Description

目前的视频业务以及 Web浏览为基于脉冲 Burst的业务,比如通过客户端 点击某个链接, 发起超文本传输协议 ( Hyper Text Transfer Protocol, HTTP ) 请求以获取网页, 则需在客户端收到一个窗口的所有数据包 (即一个 Burst ) 之后, 才能完整呈现。
目前链路层的调度位于媒体接入控制 (Media Access Control, MAC )层, 为基于包的调度。 为保证用户体验, 通常调度会为每个包设置时延限制, 即对 于该 Burst的每个包都需要在该时延限制范围内传输。 然而, 对每个包都设置 时延则限制了调度的灵活性。而且, 因 Burst的时延不仅与每个包的时延有关, 还与带宽有关, 即使每个包都满足时延限制, 也不一定能保证整个 Burst的时 延, 传输效率较低。 发明内容
