[Planetlab-users] CoDeploy service

[KyoungSoo Park]

Hi Planetlab users,

We'd like to announce a new service on Planetlab.  It's called
CoDeploy, and attached below is a short description about what it
does.  It's an efficient parallel file copying tool which is useful
for installing content and keeping it updated without using much
bandwidth at the origin.  More information can be found at
http://codeen.cs.princeton.edu/codeploy/.

Thanks,

CoDeploy provides an efficient and scalable means to distribute
content from one source to many receivers.  In practice, what this
means for PlanetLab is that it allows you to push content to hundreds
of PlanetLab nodes without having to consume lots of bandwidth at the
source.  In detail, CoDeploy uses the CoDeeN service as a content
distributor, finds the nearest healthy CoDeeN proxy for each
individual receiver and downloads only modified content from the
source.  In the case of large files (even files that are hundreds of
megabytes), CoDeploy splits them into small pieces and has multiple
CoDeeN proxies deliver each chunk to a destination to enhance the
cache locality and the latency. It enables you to have your content up
to date on all the nodes you want in a fast and intelligent way.
