Abstract
A packet passed to an IEEE 1394 bus is received by a packet receiver (421) and stored into a packet buffer (422). Source and destination IDs from the packet buffer (422) are supplied to a comparison/calculation circuit (428) which are also supplied with ID values from a subnetwork routing register (425), bus routing register (426) and node IDs register (427). The comparison/calculation circuit (428) will judge, based on such signals, whether the packet is to be transferred, and when it decides that the packet is to be transferred, will activate the output signal and open a gate (423) to transmit the packet to an inner fabric (401).
Claims10
A network system comprising:
- a plurality of subnetworks each formed from at least one bus in which at least one node is connected via a common transmission control signal channel;
- a first bridge holding first flags for the buses in the plurality of subnetworks and second flags representing a number of the plurality of subnetworks;
- and
- a second bridge connecting the plurality of subnetworks and holding the second flags for the number of subnetworks,
- wherein the second bridge includes comparing means for comparing a destination ID of the input packet data with the first and second flags, and acquisition means for acquiring the input packet data into the second bridge corresponding to a result of the comparison from the comparing means.
