Why is a managed industrial switch the best choice for network multicast communication?

One. Managed industrial switch attributes

     Managed industrial switches are a category of industrial Ethernet switches and a new generation of industrial Ethernet switches, that is, Ethernet switch devices used in the field of industrial control. Due to the adoption of network standards, they are open and widely used And the low price, the use of transparent and unified TCP/IP protocol, Ethernet has become the main communication standard in the field of industrial control. Industrial switches have carrier-class performance characteristics and can withstand harsh working environments. The product series is rich and the port configuration is flexible, which can meet the needs of various industries. The product adopts wide temperature design, protection level is not lower than IP30, supports standard and private ring network redundancy protocol.

two. The difference between managed and unmanaged switches

      Managed industrial switches, compared to hubs and unmanaged switches, managed switches have more and more complex functions, and the price is much higher-usually 3 to 4 times that of an unmanaged switch. Managed switches provide more functions and can usually be fully configured through network-based interfaces. It can automatically interact with network devices, and users can also manually configure the network speed and flow control of each port. Some old devices may not be able to use the automatic interaction function, so manual configuration is essential.

     Most managed switches usually also provide some advanced functions, such as SNMP (Simple Network Management Protocol) for remote monitoring and configuration, port mapping for diagnostics, and VLAN (Virtual Local Area Network) for grouping network devices. Priority ranking function to ensure that priority messages pass. With managed switches, redundant networks can be formed. Using a ring topology, managed switches can form a ring network. Each managed switch can automatically determine the optimal transmission path and backup path, and automatically block the backup path when the priority path is interrupted.

 Manageable switches can be managed in the following ways: through RS-232 serial port (or parallel port) management, through a web browser management and through network management software management.

1. Management via serial port

2. Web management

3. Managed by network management software

Third, the advantages of managed switches

      Managed switches can enable Internet Group Management Protocol (IGMP) snooping. It works like this. When IGMP snooping is turned on, it will send out broadcast communication to judge the members of any multicast group. Using this information, plus the established MAC address table, the managed switch can only send multicast traffic to members of the multicast group. Unmanaged switches treat multicast data and broadcast data in the same way, sending data to each node.

If the network uses manufacturer/user technology or uses multicast communication, then a managed switch is the best choice for value for money.

There are many other reasons to consider using managed switches. Switches of this class usually provide a fault log function that can control the speed of each port, with redundant settings and port mirroring. These additional capabilities can ensure more precise control of network behavior, and can play a very valuable role in troubleshooting. We know that for some nodes on the network, failures cannot be avoided.
