【摘要】：随着经济的发展,人们对带宽的需求也不断的增长,ADSL已经成为网络应用的一种瓶颈,而FTTH的到来引领人们进入光纤入户的时代,其在带宽方面的优势使得它成为未来网络接入发展的理想方向。目前FTTH纤芯路由的设计缺乏科学性,让人们在后期的维护中产生了很大的障碍,纤芯路由的使用与维护极其耗时耗人工,而且判断准确率较低,经常引发重复投资。本文在分析FTTH纤芯路由特点的基础上,充分考虑光缆纤芯利用率及权重,结合了蚁群算法的特点设计了一种基于旋转模型的改进蚁群算法。为其在FTTH纤芯路由设计、纤芯路由查找、纤芯路由扩容、纤芯路由抢修等方面提供了一种新的理论思路。论文在研究FTTH建设模式及结构的基础上以某小区案例探讨了FTTH纤芯路由策略。主要任务是考虑权值情况下基于旋转模型的蚁群算法对FTTH纤芯路由进行脆测及路由探索仿真比较,结果表明考虑权值情况改进的纤芯路由蚁群算法在资源利用、维护效率等方面提供更为智能化的优势,可以在一定程度上对FTTH纤芯路由进行预分配,减少了FTTH用户在路由方面探索的时间,也为后期FTTH用户的维护与纤芯路由扩容等提供了理论参考。本文的主要工作包括：1.引入了纤芯旋转模型的方法。根据FTTH纤芯路由概念的特点,设计了纤芯路由旋转模型,使其更好的进行纤芯路由的管理和控制。2.蚁群算法与权重的结合分析。根据纤芯特点与光纤衰耗的关系,将权重概念独立划分,与蚁群算法的集合使其更加突出在蚁群路径上的复杂性与纤芯中权重概念的重要性。3.基于旋转模型的蚁群算法的纤芯路由分析与对比。与常见的几种路由算法在FTTH纤芯路由方向的对比,可以看出基于旋转模型的蚁群算法的优势。4.用实例FTTH讨论纤芯路由故障判断的仿真与分析。根据某电信分公司某小区FTTH的现状,结合基于旋转模型的蚁群算法进行纤芯路由分析和对比。
[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.
