The relationship between the ether Square and the block chain From the history of the Block chain, the first bir

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,

The ethernet switch technology has become more mature and stable. Because the Ethernet switches in the industry share many similarities with the switches we usually use, the design of the Industrial Ethernet switch also uses the principle of the commercial switch. With the rapid development of Ethernet technology and i
