Very High Speed Backbone Network Services Provider for NSFNET and the NREN (SM) Program

9321047利巴伯MCI将提供NSFnet甚高速骨干网络服务(VBNS)，如项目征集NSF93-52中所定义。这项服务将在MCI基于SONET技术的生产电信基础设施中运营。五个超级计算机中心(SCC)和NSF指定的网络接入点(NAP)将与vBN互联。对vBNS的访问将以具有异步传输模式(ATM)访问的SONET OC-3数据速率(155 Mbps)开始，并将在5年授权期内增加到每秒千兆比特。OC-12接入(655 Mbps)预计到1996年可用。到1998年，具有OC-48(2.00 GB/秒)接入SCC的OC-192(9.6吉比特/秒)SONET主干有望实现。MCI将提供一个测试网，以支持新电信技术的试验。

9321047 Liebhaber MCI will provide the NSFNET very high speed Backbone Network Service (vBNS) as defined in project solicitation NSF 93-52. This service will be operated from MCI's production telecommunications infrastructure based on SONET technology. Five supercomputer center (SCCs) and the NSF designated Network Access Points (NAPs) will be interconnected to the vBNS. Access to the vBNS will commence at SONET OC-3 data rates (155 Mbps) with Asynchronous Transfer Mode (ATM) access and will increase to gigabit per second rates over the 5 year award period. OC-12 access (655 Mbps) is estimated to be available by 1996. By 1998 an OC-192 (9.6 Gbits/sec) SONET backbone with OC-48 (2.$ GBits/sec) access to SCCs is anticipated. MCI will make a Testnet available in support of experimentation with new telecommunications technologies.
