Connection technology In Network

• ↞←Many technologies are available for wide area network links. Examples include circuit switched telephone lines, radio wave transmission, and optic fiber. New developments in technologies have successively increased transmission rates. In ca. 1960, a 110 bit/s (bits per second) line was normal on the edge
  
  of the WAN, while core links of 56 kbit/s to 64 kbit/s were considered fast. As of 2014, households are connected to the Internet with Dial-Up, ADSL, Cable, Wimax, 4G or fiber The speeds that people can currently use range from 28.8 Kilobits per second through a 28K modem over a telephone connection to speeds as high as 100 Gigabits per second over an Ethernet 100GBaseY connection.

• AT&T plans to start conducting trials in the year 2017 for businesses to use 400 Gigabit Ethernet.^[4] Researchers Robert Maher, Alex Alvarado, Domaniç Lavery & Polina Bayvel of University College London were able to increase networking speeds to 1.125 Terabits per second.^[5] Christos Santis, graduate student Scott Steger, Amnon Yariv, Martin and Eileen Summerfield developed a new laser that quadruples transfer speeds over fiber optic cabling.^[6] If you multiply 1.125 times 4 on your calculator (the amount of terabits per second achieved by
  
  University College of London researchers times the laser technology that quadruples transfer speeds over fiber optics developed by Caltech researchers) you get 4.5, and that means that with the two technologies combined that currently exist we could have 4.5 Terabit per second internet speeds available to the public sometime in the near future.

Understanding Speed Test Results In Network

To check the connection speed of a computer network requiresspeed test and interpreting the results. A speed test measures the performance of a network during a

running some kind of   
(usually short) period of time. The tests normally send and receive data over the network and calculate performance according to (a) the amount of data transferred and (b) how much time was required.
The most common measurement for network speed is data rate, counted as the number of computer bits that travel over the connection in one second. Modern computer networks support data rates of thousands, millions, or billions of bits per second. Speed tests also often include a separate measurement for network delay, sometimes called ping time.

What's considered "good" or "good enough" network speed depends on how the network is being used. For example, playing online computer games requires the network to support relatively low ping times and the data rate is often a secondary concern. Watching high-definition video, on the other hand, requires support for high data rates and network delays are less of an issue

Vertiv To Reach Additional Edge/Internet of Things Applications with Features of Latest Serial Console Appliance

Columbus, Ohio [May 08, 2017] – Vertiv, formerly Emerson Network Power, today announced a new compact serial console that will extend their portfolio of Internet of Things (IoT) enabled devices, offering a solution for remote monitoring, out-of-band management and IoT connectivity for market segments beyond the traditional data center. The new Avocent® ACS800 serial console leverages the technology platform of the Avocent ACS8000 serial console launched in the Fall of 2016, but brings a compact form factor and a cost-efficient connectivity feature set that makes the new design accessible to users who have previously been constrained by limited space or budget. The Avocent ACS800 serial console will have select product availability in June and global availability in Q3 of this year.

This additional product platform demonstrates a continuing push by Vertiv to modernize the role that serial consoles can serve within networks. While maintaining high availability and providing remote management of IT equipment remain cornerstone features of the new Avocent ACS800 serial console, the compact form factor and low-cost pricing position, coupled with new target connectivity features, make this solution a good fit for Edge and IoT focused market segments, including users with multiple remote locations, such as education, financial and retail.

“Vertiv is investing in the development of IT management products that focus on the needs of Edge customers by creating an ecosystem of connectivity. Our broad portfolio for diverse segments is unique in the market,” said Jay Wirts, vice president and general manager of IT management products for Vertiv. “Our new Avocent ACS800 ties seamlessly into rack power distribution and uninterruptible power supply systems,  as well as providing the ability to connect remote Edge sites with environmental monitoring sensors, USB devices and even other building systems like automated transfer switches and HVAC control systems. The key to harnessing these features is to package them in a way that meets the size and budgetary constraints of the customer.”

The Avocent ACS800 models have two, four, or eight serial ports - with multi-protocol serial support including RS232, RS485 and RS422 - four USB ports, an environmental sensor port and a digital output port. Networking connectivity is available through dual Gigabit Ethernet ports, an optional internal analog modem, as well as through an optional external 4G/LTE cellular router available directly from Vertiv and supported through a strategic partnership with Cradlepoint. Mounting of the Avocent ACS800 can be either desktop based, or with one of three available mounting kits: 1U rack mount, wall mount or DIN-rail mounted.

Vertiv made today’s announcement at Dell EMC World in Las Vegas, Nevada.  For more information on the Avocent ACS800 or the expanding portfolio of serial console applications
