Because the gateway deployment is a dual-network state, generally an enterprise local area network + a public network, but because the public network IP of the enterprise equipment is not fixed, private network communication is adopted, and meanwhile, the communication efficiency can be improved.
As shown in fig. 2, an edge-side enterprise P2P center cluster is established, an edge gateway center service list and an alternative center service gateway list of the enterprise are determined, and an edge gateway center service master node and an alternative node are determined. The edge gateway central service refers to that k gateways selected according to a central service selection rule are used for synchronizing cloud information in many edge gateways in enterprise privatization network deployment, and edge management autonomy can be completed when a cloud network is not communicated.
Specifically, the method comprises the following steps:
step one, enterprises deploy respective edge gateways to automatically connect with a central server for activation.
And step two, the edge gateway central service determines an edge gateway central service cluster list and an alternative central service gateway list, and sends the lists to each edge gateway of the enterprise.

The cloud service refers to a system for edge gateway management, drive management and drive file management on a cloud server. The gateway list refers to the information list of ip, port, access user name, password and the like of the gateway. A private network center service is provided with a cluster of 3 nodes, so that the information is ensured to be consistent with the cloud platform service; the alternative service means that when a node in the central service is unavailable, the node is automatically registered to the central service, and the reliability of the cluster is ensured.
The edge gateway center service periodically synchronizes the cloud edge information.
In this embodiment, as shown in fig. 3, the following steps are specifically adopted:

Suppose the file summary text information is: x, the cached file information of the p2p is X.p2p; the storage content of the cache file is as follows: assuming that the file size is fsize, in Kb; the cache file marks that the number of bytes downloaded is n ═ fsize/10.0, rounding up, that is: when fsize is divided by 10 completely, n is fsize/10; when fsize cannot divide by 10, n is (fsize/10) + 1; the cache file is designed to be that the number of bytes stored integrally is n +1, the highest bit is a mark bit, if each slice is downloaded, the highest bit is 1, otherwise, the highest bit is 0; the algorithm for determining the highest result r is as follows: sequentially taking n bits from the lowest bit to perform bitwise AND, returning the r value to be 0 when r appears as 0 for the first time, and returning the r value after the operation from the lowest bit to the nth bit is completed; the data structure is as follows:
A. downloaded completed data structure
Highest order n n-1 n-2 ... 7 6 5 4 3 2 1
