Simply put: Layer-1 switchOnly physical layer protocols are supported (one phone-controlled switch can be called ???)L2 SwitchSupports physical layer and data link layer protocols, such as Ethernet switches.L3 SwitchSupports physical
transmission and commerce far exceeds the improvement of computer processing power. Offloading content to a web switch balances the entire site's infrastructure.
------------------Layer 3 switch is to lead the switch by feature!!
Today, the tutor told me about the company's network topology, related to the switch, the basic concept of routers and principles, I am not very clear, so on the internet to learn the information to learn a bit, and then feel that this article is good, so it reproduced, but I reproduced not the original text, and did not attach the original link.
Here I posted a link to my reprinted article: http://blog.csd
Often see network friends in the difference between the switch and router, in fact, if you have used both switch and router friends should know, for everyone, switch and router use the biggest difference is that the router can rea
network members. In order to facilitate the user to operate and have a rich indication function, omni-directional QS-508 can visually and clearly display the network operating conditions. And with 10/100m self-learning, adaptive function, "silly" to let users no longer need for complex network application environment injury fine trouble, all the settings by the switch themselves.
The difference between a
Two-layer switching technology is a mature development, two-layer switch is a data link layer device, can identify the Mac in the packet
Address information, forwarding based on MAC addresses, and recording these MAC addresses wit
can provide high-speed connection ports that support fast Ethernet or FDDI. These ports are used to connect other vswitches in the network or provide additional bandwidth for key servers with high bandwidth usage. It is a network device and has a part of the router function. It can decide where the received data is sent, and its speed is faster than that of the
With the popularization of the Internet, the development of information technology, data center construction needs and standards are also constantly developing, so the data Center for network equipment requirements are gradually upgraded, ordinary switches are often unable to meet the needs of the data center.
Compared with common switches, data center switches need to have the features of high capacity, large cache, virtualization, FCOE, two-layer t
In recent years, with the rapid development of Internet/Intranet and the wide application of the B/S computing model, the cross-region and cross-network business has experienced a sharp increase. The industry and users are deeply aware of the bottleneck effect of traditional routers in the network. A layer-3 switch can operate on the
their mutual connections may vary depending on the environment, the routing information is usually updated as specified in the Routing information protocol used.
Main difference: The two-tier switch works at the data link layer, the three-tier switch works at the network
Two-tier switch:The second layer switching technology is more mature, two layer switch is a data link layer device, can identify the MAC address information in the packet, according to the MAC address to forward, and these MAC add
in detail the differences between switches and hubs through theories and instances. To sum up, this article fully discusses the differences between vswitches and hubs from the outside to the inside, from the surface to the essence.
In today's global network era, networks have become essential for human life. As an important device for LAN Construction: switches and hubs play a "pivot" for LAN data transmission. So what
Often have friends to consult the most fire software station small series, about the difference between switches and routers, in fact, if you have used the switch and router friends should be aware of, for everyone, switches and routers in the use of the biggest difference is that the router can achieve dial-up Interne
sharing, link backup and other network routing information exchange and so on routers have the function. In order to connect with various types of network, the router interface type is very rich, and the layer three switch is generally only the same type of LAN interface, very simple.
Recently I saw an article about anti-L3ArticleWhen my hands itch, I will sacrifice some time to discuss this old topic.
1. What is Layer 3?
Many people love to confuse the three-layer architecture with MVC, but we can consider their differences from the simplest perspe
