|Overview of UNH EXS for Programmers||Robert Russell, Patrick MacArthur||
The Extended Sockets API (ES-API) is a specification published by the Open Group that defines extensions to the traditional socket API in order to provide asynchronous I/O and also memory registration for Remote Direct Memory Access (RDMA). These two major new features enable programmers to take advantage of today's multi-core processors and RDMA network hardware, such as InfiniBand, iWARP and RoCE interfaces, in a convenient yet efficient manner.

|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.

|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.
