6 must-read internet standards | Reading the source is an important part of open source software. But “read the source” doesn’t apply only to code. Understanding the standards the code implements can be just as important. “Requests for Comments” (RFCs) published by the Internet Engineering Task Force (IETF) are important for Internet technologies. This article collected a few RFCs

The merger of networking, storage, RAM, and cache | EDN–storage–RAM–and-cache Since the dawn of civilization, the computing bottleneck has been the tawdry I/O relationship between disk drives and RAM (random access memory). The emergence of SSDs (solid state drives) loosened but didn’t alter this I/O bottleneck. With fast networks computers can move data onto their disks from remote systems as fast as they can

WPA3 promises more secure WiFi networking

In January, at CES 2018, Wi-Fi Alliance announced that the WPA2 encryption used to protect Wi-Fi (WI-FI) since 2004 will get a new, more secure WPA3. Now standardization is complete and new devices that support wpa3 technology can be certified. The new protocol provides a number of additional protections for Wi-Fi enabled devices. WPA3 networks

Remote Powering over communications cabling (part 3)

Remote feeding is a technology which enables operators to power several remote sites from a central location.  Remote powering implies that the power equipment is not local but some distance away. Remote means that the powering and powered equipment are in separate buildings or at different external locations inside same building.It can be used as

PoE powered device PSU

With PoE (Power over Ethernet) technology, an Ethernet cable can carry power in addition to data. PoE can supply operating voltage to PoE compatible networked devices, such as a WLAN base station, an IP camera, a VOIP phone or IoT device. The original IEEE 802.3af-2003 PoE standard provides up to 15.4 W of DC power
