Data center networks are the backbone of IT infrastructure and cloud services. According to traffic pattern research, a small group of flows transport the vast majority of the bytes and are referred to as elephant flows. Proper management of such traffic ...

Visible Light Communication (VLC) has the potential to provide dense and fast connectivity at low cost. In this paper, we propose a novel VLC-enabled hybrid data center network VBNet. It extends the design of wireless data center networks further into ...

Network congestion has become a performance bottleneck in data center, which needs to be solved urgently. In view of this, this study attempts to apply virtual machine migration to change the position of flow sender or receiver in the network topology ...

3D Fabric jointly uses two strategies for congestion avoidance: flow rate adjustment and path switch. 3D Fabric predicts flow's size and only decelerates large flows in case of light congestion. When the network is heavily congested, it starts to ...

This paper presents HERO, a system for accelerating high performance data center applications by integrating hybrid electrical and optical multicast. We built a prototype and developed a flow-level simulator to evaluate the performance of HERO. ...

Data center network (DCN), a type of network featuring low delays and high bandwidths, exchanges information rapidly through high-performance network switches. Currently, DCN provides various distributed services to satisfy user requirements. However, ...

This document describes a BGP/MPLS IP VPN-based subnet extension solution referred to as "Virtual Subnet", which can be used for building Layer 3 network virtualization overlays within and/or between data centers.

In recent years, the concept of Big Data (BD) analytics has brought rapid changes to the way enterprises conduct business. Everyday more organizations are getting into the cloud of BD users. Due to an influx of data analytic projects, data centers and ...

Data Center (DC), the underlying infrastructure of cloud computing, becomes startling large with more powerful computing and communication capability to satisfy the wide spectrum of composite applications. In a large scale DC, a great number of switches ...

DCell has been proposed for one of the most important data center networks as a server centric data center network structure. DCell can support millions of servers with outstanding network capacity and provide good fault tolerance by only using ...

Large-scale data centers form the infrastructure backbone for supporting cloud computing. The network interconnecting the servers in the data center plays a crucial role in the performance and dependability characteristics of the data centres. With the ...

Data center networks (DCNs) are inherently failure-prone owing to the existence of many links, switches and servers. Many times the failures of the components may be correlated resulting a set of connected components failing together. This correlated ...

Architecture plays an important role in the design of Data Center Networks (DCN). Designs for DCN are to be scalable, robust and efficient. There are many designs proposed in recent years where routing is performed using location information of the ...

ITRI container computer is a modular computer designed to be a building block for constructing cloud-scale data centers. Rather than using a traditional data center network architecture, which is typically based on a combination of Layer 2 switches and ...

The large data center network constructed of only the electronic packet switches consumes large power to provide enough bandwidth for all server pairs. One approach to construct the data center network that provides enough bandwidth with small energy ...

Multi-tenancy and lack of network performance isolation among tenants together make the public cloud vulnerable to attacks. This paper studies one of the potential attacks, namely, low-rate denial-of-service (DoS) attack (or \textit{Shrew} attack for ...

To alleviate the growing concern of energy waste in networked devices, we present PCube, a server-centric data center structure that conserves energy by varying bandwidth availability based on traffic demand. PCube not only supports a low-power mode for ...
