Abstract
The switched Ethernet offers many attractive features for real-time communications such as traffic isolation, providing large bandwidth, and full-duplex links, but the real-time features may be affected due to the collisions on an output port. This paper analyzes the schedulability condition for real-time periodic messages on a switched Ethernet where all nodes operate in a synchronized mode. This paper also proposes a EDF (Earliest Deadline First)-based scheduling algorithm to support the real-time features of the periodic traffic over switched Ethernet without any change in the principles of switched Ethernet. The proposed algorithm allows dynamic addition of new periodic messages during system running, which gives more flexibility to designing the real-time systems.
