The concept of the Internet of Things (IoT) was first proposed in 1999. Although it appears to be the communication connection of physical objects, its core is the interconnection and integration of information. From a research perspective, the technology of IoT can be divided into three layers, known as DCM, where D stands for devices, C for connectivity, and M for management.
The first layer is devices, which require electronic tag chips and receiving terminal devices, including mobile phones, telephones, televisions, and mobile devices. The second layer is connectivity, which refers to the data transmission channel, currently achieved mainly through the Internet, including wireless and wired connections. After the interconnection of objects, management is needed for IoT applications.
Of the three layers of technology, many of the techniques have yet to be implemented. The "connectivity" layer is the most critical part of the relationship between IoT and the Internet. Currently, due to industry barriers between different sectors, information islands exist in different fields, which block the interconnection of information, making it difficult to achieve the "universal interconnection" required by IoT. Cloud connectivity technology is the key technology to break through the bottleneck of the "connectivity" layer of IoT.
It refers to the secure and fastest way to achieve interconnection of networks, delivering applications securely, reliably, and quickly to those who need them in an on-demand and scalable manner.
Cloud direct connect is the comprehensive expression of network connections in the era of cloud computing edge computing. It integrates various modes and technologies such as SaaS, application delivery, and P2P. Each user is equal to a node, realizing a "super node pool" application of a large number of clients. Users only need to establish a connection channel and can securely and quickly obtain the required resources from anywhere through various nodes.
After achieving cloud connectivity, improving connection speed no longer depends solely on local bandwidth resources but on a massive network service. The more users, the more stable and faster the application. The entire Internet is a huge "data relay station," and the more participants, the better the connectivity performance of each participant.
Cloud connectivity has two main characteristics. Firstly, users can obtain required resources anytime, anywhere. As long as they establish a connection channel, users can obtain resources on-demand through a unique pass in any device and any network environment. Secondly, the connectivity performance adopts super node technology, and the security and speed of users obtaining required applications are more guaranteed.
Cloud connectivity platforms will be distributed among various communication networks and the Internet to form a converged network, realizing the interaction and sharing of various information and breaking through the technical bottleneck of the "connectivity layer" in the development of IoT.
For example, drunk driving can be solved through IoT in the future. When the car door opens, it senses the alcohol level of the owner, and the information is transmitted through the chip installed on the car to the road management facility, which is then transmitted to the traffic police department. The traffic police department immediately sends a text message to the owner's phone, reminding them not to drive. If the owner ignores it, the traffic police can determine whether the vehicle's speed is zero and immediately catch up.
In this application, where is "cloud connectivity" reflected? The car, road management facilities, traffic police department, and mobile terminal are all cloud connectivity nodes. The alcohol level and speed of the vehicle are transmitted from the car to the road management facility and then from the road management facility to the traffic police department. Finally, the owner's mobile phone receives the prompt information, and the entire information transmission process is enabled by cloud connectivity.
