When we talk about the Industrial Internet of Things (IIoT), we often encounter various technical terms.Among them, "Wireless Bridge" is an important concept.It plays a key role in connecting different networks and realizing data communication. So what is Wireless Bridge?In which scenarios is it suitable for application? This article will explain it to you in an easy-to-understand way.
Wireless Bridge is simply a device that connects two or more networks.It acts like a bridge, allowing different networks to communicate and exchange data with each other.Wireless Bridge works at the data link layer and decides whether to forward a packet to another network based on its destination address.This allows the two networks to communicate via Wireless Bridge, even if they use different communication protocols or physical media.
The working principle of Wireless Bridge can be summarized as "store-and-forward".When the Wireless Bridge receives a packet, it first checks the destination address of the packet,It then looks in its address table (also known as a forwarding table) to determine which port the packet should be forwarded to.If the destination address is in the table, Wireless Bridge forwards the packet directly to the appropriate port;If the destination address is not in the table, Wireless Bridge broadcasts the packet to all ports and updates the table.
1. Expand network coverage: When the coverage of one network is limited, multiple networks can be connected through Wireless Bridge.Thereby extending the coverage of the entire network.
2. Enabling communication between different networks: When two networks use different communication protocols or physical media,They can communicate with each other through Wireless Bridge.
3. Improve network security: Wireless Bridge can filter packets based on their source and destination addresses.Thereby preventing illegal access and malicious attacks.
4. Load balancing: In some cases, multiple Wireless Bridges can be used to spread network traffic over different paths,O as to realize load balancing and improve the performance and stability of the network.
Wireless Bridge is an important network device, which can realize the connection and communication between different networks.It explains the concept and working principle of Wireless Bridge in an easy-to-understand way.As well as its applications in expanding network coverage, realizing communication between different networks, improving network security and load balancing.Jing. In practical applications, it is necessary to select the appropriate Wireless Bridge type and configuration mode according to the specific requirements.O as to ensure the stable operation and efficient communication of the network.With the continuous development of industrial Internet of Things, Wireless Bridge will play an important role in more fields.
