Edge cloud is the best fi t point of the operator’s"cloud+5G"dual engine strategy.Edge network is the key to realize cloud network planning and build the operator’s"connection+computing"core capability.The traditional access network of operators has prominent problems such as cloud network fragmentation

segmented access to the cloud and complex networking

which is diffi cult to meet the requirements of agile delivery of edge services.Through in-depth analysis of the edge cloud business characteristics and technical architecture

this paper studies the construction practice of mainstream cloud providers in the standard industry

studies the edge network construction idea based on cloud pop network

innovatively puts forward the reform of cloud network integration planning

design

construction and delivery process

and constructs a double-layer accelerated network architecture of overlay and underlay integration based on cloud Po P unified network and business anchor

explore the methods of realizing L3 sinking and elastic capacity expansion of the new spine-leaf metropolitan area access network

and realize the edge network capability of integrated and agile delivery of"cloud+network+application".
