301. local distributed network initialization.
The zero clients which are close to each other in physical position establish a P2P (peer to peer) communication link with each other through a WiFi P2P module or a data module, and establish end-to-end links to initially form a local distributed network environment. As shown in fig. 4, the zero client 1 and the zero client 2 in close physical locations establish a communication link with each other through a WiFi P2P module, so as to form a local distributed network environment. Among them, wiFi P2P, i.e., wiFi Direct, is an important technical specification that is introduced by the WiFi alliance, and supports multiple WiFi devices to connect to each other without an AP (wireless access point ).
At the same time or after the local distributed network is formed, the self-organization elects the zero client with the best physical network condition as the management client. The criteria for election is determined by the signal strength of the zero client itself and the link conditions with other zero clients. As the zero client standard changes continuously, the management client will also change accordingly. MasterA as in fig. 4 is the management client.
302. Master interconnect.
As shown in fig. 5, masterA, masterB, masterC, masterD in four local distributed networks establish a connection with each other. Links between masters may also establish P2P communication links with each other through WiFi P2P modules or data modules.
303. The zero client establishes a direct connection with the play source.
304. And (5) dynamically monitoring the transmission link.
305. And (5) adjusting a transmission link.
For the descriptions of steps 304 and 305, the transmission link environments of the zero client and the play source are monitored in real time, and when the transmission link environment of a certain zero client and the play source becomes worse, the Master of the local distributed network where it is located decides the alternative connection link (i.e. the candidate link) thereof. By means of seamless access of the network transmission environment with better alternative relay links, the image transmission quality of the zero client is ensured.
As shown in fig. 6, the whole network monitors the quality of the connection 1 between the zero client and the play source in real time, and the quality of the connection 2 between the other zero clients and the play source in a direct or pull mode. When the connection quality of the candidate link 2 is higher than the current direct connection 1 quality through other zero client combination modes, the candidate link 2 directly and seamlessly replaces the current link 1, and the best link is used in real time to provide service between the zero client and the playing source.
306. And recovering the transmission link.
When the transmission energy of the link network of the zero client is recovered, namely the direct link quality of the zero client is higher than the quality of the candidate link, the candidate link is removed, and the original direct link is recovered to provide service.
The link switching method provided by the embodiment of the disclosure monitors the link quality of a first link of a first client and data transmission equipment and monitors the link quality of at least one alternative link of the first client and the data transmission equipment; acquiring a link set to be switched, wherein the link quality of each alternative link in the link set to be switched is larger than that of the first link; selecting a second link with optimal link quality from the link set to be switched; the communication link of the first client is switched from the first link to the second link.
