Show 224 – HTTP2. Its The Biggest (Network) Thing Happening on the Internet Today – Repost

And the default to encryption means that transparent caches, proxies, IDS/IPS and other network security systems will be seriously impacted.

IP FRR and Micro-loops Part 2
This is a continuation from Part 1 Remote LFA At this point we already know that simple LFA doesn’t always provide full coverage and its very topology dependent. Reason is simple i.e.in many cases backup next hop best path goes through the router calculating the backup next hop. This problem can be solved if we […]

NAT, Security, and Repeating Myself
In a former post I pointed out that we need to think of obscurity as a tool in network security — that we shouldn’t try to apply rules that are perfectly logical in terms of algorithms to networks as a system. While I’m not normally one to repeat myself, this topic needs a little more […]

HTIRW: The IETF Draft Process
In our deeper investigations of the IETF as a “sample standards body” in this (apparently forever running) series on how the Internet really works, let’s take a look at the IETF standards process.

Show 223 – Viptela and the Software Defined WAN
As the industry adoption of SDN gains rapid traction, the Wide Area Network is emerging as the leading use-case (read 2015 is all about SD-WAN).

Use Rate-Limiting to Alleviate Link Saturation
At some point in time you may come across a scenario in which you notice a WAN link at a branch site is being saturated. You then have to weigh your options to mitigate the saturation because it can cause intermittent network outages and other issues. In this scenario we will use rate-limiting on the […]

MPLS TE Design -Part 2
This is a continuation from Part 1 Case for LDPoRSVP As we mentioned at the very beginning that ACME provides L3VPN and L2VPN services, which requires end to end LSP between the PEs. But due to scaling reasons, ACME decided not to extend RSVP to the edge routers. This creates a problem as there is […]

Confessions of technical interviewer
A technical interviewer, or technically an interviewer. I was interviewed quite a few times since I set of to join the networking crowd, 12 years ago. I also had opportunity to sit on the opposite side, and interviewed people on multiple occasions. Some of my fondest memories of working for my current employer are connected […]
