Cumulus Networks updates its network-centric Linux distribution

The Linux distribution ecosystem is pretty set, with Red Hat and Canonical in the leadership positions, followed closely by SuSe and home brews from the likes of IBM and other major vendors. Even Microsoft has its own distro for Azure users.And then there is Cumulus Networks, which specializes in networking software. It just released Cumulus Linux 4.0 and NetQ 2.4, its cloud network deployment and management console. With this release, Cumulus is claiming its Linux is its most stable and reliable software stack yet and NetQ is the most comprehensive end-to-end network automation product.To read this article in full, please click here

IoT sensors must have two radios for efficiency

For the Internet of Things to become ubiquitous, many believe that inefficiencies in the powering of sensors and radios has got to be eliminated. Battery chemistry just isn’t good enough, and it’s simply too expensive to continually perform truck-rolls, for example, whenever batteries need changing out. In many cases, solar battery-top-ups aren’t the solution because that, usually-fixed, technology isn’t particularly suited to mobile, or impromptu, ad hoc networks.Consequently, there’s a dash going on to try to find either better chemistries that allow longer battery life or more efficient chips and electronics that just sip electricity. An angle of thought being followed is to wake-up network radios only when they need to transmit a burst of data. Universities say they are making significant progress in this area.To read this article in full, please click here

KubeCon 2019 Day 2 Summary

Keynotes

This morning’s keynotes were, in my opinion, better than yesterday’s morning keynotes. (I missed the closing keynotes yesterday due to customer meetings and calls.) Only a couple of keynotes really stuck out. Vicki Cheung provided some useful suggestions for tools that are helping to “close the gap” on user experience, and there was an interesting (but a bit overly long) session with a live demo on running a 5G mobile core on Kubernetes.

Running Large-Scale Stateful Workloads

Due to some power outages at the conference venue resulting from rain in San Diego, the Prometheus session I had planned to attend got moved to a different time. As a result, I sat in this session by Lyft instead. The topic was about running large-scale stateful workloads, but the content was really about a custom solution Lyft built (called Flyte) that leveraged CRDs and custom controllers to help manage stateful workloads. While it’s awesome that companies like Lyft can extend Kubernetes to address their specific needs, this session isn’t helpful to more “ordinary” companies that are trying to figure out how to run their stateful workloads on Kubernetes. I’d really like the CNCF and the conference committee to try Continue reading

BrandPost: What Palo Alto Networks Won’t Tell You About Its New SASE Service

It has been a long time since I shared an office with Nir Zuk, the co-founder and CTO of Palo Alto Networks (PAN). Back in 1998, at Check Point’s office in San Francisco, it was early days for the network security company co-founded by Gil Shwed, Marius Nacht, and me. Since then, Nir launched PAN, which became a global leader in network security. I was honored to support Nir and the PAN team early in their journey.Last week, our paths converged again. This time, we shared a vision for the future of networking and security. On the stage of PAN’s annual event, Nir presented PAN’s vision of a converged cloud-based architecture that will displace the legacy appliance stack of today. Nir did a great job advocating for the convergence of the numerous point solutions piled in IT departments everywhere.To read this article in full, please click here

Even faster connection establishment with QUIC 0-RTT resumption

One of the more interesting features introduced by TLS 1.3, the latest revision of the TLS protocol, was the so called “zero roundtrip time connection resumption”, a mode of operation that allows a client to start sending application data, such as HTTP requests, without having to wait for the TLS handshake to complete, thus reducing the latency penalty incurred in establishing a new connection.

The basic idea behind 0-RTT connection resumption is that if the client and server had previously established a TLS connection between each other, they can use information cached from that session to establish a new one without having to negotiate the connection’s parameters from scratch. Notably this allows the client to compute the private encryption keys required to protect application data before even talking to the server.

However, in the case of TLS, “zero roundtrip” only refers to the TLS handshake itself: the client and server are still required to first establish a TCP connection in order to be able to exchange TLS data.

Zero means zero

QUIC goes a step further, and allows clients to send application data in the very first roundtrip of the connection, without requiring any other handshake to be Continue reading
