OSRM Test Event 2005 Henry He, Takumi Ohba, Kaori Shimizu, Chris Volpe, John Allen, Ankur Chadda, and Scott Larsonk

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.

MPLS World Congress 2005 Carsten Rossenhoevel, Michael Pergament, and Jonathan Morin

The second MPLS World Congress interoperability event included 10 different companies and was hosted by the MPLS Forum and Frame Relay Alliance at the EANTC labs in Berlin, Germany. The demonstration, held at the MPLS World Congress in Paris, proved that MPLS Layer 2 Ethernet-based VPNs are ready for large scale deployment. Also demonstrated were minimal MPLS ping and traceroute implementations.

Moonv6 2004 Whitepaper UNH-IOL

The November test set explored several new areas, including VoIP via Session Initiation Protocol (SIP), wireless LANS and streaming video via Multicast. Particular areas of testing included IPsec, DNS, DHCP, iSCSI, routing, tunneling and QoS. The November testing was attended by 16 different vendors, and results proved that IPv6 is stable and capable of running key data communications applications (voice-based services and multicast).

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.
