The hub for the net inside the segmentation hypothetical limits which possess joint ownership medium access

摘要

(57) Abstract Perhaps the hub of the net inside the segmentation hypothetical limits which possess joint ownership medium access (10) in order sending and receiving to do digital data message the internal port of one or more (12) it possesses at least inside that hub, and in order sending and receiving to do the digital data message outside that hub the external port of one or more (18) it possesses at least. As for that hub, inside and the net inside the hypothetical limits of the external port (VLAN) memory in order to remember appointment (42), at least the internal port and correspondence of one or more acquiring VLAN appointment, expedient in order to remember that kind of VLAN appointment inside memory (60), and the empty the message which was transmitted correspondence expedient in order to attach (64) with furthermore it includes either of the ports to which VLAN appointment can allot the VLAN appointment which is remembered. Additional, as for that hub with that hub, or the message which is received inside the range correspondence expedient in order to identify the VLAN appointment which is attached (66) with, transmitting only the message which is received inside the hub to the port inside in each case, the VLAN appointment which to that port matches allotment memory VLAN appointment those messages correspondence expedient in order to attach (68) with it includes both. As for that hub, the port and correspondence the medium access control which is attached (MAC) address is remembered, when it understands via that port only and destination address of the message it is that reachable perhaps also the ability to send message to the port possesses.
