How about the switch? What are the advantages and disadvantages of the switch?
With the development of society, many families have two or several computers. In order to realize the common Internet access of computers, routers and switches are slowly entering people's lives. Routers are certainly not unfamiliar, and the switch everyone knows very well. Less, what about the switch ? What are the advantages and disadvantages of the switch? Let's take a look at the decoration home decoration network Xiaobian.
How about the switch?
1. Advantages and disadvantages of network management type access industrial Ethernet switches:
Advantages of network management access to industrial Ethernet switches:
(1) The backplane has a large bandwidth and the data forwarding speed is faster.
(2) The network management industrial Ethernet switch has flexible networking and applies the access layer of large and medium-sized networks.
(3) The ports provided are flexible, and different interface formats such as SFP, GE, Fast Ethernet interface, and Ethernet interface are selected according to the application of the network .
(4) The network management type industrial Ethernet switch supports the division of vlan. Users can divide the area for different applications and effectively control and manage the network. Progress has curbed the broadcast storm.
(5) The network management type industrial Ethernet switch has large data throughput (throughput ), small packet loss rate (PacketLoss), and low latency (Latency).
(6) Data flow control can be performed based on source, destination, and network segment.
(7) Link aggregation allows IE switches and industrial Ethernet switches and industrial Ethernet switches and servers to be bundled together through multiple Ethernet ports for load balancing.
(8) With the protection function of ARP, the improvement reduces the ARP spoofing of the network.
(9) Binding with a MAC address.
(10) Port mirroring can copy the traffic and status of one port to another port of the switch for supervision.
(11) Support for DHCP.
(12) Access Control List It can control IP packets, such as limiting its traffic, access and providing QoS, and so on.
(13) It has better security performance: Industrial Ethernet switches can perform MAC address filtering, MAC address locking, and can construct a static MAC forwarding table.
(14) Ability to support IEEE 802.1Q and port-based technology-based VLANs. GVRP (GARP, VLAN Registration Protocol) and GMRP (GARP Multicast Registration Protocol) involved in IEEE 802.1Q VLAN are also widely supported.
(15) With SNMP function, it can better manage and control the network.
(16) Easy to expand, flexible application, can be managed by network management software, or remotely accessed through its own access control. Increase the security and controllability of the network.
Disadvantages of network management industrial Ethernet switches:
(1) A little more expensive than an unmanaged industrial Ethernet switch.
(2) Compared with non-network management industrial Ethernet switches, the operation is complicated and needs to be configured.
2. Advantages and disadvantages of non-network management industrial Ethernet switches:
Advantages of unmanaged industrial Ethernet switches:
(1) The price is cheap and the cost is saved.
(2) The number of ports is dense.
(3) User flexibility.
Disadvantages of unmanaged industrial Ethernet switches:
(1) Unmanaged industrial Ethernet switches have limited functions and are suitable for home or small networks.
(2) ARP protection is not supported . The arp attack is not a virus, so almost all anti-virus software has nothing to do with it; but it is better than a virus - because it can cause slow communication, network paralysis, and the loss of information.
(3) The binding of the mac address is not supported .
(4) The division of vlan is not supported . If the end users connected to the unmanaged IE switch are in the same broadcast domain, the broadcast storm will be generated and cannot be protected or suppressed. Congestion, blocking, and flooding of the entire network cause the entire network to collapse.
(5) Traffic-based control is not supported.
(6) The reliability of data transmission is poor, and packet loss is serious.
(7) Single assembly, can not be applied in large and medium-sized networks, and has great limitations on network upgrade and expansion.
(8) Inconvenient management, the hardware failure rate is relatively large.
The above is how the switch brought to you by Xiaobian? What are the advantages and disadvantages of the switch? I believe that everyone has a basic understanding of the switch after reading this article.
