【文章內(nèi)容簡介】
是我將從多方面努力進(jìn)一步提高自身的工作能力,以積極的心態(tài)面對每天的工作任務(wù)。其次,我也將注重鍛煉自己的應(yīng)變能力、協(xié)調(diào)能力、組織能力以及創(chuàng)造能力,不斷在工作中學(xué)習(xí)、進(jìn)取、完善自己,以便更好地完成自己的本職工作。以上是我對兩個月來工作的總結(jié),在今后工作中我將努力奮斗,克服自己的缺點(diǎn),彌補(bǔ)不足,爭取做的更好。我國城域網(wǎng)現(xiàn)狀是sdh/mstp、以太網(wǎng)交換機(jī)、路由器等多個網(wǎng)絡(luò)分別承載不同業(yè)務(wù)、各自維護(hù)的局面,難以滿足多業(yè)務(wù)統(tǒng)一承載和降低運(yùn)營成本的發(fā)展需求。因此,城域網(wǎng)需要采用靈活、高效和低成本的分組傳送平臺來實(shí)現(xiàn)全業(yè)務(wù)統(tǒng)一承載和網(wǎng)絡(luò)融合。分組傳送網(wǎng)(ftn)技術(shù)由此應(yīng)運(yùn)而生。本論文內(nèi)容就是關(guān)于城域分組傳送網(wǎng)的技術(shù)進(jìn)行學(xué)習(xí),演進(jìn)的研究和分析。從業(yè)務(wù)需求ip化入手,首先分析了幾種不同的城域網(wǎng)ip承載技術(shù),比較這幾種技術(shù)的特點(diǎn)及適用范圍,并著重闡述了分組化傳送技術(shù)(ptn)的關(guān)鍵技術(shù)tmpls,指出分組化傳送技術(shù)作為下一代網(wǎng)絡(luò)的核心部件,一方面繼承了mstp網(wǎng)絡(luò)在多業(yè)務(wù)、高可靠、可管理和時鐘等方面的優(yōu)勢,另一方面又具備以太網(wǎng)的低成本和統(tǒng)計復(fù)用的特點(diǎn),在ip業(yè)務(wù)的承載方面具有明顯優(yōu)勢,因此選定分組化傳送技術(shù)作為促進(jìn)網(wǎng)絡(luò)轉(zhuǎn)型,實(shí)現(xiàn)網(wǎng)絡(luò)平滑演進(jìn)的關(guān)鍵技術(shù)。in the metropolitan area networks of our country, sdh/mstp、ethernet switch and routers offer different services and also need different maintance. the development of network needs to offer the services on an unitive platform and decrease the operating costs. therefore, metropolitan area networks will take the flexible, efficient and inexpensive packet transport platform to realize the allip general bearer network. packet transport network technology emerged because of demands. first,it analyzes the existing technologies of metropolitan area transmission network and pares their characteristics and applications environment.then focuses on the technology of ptn(packet transport network)and points out that a
