Embodiment 2

[0067] refer to figure 2 As shown, the present invention provides another WIFI roaming method compatible with bridge acceleration, which is used for Sta to transition WIFI network connection from master AP to slave AP, mainly including the following steps:

[0068] Stp1: Receive the message sent by Sta;

[0069] Stp2: Determine whether a broadcast message is matched;

[0070] Stp3: if yes, report the broadcast message to the core of the main AP;

[0071] Stp4: Obtain the port information of the Sta according to the broadcast message, update the FDB of the main AP; learn and create a new Sta bridge acceleration entry;

[0072] Stp5: Forward the service message received from the Sta according to the new Sta bridge acceleration entry.

[0073] Wherein, step Stp2 specifically includes:

[0074] Stp21: If the message is a broadcast message, it is determined that the broadcast message is matched;

[0075] Stp22: Report the message to the core of the master AP for processing. ...

Embodiment 3

[0088] refer to image 3 As shown, based on Embodiment 1, this embodiment accordingly provides a bridge-accelerated WIFI roaming device 100 for Sta transitioning from a master AP to a slave AP to a WIFI network connection, including:

[0089] Receiving module 10, for receiving the message that Sta sends;

[0090] Reporting module 20, for if matching to arp or dns message, then report described message to the core of master AP;

[0091] Update module 30, for obtaining the port information of described Sta according to arp or dns message, update the FDB of master AP, learn and create new Sta bridge acceleration entry;

[0092] The forwarding module 40 is configured to forward the service message received from the Sta according to the new Sta bridge acceleration entry.

[0093] The specific functions and uses of the above-mentioned modules in this embodiment can refer to the description in Embodiment 1, and will not be repeated here.

[0094] In summary, the present invention ...

Abstract

The invention relates to a WIFI roaming method and device compatible with bridge acceleration, which are used for Sta to transit WIFI network connection from a master AP to a slave AP, and the methodcomprises the following steps: receiving a message sent by Sta; if the arp or dns message is matched, reporting the arp or dns message to a kernel of the main AP; obtaining the port information of theSta according to the arp or dns message, updating the FDB of the main AP, and learning and creating a new Sta bridge acceleration entry; and forwarding the service message received from the Sta according to the new Sta bridge acceleration table entry. According to the method, the problem of abnormal network forwarding can be solved under the condition that the forwarding performance is not influenced, and the roaming experience of a user is effectively improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for WIFI roaming compatible with bridge acceleration. Background technique [0002] WiFi roaming is a kind of STA (Station, wireless workstation) when moving to the critical area of ​​the main AP (Access Point, wireless access point) and the coverage of the secondary AP, the STA associates with the secondary AP and disconnects from the primary AP. and maintain an uninterrupted network connection during the process. Normally, AP devices work in bridge mode, and service packets are not forwarded through the kernel, but directly forwarded through driver software or hardware. The AP device receives Media Access Control (MAC) address information from all its ports, forms a MAC address table and maintains it. When receiving a frame of data, it will decide whether to filter or forward the frame of data according to its own MAC address table. At this...
