1000-T Jitter Test Channel Jon Beckwith

Subclause 40.6.1.1.1 of the IEEE 802.3 Standard defines a test channel to be used in the testing of the jitter on the reference clock of 1000BASE-T devices. The channel consists of two short segments of 120m UTP Category 5 compliant cable, along with one (or two, if necessary) long (the exact length is dependent upon the attenuation of the entire channel) segment of 100m UTP Category 5 compliant cable. The channel is to meet or exceed the insertion loss, crosstalk, and return loss requirements as specified in clause 40.7. The objective of this paper is to outline and describe, in detail, the specifications defined in subclause 40.6.1.1.1 of the IEEE 802.3-2002 standard for the Jitter Test Channel, and observe the results of the testing of a completed test channel. Included are plots, outlining the characteristics of the constructed test channel, along with the limits of each specific test.

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.

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.

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.
