in mathematics, medicine, and language Additionally, the MECCANO broadbandnetwork platform interoperates with SMDS (Switched Multimegabit Data Service),DBS (Direct Broadcast Satellite), and ISDN (Integrated Services Digital Network)technologies However, the quality of audio and sound, the speed of transmission,and the degree of interactivity with SMDS, DBS, and ISDN is not equivalent totransmission speeds and services provisioned by ATM technology

11.14.3.1 MECANNO MBS (Managed Bandwidth Service)

The MECANNO (Multimedia Education and Conferencing Collaboration over ATMNetworks) initiative established procedures in alpha and beta tests for setting upMBS accounts, defined operations performed by the ATM NOC (Network Opera-tions Center) in support of MBS functions, and identified and resolved problemsassociated with internetworking NREN implementations Alpha and beta trials viathe MECANNO platform also confirmed MBS reliability MBS alpha trials at theUniversity College London, Essen University, and the University of Stuttgart verifiedMBS effectiveness in provisioning committed bandwidth for VPN implementationsand MBS support of interactive telecollaborative research In 1999, TEN-155 (TransEuropean Network-155.52 Mbps) conducted beta tests that verified MBS (ManagedBandwidth Service) capabilities in supporting virtual classroom sessions betweenschools situated in Ottawa and Edmonton in Canada; Dublin, Ireland; Basel, Swit-zerland; and Berlin, Germany

11.15 TEN-155 (TRANS-EUROPEAN NETWORK-155.52 MBPS) 11.15.1 TEN-155 F EATURES AND F UNCTIONS

A successor network to TEN-34, TEN-155 provisioned an international ture for connecting next-generation networking initiatives such as APAN, I2, and

infrastruc-National Research and Education Networks (NRENs) in countries that included theCzech Republic, Iceland, Hungary, Norway, Switzerland, and Slovenia To facilitatedevelopment of a pan-European network infrastructure, TEN-155 supported IP mul-ticasts, high-speed multimedia transmissions, advanced telecollaborative research,and implementation of new networking technologies, and VPN (Virtual PrivateNetwork) deployments that used MBS (Managed Bandwidth Service) TEN-155also operated connection points in Amsterdam and Frankfurt for peer-level trafficexchange and employed a combination of IP, ATM, and SDH (Synchronous DigitalHierarchy) technologies to support interoperable networking applications andprojects DANTÉ (Delivery of Advanced Network Technology to Europe, Ltd.)managed TEN-155 operations.

The DANTÉ Network Engineering and Planning Group supported migrationfrom TEN-34 (Trans-European Network-34.368 Mbps) to TEN-155 and initiallyconducted pilot tests to verify capabilities of high-speed services and applicationsslated for TEN-155 implementation In addition to DANTÉ, the Trans-EuropeanResearch and Education Networking Association (TERENA), and the joint TERENAand DANTÉ Task Force (TF-TANT) conducted tele-education and tele-researchapplications in the context of the Quantum Test Program (QTP) In 1999, DANTÉestablished a 44.736 Mbps (T-3) connection between TEN-155 NRENs and theAbilene network via STAR TAP and the SBC/AADS NAP (Network Access Point)

in Chicago DANTÉ and DFN (NREN of Germany) also formed a Consortium calledCAPE (Connecting Asia-Pacific and Europe) to establish interconnectivity betweenTEN-155 NRENs and major international networks such as APAN At the outset,TEN-155 implemented an IP network overlay on top of the ATM platform andsupported best-effort packet delivery service However, multimedia services depend

on QoS (Quality of Service) guarantees Because these guarantees were not provided

in a best-effort IP network, TEN-155 subsequently deployed MECCANO-supportedMBS (Managed Bandwidth Service)

DANTÉ enhanced the capabilities of the TEN-155 infrastructure by upgradingthe central SDH ring linking NRENs in France, Germany, the United Kingdom, andthe Netherlands to support increased rates at 622.08 Mbps (OC-12) EuroCERT(European Union Computer Emergency Response Team) provisioned security ser-vices for TEN-155 members NREN participants in EuroCERT include ACONET(NREN of Austria), ARNES (NREN of Slovenia), DFN (NREN of Germany),Renater2 (NREN of France, Phase 2), SURFnet5 (NREN of the Netherlands, Phase5), SuperJANET4 (Super Joint Academic Network, Phase 4), UNINETT (NREN ofNorway), and RedIRIS (NREN of Spain)

It is interesting to note that TEN-155 NRENs transported commercial traffic andtraffic generated by research centers and educational institutions In contrast to TEN-

155, the Abilene and the vBNS+ Internet2 (I2) backbone networks only carry performance research and education transmissions generated by I2 entities Thecommodity or public Internet supports delivery of commercial traffic and trafficgenerated by educational institutions and research centers that are not I2 affiliates.(See Figure 11.4.)
