  • Publication number: 20180063766
    Abstract: A technique for implementing AP-local dynamic switching involves Layer 2 switching. This may be accomplished by providing data associated with wireless stations to an AP sufficient to enable the AP to determine whether traffic from a particular wireless station should be locally switched. Alternatively, the wireless station may be able to determine whether to locally switch traffic based upon the traffic itself. For example, it may be desirable to AP-locally switch voice traffic to avoid latency, which is particularly detrimental to voice transmissions such as voice-over-IP. Traffic that is not to be switched locally is Layer 2 tunneled upstream.

  • Publication number: 20160088551
    Abstract: A technique for implementing an untethered access point (UAP) mesh involves enabling AP-local switching at one or more UAPs of the mesh. A system constructed according to the technique may include a wireless switch; an access point (AP) wire-coupled to the wireless switch; and a UAP mesh, wirelessly coupled to the AP, including a UAP with an AP-local switching engine embodied in a computer-readable medium. Another system constructed according to the technique may include an untethered access point (UAP), including: a radio; a backhaul service set identifier (SSID) stored in a computer-readable medium; an anchor access point (AAP) selection engine embodied in a computer-readable medium. In operation, the AAP selection engine may use the radio to attempt to associate with the AAP if a beaconed backhaul SSID matches the stored backhaul SSID.

  • Publication number: 20160021528
    Abstract: A technique for facilitating the management of a wireless database related to station records and radio-frequency (RF) information by reducing unnecessary sharing of the data among wireless switches, thus enhancing efficiency in a wireless network. A system constructed according to the technique includes a collection of wireless switches with each switch having associated access points (AP), an AP database distributed throughout the collection of wireless switches, and at least one station radio frequency (RF) database. The AP database includes data associated with ownership of the AP's by the switches, and the station RF database includes wireless station information and RF information. AP radio adjacency is determined by whether an AP owned by a specific switch can detect the other AP owned by another switch. The station and RF information database is shared only within the subset of switches that have AP radio adjacency.

  • Patent number: 8964747
    Abstract: This specification describes a system that can offer, among other advantages, dynamically allowing or rejecting non-DHCP packets entering a switch. In addition, a FDB is commonly used by a bridge or switch to store an incoming packet's source MAC address and its port number, then later on if the destination MAC address of another incoming packet matching any entry in FDB will be forwarded to its associated port. Using the techniques described herein, not only this will be completely transparent to user, the techniques can also result in an increase in switch performance by blocking unwanted traffic at an earlier stage of forwarding process and freeing up other processing units at a later stage, like switch fabric or packet processing stages.

  • Patent number: 8902904
    Abstract: Systems and methods for network assignment based on priority are described in this application. In one aspect, a technique for network assignment based on priority relates to establishing a connection between a client and a virtual local area network (VLAN), based on an explicit or implicit network priority preference of the client. In an embodiment, multiple VLANs can be combined into one network bundle, the network bundle being a unit network for priority specification. In addition, multiple network bundles may be available for network assignment on a particular network controller (e.g., network switch). For example, the preferred network of a client may be comprised of several individual VLANs. Thus, the client can be assigned to any of the constituent VLANs included in the preferred network bundle.

  • Patent number: 8804732
    Abstract: In some embodiments, an apparatus includes a wireless access point controller configured to receive information associated with a topology of a network including information associated with which access switch from a set of access switches each virtual local area network (VLAN) from a set of VLANs is associated. The wireless access point controller is configured to associate each VLAN from the set of VLANs with a unique tunnel identifier from a set of tunnel identifiers. The wireless access point controller is configured to provide each wireless access point from a set of wireless access points control information including the set of tunnel identifiers such that a wireless access point from the set of wireless access points can send a data packet received from a wireless device to an access switch from the set of access switches associated with a destination VLAN from the set of VLANs using the tunnel identifier associated with the destination VLAN.

  • Patent number: 8670383
    Abstract: A technique for improved throughput at an access point (AP) involves when frames are received for transmission by the AP, queuing the frames for a particular station. A system constructed according to the technique may include an aggregation and queuing layer. Station queues may be processed by the aggregation and queuing layer before being given to radio hardware for transmission. In an illustrative embodiment, when frames are received by the aggregation and queuing layer, the packet will be assigned a target delivery time (TDT) and an acceptable delivery time (ADT). The TDT is the “ideal” time to transmit a frame, based on its jitter and throughput requirements. Frames are mapped on to a time axis for transmission by TDT. In an illustrative embodiment, each frame is mapped by priority, so that there are separate maps for voice, video, best effort, and background frames. There will be gaps between frames for transmission that can be used for aggregation.

  • Patent number: 8638762
    Abstract: A technique for maintaining network integrity is disclosed. A system according to the technique may include a wired network, a switch, and a wireless access point. The switch can be coupled to the wired network and the wireless access point can be coupled to the switch. The system may further include a forwarding database that stores a mac address for a plurality of devices seen by the switch on the wired network. A method according to the technique may involve detecting identifying information of a device by a wireless access point. The identifying information can be compared with the mac addresses in a forwarding database. If the device is unknown, the unknown device can be classified as rogue and countermeasures can be taken against the rogue device.

  • Patent number: 8605637
    Abstract: A technique for controlling the amount of power consumed by access points (APs) of a wireless network involves implementing throttleable APs (TAPs). It would be desirable for the TAPs to be in a relatively low power mode during periods of low activity, and switch to a high power mode in response to increased wireless activity. To that end, a throttling engine can be implemented to throttle TAPs up in power in response to increases in wireless activity, and throttle TAPs down in power in response to decreases in wireless activity.
