Join Global Celebrations to Inspire the World
The Internet Society’s story has been 25 years in the making.
The foundation for a global community of people dedicated to bringing the Internet to everyone started in 1992. We have come a long way since then, and today our mission has never been more important or challenging.
This milestone year presents a unique opportunity for us all to reflect on our rich heritage, and to consider how we can impact the Internet for the next 25 years. Our community has a critical role in guiding the decisions that must now be taken for the future Internet in today’s rapidly changing world.
This September, to commemorate the Internet Society’s 25th anniversary, we’d like you to join in a series of global celebrations to inspire the world to take action in shaping tomorrow and in ensuring that the Internet remains a positive force for future generations. We will honor innovators and visionaries who advanced the early Internet at our 2017 Internet Hall of Fame ceremony. We will also recognize 25 under 25 next generation leaders who are using the Internet to make a difference for their communities and beyond.
After 18 months of research, we will launch The 2017 Internet Society Continue reading

What does P router mean in MPLS ?
What does P router mean in MPLS ? It is used in MPLS VPN networks mostly but can be used with any MPLS application, use case. This is very important node in MPLS, and crucial to understand MPLS. MPLS is one of the most commonly used encapsulation mechanism in Service Provider networks […]

Choosing a Cloud Provider: 8 Storage Considerations
Here are some tips for evaluating your cloud storage options.
Route-based IPsec VPN on Linux with strongSwan
A common way to establish an IPsec tunnel on Linux is to use an IKE daemon, like the one from the strongSwan project, with a minimal configuration1:
conn V2-1 left = 2001:db8:1::1 leftsubnet = 2001:db8:a1::/64 right = 2001:db8:2::1 rightsubnet = 2001:db8:a2::/64 authby = psk auto = start
The same configuration can be used on both sides. Each side will figure out if
it is “left” or “right”. The IPsec site-to-site tunnel endpoints are
2001:db8:1::1 and 2001:db8:2::1. The protected subnets are
2001:db8:a1::/64 and 2001:db8:a2::/64. As a result, strongSwan
configures the following policies in the kernel:
$ ip xfrm policy src 2001:db8:a1::/64 dst 2001:db8:a2::/64 dir out priority 399999 ptype main tmpl src 2001:db8:1::1 dst 2001:db8:2::1 proto esp reqid 4 mode tunnel src 2001:db8:a2::/64 dst 2001:db8:a1::/64 dir fwd priority 399999 ptype main tmpl src 2001:db8:2::1 dst 2001:db8:1::1 proto esp reqid 4 mode tunnel src 2001:db8:a2::/64 dst 2001:db8:a1::/64 dir in priority 399999 ptype main tmpl src 2001:db8:2::1 dst 2001:db8:1::1 proto esp reqid 4 mode tunnel […]
This kind of IPsec tunnel is a policy-based VPN: encapsulation and decapsulation are governed by these policies. Each of them contains the following elements:
- a direction (

Open-Source Networking Textbook
A month ago I told you how dr. Olivier Bonaventure starts his networking course with IPv6. But there’s more: the full textbook for the undergraduate course (Computer Networking: Principles, Protocols and Practice) is open-sourced and available (in source form) on GitHub.
You might wonder why I’m so enthusiastic, so let me tell you another story…

Automating network troubleshooting with NetQ + Ansible
Network Automation is so hot right now! Joking aside, DevOps tools like Ansible, Puppet, Chef and Salt as well as proprietary tools like Apstra are becoming all the rage in computer networks everywhere. There are python courses, network automation classes and even automation focused events for the first time in the history of computer networks (or at least it feels like it).
For this blog post I want to focus on automating network troubleshooting, the forgotten stepchild of network automation tasks. I think most automation tools focus on provisioning (or first time configuring) because so many network engineers are new to network automation in general. While I think that is great (and I want to encourage everyone to automate!) I think there is so much more potential for network automation. I am introducing Sean’s third category of automation use-cases — OPS!
I want to combine Cumulus NetQ, a fabric validation system, with Ansible to:
- Figure out IF there is a problem (solved by NetQ)
- Figure out WHAT the problem is (solved by NetQ)
- FIX the problem (solved by Ansible)
- AUTOMATE the above 3 tasks (solved by Ansible)
Because I think looking at terminal windows is super boring (no Continue reading
