| 摘要: |
| 针对传统电力通信网络路由效率低、成本开销大等缺点，在软件定义网络的基础上，提出了一种基于改进蚁群算法的电力通信网络QoS路由策略。建立了以时延、路径数和抖动等为约束条件的路由模型，并使用改进的蚁群算法进行路径选择。通过仿真和传统路由策略进行端到端延迟、丢包率和链路利用率等性能比较。结果表明，相比于传统策略，该策略的负载分布更加均匀，在端到端的时延、丢包率、链路利用率等性能上都有明显提高，具有一定的实用性。 |

| Abstract: |
| There are some shortcomings of traditional power communication network, such as low routing efficiency and high cost. Thus a QoS routing strategy based on an improved ant colony algorithm is proposed on the basis of a software defined network. A routing model with delay, number of paths and jitter as constraints is established, and an improved ant colony algorithm is used for path selection. The end-to-end delay, packet loss rate and link utilization are compared by simulation and traditional routing strategies. The results show that, compared with the traditional strategy, the load distribution of the strategy is more uniform, and the performance of end-to-end delay, packet loss rate, link utilization and so on are significantly improved. This suggests good potential for practical application.
