Enabling the Next Generation of Community Network Builders: A Report on CNXAPAC 2018 and CN Champs

In October 2018, together with our partner Digital Empowerment Foundation (DEF), we organized the 2nd edition of CNXAPAC (Community Network eXchange Asia-Pacific) with a focus on how two sets of community operators – community radio network operators and community (Internet) network operators – could explore synergies in the work they do.

The event was kindly hosted by UNESCO at their Delhi office, and brought together over 50 participants from around the world to exchange knowledge and best practices, and see how the Internet can improve the lives of underserved and unserved communities.

In many parts of the world, community radio stations play an important role in providing information to the public – particularly in rural communities. The community radio community have expertise in setting up radio communications, as well as creating content relevant to their local communities. This presents a wonderful opportunity for this community to add Internet services to their repertoire, and 12 community radio operators from around India were brought to CNXAPAC to learn about Internet community networks, and how these could be deployed in their local communities.

The Internet Society Asia-Pacific Bureau has been working on community networks since 2010 as part of its Wireless for Continue reading

Don’t Sugarcoat the Challenges You Have

Last year I got into somewhat-heated discussion with a few engineers who followed the advice to run IBGP EVPN address family on top of an EBGP underlay.

My main argument was simple: this is not how BGP was designed and how it’s commonly used, and twisting it this way requires schizophrenic BGP routing process which introduces unnecessary complexity (even though it looks simple in Junos configuration) and might confuse people who have to run the network after the brilliant designer is gone.

Intel’s Agilex FPGA family targets data-intensive workloads

After teasing out details about the technology for a year and half under the code name Falcon Mesa, Intel has unveiled the Agilex family of FPGAs, aimed at data-center and network applications that are processing increasing amounts of data for AI, financial, database and IoT workloads.The Agilex family, expected to start appearing in devices in the third quarter, is part of a new wave of more easily programmable FPGAs that is beginning to take an increasingly central place in computing as data centers are called on to handle an explosion of data. Learn about edge networking How edge networking and IoT will reshape data centers Edge computing best practices How edge computing can help secure the IoT FPGAs, or field programmable gate arrays, are built around around a matrix of configurable logic blocks (CLBs) linked via programmable interconnects that can be programmed after manufacturing – and even reprogrammed after being deployed in devices – to run algorithms written for specific workloads. They can thus be more efficient on a performance-per-watt basis than general-purpose CPUs, even while driving higher performance.  To read this article in full, please click here

BrandPost: 3 Essentials for Achieving Resiliency at the Edge

“The IT industry has done a good job of making robust data centers that are highly manageable, highly secure, with redundant systems,” says Kevin Brown, SVP Innovation and CTO for Schneider Electric’s Secure Power Division. However, he continues, companies then connect these data centers to messy edge closets and server rooms, which over time have become “micro mission-critical data centers” in their own right — making system availability vital. If not designed and managed correctly, the situation can be disastrous if users cannot connect to business-critical applications.  To read this article in full, please click here

CCAOI-ISOC Delhi Webinar on the Draft National e-Commerce Policy

The Indian government’s Department for Promotion of Industry and Internal Trade has released a draft of the National e-Commerce Policy for public comments by 29 March 2019. The CCAOI, with support from the Internet Society India Delhi Chapter, organized a webinar to discuss the draft policy on 18 March. The objective of the discussion was to inform various stakeholders of the provisions of the draft policy and highlight issues of concern. Watch the recording here.

The session was moderated by Subhashish Panigrahi and myself. It was attended by over 45 participants from different stakeholder communities across the country. The speakers that participated in the session were Devika Aggarwal from NASSCOM, Ankit Anand from Reliance Jio, Nikhil Pahwa from MediaNama, Parminder Singh from IT for Change, and Dr. Mahesh Uppal from ComFirst (India) Private Limited.

To kick off the webinar, Smitha Krishna Prasad of the Centre for Communication Governance at the National Law University presented an overview of the draft policy, following which the speakers shared their perspectives on the draft policy. Towards the end of the webinar, speakers answered questions from the participants in a lively and interactive Q&A session.

Some of the key issues discussed were on the Continue reading

How Istio, NSX Service Mesh and NSX Data Center Fit Together

This is the year of the service mesh. Service mesh solutions like Istio are popping up everywhere faster than you can say Kubernetes. Yet, with the exponential growth in interest also comes confusion. These are a few of the questions I hear out there:

  1. Where is the overlap between NSX service mesh (NSX-SM) with NSX-Datacenter (NSX-DC)?
  2. Is there synergy between the NSX-DC and Istio?
  3. Can service mesh be considered networking at all?

These are all excellent and valid questions. I will try to answer them at the end of the post, but to get there let’s first understand what each solution is trying to achieve and place both on the OSI layer to bring more clarity to this topic.

*Note – I focused this post on NSX-DC and Istio, to prevent confusion, Istio is an open source service mesh project, while NSX-SM is a VMware service delivering enterprise-grade service mesh, while it is built on top of Istio, it brings extensive capabilities beyond those that are offered by the Istio Open Source project.

 

Before we start, in a nutshell, what is Istio?

Istio (https://istio.io/) Is an Open Source service mesh project led by Google that addresses Continue reading
