Introduction
• Video streaming is an important multimedia application
• After the emergence of MPEG-4 video standard, video
streaming applications are expected to grow [2].
• Video streaming requires some QoS guarantees [3]
•

•
Latency of start (LOS)
Packet Delay
Packet Loss
Magnitude of Reservation of Bandwidth
• Bandwidth is a scarce resource on the Internet
• Trade-off between quality of video and bandwidth
allocation for video streaming
Video Stream on IP
• Internet was not designed for multimedia streaming
• It is a shared medium and uses a best effort delivery
mechanism i.e. Internet Protocol (IP) to deliver content
• With respect to the real-time nature of video streaming,
inconsistent bandwidth, latency, noise, packet loss,
retransmission and out of order packet delivery are the
problems that can affect video streaming over the
Internet [4].
• Many research studies were conducted to provide some
QoS guarantees for MPEG-4 video streaming [5], [6] and
[7]
Video Stream on IP (cont…)
• Most of the studies ([5] and [8]) concentrate on
• source rate adaptation,
• packetization,
• feedback control, and error control
• Some research [9] studies implement
• source based rate control system,
• synchronization layer packetizer and a
• signaling mechanism
to improve the delivery mechanisms of MPEG-4 video
over the network.
Video Streaming on ATM
• ATM provided an architecture for QoS-based services
• In ATM networks, VBR coding schemes can be used in
principle without sacrificing bandwidth-utilization
efficiency [9]
• Researchers [9] investigated the performance of various
algorithms to predict the bandwidth allocation
requirements for MPEG video coders based on
• peak cell rate (PCR)
• sustainable cell rate (SCR)
• maximum burst size (MBS)
Video Streaming over MPLS
• MPLS is a recent network technology that transmits
traffic effectively and supports QoS on the Internet [18]
• In MPLS, a Label Switched Path (LSP) is setup with
certain QoS guarantees using LDP or RSVP-TE
• Researchers [1] have studied the performance
enhancements of video streaming over MPLS network by
using Constant Bit Rate (CBR) and Constraint-Routing
Label Distribution Protocol (CR-LDP) protocol
Video Streaming over MPLS (cont.)
• A Study on the Performance Enhancements of Video
Streaming Service based on MPLS Networks
Joong-Min Kim, Chung-Hyun Kim
 Performed simulation based study of video streaming by
allocating the bandwidth for the maximum frame size.
 Compared delay, throughput and packet loss of video
streaming service over IP network and MPLS network.
 CBR MPEG-4 video streams using CR-LDP, CQ and LLQ for
traffic reshaping mechanism.
• My project is to evaluate various network parameters
with VBR video over MPLS with RSVP-TE for LSP
setup
Simulations
• Traces of various video sequences [22] with their
statistics.
• Tools for simulations
– J-Sim [24] is a component based network simulator developed
entirely in Java
– OMNeT++ [26] is a discrete event simulation environment
programmed in C++ and developed by András Varga
– NS-2 (Network Simulator 2) is a discrete event simulator targeted
at networking research [31]
