Next Generation Network: Optimised Video Casting – Phase 3

Project Members :

Sha Jing Long Alvin

===========================================
Project Introduction :

• Using the modern technology of networking to create the Next Generation Optimized Video Casting Network and the implementation of video using multiple casting.

Project Scope :

• Produce a way to have LIVE broadcasting on surrounding and and thing that we want to know but we are unable to see.
• Produce and stream LIVE broadcasting across multiple computers.Example,streaming of movie video to multiple computers so as every computer will be ruining at the same time.

Project Objective :

Development of Linux-based multi-casting-multi-streaming video channeling system based on Triple Play modeling,where system can allow incorporation of Voice and Data simultaneous transmission at the same time maintain Quality of Services (QOS).

Project Description :

• Understanding phase 1 and 2 of Next Generation Network that thee seniors have done. This includes online research on IP Multi casting and video streaming.
• Experiment with setting up the next generation network model .
• Conduct one to one video streaming and eventually if it succeeds,they will be streaming one to many video streaming.

Project Charter :

IP Multi Cast:

• A technique for one to many communication over an IP infrastructure to scale a larger receiver population by not requiring prior knowledge of who or how many receivers there are.
• Multi cast uses network infrastructure efficiently by requiring the source to send a packet only once, even if it needs to be delivered to a large number of receivers.
• Nodded in the network to take care of replicating the packet to reach multiple receivers only where necessary.
• Key concepts of IP Multi cast include an IP Multi cast group address, a multi cast distribution tree and receiver driven tree creation.

Multi Cast Diagram :

Uni Cast:

• In computer networking, uni cast transmission is sending of information packets to a single destination.
• Used by streaming content providers' services.
• Uni cast servers provide a stream to a single user at a time, while multi cast servers can support a larger audience by serving content simultaneously to multiple users.

Uni Cast Diagram: Problems Encountered:

• Insufficient Equipment (Cross-Over cable)
• Software bugs (FireFox, Chrome, Windows XP, Linux Ubuntu, VideoLAN (VLC) )
• Linux Ubuntu configuration
• Catalyst 3550 SERIES-CORE Switch bug

Overcoming Challenges :

1. Research from library and on the Internet.
2. Counsel Supervisor for guidance.
3. Tried every means with trials.

Conclusion:

In This three months,they have learn new debugging method to handle software bugs,real life working experiences and learn the importance of teamwork to ensure the project run smoothly.
