different switches

layer-3 switching solution is a solution that supports dynamic integration at all levels of classification. Although such multi-layer dynamic integration can also be completed by a traditional router and a layer-2 switch, however, compared with the third-tier switch, this scheme requires more device configurations, larger space, more wiring, and higher costs, in addition, the data transmission performance is much worse, because in massive data transmission, the routers in the solution cannot ov

brewing in the process of changes, as shown in the following aspects. Low-end switch: required control function The peak of broadband network construction was once high, but it soon revealed that due to the imperfect existing technologies and equipment functions, the bandwidth network profit model was single and could not meet the needs of users at multiple levels and the price bearing capacity. To improve the profitability of a broadband network, the operation and management of the network are

activity. Note that the connected port and open port State not only mean that the cable is connected, but also indicate that the physical layer and the MAC layer are active. 1. None connected 2. None of the active (connected and open) 3 activity 0% 4 activity 50% 5 activity 100% 4. Frame/packet size This is critical. Historically, two-layer and three-layer switches are tested through a series of frames/data packets of

switch, however, compared with the third-tier switch, this scheme requires more device configurations, larger space, more wiring, and higher costs, in addition, the data transmission performance is much worse, because in massive data transmission, the routers in the solution cannot overcome the transmission rate bottleneck. Ii. Advantages of layer-3 switches When talking with some friends, I often hear something similar to "Will a layer-3 Switch rep

Routers Layer 2 exchange technology works at the data link layer. It forwards the MAC address of the received packet to the corresponding port in the internal address table, and records the MAC address and corresponding port of the packet in the internal address table, if the MAC address is not in the table, broadcast and wait for a response. Therefore, L2 switches have the MAC address learning function, which is transparent to the network layer or h

improving performance, this investment is worthwhile. After deploying smart switches, all the network congestion problems that previously plagued the system have been solved? Although smart switches can classify traffic at the edge of the network to give different priority levels and limit broadcast traffic, smart switches
