Observability in Data Center Networks
Observability in Data Center Networks: In this session, you’ll learn how the sFlow protocol provides broad visibility in modern data center environments as they migrate to highly meshed topologies. Our data center workloads are shifting to take advantage of higher speeds and bandwidth, so visibility to east-west traffic within the data center is becoming more important. Join Peter Phaal—one of the inventors of sFlow—and Joe Reves from SolarWinds product management as they discuss how sFlow differs from other flow instrumentation to deliver visibility in the switching fabric.THWACKcamp is SolarWinds’ free, annual, worldwide virtual IT learning event connecting thousands of skilled IT professionals with industry experts and SolarWinds technical staff. This video was one of the sessions.

The TLS Post-Quantum Experiment
In June, we announced a wide-scale post-quantum experiment with Google. We implemented two post-quantum (i.e., not yet known to be broken by quantum computers) key exchanges, integrated them into our TLS stack and deployed the implementation on our edge servers and in Chrome Canary clients. The goal of the experiment was to evaluate the performance and feasibility of deployment in TLS of two post-quantum key agreement ciphers.
In our previous blog post on post-quantum cryptography, we described differences between those two ciphers in detail. In case you didn’t have a chance to read it, we include a quick recap here. One characteristic of post-quantum key exchange algorithms is that the public keys are much larger than those used by "classical" algorithms. This will have an impact on the duration of the TLS handshake. For our experiment, we chose two algorithms: isogeny-based SIKE and lattice-based HRSS. The former has short key sizes (~330 bytes) but has a high computational cost; the latter has larger key sizes (~1100 bytes), but is a few orders of magnitude faster.
During NIST’s Second PQC Standardization Conference, Nick Sullivan presented our approach to this experiment and some initial results. Quite accurately, Continue reading
Worth Reading: How Complex Systems Fail
I don’t remember who pointed me to the excellent How Complex Systems Fail document. It’s almost like RFC1925 – I could quote it all day long, and anyone dealing with large mission-critical distributed systems (hint: networks) should read it once a day ;))
Enjoy!
The ease and importance of scaling in the enterprise
Networks are growing, and growing fast. As enterprises adopt IoT and mobile clients, VPN technologies, virtual machines (VMs), and massively distributed compute and storage, the number of devices—as well as the amount of data being transported over their networks—is rising at an explosive rate. It’s becoming apparent that traditional, manual ways of provisioning don’t scale. Something new needs to be used, and for that, we look toward hyperscalers; companies like Google, Amazon and Microsoft, who’ve been dealing with huge networks almost since the very beginning.
The traditional approach to IT operations has been focused on one server or container at a time. Any attempt at management at scale frequently comes with being locked into a single vendor’s infrastructure and technologies. Unfortunately, today’s enterprises are finding that even the expensive, proprietary management solutions provided by the vendors who have long supported traditional IT practices simply cannot scale, especially when you consider the rapid growth of containerization and VMs that enterprises are now dealing with.
In this blog post, I’ll take a look at how an organization can use open, scalable network technologies—those first created or adopted by the aforementioned hyperscalers—to reduce growing pains. These issues are increasingly relevant as new Continue reading
