Publication number: 20170332423Abstract: Establishing peer-to-peer tunnels between clients in a mobility domain. In normal operation, clients attached to a network having access nodes connected to a central controller transfer all traffic through the central controller. This traffic is passed using tunnels between the access node and the central controller. Tunnels may be encrypted, and GRE tunnels may be used. A mobility manager operating in the controller tracks access nodes connected to the controller, and clients connected to those access nodes. When the mobility controller recognizes traffic passing between clients in its mobility domain that is eligible for peer-to-peer forwarding, it instructs the access nodes supporting the clients to establish a peer-to-peer tunnel between the nodes, and direct the client traffic through this peer-to-peer tunnel. The peer-to-peer tunnel may be session based, or may be aged.Type: ApplicationFiled: March 20, 2015Publication date: November 16, 2017Inventors: Pradeep J. Iyer, Keerti G. Melkote

Patent number: 9432848Abstract: Band steering for multi-band wireless clients. According to one embodiment of the invention, a method of operations comprises receiving, at a network device, a request from a wireless client device on a first wireless communication band. Thereafter, the network device identifies a unique address identifier associated with the wireless client device based on the received request and stores the unique address identifier in response to determining that the wireless client device is capable of communicating on the first wireless communication band.Type: GrantFiled: January 31, 2012Date of Patent: August 30, 2016Assignee: Aruba Networks, Inc.Inventors: Pradeep J.

Patent number: 9049045Abstract: One of the embodiments is directed to establishing peer-to-peer tunnels between clients in a mobility domain. Normally, clients attached to a network having access nodes connected to a central controller transfer all traffic through the central controller via tunnels between the access node and the central controller. A mobility manager operating in the controller tracks access nodes connected to the controller, and clients connected to those access nodes. When the mobility controller recognizes traffic passing between clients in its mobility domain that is eligible for peer-to-peer forwarding, it instructs the access nodes supporting the clients to establish a peer-to-peer tunnel between the nodes, and direct the client traffic through this peer-to-peer tunnel. The peer-to-peer tunnel may be session based, or may be aged. Eligibility of traffic for peer-to-peer tunnels may be controlled by rules, such as limiting peer-to-peer tunnels by source or destination, by port or protocol, and the like.Type: GrantFiled: April 24, 2009Date of Patent: June 2, 2015Assignee: ARUBA NETWORKS, INC.Inventors: Pradeep J. Iyer, Keerti G. Melkote

Patent number: 8699418Abstract: Band steering for multi-band wireless clients. In a wireless digital network having at least one central controller and a plurality of access nodes connected to the central controller, and wherein some of the access nodes support a preferred wireless band and at least one non-preferred wireless band, the central controller identifies wireless client devices capable of multi-band operation, and encourages them to connect to the preferred wireless band. Client devices may be identified as multi-band capable by tracking probe requests. The central controller keeps a list of multi-band capable clients, for example in a database. This information is provided to other central controllers, and to access nodes attached to the central controller. Multi-band capable clients are encouraged to connect on the preferred wireless band for example by having the access nodes not respond to probe requests on the non-preferred wireless bands.Type: GrantFiled: June 8, 2011Date of Patent: April 15, 2014Assignee: Aruba Networks, Inc.Inventors: Pradeep J.

Patent number: 7525943Abstract: In general, one embodiment of the invention relates to a method of operation where the type of an incoming Media Access Control (MAC) frame is initially determined. Based on such determination, the MAC frame is processed locally at an access point if the MAC frame is one of a first group of MAC frames. Otherwise, the MAC frame is processed remotely at a switch communicatively coupled to the access point.Type: GrantFiled: April 4, 2005Date of Patent: April 28, 2009Assignee: Aruba Networks, Inc.Inventors: Pradeep J.

Patent number: 7414995Abstract: In general, one embodiment of the invention is a radio access point (RAP) system adapted to a wired network. The RAP system comprises a radio access point and a switch coupled together by an interconnect. The radio access point includes components to digitally sample a detected, wireless analog signal thereby producing digital data. The digital data is placed into a frame for transmission over the interconnect. The switch includes a radio access point (RAP) component that recovers the digital data from the frame transmitted over the interconnect. The RAP component processes the digital data to recover media access control (MAC) frames containing data for subsequent transmission over the wired network.Type: GrantFiled: September 9, 2002Date of Patent: August 19, 2008Assignee: Aruba Networks, Inc.Inventors: Keerti G. Melkote, Pankaj S. Manglik, Joel F. Adam
