ARCHITECTURE FOR SEAMLESS ENFORCEMENT OF SECURITY POLICIES WHEN ROAMING ACROSS IP SUBNETS IN IEEE 802.11 WIRELESS NETWORKS

摘要

In a network which includes a first subnet which includes a home wireless switch which includes at least one first interface, and a second subnet which includes a current wireless switch, a method is provided for applying a first set of original security policies associated with the at least one first interface to a packet transmitted from a particular wireless communication device after the particular wireless communication device roams from the first subnet to the second subnet. A method is also provided for applying a first set of original security policies associated with the at least one first interface to a packet being transmitted to a particular wireless communication device after the particular wireless communication device roams from the first subnet to the second subnet.
