Home Gateway Impact on Smart Home
The home network system adopts a hierarchical network topology structure and is divided into two network segments: a home main network and a home control subnet. The gateway system consists of ASP.NET server components, network connection controls, home elbows, and devices. The home main network is mainly responsible for communicating with the external network, and the devices in the home control subnet communicate with the outside through the sub-gateway and the main gateway. If a home gateway is regarded as an information processing system, the units that make up the system are the devices that are connected to each node of the network. The gateway system consists of ASP.NET server components, network connection controls, a strong gateway, and devices. Reflected in the specific control of the smart home, such as: air conditioning, you can use the WEB interface used by ASP.NET server components to adjust the air conditioning temperature, wind direction and mode.
The home gateway also enables remote management and monitoring of various smart devices in the home network, thereby providing simple maintenance and control of "smart home" products. This range does not limit users, locations, or even network access methods, as long as access to the network access, you can operate common data. But it also caused the problem of user privacy leaks. In this regard, there are also manufacturers in the market to adapt to market demand and develop solutions with good privacy. For example, the design of network connection control technology, etc., can also support the home network architecture of the home network standard protocol to achieve multi-protocol fusion.
Smart Home Gateway and Gateway Standard
The application of the home gateway is not only the access of high-speed Internet, but also brings more service content, videophones with mixed video and audio streams, and other interactive forms of entertainment services, such as online games.
The home gateway will perform intelligent routing algorithms that distribute these streams of information to a variety of devices such as phones, smart appliances, digital televisions, and stereos. Home Smart Gateway connects home security alarms, lighting controls, network appliances, video intercom, network monitoring, home entertainment, telephony, television, computers, and various information and communication terminals to home smart gateways through a variety of high-speed interfaces Up, through the Ethernet local area network interconnection and connection with the property control center, through the residential broadband network, build a digital community intelligent system. Therefore, it is more convenient, faster and more efficient to build a smart home system with a home gateway. The home gateway also needs a larger transmission bandwidth. For a discussion on "Bandwidth Transmission Issues", click:
The home gateway enables bridging/routing, protocol conversion, address management and conversion, firewall, VPN connection, and QoS management. The home gateway has a wireless router gateway, a VOP broadband access gateway, a digital set top box gateway, a home security gateway, a PC home gateway, a DSL router gateway, and a wired multimedia gateway.
Domestic gateway and its standard status
In China, due to the large number of existing home network standards and no uniform standards, the interoperability between devices of different home network protocols has brought some difficulties. The competition between the standards of the home network has made it difficult for home gateways and home appliance manufacturers to choose a protocol as their own product standard. The lack of such a unified protocol standard in the market has led downstream equipment manufacturers to produce equipment according to different interface standards and protocols. It is very difficult to interconnect and interconnect different devices. Conversely, as a manufacturer, manufacturers have a headache because of the specific installation problems caused by the lack of equipment. Therefore, the standards for gateways, network protocols, and devices urgently need to be unified. This is one of the bottlenecks encountered by smart home manufacturers in the popularization of offline products.
The main gateway needs to be compatible with the home network standard protocol. The difficulty lies in how the home gateway implements the conversion of the two protocols, so that the user can manage and control the two different standard protocol devices through the home gateway on the Internet.
The target devices in the home gateway system are divided into two categories: one is a device modified according to the original protocol, and the other is a device supporting a home network standard protocol, and the two types of devices communicate with the gateway according to respective protocols. When the device based on the two protocols interacts with the web page separately, the functions of the gateway are different.
