Path computation method, node, storage medium and computer program product

A path computation method, applied to a head node, the path computation method comprising:

• acquiring virtual networks and Cyclic Queuing and Forwarding (CQF) scheduling parameters supported by nodes, wherein each of the nodes supports at least one CQF scheduling parameter;
• acquiring a target binding relationship, wherein the target binding relationship is a binding relationship between a target virtual network and a target CQF scheduling parameter, the target virtual network is one of virtual networks supported by the head node, and the target CQF scheduling parameter is one of CQF scheduling parameters supported by the head node;
• determining a plurality of target nodes and a plurality of target links belonging to the target virtual network according to the target binding relationship and the virtual networks and the CQF scheduling parameters supported by the nodes;
• and
• calculating a target path to a tail node in the target virtual network according to the plurality of target nodes, the plurality of target links, and the target CQF scheduling parameter.
