fddi switch

I. The component of FDDI Figure 1 As you can see from Figure 1, the components that make up FDDI should have at least the following parts: 1, fiber optic cable. 2, FDDI adapter. 3, FDDI adapter and fiber-connected connectors. However, in order to make the network have strong adaptability, and can be as backbone o

Optical Fiber Distributed Data Interface (FDDI) is one of the highest transmission rates in the current mature LAN technology. This transmission rate up to 100MB/S network technology is based on the standard is ansix3t9.5. The network has the characteristics of timing token protocol, supports a variety of topologies, and transmits media as optical fiber. Using fiber as a transport medium has several advantages: 1, a longer transmission distance, the

(Fddi:fiber distributed Data Interface) Optical Fiber Distributed Data Interface (FDDI) is a set of protocols that are developed by the United States National Standardization Organization (ANSI) to send digital signals on optical cables. FDDI uses a dual-loop token, with a transmission rate of up to 100Mbps. Because of its support for high-bandwidth and long-distance communication networks,

In FDDI reverse double loop or other structure, the data unit transmitted on the fiber is called the media access Control (MAC) frame. As shown in Figure 11.

I'm going to go down to the two and three layers of the switch. A two-tier switch is equivalent to dividing an interface into multiple interfaces, just to provide a lot of interfaces; (if the landlord is not a professional person can ignore the following content) theoretically it can be understood that the switch does not split the broadcast domain, but split the

Switch type (rack style, fixed-profile with/without expansion slots The rack switch is a slot-type switch that is scalable and supports different network types, such as Ethernet, Fast Ethernet, Gigabit Ethernet, ATM, Token Ring, and FDDI, but the price is more expensive. A fixed-profile band-slot

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.csdn.net/herostarone/article/details/8256235 Two

, at least five cat-5e lines should be used, and six cat-5e lines should be used to ensure stability and high speed. 2. SC Optical Fiber Interface The SC optical fiber interface has been applied in the 100Base-TX Ethernet era. Therefore, 100Base-FXF is the abbreviation of the fiber word fiber, therefore, it is not widely used. Now the industry is vigorously promoting Gigabit Networks, while SC Fiber interfaces are gaining greater attention. Many types of fiber interface, SC Fiber Interface is ma

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 with corresponding ports in one of their own. Address table. The specific work flow is as follows: (1) When the switch receives a packet from a port, it first reads the source MAC a

An instance of VLAN configuration for Cisco L3 switches and L2 SwitchesCisco VLAN implementation is usually port-centric. The port connected to the node determines the VLAN in which it resides. There are two ways to allocate a port to a VLAN: Static and Dynamic. The process of creating a static VLAN is to forcibly allocate the port to a VLAN. That is, we first create a VLAN on The VTP (VLAN Trunking Protocol) server, and then assign each port to the corresponding VLAN. This is the most common me

SC Optical Fiber InterfaceThe SC optical fiber interface has been applied in the 100Base-TX Ethernet era. Therefore, it was called 100Base-FX (F is short for fiber ), however, at that time, because the performance was not better than that of twisted pair wires, but the cost was relatively high, i

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 router. Major differences between a wireless switch
