基于元能力的网络柔性服务机理探析
|
摘要
针对传统网络在灵活性、可扩展性等方面存在的缺陷,对元能力和元服务的基本性质和基本理论进行了阐述,提出了一种基于元能力的网络柔性服务机理,该机理通过网络元能力的建模和动态组合,可灵活构建网络服务链和服务路径。通过服务链的灵活组合和部署,在节点层面实现了网络功能的灵活定义;通过服务路径的灵活定制,实现了网络服务多样性与动态性的结合,最终实现网络柔性服务。
Aiming at the defects of traditional network on flexibility and extensibility,this paper proposes a novel flexible network service mechanism based on atomic capacity. By implementing the modeling and dynamic combination of network atomic capacity,the network service chain and service path can be constructed flexibly.Based on flexible combination and deployment of service chain,the real-time dynamic adjustment of network function can be realized. Based on flexible customization of service path,the combination of network service diversity and dynamics is implemented so as to realize the flexble network service.
