Abstract
The present disclosure provides a method for forwarding a packet. When an access point (AP) receives a first packet from a wireless station, the AP may tunnel encapsulate the first packet and send the first packet through a tunnel to a switch which is designated for the AP by an access controller (AC). When the AP receives a packet from the switch through the tunnel, the AP may tunnel de-capsulate the packet to acquire a second packet, and send the second packet to the wireless station according to a forward table.
Claims15
A method for forwarding a packet, includes:
- querying, by an access point (AP), a forward table to determine an egress port for forwarding a first packet received from a wireless station (STA);
- tunnel encapsulating, by the AP, the first packet when the egress port is a pre-created tunnel port,
- sending, by the AP, the tunnel encapsulated first packet to a switch through a tunnel corresponding to the tunnel port, wherein the switch is designated for the AP by an access controller (AC);
- and
- tunnel de-capsulating, by the AP, a tunnel-encapsulated packet received from the switch through the tunnel to acquire a second packet, and
- sending, by the AP, the second packet to the wireless STA according to the forward table.
A method for controlling packet forwarding, includes:
- establishing, by an access controller (AC), a control tunnel with an access point (AP) to manage the AP;
- designating, by the AC, a switch to the AP;
- and
- instructing, by the AC, the AP and the switch to establish a tunnel between the AP and the switch.
An access point (AP), including a processor and a storage medium, wherein the storage medium stores machine readable instructions which are executable by the processor to:
- query a forward table to determine an egress port for forwarding a first packet received from a wireless station (STA);
- tunnel encapsulate the first packet when the egress port is a pre-created tunnel port,
- send the tunnel encapsulated first packet to a switch through a tunnel corresponding to the tunnel port, wherein the switch is designated for the AP by an access controller (AC);
- tunnel de-capsulate a tunnel-encapsulated packet received from the switch through the tunnel to acquire a second packet, and
- send the second packet to the wireless STA according to the forward table.
