Cloud computing service coordination center: Classification Management is carried out in the cloud service that cloud computing edge service provider provides, user's service request is analyzed fractionation, current service is provided or combines multiple services into new service according to user's request according to user's request to offer the user.
Use with reference to the local service of Fig. 3 is described in detail; Local service refers to that service that the user uses is that Edge Server by its place provides.The user submits own required service to by terminal, and demand for services sends to the edge service manager, and service managerZ-HU searches whether provide this service in local Edge Server.If this service is provided, service managerZ-HU returns to terminal with the address of service, the corresponding service of address of service visit that terminal is returned according to service managerZ-HU.Below at three kinds of dissimilar Service Sources, its use is described in detail:
Software service: cloud computing offers user with software with service manner by network, and from user's angle, they no longer need to be concerned about the installation and upgrade of software, does not also need disposable purchase software license.But pay according to the actual operating position of rental service.User's step when using local software service is as follows:
1) user submits required software function to interface;
2) interface mails to service management module in the edge cloud with this information;
3) service management module changes 4 according to software function information searching related software if find); Do not change 5 if find);
4) service management module returns to the interface with the software interface address, and the interface is presented to the user with the form of icon with the address of service, changes 6);
5) result who will not find returns to the interface, and the interface shows " not having this service item " information to the user;
6) user uses service.
In the whole reciprocal process, the user submits its required software function to and checks that last lookup result (if this function is provided, presents to the user in the icon mode.If this function is not provided, then prompting " not having this service item ") be visible.
The storage resources service: cloud computing provides unlimited storage resources service to the user in theory.Therefore, system reasonably stores and backs up according to factors such as user's data sizes automatically.Whole process is transparent to the user.
Data storages: when the user produces data in the process of using service, system's storage and back up this data, the Service Management step is as follows, as Fig. 4:
1) user virtual machine produces storage request M1 (user ID, size of data), after memory allocation and recycling module receive request, to not using memory module request memory space M2 (storage size);
2) do not use memory management module to return to memory allocation and recycling module M3 (memory address);
3) transmission message M4 (user ID, size of data, memory address) arrived usage space after memory allocation and recycling module received memory space, recorded this message.
When the user deleted data, system can reclaim storage resources automatically, and the relevant backup of deletion.Its step is as follows, as Fig. 5:
1) user determines a certain data of deletion, and system produces data removal request M1 (user ID, size of data), sends to memory allocation and recycling module;
2) after memory allocation and recycling module are received deletion message, send M2 (user ID, size of data) to using memory module to search address data memory;
3) use memory module to find after the memory address of deletion data to memory allocation and recycling module transmission message M3 (user ID, size of data, memory address), deleted this record simultaneously;
4) memory allocation and recycling module send message M4 (memory address) to not using memory module after receiving the address of deleting data.
Computational resource service: can provide unlimited computational resource for the user on the cloud computing theory.Cloud computing system provides the computational resource service of " as required pay " to the user, and the user can select the modes of two kinds of use computational resources according to the requirement difference of task to real-time when using the computational resource Processing tasks.Therefore, system provides two kinds of policy selection when the user uses the computational resource service:
(1) in the response time of regulation, finishes the calculating of service;
(2) use a certain amount of computational resource to finish the calculating of service.
System distributes rational computational resource according to user's selection and the amount of calculation of service that the user uses to the user.Assigning process as shown in Figure 6.
When 1) user used the service that needs a large amount of computational resources, the system prompt user selected calculative strategy, and (1) responds in official hour.(2) use the computational resource of regulation to calculate this service;
2) system judges that the user selects, if choosing (1) then changes 3); Choosing (2) then changes 4);
3) user selects to finish the work at the appointed time calculating, and system calculates required computational resource according to the amount of calculation of acceptable response time of user and task.Change 6);
4) user's computational resource of selecting to fix calculating of finishing the work, the size and corresponding response time of several computational resources for reference of system prompt;
5) user's size of computational resource of selecting to finish the work;
6) system assignment computational resource.
The distribution of computational resource and recovery: this process is to user transparent.The computational resource size required according to system, computational resource allocation and recycling module are distributed to the corresponding resource of user according to the overall operating position of resource, use in resource simultaneously and create a record in the module.
Use with reference to the user's cross-domain services of Fig. 7 is described in detail; Under the edge cloud computing environment, when certain single edge cloud can't satisfy user's demand, the then mutual cooperation of other edge clouds under the coordination of core cloud provided service for the user jointly.

Service management module is submitted this software asks information among the A;
2) after edge cloud A service management module receives solicited message, in the software resource management, search relevant soft
Part if find related software, then changes 7), if do not find related software then to change 3);
3) do not find related software in the software resource administration module, then send out to core cloud computing service management module
Refer to the information of searching of asking;
4) after core cloud computing service management module receives search request, search this software service by any block edge
Cloud provides, and then changes 5 if find); Do not change if do not find then;
5) suppose that core cloud computing service management module finds edge cloud B this software service is provided, then should be soft
The part request message is routed in this edge cloud;
When 6) this edge cloud receives search request, search this software, the address of this software service is sent to edge cloud A;
7) receive the software service address after, the portal module with this address transition be one the service icon represent to the user; The user brings into use service by icon, changes 9);
8) for finding the related software service, system sends the information of " not having related service " to the user;
9) finish.
The search procedure of this software service is to user transparent.From user perspective, have only the user to submit to required service relevant with the user with last lookup result (find then and present to the user with the icon form, do not find then to send and do not find information).
The storage resources service: cloud computing system provides unlimited storage resources service for the user.It is transparent to the user that storage resources is served whole process, and the user need not be concerned about the memory address that its data are concrete, backup etc.Therefore, there are following two kinds of situations to need the collaborative demand that could satisfy the user of a plurality of edges cloud, as Fig. 9:
1) in order to guarantee safety of user data, the edge cloud computing system backs user data in the different edge clouds according to certain strategy;
2) when the memory space of certain single edge cloud can not satisfy user's storage demand, needing other edge clouds to work in coordination with provides memory space to satisfy user's demand.
Polygon edge cloud cooperation with service step is as follows:
1) virtual machine produces data, and system-computed goes out the size that will store data, and this information passes to edge cloud memory management module;
2) memory management module judges whether that according to the storage size of data assistance of other edge clouds of needs finishes, if need then change 4);
3) if do not need other edge clouds to assist, then memory management module distributes corresponding memory space, changes 6);
