Community Networks: Improving Connectivity for All in Haiti
The COVID-19 pandemic reminds us of the historic transition brought about by the Internet. Its place is real in our lives today and tomorrow. Celebrate, pray, play, study, work, express yourself … these verbs have been conjugated thousands of times everywhere thanks to the Internet. In Haiti, many suffer from the glaring inequality between Internet access in rural and urban areas. It is clear that tackling these problems comes down to building a safe path towards decentralization of Internet infrastructure here.
The mission of the Internet Society Haiti Chapter (ISOC Haiti) is to promote, on Haitian territory and for the benefit of all, the conditions and tools conducive to the development of an information and knowledge society – respectful of Haitian culture and values. Since 1804, our nation has raised its voice for freedom and equality so that every person may live free and in dignity, while banishing Black slavery on our land. Our motto, ‘’unity is strength,’’ reminds us that together we can achieve unimaginable things to change this nation. ISOC Haiti is aware of the challenges and believes it is time for a sustainable plan of action – and not for speech.

Network Automation Products for Brownfield Deployments
Got this question from one of my long-time readers:
I am looking for commercial SDN solutions that can be deployed on top of brownfield networks built with traditional technologies (VPC/MLAG, STP, HSRP) on lower-cost networking gear, where a single API call could create a network-wide VLAN, or apply that VLAN to a set of ports. Gluware is one product aimed at this market. Are there others?
The two other solutions that come to mind are Apstra AOS and Cisco NSO. However, you probably won’t find a simple solution that would do what you want to do without heavy customization as every network tends to be a unique snowflake.

Extend Your Fortinet FortiManager to Kubernetes
Companies are leveraging the power of Kubernetes to accelerate the delivery of resilient and scalable applications to meet the pace of business. These applications are highly dynamic, making it operationally challenging to securely connect to databases or other resources protected behind firewalls.
Visibility into Kubernetes Infrastructure is Essential
Lack of visibility has compliance implications. Like any on-premises or cloud-based networked services, Kubernetes production containers must address both organizational and regulatory security requirements. If compliance teams can’t trace the history of incidents across the entire infrastructure, they can’t adequately satisfy their audit requirements. To enable the successful transition of Kubernetes pilot projects to enterprise-wide application rollouts, companies must be able to extend their existing enterprise security architecture into the Kubernetes environment.
In response, Fortinet and Tigera jointly developed a suite of Calico Enterprise solutions for the Fortinet Security Fabric that deliver both north-south and east-west visibility and help ensure consistent control, security, and compliance. Key among these integrations is the FortiManager Calico Kubernetes Controller, which enables Kubernetes cluster management from the FortiManager centralized management platform in the Fortinet Fabric Management Center.

Broadcom Mirror on Drop (MoD)
Broadcom BroadView+ Root Cause Analysis with Mirror-on-Drop (MOD) and Inband Flow Analyzer (IFA) from Gestalt IT on Vimeo.
The recently published sFlow Dropped Packet Notification Structures specification adds drop notifications to industry standard sFlow telemetry export, complementing the existing push based counter and packet sampling measurements. The inclusion of drop monitoring in sFlow will allow the benefits of MOD to be fully realized, ensuring consistent end-to-end visibility into dropped packets across multiple vendors and network operating systems.
Using Advanced Telemetry to Correlate GPU and Network Performance Issues demonstrates how packet drop notifications from NVIDA Mellanox switches forms part of an integrated sFlow telemetry stream that provides the system wide observability needed to drive automation.
MOD instrumentation on Broadcom based switches provides the foundation needed for network vendors to integrate the Continue reading
Using Advanced Telemetry to Correlate GPU and Network Performance Issues
The image above was captured from the recent talk Using Advanced Telemetry to Correlate GPU and Network Performance Issues [A21870] presented at the NVIDIA GTC conference. The talk includes a demonstration of monitoring a high performance GPU compute cluster in real-time. The real-time dashboard provides an up to the second view of key performance metrics for the cluster.
This diagram shows the elements of the GPU compute cluster that was demonstrated. Cumulus Linux running on the switches reduces operational complexity by allowing you to run the same Linux operating system on the network devices as is run on the compute servers. sFlow telemetry is generated by the open source Host sFlow agent that runs on the servers and the switches, using standard Linux APIs to enable instrumentation and gather measurements. On switches, the measurements are offloaded to the ASIC to provide line rate monitoring.
Telemetry from all the switches and servers in the cluster is streamed to an sFlow-RT analyzer, which builds a real-time view of performance that can be used to drive operational dashboards and automation.
The Real-time GPU and network telemetry dashboard combines measurements from all the devices to provide view of cluster performance. Each of the three Continue reading

The Internet of Food
This abridged article by Francisca Hector was originally published in Tasty Bytes.
Arguably food is the most important item on the planet. The current food system; however, has many inefficiencies and food security continues to be a global challenge.
In addition to this, conscious consumption has reached new heights as consumers demand that their food is not only safe, nutritious, and affordable, but they also want to ensure that their food is ethically sourced and the harvesting and production processes reduce waste.
For many, there is the belief that the food system needs to be fundamentally disrupted. While there have been some attempts to use technology to make better decisions around food, these technologies are not widely available. Without widespread availability and adoption, the impact of any technology is hard to ascertain.
This and other concerns are what spurred the creation of The Internet Society Special Interest Group for the Internet of Food (SIG-IOF), which is a discussion room for next-gen Internet backbone standards for digital aspects of food. In short, that means that when food goes data, this group would like to facilitate the Internet standards for how that data is handled.
