A METHOD FOR EXTENDING VLAN BRIDGING SEMANTICS AND AN APPARTUS FOR SENDING FRAMES IN BRIDGED, CRYPTOGRAPHIC VLANS

摘要

The invention comprises there extention of the XXXX VLAN bridge moded. The first ectention is the cryXXX graphic separation of VLANs over XXX links. A LAN segment type reffered XXX as an encapXXX LAN segment is introduced. An. frames or sucha segment are encapsulated according to an encryption and XXX scheme. The second extention is the: division of a trunk port into inbound and outbound ports. The third extention is a protocol that automatically XXX for each outbound port in a bridge VLAN. a set of LAN segment types for the port that minimizes the number of transfer between encapsulated and unencapsulated segments required to transport a frame in the bridge VLAN.
