本文提出在令牌总线局部网中实现综合业务的基本建设思想。目前局部网内采用的包交换技术是适合于数据业务特征的。为了纳入话音业务,就需要保证话音包传输的实时性。本文在阐述专门用于数据通信的局部网协议标准802.4的基础上,提出在协议中增加定时管理、设置令牌循环周期、给话音站实时提供令牌等办法,以便能用统一的包交换方式实现话音与数据业务的综合,达到综合业务局部网的首要目标。
This paper proposes a basic idea of implementing integrated services in Token Bus local network. Packet switching technology currently used in the local area network is suitable for data traffic characteristics. In order to include voice services, you need to ensure the real-time voice packet transmission. Based on the 802.4 local network protocol standard devoted to data communication, this paper proposes to increase the timing management in the protocol, set the token cycle period, and provide token to the voice station in real time so that the unified packet exchange Achieve the synthesis of voice and data services, to achieve the primary goal of integrated services network.
