Research On Resource Control Strategy Of BOSS Network In Data Center Based On Multi Core Optical Fiber

With the upcoming of 5G era and development of Internet big data technology,it is more obvious that the data center has shown its great impact on internet ecology.However,the emerging technologies and the surging service patterns pose great challenges to the interconnect networks of data centers.Considering the energy consumption,bandwidth occupation and deployment costs,optical interconnection become the main solution of the data centers interconnection with replacing the traditional electric-switch based interconnection networks,which has been a key trend of the next-generation data center interconnection networks.Under the requirements of large capacity,low latency and resourceefficient bearing,the multi-core fiber based optical burst networks can greatly improve the network capacity and services scheduling flexibility,but it also brings more complicated transmission channel environment,the common network resource allocation strategies are hard to guarantee the transmission performance.Therefore,this work jointly considered crosstalk among fiber cores and burst collision problems in burst optical slot switching(BOSS)based data center interconnection networks and research on channel scheduling strategies.The main works and contributions are as following:Firstly,based on the traffic patterns in data centers,this work proposed a multi-core fiber based BOSS architecture for data center interconnection networks.Then,comprehensively considering the service bandwidth,latency and duration time requirements,the crosstalk-aware based BOSS multi-core fiber channel scheduling strategy was proposed to minimize the burst packet loss under the limited optical network resources and node switch resources constraints and demonstrated under different switch architectures.Simulations results revealed that the proposed switch architectures and channel scheduling algorithms are promising to realizing the goal of low packet loss rate under different switch architectures,network traffic loads and topologies settings.Secondly,this work designed and developed an optic-electric integrated burst switch control platform,including interface data structure and control plane module.The experiments demonstrations of services path establishments have shown that the developed control plane can cooperate the data plane to achieve configuration and administration of the above proposed channel scheduling algorithm results,which is represented through front-end display of management platform.
