Brihaspati-3

• Started13 years back – to support our own

classroom teaching

• Based on Turbine framework, uses Torque and

Velocity frameworks

• Code distribution via

http://sourceforge.net/projects/brihaspati

• Opensource – liberal license – anybody can

make commercial or non-commercial reuse – acks and disclaimers for the used code to be retained.

• Feedback from users – faculty and students –

used for evolution of design.

• Interns, students, project staff (funded by DeitY,

MHRD) contributed to the code.

Developmental philosophy

• Fixs bugs at highest priority.
• Feature enhancements next
• Release as early as possible (like many other
• pensource projects)
• Worry about functionality first, GUI later.
• Pareto principal 20% code used 80% of the

time.

• Focus on 20% of the important code

• Faster development- usable by most of the

people.

• Design evolution – users participant in the

design process, testing

NMEICT impact

• Converted the design to act as National Service

(now available from brihaspati.nmeict.in)

• Institute can take area on the system.
• Institute admins (can be many) – manages

thereafter.

Many other systesm

• Built as components
• BrihaspatiSync – p2p live lecture streaming

system

• BGAS – Brihaspati General Accounting System

Future

• Brihaspati-4 P2P system
• Storage (content sharing)
• Streaming
• Search
• Messaging

– One person – Friends – Groups – Anyone following

• Sandbox VM

• Hybrid of structured and unstructured P2P

framework

• Advantage – scalability of massive numbers
• Certificate signing server
• Seeding (bootstraping mechanism) server

Challenges

• Reputation Management Systems
• Security mechanisms
• NMS to monitor p2p overlays
• Reliability
• Disconnected operations
