![]() ![]() Laying new high-speed cable is just one improvement. “Those companies are making that fundamental investment to support their businesses,” says Erik Kreifeldt, a submarine-cable expert at telecommunications market-research firm TeleGeography in Washington DC. Microsoft and Facebook are laying another cable across the Atlantic, to start service next year. Google has partnered with 5 Asian telecommunication companies to lay an 11,600-kilometre, US$300-million fibre-optic cable between Oregon, Japan and Taiwan that started service in June. That is why they are spending billions of dollars to clear the traffic jams and rebuild the Internet on the fly-an effort that is widely considered to be as crucial for the digital revolution as the expansion of computer power. Internet companies are painfully aware that today's network is far from ready for the much-promised future of mobile high-definition video, autonomous vehicles, remote surgery, telepresence and interactive 3D virtual-reality gaming. Consumers can already feel those constraints when mobile-phone calls become garbled at busy times, data connections slow to a crawl in crowded convention centres and video streams stall during peak viewing hours. The resulting digital traffic jams threaten to throttle the information-technology revolution. But service levels are much lower on local links, and at the user end it can seem like the electronic equivalent of driving on dirt roads. The copper lines that originally formed the system's core have been replaced by fibre-optic cables carrying trillions of bits per second between massive data centres. But the incident was just one particularly public example of an increasingly urgent problem: with global Internet traffic growing by an estimated 22% per year, the demand for bandwidth is fast outstripping providers' best efforts to supply it.Īlthough huge progress has been made since the 1990s, when early web users had to use dial-up modems and endure 'the world wide wait', the Internet is still a global patchwork built on top of a century-old telephone system. The channel, HBO, apologized and promised to avoid a repeat. Some 15,000 customers were left to rage at blank screens for more than an hour. To change connection parameters, left-click the SetNetworkThrottling method label in the script body and customize connection parameters on the editing pane, located to the left of the script code area.On June 19, several hundred thousand US fans of the television drama Game of Thrones went online to watch an eagerly awaited episode-and triggered a partial failure in the channel's streaming service. If necessary, adjust the Download Speed, Upload Speed, and Latency (round-trip delay in connection).Then select a network speed you want to apply to the script execution. ![]() From the context menu, select Network > Throttling.Right-click the line (step), after which the throttling should be activated.The following network connection options are available in EveryStep Web Recorder: Upon configuring network throttling, you can use a network connection type from presets or set up custom parameters, for example, for Wi-Fi speed emulation. Generally, network conditions are specified by download and upload speeds, as well as round-trip delay (ping latency). Network throttling allows you to slow down or speed up Internet service speed to emulate the experience of real users, so you can see how your web applications will behave in specific network conditions. For example, network connections of the device you use for recording a monitoring script can be faster than the network connection of a real end user. Network connection varies on different devices. When it comes to monitoring your web application performance, it’s necessary to not just emulate user actions, but also network conditions of end-user devices. ![]()
