Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be understood that the step numbers used herein are for convenience of description only and are not intended as a limitation on the order in which the steps are performed.
As shown in fig. 1, fig. 1 is a specific flow chart of a method for seamless roaming in a Mesh network according to an embodiment of the present invention, where the method for seamless roaming in a Mesh network includes steps S1 to S3, and is described in detail as follows:
step S1, receiving a data packet sent by an STA, and identifying whether the data packet belongs to the existing Internet connection or not by a first CPE gateway;
In this step, after the STA accesses the first CPE gateway, the STA sends a data packet to the first CPE gateway, and the first CPE gateway identifies the data packet through the STA connection record database, and identifies whether there is an existing internet connection record in the STA connection record database that is responsible for transmitting the data packet.
If the Internet connection record of the data packet exists, the data packet belongs to the existing Internet connection;
If there is no internet connection record of the data packet, the data packet does not belong to the existing internet connection.
The STA connection record database runs on a specific CPE gateway or a dedicated device in the Mesh networking. The STA connection record database stores all STA roaming information and active Internet connection records, and the stored information comprises the CPE gateway for establishing connection, the IP addresses of the STA and the connection destination and a network interface. The internet connection record needs to be updated in real time according to the latest data reported by each CPE gateway.
Further, in some embodiments, each CPE gateway in the Mesh networking and the access device STA using WiFi are connected in the MAC layer and the IP layer, and the configuration of the local area network addresses of all the CPEs and the STAs in the Mesh networking is kept unchanged all the time, so that roaming of the STAs among the CPEs can be automatically connected to the optimal CPE gateway, and meanwhile, the local area network IP of the STA is unchanged.
To better illustrate how the present embodiment implements the technical solution of the present invention, fig. 2 provides a typical deployment application scenario diagram of a method of seamless roaming in a Mesh network, where fig. 2 includes only 3 CPE gateways for convenience. As shown in the figure, the Mesh networking is implemented by multiple CPE gateways, the STA accesses to the CPE2 through WiFi, the CPE gateway sends the data packet of the STA to the internet through cellular connection, and the STA connection record database is deployed in the CPE 1.
Step S2, if the data packet belongs to the existing Internet connection, a first CPE gateway obtains a first Internet connection to which the data packet belongs through an STA connection record database, and forwards the data packet according to the first Internet connection, so that the data packet is sent to the Internet by the CPE gateway connected with the first Internet;
In the step, if the first CPE gateway searches through the STA connection record database to obtain the Internet connection record of the data packet; and determining a first Internet connection to which the data packet belongs and a CPE gateway connected with the first Internet according to the Internet connection record of the data packet, and forwarding the data packet to the CPE gateway connected with the first Internet by the first CPE gateway so that the CPE gateway connected with the first Internet sends the data packet to the Internet.
After determining the first internet connection to which the data packet belongs, the first CPE gateway adjusts its own routing strategy, and forwards all data packets which belong to the first internet connection and are received later to the second CPE gateway which establishes the first internet connection until the first internet connection is closed; and when the first internet connection is closed, the second CPE gateway deletes the internet connection record of the first internet connection in the STA connection record database after completing the forwarding of the last data packet when recognizing the event.
To better describe the process of forwarding the data packet by the first CPE gateway in the case of an existing internet connection for the data packet, fig. 3 provides a seamless roaming scenario diagram of a method for seamless roaming in a Mesh network. As shown, STA sends data packets to CPE1, and when CPE1 recognizes that the data packets belong to the internet connection established by CPE2, CPE1 forwards the data packets to CPE2, and CPE2 sends the data packets to the internet via the existing traffic of STA before switching CPE gateway; when the CPE1 recognizes that the data packet does not belong to any internet connection, the data packet is directly sent to the internet by the CPE1 through a local cellular connection, so that roaming among a plurality of CPE gateways of the STA is realized without influencing data transmission.
Step S3, if the data packet does not belong to the existing Internet connection, the first CPE gateway establishes a second Internet connection for the data packet, and sends the data packet to the Internet according to the second Internet connection;
In this step, if the first CPE gateway cannot search the internet connection record of the data packet through the STA connection record database, the first CPE gateway establishes an internet connection for the data packet to transmit the data packet, and the established internet connection is denoted as a second internet connection. And then the first CPE gateway establishes a second Internet connection record in the STA connection record database according to the second Internet connection, and the Internet connection record stores the IP addresses and network interfaces of the first CPE gateway, the STA and the destination of the data packet. And finally, sending the data packet to the Internet according to the second Internet connection.
Since the first CPE gateway establishes the second internet connection, the first CPE gateway needs to manage the second internet connection in real time.
When the second Internet connection is not closed, the first CPE gateway sends operation information and STA information of the second Internet connection to the STA connection record database according to a preset frequency, so that the STA connection record database updates an Internet connection record of the second Internet connection according to the operation information and the STA information;
when the second internet connection is closed, the first CPE gateway applies for removal of the internet connection record of the second internet connection from the STA connection record database.
