提出并描述了一个实时业务重叠网系统(RSON).它由一组业务结点构成,这些结点分布在Internet上,并由业务链路连接起来,从而在现有的IP网络上形成一个虚拟的传输重叠网.RSON的最大特点在于,它不需要对现有的网络层协议做任何修改.为了能够为每条业务流提供所需的服务质量保证,RSON中每个业务结点都参与一个分布式重叠网业务路由协议(OSRP)以协同工作,它包括业务链路状态的测量、链路状态信息的分发、业务路径的选择和建立,以及相应的数据包交换模块.作为覆盖在现有底层网络上的虚拟传输网,RSON使得业务提供第三方能够在Internet公网上提供自己的增值业务,因此以IP语音通信为例说明如何利用RSON在Internet上提供增强的网络服务,并指出它的优点所在.
A real-time business overlay network (RSON) is proposed and described, which consists of a set of business nodes that are distributed over the Internet and connected by service links to form a virtual network over the existing IP network Of the transmission overlay network.RSON the most important feature is that it does not need to make any changes to the existing network layer protocol.In order to be able to provide each service flow required quality of service assurance, RSON each business node to participate in a Distributed Overlaying Service Routing Protocol (OSRP) to work together, including the measurement of the status of the service link, the distribution of link status information, the selection and establishment of the service path, and the corresponding packet switching module, The bottom of the network virtual transmission network, RSON enables business to provide a third party to provide their own value-added services in the Internet public network, so using IP voice communications as an example shows how to use RSON to provide enhanced network services on the Internet, and pointed out its advantages Where you are.
