According to one embodiment, a system and computer-readable storage medium for storage of software directed to the management of associations between network devices is described. The computer-readable storage medium comprising instructions which, when executed by at least one hardware processor on a network device, causes performance of operations, comprising: (1) determining a desired operating state for a client device under analysis, the client device being associated with a first network device of a plurality of network devices; (2) detecting if a triggering event has occurred based on a comparison of the desired operating state for the client device under analysis to an actual operating state for the client device under analysis; and (3) in response to detecting that the triggering event has occurred, causing the client device to wirelessly connect to a second network device of the plurality of network devices in lieu of the first network device.

System, apparatus and method for managing client devices within a wireless network

The present disclosure discloses a method and network device for automatic delivery traffic indication message (DTIM) interval control for better mobile power save performance. The disclosed network device determines one or more characteristics for at least one client device connected to an Access Point (AP). The network device then dynamically selects a DTIM interval for the AP based on the characteristics for the at least one client device, and configures the AP to transmit a DTIM beacon frame at a frequency based on the dynamically selected DTIM interval. Alternatively, the network device can determine one or more characteristics for a client device, and dynamically select a Virtual Access Point (VAP) for providing network access to the client device based on the characteristics for the client device and a DTIM interval configured for the VAP, and then cause the client device to connect to the VAP.

Automatic delivery traffic indication message interval control for better mobile power save performance

Infrastructure-based client management uses synthesized beacon reports to effect client association with APs in a wireless digital network. Beacon reports are synthesized by having a plurality of APs in the network collect client reports and send those reports to a report process on the network. The report process accumulates client reports from the plurality of APs and selects one or more candidate APs to support a client. Selection may be made on reported SNR, AP loading, channel loading, AP characteristics, or a combination. The report process may produce blacklists and optionally whitelists for use by APs to use in processing client probe and connection requests.

Infrastructure-assisted client management using synthesized beacon reports

A system with a device including a hardware processor is configured to perform operations: receiving, by the device, a message over a wired medium, wherein the message has a frame including (a) a MAC address as a source MAC address for the frame and (b) a second MAC address as a destination MAC address for the frame, extracting, by the device, the frame from the message received over the wired medium, and wirelessly transmitting, by the device, the frame without modifying the source MAC address and without modifying the destination MAC address.

Synthetic client

Provided are devices, computer-program products, and methods for calibration of a signal strength map for purposes of providing wireless positioning services through fingerprinting. Fingerprinting involves generating a map of the signal strengths in an area covered by a Wi-Fi network. In some implementations, a wireless probe request may be received. In these implementations, the wireless probe request may be associated with location information. In some implementations, the signal strength of the wireless probe request may be detected. In these implementations, the signal strength may indicate a signal characteristic between an origination and a destination for the wireless probe request. In some implementations, the wireless probe request may be responded to with a response message. In these implementations, the response message may include the signal strength of the wireless probe request. In these implementations, the response message and the location information may further facilitate generating an entry in a fingerprinting database.

Operations include determining that a subset of devices, from a plurality of devices, are executing a same application, located in a same geographical location, or correspond to a same user. Responsive to the determining operation, a group with the subset of devices is created and communication between the devices is supported.

Overlaying virtual broadcast domains on an underlying physical network

The present disclosure discloses a method and network device for adaptive management of wireless clients based on clients' radio behaviors and capabilities. Specifically, a disclosed network device can dynamically select a location tracking mechanism based on a probing characteristic of a client device. The disclosed network device can also dynamically selects a communication mechanism based on a power saving characteristics of a client device. Moreover, the disclosed network device can determine whether to select a new access point for a client device based on roaming characteristics of the client device. The adaptive management of client devices can be performed on a group of client devices with similar radio behaviors and/or capabilities on a per-radio rather than per-BSSID (basic service set identifier) basis.

Adaptive management of wireless clients based on clients radio behaviors and capabilities

The present disclosure discloses a method and network device for software-defined client device management. Specifically, a network device can cause a client device to switch association with a first access point to a second access point. The network device determines whether a number of times the client device has been caused to switch association with an access point exceeds a threshold value for the first period of time. If not, the network device causes the client device to switch to an association with a third access point. Also, the network device determines a configuration indicating when any access point with which a client device is associated may be modified. Based on the configuration, the network device determines whether an association of the client device should not be modified. Also, based on one or more attributes, the network device selectively causes the client device to switch an association.

Software defined wireless device management

According to one embodiment, a system and computer-readable storage medium for storage of software directed to the management of associations between network devices is described. The computer-readable storage medium comprising instructions which, when executed by at least one hardware processor on a network device, causes performance of operations, comprising: (1) determining a desired operating state for a client device under analysis, the client device being associated with a first network device of a plurality of network devices; (2) detecting it a triggering event has occurred based on a comparison of the desired operating state for the client device under analysis to an actual operating state for the client device under analysis; and (3) in response to detecting that the triggering event has occurred, causing the client device to wirelessly connect to a second network device of the plurality of network devices in lieu of the first network device.

Certain aspects and features of the present disclosure relate to providing access control using groups that can be dynamically controlled by group owners, such access control hereinafter referred to as group access control. Group access control can be used to control the transmission of packets on a network layer, or for other access control. A network administrator can provide users with permissions, such as using user roles. Users can then establish groups to share permissions with other users. A group is established by a group owner, who can modify the member list of that group and modify what permissions will be passed on to group members all without the involvement of a network administrator. Members of a group can include users, devices, and network resources. Additionally, data path entities (e.g. routers and access points) can facilitate delivery of packets between group members across multiple logical networks.

Access control through dynamic grouping

To facilitate management and configuration of VLAN memberships associated with applications or network protocols, a network device receives a packet from a wireless station which is a member of a virtual local area network (VLAN). The network device determines whether the packet is associated with a predefined application or network protocol. If so, the network device delivers the received packet to a dedicated VLAN which is accessible only to network devices associated with the predefined application or network protocol, regardless of destination address specified within the packet. If not, the network device delivers the received packet to an address or a group of addresses specified in a header of the received packet. In some embodiments, the VLAN is divided from a VLAN pool, and the dedicated VLAN corresponds to an address space that is outside the address space of the VLAN pool.
