In the novel computing power network architecture, each network element has control and forwarding capabilities and also has computing capabilities, and computing nodes are deployed in the network, so that computing power can be widely distributed in cloud, edge, end and middle network elements, and the computing power is fused in the network. In the novel network architecture, the control surfaces of the network elements and the computing nodes are pulled through, so that the defect of current computing power fusion can be overcome, and the response to movement and network change can be timely carried out. In the architecture of the computing power network, each computing node runs a proxy (Kube-proxy) of the open source container orchestration system kubernetes, which is a load balancer inside a kubernetes (K8 s) cluster, and can monitor the change situations of services (services) and endpoints (endpoints) in an application program interface (application program interface, API) server (API SERVER), and configure load balancing for the services through firewalls (iptables) and the like. In general, a computing system provides more services, and when a terminal device is used as a computing node in a cluster, for example, as a service provider or a service requester, the terminal device needs to monitor changes of an endpoint irrelevant to self-request or service provision in real time, so that air interface control signaling overhead is high.
