信元抖動 的英文怎麼說
中文拼音 [xìnyuándǒudòng]
信元抖動
英文
cell jitter-
We focus on study and design of medium access control ( mac ) protocol used in apon. the mac protocol must have excellent performance to certify as small transfer delay ( td ) and cell delay variation ( cdv ) as possible to meet all kinds of services besides no collision between cells
我們在本論文研究的重點就是設計一個媒質接入控制協議，使得用戶上行信元有序到達olt而不發生碰撞，同時保證各業務所要求的傳輸時延（ td ）和信元時延抖動（ cdv ） 。By theory analysis and computer simulation, dual control write sequence read medium access control protocol ( d - mac ) we bring forward works better than typical global fifo mac protocol. in order to let residential and small business customers enjoy all kinds of services that backbone network provides economically as early as possible, we design a switch hub
經過理論分析和計算機模擬，可以證明我們提出的雙控制寫入順序讀出媒質接入控制協議（ d - mac ）是一個非常有效的，比典型的globalfifomac協議具有更小的傳輸時延和信元時延抖動。As a part of whole atm network, apon should be in concert with the traffic control policies of atm. for this, the mac protocol should minimize the cell jitter over passed stream with effort in the access phase
作為整個atm網路的一部分， apon必須能與atm網路的流量監控措施保持協調一致，其要求是盡量降低信元流的時延抖動。Secondly, uses uml to build a general and useful model for h. 323 stack, and divides the stack into several modules under the principle of ooa, and realizes the stack programming with oop language on the base of a cross - platform classes - pwlib. subsequently, fluctuation in video transmission is deeply analyzed and a useful solution is presented. finally, a simulation terminal software is developed on the base of h. 323 stack, then the stack is tested with unit testing and systemic testing
本文首先對h . 323標準進行了概括性的介紹，包括它所定義的實體、協議棧、通信過程；用uml和面向對象的思想對h . 323協議棧進行建模；實現了h . 323協議棧的模塊化劃分，並用跨平臺的pwlib類庫實現了h . 323協議棧；隨后對會議電視中視頻通信數據網路抖動的消除方法做了深入的研究，並在此基礎上給出了一種有效的解決方案；最後，基於h . 323協議棧，開發了h . 323模擬終端，並用單元測試、系統測試的方法對協議棧進行了嚴格的測試。分享友人
