Embodiment

[0035] Such as figure 1 As shown, a method for realizing fast centralized forwarding in a wireless hotspot controller includes the following steps:

[0036] 1) CAPWAP tunnel decapsulation, this step includes the following sub-steps:

[0037] 11) set up flow table, this step comprises:

[0038] 111) Create an incomplete flow entry: After the physical drive receives the CAPWAP-encapsulated message, the figure 2 Create FLOW at the position marked with 1, and record the physical port, source and destination MAC addresses, and source and destination IP addresses of the received message, and create an incomplete flow entry;

[0039] 112) Set AP FLOW: During the process of sending CAPWAP to CAPWAP driver (in figure 2 4), find incomplete flow entries according to the source and destination IP addresses, set the type to AP FLOW, and record CAPWAP information;

[0040] 113) Mark incomplete entries: in figure 2 In the position marked with 5, if the received message is an IPv4 mes...

Abstract

The invention relates to a method for realizing fast centralized forwarding in a wireless hotspot controller, comprising the following steps: 1) CAPWAP tunnel decapsulation, the step comprising the following sub-steps: 11) establishing a flow table; 12) forwarding the flow table; 2) CAPWAP Tunnel encapsulation, this step includes the following sub-steps: 21) establishing a flow table; 22) forwarding the flow table; compared with the prior art, the present invention has the advantages of improving efficiency, saving time, and having a wide range of applications.

Description

technical field [0001] The invention relates to a method for forwarding messages of a wireless hotspot controller, in particular to a method for realizing fast centralized forwarding in the wireless hotspot controller. Background technique [0002] Centralized forwarding of wlan user data, wireless hotspot controller as the aggregation point of all data, has very high performance requirements, and hardware upgrades will inevitably bring about cost increases. The method of this patent can greatly improve the data forwarding performance of the wireless hotspot controller under the condition that the hardware conditions remain unchanged. [0003] During the packet forwarding process, user packets are forwarded in a centralized manner, and multiple tables such as the Layer 2 forwarding table, routing table, ARP table, and user table must be checked to complete one forwarding. [0004] When the user message arrives at the wireless hotspot controller, there is a CAPWAP tunnel, an...
