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 協(xié)議參考模型
一種多維協(xié)議模型，包括4個分層和3個平面，用作理解、開發(fā)和實現(xiàn)ATM技術(shù)的參考點。每一個分層執(zhí)行一組離散的相關(guān)功能，所有分層都緊密的相互關(guān)聯(lián)。這些分層包括物理層、ATM層、ATM適配層以及與原來的用戶數(shù)據(jù)協(xié)議細(xì)節(jié)相關(guān)的高層。3個平面有控制平面、用戶平面以及管理平面。
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交換機(jī)
一種網(wǎng)絡(luò)設(shè)備，在兩個不同設(shè)備之間傳輸53字節(jié)ATM標(biāo)準(zhǔn)信元。這些交換機(jī)可以設(shè)計用于LAN（局域網(wǎng)）和WAN（廣域網(wǎng)）。 ATM交換機(jī)可以用作信息傳輸集合器，例如可以終止來自DSLAM的未作信道使用的DS-3中繼線；也可以用作多業(yè)務(wù)交換機(jī)，能夠根據(jù)預(yù)先設(shè)置以不同方式傳輸信息。例如，ATM交換機(jī)通過將信息分流到路由器或用戶管理系統(tǒng)、將幀中繼信息分流到幀交換機(jī)、將ATM話音信息分流到話音/數(shù)據(jù)網(wǎng)關(guān)或者將長途信息通過SONET局間環(huán)路分流到其他市話局來將客戶IP信息流直接傳輸?shù)絀P網(wǎng)絡(luò)。
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令牌環(huán)服務(wù)單元
ATM TLSU提供了功能強(qiáng)大的工具，在ATM網(wǎng)絡(luò)中提供網(wǎng)間服務(wù)。仿真令牌環(huán)最多可以由多達(dá)64個TLSU令牌環(huán)端口組成，放置在ATM網(wǎng)絡(luò)任意位置，提供PVC間的互連。這些仿真令牌環(huán)網(wǎng)絡(luò)可以完全獨立于其他仿真令牌環(huán)，以確保連接到局域網(wǎng)的各仿真令牌環(huán)的安全和公平。TLSU的設(shè)計使其能夠靈活應(yīng)用，無論是本地環(huán)路連接ATM交換機(jī)還是遠(yuǎn)端站連接ATM交換機(jī)。參見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
一種普通的流量參數(shù)列表，可以用于獲取所需的ATM連接內(nèi)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用戶和用戶連接
ATM層建立的一種聯(lián)系，支持兩個或兩個以上ATM服務(wù)用戶（即兩個或兩個以上高級實體之間或兩個或兩個以上ATM實體之間）之間的通信。ATM層連接上的通信可以是雙向的或者的單向的。在一個接口中，相同的虛路徑標(biāo)識符(VCI)可以沿鏈路雙向傳輸。
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.
