polling, storing, and pushing data. Provide a variety of query, read and write interface.The application layer is mainly human-machine interface (HMI) and various visual function components, such as alarm interface, trend chart, report, chart, place order, change parameter, Chazhi and so on.more : is to adapt to a wide range, such as industrial gateway can support a variety of industry Ethernet, PLC, strong universality, can be applied to a number of

Session 1 ARP Proxy technology1. ARP ProxyThe ARP proxy feature is the L3 layer gateway device for all functions, routers or L3 layer switches. The ARP proxy function uses the ARP protocol's unreliability to replace the terminal to carry on the L3 layer forwarding, because Arp-requst broadcast is L3 layer isolation, therefore needs L3 layer gateway to replace the terminal to carry on the Arp-requst, when th

Server 1. Introduction At present, WAP has become a hot topic in the field of information technology (IT), and there are many articles about it, including all aspects of WAP, such as the protocol stack itself, WAP application and so on. Indeed, WAP is the 21st century's dream of ' surfing the internet ' anytime, and it's one of the best ways to combine wireless with the Internet. WAP application domain is quite rich, its biggest characteristic is the flexibility of system structure and the openn

packets will be handed over to the default gateway for processing, this will inevitably increase the burden on the default gateway, resulting in reduced network efficiency. Therefore, the subnet mask should be set based on the network size. If a network has no more than 254 computers, you can use "255.255.255.0" as the subnet mask. Currently, most local networks will not exceed this number, therefore, "255
