【摘要】：IP寬帶城域網是電信運營商的承載網,完成城域內互聯網業(yè)務的傳送。由于以電信業(yè)務為基礎的各種使用需求的增多,使得以前的IP城域網,已不能滿足逐漸增長的通信需求。主要表現在對新增加的業(yè)務的持撐,不合理的網絡架構等方面,若想要企業(yè)在激烈的競爭中保持領先的地位,必須根據一定的改進原則和辦法對IP城域網進行改進調整,提升多種業(yè)務和差異化服務的能力。 為構建一個與青海地區(qū)電信業(yè)務需求發(fā)展相適應的寬帶IP城域網,文章對青海寬帶IP城域網的優(yōu)化設計與實現方案進行了研究。 本文基于對目前青海省電信寬帶業(yè)務、網絡現狀分析之后,針對其寬帶網IP城域網進行改造的可行性與必要性。本文簡要概述了寬帶IP城域網優(yōu)化改進所涉及的相關技術理論和相關研究,同時,基于相關理論,探討分析青海寬帶IP城域網的現狀,最后針對存在問題,提出科學、合理、可行的寬帶IP城域網優(yōu)化方案。首先對三層網絡進行結構優(yōu)化改造,主要是改造寬帶接入層和核心層以及匯聚層,構建網絡拓撲結構以適應之；接著規(guī)劃相應路由協議,挑選出的路由協議是高效成熟的,能使網絡壓力獲得減輕,網絡可靠性也得以提升；其次是進行虛擬局域網VLAN標識號的規(guī)劃,以實現新業(yè)務的快速推進擴展部署能力；再對城域網的QoS服務質量及安全問題進行規(guī)劃設計,以增加網絡的健壯性和安全性。最終制定了青海電信寬帶IP城域網詳盡、可操作的優(yōu)化實現方案。通過具體的優(yōu)化方案實施,以實現具有高業(yè)務承載能力的青海電信精品網絡。
[Abstract]:IP broadband metropolitan area network (man) is the carrier network of telecom operators, which completes the transmission of Internet services within metropolitan area. Due to the increase of various usage requirements based on telecommunication services, the previous IP man can no longer meet the increasing communication demand. The main performance of the new business support, unreasonable network structure and other aspects, if enterprises want to maintain a leading position in the fierce competition, must be based on certain improvement principles and methods to improve the IP man, Enhance the ability of multiple services and differentiated services. In order to construct a broadband IP man adapted to the development of telecom services in Qinghai, this paper studies the optimization design and implementation scheme of Qinghai broadband IP man. Based on the analysis of the present situation of telecom broadband service and network in Qinghai Province, this paper analyzes the feasibility and necessity of reforming IP metropolitan area network in its broadband network. This paper briefly summarizes the related technical theory and related research involved in the optimization and improvement of broadband IP metropolitan area network. At the same time, based on the relevant theory, it discusses and analyzes the present situation of Qinghai broadband IP metropolitan area network, finally, aiming at the existing problems, it puts forward scientific and reasonable, scientific and reasonable. Feasible broadband IP man optimization scheme. Firstly, the structure of the three-layer network is optimized, mainly the broadband access layer, the core layer and the convergence layer are reconstructed, and the network topology is constructed to adapt to it; then, the corresponding routing protocols are planned, and the routing protocols selected are highly efficient and mature. It can lighten the network pressure and enhance the network reliability. Secondly, it can plan the VLAN identification number of the virtual local area network, so as to realize the rapid expansion and deployment ability of the new service. In order to increase the robustness and security of man, the QoS quality of service and security of man are planned and designed. Finally, a detailed and operable optimization scheme of Qinghai Telecom broadband IP metropolitan area network is established. Through the implementation of specific optimization scheme, Qinghai Telecom excellent network with high service carrying capacity is realized.
