Patent ID: 7889647

Claim:
A switching apparatus comprising: a determination device for determining whether or not received packets are real-time packets; a detection device for detecting real-time packets that do not vary from a transmission cycle of the real-time packets by a source apparatus and that are keeping the transmission cycle of the real-time packets by the source apparatus, among the real-time packets determined by the determination device; a measurement device for measuring a reception cycle between the real-time packets that do not vary based on a reception time of a real-time packet that does not vary and a next reception time of a next real-time packet that does not vary; an expecting device for expecting reception timings that subsequent real-time packets that do not vary are to be received based on the reception cycle measured by the measurement device; an inhibiting device for inhibiting a transmission of non-real-time packets, so as not to transmit the non-real-time packets at the reception timings expected by the expecting device; and a switching device for switching a series of real-time packets that do not vary after measurement by the measurement device at the transmission cycle that is keeping the transmission cycle of the real-time packets by the source apparatus.
