head. In order to ensure that the network can be stable in the gigabit state of operation, physical wiring needs to achieve what kind of performance, what kind of acceptance can be guaranteed? End-to-end Network device communication links are defined as channels (Channel) in the standard, one channel link contains a horizontal link, 2 user jumpers, when the horizontal link with the permanent link "Perm." Link "model, jumper using the jumper monomer" Patch cord "model test and meet the require

material, only a layer of insulating rubber package, the price is relatively cheap a lot, but also can make their own, the advantages are no shielding housings, light weight, easy to bend, good flame-retardant effect. In addition to the electromagnetic radiation severity, high transmission quality requirements such as the use of STP in the wiring, in general, we are using UTP. UTP Twisted pair is also graded, the existing UTP can be divided into three categories, four categories, five categori

network line is five lines, CAT6 logo on behalf of the network line is six lines; if there is no sign of the network cable, we should be vigilant to find ways to create conditions, To test and identify the network cable according to the above method. 　　5, test the distance of the wire It is known that the common twisted pair is connected by four groups of intertwined cables. The so-called wire is the distance between the cable is actually the lengt

How about Kirin 928 processor? The following will be the Kirin 928 processor performance evaluation, Huawei Glory 6 Extreme version of the processor is Kirin 928, then its performance? You can learn through the following. From Huawei's official release, Kirin 928 is currently the fastest HiSilicon processor, the frequency reached 2GHz, is still a 28n process, support 300Mbps LTE Cat6. In addition, Kirin 928 of the processor on the GPU is stil

The SATA Express interface of the ASUS Z97 Motherboard is currently useless, but with the development of the computer interface, it is likely to occupy a niche.1, as the name implies, Sata-express is the SATA interface + pci-express Hybrid, the theoretical bandwidth of up to 10Gbps, 4Gbps higher than SATA3.0, it can be compatible with SATA standard HDD, can also use sata-express interface high-speed SSD, each sata-express interface can connect 1 sata-

haproxy also run well, stability can be comparable with LVS;Second, according to official documents, HAProxy can run full 10gbps-new benchmark of HAProxy at ten Gbps using myricom ' s 10GbE NICs (myri-10g pci-express), this as a software-level load Balanced, is also more amazing;Third, Haproxy can be used as MySQL, mail or other non-web load balancer, we often use it as MySQL (read) load balancing;Four, with a powerful monitoring server status of the

One, the classification of the computer networkThe computer network can be divided into three types of local area network (LAN), Metro (man) and wide area networks (WAN) according to its geographical coverage.The technical characteristics of 1,lan are mainly shown in:1) LAN covers a limited geographical range, it adapts to institutions, campuses, factories and other limited range of computers, terminals and all kinds of information processing equipment network needs.2) LAN provides high data tra

, Nic should be able to handle the total throughput of the OSD hard disk, so recommend a minimum of two gigabit network cards, respectively, for public network and Cluster_network. A clustered network (preferably not connected to the Internet) is used to handle the additional load generated by data replication and helps prevent denial of service * * *, which interferes with the data co-locating group so that it cannot return to the Active+clean state when the OSD data is copied.

the 28,000 MHz (GHz) band, compared to the current fourth generation long-term evolution (4G LTE) service with a rate of only 75Mbps. The previous transmission bottleneck was widely considered a technical problem in the industry, while Samsung Electronics used 64 antenna Units Adaptive array transmission technology to solve the problem. The future 5G network transmission rate of up to 10Gbps, which means that mobile phone users in less than a second

Event Causes and analysis This incident is a linkage event, mainly divided into two parts: 1, the Dnspod site's DNS server by more than 10Gbps traffic DDoS attack the suspect because it is the competition between the network game between the business, causing a server operators launched thousands of zombie hosts to Dnspod launched a DDoS flood attack, Causes the DNS server to overload and the line to jam. 2, Storm audio and video of a large number o

heat, power and other problems. HTML5 is also unable to play rtmp directly, so you can see a lot of live streaming on the mobile page, which is pushed by HLS below.Protocol complexity:The RTMP protocol is much more complex than HTTP, resulting in poor performance. Test found that two servers directly connected to the 100GBPS network, HTTP can run to 60Gbps, but rtmp can only run to 10GBPS,CPU occupancy rate rtmp is much higher. Complex proto

motherboard The M.2 interface can support both PCI-E channel and SATA, in which the former is easier to improve speed, theoretical bandwidth 10Gbps, it can be said that it also broke through the SATA interface theory transmission bottleneck. Today's m.2 interface to the PCI-E 3.0 x4 channel, the theoretical bandwidth reached 32Gbps, compared to the previous level of a lot of improvement, which also allows the SSD performance potential increased sign
