Over the past few months, discussions have become increasingly enthusiastic about the evolution and deployment of 802.11ac. However, in consumer and enterprise-level markets, users' enthusiasm is not the same. 802.11ac has been widely supported in the consumer electronics industry. Apple, Samsung, HTC, Xiaomi, and many other mobile phone manufacturers have joined the ranks of 5G WiFi. However, for enterprise-level products, the promotion of 802.11ac seems to be slow. However, with the user's dem

in front of the Libpcap capture packet, especially in the gigabit network conditions, a large number of drops, online search for a long time, probably all Pf_packet +mmap,napi,pf_ring and other methods, I pf_ring+libpcap experiment, The detection of gigabit network conditions, capturing the performance of the packet is very good, almost no packet loss, the experimental environment with the following process

Scale, chain, the development of a diversified concept and the continuous upgrading of hardware equipment, the core router equipment is the center of Internet cafes, internet cafes multi-Wan intelligent routers for a wide range of broadband access to the Internet café provides a side, the choice of internet cafes Gigabit WAN Smart Router is also necessary, for the following reasons. 1, the Internet bar bandwidth needs more, the need for large bandwid

What are the advantages of a small pluggable (SFP) port for a Gigabit Ethernet switch? How do I connect the four SFP ports of a d-link DGS 1248 t smart switch? I think the main advantage of the SFP port is the flexibility to connect to the network. The SFP port is a hot-swappable input/output device that can be plugged into a Gigabit Ethernet port or slot to connect the port to the network. SFP ports can

Previously, we talked about libpcap packet capture, especially in the case of a gigabit network, which results in a large number of packet loss and a long time of searching on the Internet. This is probably a method like PF_PACKET + MMAP, NAPI, and PF_RING, I tested PF_RING + libpcap and found that the packet capture performance was good under gigabit network conditions, with almost no packet loss. The foll

As we all know, Ethernet technology is closely related to Cabling Technology. How can we develop the Gigabit Ethernet technology to support the next generation of cables, especially the six types of cables in the protocol?■ Do I need six types of cabling for a gigabit network?Currently, there is a lot of debate over whether cat6 cabling is required in the cabling industry. Remember that when three types of

Recently, Huawei 3Com has launched Quidwayreg in response to the increasing number of Network Terminal Services and the increasing demands for forwarding performance, security and reliability, and smart management of edge network devices; s3100 series Gigabit smart network-managed Ethernet switches.Quidwayreg; S3100 series Gigabit smart Ethernet switches use Huawei 3Com universal VRP universal routing platf

As a key school in Jiangxi Province, Cangnan Middle School was listed as a pilot school in the province by the Ministry of Education of Jiangxi Province, and planned to promote the network application of the school gradually to the whole province. The new campus, an area of more than 20,000 square meters. Cangnan Middle School Initial Network application basic requirements are able to meet the campus network large capacity, high-speed data transmission. In contact with the full network, fully to

As we all know, Ethernet technology is closely related to cabling technology, so how does gigabit Ethernet technology develop to support a new generation of cables, especially the six types of cable in the protocol? 　　 Gigabit network need six kinds of wiring? Wiring industry at present the need for six types of wiring is a lot of controversy, remember when the 1992 three types of wiring is prevalent, and

announce the time to integrate it into Windows. Chip manufacturers Alacritech and Broadcom also announced that a new Ethernet controller will be released in future Windows systems. Chip manufacturers develop TCP/IP Offload functions in dedicated chips, which will greatly threaten the fate of dedicated chips that can be connected by inserting multiple Gigabit NICs on the server. However, chip manufacturers must develop at a relatively high level witho

wireless transmission. The built-in powerful SPI firewall can protect PCs from intruders and most known Internet attacks, VPN penetration is also supported. At the same time, LinksysWRT320N starts from the user experience and works with the gorgeous and easy-to-use "Lela" software, which enables users to establish a wireless network within a few minutes, making applications and management very convenient. Elegant Design of WRT320N CISCO launched the dual-band 802.11n wireless router WRT320N. Th

Under the KVM can generate two types of network cards, RTL8139 and E1000, in fact, should be the underlying generation of different chips of the network card, and not with the host network card is what model is what model, wherein the default is 100 Gigabit network card, that is, RTL8319 crab card, the other is the E1000 Gigabit network card.Setup steps:1.

Last year, I started a Seagate Central. There is no time to study, direct plug on the use. Intranet speed has been maintained around 10m-15m. This year 618 changed the gigabit router, the speed of the instant upgrade to the 50m-70m. Cable used are five categories, the heart of the question: if replaced by Super Five class line or six class line, performance can not be improved point?? So on-line search a friend very professional answer, can't help sti

ports affect the forwarding rate of non-congested ports. During the test, port A and port B are used to send data to port C to form A congested port, while port A also sends data to Port D to form A non-congested port. The result shows the number of received frames, the number of collision frames, and the frame drop rate.8. Full mesh This test is used to determine the total number of frames that the switch can process when all its ports receive data. Each port of the vswitch sends frames to all
