Abstract [en]

The Internet is becoming increasingly fragmented, leading to a more heterogeneous end-user experience depending on the user's network location (i.e., point of attachment to the network). This is a consequence of several ongoing changes of the Internet. Different regions of the world are in different phases of their rollout of IPv6, making intercommunication increasingly challenging. Copyright legislation has caught up with ICT technology, but differences in licensing agreements may very from nation to nation which often hinders content being accessed beyond borders. Finally, several high-profile government attempts have been made to enforce stringent censorship of data.

Therefore, we believe that a demand exists for simple consumer-oriented technologies for proxying and tunneling data between separate regions of the Internet. Furthermore, we believe that this demand will increase dramatically during the coming years. A key success factor for this next generation of proxies will be the ability to handle multicast IPv6 packets, as these packets represent the most probable distribution method for IPTV in the future.

This thesis examines the challenges presented by IPv6 multicast-routing in the context of constructing a proxy. It also presents a best-practice solution to the problem of designing, implementing, and utilizing such a proxy. The thesis also contains a review of current IPv6 multicast routing technology. Several implementations are benchmarked against each other, with the goal of building a prototype for a consumer-oriented IPv6 multicast proxy. The prototype is presented and was tested. These tests demonstrate the functionality of the prototype proxy and reveal areas where the prototype could be improved. Finally a possible capitalization strategy is suggested.

Abstract [sv]

Internet utvecklas mot att bli mer fragmenterat. Detta leder till en heterogen användarupplevelse beroende på uppkopplingspunkt. Utvecklingen är en konsekvens av flera pågående trender. Världens olika regioner ligger i ofas i utbyggnaden av IPv6 vilket medför nya tekniska utmaningar. Samtidigt har upphovsrättslagstiftningen hunnit ikapp teknikutvecklingen, så att länder med olika licensieringsmodeller inte kan dela innehåll. Slutligen försöker flera länder aktivt censurera datatrafik.

Som konsekvens av detta ökar behovet för enkla konsumentorienterade metoder för att knyta ihop olika delar av Internet, så att åtkomst till data garanteras oavsett uppkopplingspunkt. Därmed förutspår vi att efterfrågan på produkter baserade på sofistikerad tunnelteknik kommer öka under de kommande åren.

Denna rapport undersöker de utmaningar IPv6 multicast routing medför i samband med byggandet av en IPv6 multicast proxy. Rapporten presenterar en grundlig teoretisk genomgång av tekniken bakom IPv6 multicast routing. Vidare föreslås ett optimalt tillvägagångssätt för att designa, bygga och använda en sådan proxy. Flera existerande tekniker för multicast forwarding utvärderas och jämförs. Utifrån utvärderingen byggdes tre implementeringar av en IPv6 multicast proxy. Därefter analyseras dessa, tillsammans med förslag för fortsatta studier. Slutligen presenteras en möjlig kapitaliseringsstrategi för tekniken.
