Embodiment Construction

[0023] Please refer to figure 1 It is a schematic diagram of a branch office network. The branch office includes an AC, a modem (modem), an AP, and a terminal. The AP can provide services for one or more terminals at the same time. In this embodiment, only one terminal is taken as an example. AP and AC provide both internal network access and external network access services for terminals, and AP and AC are connected through a modem. If it is necessary to provide users with access to the external network and the internal network at the same time, the AC needs to provide two SSIDs. One SSID supports centralized forwarding and access to the company internal network; the other SSID directly forwards locally and accesses external network traffic. To meet the needs of accessing the external network and the internal network by switching the SSID, it will cause complicated operations for users and bring inconvenience to use. Therefore, users need to use the same SSID to access both ...

Abstract

The present invention provides a message forwarding method and device, so that when an AP receives a data message sent by a terminal, it obtains a flow table issued by an AC through an openflow channel, and the flow table includes a first matching item and a second matching item; when the data When the destination IP address of the packet matches the first matching item, according to the action item corresponding to the first matching item, the data packet is encapsulated in a CAPWAP tunnel and then forwarded to the AC, so that the AC determines that the data packet is not of the default protocol type Forwarding the data packet to the intranet; when the protocol type of the data packet matches the second matching item, according to the action item corresponding to the second matching item, the data packet is encapsulated in a CAPWAP tunnel and then forwarded to the AC, so that when the AC determines that the data packet is a packet of a preset protocol type, it obtains an IP address for the terminal; when the data packet does not match any matching item, it forwards the data packet to the external network. Therefore, the user can simultaneously access the external network and the internal network through the same SSID.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message forwarding method and device. Background technique [0002] With the popularization of WLAN (Wireless LAN, wireless local area network), the demand for industry scenarios is becoming more and more obvious, and the usage scenarios of headquarters plus branches are more common. In this scenario, the headquarters needs to perform comprehensive network management, while the branch offices need to meet the dual requirements of users accessing the external network and the company's internal network. [0003] In the current branch office implementation scheme, AP (Access Point, access point) can be registered with AC (Access Control, access controller) through CAPWAP (Controlling and Provisioning of Wireless Access Point, wireless access point control and supply), AC provides two SSIDs (Service Set Identifier, Service Set Identifier), one of which supports cent...
