Cisco has launched the CiscoMDS9100 series of multi-layer Intelligent Optical Fiber switches. To meet the SAN needs of small and medium-sized enterprises, the Intelligent Optical Fiber switches are large devices, mainly to ensure data forwarding at a higher speed and accessibility.
It can also achieve seamless migration from a small SAN to a large-scale SAN, effectively protecting customers' SAN infrastruct
Switch switches in place, replacing the original hub hubs.
First, let's start with a simple understanding of the differences between switches and hubs. The hub uses the shared bandwidth of the work, simple for example, the hub is like a one-way street, "10M" bandwidth is used in multiple ports, when a port occupies most of the bandwidth, the other port will appear very slow. Instead, the switch is a unique
Vswitches can be divided into backbone switches and desktop switches based on different application scenarios. backbone switches are mainly used for enterprises to build backbone networks, while desktop switches are designed to directly connect to computers, there is a big difference between the two.Backbone switchBack
Next we will study the advantages of all-optical switches. They can easily expand to the interconnection, grid-like and ring-like hybrid networks, and grid-shaped networks, which cannot be achieved by some common switches. At present, operators are keen to adopt a new smart optical network based on the new generation of optical devices.
A typical example is an all-optical switching device. All-optical
Disadvantages of non-NMS switches: 1. Non-NMS switches have limited functions and are suitable for household or small-sized networks. 2. ARP protection is not supported. ARP attacks are not a virus, so almost all anti-virus software is helpless. But they are more like viruses-because they can cause slow communication, network paralysis, and information leakage. 3. MAC Address binding is not supported.

As an indispensable device in networking, core switches are gradually improving their functions to meet more user needs. The simplest LAN is usually composed of a hub (or switch) and several computers. As the number of computers increases and the network size expands, in more and more LAN environments, core switches replace hubs, and multiple switches replace sin
numbers over port 1024. You can find the latest list of allocated port Numbers on RFc1700 "Assigned Numbers. The additional information provided by the TCP/UDP port number can be used by the network switch, which is the basis for layer-3 switching.
With the development of the communication industry and the advancement of information technology in the national economy, the Ethernet switch market has steadily increased. Ethernet features high performance, high flexibility, relatively simple, and
On seeing this topic, perhaps readers are dismissive: What are the networking options for the switch? It's all about connecting it to the user's computer. Of course, that is for switches in the entire network location, some high-level switches such as three-tier exchange, network management-type products, in the networking structure is not so simple.
Learn about the fresh features of the switch

Asymmetric switches are still commonly used. So I have studied the working principle and network performance of asymmetric switches. I would like to share with you here, hoping to help you. For enterprises with tight pockets, using asymmetric switches to improve network performance is a good choice. For example, asymmetric sw
LAN switches are the "cornerstone" for building network platforms. LAN switches require less configuration, less space, less wiring, cheaper prices, and provide higher and more reliable performance, enterprise-level switches are both rack-mounted and department-level switches can be rack-mounted.
For example, we have s
At present, there are two ways to increase the density of the switch port in the local area network : One is to use the chassis switch, support multiple module slots, by adding modules, you can meet different port density requirements; the other is to stack the switches with a tiered switch, And through a single IP address, the entire tiered switch for integrated management, the general number of stacks is 2~4.
The same feature of a scalable switch a
With the development of the communication industry and the advancement of information technology in the national economy, the Ethernet switch market has steadily increased. Ethernet features high performance, high flexibility, relatively simple, and easy to implement. Therefore, Ethernet technology has become the most important LAN networking technology today, and Ethernet switches have become the most popular swi
With the development of the routing industry, the application of the routing switch technology is also more extensive, and its role is more prominent. Here we will mainly introduce the technology and practical application of the routing switch. The routing switch technology is the "cornerstone" for building a network platform, also known as the network switch. It is also a type of hub, but it is quite different from common hub functions.
A general hub only serves to receive and send data, while
A backbone switch can establish multiple nodes at the same time through a switch, but it does not affect the communication capability between each node, port switching is used to allocate and balance Ethernet module ports among multiple network segments on the backend.
With the development of the communication industry and the informatization of the national economy, the backbone switch market has steadily increased. Ethernet features high performance, high flexibility, relatively simple, and ea
