Background

Under the development trend of cloud computing and edge computing, computing power of many different scales can be distributed at different distances close to users in future society, and various personalized services are provided for the users through a global network. From a billion-level intelligent terminal, to a billion-level home gateway all over the world, to thousands of edge clouds with computing power brought by future MECs (mobile electronic commerce) in each city, and to dozens of large cloud data centers DC in each country, a huge amount of ubiquitous computing power is formed, and the development trend of computing and network deep fusion is formed.

As shown in fig. 1, computing resources in the network are merged into each corner of the network, so that each network node can become a provider of the resources, and a user's request can be satisfied by calling the nearest node resource and is not limited to a specific node, thereby avoiding waste of connection and network scheduling resources.

However, the conventional network only provides a pipeline for data communication, is based on connection, is subject to a fixed network addressing mechanism, and often cannot meet the requirements of higher and more strict QoE (Quality of Experience).

In addition, with the development of micro-services, a traditional client-server mode is deconstructed, an application deconstruction function component on a server side is distributed on a cloud platform and is uniformly scheduled by an application program interface gateway (API gateway), dynamic instantiation can be achieved as required, service logic in the server is transferred to the client side, the client side only needs to care about a computing function and does not need to care about computing resources such as the server, a virtual machine and a container, and therefore the function of serving as one server is achieved. However, existing networks do not meet the computational resource allocation needs of future networks.
