| 中文摘要: |
| Internet 流量模型对网络性能管理、QoS、准入控制等都有很重要的意义和作用.首先总结了现阶段已发现的主要网络流量的特性及相关度量参数,概要地介绍网络流量建模的意义和分类,然后按照“传统-自相似-流量建模的新发展”这3 个阶段阐述网络流量建模的发展历程与最新的研究成果,最后针对目前网络流量建模中存在的难点问题,展望了该领域未来的研究发展方向. |
| 英文摘要: |
| The Internet traffic model is the key issue for network performance management, Quality of Service
management, and admission control. The paper first summarizes the primary characteristics of Internet traffic, as well as the metrics of Internet traffic. It also illustrates the significance and classification of traffic modeling. Next, the paper chronologically categorizes the research activities of traffic modeling into three phases: 1) traditional Poisson modeling; 2) self-similar modeling; and 3) new research debates and new progress. Thorough reviews of the major research achievements of each phase are conducted. Finally, the paper identifies some open research issue and points out possible future research directions in traffic modeling area. |
