Microsoft touts the Edge browser’s battery-friendly traits

Microsoft already has laid claim to its Edge browser being the most battery-efficient Web browser available on Windows 10, and now with the Creators Update, Microsoft touts even further gains in energy efficiency.According to Microsoft’s own tests, Microsoft Edge on Windows 10 Creators Update uses up to 31 percent less power than Google Chrome, and up to 44 percent less than Mozilla Firefox. Before you dismiss it as rather convenient that they did their own tests, they did make the methodology available and provided open-source testing tools for download, so you can run the tests yourself. To read this article in full or to leave a comment, please click here

Optimal Route Reflection


There are—in theory—three ways BGP can be deployed within a single AS. You can deploy a full mesh of iBGP peers; this might be practical for a small’ish deployment (say less than 10), but it quickly becomes a management problem in larger, or constantly changing, deployments. You can deploy multiple BGP confederations; creating internal autonomous systems that are invisible to the world because the internal AS numbers are stripped at the real eBGP edge.

The third solution is (probably) the only solution anyone reading this has deployed in a production network: route reflectors. A quick review might be useful to set the stage.

In this diagram, B and E are connected to eBGP peers, each of which is advertising a different destination; F is advertising the 100::64 prefix, and G is advertising the 101::/64 prefix. Assume A is the route reflector, and B,C, D, and E are route reflector clients. What happens when F advertises 100::/64 to B?

  • B receives the route and advertises it through iBGP to A
  • A adds its router ID to the cluster list, and reflect the route to C, D, and E
  • E receives this route and advertises it through its eBGP session towards G

Worth Reading: PDoS attacks

Imagine a fast moving bot attack designed to render the victim’s hardware from functioning. Called Permanent Denial of Service attacks (PDoS attacks), this form of cyber-attack is becoming increasingly popular in 2017 as more incidents involving this hardware-damaging assault occur. Also known loosely as “phlashing” in some circles, PDoS is an attack that damages a system so badly that it requires replacement or reinstallation of hardware. By exploiting security flaws or misconfigurations, this type of cyber attack can destroy the firmware and/or basic functions of system. It is a contrast to its well-known cousin, DDoS attacks, which overloads systems with requests meant to saturate resources through unintended usage. —radware

IDG Contributor Network: Infrared much better than Wi-Fi

A few special “light antennas” dotted around a room would provide significantly more bandwidth for internet-connected devices than traditional Wi-Fi, says a Dutch scientist. Wi-Fi’s days could be numbered if the technology works as suggested.+ Also on Network World: IoT device sales set to surge in next decade + With this new Wi-Fi replacement system that’s been proposed, benign, infrared rays of light emitted from ceiling-mounted transmitters would beam bandwidth-intensive streams of data at smartphones and laptops within the room. And each ray of light could provide 40 gigabits per second, says Joanne Oh, a Ph.D. researcher at Eindhoven University of Technology (TU/e) in a news article on the university’s website.To read this article in full or to leave a comment, please click here
