Methods and apparatus for separate control and data planes in a wireless network

摘要

In some embodiments, an apparatus includes a wireless access point controller configured to receive information associated with a topology of a network including information associated with which access switch from a set of access switches each virtual local area network (VLAN) from a set of VLANs is associated. The wireless access point controller is configured to associate each VLAN from the set of VLANs with a unique tunnel identifier from a set of tunnel identifiers. The wireless access point controller is configured to provide each wireless access point from a set of wireless access points control information including the set of tunnel identifiers such that a wireless access point from the set of wireless access points can send a data packet received from a wireless device to an access switch from the set of access switches associated with a destination VLAN from the set of VLANs using the tunnel identifier associated with the destination VLAN.

主权项

1. An apparatus, comprising:
a wireless access point controller configured to receive information associated with a topology of a network including information associated with which access switch from a plurality of access switches each virtual local area network (VLAN) from a plurality of VLANs is associated, the wireless access point controller configured to associate each VLAN from the plurality of VLANs with a unique tunnel identifier from a plurality of tunnel identifiers, the wireless access point controller configured to provide each wireless access point from a plurality of wireless access points a first control information including the plurality of tunnel identifiers such that a first wireless access point from the plurality of wireless access points can send a data packet received from a wireless device to an access switch from the plurality of access switches associated with a destination VLAN from the plurality of VLANs using the unique tunnel identifier associated with the destination VLAN, the wireless access point controller configured to provide a second control information to each access switch from the plurality of access switches such that the access switch from the plurality of access switches encapsulates the data packet, using the second control information, prior to forwarding the data packet to a second wireless access point from the plurality of wireless access points and associated with a destination device.
