Abstract—The design of the data center network that interconnects the massive number of servers is very important to ensure the agility and robustness of the data center to meet the requirements of the applications. In response to this challenge, the research community have begun exploring novel interconnect topologies including FatTree, DCell, BCube, HyPaC, etc.

A flexible and high-performance data center network topology2016 •
In order to meet the insatiable demands for cloud-based services, today’s data centers may have hundreds of thousands of servers. During the past decade, many topologies have been proposed to interconnect a large number of servers in a data center network. However, existing topologies face several challenges including the rigid structure, high network cost, and packet relay overheads on servers. In this paper, we propose a novel switch-centric network topology, called DCCube, which offers many desirable properties for data center networking. DCCube is a flexible structure because, given the switches degree and the network diameter, it is possible to construct different structures with different number of connected servers, bisection bandwidth and network cost. Furthermore, DCCube can accommodate a large number of servers with high bisection bandwidth, low cost, small diameter and desirable path diversity. By comparing with existing data center network topologies, we show that DCCube achieves both high performance and low network cost. We also design both minimal and non-minimal routing algorithms for the proposed topology. Simulation results reveal that non-minimal routing is preferred for unbalanced traffic patterns.

Data centers are becoming increasingly popular for their flexibility and processing capabilities in the modern computing environment. They are managed by a single entity (administrator) and allow dynamic resource provisioning, performance optimization as well as efficient utilization of available resources. Each data center consists of massive compute, network and storage resources connected with physical wires. The large scale nature of data centers requires careful planning of compute, storage, network nodes, interconnection as well as inter-communication for their effective and efficient operations. In this paper, we present a comprehensive survey and taxonomy of network topologies either used in commercial data centers, or proposed by researchers working in this space. We also compare and evaluate some of those topologies using mininet as well as gem5 simulator for different traffic patterns, based on various metrics including throughput, latency and bisection bandwidth.

The increasing trend to migrate applications, computation and storage into more robust systems leads to the emergence of mega data centers hosting tens of thousands of servers. As a result, designing a data center network that interconnects this massive number of servers, and providing efficient and fault-tolerant routing service are becoming an urgent need and a challenge that will be addressed in this thesis. Since this is a hot research topic, many solutions are proposed like adapting new interconnection technologies and new algorithms for data centers. However, many of these solutions generally suffer from performance problems, or can be quite costly. In addition, devoted efforts have not focused on quality of service and power efficiency on data center networks. So, in order to provide a novel solution that challenges the drawbacks of other researches and involves their advantages, we propose to develop new data center interconnection networks that aim to build a scalable, cost...

Abstract A fundamental challenge in data center networking is how to efficiently interconnect an exponentially increasing number of servers. This paper presents DCell, a novel network structure that has many desirable features for data center networking. DCell is a recursively defined structure, in which a high-level DCell is constructed from many low-level DCells and DCells at the same level are fully connected with one another. DCell scales doubly exponentially as the node degree increases.

Building scalable data centers, and network devices that fit within these data centers, has become increasingly hard. With modern switches pushing at the boundary of manufacturing feasibility, being able to build suitable, and scalable network fabrics becomes of critical importance. We introduce Stardust, a fabric architecture for data center scale networks, inspired by network-switch systems. Stardust combines packet switches at the edge and disaggregated cell switches at the network fabric, using scheduled traffic. Stardust is a distributed solution that attends to the scale limitations of network-switch design, while also offering improved performance and power savings compared with traditional solutions. With ever-increasing networking requirements, Stardust predicts the elimination of packet switches, replaced by cell switches in the network, and smart network hardware at the hosts.
