    Description

    Background



    [0001] Networks can include a plurality of access points that are controlled by a controller. The controller can be a centralized controller for the plurality of access points. The controller can be utilized to manage, configure, monitor, and/or troubleshoot the plurality of access points within a network. The controller can be utilized to encrypt and/or decrypt data packets received from the plurality of access points. The controller can be utilized to configure the plurality of access points and/or change a configuration of the plurality of access points.

    [0002] US 2013/70163515 A1 discloses a system and method for providing multiple service set identifiers (SSIDs) in a single access point. The system within the single access point comprises a network management module, a virtual access point creation module and a data traffic handling module. The virtual access point creation module creates multiple virtual access points each represented by a unique SSID. The network management module provides at least one tunnel to accommodate the multiple virtual access points. The data traffic handling module receives and redirects data from the multiple virtual access points to and from the at least one tunnel.

    [0003] US 2002/0022483 A1 discloses a system and method for providing access to multiple wireless service providers (WSPs) on a shared network infrastructure. The system includes a plurality of access points (APs) coupled to a network which may be distributed in airports, mass-transit stations, businesses, etc. The network may couple to a wide area network, such as the Internet. Each AP may include a plurality of virtual APs (VAPs), each corresponding to a WSP. A portable computing device (PCD) of a user stores identification information indicating a WSP of a plurality of possible WSPs, and which may include an access level of the user. Each AP "listens for" or detects identification information associated with numerous WSPs. When the AP receives the identification information from the PCD, it determines the VAP/WSP for the PCD using the identification information. Network access is then provided to the PCD through the determined WSP at the determined access level.

    [0004] US 2014/0126466 A1 relates to virtual wireless networking. An access controller is coupled to a plurality of physical access points. The access controller is operable to create a plurality of virtual access controllers that are each coupled to the plurality of physical access points. The access controller then creates a different virtual access point for each of the plurality of virtual access controllers, and associates the virtual access point of each virtual access controller with each of the plurality of physical access points coupled to that virtual access controller. The access controller then provides a plurality of different wireless sub-networks through each of the plurality of physical access points, with each virtual access controller providing one of the different wireless sub-networks using the virtual access point associated with each of the plurality of physical access points coupled to that virtual access controller.

    Detailed Description



    [0007] Multi-connection access point systems can enable a plurality of different controllers to control functions of a single access point within a network. As used herein, a controller (e.g., network controller) can be a network device that can be utilized to manage, configure, monitor, and/or troubleshoot access points within a network (e.g., wireless network, local area network (LAN), wide area network (WAN), internet, etc.). As used herein, 'access point' (AP) generally refers to receiving points for any known or convenient wireless access technology which may later become known. Specifically, the term AP is not intended to be limited to IEEE 802.11-based APs. APs generally function as an electronic device that is adapted to allow wireless devices to connect to a wired network via various communications standards. The network can include a plurality of access points to enable computing devices to exchange data. In some examples, a first computing device can exchange data packets with a second computing device via a plurality of access points.

    [0008] The multi-connection access point systems can utilize a plurality of controllers to manage access points of the network. In some examples, the plurality of controllers can manage the same access points of the network. For example, the plurality of access points can include a plurality of ESSIDs that correspond to the plurality of controllers. In this example, an access point from the plurality of access points can direct data packets to a particular controller of the plurality of controllers based on an ESSID of the data packets received by the plurality of access points. For example, a first controller can have a first ESSID and a second controller can have a second ESSID. In this example, an access point can include the first ESSID and the second ESSID. In this example, the access point can direct data packets with the first ESSID to the first controller and direct packets with the second ESSID to the second controller. In some examples, the first controller and the second controller can be separated by an air gap. As used herein, an air gap is a network security measure to physically isolate a first network from a second network such that communication does not exist between the first network and the second network.

    [0009] The multi-connection access point system can enable a plurality of access points to be managed by a plurality of different controllers simultaneously. In some examples, the multi-connection access point system can be utilized separate a first type of data to a first controller and a second type of data to a second controller based on an ESSID of the data. In some examples, the first controller can be utilized by a first entity and the second controller can be utilized by a second entity. In these examples, the first controller and the second controller can be separated by an air gap to secure data of the first entity from the second entity and vice versa. In other examples, the first controller can be utilized to encrypt or decrypt data packets with a first security level and the second controller can be utilized to encrypt or decrypt data packets with a second security level.

    [0010] Figure 1 illustrates an example environment 100 for multi-connection access point, consistent with the present disclosure. The environment 100 can represent a network with a plurality of access points 102-1, 102-2, 102-3 in communication with a plurality of controllers 106-1, 106-2, 106-3. In some examples, the plurality of access points 102-1, 102-2, 102-3 can be coupled to a number of devices (e.g., user devices, mobile devices, etc.) to transmit data packets from the number of devices to one or more of the plurality of controllers 106-1, 106-2, 106-3.

    [0011] In some examples, each of the plurality of access points 102-1, 102-2, 102-3 can be coupled to each of the plurality of controllers 106-1, 106-2, 106-3. In these examples, the plurality of access points 102-1, 102-2, 102-3 can include a corresponding ESSID to each of the plurality of controllers 106-1, 106-2, 106-3. For example, the access point 102-1 can be coupled and/or managed by controller 106-1 via pathway 112-1 with a corresponding ESSID. In this example, the access point 102-1 can also be coupled and/or managed by controller 106-2 via pathway 112-2 with a corresponding second ESSID. In this example, the access point 102-1 can also be coupled and/or managed by controller 106-3 via pathway 112-3 with a corresponding third ESSID.

    [0012] Each of the plurality of controllers 106-1, 106-2, 106-3 can be within a corresponding zone of a plurality of zones 104-1, 104-2, 104-3. In some examples, each of the plurality of zones 104-1, 104-2, 104-3 can be separated by air gaps 108-1, 108-2. For example, zone 104-1 and zone 104-2 can be separated by air gap 108-1. Separating each of the plurality of zones 104-1, 104-2, 104-3 by air gaps 108-1, 108-2 can prevent communication between each of the plurality of controllers 106-1, 106-2, 106-3. In addition, separating each of the plurality of zones 104-1, 104-2, 104-3 by air gaps 108-1, 108-2 can allow a first controller of the plurality controllers 106-1, 106-2, 106-3 to manage the plurality of access points 102-1, 102-2, 102-3 without affecting a second controller of the plurality of controllers 106-1, 106-2, 106-3 from separately managing the plurality of access points 102-1, 102-2, 102-3.

    [0013] In some examples, each of the plurality of controllers 106-1, 106-2, 106-3 can utilize a particular communication protocol. For example, the controller 106-1 can utilize a first protocol and controller 106-2 can utilize a second protocol. In some examples, the first protocol can be different than the second protocol.

    [0014] In some examples, one of the plurality of controllers 106-1, 106-2, 106-3 in a first zone of the plurality of zones 104-1, 104-2, 104-3 can alter or change a number of settings for the plurality of access points 102-1, 102-2, 102-3 without altering settings of a second zone of the plurality of zones 104-1, 104-2, 104-3. For example, controller 106-2 within zone 104-2 can alter settings of the access points 102-1, 102-2, 102-3 that correspond to zone 104-2. In this example, the altered settings corresponding to the zone 104-2 may not affect settings of zone 104-1 or zone 104-3. That is, the controller 106-2 can alter settings of the access points 102-1, 102-2, 102-3 for the connection between the plurality of access points 102-1, 102-2, 102-3 and the controller 106-2 without altering settings of the access points 102-1, 102-2, 102-3 and the controllers 106-1, 106-3.

    [0015] In some examples, the plurality of controllers 106-1, 106-2, 106-3 can each utilize an encryption and/or decryption method. In some examples, each of the plurality of controllers 106-1, 106-2, 106-3 can utilize a different encryption and/or decryption method. For example, controller 106-1 can utilize a first type of encryption method for data packets received from or sent to the plurality of access points 102-1, 102-2, 102-3 and controller 106-2 can utilize a second type of encryption method for data packets received from or sent to the plurality of access points 102-1, 102-2, 102-3. In these examples, the plurality of controllers 106-1, 106-2, 106-3 can utilize different encryption and/or decryption methods such that data packets to be sent to controller 106-1 are not capable of being decrypted by controller 106-2. These examples can increase security between the plurality of controllers 106-1, 106-2, 106-3.

    [0016] In some examples, the plurality of zones 104-1, 104-2, 104-3 can include service controllers (SC) 110-1, 110-2. In some examples, each of the plurality of zones 104-1, 104-2, 104-3 can include a corresponding service controller 110-1, 110-2. In some examples, the service controllers 110-1, 110-2 can correspond to controllers 106-1, 106-2 within the corresponding zones 104-1, 104-2. For example, zone 104-1 can include a controller 106-1 and a corresponding service controller 110-1. In some examples, service controllers 110-1, 110-2 can generate security protocols for the corresponding controllers 106-1, 106-2. In some examples, the service controllers 110-1, 110-2 can be utilized to define security protocols for a corresponding zone 104-1, 104-2. In some examples, the service controllers 110-1, 110-2 can be utilized to alter security protocols or other security settings for the corresponding zone 104-1, 104-2.

    [0017] In some examples, the plurality of zones 104-1, 104-2, 104-3 can be organized in a hierarchy with primary zones with higher priority over secondary zones. For example, zone 104-1 can have priority over zone 104-2. For example, the controller 106-1 can be a primary zone that includes administrative control and/or management over the plurality of access points 102-1, 102-2, 102-3. In this example, administrative settings for the plurality of access points 102-1, 102-2, 102-3 may be altered by the controller 106-1 while the administrative settings may not be altered by controllers 106-2, 106-3.

    [0018] As used herein, administrative settings for the plurality of access points 102-1, 102-2, 102-3 can include, but is not limited to debug logs, common information logs, troubleshooting settings, management settings, quantity of zones settings, radio configuration, channel configuration, multi-connection profile, reboot capabilities for the controllers 106-1, 106-2, 106-3, reboot capabilities for the access points 102-1, 102-2, 102-3, and/or other administrative settings that may not affect settings of the other zones 104-2, 104-3. For example, the controller 106-1 can alter a quantity of zones for the plurality of access points 102-1, 102-2, 102-3. In some examples, the zone 104-2 can be a secondary zone that does not have priority over zone 104-1. In this example, controller 106-2 of zone 104-2 can connect to the plurality of access points 102-1, 102-2, 102-3 after the controller 106-1 of zone 104-1 connects to the plurality of access points 102-1, 102-2, 102-3. In this example, the controller 106-2 of zone 104-2 can receive the multi-connection configuration from the controller 106-1. As used herein, the multi-connection configuration can include the administrative settings as described herein for the environment 100. In some examples, the controller 106-2 can be restricted to providing tunnel mode for the plurality of access points 102-1, 102-2, 102-3. In this way the environment 100 may not experience counteractive settings or setting changes that negatively affect the environment 100.

    [0019] The environment 100 can be utilized to enable the plurality of access points 102-1, 102-2, 102-3 to have multiple zones 104-1, 104-2, 104-3 that are managed by corresponding controllers 106-1, 106-2, 106-3. In some examples, the multiple zones 104-1, 104-2, 104-3 can be separated by air gaps to prevent data packets from being decrypted by an incorrect controller. In some examples, the environment 100 can be utilized to enable a first controller for a first type of data and enable a second controller for the same access points for a second type of data. In this way, an organization can separate the management of secure data from unsecure data. In another way, multiple organizations can utilize the environment 100 to limit a quantity of access points within an area while maintaining security and separation between the multiple organizations.

    [0020] Figure 2 further illustrates an example method 220 for multi-connection access point, consistent with the present disclosure. In some examples, the method 220 can be utilized to generate the multi-connection access point environment 100 as referenced in Figure 1. For example, the method 220 can be a multi-connection configuration of a plurality of access points and/or a plurality of controllers. The method 220 can be executed by an access point 202 and/or a number of zones 204-1, 204-2, 204-3 with corresponding controllers as described herein.

    [0021] At 222, the method 220 can include the access point 202 connecting to a controller corresponding to zone 204-1. As described herein, the number of zones 204-1, 204-2, 204-3 can be in a hierarchy. For example, zone 204-1 can be considered a primary zone (PZ) when the zone 204-1 is a top zone within the hierarchy. For example, the zone 204-1 can be utilized to manage administrative settings for the access point 202 as described herein. In some examples, the controllers corresponding to zone 204-1 can: be a first zone to connect with the access point 202, have full control of the access point 202, have radio control over the access point 202, have channel configuration control over the access point 202, and/or control other features of the access point 202. In some examples, a controller corresponding to zone 204-1 can configure internet protocols (IPs) for controllers corresponding to zone 204-2 and/or zone 204-3.

    [0022] At 224-1, the method 220 can include notifying, by the controller corresponding to the zone 204-1, the IPs for controllers corresponding to zone 204-2 and/or zone 204-3. The access point 202 can receive the notification from the controller corresponding to zone 204-1. At 224-2, the method 220 can include the access point 202 performing an access point self-check. At 224-3, the method 220 can include the access point 202 determining an ESSID assignment table (EAT) allocation based on the notification and/or self-check.

    [0023] At 226-1, the method 220 can include the controllers corresponding to zone 204-1 configuring virtual access points for controllers corresponding to zone 204-2 and/or zone 204-3. As used herein, a virtual access point is an emulation of an access point. In some examples, the access point 202 can include a plurality of virtual access points that each can virtually act as individual physical access points. At 226-2, the method 220 can include the access point 202 starting the virtual access points for zone 204-1. In some examples, starting the virtual access point for zone 204-1 can include starting communication of data packets between the access point 202 and the controllers corresponding to zone 204-1. In some examples, the access point 202 can start the virtual access points for the zone 204-1 based on the configuration from zone 204-1 at 226-1.

    [0024] At 228, the method 220 can include the access point 202 sending a zone flag (e.g., data zone (DZ) flag, etc.) to zone 204-2. In some examples, the access point 202 can simultaneously send a zone flag to zone 204-2 and zone 204-3. In these examples, the access point 202 can start virtual access points for a zone that responds to the zone flag first. For example, controllers corresponding to zone 204-2 can send configuration data to the access point 202 in response to the zone flag sent at 228 before controllers corresponding to zone 204-3 can respond.

    [0025] At 232, the method 220 can include the access point 202 starting virtual access points for controllers corresponding to zone 204-2. As described herein, starting the virtual access points for the controllers corresponding to zone 204-2 can include starting communication of data packets between the access point 202 and controllers corresponding to zone 204-2. In some examples, the controllers corresponding to zone 204-2 can be data zone (DZ) controllers that are lower in the zone hierarchy compared to zone 204-1. That is, the controllers corresponding to zone 204-2 can include limited capabilities. For example, the controllers corresponding to zone 204-2 may not be able to reboot the access point 202, provision the access point 202, and/or upgrade an image of the access point 202.

    [0026] At 234, the method 220 can include the access point 202 sending a zone flag (e.g., data zone (DZ) flag, etc.) to zone 204-3. In some examples, the controllers corresponding to zone 204-3 can respond at 236 with configuration data for virtual access points for the controllers corresponding to zone 204-3. For example, controllers corresponding to zone 204-3 can send configuration data to the access point 202 in response to the zone flag sent at 234.

    [0027] At 238, the method 220 can include the access point 202 starting virtual access points for controllers corresponding to zone 204-3. As described herein, starting the virtual access points for the controllers corresponding to zone 204-3 can include starting communication of data packets between the access point 202 and controllers corresponding to zone 204-3. In some examples, the controllers corresponding to zone 204-3 can be data zone (DZ) controllers that are lower in the zone hierarchy compared to zone 204-1. That is, the controllers corresponding to zone 204-3 can include limited capabilities. For example, the controllers corresponding to zone 204-3 may not be able to reboot the access point 202, provision the access point 202, and/or upgrade an image of the access point 202.

    [0028] Figure 3 illustrates an example architecture 340 for multi-connection access point, consistent with the present disclosure. In some examples, the architecture 340 can represent a networking environment such as environment 100 as illustrated in Figure 1. The architecture 340 can illustrate an access point 302 connected to a plurality of zones 304-1, 304-2, 304-3 with corresponding controllers (e.g., controller 306-1, 306-2, 306-3 and/or service controllers 310-1, 310-2, etc.).

    [0029] The access point 302 can include a station 342. As used herein, a station 342 is a device that can utilize networking protocols (e.g., IEEE 802.11, etc.). In some examples, the access point 302 can be configured to generate a plurality of virtual access points from the station 342. As used herein, a virtual access point is an emulation of the access point 302. In some examples, the virtual access points for each of the plurality of zones 304-1, 304-2, 304-3 can include: a number of control plane security (CPSec) engines 344-1, 344-2, 344-3 for controllers 306-1, 306-2, 306-3, control plane security engines 346-1, 346-2 for service controllers 310-1, 310-2, and/or basic service set (BSS) engines 348-1, 350, 348-2, 348-3. As used herein, a BSS includes the access point 302 and associated station 342.

    [0030] In some examples, the zone 304-1 can include a controller 306-1 coupled to CPSec engine 344-1, BSS engine 348-1, and/or BSS engine 350. In some examples, the zone 304-1 can include a service controller 310-1 coupled to CPSec engine 346-1, BSS 348-1, and/or BSS engine 350. In some examples, the zone 304-1 can be a primary zone as described herein.

    [0031] In some examples, the zone 304-2 can include a controller 306-2 coupled to CPSec engine 344-2, and/or BSS engine 342-2. In some examples, the zone 304-2 can include a service controller 310-2 coupled to CPSec engine 346-2 and/or BSS engine 348-2. In some examples, the zone 304-2 can be a data zone as described herein. In some examples, the zone 304-3 can include a controller 306-3 coupled to CPSec engine 344-3 and/or BSS engine 348-3. In some examples, the zone 304-3 may not include a service controller. In some examples, the zone 304-3 can be a data zone as described herein.

    [0032] Figure 4 is a block diagram of an example system 450 for multi-connection access point, consistent with the present disclosure. The system 450 may include a computing device that is capable of communicating with a remote system. In the example of Figure 4, the system 450 includes a processing resource 452 and a memory resource 454. The memory resource 454 may store readable instructions to cause the processing resource 452 to perform a number of operations. Although the following descriptions refer to a single processing resource and a single memory resource, the descriptions may also apply to a system with multiple processing resources and multiple memory resources. In such examples, the instructions may be distributed across multiple memory resources and the instructions may be distributed across multiple processing resources. Put another way, the instructions may be stored across multiple machine-readable storage mediums and executed across multiple processing resources, such as in a distributed computing environment.
