A Hierarchical Routing Mechanism for Service in CPN

Computing power network (CPN) has been proposed to allocate and schedule computing power resources among cloud, network, and edge according to the needs of computing services. CPN can improve the utilization rate of various computing resource pools. However, it brings other challenges that how to transfer data packets based on computing resource information. Since the size of routing table will be too large to store and search with lots of computing information. To solve this problem, we define three computing service types firstly. Then propose a hierarchical routing mechanism for computing services in CPN. Based on this mechanism, CPN can improve data forwarding efficiency and user experience. In the future, we will research standard of computing resource identification to provide more intelligent service for various application.
