INTRODUCTION
A number of commercial peer-to-peer systems for live streaming have
been introduced in recent years.
Zattoo is one of the largest production live streaming providers.
It has about 60000 concurrent users on a single channel but still
maintains a delay for just 2 to 5 sec.

Before going to know more about our project lets first know some
terms
Peer –to-peer(P2P) network is a distributed application
architecture that partitions tasks workloads
among peers.

PROBLEM STATEMENT
This can be easily explained using the 5 ‘W’s concept
• Who does the problem affect? Live stream viewers
WHO
• What is the issue? Delay in channel switching
WHAT
• When does the issue occur? Flash crowd scenarios
WHEN
• Where is the issue occurring? field of live streaming in IPTV
WHERE
• Why is it important to fix the problem? To reduce delay

11. IEEE/ACM TRANSACTIONS ON NETWORKING, VOL. 19, NO. 1, FEB 2011
Increase in the passion for live stream viewing resulted in
the increased no. of viewers , pressurizing the servers
causing large delays. Hence the concept of peer division
multiplexing came in to existence to reduce the delay.

EXISTING SYSTEM
Tree- based systems
The video source server is
connected to all users
participating in the session by a
multicast tree .
Disadvantages

PROPOSED SYSTEM
As packets from each sub-stream arrive at the peer, they are stored in the IOB
(packet buffer)for reassembly to reconstruct the full stream.
IOB is used by
1) Local media player .
2) Local file if recording is supported.
3) Other peers.
Repeater nodes are allocated to improve the uplink bandwidth,which acts
as a bandwidth amplifier.
Retransmission helps a peer recover from transient
network congestion..

Real-time constraints requiring timely and sustained streaming delivery to all
participating peers
Performance-demanding involving bandwidth requirements of hundreds of
kilobits per second and even more for higher quality video
Large-scale and extreme peer dynamics corresponding to tens of
thousands of users simultaneously participating in the streaming with highly
peer dynamics (join and leave at will)
especially flash crowd

Live Data Streaming
The Zattoo system rebroadcasts live TV, onto the Internet.
The system carries each TV channel on a separate peer-to-peer
delivery network
Join only one peer-to-peer network at any one time.

Peer-division Multiplexing
Building a virtual circuit to each of the
neighboring peers.
Maintaining virtual circuits, each
packet is forwarded without further
per-packet handshaking between
peers.
Storing packets in the IOB for
reassembly to reconstruct the full
stream.
Playback reconstructed parts of
stream

Search Phase
Joining peer sends out a SEARCH message .
The SEARCH message contains the sub-stream indices.
The substream indices is usually represented as a bitmask of n bits,
where n is the number of sub-streams defined for the TV Channel.
Join Phase
joining peer sends JOIN requests to each potential neighbor.
The JOIN request lists the sub-streams for which the joining peer
would like to construct virtual circuit with the
potential neighbor.
Spread out the load amongst the peers and
