Embodiment 1

[0048] Such as figure 1 As shown, the networking method of this embodiment includes the following three steps:

[0049] Step 1. Multiple devices are connected through Wi-Fi P2P communication to form a network, one of which is the group creator (GO), and the rest of the devices are group members (GC);

[0050] Step 2: The group creator maintains the network and generates a mapping container, then sends the mapping container to all group members and notifies all group members to update. The group creator also generates and maintains a time container (TIME). The data structure of the mapping container and the time container on the GO side is as follows: figure 2 shown.

[0051] Wherein, maintaining the network allows the group creator to obtain status information of all group members in the network, and the status information includes MAC addresses, network addresses, and whether they are online or not. The mapping container (RC) stores the name of each device in the network...

Embodiment 2

[0054] Compared with Embodiment 1, the networking method of this embodiment differs only in that:

[0055] The data stored in the mapping container generated by the group creator in step 2 only includes the name and corresponding MAC address and network address of each device in the network. Moreover, the method for the group creator to maintain the network in step 2 includes active synchronous maintenance, passive synchronous maintenance and offline reconnection maintenance.

[0056] Among them, the active synchronization maintenance means that the group creator regularly synchronizes the whole network, and the whole network synchronization means that the group creator sends the latest mapping container and the corresponding update time point to all group members, and collects the timestamp information fed back by all group members , for maintenance of the mapped container.

[0057] Passive synchronization maintenance means that when a group member joins or disconnects, the ...

Embodiment 3

[0060] Compared with Embodiment 2, the networking method of this embodiment differs only in that:

[0061] The active synchronous maintenance includes the following steps:

[0062] The group creator regularly obtains the network addresses of the registered group members according to the mapping container, and unicasts a synchronization message to all group members one by one, and the synchronization message includes the mapping container and the last update time of the mapping container;

[0063] All group members send a status feedback message to the group creator after obtaining the synchronization message, and the status feedback message includes the timestamp of the last received mapping container;

[0064] After obtaining the status feedback message of each group member, the group creator finds the corresponding entry in the mapping container according to the MAC address, and updates the corresponding timestamp in the container.

[0065] The passive synchronous maintenan...

Abstract

The invention discloses a networking method, a networking system, a multicast method and a multicast system. The networking method includes the steps: connecting a plurality of devices by communication to form a network, taking one device as a group creator and taking the rest devices as group members; maintaining the network by the group creator to acquire state information of all the group members in the network; generating a mapping container by the group creator, transmitting the mapping container to all the group members and informing all the group members of updating; locally storing the received mapping container by all the group members. The state information includes MAC (multi-access computer) addresses, a network address and on-line or off-line states, and the mapping container stores the name of each device in the network, the corresponding MAC addresses and the network address. By the networking method and the multicast method, two optional nodes in the network can realize direct communication after multi-point networking by the aid of Wi-Fi (wireless fidelity) P2P (peer-to-peer) network technology, and inter-node multicast can be realized after networking.

Description

technical field [0001] The invention relates to a networking method and system, and a multicast method and system. Background technique [0002] With the emergence of Wi-Fi P2P network technology and the development of mobile terminals, it is more and more common for mobile terminals to use this technology for point-to-point communication, but it is only limited to point-to-point communication, and does not support direct communication between any node after multi-point networking. In the prior art, there is a lack of a group maintenance protocol supporting Wi-Fi P2P multi-node network communication, so it is difficult to realize direct communication between any two nodes in the network, and it is even more difficult to realize multicast between nodes. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a networking method and system and a multicast method and system in order to overcome the defect in the prior art t...
