Tutkittavia tekniikoita olivat HTTP Polling, HTTP Long Polling, Server-Sent Events, HTTP Streaming ja WebSocket. Tutkimuksessa toteutettiin viestisovellus jokaisella tekniikalla.

Tulosten perusteella WebSocket on selke\u00e4sti tehokkain tapa toteuttaa reaaliaikaisia web-sovelluksia.

Nowadays, web technologies have evolved so much that the most advanced web applications can be developed using only native browser technologies. Many desktop applications have been moved to the web and real-time capabilities have increased in web applications a lot. The aim of this work was to compare the most popular techniques used to achieve real-time data flow. The techniques were HTTP Polling, HTTP Long Polling, Server-Sent events, HTTP Streaming and WebSocket. A real- time messaging application was implemented witch each of the techniques. Package sizes were compared between the real-time techniques and load tests were performed for the server side applications. Results indicate that the WebSocket is clearly the most efficient technique to develop real-time web applications. HTTP Streaming and Server-Sent Events were pretty much the same when comparing the results, but that was expected.
