The State of the Code

So the programming has begun in full swing.  There is already a good start to the network clients for the Meta Data Controller, MimirClient(the “user” client) and the Storage Client.  Also a SubVersion repository has been set up and can be viewed on our Trac page at http://compsciguy.homeftp.org/trac/mimir.  Also i want to take this time to thank Chris Deeterly for his suggestion to implement a task handler that works like a queue to process tasks. The deadline is coming up soon (feb 11th) and we are working at a fever pitch to get this first HUGE milestone done in time.

Distributed Hash Tables

Today i had an appifiny, after meeting with my advisor i discoverd the optimal way for the network to work and i beleve a solution that will let me impliment it.  That methood is DHT and the solution is Bamboo .

DHT’s are the appropriate solution becasue they will allow our project to maintain some structure withought needing to broadcast the entire file to all nodes.  Also DHT’s provide a network overlay, routing algorithums and a network protocall.  This simplifies my work from the privious approch wich was to use Nemo which would only provide a network overlay.

Bamboo is great because of it’s simple protocol of Get and Put as well as it’s efficiency in handling changing networks with high churn(or nodes leaving and joining often).  It is also Open-source under the GPL and  very modular for the changes we will make.

Current concepts are to have a hash key for each block and use these hash keys as channels for data transfer.  More information on this later.
