APPARATUS AND METHODS FOR AUTHENTICATING VOICE AND DATA DEVICES ON THE SAME PORT

摘要

In one embodiment, a method is disclosed. A first non-domain packet that does not specify a domain is received from a first device. A first authentication packet is sent to the first device to thereby attempt a first authentication process for allowing the first device to access a network via a particular access port. If the first device cannot participate in the first authentication process, the following operations are performed: (i) if the first device or a user of the first device is authorized to access a voice first domain, forming a first binding between an identity of the first device and the first domain, wherein the first binding specifies that the first device is allowed to access the first domain; (ii) if the first device or the user of the first device is authorized to access the voice first domain and if the first device is determined to be a voice type device and if the first device is not aware of the first domain yet, forming a second binding between the identity of the first device and a data second domain, wherein the second binding specifies that the first device is allowed to access the second domain; (iii) if the first device or the user of the first device is authorized to access the data second domain, forming a third binding between the identity of the first device and the second domain, wherein the third binding specifies that the first device is allowed to access the second domain; and (iv) if a first domain packet that specifies the first domain is received from the first device, removing the second binding if it is present. If the first device can participate in the first authentication process, performing operations (i) through (iii) only if the authentication process succeeds for the first device.
