the continuous advancement of technology, half duplex will gradually exit the stage of history. In a broad sense, there are two types of network switches: WAN switches and LAN switches. WAN switches are mainly used in the telecom field to provide basic communication platforms. LAN switches are used in local networks to connect terminal devices, such as PCs and network printers. The transmission media and transmission speed can be divided into Ethernet switches, Fast Ethernet switches, Gigabit E

. LAN interfaces mainly include Ethernet, card ring, Token Bus, FDDI and other network interfaces. Wan interfaces include E1/T1, E3/T3, DS3, and common serial ports that can be switched to X.21DTE/DCE, V.35DTE/DCE, RS232DTE/DCE, RS449DTE/DCE, and EIA530DTE. 2) communication protocol function: This function is used to process communication protocols, including TCP/IP, PPP, X.25, and frame relay. 3) data packet forwarding function: this function is main

. vswitch: a network device that can encapsulate and forward data packets based on MAC (hardware address of the network card) recognition. The switch can "Learn" the MAC address and store it in the internal address table. A temporary exchange path can be created between the initiator of the data frame and the Target receiver so that the data frame can directly access the destination address through the same source address. Switches work at the data link layer of the OSI model, providing Intellig

tunnel) to meet the switch traffic switching requirements with the upper-level trunk. Prevents trunk communication bottlenecks. Common High-Speed ports include: FDDI: The application is earlier and has a wide range. However, there is a cost for protocol conversion. Fast Ethernet/Gigabit Ethernet: easy to connect, low protocol conversion costs, but limited by the network size. ATM: provides high-speed switching ports, but the protocol conversion costs

paths from node 1 to node 2. The data sent from node 1 to node 2 may arrive at different times, but the order is messy. In this case, the combination of the IP router and the ICMP protocol can reduce this problem. The ip mtu is related to the underlying protocol. For example, the Ethernet protocol is 1500 bytes, The FDDI protocol is 4352 bytes, and the frame relay protocol is 1600 bytes. During cross-media transmission, IP addresses can be transmitte

, there are two types of switches: WAN switches and LAN switches. WAN switches are mainly used in the telecom field to provide basic communication platforms. Lan routing switch technology is used in local area networks to connect terminal devices, such as PCs and network printers. The transmission media and transmission speed can be divided into Ethernet switches, Fast Ethernet switches, Gigabit Ethernet switches, FDDI switches, ATM switches, and wild

earlier versions of NFS to read files on the network, the performance of this method will be a thousand miles. of course, if you read files over 10 Mb/s Ethernet or 1 Gbit/s Ethernet, the difference will not be great, but you will also feel the improvements brought about by the adoption of new methods. now, if you have 10 Gbit/s Ethernet, or DDR (dual data rate) IB (InfiniBand), or a faster network in the future, so the existing NFS protocol can make these high-speed networks run like on 1 GB E

way, all routers inside the AS know the routing information to the AS border router. The definition of an AS border router is independent from those of the preceding vrouters. An AS border router can be a vro within a region or a regional border router.

I. data link layer in ATMThe ATM physical layer generally includes the OSI physical layer and the data link layer. features such as the physical media of the OSI physical layer determine the child layer and the transmission collection TC with the same functions as the data link. There are no special physical layer features for ATM. On the contrary, SONET, FDDI, and other transmission systems are used to transport ATM cells. Therefore, we will focus on

(transparent bridging) is a technology that connects local or remote LAN network segments to form a logical subnet. In an environment with multiple LAN segments, the transparent bridge) network device can filter LAN frames, only transmit frames to the destination CIDR block rather than to other CIDR blocks. It checks the source MACMedia Access Control address of each LAN frame to determine the network segment of the device that sends the frame and remembers it. Later, bridge) transmits the fram

, and the LLC layer is the same. One of the main functions of the data link layer is to encapsulate and identify upper-layer data, which is implemented by the LLC sublayer in the LAN. 802.2 defines the LLC sub-layer, which is shared by the 802 series standard. Another major function of the data link layer is to adapt to a variety of transmission media and process channel occupation, site identification, and addressing issues on any specific media. In the LAN, this function is implemented by the
