Abstract

In some embodiments, an apparatus comprises a core network node and a control module within an enterprise network architecture. The core network node is configured to be operatively coupled to a set of wired network nodes and a set of wireless network nodes. The core network node is configured to receive a first tunneled packet associated with a first session from a wired network node from the set of wired network nodes. The core network node is configured to also receive a second tunneled packet associated with a second session from a wireless network node from the set of wireless network nodes through intervening wired network nodes from the set of wired network nodes. The control module is operatively coupled to the core network node. The control module is configured to manage the first session and the second session.
