Why Are Dynamic Routing Protocols Used?

Why are dynamic routing protocols used is usually asked by newbies in the networking field, especially after they have heard about routing protocols. Besides that, they often asked this question: What is the difference between static routing and the dynamic routing protocols? And the common answer is that dynamic routing protocols are scalable. In other words, […]

IDG Contributor Network: Cloud provider DigitalOcean heads to the subcontinent

News today from DigitalOcean, the little engine that could of the cloud world. Despite being a relative unknown, at least compared to the big three of Amazon Web Services, Microsoft Azure and Google Cloud Platform, DigitalOcean has managed to grow incredibly fast in its short life.The company, which is headquartered in New York City, has a massive 700,000 customers globally, customers who are attracted to its super-simple offering. DigitalOcean offers the simplest of products, in contrast to the other cloud vendors that give customers a plethora of different options.While that simplicity may be a problem if and when DigitalOcean wants to go up market, for the moment it is scooping up hundreds of thousands of grassroots developers in its main market of the U.S. and Europe.To read this article in full or to leave a comment, please click here

Dell’s private buyout shortchanged shareholders, court rules

Michael Dell and Silver Lake Partners paid about 22 percent too little for Dell when they took the company private in 2013 and will have to pay millions of dollars more to shareholders who opposed the deal, a Delaware court ruled on Tuesday.Though the buyers paid $24.9 billion, or $13.75 per share, the company's actual fair value at the time was $17.62 per share, according to Delaware Vice Chancellor Travis Laster.The decision comes in response to a lawsuit brought by a number of Dell investors who felt shortchanged by the deal. Through what's known as an appraisal suit, they asked the Chancery Court to determine the fair value of their shares at the time.To read this article in full or to leave a comment, please click here

Review: Microsoft masters microservices

Many businesses either have implemented or claim to be implementing microservice architectures, for better or for worse. Microservice architectures give you strong module boundaries, independent deployment and independent scaling of lightweight pieces, isolation of concerns, and the opportunity to use whatever technology is appropriate for each small service. On the other hand, distributed systems inherently have higher latency and more opportunities for failure than monolithic systems, as well as higher operational complexity, so the application has to be “big enough” to justify the overhead of being distributed.To read this article in full or to leave a comment, please click here(Insider Story)

Security concerns rising for Internet of Things devices

The burgeoning market for gadgets that trigger a sprinkler system, help you count the number of times you swing a bat, or dim the lights automatically are rising.That’s a concern for any business due to how these devices are also starting to show up at the corporate office for use in conference rooms, executive suites, and even as a low-cost building security camera system. Experts claim the industry is not doing enough to protect these devices.To read this article in full or to leave a comment, please click here

Father’s Day 2016 gift ideas for the discerning geek techie

Going above and beyond the typical Dad giftI’ve been a father for a decade now, so I’ve become accustomed to getting a lot of Father’s Day gifts from my wife and kids. At first it was the “Draw something cute for Dad” type of gifts, or my wife took over and got me some really cool stuff. With the kids getting older, though, I’m entering the “Typical gifts for Dad” era of my life, where I’ll end up with things like “Hey, Dad, here’s a tie” or “Hey, want this cool coffee mug?” even though I don’t wear ties or drink coffee.To read this article in full or to leave a comment, please click here

Join a Conversation on Network Virtualization with Leading NSX Industry Experts on June 15th

As technology continues to rapidly evolve, network virtualization is now applied to every aspect of the data center. Before you virtualize your network, it’s important to understand what makes sense for your business, and why. To give you the tools for your next step, we’ve gathered top VMware NSX® industry experts for an open panel discussion on the importance of the network in a virtualized world.

Sign up for our NSX panel webcast on 6/15 and discover valuable insight from these industry leaders. No slides, no scripts, just an open conversation.

Moderated by Joshua Soto, VMware Sr. Product Marketing Manager in Networking & Security, our NSX team will start the session with a discussion on network virtualization and how it completes the virtualization infrastructure.

Docker DHCP

Docker controls the IP address assignment for network and endpoint interfaces via libnetwork’s IPAM driver(s). On network creation, you can specify which IPAM driver libnetwork needs to use for the network’s IP address management.

Libnetwork’s default IPAM driver assigns IP addresses based on its own database configuration. For the time being, there is no IPAM driver that would communicate with an external DHCP server, so you need to rely on Docker’s default IPAM driver for container IP address and settings configuration.

The need for external DHCP server support has been identified, however, there is currently no sign that libnetwork developers are working on it. There are community efforts to produce a DHCP IPAM driver, but are currently not production ready.

If you critically rely on your DHCP for IP address management in your production, you can use pipework for the time being.

Alternatively, you can use both DHCP and Docker’s default IPAM on the same Layer 2 segment (a segment that covers both the physical network and the Docker hosted macvlan), with DHCP server providing data for hosts outside Docker host and IPAM providing data for Docker containers. In this case you should split the IP space Continue reading

I try out MSI’s Backpack PC portable VR gaming rig

When the combined armies of Zorg are firing photon weapons at you, 5 kilograms doesn't seem like much. Even the cables and straps that are a necessary part of MSI's Backpack PC fade into the background when you're immersed in a virtual reality game. That's what I discovered when I took MSI's new Backpack PC for a test spin on Wednesday at Computex in Taipei. The device is an entire gaming PC built into a backpack that allows for completely untethered virtual reality gaming. Current VR games run on a computer that sits on a desk or floor and stubbornly won't move as you jump around in a virtual world. It means long cables are needed and that can be a hazard and a hassle.To read this article in full or to leave a comment, please click here

Reserved Internal Address Ranges

The
I’ve added a new question to my own network integration checklist, specifically when integrating chassis-based or integrated solutions:

Does the system use any reserved internal address ranges?


Some chassis-based systems reserve private IP address ranges for inter-card communication. This is a perfectly fine setup as long as you, the network integrator, know what ranges are in use. However, you’ll have a frustrating case of ‘disappearing packets’, if you’re not aware that these ranges are in use. 
I first saw this issue  on an IXIA XM12 chassis a few years back. As I later discovered, each line card received a /24 from an RFC1918 address range. The supervisor used an IP address in each range to communicate with each line card. When I used a conflicting range in my testing the chassis would swallow my packets, and I was left scratching my head until I figured this out.
I thought this was a one-off, but I hit it again recently on an Ericsson Call Control Node. Same problem, but a little easier to detect this time. Nevertheless, I’ve been stung twice now on this issue, so I’ve added to my checklist and brought it to your attention.
If an appliance uses a reserved Continue reading

Report: Comcast and T-Mobile up, AT&T down in latest telecom customer service ratings
