Fig. 1 is the schematic flow sheet of a kind of Mobile load balancing method of the present invention.
Embodiment
Mobility load balance system of the present invention, comprising: distributed store module, List Generating Module, balance module and feedback module.
The function of above-mentioned each module is described below in conjunction with a kind of Mobile load balancing method of the present invention.
Refer to shown in Fig. 1, Mobile load balancing method of the present invention mainly adopts the mode of distributed store to solve the problem of load balancing, namely computational resource is stored in respectively in different servers or service cluster, each service node only stores wherein part of service, this just needs user when request service, needs the service node that locking is corresponding.The implementation of this service is through service mapping and reaches, and each service request is according to the Service Instance pointed by request, and user side first asks for the specific service address of this Service Instance to mapping services (map).Then, directly service is obtained by this address.
Specifically, key step of the present invention comprises: (1) distinguishes computational resource by distributed store module, and different computational resources is stored in different server steps respectively; (2) step of the dynamic routing list of each computational resource corresponding server address is generated by List Generating Module; (3) by balance module when receiving the service request of mobile terminal, the step of the server address that computational resource is corresponding needed for dynamic routing list determination described request; And (4) address of being determined by balance module by feedback module is sent to the step of mobile terminal.
Wherein, the balance module appointment that mDNS can be adopted to translate pattern, mProxy, mStatic agreed schema etc. realize service node.The mDNS pattern of translating refers to that service need not specify concrete service node in a program, and the Communication Control through mobile terminal translates to concrete service node.MProxy proxy mode refers to that service can realize address locking through proxy server.MStatic agreed schema refers to the method automatically pointing to certain node in service array according to information such as ID.
Above-mentioned dynamic routing of the present invention is for the service of dispersion response, for cloud dish, each cloud dish can be registered in unified index center the address of service of oneself, when needs obtain certain concrete cloud dish data, obtains concrete address of service by search index center.
