The Computing Power Network (CPN) deeply integrates originally dispersed and heterogeneous computing resources from the cloud

edge

and terminals

meeting the stringent requirements of emerging services for real-time data processing and efficient distribution. The identity resolution service serves as a fundamental prerequisite for enabling data storage and retrieval to support these functionalities. The key challenge lies in constructing an efficient data indexing mechanism to respond to data retrieval and storage requests

regardless of how data is cached within the CPN. Therefore

based on the coordinate indexing method CNR

a low-latency identifier resolution mechanism was proposed for computing power networks. By constructing a triangulation graph (DT) graph based on geographic routing

any query request from computing nodes was responded to within the virtual space maintained by CNR

significantly reducing the path length for cross-server data retrieval and thereby achieving efficient identifier resolution services. Experiments showed that compared to existing solutions

the identifier resolution mechanism using CNR reduced lookup path length by 41.61% and response time by 57.19%.
