Patent number: 8514827Abstract: A technique for wireless network monitoring involves scanning channels using clients instead of access points. An example of a method according to the technique may include, for example, receiving from a wireless access point a command to perform a channel scanning function, listening on a channel associated with the channel scanning function, and sending RF data found on the channel to the wireless access point. Another example of a method according to the technique may include, for example, scanning a first channel, switching from the first channel to a second channel, sending data on the second channel to an access point, switching from the second channel to the first channel, and resuming scanning on the first channel. A system according to the technique may include one or more scanning clients, proxy clients, multi-channel clients, or other clients that are capable of scanning channels in lieu of an access point.Type: GrantFiled: February 14, 2012Date of Patent: August 20, 2013Assignee: Trapeze Networks, Inc.Inventors: Sudheer Poorna Chandra Matta, Manish Tiwari

Patent number: 8474023Abstract: In wireless networking, such as per the IEEE 802.11 standard, a technique automatically republishes an authentication credential to a global credential repository. A station can have a first credential, as is created when the station connects to a first access node of a wireless network. Upon trying and failing to connect to a second access node of the wireless network, the station can have a second credential created and published to the global credential repository. In some situations, the station then roams back to the first access node using the first credential. Efficiently, when the station uses the first credential at the first access node, the first credential can be automatically republished as a global credential. The automatic republishing of the first credential can ensure that the station is able to access the wireless network via various access nodes when roaming.Type: GrantFiled: May 30, 2008Date of Patent: June 25, 2013Assignee: Juniper Networks, Inc.Inventors: Vineet Verma, Sudheer Poorna Chandra Matta

Patent number: 8457031Abstract: A technique for reliable multicast involves identifying a client as an acknowledger of a wireless multicast packet, and having the acknowledger acknowledge receipt of the multicast packet. An example of a method according to the technique may include receiving a multicast packet, selecting a client associated with a destination of the multicast packet, identifying the client in the multicast packet, forwarding the multicast packet to wireless, and retrying forwarding the multicast packet with the client identified in the multicast packet if no acknowledgement is received from the client. An example of a system according to the technique may include a means for identifying a client, a means for putting the client mac in the header of a multicast packet, a means for sending the multicast packet with the client mac to a wireless multicast destination, and a means for receiving acknowledgement from the client associated with the client mac.Type: GrantFiled: January 11, 2006Date of Patent: June 4, 2013Assignee: Trapeze Networks, Inc.Inventor: Sudheer Poorna Chandra Matta

Patent number: 8320949Abstract: A technique for wireless load balancing involves providing a wireless infrastructure that creates a target band option and helps push clients toward that band. An example of a method according to the technique involves, by way of example but not limitation, responding only to probe requests on a first band when a client is detected on the first band and a second band. For example, using the techniques described herein, a platform that is both 802.11a and 802.11b/g compliant may attempt to connect preferentially to the 802.11b/g band of a wireless network, and be migrated toward the 802.11a band instead.Type: GrantFiled: October 13, 2011Date of Patent: November 27, 2012Assignee: Juniper Networks, Inc.Inventor: Sudheer Poorna Chandra Matta
