This article briefly introduces the composition of a layer-3 Switching Network and the responsibilities of each layer. Cisco layer-3 switch is a typical layer-

. According to the survey data, this is not necessarily true. The cost of using CAM for route table search is not high. Take KawasakiLSI's CAM chip KE5BLME064 that supports longest matching search as an example. It supports 64 K route prefix items. Each ENTRY40bit is wide and the packet search speed can reach 6.7 Mpps, with a latency of several hundred nanoseconds, the price is less than 60 USD 6. Of course, reducing the supported route table items will undoubtedly reduce the cost, and there is

know that in order to cope with the increasing data traffic, shared media networks have been replaced by switching networks. This change has a direct impact on the traditional routers used for network segmentation. In view of the large traffic that spans the IP address or IPX subnet, the router has actually become the bottleneck of network transmission. The reason is that traditional routers focus more on multiple media types and transmission speeds. Currently, data buffering and conversion cap

, normal switches cannot effectively isolate data transmission between sites in the network and control users' access permissions, which threatens the security of users' LAN. A layer-3 Switch provides a policy-based security access mechanism through a variety of explicit or implicit VLAN division methods, improving network security and effectively inhibiting the generation of broadcast storms. With the rap

L2 chip, the second-Layer Chip forwards the packet. Because low-cost CPU processing is slow, the processing speed of such a layer-3 switch is slow. Market product selection　 In recent years, the construction of Broadband IP networks has become a hot topic. Next we will introduce some layer-

, as the core of the network, there is no substantial breakthrough in the router technology that acts as the interconnection between networks. Therefore, a new routing technology came into being-layer-3 switching technology, which is a routing technology because it works on the layer-3 network protocol, the two-

The rapid development of computer network technology and application has promoted the continuous improvement of the degree of social informatization, while the improvement of information demand has promoted the emergence of new network technologies. These technologies have greatly improved network scalability, flexibility, transparency, and speed. Among the numerous network products, switches play a vital role in building high-performance networks, and their technological development is also rem

Three-tier switching has been widely used since its concept was proposed. Although it has only been a few years, multiple access ports and low prices provide a perfect solution for small network users, otherwise, it would take a second step, so that layer-3 switches are also interconnected over the Internet. In today's network construction, layer-

switches, proposed many different solutions, and launched many products. Such as Cisco TAGSwiching, Ipsilon, Toshiba's cell Switch Router CSR: CellSwitchingRouter, and IBM's ARISAggregateRoutebasedIPSwitching ), and the Multi-Protocol Label Switching MPLS: Multi-ProtocolLabelSwitching of IETF. TAGSwitching is a vro at the edge of the switch. It maps the layer-3

of G.703-ETH bridge converter for access, the price is equivalent to G/V converter, therefore, with the new network access solution, the larger the scale, the more nodes that are connected to the downlink, the more cost savings. When the center end of the uplink uses a layer-3 Switch for access, the downlink branch node does not need any grade router, only need to be equipped with a hub or switch and G.703

effectively inhibiting the generation of broadcast storms. With the rapid development of China's enterprise network, campus network and broadband construction, the application of layer-3 switches has penetrated from the initial backbone layer and convergence layer to the edge access

one undertaken by the traditional router, but a wide variety of broadband access devices, such as broadband routers and VPN firewalls. Three-layer switches that use VLAN routing instead of traditional routers have emerged. hardware-based route forwarding is more efficient and faster than software-based route forwarding of traditional routers. Now enterprises have a better choice to deploy VLANs, that is, layer
