Comparable to optical fiber! Wi-Fi transmission speed up to 100 Gbps What is the maximum transmission rate of current WiFi? Is the 11ac technical standard three-frequency 5300 Mbps? Or 11ad 7 Gbps? Or 11ax's 10 Gbps? The answer is 100 Gbps! Yes, this is comparable to the optical fiber transmission speed. Recently, with the efforts of Japanese researchers, it has

Recently, due to work needs to do a remote disaster recovery transfer tool, weekly from Guangzhou server synchronization 5g size of the database backup files to the Beijing server.The first version of the Transport tool developed very simple, two window services, one responsible for sending, the other responsible for receiving, using the socket to establish a TCP link, on the test server to transfer 10g size files no problem.However, after deployment to the production environment, each

First, the summary1, confirmation and retransmission: the receiver receives the message will confirm that the sender sent a period of time after the transmission did not receive confirmation to retransmit.2. Data check3, data reasonable fragmentation and sequencing:The Udp:ip datagram is larger than 1500 bytes and is larger than the MTU. This time the sender IP layer needs to be fragmented (fragmentation). Divide the datagram into pieces so that each

the most cost-saving solution for data interconnection in IDC roomThe advent of the era of big data, the load of a single computer room more and more, considering the number of servers more and more customers, more and more customers, customer data more and more important,IDC Room in order to adapt to the current network environment and customer needs, have to be in a remote room to backup. To ensure data security at the same time, but also to achieve a catastrophic failure of one of the compute

How TCP protocol guarantees reliable transmissionFirst, the summary1, confirmation and retransmission: the receiver receives the message will confirm that the sender sent a period of time after the transmission did not receive confirmation to retransmit.2. Data check3, data reasonable fragmentation and sequencing:The Udp:ip datagram is larger than 1500 bytes and is larger than the MTU. This time the sender IP layer needs to be fragmented (fragmentatio

In the previous article "exploring the message transmission mode in AJAX (I)", I mainly introduced the transmission modes in the common string Plain-text string and XML format, however, in actual development and application, these two methods can basically meet our needs, but in the case of complex object transmission, it is not ideal to use the two

Windows party with uttorent children's shoes open ipfillter can prevent IPv4 traffic to steal, but also have a lot of routers, NAS, as well as Mac party users, with transmission play Pt. The transmission does not provide the appropriate option settings.Transmission listens and connects tracker with the default 51413 port, and when the data exchange connection with Tracker is also turned on using the HTTP pr

　 simply say wireless router wireless signal effective distance is how much? This is unscientific, not rigorous, because the obstacles to the signal is not considered to block, weaken the situation. According to the test, in general home, wireless router signal can be transmitted to about 20-50 meters of distance, if the wall of the building more, it may signal to reach less than 10 meters away; If the indoor wall construction is less, it is possible to reach a distance of 60-70 meters. What is

Objective Data encryption transmission, we often contact a number of ways one is ciphertext transmission, a clear text transmission ciphertext transmission, that is, the data encryption with the key, using the public key to decrypt the data, the transmission channel can be

Many people may not understand the concept of wireless route transmission. Here we mainly analyze the wireless network transmission principle and its impact on the wireless route performance. From dial-up access to Wired Broadband, from Wired Broadband to wireless networks, the development of the network is changing with each passing day. With the gradual maturity of wireless routing technology, the price o

1. Overview USB2.0 uses the shortening of transmission time series (microframe 125us) and related transmission technologies to increase the overall transmission speed from 12 Mbps to 480 Mbps, increasing the bandwidth by 40 times, it provides conditions for the development of high-bandwidth USB interface products. USB2.0 supports full speed and low speed working
