From the Desk of Jarrod Mills :: Updated R&S Material is on the Way!
Over the next few months, several enhancements and upgrades to the CCIE Routing and Switch product line will be rolled out. I am currently doing a thorough review of the Volume 1 Workbook to ensure that every topic within the Version 5 Blueprint is thoroughly tested and validated. Shortly thereafter, I will be editing and compiling the complete Volume 2 Mock Lab workbook with 5 full 8-hour labs. These labs will fully prepare students for success on the rigorous Cisco CCIE lab exam.
After listening to the feedback of current and prospective students, I realized that the Troubleshooting and Diagnostic Sections were a stumbling block for many and that these sections were under-represented in the current training program. As a result, new Troubleshooting and Diagnostic workbooks are currently under development with a target completion date within the next 2 months. The Troubleshooting workbook will contain 50 tickets that are similar in difficulty to the tickets the student will experience in the Cisco lab exam. Similarly, the Diagnostic workbook will also contain 50 issues and be designed to allow students to hone their skills, and become confident in their ability to identify and choose the correct solution(s) in this section of Continue reading
Networking Field Day at Cumulus Networks – Recap
Networking Field Day is not your typical event; it is an interactive forum where vendors present to selected networking industry experts.
Feb 11, 2015 was our first Networking Field Day at Cumulus Networks and as many have commented, it was “very informational” and an “excellent” presentation. So, for those of you that could not make it, here is the recap with the recordings.
Being an atypical event, #NFD9 had to start off differently with…. a grandiose entrance from the delegates in a limo and some first-class espressos powered by the Cumulus Networks team before getting off to an exciting 2hours forum.
Cumulus Networks Overview
Kicking off the session was JR Rivers (@JRCumulus), Co-founder and CEO of Cumulus Networks for a straight conversation and great anecdotes on Cumulus Networks and what makes Cumulus Linux different. “Cumulus Linux is fundamentally & unashamedly Linux!” What sets Cumulus Networks apart from others? The responsibility to take patches upstream, the real partnerships, being an enabler rather than a gatekeeper.
Data Center Architectures
What architectures are best suited for today’s date center network? And how does Cumulus Networks make it easier to build networks? Dinesh Dutt (@ddcumulus), Chief Continue reading
Let’s Meet at Interop Las Vegas 2015
I will be at Interop Las Vegas this year from Tuesday, April 28 through Thursday, April 30. If you are a vendor who would like to brief me, someone who would like to explore consulting opportunities, or if you just want a word, let's connect. I'd be happy to swing by your booth, meet for coffee, or simply hang out.The Buzz About NetBeez
One of the great benefits of attending Tech Field Day events is the opportunity to learn about new startups that I might otherwise not have heard about. And one of the great things about startups is their ability to apply a fresh set of eyes to long-standing problems without being bogged down by existing products or past decisions.
The problem I’m thinking of in this case is monitoring the network right out to the user edge in a cost-effective manner. Network performance monitoring platforms tend to be network-centric, looking at port statistics and reachability from the monitoring platform to the access switch. Application performance monitoring tools often monitor from a single, central point of the network either generating transactions or trying to intercept user transactions and interpolate performance characteristics while deriving performance stats. Each of these solutions can have a place, but neither one really gives you a view from the ground. Existing options to get a user-like view that really comes from the edges of your network (where the users are, after all) are very limited. Enter NetBeez, with a very simple premise: Monitor from the edge. Every edge. Wired edges. Wireless edges. From the user’s perspective. And use a central, or cloud-based, dashboard Continue reading
Peering with Route Servers
Original content from Roger's CCIE Blog Tracking the journey towards getting the ultimate Cisco Certification. The Routing & Switching Lab Exam
As your network grows bigger and your internet traffic grows, it starts to make sense to peer directly with other networks rather than simply pay an ISP to deliver all that traffic. Peering is one of the areas in life where the Pareto principle, also known as the 80-20 rule applies: 20% of your potential... [Read More]

SEGMENT ROUTING
Segment routing is a source routing mechanism which provides Traffic Engineering , Fast Reroute, MPLS VPNs without LDP or RSVP-TE. Very simple but powerful solution,when you read the post you will ask more information, because it solves the complex problems with some extensions to existing protocols. MPLS provides BGP free core, VPN services (Layer2 and… Read More »

IoT: Don’t fret about the world of tomorrow
IoT: Don't fret about the world of tomorrow
by Brian Boyko, Contributor - February 17, 2015
The Internet of Things is a big deal. But – as CIMI Corp. President Tom Nolle wrote in a recent blog post titled “My Thermostat Doesn’t Want to Talk to You” – it is probably not going to be a big deal for network management.
We’ve heard all sorts of applications of smart technology, such as refrigerators that know when you’re running low on milk and can send a text to your smartphone when you’re in the vicinity of a supermarket; thermostats that know when you’re working late at the office so you don’t have to have the heat turned on exactly at 6pm, etc. Early adopters already have all these things. But other than the basic Internet connectivity needed to send these little pieces of data back and forth, network management – as an industry and as a profession – is probably going to be almost unaffected by it.
Think about it. For many purposes, the Internet of Things provides the most value coordinating between different items in your home.
In our “world’s fair house-of-the-future,” much of Continue reading
5 keys to successful SIP implementation
This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.
Voice over IP uses the session initiation protocol (SIP) to convert phone conversations to data and send it through a public or private IP network instead of using telephone lines or fixed bandwidth T1 and T3 options. This can be a brilliant way to cut costs, gain flexibility and more efficiently use existing resources, but consider these issues to ensure successful implementation:
* Native SIP. Ask your carrier if their network was designed to deliver SIP end-to-end and the size of their local telephone number footprint. SIP is an open standard protocol used to enable VoIP. Make sure your carrier isn’t patching together multiple networks, which may or may not use SIP and could cause quality degradation and make troubleshooting issues more difficult.
