Mail Server, Cloud Server, Cloud Zoro Application, Using P2P File Sharing

People are using P2P (Peer to Peer) network for sharing and transferring digital content containing video,audio, or any other data file over the internet from different part of the globe. All General P2P file sharing protocols were designed to work optimally in the case that all the peers have an end node on the internet i.e. they are connectible. But due to the huge number of computers behind NAT1 and proxies this is rarely achievable. Due to this, the load is unevenly distributed between the connectible and nonconnectible peers, and non-connectible peers usually suffer from slow download speeds, while connectible users suffer from too many uploads. In the case that all the peers are not connectible it is not possible to use P2P at all. An approach called Mailzoro was presented entirely new p2p protocol which takes care of the deficiencies in P2P protocols. Low number of IPv4 addresses, hosts behind NAT, and the asymmetric property of broadband connections make most P2P protocols inefficient. Mailzoro an email based P2P file sharing protocol which would be a huge improvement over the existing P2P networks since every node would be reachable, and it would be possible to send a file to multiple users without uploading it multiple times. And moreover if we use systems like Gmail and Yahoo then most of the mails would be transferred internally and much more efficiently, thus improving the overall efficiency of the internet. In this project we present CloudZoro which overcomes the overhead imposed on the peer's for checking the availability of the file pieces in the mail server periodically, which may degrade the performance of low end devices, via cloud messaging we reduce the communication overhead which increases the performance by 90%. The above approaches provided the p2p file transfer but didn't solve the node reachability problem and processing overhead on the clients. The proposed approach Cloud Zoro provides an approach that solves the peer's reach ability and the processing overhead using the cloud server.The cloud's push to device messaging allows clients and the file peer's to the transfer the message as they become reachable. The Cloudzoro approach improves the performance of the application by 90% compared to other approaches.
