switched ethernet vs dedicated ethernet

ATM, POS and other WAN interface in order to meet the needs of the metropolitan area network. , and the high-end routers have borrowed more from the technology of routing switch, the hardware is used for routing calculation, and the forwarding ability is greatly improved. Switches and routers tend to converge at the high-end, and similar devices from different vendors may be referred to as "routing switches" or "switched routers." It is also the mat

connections, and the three-tier switch is used in the LAN core to replace the previous routers to achieve cross VLAN access. With the development of routing and switching technology, the three-layer switch is gradually developing to multi-layer exchange, such as TCP ports and DiffServ parameters above the 4th layer, which are processed by hardware. And the support of the routing protocol is extended by the initial RIP to the OSPF and even WAN Network routing protocol BGP of the large-scale netw

TFTP server, or download the previous configuration files of the Gigabit Ethernet switch from the TFTP server. If errors occur in the configuration, these two items are useful to engineers. In the 3Com4900 Gigabit Ethernet switch, every time you change the settings, 3Com 4900 automatically saves the settings, which is faster than other manufacturers' dedicated s

Access Technology Ethernet access usually uses two-layer Ethernet switch, it works on the data link layer, providing data flow control, transmission error processing, transmission media access control functions. It can connect multiple LAN segments to form a larger LAN. Ethernet switch can set up a number of different point-to-point

departments or floors of an enterprise. Of course, these Ethernet switches must have excellent performance. At the same time, due to the direct connection to users, remote management requirements are also very high for functional features such as VLAN and address filtering. 10G Ethernet switch: Communication Between TCP/IP and Telecommunication Network With the increasing popularity of Gigabit

. There is no voltage matching problem. The I/O pin of 3.3 V is generally 1.8 V, but the clock input foot is an exception. It can only withstand the input voltage of V/1.9V, the 1.8 V/1.9V active crystal oscillator is rarely sold on the market, so passive crystal oscillator is used. ③ Reset Circuit Design The system has two chips that need to be reset: DSP chip and Ethernet Control Chip Ax88796. However, the two have different requirements for Reset s

It is not a specific network, but a technical specification. Ethernet is the most common communication protocol standard used by local area networks. This standard defines the cable type and signal processing method used in LAN. Ethernet is 10 ~ 10 Base T Ethernet is the most widely used Ethernet technology because of

coverage limit. Compared with the half-duplex mode, the MAC layer of the full-duplex Gigabit Ethernet switch has the following differences:◆ Frame sending during the reception activity will not be postponed◆ Conflicting indication in full duplex mode will be ignored◆ No carrier extension, the minimum frame length is still 64 bytes◆ No frame burst In full-duplex switched

-network components have very high reliability and flexibility. These optical Ethernet components, which can be applied to both public and enterprise networks, can meet the key high value-added services such as packet voice and networked storage of operators, and can satisfy many types of enterprise networks.At present, optical Ethernet solutions have been listed, and achieved a series of brilliant performa

LayerDatagrams (IP packets) are passed to the data link layer, and the PDU that encapsulates the data link layer header is called FRAME (data frame) and is shown as an Ethernet frame. Finally, the frame is converted to bits and transmitted over the network media. This protocol stack passes the data down by layer, and the process of adding a header and a trailer is called encapsulation. Second, the data formatIt is important to note that the
