15. High Resolution visualization in
science-1
 The scientific visualization needs –high speed large
volume optical transport and high quality digital media
services .
 It requires 2-steps implementations
 Step-1. Design the network for scientific
visualization
- In order to design and operate the optical network for
scientific visualization application , a set of system
management process is required to provide device
locations ,resource balancing and communication
management .
- It also requires multiple components , processes and
timing among processes .

16. High Resolution visualization in
Science -2
 Step-2.Do experiment with reach digital
media in HPDMN Global network
environment .
- HPDMN-high performance digital media network .
- It’s a global large scale distributed environment that
has designed and implemented to support large scale
scientific visualization .
- It uses open source scalable adaptive graphics
environment (SAGE) system to support visualization.

 The delivery of real time multimedia contents consists
of 3-primary functions
 Media productions /compositions
 Adaptions
 Delivery /Distributions
 When the multimedia contents need to be delivered to
multiple end devices , it mainly requires adaptions to
