ABSTRACT:
A zero-delay queuing method and system. The zero-delay queuing method includes the steps of: when a packet corresponds to a class set to perform zero-delay queuing, transferring the packet to a zero-delay queue; when a size of the packet does not exceed a CR value set for the class, transferring the packet to a strict priority transfer queue; and forwarding the packet existing in the strict priority transfer queue prior to packets existing in general data transfer queues. According to the zero-delay queuing method and system, it is possible to forward specific traffic requiring real-time transfer without delay, and furthermore, it is possible to serve packets corresponding to a zero-delay queue while ensuring a Peak Rate (PR) value as well as a Committed Rate (CR) value.
