Energy efficiency is becoming increasingly important in the operation of networking infrastructure, especially in enterprise and data center networks. Researchers have proposed several strategies for energy management of networking devices. However, we need a comprehensive characterization of power consumption by a variety of switches and routers to accurately quantify the savings from the vari...

Delayand Disruption-Tolerant Networking (DTN) is an emerging area of networking research that will benefit from real-world trials and testbeds. We describe a week long DTN trial carried out during the summer of 2009 in the Laponia area of Northern Sweden that involved the provision of basic email and web services to users who were 57km distant from any power or networking infrastructure. The tr...

In today’s world the business environment is experiencing the dramatic change in the field of computer networking. Global competitions have forced traditional and non-traditional organization to be more aggressively influence the technology for competitive advantage. But many organization have struggled to manage the changes in order accelerate time to market with new technology. Equipment manu...

This paper proposes a framework based on an active networking approach to efficiently link Quality-of-Service (QoS) descriptions from an application point of view with an underlying heterogeneous IP networking infrastructure. The main goal is to provide building blocks that cooperate to sense the availability of and deploy distinct QoS capabilities in order to accomplish adaptive end-to-end ser...

Optical networking technologies have been over the last two decades reshaping the entire telecom infrastructure networks around the world. As network bandwidth requirements increase, optical communication and networking technologies have been moving from their telecom origin into the enterprise. For example, today in data centers, all storage area networking is based on fiber interconnects with...

The main goal for this article is to compare performance penalties when using KVM virtualization and Docker containers for creating isolated environments for HPC applications. The article provides both data obtained using synthetic tests (High Performance Linpack) and real life applications (OpenFOAM). The article highlights the influence on performance of major infrastructure configuration opt...

Worldwide, electrical grids are developing into smart grids. To ensure reliability, robustness and optimized resource usage, these grids will need to rely heavily on modern information and communication technologies. To support the achievement of these goals in communication networks, we evaluated the possibility of using software-defined networking (SDN) infrastructure based on OpenFlow, to pr...

This paper concerns concerns the impact that pervasive computing will have on how we design networking. We identify the pressure points where pervasive computing will push current approaches to their limits, covering both technical and business implications. We use a broad definition of communications technology, to include not only infrastructure equipment and services, but also communications...

Mobile ad hoc networking has been a fast growing research area for the last few years. The need for a network when there is no fixed infrastructure is no more limited to military and emergency applications; ad hoc networks can include private and public applications as well. In ad hoc networks, wireless mobile computing devices can perform critical network topology functions that are normally t...
