|Presentation of the research project conducted on AI3 in AIT.|
The project aims to optimize the utilisation of the satellite links by adopting adaptive caching strategies with periodic prefetching.
Together with NAIST, we have developed a an adaptive cache which perform prefetching with adaptive strategies. By observing the traffic and delay on the satellite link, the cache servers decides whether to prefetch a WWW object. If the satellite link looks congested, periodic prefetching will pause.
The following subprojects are underway:
A study of the effect of weather condition on KU-Band transmission has been carried out by simulation models. It is planned that these results will be verified by actual experimentals data collected from all members of AI3.
In traditional circuit switched telephony network call are Analog and constantly use 64 Kbps of bandwidth. Internet Telephony is digital in nature where real-time voice communication occurs over a packet network using Internet Protocol. Internet Telephony represents a significant step towards the integration of voice and data in IP Network.
