To transfer files between computers on a local network, there are several options available. One common choice is to use a USB stick or an external hard drive. Alternatively, one could set up a dedicated home file sharing server like the MyCloud Server by Western Digital, or even repurpose an old computer into a file sharing server using the SMB protocol. Another option is to subscribe to a cloud-based file sharing programme. However, what all the above-mentioned options have in common is the need to buy additional hardware or fees that we must pay in order to achieve the same result – file sharing.
With the diploma thesis, that lies in front, we decided to create a purely web-browser-based file sharing system; a system that needs only two users with two computers that are connected to the same LAN – Local Area Network and are able to run the provided website.
In the results section we will later look at the efficiency of the created system in comparison to some of the already existing solutions – mainly a standard SMB server, that would in our case work as a middleman in the exchange of data.
The results have shown us the main advantages of the designed system. Unlike SMB technology, in our browser-based application we were able to transfer files between two peers without the need of additional external storage (as you would need for cloud storage sharing). The connection itself was also encrypted (packets were transferred using the DTLS protocol), which contributed to the cyber security of the system itself.
