【摘要】：隨著經(jīng)濟(jì)的發(fā)展,人們對帶寬的需求也不斷的增長,ADSL已經(jīng)成為網(wǎng)絡(luò)應(yīng)用的一種瓶頸,而FTTH的到來引領(lǐng)人們進(jìn)入光纖入戶的時代,其在帶寬方面的優(yōu)勢使得它成為未來網(wǎng)絡(luò)接入發(fā)展的理想方向。目前FTTH纖芯路由的設(shè)計缺乏科學(xué)性,讓人們在后期的維護(hù)中產(chǎn)生了很大的障礙,纖芯路由的使用與維護(hù)極其耗時耗人工,而且判斷準(zhǔn)確率較低,經(jīng)常引發(fā)重復(fù)投資。本文在分析FTTH纖芯路由特點的基礎(chǔ)上,充分考慮光纜纖芯利用率及權(quán)重,結(jié)合了蟻群算法的特點設(shè)計了一種基于旋轉(zhuǎn)模型的改進(jìn)蟻群算法。為其在FTTH纖芯路由設(shè)計、纖芯路由查找、纖芯路由擴(kuò)容、纖芯路由搶修等方面提供了一種新的理論思路。論文在研究FTTH建設(shè)模式及結(jié)構(gòu)的基礎(chǔ)上以某小區(qū)案例探討了FTTH纖芯路由策略。主要任務(wù)是考慮權(quán)值情況下基于旋轉(zhuǎn)模型的蟻群算法對FTTH纖芯路由進(jìn)行脆測及路由探索仿真比較,結(jié)果表明考慮權(quán)值情況改進(jìn)的纖芯路由蟻群算法在資源利用、維護(hù)效率等方面提供更為智能化的優(yōu)勢,可以在一定程度上對FTTH纖芯路由進(jìn)行預(yù)分配,減少了FTTH用戶在路由方面探索的時間,也為后期FTTH用戶的維護(hù)與纖芯路由擴(kuò)容等提供了理論參考。本文的主要工作包括：1.引入了纖芯旋轉(zhuǎn)模型的方法。根據(jù)FTTH纖芯路由概念的特點,設(shè)計了纖芯路由旋轉(zhuǎn)模型,使其更好的進(jìn)行纖芯路由的管理和控制。2.蟻群算法與權(quán)重的結(jié)合分析。根據(jù)纖芯特點與光纖衰耗的關(guān)系,將權(quán)重概念獨立劃分,與蟻群算法的集合使其更加突出在蟻群路徑上的復(fù)雜性與纖芯中權(quán)重概念的重要性。3.基于旋轉(zhuǎn)模型的蟻群算法的纖芯路由分析與對比。與常見的幾種路由算法在FTTH纖芯路由方向的對比,可以看出基于旋轉(zhuǎn)模型的蟻群算法的優(yōu)勢。4.用實例FTTH討論纖芯路由故障判斷的仿真與分析。根據(jù)某電信分公司某小區(qū)FTTH的現(xiàn)狀,結(jié)合基于旋轉(zhuǎn)模型的蟻群算法進(jìn)行纖芯路由分析和對比。
[Abstract]:With the development of economy, the demand for bandwidth has been increasing. ADSL has become a bottleneck of network application, and the arrival of FTTH has led people to enter the era of optical fiber access. Its advantages in bandwidth make it an ideal direction of network access in the future. At present, the design of FTTH fiber core routing is not scientific, which makes people have a great obstacle in the later maintenance. The use and maintenance of fiber core routing is extremely time-consuming and labor consuming, and the accuracy of judgment is low, which often leads to repeated investment. On the basis of analyzing the characteristics of FTTH core routing and considering the utilization ratio and weight of fiber core, an improved ant colony algorithm based on rotation model is designed in this paper, which combines the characteristics of ant colony algorithm. It provides a new theoretical idea for FTTH core routing design, core routing lookup, core routing expansion, core routing repair and so on. Based on the research of FTTH construction mode and structure, this paper discusses the core routing strategy of FTTH with a case of a residential area. The main task of this paper is to simulate and compare the FTTH fiber core routing with ant colony algorithm based on rotation model considering weights. The results show that the improved core routing ant colony algorithm takes account of weight value in resource utilization. Maintenance efficiency and other aspects provide more intelligent advantages, can to a certain extent for the FTTH core route pre-allocation, reducing the FTTH users in the route exploration time, It also provides a theoretical reference for later FTTH user maintenance and core routing expansion. The main work of this paper includes: 1. The method of core rotation model is introduced. According to the characteristics of FTTH core routing concept, a core routing rotation model is designed to manage and control fiber core routing better. Combination analysis of ant colony algorithm and weight. According to the relationship between fiber core characteristics and fiber depletion, the concept of weight is divided independently, and the set of ant colony algorithm makes it more prominent in the complexity of the ant colony path and the importance of the weight concept in the core. The core routing analysis and comparison of ant colony algorithm based on rotation model. Comparing with some common routing algorithms in FTTH core routing direction, we can see the advantage of ant colony algorithm based on rotation model. The simulation and analysis of fiber core routing fault judgment are discussed with an example of FTTH. According to the current situation of FTTH in a certain cell of a telecom branch, the core routing analysis and comparison are carried out based on the ant colony algorithm based on rotation model.
