Abstract

Software Defined Vehicular Networks (SDVN) brings a set of attractive features to vehicular networks along with an upgrade in the performance. Yet, SDVN suffers from frequently compelling to contact the centralized control plane, which in turn generates a high latency and packet overhead in the communication. The current solution to reduce the delay, proactive approach, does not bring the packet overhead down and impose a lot of stress on the controller with a decline of Packet Delivery Ratio (PDR). As an alternative, we introduce a source routing based flow instantiation operation with intelligent route caching that reduces the extent of communication with the control plane, but still manages to utilize the knowledge of controller while maintaining a lower latency and packet overhead.
软件定义车辆网络中基于源路由的高效流实例化
软件定义车辆网络(SDVN)为车辆网络带来了一系列吸引人的特性,并在性能上进行了升级。然而,SDVN经常被迫与集中控制平面联系,这反过来又在通信中产生高延迟和数据包开销。目前减少延迟的解决方案是采用主动的方法,这种方法不仅没有降低数据包开销,而且对控制器施加了很大的压力,导致数据包投递率(packet Delivery Ratio, PDR)下降。作为替代方案,我们引入了一种基于源路由的流实例化操作,该操作带有智能路由缓存,减少了与控制平面的通信范围,但仍然设法利用控制器的知识,同时保持较低的延迟和数据包开销。
