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 fi
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
(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.

data link layer (ddl) of two local networks.The bridge is designed to store and forward data in various LAN networks. It is transparent to End Node users. When the end node transmits packets through the bridge, it does not know the existence of the bridge. A bridge can connect the same or different LAN networks to form an extended LAN. I. Working Principle of Bridges To illustrate the working principle of the bridge, we will describe it in the context of fd

To understand Ethereum Privatenetwork first to understand the two official Ethereum network, now Ethereum officially provides two kinds of network: Production Environment Network Test network Testnet The following is a brief explanation of the two types of networks. Ethereum Production
://anheng.com.cn/news/24/586.html The second type is the key words for determining the transmission direction, including SRC, DST, DST or SRC, DST and SRC, which indicate the transmission direction. For example, Src 210.27.48.2 indicates that the source address in the IP package is 210.27.48.2, and DST net 202.0.0.0 indicates that the destination network address is 202.0.0.0. If no direction keyword is specified, the SRC or DST keyword is use
direction. For example, src 210.27.48.2 indicates that the source address in the IP package is 210.27.48.2, and dst net 202.0.0.0 indicates that the destination network address is 202.0.0.0. If no direction keyword is specified, the src or dst keyword is used by default. The third type is the protocol keyword, which mainly includes fddi, ip, arp, rarp, tcp, udp, and other types.

bridges or routers.3) Change the shared media mode to swap mode. A virtual local area network (VLAN) appears on the basis of a switched LAN.Four, Man TechnologyThe IEEE802 Commission's definition of man is based on a summary of the characteristics of FDDI technology, which is generated relative to the WAN and LAN. The early man was the optical fiber as the transmission medium, the preferred technology is t
Network Programming (1) -- easy understanding of network resource positioning and Network Programming Network Resources It sounds very difficult to learn network programming at the beginning. At that time, if you followed the correct method and understood more, it would be e
segments to adjust the bandwidth to reduce the bottleneck of information flow between the LAN. Now there are Ethernet, fast Ethernet, FDDI and ATM exchange products. Similar to traditional bridges, vswitches provide many network interconnection functions. Vswitches can economically divide networks into small conflicting domains to provide higher bandwidth for each workstation. Protocol transparency allows
210.27. 48.2, dst net 202.0.0.0 indicates that the destination network address is 202.0.0.0. If no direction keyword is specified The default value is the src or dst keyword. The third type is the protocol keyword, which mainly includes fddi, ip, arp, rarp, tcp, udp, and other types. Fddi indicates that The specific network
