Methods for controlling a traffic of an authentication server

An authentication access apparatus, the authentication access apparatus comprising:

• a processor;
• and
• a memory on which stored machine readable instructions to cause the processor to:
• receive a request message from an authentication client in a local area network, wherein the authentication client belongs to a sub local area network of the local area network;
• detect a priority of the authentication client and determine a sub local area network token bucket corresponding to the sub local area network to which the authentication client belongs;
• and
• in response to the authentication client having a high priority, allocate a token from a high priority token bucket of the sub local area network and redirect the request message to the authentication server;
• in response to the authentication client having a low priority,
• allocate a token from a low priority token bucket of the sub local area network if the token is available in the low priority token bucket and redirect the request message to the authentication server;
• in response to the token not being available in the low priority bucket, one of:
• allocate a token from a shared token bucket of the local area network if the token is available in the shared token bucket and redirect the request message to the authentication server, and
• discard the request message in response to a token not being available in the shared token bucket;
• and
• recover the allocated token after a successful authentication of the authentication client.

A non-transitory computer readable storage medium storing machine-readable instructions that when executed by a processor, cause the processor to:

• receive a request message from an authentication client in a local area network, wherein the authentication client belongs to a sub local area network of the local area network;
• detect a priority of the authentication client and determine a sub local area network token bucket corresponding to the sub local area network to which the authentication client belongs;
• in response to the authentication client having a high priority, allocate a token from a high priority token bucket of the sub local area network and redirect the request message to the authentication server;
• in response to the authentication client having a low priority,
• allocate a token from a low priority token bucket of the sub local area network if the token is available in the low priority token bucket and redirect the request message to the authentication server;
• in response to the token not being available in the low priority bucket, one of:
• allocate a token from a shared token bucket of the local area network if the token is available in the shared token bucket and redirect the request message to the authentication server, and
• discard the request message in response to a token not being available in the shared token bucket;
• and
• recover the allocated token after a successful authentication of the authentication client.
