Name	Type	Description
VoDUDPServer	simple module	This module 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.
