Unisys unveils invisibility cloak for network traffic

If you are ultra paranoid, what could be better than hiding your network traffic in such a way that no one could possibly intercept it? This is what Unisys is offering with its new Stealth appliance, which could make man-in-the-middle attacks and keylogger exploits obsolete, or at least more difficult to mount.Stealth has been around since 2005 when it was developed exclusively for the Defense Department. Several years ago Unisys took it to commercial enterprises and has paid for various independent tests to try to compromise the system, all of which have failed.This is because Stealth uses four layers of security: each packet is encrypted with AES256, then split into three separate pieces and dispersed across the network, destined for a particular group of users that have to be running its protocols.To read this article in full or to leave a comment, please click here

Open Networking User Group Conference 2014

Today I’m off to NYC for Open Networking User Group 2014. Tech Field Day was at the last ONUG back in October, 2013 and they were kind enough to invite me out to this one. Here’s a quick intro video of ONUG for those that aren’t aware of it – Tom Hollingsworth interviews ONUG creator Nick Lippis:

We have a good group of vendors lined up for similar round-table discussions. I happen to LOVE this format of conversation, especially with the smart folks we’ve seen from vendors like Nuage and Cumulus. I am really looking forward to sitting down and talking tech.

My original outsider’s perspective was that ONUG in general (not counting nerdy Tech Field Day round table discussions) wasn’t really aimed towards the technical folks, but rather at executives, and at other IT decision makers looking for additional choices in networking infrastructure. While there’s certainly a lot of that, I’d like to call out a few sessions/events that really interest the nerd in me (as if I’m not 100% nerd).

Back in February, I had the pleasure of sitting in Kyle Mestery’s presentation on integration with OpenDaylight and OpenStack at the OpenDaylight Summit:

Source-based routing in IPv4 and IPv6 networks

How does the internet work - We know what is networking

In my current studies I did some work about security inside networking data paths. In my recent work I tried to get some experiments done that needed to use source based routing in order to be completed. Like most of scientific work that tries to get from paper to experiment and then to something useful, it failed […]

The New Cool


I thought it was cool to be an MCSE.

The year was 1999. I didn't have any background in IT. I had just graduated and got my degree in Mechanical Engineering, and was struggling to get a job in that field. That's why I switched to IT, and the first thing I learned (FYI my previous computer skills were Warcraft and Doom) was Windows NT server and workstation. For someone without any IT background, Windows NT looked very interesting at that time! So I thought it was cool to be an MCSE, until I attended a CCNA course.

I thought it was cool to be a Network Engineer.

I felt in love to computer networking since the first day of CCNA training. I loved every moment during the 10-day course and in the last day I passed the CCNA exam. There were not many CCNA around during that time, so the certification landed me my first real job as network engineer early 2000. I thought OSPF was so cool, IGP redistribution was amazing, and BGP policy between different AS was an art. And I thought it was cool to be the guy who managed and monitored the corporate network, received Continue reading

PPPOE Speed Challenge

Original content from Roger's CCIE Blog Tracking the journey towards getting the ultimate Cisco Certification. The Routing & Switching Lab Exam

HTIRW: The Business Side of DNS (1)

So your host queries a DNS server to map the name to a location (an IP address), which sets off a chain of queries across a number of servers throughout the Internet. But who pays for all these servers, and how do they make money? To understand the answer to these questions, we need to […]

CRS/ASR Switching fabrics

At the moment I’m going through whitepapers, Cisco Live 365 presentations and IOS XR fundamentals learning about switching fabrics.

Its a steep learning curve, but in its own way its quite fascinating.

There are a lot of acronyms to be mastered, so later on i will post a list that might serve myself and others when looking at these sort of architectures.
