act as a second network node, the computer program including instructions to:
receive a path establishment request packet, wherein a packet header of the path establishment request packet comprises path information, wherein the path information is carried in a segment routing header (SRH) of a path establishment request packet, and wherein the path information comprises an identifier of a network node on the forwarding path and a transmission resource requirement that needs to be allocated by the network node to the forwarding path;
allocate a transmission resource to the forwarding path based on the path information;
and
send the path establishment request packet.
