How the Lenca are Restoring the Past to Build their Future
The Internet has the potential to enable Indigenous communities to continue living on remote traditional lands without diminishing their access to services and information. The potential can go a long way towards closing the digital divide and offers new opportunities while preserving Indigenous culture.
In the ongoing debate about what difference the digital makes to the concept of Indigeneity itself, the voices of Indigenous people are what has been missing. It should be left up to community members to be caught up in this age of information and build the future on their own terms.
This is the story of Lenca people of Azacualpa, an Indigenous community of Yamaranguila in Intibucá, Honduras. In June 2017 they decided to start their relationship with technology by creating Radio Azacualpa, a radio station run by women, with the support of Cultural Survival’s Community Media Grants Project. It was a dream come true.
The radio tagline “La voz de las Mujeres” – the voice of women – says it all. “One of our goals as a radio station is to achieve recognition of our rights as women and to achieve equality,” explains Maria Santos, leader of the Azacualpa community.
In 2018, the Lenca decided Continue reading

Don’t Get Obsessed with REST API
REST API is the way of the world and all network devices should support it, right? Well, Ken Duda (Arista) disagreed with this idea during his Networking Field Day presentation, but unfortunately there wasn’t enough time to go into the details that would totally derail the presentation anyway.
Fixing that omission: should we have REST API on network devices or not?

Check out my prior below blogs here on VMware Network Virtualization blog on how NSX is leveraged in VMware Cloud on AWS to provide all the networking and security features. These prior blogs provide a foundation that this blog post builds on. In this blog post I discuss how AWS Direct Connect can be leveraged with VMware Cloud on AWS to provide high bandwidth, low latency connectivity to a SDDC deployed in VMware Cloud on AWS. This is one of my favorite features as it provides high bandwidth, low latency connectivity from on-prem directly into the customer’s VMware Cloud on AWS VPC enabling better and consistent connectivity/performance while also enabling live migration/vMotion from on-prem to cloud! I want to to thank my colleague, Venky Deshpande, who helped with some of the details in this post. Continue reading

Why and how to deploy Voyager
In Part I of this blog series, “What is the open packet optical switch, Voyager?”, we discussed the challenges and remedies for providing additional bandwidth for intra and inter data center connections. DWDM is a powerful technology that provides hundreds of gigabits of bandwidth over hundreds or thousands of kilometers using just a fiber pair. We also reviewed some information about DWDM networks and transponder functionality. Voyager provides all the functionality of Cumulus Linux running on a Broadcom Tomahawk based switch and integrates the transponders into the switch itself, all in 1RU. This makes it the first open and fully integrated box operating at DWDM, Layer 2 and Layer 3 in 1RU, making it extremely flexible.
Incorporating routing, switching and DWDM in one node could mean fewer boxes needed for the network, since DWDM functionality could be incorporated directly into border leafs. Because it runs Cumulus Linux (CL), all CL data center functionality, such as VXLAN Routing with EVPN, is also supported. For example, a pair of Voyager nodes can be used as VXLAN routing centralized routers with EVPN, hosting VXLAN VTEPs, running MLAG, and provide the long distance DWDM connectivity all in one box!
Voyager also Continue reading
ONOS traffic analytics
Mininet and onos.py workflow describes how to run ONOS using the Mininet network emulator. Mininet allows virtual networks to be quickly constructed and is a simple way to experiment with ONOS. In addition, Mininet flow analytics describes how to enable industry standard sFlow streaming telemetry in Mininet, proving a simple way monitor traffic in the ONOS controlled network.
For example, the following command creates a Mininet network, controlled by ONOS, and monitored using sFlow:
sudo mn --custom ~/onos/tools/dev/mininet/onos.py,sflow-rt/extras/sflow.py \The screen capture above shows the network topology in the ONOS web user interface.
--link tc,bw=10 --controller onos,1 --topo tree,2,2
In this case, the traffic was created by the following Mininet command:
