BIGSPEED Peer-to-Peer SDK

The reinvention of peer-to-peer for private use

Version 3.0 - May 9, 2008
Idea
Peer-to-peer technology, the ability to work with and share files directly from computer to computer, is one of the latest buzzes in the computer industry. Unfortunately, the term "peer-to-peer" has quickly become a synonym for copyright infringement.
We want to create a virtual private peer-to-peer network for small groups, typically up to a hundred of desktops. Based on a physical clent/server technology, our SDK must build virtual peer-to-peer network.
Architecture


Design
Building a virtual private Peer-to-Peer community
NAT and Firewall friendly
A direct connection between two peers is not necessary, instead a permanent virtual circuit is established. The hub relays all the packets traveling between peers.
On-the-fly 128-bit AES encryption with random session keys
Peer authentication at protocol level with digital fingerprints or secret keys
Peer authentication at application level with username/password
Symmetric encryption mode with shared secret key
Asymmetric encryption mode with 1024-bit Public/Private keys
Binary data transfer (array of bytes) between peers
Binary data transfer (array of bytes) between peers and the hub
Instant alert messaging
Instant chat messaging
All standard FTP operations - download, upload, rename, delete, etc.
On-the-fly transparent file compression
Remote file ant full text search
