In Network Break 43 we dig into Cisco’s acquisition of OpenDNS and get sidetracked into a discussion of online anonymity and privacy. We also check out Cisco’s recently announced IoT system for resellers. We look at new features in the Lithium release of the OpenDaylight controller, including Network Intent Composition, and discuss the momentum of open source in the networking industry.
An alarming Gartner headline about IT spending sucks us in, but the news turns out not to be so alarming. Last but not least, we chew on Amazon’s s2n, a stripped-down TLS implementation that Amazon is releasing as an open-source project. See the full story links below.

What’s New In Lithium – OpenDaylight
Global IT Spending To Decline Due To U.S. Dollar Strength
“Within the data center systems segment, storage and network markets are both expected to see weaker growth in U.S. dollar terms as a result of the appreciation of the U.S. dollar. Enterprise budgets for data center systems in local spending are expected to remain stable for the year, with users expected to extend life cycles and defer replacements as a means of offsetting the price increases. The overall near-term data center weakness is slightly offset by a more positive outlook for the server market. The server market is benefiting from a stronger-than-expected mainframe refresh cycle, as well as increased expectations for hyperscale spending.”
Amazon’s s2n: An Open-Source TLS Implementation
“s2n avoids implementing rarely used options and extensions, and today is just more than 6,000 lines of code. As a result of this, we’ve found that it is easier to review s2n; we have already completed three external security evaluations and penetration tests on s2n, a practice we will be continuing.”
