Data transmission device
First Claim
1. A data transmission device connected in plurality via transmission paths for forming a plurality of topologies, comprising:
- a network identification information processing section for creating network identification information for each of said topology;
a receive section for receiving and extracting said network identification information from an adjacent device; and
a topology change detection processing section, including a comparison section for comparing said extracted network identification information with the network identification information of a local device generated by said network identification information processing section, and a topology information construction section for reconstructing only said topology of which change has been detected if said comparison section detects the change.

Abstract
A multiple spanning tree protocol network which does not influence at all MSTI to which VLAN-ID is not added/deleted and does not reconstruct the topology of this MSTI. In the multiple spanning tree protocol network, a plurality of devices are connected via transmission paths, forming a plurality of topologies, and each of the plurality of devices comprises a network identification information processing section for creating network identification information for each topology, a receive section for receiving and extracting the network identification information from an adjacent device, and a topology change detection processing section, comprising a comparison section for comparing the extracted network identification information with the network identification information of the local device generated by the network identification information processing section and detecting the change, and a topology information construction section for reconstructing only the topology of which change has been detected if the comparison section detects the change.
