AIMAIM

To develop PEER-TO-PEER STREAMING

using distributed overlay framework called SMESH

to achieve low delay and low link stress.

AGENDAAGENDA• Existing System.

• Problems.

• Proposed System.

• P2P system and streaming.

• Dynamic randomization group.

• Smesh.

• Delaunay triangulation

• System architecture & Use case diagram.

• Conclusion and bibliography.

EXISTING SYSTEMEXISTING SYSTEM

• Centralized systems.

• Whole data.

• Frames with delay.

• peers dynamically hop from one group to another.

• efficiently deliver specific contents to peers.

PROBLEMSPROBLEMS

Broadcasts all contents to all hosts

inefficient end-to-end delay

a separate and distinct delivery overlay for each channel.

high control overhead

PROPOSED SYSTEMPROPOSED SYSTEM

• Peer to peer.

• Frames with less delay.

• Stable mesh consisting of all hosts.

• Group peers corresponding to each channel.

• Dynamic host joining and leaving.

PEER-TO-PEER SYSTEMSPEER-TO-PEER SYSTEMS

• Smesh.

• Control messaging.

• Unicast connections.

• Multiple channels

• A single shared overlay mesh

• Loop detection and elimination.Tuesday, April 11, 2023 11

DYNAMIC RANDOMIZATION DYNAMIC RANDOMIZATION GROUP GROUP • Packet transmission

• The randomized pickup

• Broadcast all contents

• End-to-end delay

• Distinct delivery overlay

• High control overhead Tuesday, April 11, 2023 13
