Abstract
A method of transmitting isochronous and nonisochronous data through a computer network in which a plurality of stations have respective input and output ports that are serially coupled together to form a loop includes the steps of: transmitting data characters of a nonisochronous frame from a first station in the loop; passing the data characters from the first station through a second station in the loop but with a pair of control characters inserted between any two data characters indicating the beginning and end of an isochronous frame within the nonisochronous frame; passing the data characters and control characters from the second station through a third station on the loop but with another internally generated isochronous data character inserted between the control characters; temporarily stopping the transmitting step in the first station in response to the receipt of at least one of the control characters to pass the isochronous frame through the first station; and proceeding in the first station with the transmitting of the nonisochronous frame after passing the isochronous frame.
