It is often said that there are only problems in the design of IP Routing protocols. Propagation – how routes are notified to all elements on the network. Expiration – how to detect and notify that routes are no longer valid. But most people quickly realise that silent third problem – recursion. […]

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:
Aside from a few Continue reading
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 […]

I have been trying to configure things faster and faster as a bit of personal challenge to myself recently. It is only when the clock is on you that you start to panic. So I have a little challenge. Configure PPPOE between two routers in under 60 seconds. This is the topology This is the […]

Original post PPPOE Speed Challenge
After I get an interesting if it is not weird question about switch selection from someone couple days ago I decided to share my ideas about this specific and actually important topic. Question was exactly like this; ‘ Which one I should buy 24 port or 48 port switch ‘. What would you give […]

I’ve spent a lot of time researching the hardware and technology that goes inside switches and routers. In part this is because I’m in the early stages of a book on White Box Networking where I needed to be able to put together information about the technology but really because software can only deliver what […]

This is Part 2 in a special series looking at the silicon and hardware inside your network device. Although software will be at heart of network innovation, it will still run on hardware and it’s time to expose the internals of our network hardware and understand the hardware architecture inside a typical device. Many people […]

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 […]
Wireshark 802.11 frame type and subtype display filters to quickly sort packet captures.
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.
