High - speed, muti - services and economy have become the major issues of the future ip backbone technology as far as thes poiflt is concerned, thes paper explores layer 3 switdrig technology which separates control component and forward compontal in the traditional roulers. two forwarding al gori thms - - - - d ata - driven mo d el and top olo gy driven model are also compared, a next generation ip backbone echno l o gy - - - - multiproto co l label switching is developed, with its operation and its deployinent in traffic engineering, c1ass - ofservce and virtual private network
本文從未來ip骨幹網技術所要求的高速化、多業務支持、經濟性出
發,介紹了在傳統路由器基礎上將控制部件和
轉發部件分離的第三層交換技術,比較了數據驅動模型和控制驅動(拓撲驅動)模型兩種
轉發演算法,並由此引出下一代ip骨幹網路技術? ?多協議標記交換,闡述了其工作原理以及在流量工程、服務等級區分和虛擬專用網中的應用。

After these things have been done, we research and design the modular software router ? msr, basing on the requirement of the forwarding node under the openrouter architecture
在此基礎上,根據openrouter體系結構對
轉發結點的要求,研究和設計模塊化軟體路由器msr 。
The outmost layer ( c - layer - communication layer ) deals with i / o issues between the ums and outside communication world ; the inner most layer ( k - layer, kernel layer ) involves internal management and message storage ; while the middle layer ( a - layer - auxiliary layer ) plays the go - between function between layers c and k. as the core component in layer k, the ums mail server is responsible for the storage, transmission and management of the system driven by the layer - k state machine
文中設計的zhx - ums是一個三層系統,最外層( c層?通信層)處理ums和外部通信世界的i o問題;最內層( k層?核心層)負責內部的消息管理和消息存儲;中間層( a層?輔助層)處理c層與k層之間的通信及消息格式
轉換。 ums郵件服務器是系統三層體系結構中k層的核心模塊,在k層協議機驅動下完成存儲、
轉發及管理等任務。
It is composed of three mian protocols : call synchronization protocol, control frame transmission protocol based on arq mechanism and data transmisstion protocol based on slot precontract mechanism. one scan channel table is shared in the hfmanet. the nodes in the same dwell group work in the same scan channel, and the nodes in the different dwell group work in the different scan channel
該協議的網路拓撲結構採用分散式分群結構,協議不同於傳統的短波點到點及需要中心節點
轉發的組網方式,而是初步實現了短波電臺之間多跳組網功能,其協議內容主要包括同步呼叫協議、基於arq的控制幀傳輸協議和基於虛電路及時隙預約方式的數據幀傳輸協議。
To compensate centimeter wave ' s shorting comings such as broad beam and short effective range, a transponder is added in the back of target automotive. this secondary radar measures range in the way of transponding
為了彌補厘米波波束大、作用距離不如毫米波的缺點,系統在目標車輛的尾部增加了一級
轉發器,以雙機應答的方式測量車距。
The communication model is a twp - tier architecture, the main function of superstratum ( name server ) is tracing the domain which target agent belong to presently. the main function of substrate ( domain - inside tracing machine ) is the message transfer and denominating the new created agent
本文所提的通信模型分為了兩層結構,上層的名字服務器主要提供按名字追蹤目標agent所屬域的功能,下層的域內追蹤器完成消息
轉發及為新生agent命名的功能。
