Patent number: 9730070Abstract: The invention instantiates a Personal VLAN bridge, using IEEE Std. 802.11 elements. The result is a bridge, referred to as a public access point, that is better suited for implementing public wireless data networks than the IEEE Std. 802.11 architecture. The invention also provides a location-update protocol for updating the forwarding tables of bridges that connect public access points together. The invention further provides a method for more controlled bridging, which is referred to as fine bridging.Type: GrantFiled: May 20, 2014Date of Patent: August 8, 2017Assignee: Microsoft Technology Licensing, LLCInventor: Dennis Michael Volpano

Patent number: 8966611Abstract: A mechanism for segregating traffic amongst STAs that are associated with a bridge, referred to herein as the personal virtual bridged local area network (personal VLAN), is based upon the use of a VLAN to segregate traffic. The IEEE 802.1Q-1998 (virtual bridged LANs) protocol provides a mechanism that is extended by the invention to partition a LAN segment logically into multiple VLANs. One embodiment of the invention extends the standard VLAN bridge model to provide a mechanism that is suitable for use within an AP. In a preferred embodiment, the Personal VLAN bridge extends the standard VLAN bridge in at least any of the following ways: VLAN discovery in which a personal VLAN bridge provides a protocol for VLAN discovery; VLAN extension in which a Personal VLAN allows a station to create a new port that serves a new VLAN, or to join an existing VLAN via an authentication protocol.Type: GrantFiled: August 20, 2012Date of Patent: February 24, 2015Assignee: Mircosoft Technology Licensing, LLCInventor: Dennis Michael Volpano

Publication number: 20130024692Abstract: A mechanism for segregating traffic amongst STAs that are associated with a bridge, referred to herein as the personal virtual bridged local area network (personal VLAN), is based upon the use of a VLAN to segregate traffic. The IEEE 802.1Q-1998 (virtual bridged LANs) protocol provides a mechanism that is extended by the invention to partition a LAN segment logically into multiple VLANs. In the preferred embodiment, a VLAN bridge forwards unicast and group frames only to those ports that serve the VLAN to which the frames belong. One embodiment of the invention extends the standard VLAN bridge model to provide a mechanism that is suitable for use within an AP.Type: ApplicationFiled: August 20, 2012Publication date: January 24, 2013Applicant: MICROSOFT CORPORATIONInventor: DENNIS MICHAEL VOLPANO

Patent number: 8347377Abstract: The invention comprises three extensions of the IEEE 802.1Q VLAN bridge model. The first extension is the cryptographic separation of VLANs over trunk links. A LAN segment type referred to as an encapsulated LAN segment is introduced. All frames on such a segment are encapsulated according to an encryption and authentication code scheme. The second extension is the division of a trunk port into inbound and outbound ports. The third extension is a protocol that automatically infers for each outbound port in a bridged VLAN, a set of LAN segment types for the port that minimizes the number of transfers between encapsulated and unencapsulated segments required to transport a frame in the bridged VLAN.Type: GrantFiled: September 13, 2010Date of Patent: January 1, 2013Assignee: Microsoft CorporationInventors: Dennis Michael Volpano, Xinhua J.
