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

domain.The partitioning process of VLANsSingle Switch PartitioningCan be partitioned directly in the switch configuration.multi-Switch partitioningYou must explicitly set the shared port between the access port and the switch for each VLAN.About the division of VLAN, here is not detailed, can self-Baidu.Low to High speedEthernet based on the transmission media and transmission rate combination classification standards, transmission media are divided into twisted-pair cable, multimode fiber and

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

standards have not been formally introduced, 6 types of system installation specifications and methods are not currently formed, more importantly, 6 or 7 types of systems testing specifications and methods have not yet. Currently commonly used testing equipment is still based on the 100MHZ standard, so even if the user in the project using 6 categories of products, it is not known whether the wiring system used to meet the 6 type of system requirements.

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

Usb-c interface Everyone may not be unfamiliar, Apple recently released a Mac 12 notebook only equipped with a USB-C interface to become the focus of digital enthusiasts, but also to allow more friends to recognize the Usb-c interface. What is the Usb-c interface? What is the difference between it and the USB interface we are familiar with? With a series of questions, this article will be revealed. Figure is the Usb-c interface with Mac 12 　　What interface is USB-C? Usb-c interfac

in the market. To better adapt to IP services, the first Mile Ethernet Federation (EFMA) introduced Epon technology at two-tier Ethernet instead of ATM in early 2001, and the IEEE 802.3ah Working Group standardized it Epon can support a 1.25Gbps symmetric rate and will upgrade to 10Gbps in future. Epon products get a greater degree of commercial, because it combines Ethernet technology and PON technology, thus becoming a very suitable for IP Service

. Instead, iSCSI offers a relatively inexpensive choice for shared storage because the NIC is typically far cheaper than fibre Channel HBAs and converged network adapters. Multipath is difficult to configure before the latest version of Vsphere, but this has been improved. In addition, iSCSI connection speeds are currently limited to 1Gbps and 10Gbps. Finally, the security of iSCSI devices is more complex for administrators because their functionality

and a founding member of Openpowerfoundation, so it is reasonable to use the BlueLink specification. TPU2 Panel Connection The two connectors at the center of the front panel look like QSFP interfaces, with copper twisted-pair, not fiber. This supports two network configurations, 10Gbps Ethernet and 100Gbps Intel OPA connections respectively. Two 100Gbps Opa links can be merged to provide two-way 25gb/s bandwidth, which meets the BlueLink specificati

Beijing's PC users are broadcasting. Unlike 2 or fewer users of video telephony, the user and the user can establish a TCP connection between the transmission of audio and video streams, the stream of traffic in the live business scene must be transmitted through the live transmission network, the user's audio and video traffic first to the most recent push-streaming server, and then through the push-stream server to other users. The maximum number of users a single IDC can support is: min (IDC

determined by the comparator (slicer) to 0 or 1, then the data stream is a filter to predict inter-code interference (ISI), and then subtract the inter-code interference (ISI) from the original input signal, thus to a clean signal. To allow the circuit of the DfE equalizer to operate within the circuit's linear range, the serial signal is first automatically controlled by the VGA to enter the DfE signal amplitude.To understand how the DfE works, first look at the impulse response of a

Sd-wan: Software-defined DCI It teams in large and medium-sized enterprises face at least 3 challenges: one is to improve the quality of the multi-datacenter internetwork to ensure backup disaster or cross-global application performance, and second, to effectively manage highly complex branch deployments, and to migrate the static and private features of traditional WANs into dynamic and public cloud environments.

Every year, graphics companies will launch new products to stimulate consumers to upgrade, this year, Nvidia's GTX 1080 has again won a very high degree of concern. In the media test, this video card is called "The New King", its performance surpasses the same level product twice times, is impressive. In addition, the optimization of virtual reality is also a very desirable part. So, how strong is GTX 1080? Let's get to know each other. 　　1. Faster than expected First, Nvidia GTX 1
