This network design uses global/regional MPLS backbone as primary WAN connectivity method, with Cisco DMVPN backup. DMVPN spokes should have a regional primary hub with secondary hubs also based on location.

June usually signals two things in my household: the end of the school year, and the beginning of the trips to the multiplex for the latest family-friendly animated movie. This year is no different, and from everything we’ve heard, Disney / Pixar’s latest entrant, Inside Out, is a winner.
While animated and emotion-based avatars are cute and funny, it’s the reverse concept that’s driving a lot of service provider thinking. And that is, thinking from the ‘Outside In’.
What do I mean by this? It all depends on the point of view. For a service provider that’s managing a network, be it global, regional, or metro, there’s a natural tendency to think about starting from the core and extending it out to edge. For this network, it’s important to have a reliable, super fast core – big fast iron that can process packets and bandwidth at really fast rates.
This is certainly important, but in order to differentiate and add value to their customers, service providers are investing more at the edge. They are thinking about how to wrap up and package network functionality, offer these up as monetized services, and distribute these all the way to the customer premises. Continue reading
I’m recently been running down (or is it through) the Linux, systemd, networkd, udevd rabbit hole at full pelt and thought perhaps now was a good time to come up for some air and to share what I’ve learned so far. I could (and have elsewhere) written long essays on why Linux makes an excellent network […]

EOS takes a step closer to SDN by integrating with Nuage and NSX controllers.
The jabber-config.xml file is an essential piece of configuration for the Jabber client. Sure, the client has the ability to operate just fine without this file. Video calling, deskphone control, instant messaging, etc. all work flawlessly. However, if you need to add any additional options, policies, or directory integrations, the jabber-config.xml file becomes necessary. Within the realm of the CCIE Collaboration certification, we are specifically concerned about two different configurations: UDS Directory Integration and SIP URI Dialing.
User Data Service (UDS) simply put, is the name for the End User database within Cisco Unified Communications Manager (CUCM). It contains all relevant information about that user, as would any other directory. UDS, however, is not enabled by default on the Jabber client. In fact, Jabber is geared towards integration with an LDAP source “out of the box”. This means that we must instruct the Jabber client to use UDS if we would like to be able to search the CUCM database to communicate with other users. Since this will have to be done by using the jabber-config.xml file, we must first determine how to create it. Thankfully, the Cisco documentation does not disappoint in this regard. From the Continue reading
This is a liveblog from the day 2 general session at DockerCon 2015. I was running late from some early morning meetings (sorry folks), so I wasn’t able to catch the first part of the general session (about the first 15 minutes or so). Here’s what I was able to capture.
Chris Buckley, Director of DevOps at Business Insider, took the stage to provide an overview of how Business Insider (BI) started using Docker. Buckley provides some “lessons learned”:
This led BI to Fig (now Docker Compose), which led to a decrease in the time it took to get a development environment up and running. With the combination of Vagrant and Docker, BI was able to reduce that to just a couple of hours. When BI revisited production apps, they turned to use Upstart/SysV scripts for containers, but this wasn’t quite the right fit. BI turned back to Puppet, building a parameterized Puppet class to create containers, links, set environment options, and define dependencies on other containers/services starting first.
Before Docker, the workflow was developers to GitHub to Jenkins, which then pushed to Continue reading
A new use case explains how on-premise vCPE virtualizes common network functions to a commercial, off-the-shelf (COTS) platform.
Silver Peak gets into the SD-WAN market with Unity EdgeConnect, a new product that aims to make it easier to provision, manage, and monitor WAN connectivity for remote and branch offices.

Ivan raises good points about SD-WAN and interoperability on his blog today. But I think the benefits of SD-WAN are too good to wait for ten years for standards to catch up. Oh, and its up to you to demand standards from the vendors.

In 2014, Arista was telling me that SDN was "Still Don't kNow" and "Still Does Nothing". In 2015, Arista releases their CloudVision™ SDN controller for cloud networks.
