  • Publication number: 20140269499
    Abstract: In an example embodiment, an access point or wireless local area network controller programs an opaque cookie into a wireless client. The cookie carries association detail and current traffic information of the client. When the client roams to a new access point, the client presents the cookie to the new access point.

  • Publication number: 20140171069
    Abstract: In an example embodiment, a neighbor radio/access point (AP) list is obtained. The neighbor AP list is optimized for a client that is associated with a current access point. The list may be optimized based on any one or combination of techniques, including but not limited to roaming patterns of previous clients that were associated with the current access point, radio frequency metrics, bandwidth requirements for the client, and/or any other suitable criteria. In particular embodiments, requests from the client to associate with an access point that is not on the optimized neighbor AP list may be denied.

  • Patent number: 8739045
    Abstract: An example method is provided and includes establishing a communication session involving a first endpoint and a second endpoint associated with a meeting in a network environment. The first endpoint is associated with a first identifier and the second endpoint being associated with a second identifier. The method also includes designating the first endpoint as a speaking leader for a segment of the communication session, the second endpoint operates in a listening mode while the first endpoint operates as the speaking leader. The method also includes rendering a symbol indicative of the first endpoint being the speaking leader for the segment. The symbol and the first identifier are associated on a user interface.

  • Patent number: 8611270
    Abstract: In one embodiment, a system that employs IGMP (Internet Group Management Protocol) snooping and client tracking to forward an IP multicast flow between a distribution (e.g., wired or backbone) network and a wireless network without the need to configure a VLAN on either infrastructure. A single IP multicast flow is forwarded natively on the distribution network (e.g., from an IP Multicast enabled router) to an AP, and the AP replicates and forwards the multicast flow to a plurality of domains on the wireless network.

  • Publication number: 20130293665
    Abstract: In an example embodiment, there is disclosed an apparatus comprising an interface and conferencing logic coupled with the interface. The conferencing logic is operable to receive via the interface data representative of a conference call for a meeting, the data representative of the meeting comprises data representative of a meeting time and data representative of a meeting participant. The conferencing logic is operable to receive via the interface data representative of a callback number and data representative of a callback time from the meeting participant. The conferencing logic is operable to initiate communications with the meeting participant at the callback time at the callback number. The conferencing logic is operable to couple the meeting participant with the conference call upon establishing communications.

  • Publication number: 20130201863
    Abstract: Devices, methods and instructions encoded on computer readable media are provided herein for estimation of the available bandwidth in a frequency channel shared by a first access point and at least one neighboring access point. In one example, an impact value that represents the impact of traffic associated with the neighboring access point on the first access point is calculated. Based on the impact value, a first utilization metric associated with the first access point is generated. The first utilization metric represents the bandwidth available on the frequency channel in the presence of the traffic associated with the neighboring access point.

  • Patent number: 8411629
    Abstract: Techniques are provided herein for computing a video admission control metric used to determine whether to admit a new video stream to a wireless network. The video admission control metric is computed using several measurable parameters of the wireless network. The dynamic nature of this process takes into account many real-time factors that affect admission control, such as traffic load, channel conditions, and overlapping basic service set (BSS) interference.

  • Publication number: 20130028163
    Abstract: Techniques are provided for a foreign controller to receive a handoff message including information for a multicast group that is used to forward network control information originating from an Internet Protocol version 6 (IPv6) network router by a home wireless controller to one or more foreign wireless controllers for mobile client devices that were first associated with the home controller. The foreign controller joins a multicast group based on the information contained in the handoff message and establishes a communication path with a mobile client device. The foreign controller extracts network control information addressed to the mobile client device received from the home wireless controller via a multicast stream associated with the multicast group, and forwards the network control information to the mobile client device via the communication path.
