Abstract
A path identity allocation method, system, and apparatus, a device, and a storage medium are provided, and belong to the field of communication technologies. According to the method, a forwarding node on a path receives a PCEP packet, so that when determining that path identification information of the path is unavailable, the forwarding node performs, based on indication information in the PCEP packet, an operation associated with the path identification information, for example, determines, based on indicated content, that the forwarding node reallocates a path identity, or requests the control node to reallocate a path identity.
Claims30
A method, performed by a forwarding node on a path, the method comprising:
- receiving a path computation element protocol (PCEP) packet, wherein the PCEP packet comprises path identification information identifying the path and indication information associated with the path identification information, wherein the indication information is located in a reserved field in the PCEP packet or a flags field in the PCEP packet;
- and
- determining that the path identified by the path identification information is unavailable, and performing, based on the indication information, an operation associated with the path identification information.
A method, performed by a control node, the method comprising:
- generating a path computation element protocol (PCEP) packet, wherein the PCEP packet comprises path identification information identifying a path and indication information associated with the path identification information, the indication information is located in a reserved field in the PCEP packet or a flags field in the PCEP packet, and the indication information indicates to a forwarding node on the path to perform, based on the indication information when the forwarding node determines that the path identified by the path identification information is unavailable, an operation associated with the path identification information;
- and
- sending the PCEP packet to the forwarding node.
An apparatus, wherein the apparatus is configured as a forwarding node on a path, and the apparatus comprises:
- at least one non-transitory memory storing instructions;
- and
- at least one processor coupled to the at least one non-transitory memory, wherein the instructions, when executed by the at least one processor, cause the apparatus to:
- receive a path computation element protocol (PCEP) packet, wherein the PCEP packet comprises path identification information identifying the path and indication information associated with the path identification information, and the indication information is located in a reserved field in the PCEP packet or a flags field in the PCEP packet;
- determine that the path identified by the path identification information is unavailable;
- and
- perform, based on the indication information, an operation associated with the path identification information.
An apparatus, wherein the apparatus is configured as a control node, and the apparatus comprises:
- at least one non-transitory memory storing instructions;
- and
- at least one processor coupled to the at least one non-transitory memory, wherein the instructions, when executed by the at least one processor, cause the apparatus to:
- generate a path computation element protocol (PCEP) packet, wherein the PCEP packet comprises path identification information identifying a path and indication information associated with the path identification information, the indication information is located in a reserved field in the PCEP packet or a flags field in the PCEP packet, and the indication information indicates to a forwarding node on the path to perform, based on the indication information when the forwarding node determines that the path identified by the path identification information is unavailable, an operation associated with the path identification information;
- and
- send the PCEP packet to the forwarding node.
