Method, device and computer program product for path optimization

An electronic device, comprising:

• at least one processing unit;
• at least one memory coupled to the at least one processing unit and storing instructions executable by the at least one processing unit, the instructions, when executed by the at least one processing unit, causing the device to perform acts comprising:
• obtaining, at an edge node of a network including a plurality of nodes between the edge node and a destination node, locations and performances of one or more nodes from among the plurality of nodes in the network based on responses of the one or more nodes to at least one request from the edge node;
• determining, by the edge node, performance indices associated with the one or more nodes based on the locations and the performances of the one or more nodes and a service level objective (SLO), a performance index indicating a difference between a performance of a respective node and the SLO;
• and
• determining, by the edge node, based on the locations of the one or more nodes and the performance indices, a target path for delivering a packet from the edge node to the destination node.

A computer program product that is tangibly stored in a non-transitory computer storage medium and comprises machine-executable instructions which, when executed by a device, causing the device to perform steps of:

• obtaining, at an edge node of a network including a plurality of nodes between the edge node and a destination node, locations and performances of one or more nodes from among the plurality of nodes in the network based on responses of the one or more nodes to at least one request from the edge node;
• determining, by the edge node, performance indices associated with the one or more nodes based on the locations and the performances of the one or more nodes and a service level objective (SLO), a performance index indicating a difference between a performance of a respective node and the SLO;
• and
• determining, by the edge node, based on the locations of the one or more nodes and the performance indices, a target path for delivering a packet from the edge node to the destination node.
