If your app loads critical resources over the network, it's relying on your user's mobile network connection to deliver an engaging experience. Network errors occur in 3 to 12% of app sessions depending on infrastructure reliability and user geography.
How much engagement are you losing in your app to network errors? Chances are, you don't know.
We didn't either, until we built a free tool that helps Android and iOS developers visualize and understand their mobile app's network utilization.
Our SDK helps you identify slowdowns caused by balky or too frequent network calls, so you can focus your development effort on optimizing the lowest-hanging fruit.
Modern app developers already heavily instrument their apps to identify UX impacting events: they measure and collect launch time, session length, crash rates, conversion events, and lots more, using a multitude of different metrics packages and services.
Web developers look at similar data. They also pay tons of attention to their resource waterfall, mapping their critical rendering path, and understanding which resource loads are synchronous, which are not, and which block rendering. JavaScript even exposes an API to collect waterfalls in the browser programmatically.
It's time to bring the same visibility Continue reading
How do we connect everyone, everywhere, to the Internet? What role do “community networks” play in helping connect more people? How can we best use wireless spectrum and what are the issues with that? How can satellites fit into the picture? And what is the state of satellite technology? And what about the role of “space lasers”?
All that and more was the subject of yesterday’s featured panel at the Technical Plenary at IETF 101 in London.
Organized by the Internet Architecture Board (IAB) and the Internet Research Task Force (IRTF), the panel was moderated by our Jane Coffin and included these speakers:

Comment connecter tout le monde, partout, à Internet? Quel rôle jouent les «réseaux communautaires» pour aider à connecter plus de gens? Comment pouvons-nous utiliser au mieux le spectre sans fil et quels sont les problèmes avec cela? Comment les satellites peuvent-ils s’intégrer dans l’image? Et quel est l’état de la technologie par satellite? Et qu’en est-il du rôle des “lasers spatiaux”?

Alex was trying to figure out how to use Catalyst 3850 switches and sent me this question:
Is MLAG an alternative to use rather than physically creating a switch stack?
Let’s start with some terminology.
Link Aggregation Group (LAG) is the ability to bond multiple Ethernet links into a single virtual link. LAG (as defined in 802.1ax standard) can be used between a pair of adjacent nodes. While that’s good enough if you need more bandwidth it doesn’t help if you want to increase redundancy of your solution by connecting your edge device to two switches while using all uplinks and avoiding the shortcomings of STP. Sounds a bit like trying to keep the cake while eating it.
Read more ...Dual-active Detection (DAD) is designed to prevent a split-brain scenario where both VSS supervisors become active in the event of a VSL link failure. It uses a separate (from the VSL link) secondary communication link to communicate the devices state.
When the VSL link fails the standby switch becomes active and the current active switch is informed of this over the DAD links and goes into recovery mode to stop a split-brain situation occurring.
Microsoft is working with Intel, Facebook, and Google to implement Project Cerberus security architecture. It plans to contribute the open hardware security specs to OCP.
A recurring topic at the Open Compute Project summit was the increase in east-west traffic within data centers. To cope with this traffic, Facebook innovated a distributed network system called the Fabric Aggregator.
We are pleased to announce that nominations for the 2018 Jonathan B. Postel Service Award are now open. Do you know someone who should be a recipient?
This annual award is presented to an individual or organization that has made outstanding contributions in service to the data communications community and places particular emphasis on those who have supported and enabled others.
Nominations are encouraged for individuals or teams of individuals from across the data communications industry around the world who are dedicated to the efforts of advancing the Internet for the benefit of everybody.
Past Postel award winners include kc claffy for her pioneering work on Internet measurement, Mahabir Pun for his key role in bringing the Internet to rural Nepal with the founding of the Nepal Wireless Networking Project, and Bob Braden and Joyce K. Reynolds for their stewardship of the RFC (Request for Comments) series.
The signature crystal globe and a USD 20,000 prize will be presented at the IETF 102 in Montreal, Canada (14 -20 July 2018) to the chosen candidate.
Nominations can be made either by self nomination or by third party: https://apps.internetsociety.org/form/postel-nominations
