-effectiveness of equipment should be fully considered to achieve the maximum ROI. 2. Upgrade the switch Vswitches in an enterprise network are divided into three layers: Core-layer switches, aggregation-layer backbone switches, and access-layer workgroup switches ). As the hub of the entire network, almost 80% of network transmission is completed by the core switch. Therefore, the performance of the core switch determines the performance of the entire network. Therefore, when upgrading the netw

Therefore, the performance of the core switch determines the performance of the entire network. Therefore, when upgrading the network, you should first consider upgrading the core switch. 3. upgrade from 1g to 1G network To upgrade a Gigabit Ethernet, you must first upgrade the network b

The network backbone uses network-managed fiber and copper Gigabit Ethernet technology to form a high-speed link channel. A second-level aggregation switch is a two-layer Gigabit Switch with network management capabilities. In the West network center on the South 3

With the development of network technology, gigabit to the desktop has become a fact, six of the wiring has been more and more users of widespread concern. However, in the current market, people have a lot of different understanding of the installation of six kinds of wiring. Many manufacturers to gain market share, wishful thinking ground to all projects to promote six types of wiring, but not fully consider for the end user to provide a reasonable

Generally, the calculation method is as follows: 1) wire speed backboard bandwidth Measure the test taker's knowledge about the total bandwidth provided by all ports on the vswitch. The formula is as follows: number of ports * corresponding port rate * 2 (full duplex mode). If the total bandwidth is less than or equal to the nominal backboard bandwidth, the bandwidth is linear. 2) Layer 2 packet forwarding speed Layer 2 packet forwarding rate = number of Gig
