Moonv6 PhaseI Whitepaper UNH-IOL

Phase I of Moonv6 demonstrated that current IPv6 networking technology is stable, resilient and ready for integration with today\'s Internet. The event was attended by more than thirty different organizations and confirmed several stable and interoperable implementations of IPv6, and proved that IPv6 is ready to be deployed on a global scale. Specific aspects of IPv6 included common network applications, base specifications, transition mechanisms, routing protocols, security and mobility.

MPLS World Congress 2004 MFA and EANTC

This interoperability evaluation focused on the transport of differentiated services on a multi-vendor MPLS backbone supporting MPLS traffic engineering. The MPLS World Congress 2004 demonstrated differentiated services over MPLS and MPLS traffic engineering. Multi-vendor MPLS/BGP VPN\'s and Layer 2 Ethernet VPN\'s (Martini and VPLS) were configured to prove that services were traffic engineering-enabled and could process differentiated services.

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.

MPLS World Congress 2006 Jambi Ganbar, Jonathan Morin, Cartsen Rossenhoevel, and Gabriele Schrenk

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.

OSRM January 2004 Chris Volpe, Ichiro Inoue, Kaori Shimizu, Yumiko Kawashima, and Tom Dimicelli

The first OSRM event, held at the University of New Hampshire InterOperability Laboratory (UNH-IOL), provided an aggressive carrier-class environment for GMPLS testing including several GMPLS interworking scenarios that had not been achieved in previous multi-vendor test settings. The testing, conducted by the UNH-IOL OSRM test group, involved a variety of test cases that focused on stability testing, control channel fault handling and data channel failure recovery.

OSRM Test Event 2004 Henry He, Chris Volpe, Takumi Ohba, Kaori Shimizu, Yumiko Kawashima, and Tom DiMicelli

The second UNH-IOL OSRM test event included seven different companies and was designed in collaboration with Nippon Telegraph and Telephone Corp. (NTT) and the participants to validate and prove GMPLS functionality in a multi-vendor network. This collaboration generated an exceptionally realistic and demanding test suite in line with service providers\' operational demands, rather than simple conformance or interoperability scenarios.

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.

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.
