Research In The Core Routing Strategy Base On FTTH

With economic development, people’s demand for bandwidth is growing constantly, ADSL has become a bottleneck in network applications, and the arrival of FTTH fiber to the home to lead people into the era of its advantages in terms of bandwidth makes it become a future network access the ideal direction. FTTH is currently a lack of core routing design science, so that people had a lot of obstacles in the latter part of the maintenance, use and maintenance of the core routing is extremely time-consuming and labor, but also to determine the accuracy rate is low, often lead to duplication of investment.Based on the analysis on FTTH core routing features, utilization and fully consider the weight of the cable core, combined with the characteristics of ant colony algorithm is designed to improve the rotation model-based algorithm. FTTH route lookup in its core routing design, core, core routing expansion, repair and other aspects of the core routing provides a new theoretical ideas.FTTH construction paper in basic research on the structure of the model and to investigate the case of a residential FTTH core routing strategy. The main task is the case under consideration the weights rotate the model based on ant colony algorithm for FTTH core routing monitoring and routing explore comparative simulation results show that the situation considering the weight of the core routing ant colony algorithm to improve the resource utilization, maintenance, efficiency, etc. offers the advantage of a more intelligent, to a certain extent, pre-allocated FTTH core routing, routing reduces the FTTH users in the exploration of time, but also for the late FTTH subscribers routing maintenance and expansion of the core to provide a theoretical reference.The main work of this paper include:1 introduces the core rotation model approach. According to the characteristics of FTTH core routing concept, design core routing rotate the model so that it better be the core routing management and control.2 heavy ant colony algorithm and the right combination of analysis. According core optical fiber attenuation characteristics and the relationship between the weight of the concept of independent division, with a collection of ant colony algorithm to make it more prominent importance in the colony path complexity and weight of the fiber core concepts.3 core routing based on ant colony algorithm analysis and comparison of the rotation model. Contrast with the common core of several routing algorithms in FTTH route directions, you can see the advantages of ant colony algorithm rotation model.4 Simulation and Analysis discussed with examples FTTH core routing failure of judgment. According to a telecommunications branch of a small FTTH status area, combined with the analysis and comparison of conduct core routing algorithm based on ant colony rotation model.
