Antenna installation guidelines - Free book and presentation

Image
We decided to make available existing antenna installation manuals which are somewhat out of date but still relevant. We are happy that anyone use it freely as long as they acknowledge the source as Poynting Antennas and if they make it available electronically provide a link to the original. Users may also edit, improve and add to these provided we are informed and allowed to publish it and use it ("joint copyright").

Multapplied videos - SDWAN ease of use

Image
Video #1 explains how we gather link information about a link's latency and throughput limits before it becomes part of a bond.
In this video we show how easy it is in our system to activate a bond. We take our three network access links and aggregate them using our Bonded Internet user interface. We then perform a speed test to show you how all three links come together as one.
In this video we demonstrate our same-IP failover technology. We begin a large file transfer over the bonded connection and remove the cable connection, simulating a network failure. The file continues to transfer without interruption.
In this video we turn on our powerful compression/acceleration engine to show you how much increased performance we can get out of our bond.
In this video we show how our system is able to adjust itself to avoid poor bandwidth regions of a given connection. We use Quality of Service to virtually eliminate the effects of jitter and latency on the transmission of vo…

FW1 – 4 Port Intel® J1900

Image
The Vault is a small form factor PC built for use as a firewall / router.  The FW1 is based on a 4 network port design that leverages a low power (10Watts at idle CPU, 15Watts under moderate load), but versatile Intel Celeron J1900 CPU.  The Vault uses standard Intel components (including Intel network ports) which results in compatibility with a variety of operating systems, including a number of open source firewall projects.  The Vault is fanless so it has no moving parts, which results in an incredibly durable platform that can be used in less than ideal environments.  Its all aluminum enclosure (no plastic here) is a giant heat sink, keeping the CPU cool.  The enclosure also comes with pre-drilled holes for an available wireless kit (available here).  The FW1 can accommodate up to 8GB of DDR3L RAM and any available size mSATA storage drive.  For more information on tested OS compatibility with the Vault, please see this link.

The causation over the Azure data centre outage leaves more questions than answers

Image
The September 2018 Azure data centre outage leaves more questions than answers. Microsoft generically sums it up as a cooling issue triggered by lightning storms. In this neck of the savannah we have lightning storms that are the trademark signature weather of the Highveld. We live at an elevation of 1.5 km. My house is the highest one in our burrow and the advertising sign on William Nicol Drive about 200m from my house is regularly klapped by lightning. We are basically immune to the earth shattering sound of thunder and lightning.

SevOne SD-WAN Monitoring Tool Adds Support for Versa Networks

Image
SevOne added support for Versa Networks’ SD-WAN on its SD-WAN monitoring tool. The monitoring tool already supports both VMware’s NSX SD-WAN by VeloCloud platform and Cisco’s SD-WAN service based on Viptela technology.  While SevOne can make its SD-WAN monitoring service work for any SD-WAN vendor, the partnerships with Versa, Cisco, and VMware are out-of-box offerings. SevOne’s monitoring service is built into the each of the vendor’s SD-WAN product fabric to offer network services over the multi-tenant SD-WANs.

Clean up your network with LucidView’s MikroTik Enforcer Portal

Filtering online content on a large network is a difficult task, especially for networks within major companies or those managed by ISPs, Managed Service Providers (MSPs), and Value Add Resellers (VARs).  Whether you are attempting to prevent access to inappropriate content within a corporate environment or block access to illegal content on your network, content filtering can be difficult.

Two Beer Networking - SDWAN Kills Carriers

Image
I think that SD-WAN could totally change the carrier market, in a destructive way, that is good for customers.
MPLS revenue for Private WAN is already declining SD-WAN disrupts the router vendors who have cosy arrangements with carriers (their best customers) by producing devices that don't damage carriers revenue. Is that why startups developed SD-WAN and not Cisco or Juniper ? Multi-carrier networks create arbitrage opportunities that reduce cost of bandwidth by more than 50%. Now that is a "disruptive" technology! Why are we stuck with dumb routers on dumb bandwidth paying dumb prices ? Carriers are hopeless at customer service. Do you really believe that they could manage your firewalls, proxies, QOS etc ? Pfffftttt. Thats why I think carrier NFV is dumb. Customers hate carriers. It could be time for customers to get even.  You can find more like this at Packet Pushers website : http://packetpushers.net We are well know for your podcasts & newsletters…

White Paper Key Requirements for SDWAN

Image
Digital transformation is happening now, and fast. It includes cloud, services, mobile. It’s hybrid, it’s the Internet, it’s the user. Most importantly, it’s the seamless orchestration of all these things together.  True digital transformation is the ability to orchestrate apps, networks, and devices to provide seamless access to digital services for end users.

5 infographics on the potential of the Internet of Things

Image
Despite its rising importance in the tech market, the full potential of the Internet of Things has yet to be unleashed. In the next few years, we will see an explosion of IoT products and applications, not only for the retail market but also in the manufacturing, health, transport and security sectors.  
Here are five infographics that give us a preview of what the burgeoning IoT market has in store for companies and their customers.

The Hierarchy of IoT “Thing” Needs

Image
To define an IoT “Thing,” I’m going to employ Maslow’s hierarchy of needs — that well-known human psychology paradigm typically displayed in the shape of a pyramid, with the most fundamental human needs (physiological needs like air, food and water) at the bottom and rising to the most esoteric needs (self-actualization or expression of full potential) at the apex.  I’ve sketched out a derivative needs pyramid for IoT “Things,” charting their ascent to Thing-actualization.

MPLS explained

Image
The thing about MPLS is that it’s a technique, not a service — so it can deliver anything from IP VPNs to metro Ethernet. It's expensive, so with the advent of SD-WAN enterprises are trying to figure how to optimize its use vs. less expensive connections like the internet.

Network Troubleshooting Guidelines

Image
It all started with an interesting weird MLAG bugs discussion during our last Building Next-Generation Data Center online course. The discussion almost devolved into “when in doubt reload” yammering when Mark Horsfield stepped in saying “while that may be true, make sure to check and collect these things before reloading”.  I loved what he wrote so much that I asked him to turn it into a blog post… and he made it even better by expanding it into generic network troubleshooting guidelines. Enjoy! This is a guest blog post by Mark Horsfield, CCIE#52702, Technical Support Engineer at Cumulus Networks.

Three Blind Phreaks

Image
Inside the chintz-filled living room of the Badir family's neat and modest home, a feast of freshly roasted chicken, saffron rice, and seasoned vegetable stew perfumes the air. Friends and relatives pour through the front door to congratulate 27-year-old Munther "Ramy" Badir. He's just been released from prison after serving 47 months for computer-related crimes. Outside, Islamic prayers resonate from speakers on a truck moving slowly down the dusty streets of Kafr Kassem. Everyone in this Israeli village - populated mostly by Arabs - appears ecstatic to have Ramy back.
