Abstract:
1. An information processing apparatus which is a component of an information processing system in which real time data, for which transmission and reception assurance, within a predetermined period of time after every fixed period, is necessary, is communicated through an asynchronous network, the information processing apparatus comprising: a generator configured to generate time synchronizing information packets, the time synchronizing information packets setting transmission and reception schedules of the real time data and having a first region containing a sequence number which varies after every period of time corresponding to the fixed period, and at least one of the time synchronizing information packets having a second region containing data corresponding to a configuration state of the asynchronous network, without all of the time synchronizing information packets having the second region containing data corresponding to the configuration state of the asynchronous network; and a transmission controller configured to control the time synchronizing information packets generated by said generator such that one time synchronizing information packet is transmitted to said asynchronous network at each transmission timing after the fixed period, the time synchronizing information packets being of a type distinct from other packets of the real time data being transmitted to said asynchronous network, and at least two of the time synchronizing information packets having different packet structures.
