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(xié)議棧、通信過程;用uml和面向?qū)ο蟮乃枷雽 . 323協(xié)議棧進行建模;實現(xiàn)了h . 323協(xié)議棧的模塊化劃分,并用跨平臺的pwlib類庫實現(xiàn)了h . 323協(xié)議棧;隨后對會議電視中視頻通信數(shù)據(jù)網(wǎng)絡(luò)抖動的消除方法做了深入的研究,并在此基礎(chǔ)上給出了一種有效的解決方案;最后,基于h . 323協(xié)議棧,開發(fā)了h . 323模擬終端,并用單元測試、系統(tǒng)測試的方法對協(xié)議棧進行了嚴格的測試。
