Software for managing access control functions in a network. The software includes a host that receives access control commands or information and calls one or more methods. The methods perform access control functions and communicate access control results or messages to be transmitted. The host may be installed in a network peer seeking access to the network or in a server controlling access to the network. When installed in a peer, the host receives commands and exchanges information with a supplicant. When installed in an access control server, the host receives commands and exchanges information with an authenticator. The host has a flexible architecture that enables multiple features, such as allowing the same methods to be used for authentication by multiple supplicants, providing ready integration of third party access control software, simplifying network maintenance by facilitating upgrades of authenticator software and enabling access control functions other than peer authentication.

Systems and methods for use in communication between a client and a server, via a networking device, are provided. The method may include sending a request to establish a data connection from the client to the server via the networking device, setting a data connection keep-alive interval for the data connection to a predetermined safe value, and sending a request to establish a test connection between the client and the server. The method may further include determining an efficient keep-alive interval for communication between the client and server via the networking device, using the test connection, setting the data connection keep-alive interval to the efficient keep-alive interval determined using the test connection, and uploading the efficient keep-alive interval from the client to the server in an efficient keep-alive interval notification message, for communication to other clients connected to the server.
