Abstract [sv]

Denna rapport beskriver ett examensarbete utfört vid Skolan för informations- och kommunikationsteknik på Kungliga Tekniska Högskolan i Stockholm.

Rapporten behandlar WebSocket som är ett nytt kommunikationsprotokoll som främst är framtaget för att förbättra prestandan inom webbkommunikationen. WebSocket är tänkt som ett substitut till HTTP inom områden som kräver låg responstid och asynkron uppdatering. WebSocket stöds idag av alla moderna webbläsare och har standardiserats av W3C (World Wide Web Consortium) och IETF (Internet Engineering Task Force).

Syftet med rapporten är att uppmärksamma, diskutera och motivera de problem som finns idag på Internet. Uppsatsen argumenterar för WebSocket-lösningar vid realtidsuppdatering. Rapporten jämför tidigare lösningar och visar en annan möjlighet att lösa det på.

Rapporten visar hur WebSocket kan implementeras i en mobil eller webbapplikation och använder denna som en demonstration för de argument som vi för genom rapporten.

Abstract [en]

This report describes a bachelor thesis performed at the School of information and communication technology at the Royal Institute of Technology in Stockholm.

WebSocket is a new communication protocol which mainly is developed to increase performance in todays web communication. WebSocket is ment as a substitute to HTTP in areas which require low response time and ansynchronous updates. Today, WebSocket is supported by every modern web browser and has been standardized by W3C (World Wide Web Consortium) and IETF (Internet Engineering Task Force).

The purpose of this report is to highlight, discuss and explain the problems that exist today on the Internet. The report argues for WebSockets solutions in real-time updating. The report compares previous solutions and shows another possibility to solve this.

The report shows how WebSocket can be implemented in a mobile or web application and use this as a demonstration of the arguments that we perform in the report.
