Abstract

A packet scheduling method and apparatus with the knowledge of application behavior, anticipated usage/behavior based on the type of content, and underlying transport conditions during the time of delivery, is disclosed. This type of scheduling is applicable to a content server or a transit network device in wireless (e.g., 3G, WIMAX, LTE, WIFI) or wire-line networks. Methods for identifying or estimating rendering times of multi-media objects, segmenting a large media content, and automatically pausing or delaying delivery are disclosed. The scheduling reduces transit network bandwidth wastage, and facilitates optimal sharing of network resources such as in a wireless network.
