VodUdpServer¶

//
// Models the transmission of a video-on-demand (VoD) stream over UDP.
// The input is taken from a specified trace file, representing a video encoded
// according to the Scalable Video Coding (SVC) standard. Each line of the trace file defines
// the size and transmission time of a video frame.
//
