Connecting the Unconnected: The Land of Zero Connect
As we move to a more digitally-connected world, the need for Internet access has never been greater. In many parts of the world, the Internet has firmly established itself as a core part of everyday life – and this holds true for everyone from kids to adults to senior citizens. Yet, there remain communities and places around the world that are still offline. In some instances, these are probably the hardest locations to connect. And there are many reasons for this – geography and terrain could be one reason, commercial viability of service provision is another, as is affordability – the capacity of the community to pay for devices and Internet connectivity.
In 2010, the Internet Society Asia-Pacific Bureau launched the award-winning Wireless for Communities Programme. This was a pioneering effort that placed the local community front and centre, with its catchphrase – “for the community, with the community, by the community”.
The focus of the programme is to provide Internet access and connectivity to underserved and unserved rural areas in a holistic manner that leads to socioeconomic empowerment. A key component involves developing communities’ capacity to build and operate the wireless network, and at the same time, empowering them Continue reading

Episode 28 – For the Love of NAT
When it comes to NAT, network engineers love it, they hate it, or the love to hate it. In this episode, Tom Hollingsworth and Nick Buraglio join us to talk about NAT, why it exists, and its continued role in networking.

Don’t Miss Keith Bogart’s Live Webinar! Deciphering Spanning-Tree Technologies
Tune in Tomorrow, May 31st, at 10 am PDT/ 1 pm EDT for a FREE live webinar with expert instructor Keith Bogart (CCIE #4923).
About This Webinar:
Understanding the logic of 802.1d and how it builds a loop-free “tree” is critical to passing any Cisco certification exam. Presented by INE instructor Keith Bogart (CCIE #4923), this session will take you through that logic so that, given any bridged/switched layer-2 network, you can predict what tree will be formed. Ask questions live with an experienced industry expert!
Business-Driven Network Transformation
Understand business requirements before jumping into a network design in order to ensure they're aligned, networking expert says.
Typical EVPN BGP Routing Designs
As discussed in a previous blog post, IETF designed EVPN to be next-generation BGP-based VPN technology providing scalable layer-2 and layer-3 VPN functionality. EVPN was initially designed to be used with MPLS data plane and was later extended to use numerous data plane encapsulations, VXLAN being the most common one.
Design Requirements
Like any other BGP-based solution, EVPN uses BGP to transport endpoint reachability information (customer MAC and IP addresses and prefixes, flooding trees, and multi-attached segments), and relies on an underlying routing protocol to provide BGP next-hop reachability information.

Towards a design philosophy for interoperable blockchain systems Hardjono et al., arXiv 2018
Once upon a time there were networks and inter-networking, which let carefully managed groups of computers talk to each other. Then with a capital “I” came the Internet, with design principles that ultimately enabled devices all over the world to interoperate. Like many other people, I have often thought about the parallels between networks and blockchains, between the Internet, and something we might call ‘the Blockchain’ (capital ‘B’). In today’s paper choice, Hardjono et al. explore this relationship, seeing what we can learn from the design principles of the Internet, and what it might take to create an interoperable blockchain infrastructure. Some of these lessons are embodied in the MIT Tradecoin project.
We argue that if blockchain technology seeks to be a fundamental component of the future global distributed network of commerce and value, then its architecture must also satisfy the same fundamental goals of the Internet architecture.
The design philosophy of the Internet
This section of the paper is a précis of ‘The design philosophy of the DARPA Internet protocols’ from SIGCOMM 1988. The top three fundamental goals for the Internet as conceived Continue reading

Windows Updates and Ansible
Welcome to the fourth installment of our Windows-centric Getting Started Series!
One of the duties of most IT departments is keeping systems up to date. In this post we’re taking a quick look at using Ansible to manage updates on your Windows nodes. Starting with a small example of six Windows machines, we’ll show an example of a play against those hosts. We’ll share the full example at the end.
Updates, Updates, Updates...
Managing Windows updates is something that can be understood and customized quickly with Ansible. Below is a small-scale example of running updates on hosts with some flexibility in what gets updated in the process. The example here is assuming a domain exists and the hosts are being passed domain credentials. If you’re looking to test this example, be sure to read Bianca’s earlier Getting Started post on connecting to a Windows host.
Because this example is running against exclusively Windows machines, the information needed to connect can be included in the inventory file:
[all:vars]
ansible_connection: winrm
ansible_user: administrator
ansible_password: This-Should-Be-a-Password!
For Example
The example hosts include three groups of servers, two in each group. There are terminal servers, application servers, and directory servers. For the purposes of Continue reading
