摘　　要：近年来,提出的以服务器为中心的新型数据中心网络互连结构部分程度地解决了传统树型结构面临的性能瓶颈和可扩展性难题,同时出现了以集装箱为基本模块构建超大规模的数据中心.然而,如何设计模块之间的互连结构,确保数据中心网络具有高可扩展性、模块之间具有高带宽是一个非常具有挑战性的问题.以BCube为代表的新型数据中心网络,能够将数千台服务器互连在一个集装箱内,且对各种典型流量模式提供较高的带宽.提出了一种常量度数的模块之间的互连结构MDCent.MDCent基于BCube结构进行模块内服务器互连,利用模块内大量未被使用的上行端口,在各个模块保持常量度数的情况下,能够保证模块之间具有高可扩展性,同时模块之间具有较高的带宽.A fundamental goal of data-center networking is to efficiently interconnect a large number of servers with low equipment cost while keeping high network bandwidth. Some server-centric data center networking structures are proposed to tackle the performance bottleneck and the extensibility problems that the traditional tree-based networking schemes are born with. Shipping-container-based data centers are introduced as building blocks for constructing mega-data centers. However, it is a challenge how to interconnect those containers to make sure that the network among the containers has both high scalability and high performance. As a new server-centric network architecture, BCube is able to interconnect thousands of servers into a container and provide high bandwidth for typical traffic patterns. This paper presents a networking architecture among containers called MDCent, which is based on BCube to interconnect servers inside a container. MDCent makes the network among containers have both high scalability and performance on condition that each container makes use of a lot of unused up-link ports and has a fixed degree.
