Abstract

The volume of data transmission required by current software applications utilizing graphical user interfaces, visualization and imaging techniques, and large databases, is taxing, and in some cases, overloading the capabilities of classic local area networks such as Ethernets and token rings. Multimedia applications that will be appearing and maturing in the near future will further exceed the capabilities of these networks. These effects have engendered the development of a number of new local area network protocols that attempt to bring higher throughput capacities to the network user. The behavior and operation of one of these new networks, 100VG-AnyLAN, the 100 megabit per second demand priority protocol proposed by IEEE 802.12, is the subject of this paper. We begin with a short discussion of common existing networks to place 400VG-AnyLAN in context with established networking technologies. The operation of single hub and cascaded hub 100VG-AnyLAN systems is discussed, along with the features of physical layer signalling on voice grade twisted pair cabling. Finally, a summary of the types of real-time and multimedia guarantees that can be provided by the 100VG-AnyLAN system is presented.<>

100VG-AnyLAN:网络运行和实时能力

利用图形用户界面、可视化和成像技术以及大型数据库的当前软件应用程序所需的数据传输量非常大，并且在某些情况下，使传统局域网(如以太网和令牌环)的功能过载。在不久的将来，即将出现和成熟的多媒体应用程序将进一步超越这些网络的能力。这些影响导致了许多新的局域网协议的发展，这些协议试图为网络用户带来更高的吞吐能力。本文研究的是其中一种新型网络——100VG-AnyLAN的行为和运行，该网络是IEEE 802.12提出的每秒100兆比特的需求优先协议。我们首先简要讨论常见的现有网络，以便将400VG-AnyLAN置于已建立的网络技术的背景下。讨论了单集线器和级联集线器100VG-AnyLAN系统的工作原理，以及语音级双绞线布线中物理层信令的特点。最后，总结了100VG-AnyLAN系统所能提供的实时性和多媒体保障的类型。
