Research on Advanced Communication Systems

这是一个关于适合实施下一代大型公共网络的先进通信系统的研究项目。首席研究人员构思了一种名为广播分组交换的新技术，该技术应该支持包括语音、数据、广播视频(TV)和语音/视频电话会议在内的广泛应用。今天，电话和电缆网络都面向特定的应用，各自使用的通信技术与其主要应用很匹配，但不太适合大多数其他应用。虽然电话网络可以用于数据通信，但这通常需要使用提供慢速、噪声通道的调制解调器。因此，利用现有和目前规划的技术，可能需要三个独立的专用应用程序网络来满足公众快速增长的通信需求。这项调查的成功结果将通过开发能够同时支持各种应用的综合网络来满足长期的通信需求。

This is a research project on advanced communications systems suitable for implementing the next generation of large public networks. The principal investigator has conceptualized a new technology called broadcast packet switching that should support a wide range of applications including voice, data, broadcast video (TV) and voice/video teleconferencing. Today, telephone and cable networks are oriented towards a specific application and each uses a communications technology well-matched to its principal application but poorly suited to most others. Although telephone networks can be used for data communications this usually requires the use of modems which provide slow, noisy channels. Thus, with existing and presently planned technologies, three separate, dedicated, applications networks may be required to meet the rapidly growing communications needs of the general public. Successful results from this investigation will satisfy long term communications needs through development of an integrated network capable of supporting a wide variety of applications simultaneously.
