Abstract
A method of transmitting delay sensitive information over Internet Protocol (IP) over Frame Relay including storing the information in an IP packet, storing the IP packet in a sub-frame, storing a special symbol representing that the frame is delay sensitive in the sub-frame, storing the sub-frame in a frame, storing a network layer protocol identification representing that the frame contains IP information in the frame, and transmitting the frame over a Frame Relay Network, distinguishing delay sensitive information from non-delay sensitive information by examining the special symbol. Additionally, in systems using the FRF.12 or similar fragmenting standard, the special symbol may be stored in the header of the fragment.
