How Pensando Redefines Networking with P4 DSC (SmartNIC) – Rolf Schaerer, Systems Engineer @ Pensando Systems
In this episode Rick and Melchior invited Rolf Schaerer from Pensando Systems and ask him all how Pensando redefines the Netwok Server Edge.
“A New Way of Thinking About Next-Gen Cloud Architectures” leveraging a custom, programmable P4 processor Pensanso refers to as Capri. Capri is optimized to execute a software stack delivering cloud, compute, network, storage, and security services at cloud scale. Capri is easily installed in any standard server via the Pensando Distributed Services Card (DSC). The DSC provides software-defined services at the server edge, eliminating an assortment of discrete appliances throughout the data center and simplifying IT operations.
pygnmi 10. Rapid and Reliable Network Testing with Pytest, Pygnmi, and OpenConfig
Hello my friend,
Talking to some our partners, they mentioned that they are extensively using the unit tests python libraries for the development of the software in Python. They are creating their applications in Django framework; therefore, they are using a built-in Django testing library, which is based on Python’s standard unittest. We start looking, how we can use that ourselves…

Can This Help with Automated Network Assurance?
What do we, network engineers, do to quickly check that our network devices are reachable? We do ping. However, is that really good enough to check that your devices are OK? The one could say: I don’t even use a ping for that, as I rely on my NMS. This is also a good answer. In the same time, though, the vast majority of the NMS doesn’t contain all the details of network devices configuration and their operational data: e.g. all the details of OSPF and Continue reading
Crystal Notes: Enums
Enums group a related number of values and store the values internally as integers. Enums are good to use when the number of values are not too big. Considerations Enums are a type safe alternative to Symbols. It is recommended to use Enums whenever possible and only use Symbols for an...continue reading
Crystal Notes: Types
Strings Strings in Crystal are are declared with double quotes (""). Strings are stored as as sequence of UTF-8 encoded characters. Strings are immutable. Symbols Symbols in Crystal are declared by prefixing a colon (:) to a variable. Every instance of a Symbol is the same...continue reading

LISP – OMP – BGP EVPN Interoperability – Part IV: BGP EVPN IP Prefix Route (Type 5)
Introduction
Figure 3-1 shows the Overlay Network Control-Plane interaction. Edge-xTR-11 registers reachability information (IP address and location) of EP1 to MapSrv-22. MapSrv-22 stores the information into the Mapping database and then installs it to RIB. Then MapSrv-22 exports the information to the BGP process and sends BGP Update using VPNv4 address format to Border-PxTR-13. Border-PxTR-13 imports NLRI into BRIB and RIB. Then it sends BGP Update to the local SD-WAN edge device vEdge-1. After importing the received information into BRIB and RIB, vEdge-1 exports the information to the OMP process and advertises it over a DTLS connection to vSmart (SD-WAN Control-Plane node). vSmart, in turn, advertises information to remote SD-WAN device vEdge-2. After importing the received information into the RIB, vEdge-2 exports the information to the BGP process and sends BGP Update to Border-Leaf-13. Border-Leaf-13 installs the information into BRIB and RIB. Next, Border-Leaf-13 sends BGP Update message using EVPN route type 5 (IP Prefix Route) to its iBGP peer Spine-1 (BGP Route-Reflector) using auto-generated Route-Target 65030:10077. Spine-1 forwards the BGP Update to Leaf-1, which imports the information into L3VNI used with VRF NWKT and installs the route into the VRF NWKT RIB.

The Future of Work at Cloudflare
During Impact Week, we've shared how Cloudflare is providing tools for our customers to minimize their environmental impact as well as what we, as a company, are doing to help society at large. But some critical stakeholders we haven’t talked much about yet are Cloudflare's more than 2,000 employees: who build our services, support and educate our customers, keep our finances in order, work through difficult policy issues, and empower us to accomplish everything we have.
Over the last year and a half, we've all challenged a lot of the assumptions about what it means to "work." Prior to the start of the pandemic, Cloudflare was very much a work-from-office culture. And so when, on March 13, 2020, we closed all our offices and asked everyone to work from home, the two of us were extremely nervous.
And then something unexpected happened: a lot of things got better.
As a company, productivity increased — when measured by our success selling our products, our pace of shipping new products, and even things like the time it takes for our finance team to close our books.
Other day-to-day things got better, too. We noticed a marked increase in participation in Continue reading
The Cloudflare Startup Enterprise Plan: helping new startups bootstrap
Early in the life of most startups, there is a time of incredible hustle, creative problem solving, and making the impossible possible through out-of-the-box thinking and elbow grease. Grizzled veterans, who have lived through those days of running on coffee and shoestring budgets, look back on that time and fascinate the newcomers with war stories of back in the day, of adventures and first wins, when they kept the lights on by sheer force of will.
To help early stage startups get going, Cloudflare is giving away one year of the Startup Enterprise plan to all early stage startups in participating accelerator programs. That early stage time is special for product development, and entrepreneurs unlock worlds of possibilities when they have advanced tools on their hands, such as the power of the Cloudflare network.
What’s included in the Startup Enterprise plan?
In addition to the core offerings in the Pro and Business plans (e.g., CDN, DNS, WAF, custom SSL cert, 50 page rules), when founders sign up for the Startup Enterprise plan they’ll get special access to:
- Cloudflare Workers: 50 million requests / month.
- Deploy serverless code instantly across the globe to give it exceptional performance, reliability, Continue reading
