CCDE Experience – Free Webex Session


The next CCDE practical exam will take place on 20th February 2014 at 275 Pearson Professional Centers (PPC) testing facilities worldwide. I'm planning to conduct free webex session of "CCDE Experience" on next Sunday 9th February at 6 am UTC to explain about CCDE program, how to prepare for it, and tips and tricks based on my personal experience taking the exam several times.

The webex session will be conducted in English. This is my personal initiative to promote CCDE program, with disclaimer: no guarantee you will pass the exam after you follow my suggested study plan. I use public material for the session. And I will use the opportunity to introduce my idea of Project DEW. Anyone can join this webex, you just need to register using the link below. I expect no NDA question during the session.

Review: Cloud Architecture Patterns

Cloud Architecture Patterns Bill Wilder Networks support applications. Okay, that might seem a little obvious, but it needs to be said from time to time. In that vein, I often find it useful to get a better grip on the applications people are putting on networks, and how they expect the network to behave. In […]

Quiz #22 – Policy Based Routing (PBR) Problem or Not ?

Your company has 3 sites, each with a dedicated border router, R1, R2 and R3.
Site-1 (R1) and Site-2 (R2) have their own internet uplinks, but Site-3 (R3) connects to internet via R2. A GRE tunnel is built between R2 and R3 and applied an MTU of 1440, due to some constraints in the transit network between them. You notice that traffic between same pair of devices works for TCP 1001 but fails for TCP 1002. What's wrong ?

FAT or Entropy Label?

In this article we are going to see two features that improve the load-balancing in the MLPS Core. Why? In the networking when dealing with redundancy of links or paths we are facing the polarization issue. This problem happens when one of the link is congested. Let’s take the example of LAGs, if the hashing […]

Restoring Trust in the Internet – Part 1

The Internet has a trust problem. With the recent revelations of government surveillance, traffic interception and modification, compromised products, and suspect algorithms, we have serious problems. Greg and Ethan spoke to this briefly on Show 175 regarding the pwning of several firewall products by the NSA, but the issue goes much further than just compromised […]

Why Python?

It’s been really interesting to see the industry in an all-out zerg rush to adopt Python as a skill-set. What is it about this seemingly arbitrary selection in the vast array of programming languages available out there? What is so special about Python that it comes up in nearly every conversation about SDN? This post has been in drafts for some time, and I was motivated to finish it up by this Packet Pushers episode, where Jeremy Schulman and others discuss Python and its impact to networking.

One leg too few? Architectural Best Practice on SSL VPNs

A couple of times in the past month I’ve been asked where a SSL VPN appliance should be deployed in relation to the firewall. In both cases it was relating to the Juniper Secure Access / MAG platform, but best practice should apply equally to any IPSEC or SSL VPN platform, so I thought it […]

The Secret Sauce for Network Services

Tunneling is the Duct Tape of Networking..It is interesting to realize that a big chunk of network features in Data Center, Service Providers and Enterprises use tunneling in one form or another..It would be fun to imagine a “world” without tunnels! Most known MPLS applications are tunneling techniques, for instance in a VPLS/L3VPN Scenario the […]

Networking Field Day 7 – Here We Go Again!

I’m pleased to be invited back for the 7th installment of Networking Field Day in San Jose, CA from February 19th - 21st. This event is part of a series of independent IT community-powered events that give the vendors an opportunity to talk about the products and ideas they’ve been working on, and receive honest and direct feedback from the delegates. The results of this dynamic vary quite greatly - sometimes a vendor doesn’t quite bring their A-game and we let them know.

A New Year, A New Job and New Challenges

Well by the time I get around to clicking “Publish” on this post it will no longer be a secret, and you don’t know how hard its been for me not to talk about this in overly public forums.

As some of you may have heard, after five months of interviews and immigration paperwork, I have accepted a new role with Juniper Networks as a Sr Data Center* Technical Marketing Engineer. This role will see me move to the San Francisco Bay Area in the next week or so, and be based directly out of the Sunnyvale office for at least the next two years.

The Role

This new role is actually quite exciting to me (and a little bit scary) because it takes all of the knowledge and skills I have gained over the last 15 years as a consultant and then makes use them in a different way. Instead of building solutions to individual customer requirements, I will be working with the Solutions Team to help promote solutions that are universal and can scale with user need. I will be working on creating white papers, design guides and helping position Juniper Data Center their solutions.
