Abstract

The present disclosure is generally related to a method for wireless software-defined networking. The method includes establishing a wireless link between an access point of a network and a plurality of client devices. The method includes generating a time schedule. The time schedule allocates a time window to each of the plurality of client devices. Each time window defines when a plurality of client devices is allowed to communicate within the network via the access point.

First claim

What is claimed is:

1 . A network computer system, comprising:
a controller to manage a network; an access point to communicatively couple to the controller, the access point to wirelessly couple with a plurality of client devices; wherein the controller is to generate a time schedule, the time schedule to allocate a time window to each of the plurality of client devices, each time window defining when a number of client devices is allowed to communicate within the network via the access point.

2 . The network computer system of claim 1 , wherein the time schedule is generated based on traffic flow data received via a software-defined network (SDN) application programming interface (API) from the plurality of client devices.

3 . The network computer system of claim 2 , the controller to modify the time schedule in response to traffic flow data received from the plurality of client devices.

4 . The network computer system of claim 1 , the controller to send a network policy to one of the plurality of client devices wirelessly using a software-defined network (SDN) application programming interface (API).

5 . The network computer system of claim 1 , the controller to send a network policy to one of the plurality of client devices wirelessly using a software-defined network (SDN) application programming interface (API), along with a Network Allocation Vector (NAV) mechanism to control wireless transmissions of non-SDN enabled client devices with the network via the access point.

6 . The network computer system of claim 1 , comprising a plurality of access points, wherein the controller is to allocate an access window to each of the plurality of access points, each access window defining when the corresponding access point is allowed to enable wireless communication between the access point and the client devices wirelessly coupled to the access point.

7 . A client device wireless coupled to a network, comprising:
a local controller to communicate with the network via an access point and to receive a time window via a software-defined network (SDN) application programming interface (API) from a network controller in the network; and a traffic scheduler to schedule wireless communication within the network to occur during the time window.

8 . The client device of claim 7 , comprising a flow manager to enforce a network policy received from the network.

9 . The client device of claim 8 , the flow manager to measure traffic flow data in the client device.

10 . A method, comprising:
establishing a wireless link between an access point of a network and a plurality of client devices; and generating a time schedule, the time schedule to allocate a time window to each of the plurality of client devices, each time window defining when a number of client devices is allowed to communicate within the network via the access point.

11 . The method of claim 10 , comprising generating the time schedule based on traffic flow data received from the plurality of client devices via a software-defined network (SDN) application programming interface (API).

12 . The method of claim 11 , comprising modifying the time schedule in response to traffic flow data received from the plurality of client devices.

13 . The method of claim 11 , comprising sending a network policy to one of the plurality of client devices wirelessly using a software-defined network (SDN) application programming interface (API).

14 . The method of claim 11 , comprising sending a network policy to one of the plurality of client devices wirelessly using a software-defined network (SDN) application programming interface (API), along with a Network Allocation Vector (NAV) mechanism to control wireless transmissions of non-SDN enabled client devices with the network via the access point.

15 . The method of claim 11 , comprising allocating an access window to each of a plurality of access points in the network using a software-defined network (SDN) application programming interface (API), each access window defining when the corresponding access point is allowed to enable wireless communication between the access point and the access point's client devices.
