Data center networks today face exciting new challenges in supporting cloud computing and other data-intensive applications. In conventional DCNs, different types of traffic are carried by different types of networks, such as Ethernet and Fibre Channel. Typically, Ethernet carries data traffic among servers in LANs, and Fibre Channel connects servers and storages in storage area networks. Due to the existence of multiple networks, the network cost, power consumption, wiring complexity, and management overhead are often high. The concept of a converged DCN is therefore appealing, carrying both types of traffic in a single converged Ethernet. Recent standards have been proposed for unified data center bridging (DCB) Ethernet and Fibre Channel over Ethernet (FCoE) protocols by the DCB Task Group of IEEE and the T11 Technical Committee of INCITS. In this article, we give a survey of the standards and protocols on converged DCNs, focusing mainly on their motivations and key functionalities. The technologies are discussed mainly from a practical perspective and may serve as a foundation for future research in this area
As cloud computing [1] has emerged as a promising technology to serve various computing needs, data centers have attracted much attention in both industry and academia because they are the essential facilities to support cloud computing. Data centers are often massive infrastructures containing servers, storage, networks, power systems, cooling systems, monitoring systems, and so on. Today, many major companies such as Amazon, Google, Facebook, and Microsoft deploy data centers at strategic locations, providing services such as IT infrastructure
outsourcing, web search, and social networking.The performance of a data center is often determined by
the efficiency of the data transportation inside the data center. The communication network inside the data center
is often referred to as the data center network (DCN), which allows users, servers, and storage devices to communicate with each other. Traditionally, a DCN uses different networks to carry different types of traffic, as shown in Fig. 1a. Typically, Ethernet carries the traffic between servers in LANs, and Fibre Channel (FC) carries the traffic between storage devices and servers in storage area networks(SANs)
