Abstract
Techniques that include a network that is configured in the first mode of a reactive mode to respond to a client attempting to access an endpoint of the network by providing information to be sent to a map server and by checking whether at least an IP address associated with the client corresponds to a registration produced for the client by a wireless controller. Further, the network is configured in a second mode of a proactive mode to determine based on a count maintained by a wireless controller of a number of client IP addresses whether to allow access or not to allow access to one or more clients to the network.
Claims20
A method of configuring a network management system, comprising:
- operably coupling a network to a control plane that communicates with a wireless controller;
- registering, by the network management system via an edge node of the network, an access point as a wired endpoint to a map server of the network wherein the registering comprises information of a type of the wired endpoint associated with one or more constraints to the map server via an opaque object;
- in response to a request to the map server for a locater of the access point from the wireless controller, sending by the network management system to the wireless controller, a point of attachment for the access point with opaque data from the opaque object;
- and
- in response to the opaque data sent to the wireless controller, enabling, by the network management system, the wireless controller to maintain a count of a number of client IP addresses associated with clients of the wireless controller to available points of attachment at the network.
A system comprising:
- one or more processors;
- and
- one or more non-transitory computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
- configuring a network in first mode comprising a reactive mode to respond to a client attempting to access an endpoint of the network by providing information to be sent to a map server and by checking whether at least an IP address associated with the client corresponds to a registration produced for the client by a wireless controller;
- and
- configuring the network in a second mode comprising a proactive mode to determine, based on a count maintained by the wireless controller of a number of client IP addresses, whether to allow access or not to allow access to one or more clients to the network.
A method of configuring a network management system, comprising:
- operably coupling a network to a control plane that communicates with a wireless controller;
- registering, by the network management system using an edge node of the network, an access point as a wired endpoint to a map server of the network;
- registering, by the network management system, information using an opaque object, at the access point of a type of the wired endpoint associated with one or more constraints to the map server;
- sending by the network management system to the wireless controller, a point of attachment for the access point by opaque data from the opaque object;
- and
- maintaining, by the wireless controller, a count of a number of client IP addresses with clients to available points of attachment to the network for enabling an allocating of access points to the map server.
