SDN与流量精细化运营

SDN and Traffic Fine Operation

在分析网络流量疏导和优化多个案例的基础上,提出了一种通过SDN控制叠加网络来进行业务流量管控的思路和系统框架,该方案可以根据用户指定的策略对流量进行智能调节,可以被广泛应用于多种类型的IP网络,并可以有效利用成熟的协议和架构,支持现网平滑演进到SDN。

On the basis of analyzing the real use cases of network traffic optimization, an idea and system architecture were presented, which abstracted the current network to the overlay network and used the SDN controller to control the overlay network for smart traffic steering and optimization according the policies defined by users. This solution can be widely applied in multiple different type of IP networks, and utilize the mature protocols to migrate the existed network to SDN smoothly with the benefits from SDN.
