There are many things worth learning about Ethernet switches. Here we mainly introduce the Ethernet switch purchasing techniques and principles. Currently, Ethernet switches use three packet exchange modes: pass-through, storage-forward, and fragment isolation when transmitting data packets from the source and destination ports. 1. pass-through switching An

Many enterprises now have their own Metro Ethernet services. Here we will give you an analysis of the coexistence of Metro Ethernet and traditional WAN services, South Korea's Enterprise Networks Company (formerly GNG Networks) an Optical Transport MAN (MAN) is being built along the subway lines in six major South Korean cities (including Seoul) and plans to provide Metro

At present, most commonly used Ethernet Media are cables, supplemented by optical cables. Generally, 10 BASE-T Ethernet requires only three types of links. 100Base-T Ethernet requires five types of links to ensure its operation. In addition, a considerable number of five types of links can support BASE-TX applications, the cat5e chain can stably support 1000Base-

With the development of China's exchange industry, it also promotes the upgrade of various exchange technologies. Here we analyze the specific functions of various main parameters in the Ethernet switch. Generally, fixed configuration switches with no expansion slot support only one type of network. Rack-mounted Ethernet switches and fixed configuration switches with expansion slots support more than one ty

From the data, we can see that the bandwidth of the Ethernet switch stack is dozens of times the speed of the switch port, which can effectively improve the network performance, when the number of ports that a single switch can provide is insufficient to meet the requirements of the network computer, more than two switches must provide the corresponding number of ports, which also involves the connection between switches. Basically, there are two ways

How can network managers implement bandwidth-intensive applications on local area networks (LANs) when budgets are tight and must maintain existing network systems? The latest Ethernet technology, 1000BASE-T (Gigabit Ethernet on the five-type twisted pair) can help network administrators quickly improve the performance of your network in a simple and inexpensive way.1000BASE-T is an

In September 1997, the ISO/IEC JTC1 SC25 WG3 Standards Committee decided to develop two new types of cables for the next version of ISO 11801, the two new types of cables are divided into six categories/Class E and seven categories/Class F according to their performance. The decision aroused great interest in the cabling industry and some standards committees (especially the American organization TIA/EIA and the European CENELEC.In addition to the work carried out by the Cabling Standards Board,

Rack-mounted switch, fixed configuration with/without expansion slot) rack-mounted switch is a slot type switch, which has good scalability and supports different network types, such as Ethernet, fast Ethernet, Gigabit Ethernet, ATM, licensing ring, and FDDI, but the price is relatively high. A fixed-configuration vswitch with expansion slot is a type of switch w

calculation. For Gigabit Ethernet, the calculation is as follows: 1,000,000,000bps/8bit/(64+8+12) Byte=1,488,095pps Description: When the Ethernet frame is 64byte, it is necessary to consider the fixed overhead of the 8byte frame head and the 12byte frame gap. Therefore, a wire-speed Gigabit Ethernet port in the forwarding 64byte packet packet forwarding rate is

Layer-3 Ethernet switches are quite common, so I have studied the problems related to the CPU packet sending and receiving of layer-3 Ethernet switches. I would like to share them with you here, hoping they will be useful to you. Layer-3 Ethernet switches are developing rapidly. On the one hand, bandwidth and switching capacity of network devices are greatly incr

Note the following when setting the duplex mode and speed of an Ethernet Port: Considerations for setting port duplex mode Considerations for setting port Type Duplex status The Mbps Ethernet electrical port can work in full, half, or auto mode and can be set as needed; The Gigabit Ethernet electrical port can work in full, half, or auto mode. However, when the s

SummaryThis article introduces the principle and basic implementation process of VoIP, and analyzes the composition of audio latency in the Ethernet environment. The experimental results show that the audio latency in the Ethernet environment is mainly composed of the buffer latency and API call latency, and the most important part is the API call latency. This paper proposes a method to reduce API call lat

Ethernet is a local area network technology developed in the the 1980s, because of its easy to use, low price and high speed, it soon became the mainstream of LAN. With the advent of Gigabit Ethernet (GbE) and the emergence of Gigabit Ethernet (10GbE), as well as the low cost of direct architecture of GbE and 10GbE technology in optical fiber,
