The Internet of Vehicles has always been a hot topic that has received much attention and is the focus of the world's top information technology experts. Internet of Vehicles is a necessary way to achieve green transportation. In the "Internet of Vehicles" era, cars can be driven automatically. There are no signal lights, no jams, and no accidents on the road ... Such a perfect driving life depends on an invisible network. Regulation, this network is "Internet of Vehicles." A comprehensive system solution to solve the relationship between vehicles and vehicles, vehicles and roads, and vehicles and people makes the transportation system intelligent and improves the efficiency of the entire society. Nowadays, the Internet of Vehicles, which is in its infancy, is developing rapidly. Traffic jams in first-tier cities in China are extremely serious. To solve this problem, the establishment of Internet of Vehicles must be promoted.
According to statistics, China has become the world's largest automobile market. According to the current development speed of China's automobile industry, it is expected that the number of vehicles in 2020 will exceed 200 million. The huge automobile market provides a strong foundation for the growth of China's Internet of Vehicles services. For road traffic safety, governments at all levels hope to effectively alleviate traffic pressure through Internet of Vehicles. At the same time, Internet of Vehicles will completely change the mode of human travel and redefine the DNA of cars. The future urban traffic that realizes the Internet of Vehicles technology will bid farewell to a series of problems such as traffic lights, congestion, traffic accidents, and difficult parking, and realize autonomous driving.
With the promotion of the automotive industry chain, China's Internet of Vehicles is facing an explosive development opportunity for the entire industry in the future! At the same time, it has also ushered in a lot of attention and more support policies, which has been included in the country's major special project and become the "12th Five-Year Plan" During the key projects during this period, the Ministry of Industry and Information Technology will start from various aspects such as industrial planning and technical standards, and increase support for in-vehicle information services to promote the full-scale development of the automotive Internet of Things industry. As new energy vehicles are included in the country's seven strategic new industries to accelerate cultivation and development, it is expected that the growth potential of the connected car industry will be further released. According to the estimation of relevant departments, the output value of the connected car industry is expected to exceed 100 billion yuan in the next five years. China is expected to develop into the world's largest vehicle information service market.
Regarding the future development trends and hot topics of concern in the Internet of Vehicles, the China Wireless World and Internet of Things Conference held on November 3-4, 2011 will focus on the market hotspots such as the Internet of Vehicles. This conference is jointly organized by Tiandi Interconnection Corporation, Wi-Fi Technology Alliance, Bluetooth Technology Alliance, ZigBee Technology Alliance and other international technical organizations. It is the most authoritative seminar in China including the traditional international conference on the development of WLAN and personal area network technology industries. The conference attracted many people from various government departments, automobile manufacturers, telecom / broadcast operators, software and hardware manufacturers, TSP / SP / CP, scientific research institutions, investment institutions, etc., and also attracted the attention of the media from all walks of life , Live webcasts and special reports from mainstream online media, sharing and promoting technological innovation in the field of wireless technology, creating a better information interaction platform for the entire industry, and exploring future market opportunities for wireless technology.
The 2011 China Wireless World Internet of Things Conference was strongly supported by the Radio Administration Bureau of the Ministry of Industry and Information Technology, the China Communications Standardization Association, the China Electronics Standardization Institute, the China Radio Association, the China Intelligent Transportation Technology Application Committee, and telecom operators. Including Wi-Fi Alliance, Bluetooth SIG, ZigBee Alliance, NFC Forum, RFID Industry Alliance and other global authoritative technical standards organizations and industry alliances, effectively gather industry enterprises and experts, build the most professional and comprehensive The role of communication platforms. I believe that the 2011 China Wireless World and Internet of Things Conference will become the most valuable platform for China to discuss the development of wireless technology and Internet of Vehicles, and will actively promote the integration of the industrial chain and promote the popularization and deployment of various related technologies in China and around the world!
A Network switch is a type of network device used to connect multiple devices in a local area network (LAN). It can receive and forward data packets through physical or wireless interfaces, sending data packets from the source device to the target device. Network switches can identify and forward packets based on MAC addresses so that data can be accurately transmitted to the target device.
A network switch usually has multiple ports, each of which can connect to a device, such as a computer, server, printer, etc. When a device sends a packet, the switch forwards the packet to the corresponding port according to the MAC address of the target device, thus achieving communication between devices.
The network switch can also divide the virtual local area network (VLAN) into multiple logical subnets, so that different devices can communicate independently on the same physical network, improving network security and performance.
In short, a network switch is a network device used to connect and forward packets, which can realize communication and network management between devices. It is an important part of building local area networks and enterprise networks.
