In order to realize the optimization of multi database environment index of cloud, it needs to construct index topology, and robustness of the proposed control, depth first traversal mechanism in cloud computing environment index design method based on robust topology. Constructing adaptive robust multilayer routing detection protocol, build cloud computing database the index under the load balance topology control node distribution model, through the transmission cost function of intra cluster and inter cluster index, quantitative equation to build cloud computing node topology multi database environment, quantitative analysis of the quantitative recursive equation, realize the accurate positioning of topological node deployment, and uses the depth first traversal mechanism and the minimum hop count routing method to design robust topology structure, improve the ability of cloud computing database multilayer index environment. Experimental results show, this method is used to design index topology, which improves the efficiency of database multi index, improves the timeliness of database access and the accuracy of data retrieval.

INTRODUCTIONSWith the development and application of stochastic network information technology, the main form of cloud computing gradually developed into modern network information computing and processing. Cloud computing is a computing concept in recent years, the basic idea is to use the idle network, distributed in other local resources, such as computer hardware resources, software resources, centralized intelligent scheduling and information processing of network information resources. In the cloud computing grid space, cloud computing grid space resources needed for automatic deployment management, dynamic expansion, according to need, the effective integration of cloud data center resources, cloud computing environment database multi index control, improve the utilization rate of cyber source cloud computing improve access and scheduling capability, cloud storage database, research in cloud computing environment index topology robust control problem, improve access to database and data Scheduling capability [1].
