| Summary: | 碩士 === 國立中正大學 === 通訊工程研究所 === 103 === With the growth of Cloud Service,Data Centers have become an efficient and promising infrastructure for supporting data storage.Data Centers increase the size of data dramatically.However, the traditional tree structure Data Centers network topologies will be unable to support the large data flows.Therefore, Some new network architectures are presented, such as Fat-Tree,BCube and VL2.However, new network architectures have some problems.Because of new network architectures have many redundant paths.When Data Centers run a routing protocol such as Shortest Path Routing or Minimum Spanning Tree,it will be unable to use redundant paths to achive load balancing.In order to increase the transmission capacity and high survivability.Because of Server uses ARP Protocol to learn the MAC addresses of the destination IP addresses.the growth of Server will cause a broadcast storm.Alos, the Switch will increase the size of forwarding tables dramatically.Nevertheless, the Switch can’t handle a large number of Servers and the main limitation of current data center architectures is scalability.Therefore, this paper presents the solution to using MPTCP increasing Cloud network bandwidth and using VLAN based on creating multiple Link-Disjoint paths in Cloud Data Center network.MPTCP can use different VLAN paths to effectively disperse traffic and improve the transmission efficiency. Finally, in order to reduce the ARP broadcast packet and the size of forwarding tables, the integration of SDN designs a new APR packet management method.
