Ethernet switches are an essential part of network transmission, and managed switches have many features for supporting complicated network applications.
FREMONT, CA: In recent years, ethernet switch applications have grown in popularity and have become an increasingly important technical means of increasing the economic interests of corporate enterprises by achieving better quality, greater productivity, and reducing energy consumption of these enterprises. Switches provide dedicated paths for transmitting telecom signals between any two network nodes connected to a switch. Ethernet switches are the most common type of switch, but there are also voice switches for telephones and optical fiber switches.
In the network technology system, the invention of switching technologies has significantly improved the computer transmission efficiency compared to the previous mode of working in which computers used a common hub.
Features of managed switches
The network-managed switches come with various remote management methods, including terminal control ports, web interfaces, network management software, and Telnet programs that allow users to access the switches remotely. A wide variety of network management functions can be performed by these devices, including monitoring switch ports, setting up VLANs, and managing trunk ports. The background network management feature allows local or remote real-time monitoring of the status of the switches and the network operation conditions, thus giving a comprehensive overview of the working status and the working modes of the switch ports in real-time.
The advantage of network-managed switches over ordinary switches is that they feature multiple network management functions, such as VLANs, CLIs, SNMPs, IP routings, QoSs, etc. They have more advantages in application scenarios than ordinary switches.
Supports complex network applications: Video conferences and IP phone calls, for example, benefit from network-managed switches as they provide comprehensive QoS support. An ordinary switch network cannot cater to multimedia or special networking applications; any data has to queue before transmission.
Improved network stability: A network-managed switch can link redundancy while doubling the bandwidth between devices through spanning tree and EtherChannel technologies, balancing network load and maintaining stability. Ring topologies result in a paralyzed network if switches have redundant configurations.
Enhanced network security: It is more secure for data storage and safe visits when network managed switches have network security features than ordinary switches without; using VLAN, Private VLAN (PVLAN), and Access Control List (ACL), they can isolate different departments' networks, preventing specific users from accessing sensitive information.
Improved network transmission efficiency: The transmission efficiency will be severely affected when there are enough computers and communication protocols in the network. There shall be no more than 150 computers on a single network structure. Ordinary switches cannot differentiate broadcast areas. In contrast, VLAN-enabled switches can divide a network into several logical subnets, thereby minimizing the broadcasting range and increasing the network's transmission efficiency.
Supports remote monitoring and management: Monitoring, laying out, and managing switches remotely is equally important for medium to large networks. An IP bit address can enable all of these functions on network-managed switches. Using a computer, a network manager can manage all switches in the network, monitor their status, and modify switch allocations according to needs. The complexity and intensity of managing a network are effectively reduced with network-managed switches. Network management software allows centralized management but can also stack several switches for single management.
