Publication number: 20240106887Abstract: Server selection for improving latency with an instance of a service is disclosed. Generally, lower core latency is preferrable. Core latencies can be related to a physical distance between endpoints connected via a communication pathway, such as a first server and second server connected via network equipment. A geographic distance between endpoints can be different from a topological distance of a communication pathway between endpoints. Endpoints, e.g., servers, can be ranked based on topological distance. The ranking can be communicated to service provider equipment to enable selection of a server based on a corresponding ranking of the server. Selection of an endpoint based on topological distance can enable improved latency in comparison to selecting an endpoint based on geographical distance. Improved latency can result in an improved quality of experience for a user of a service supported by an endpoint selected based on topological distance.Type: ApplicationFiled: September 27, 2022Publication date: March 28, 2024Inventors: Zhengye Liu, Yali Liu, Jin Wang, Raghvendra Savoor
