Abstract


With the development of data center applications, the higher and higher demands on the performance of the data center network. The size of the data center network to expand and improve the network performance requirements, special data center network data forwarding needs of the traditional Ethernet forwarding mechanism to face many problems. This paper presents a new Ethernet exchange mechanism for the data center network mTOR, an extension of the existing exchange mechanisms for Ethernet data center network. The mTOR switch reconfigurable configurable features in the data center network switching equipment of a variety of control and packet forwarding policy formulation, load balancing, and multi-path transmission and other special needs of the data center network, and fully The advantage of network topology, so as to achieve the purpose of improve data center network performance at a lower cost. In the field on the basis of the introductory data center network research and design technology for existing data center network research focus, the data center network topology, Ethernet in the data center network technology. This paper describes the design concept of the the mTOR exchange mechanism, technology, address resolution and communication mechanism, and on the basis of this exchange mechanism proposed methods and simulation verification method for data center network load balanced. The main work and innovations include: (1) study the mechanism of exchange in the data center network, Ethernet data center network switching mechanisms are inadequate, the mTOR exchange mechanism, focusing on the the mTOR exchange mechanism design ideas . NetMagic platform proposed by the National Defense Science and Computer Science, Institute of network and information security, the implementation of an mTOR switch, and analyzed the use the mTOR switch the data center network topology and network size. (2) gives the mTOR exchange mechanism from the address rules can use two kinds of address resolution method and its comparison, and gives the mTOR communication mechanism. (3) on the basis of mTOR exchange mechanism, given a data center network traffic load balancing, and use the C language, design, simulation and verification. The simulation and verification of the results showed that, using this approach, the mTOR mechanism can obtain a better load balancing effect. In summary, this paper proposes a new data center network switching mechanism, the data center network research has some theoretical significance and guidance.
