2) after the core cloud receives data request information, search this user's local cloud, and this data request information is sent to this user's local cloud;
3) after this user local cloud is received message, data are sent to the edge cloud of user's login according to the information (sending address, data name etc.) of data request information;
4) after user's service used these data, with the data deletion, again from local cloud moved when using these data next time;
Two, under the situation of network state difference, adopt the data migration method of storing based in advance:
1) user logins the edge cloud and uses cloud service, and system detects in the edge cloud whether this data desired by services is arranged, and changes 5 if having);
2) the edge cloud system forms data request information with this data desired by services and sends to the core cloud;
3) after the core cloud receives data request information, search this user's local cloud, and this data request information is sent to this user's local cloud;
4) after this user local cloud is received message, data are sent to the edge cloud of user's login according to the information (sending address, data name etc.) of data request information;
5) after user's service uses these data, store data in this edge cloud, so that the user uses next time;
Three, when network state constantly changes with extraneous factor, adopt the data migration method of state Network Based:
1) user logins the edge cloud and uses cloud service, and system detects in the edge cloud whether this data desired by services is arranged, and changes 5 if having);
2) the edge cloud system should be served needed formation data request information and be sent to the core cloud;
3) after the core cloud receives data request information, search this user's local cloud, and this data request information is sent to this user's local cloud;
4) after this user local cloud is received message, data are sent to the edge cloud of user's login according to the information (sending address, data name etc.) of data request information;
5) after user's service used these data, current network delay was judged by system, greatly then changeed 6 if postpone), otherwise change 7);
6) store data in this edge cloud, so that the user uses next time, change 8);
7) with the data deletion, when the user uses next time, move again from the local cloud;
8) finish.
In the actual environment, the network between each edge cloud is influenced by various factors, and network performance constantly changes.When the user visited the data of oneself, not good when network condition, its data may cause bigger delay by the network transmission, influence the user and experience.State Network Based carries out the method for data migration according to the network current state, factors such as delay, amount of bandwidth, determine whether the user is stored in these data in the edge cloud of its login, if the network quality at cloud platform place is good, then data are not stored in the edge cloud of user's login, if the user's request data are then directly obtained by network, reduce the dependence to storage resources from user's local cloud.The user is stored in the login cloud with its employed data when the network quality difference, obtains the response time to reduce data, reduces it to the requirement of network state.
