Research And Application Of Load Balancing Technology In Semantic Switch

With the rapid development of the Internet,data on the single node type current processing function can not meet the growing requirements of large data processing.Multi-node type data centralized processing to provide distributed computing method has become the increase in cloud computing environment data processing performance is one of the effective methods.Semantic switch is used in the data center network server infrastructure,with arbitrary extension of data processing functions,multiple semantic switch assembly used for forming based on the semantics of a new generation of smart cloud computing platform for efficient distributed data provided for calculating a kind of effective solution.The application of load balancing technology in semantic exchange is an effective way to realize the distributed computing of the new generation intelligent cloud computing platform.Based on the analysis of semantic exchange and software architecture of Intelligent Cloud Computing,the thesis studied for single node and multi node semantic switches in the load balancing technology for single node semantic switch proposed polling method,response speed and load balance method based on the distribution of weight.And these methods greatly improve the power of organization and semantic data processing and the run stability of a single node switch.As for the multi-node cluster for multiple semantics of switches(pool service),this thesis proposed a minimum number of links between nodes method,inter-node load weight adaptive load-balancing method and load balancing node holding a session,which effectively improved the efficiency of the service load balancing pool semantic switch,improved data exchange process in the organization of security,so that it's able to maintain long-term efficient,stable,safe and controlled work.Combining virtualization technology into elastic compute pool for flexible extension service node,improved resource utilization service pool.Based on the study of load balancing methods,the thesis gives the software design and implementation of semantic switch load balancing module.These studies has a certain theoretical and practical value for the study of semantic switch load balancing,and promote the process of achieving semantic switch.In addition,this thesis provides a theoretical and practical support for the new distributed computing technology,which can help to promote research and development of intelligent cloud computing.
