|A Comparison of Efficiency, Throughput, and Energy Requirements of Wireless||Anthony Murabito||
As energy sources are dwindling, power consumption is a major obstacle facing virtually every industry. Alongside Internet access, wireless computer networks, more commonly known as Wi-Fi networks, have become widely adopted. These wireless networks have found their way into our homes and have also spread to the enterprise market. The goal of this research is to study the power consumption of wireless Access Points, and determine possible means to reduce the energy requirement of the Access Point.

|Performance Evaluation of TCP over IEEE 802.11 WLANs||Sachin Goel||
Transmission Control Protocol (TCP) is a communication protocol that is used to provide reliable data delivery between hosts. As TCP is the most highly used transport-layer protocol, many have worked on addressing the issue of performance. Performance issues have been studied in various environments, especially when using 802.11 Wireless Local Area Networks (WLANs). Wireless networks are prone to a higher number of packets loss and corruption. 802.11 WLANs have an equivalently fast acknowledgement mechanism as TCP to ensure reliability of traffic over it. This duplication of functionality between TCP and 802.11 WLAN creates unexpected behaviors that can result in high costs in terms of overall performance. A significant amount of analytical and simulation work has been done in the past to study the behaviour of TCP over 802.11 WLANs. The main contribution of this work is the analysis of TCP interaction in an 802.11 WLAN topology by using real commercial-grade equipments. A testing methodology is designed to do the quantitative performance evaluation in a network topology consisted of wired as well as a wireless connection. The methodology contains test scenarios with different configurable settings on an Access Point (AP) and various controlled impairments in the network topology such as latency, packet drop, noise interference, etc. The performance of TCP is measured in terms of the throughput. This work provides a comprehensive set of experiments to study the behaviour of TCP over 802.11 WLANs. The results can provide insight into the performance cost associated with TCP traffic on 802.11 WLANs under different network environments and configurations on the AP. The results of this work thus have a value to equipment manufacturers and network operators.

This round of testing aimed to improve the conformance, stability, and internetworking capability of multiple commercial implementations of IPv6. The event was attended by 11 organizations. Where previous rounds of testing were focused on testing core network areas, objectives for this round were to demonstrate advances in IPv6 applications, including DHCP, voice services, mobility, DHCP, DNS/DHCP resolution, application layer (VoIP), and security (IPsec). A successful VoIP call was made over IPv6 from New Hampshire to South Korea using commercial software.

The MPLS World Congress 2006 interoperability event included 15 different companies and was hosted by the EANTC and UNH-IOL and was endorsed by the MPLS Forum and Frame Relay Alliance, held in Berlin, Germany. This event focused the convergence of both old and new MPLS services such as VPLS, BGP-VPNs, Layer 2 VPNs while still being guaranteed by Fast Reroute and MPLS Diff Serve. The event was especially successful in focusing on converged services as it included all classes of MPLS devices.

|WPA-PSK: Step-by-Step||Jeremy deVries||
In today's age of ubiquitous SOHO networks and ever more Wi-Fi in laptops, security is a paramount concern. Unsecured or improperly set up wireless networks can leave you vulnerable to intrusion, viruses, hijacking of bandwidth, and more problems than one can list, which is why properly setting up your secured network using an authentication mechanism such as WPA-PSK is a crucial step in creating a wireless network. This article provides an overview of the Wi-Fi Protected Access Pre-Shared Key (WPA-PSK) security mechanism, and a step-by-step guide to securing your wireless network.

The third UNH-IOL OSRM test event was designed with a new focus on the failure recovery mechanisms of a GMPLS network. The event provided a vendor-neutral setting that gave participants an opportunity to assess interoperability and valuable feedback to assist them in refining their implementations. Testing included interconnected products demonstrating the functionality of various aspects of explicit route and label control to set up GMPLS traffic engineered most suitable path, control channel failure recovery, data plane failure recovery by multi-layer traffic engineering, end-to-end protection in signaling, and the ability of GMPLS to manage diverse networks with increased scalability.

|Voice Over IP and Wireless Data Coexistence in a WLAN Switch Deployment||Tom Leary, UNH-IOL; Aruba Networks||
Wireless technology is becoming increasingly integrated into the world's networks. Recent innovations, such as offloading processing to wireless local area network (WLAN) switches at the network's edge, have cleared the way for large-scale enterprise deployments. However, despite improved maintenance and administration tools, switched WLAN networks are vulnerable to issues arising from the heterogeneous network environment, especially the integration of services such as voice over IP (VoIP). An open-industry enterprise services and security test event held from March 21 to March 25, 2005 at the University of New Hampshire InterOperability Laboratory (UNH-IOL) provided a backdrop for testing these solutions.

|Quality of Service Testing Methodology||Ankur Chadda||
Typically, a network service provider offers best-effort service to customers and Quality of Service (QoS) is provided only by network over provisioning. When traffic bursts cause congestion, this default approach does not always provide an acceptable solution. As the trend in networking is convergence of voice, video and data, it is important to differentiate traffic into high and low priority classes through QoS mechanisms. To deliver differentiated QoS, the routers utilize classification and sometimes remarking of the traffic. Based on service agreements with the customer, a certain class of traffic is then given more resources by the router. Evaluation of the results of these methods and approaches on the network performance is very important to device designers, network evaluators, network administrators, network operators and others involved. To study the effects of QoS solutions/techniques on the traffic, methods for testing need to be developed. The objective of this thesis is to propose methods of measuring QoS metrics like throughput, latency, and jitter for different types of traffic through a device. Classification and remarking were observed to put extra load on a device. For some devices, the performance deteriorates when classification and remarking are enabled. Throughput was seen to drop for classification and remarking in some cases. In multiple instances, latency and jitter increased for classification and remarking. There are multiple ways of measuring jitter which were also discussed in the methodology development. It was also observed that some definitions which might seem better from a research perspective are not always available to measure or widely used in the industry. Based on the study it was concluded that service/network providers will have to take care while providing QoS to the customers in order avoid the scenarios discussed here.
