“What’s your IPv6 strategy?”

"What's your IPv6 strategy?"

For many in enterprise networking, IPv6 is just a distant memory of a tedious mandatory training a few years back. Weird addresses, over-eager trainer, stories about v6 adoption that never came true. Why then for the last couple of years have I been presenting to Aruba audiences about IPv6 adoption? While many network engineers maybe unaware, IPv6 is very much upon us and numerous times this year I've heard from various sources, 'What's your IPv6 strategy?'

It's alive!

Turning back the clock a few years and IPv6 was for the specialist or for university campuses eager to deploy the latest technology. Live deployments of IPv6 outside of academia were largely unheard of. Then came the ISP deployments across the global, in roughly 2015-2017. Now IPv6 was out in the wild and in our homes. It was this transition of IPv6 from the textbook to the live networks around us that changed the nature of the protocol and breathed life into those 128 bits.
But this was a largely silent change. No big fanfare, hashtags or broadsheet ads. No proliferation of start-ups hunting VC money. No LinkedIn profiles being updated with 'IPv6 thought-leader'. For that reason I feel many network Continue reading

Flow metrics with Prometheus and Grafana

The Grafana dashboard above shows real-time network traffic flow metrics. This article describes how to define and collect flow metrics using the Prometheus time series database and build Grafana dashboards using those metrics.
Prometheus exporter describes an application that runs on the sFlow-RT analytics platform that converts real-time streaming telemetry from industry standard sFlow agents. Host, Docker, Swarm and Kubernetes monitoring describes how to deploy agents on popular container orchestration platforms.

The latest version of the Prometheus exporter application adds flow export.
global:
  scrape_interval:     15s
  evaluation_interval: 15s

rule_files:
  # - "first.rules"
  # - "second.rules"

scrape_configs:

    metrics_path: /prometheus/metrics/ALL/ALL/txt
    static_configs:
      - targets: ['10.0.0.70:8008']

The above prometheus.yml file extends the previous example to add two additional scrape jobs, sflow-rt-src-dst-bps and sflow-rt-countries-bps, that return flow metrics. Defining flows describes the attributes and settings available to build Continue reading

Innovation Exercises to Increase Your Personal Creativity

To advance in most careers these days you need to be creative and able to think outside of the box, but this is easier said than done. As children, we freely use our imagination and our creativity, but as we mature we are often asked to leave our imagination behind in order to perform in the “real world.” So how do you get back that personal creativity as an adult? Here are some innovation exercises that will help you increase your personal creativity.

5 Innovation Exercises to Boost Brain Power and Creativity

Try Looking at Things from a New Perspective

Over time, it becomes ingrained in us to look at things from one given perspective; however, learning to look at things from a different perspective may help us to see things in a different light and spur creativity. For example, if you normally view that tree in your backyard from a distance, why not sit under its branches and look up. Close your eyes, inhale deeply, and touch its leaves and branches, “seeing” it not through your eyes but through your sense of touch or smell. This will help you to see the tree more creatively than by simply Continue reading
