I was really excited when Juniper announced Junos Fusion. I hoped for QFabric Done Right, but after watching the NFD10 video describing the architecture, I was disappointed: they reinvented Fabric Extenders.
The blog post was slightly updated on November 14th 2015 based on feedback received from Juniper engineers.

At first, I wasn't sure how well the remote lifestyle would suit me, but after a short time I settled into a very comfortable routine. And to my surprise, I discovered that I was much more productive working from the serenity of my home office than I ever was in a cubicle. I'd like to share my observations with the hope of convincing others to try ditching the office as well.
This is the most obvious benefit to working remote. No more sitting in rush hour traffic twice a day. Even if you take public transit and are able to play on your laptop for most of the trip, commuting is a major time sink. Most people will instantly gain back at least an hour of time by foregoing the daily drive to and from the office. What could you do with an extra hour each day?
And beyond time, there are ample corollary benefits. You (or your company) are no longer paying for as much fuel or fare. You're greatly reducing your risk of being injured Continue reading

Nuage unifies virtualized network services on CenturyLink's Programmable Services Backbone.
While I was at Kubecon this past week, one of the presenters showed off a handy CLI tool for working with JSON. It’s called jq, and in this post I’m going to show you a few ways to use jq. For the source of JSON output, I’ll use the OpenStack APIs.
If you’re not familiar with JSON, I suggest having a look at this non-programmer’s introduction to JSON. Also, refer to this article on using cURL to interact with a RESTful API for a bit more background on some of the commands I’m going to use in this post.
Let’s start by getting an authorization token for OpenStack, using the following curl command:
curl -d '{"auth":{"passwordCredentials":
{"username": "admin","password": "secret"},
"tenantName": "customer-A"}}'
-H "Content-Type: application/json"
http://192.168.100.100:5000/v2.0/tokens
This will return a pretty fair amount of JSON in the response, and it presents the first opportunity to use jq. Let’s say you only wanted the authorization token, and not all the other output. Simply add the following jq command to the end of your curl request:
curl -d '{"auth":{"passwordCredentials":
{"username": "admin","password": "secret"},
"tenantName": "customer-A"}}'
-H "Content-Type: application/json"
http://192.168.100.100:5000/v2.0/tokens |

- There are many hub sites.
- Spokes will be network-near exactly one hub site.
- Latency between hub sites is high.
- Bandwidth between hub sites is low.
- Spoke routers don't know where they are in the network.
- Spoke routers must connect only to the nearest hub.
