Apparatus, method of determining transmission path and computer-readable storage medium

An apparatus comprising a first node, and the first node comprises:

• at least one processor coupled with a memory, the memory having computer readable instructions stored thereon that when executed by the at least one processor cause the apparatus to:
• determine a first candidate path group, wherein the first candidate path group comprises at least one first candidate path,
• a destination node of the at least one first candidate path is the second node, when the source node of the at least one first candidate path is the first node, and
• the destination node of the at least one first candidate path is the first node, when the source node of the at least one first candidate path is the second node;
• select a first path from the at least one first candidate path according to a preset first rule based on node information of each of the first candidate paths in the first candidate path group, wherein the node information comprises a node identifier (ID) and at least an ingress port number of a node connected to the at least one first candidate path or an egress port number of the node connected to the first candidate path;
• and
• determine that the first path is the transmission path, in response to the source node of the first path is the first node;
• and
• determine that a second path is the transmission path, in response to the source node of the first path is the second node, wherein the second path is a reverse path of the first path.

A non-transitory computer-readable storage medium comprising computer readable instructions stored thereon that, when executed by a processor, cause an apparatus to:

• determine a first candidate path group, wherein the first candidate path group comprises at least one first candidate path,
• a destination node of the at least one first candidate path is the second node, when the source node of the first candidate path is the first node, and
• the destination node of the at least one first candidate path is the first node, when the source node of the first candidate path is the second node;
• select a first path from the at least one first candidate path according to a preset first rule based on node information of each of the first candidate paths in the first candidate path group, wherein the node information comprises a node identifier (ID) and at least an ingress port number of a node connected to the at least one first candidate path or an egress port number of the node connected to the first candidate path;
• and
• determine that the first path is the transmission path, in response to the source node of the first path is the first node;
• and
• determine that the second path is the transmission path, in response to the source node of the first path is the second node, wherein the second path is a reverse path of the first path.
