Design and Implementation of PTP (picture transfer Protocol) interface and a generic interface between CEDs and the BlueFS.

I worked on BlueFS – a distributed energy-efficient file system developed at University of Michigan, and developed a PTP interface for the file system and a digital camera so that all the changes on the file system or the camera are asynchronously and automatically replicated over the network. I also developed a generic interface for BlueFS which enables it to interact with different Consumer Electronic Devices (CEDs) having different protocol supports.
