NIST TN1337: Characterization of Clocks and Oscillators D.B. Sullivan, D.W. Allan, DA. Howe, F.L. Walls

This is a collection of published papers assembled as a reference for those involved in characterizing and specifying high-performance clocks and oscillators. It is an interim replacement for NBS Monograph 140, Time and Frequency: Theory and Fundamentals, an older volume of papers edited by Byron E. Blair. This current volume includes tutorial papers, papers on standards and definitions, and a collection of papers detailing specific measurement and analysis techniques. The discussion in the introduction to the volume provides a guide to the content of the papers, and tables and graphs provide further help in organizing methods described in the papers

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.

White Papers February 6, 2006
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 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.

Moonv6 PhaseII Whitepaper UNH-IOL

Phase II of the Moonv6 project established the largest native IPv6 network in the world. The second phase of the project was able to demonstrate high speed links, advanced routing functionality, firewalls, QoS, and other key features. More than two dozen organizations participated in Phase II, and testing was facilitated by engineers from nine separate sites.

White Papers July 5, 2004
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.

White Papers November 3, 2003
Moonv6 June 2007 Whitepaper UNH-IOL

The testing documented in this paper took place in June 2007 and focused on end-to-end basic office application demonstrations including printing scenarios, NFS (Network File Share), web design tools, collaboration tools, and SHIM6(Site Multihoming By IPv6) in a multivendor environment.

Moonv6 2006 Whitepaper UNH-IOL

During the July 2006 test set, protocol-specific test plans were executed at both the UNH-IOL and the JITC Ft. Huachuca sites. IPv6 Information Assurance vulnerabilities assessment identified vulnerabilities in individual devices and within networks that are representative of operational DoD systems. Testing involved network applications including Network Time Protocol (NTP), DoD IPv6 Information Assurance, IPSec, DNS, DHCP, Firewalls and Applications, Transition Mechanisms and Dual-Stack Routing.

Moonv6 2005 Whitepaper UNH-IOL

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.

White Papers March 20, 2006
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).

Making Auto-Negotiation & Link Training Reliable and Why It Matters Kae Dube, UNH-IOL & Joshua Harsch & Craig Foster, Teledyne LeCroy Learn about Auto-Negotiation (ANEG) and Link Training (LT) by looking at common issues folks may run into during testing. Successful ANEG and LT have shown to reduce overall installation time while minimizing the risk of ongoing mistakes. This video will cover an introduction to ANEG: Why it’s used and how it's implemented, how ANEG reduces time for manual configuration and minimizes 'mistakes' and much more! Tutorials August 31, 2022
