What is Mesh network?
Today, we will give you a detailed introduction to what kind of technology Mesh network is.
What is Mesh network?
Since the birth of the 1960s, the development of network technology is extremely rapid. The star structure, ring structure, bus structure, distributed structure, and tree structure of traditional LAN have all played a role in various fields, providing stable network connection and a large amount of data traffic for billions of people around the world.
However, there is such a LAN technology, it was born very early, but because of the complex structure, has not been paid attention to. However, with the development of wireless network technology today, its advantages are re-emphasized. This type of network is mesh network.
Typical Mesh Structure
The topology of a mesh network is as follows: All nodes on the network are connected to each other, and each node is connected to at least two other nodes. All nodes form an entire network. In the wired era, it is very difficult to implement a mesh network because of the existence of network cables. However, in the wireless era, the layout of the wireless mesh network is relatively easy because the network cable is freed from the fetters of the network cable and the application of various new technologies.
Features of the Mesh Network
In terms of the network topology, a wireless mesh network has the following features:
All the nodes in the LAN are connected together, and there are multiple connection channels between any two nodes, which show obvious decentralization. The consists of a group of wireless APs that are distributed in a network. The APs are interconnected through wireless relay links in point-to-point mode to expand the wireless “hot spots” in a traditional WLAN into wireless “hot spots” that cover a large area.
Self-configuration and self-healing
APs on a wireless mesh network can be automatically configured and managed in a centralized manner, simplifying network management and maintenance. In addition, APs on a wireless mesh network can be automatically discovered to eliminate the impact of single points of failure on services and provide redundant paths.
Expands the coverage of traditional WLAN hotspots to a larger coverage of hotspots, eliminating the bandwidth decrease caused by the increasing distance of the existing WLAN. In addition, the system using the Mesh structure can avoid the interference of obstacles, so that the signal transmission is unimpeded, and the blind area is eliminated.
High utilization is another technical advantage of Mesh networks. On a single-hop network, a fixed AP is shared by multiple devices. As the number of network devices increases, the availability of the communication network of the AP decreases greatly. On a Mesh network, each node is an AP. Therefore, this problem does not occur. Once the availability of an AP decreases, data is automatically reselected to another AP for transmission.
Wireless Mesh networks have outstanding advantages. In terms of coverage area and performance, wireless Mesh networks have excellent network coverage. It also expands on features that involve security, stability, and high bandwidth.
