With a san , there is no need for a physically separate network because the san can function as a virtual subnet operating on a shared network infrastructure , provided that different priorities or classes of service are established 有了存储区域网，就不需要物理上分开的网络，因为只要建立了不同的优先等级和服务种类，存储区域网就起了在一个共享的网络基础设施上运作的虚拟子网的作用。
Planning and scheduling satellite ' s payloads is to arrange the working mode of payloads under the limited resource on satellite , optimize the scheme of resource . the related theory and application with planning and scheduling technology are introduced firstly 在卫星资源受限时，规划与调度应该能够根据有效载荷的优先等级、资源请求和卫星的资源情况，合理安排各个载荷的工作状态，在满足各种资源约束的前提下最大限度的获取科学数据。
In the border router , we design a new diffserv scheduler ( bswcs : bit - based weight time slot compensate scheduler ) , which dynamically adjust the weighted quantum of service . combined with the error concealment technology in the video decoder , in case of severe congestion which cause losing a lot of ip packets , these algorithms have been proved effective , hence the delay , jitter and the perceived picture quality all meet requirement for real - time video transmission 4建立了一个区分服务网络模型,根据视频编码的特点,提出了一种针对视帧传输的新的服务优先等级标识算法,即根据不同视频帧解码时的重要程度和网络的传输状况将不同视频帧的数据包标记为不同等级,赋予不同的质量保证。
