中文摘要：
针对目前内容中心网络在Qo S保证方面研究不足的问题,提出一种基于内容感知传输机制的内容优先级调度算法。该算法利用内容热度值判决内容数据包的优先级概率决定不同内容的调度顺序,能够根据网络环境动态调整传输队列。仿真结果表明,该机制在高优先级内容流量比例为20%的情况下,平均吞吐量相比于NDN常规传输机制性能提高约35%。
英文摘要：
Based on the current insufficient research on Qo S guarantee in content-centric networking,this paper put forward content-aware-based transmission mechanism in network layer to specific application layer and content priority scheduling algorithm. Content priority scheduling algorithm judged priority of content packets by content heat values to decide scheduling order,and adjusted transmission queue according to the dynamic network environment. The simulation results show that the average throughput increases by about 35% compared with NDN transport mechanism under the condition of 20% high priority content flow.
