Abstract
A method of transmitting isochronous and nonisochronous data in a computer network in which multiple stations have respective input and output ports that are serially coupled together to form a loop includes the steps of: transmitting nonisochronous data from one station of the network and passing it through the remaining stations; periodically inserting into the nonisochronous data a lead control character followed by a trail control character and circulating the control characters twice around the network; increasing, in any station of the network that has isochronous data to send, the distance between the lead and trail control characters and sending isochronous data immediately before the trail control character as it passes through the station; subsequently decreasing the distance between the lead and trail control characters in each station of the network that performs the sending step by removing, from immediately behind the first lead control character to enter the station after the sending step begins, the same number of characters that it sent before the trail control character.
