Optimizing File Replication Over Limited-Bandwidth Networks Using Remote Differential Compression

Overview Remote Differential Compression (RDC) protocols can efficiently update files over a limited-bandwidth network when two sites have roughly similar files; no site needs to know the content of another's files a priori. This paper presents a heuristic approach to identify and transfer the file differences that is based on finding similar files, subdividing the files into chunks, and comparing chunk signatures. The work significantly improves upon previous protocols such as LBFS and RSYNC in three ways.

Windows worm now spreading

MSBlast installs the Trivial File Transfer Protocol (TFTP) server, and runs the program to download its program code to the compromised server. The component, known as the remote procedure call (RPC) process, facilitates activities such as sharing...

Will IP unify communications?

While heavyweight applications from the likes of Siemens, Nortel and others allow this kind of thing, free applications such as Skype also allow instant messaging, file transfer and conferencing calling, as well as basic one-to-one calling.

Is BitTorrent moving into the mainstream?

The A to Z of security

And because signatures are seen as an increasingly outdated defence - by their very nature they are behind the threats - many AV vendors are producing more predictive technologies based on smarter analysis of data to second-guess potential threats...
