Problems solved by technology

[0005] 2) Reliable service: Common network issues such as congestion or temporary interruptions in connectivity can lead to poor service quality
At present, in the multi-media home network networking environment, it often occurs that the devices connected to the multi-media client and the multi-media AP cannot communicate normally.

Embodiment Construction

[0048] Such as figure 2 As shown, in the multimedia home network environment, considering that when the AP sends data packets to the Client and adopts the three-address mode, the three-address mode lacks the destination address of the data packet compared to the four-address mode; when the Client sends data packets to the AP When the three-address mode is used, the three-address mode lacks the source address of the data packet compared to the four-address mode. In this case, if the source address or destination address is forwarded through the WiFi interface, it is the address of the device connected to the multimedia client. When the multi-media AP and the multi-media client are in the three-address mode, because the data packet cannot carry the address of the device connected to the multi-media client when it is forwarded on the WiFi interface, the device connected to the multi-media client and the multi-media AP Uplink or downlink devices cannot communicate normally.

Abstract

Disclosed are a data transmission method, a multi-medium access point and a multi-medium client. The method comprises the following steps: a multi-medium access point (AP) learning a current wireless local area network (WLAN) operating mode of an opposite end multi-medium Client from the opposite end multi-medium client (Client); and the multi-medium AP comparing the address of a target device to which a data packet to be sent is sent with the address of the opposite end multi-medium Client, judging whether both the current WLAN operating mode thereof and the current WLAN operating mode of the opposite end multi-medium Client are three-address modes or not if the addresses are different, and if yes, then determining that the data packet to be sent is prohibited from being sent through a wireless fidelity (WiFi) interface of the multi-medium AP. According to the embodiments of the present invention, a data packet is prohibited from being sent through a WiFi interface, but can be sent through other interfaces such as power line communication (PLC). Thus, normal data communication between hanging devices of a multi-medium Client and a multi-medium AP can be guaranteed.

Description

technical field [0001] The invention relates to the communication field, in particular to a data transmission method, a multimedia access point and a multimedia client. Background technique [0002] The IEEE standardization organization is developing a new P1905.1 standard, such as figure 1 As shown, this standard provides an abstraction layer for various mediums of home network. This abstraction layer is for heterogeneous home network medium such as IEEE P1901 (PLC, power line communication, power line communication), IEEE802.11 (wireless local area network, WLAN ), IEEE802.3 (Ethernet) and MoCA1.1 provide a common control and data plane SAP (Service Access Point, business access point), this abstraction layer can abstract the details of each link in use Specific operating information, and aggregate the data sent and received through different links, so as to realize the seamless connection of various interconnection technologies in the home network. This software layer a...
