Good day,
The same question arises often about how to leverage DCNM to deploy a VXLAN EVPN Multi-site between traditional Data Centers. To clarify, DCNM can definitively help interconnecting two or multiple Classical Ethernet-based DC networks, in a short time.
As a reminder (post 37) , VXLAN EVPN Multi-site overlay is initiated from the Border Gateway nodes (BGW). The BGW function can run in two different modes; either in Anycast BGW mode (Up to 6 BGW devices per site), traditionally deployed to interconnect VXLAN EVPN based fabrics, or in vPC BGW mode (up to 2 BGW per site), essentially designed to interconnect traditional data centers, but not limited to. vPC BGW can be leveraged to interconnect multiple VXLAN EVPN fabrics from which Endpoints can be locally dual- attached at layer 2. Several designations are used to describe the Classic Ethernet-based data center networks such as Traditional or legacy data center network. All these terms mean that these network are non VXLAN EVPN-based fabrics. The vPC BGW node is agnostic about data center network types, models or switches that construct the data center infrastructure, as long as it offers Layer 2 (dot1Q) connectivity for layer 2 extension, and if Continue reading

Oracle is an Organization Member of the Internet Society. We welcome this guest post announcing a new tool that complements our work to improve the security of the Internet’s routing infrastructure.
We are proud to announce the launch of the IXP Filter Check, which is designed to improve Internet routing security by monitoring route filtering at Internet Exchange Points (IXPs). Here we describe the origin of this project, how it works, and what it hopes to achieve.
Background
Last year, Oracle started partnering with the Internet Society to explore ways to make the Internet safer and more secure for our enterprise customers and users. Businesses – banks, insurance companies, pharmaceutical firms – as well as non-profit organizations and governments continue to turn to Internet-facing assets as key components of their critical infrastructure. Market research firm IDC estimates that 55.9 billion devices will be online by 2025. We believe it is incumbent upon us, as trusted partners and suppliers, to help make the global Internet as safe as possible.
Securing trust-based Internet routing is one such security challenge. Despite decades of research and engineering on the topic, securing Internet routing remains a notoriously difficult task. The challenge is evidenced by the fact that nearly every month there is another major story of a Continue reading

When I first met Cumulus Networks engineers (during NFD9) their focus on simplifying switch configurations totally delighted me (video).
After solving the BGP configuration challenge (could you imagine configuring BGP in a leaf-and-spine fabric with just a few commands in 2015), they did the same thing with EVPN configuration, where they decided to implement the simplest possible design (EBGP-only fabric running EBGP EVPN sessions on leaf-to-spine links), resulting in another round of configuration simplicity.

What do people actually do when they do ‘exploratory data analysis’ (EDA)? This 2018 paper reports on the findings from interviews with 30 professional data analysts to see what they get up to in practice. The only caveat to the results is that the interviews were conducted in 2015, and this is a fast-moving space. The essence of what and why is probably still the same, but the tools involved have evolved.
Exploration here is defined as “open-ended information analysis,” which doesn’t require a precisely stated goal. It comes after data ingestion, wrangling and profiling (i.e., when you have the data in a good enough state to ask question of it). The authors place it within the overall analysis process like this:
That looks a lot more waterfall-like than my experience of reality though. I’d expect to see lots of iterations between explore and model, and possibly report as well.
The guidance given to survey participants when asking about EDA is as follows:
EDA is an approach to analyzing data, usually undertaken at the beginning of an analysis, to Continue reading
