The P2P networking grandly launched by Shanghai ZLAN is a new technology for serial port networking. Different from the traditional TCP/IP connection style based on IP plus port, P2P technology proceeds communication on the basis of device ID. Users only need to input device ID so that can communicate with devices anywhere in the world, without concerning device whether inside or outside network, neither without doing port mapping and concerning IP change. P2P is a distributed network, different from the network based on central server forwarding, it sets up communication among devices, just need the P2P authentication server act as a bridge at the beginning of communication. This way greatly accelerates the communication efficiency between devices, reduce the server load.
The P2P products provided by Shanghai ZLAN include Single Chip, Ethernet/Wifi/3G/4G networking media, can meet omnibearing networking style. Provide two connection mode based on PC: Virtual Serial Port and TCP/IP connections, as well developing software and demo for Android, IOS system. The permission of access to ID can be managed by authentication and user name mode.
When implemented P2P remote access, it can realize multi-users to access one device at the same time, and each user access to the data without interruption from each other, just as realizing multi-host function, also can use P2P to implement Modbus gateway.
Intranet NAT mapper (N2N) corresponds to ZLAN product model ZLAN7144N2, the product has N2N function as Ethernet port to Ethernet port. It can map intranet port to another intranet port, can realize intranet traversal, can easily realize outer net monitoring intranet TCP devices, without mapping on router and installing software on intranet through proxy forwarding way to realize accessing intranet device. ZLAN N2N products provide new path for Ethernet port PLC, Ethernet port touch panel remote monitoring and program download.
