Abstract: Nowadays ethernet is both LAN and WAN technology. This is possible because of switched ethernet. Switched ethernet is a modern counterpart of the historical ethernet. Switched ethernet replaces the shared medium of historical ethernet with a dedicated segment for each station. These segments connect to a switch, which can connect many of these single stations. This paper presents an integrated approach for real time communication in switched ethernet system by using RSVP (Resource reservation protocol) and EDF (earliest deadline first) algorithm. The node which wants to reserve the resources is scheduled in the switch according to EDF.

Keywords: EDF, Real Time Communication, RSVP, Switched Ethernet.
