摘要:
随着互联网技术及其应用的发展,SDN(software defined networking,软件定义联网)网络需求和服务的不断扩大,导致域间网络管理的局限性越来越明显.为了给跨越多个SDN管理域的服务提供商提供有效和灵活的网络资源管理,提出了一种基于SDN技术的跨域服务协商方案.不同管理域的SDN控制器可以为特定服务请求进行服务参数协商,并形成服务等级约定.基于OpenDayLight开源控制器平台设计和实现了相关原型系统,服务提供商中的SDN控制器通过SDN支持的应用编程接口,可以通过逐流的方式明确地向网络提供商发出快速和慢速通道的请求.实验结果表明,在跨越多个SDN管理域时,使用这种服务协商方案能有效地降低流量转发数量,提高服务质量,并对具有服务需求的SDN网络应用提供支持
Abstract:
With the development of Internet technology and its application,and the continuous expansion of network requirements and services of SDN (software defined networking),the limitations of inter-domain network management are increasingly obvious. In order to provide an effective and flexible network resource management for service providers spanning multiple SDN management domains, we propose a cross-domain service negotiation scheme based on SDN technology. SDN controllers from the different management domains can negotiate the service parameters for the specific service requested,and form a service level agreement. Based on the OpenDayLight open source controller platform,a related prototype system is designed and implemented. Through the application programming interface supported by SDN,the SDN controller in the service provider can send requests of fast and slow channels to the network provider in a streaming manner. The experiment shows that the proposed scheme can effectively reduce the number of traffic forwarding and improve the service quality,and can provide support for the SDN network application with service requirements when crossing multiple SDN man- agement domains.
