Learn about new tools to test your apps for compatibility and get expert advice on making sure your apps work in all network environments. iOS 9 and OS X 10.11 now support the latest TCP standards. Hear from the experts on TCP Fast Open and Explicit Congestion Notification, and find out how it benefits your apps." Being on this list you might not learn much from the talk, but I really appreciate a talk aimed at a wider (developer) audience which so clearly outlines the benefits of ECN, CoDel and TCP host opimization to reduce end-to-end experienced application communication latency. One of the major takeaways is that Apple is planning to by default enable ECN in iOS9 and OSX 10.11. This would mean hundreds of millions of devices will be using ECN in a few months. You can skip to 16 minutes into the talk if you're not interested in the new requirement for applications to support an environment where it's Internet access is IPv6 only behind NAT64+DNS64 (I'm myself super excited about this). Let's hope this brings a lot of buzz and requests towards device manufacturers to start supporting ECN marking and AQM. Apple is usually a good megaphone to bring attention to these kinds of issues... -- Mikael Abrahamsson email: swmike@swm.pp.se
