ATM Protocol Reference Model
A multidimensional protocol model consisting of 4 layers and 3 planes and serving as a point of reference for understanding, developing and implementing ATM technology. Each layer addresses a discrete set of related functions, with all layers closely interrelated. The layers include the Physical Layer, ATM Layer, ATM Adaptation Layer, and Higher Layers related to the specifics of the native user data protocol. The planes include the Control Plane, User Plane and Management Plane.
ATM 协议参考模型
一种多维协议模型，包括4个分层和3个平面，用作理解、开发和实现ATM技术的参考点。每一个分层执行一组离散的相关功能，所有分层都紧密的相互关联。这些分层包括物理层、ATM层、ATM适配层以及与原来的用户数据协议细节相关的高层。3个平面有控制平面、用户平面以及管理平面。
ATM Switch
A networking device that forwards 53-byte ATM-standard cells between different devices. These switches can be designed for both LAN and WAN environments. An ATM switch acts as both a traffic aggregator, such as when terminating unchannelized DS-3 trunks from DSLAMs, and as a multiservice switch that is capable of forwarding traffic in different ways, depending on what has to be done with it. For example, an ATM switch forwards customer IP traffic directly to an IP network by shunting it to a router or subscriber management system, frame-relay traffic to a frame switch, voice-over-ATM traffic to a voice/data gateway, or long-distance traffic to other central offices via a SONET inter-office ring.
ATM交换机
一种网络设备，在两个不同设备之间传输53字节ATM标准信元。这些交换机可以设计用于LAN（局域网）和WAN（广域网）。 ATM交换机可以用作信息传输集合器，例如可以终止来自DSLAM的未作信道使用的DS-3中继线；也可以用作多业务交换机，能够根据预先设置以不同方式传输信息。例如，ATM交换机通过将信息分流到路由器或用户管理系统、将帧中继信息分流到帧交换机、将ATM话音信息分流到话音/数据网关或者将长途信息通过SONET局间环路分流到其他市话局来将客户IP信息流直接传输到IP网络。
ATM Token Ring LAN Service Unit
The ATM TLSU provides a powerful tool for offering internetworking services over ATM networks. Emulated token rings consist of up to 64 TLSU token ring ports located anywhere in the ATM network, interconnected with PVCs. These emulated token ring networks can be completely isolated from one another to ensure security and fairness among the attached LANs. The TLSUs are designed for flexible deployment, either local to an ATM switch or at a remote site. See ATM Ethernet LAN Service Unit.
ATM令牌环服务单元
ATM TLSU提供了功能强大的工具，在ATM网络中提供网间服务。仿真令牌环最多可以由多达64个TLSU令牌环端口组成，放置在ATM网络任意位置，提供PVC间的互连。这些仿真令牌环网络可以完全独立于其他仿真令牌环，以确保连接到局域网的各仿真令牌环的安全和公平。TLSU的设计使其能够灵活应用，无论是本地环路连接ATM交换机还是远端站连接ATM交换机。参见ATM Ethernet LAN Service Unit。
ATM Traffic Descriptor
A generic list of traffic parameters that can be used to capture the intrinsic traffic characteristics of a requested ATM connection.
ATM流量描述符
一种普通的流量参数列表，可以用于获取所需的ATM连接内在流量特性。
ATM User-User Connection
An association established by the ATM Layer to support communication between two or more ATM service users (i.e., between two or more next higher entities or between two or more ATM-entities). The communications over an ATM Layer connection may be either bidirectional or unidirectional. The same Virtual Channel Identifier (VCI) is issued for both directions of a connection at an interface.
ATM用户和用户连接
ATM层建立的一种联系，支持两个或两个以上ATM服务用户（即两个或两个以上高级实体之间或两个或两个以上ATM实体之间）之间的通信。ATM层连接上的通信可以是双向的或者的单向的。在一个接口中，相同的虚路径标识符(VCI)可以沿链路双向传输。
ATMARP
ATM Address Resolution Protocol. The means of mapping IETF classical IP addresses to ATM hardware addresses. The process works in much the same way as conventional ARP, which maps network-layer addresses to the MAC (Media Access Control) layer in a LAN.
