Mass distribution with techniques as Multicast and peer-to-peer are becoming increasingly important in the Internet. Today the distribution of sound and video over Internet, so called streaming media, is static due to the unicast method. This results in a linear increase of distribution costs and therefore no conditions for commercial scalability. This thesis describes why Multicast may be the only scalable alternative for commercial mass distribution of streaming media over Internet. Mass distribution through peer-to-peer technology promises a lot but is fronting a couple of great challenges, for example asymmetric bandwidth, locality and legalization.

För att installera flera operativsystem samtidigt finns det olika verktyg avsedda för att underlätta denna process. Det finns både kommersiella- och gratisalternativ ute på marknaden. En av de ledande kommersiella replikeringsmjukvarorna är Symantec Ghost. I detta arbete jämförs Symantec Ghosts mot Free open-source ghost (FOG) för att mäta användbarheten med avseende på kritiska attribut. Kritiska attribut är baserade på utförandet av en fullständig replikeringsprocess samt hur en användare upplever hanteringen av mjukvaran.

The result of this master thesis report describes the advantages and the drawbacks that will arise when implementing an Ethernet based intercommunication system in military vehicles. The report presents a possible solution and describes how different sound applications will be implemented into the suggested solution. The report show that IP LAN in vehicles leads to more advantages than drawbacks. The main advantages are that all kind of media can share the same LAN and that there is a lot of knowledge of this technique in the civil area. The main drawback is about delay.
