A bumper crop of ten links today since I’ve been distracted with Interop Las Vegas where I presenting sessions & meeting with vendors. Then I flew to New York to perform some analyst work with investment/fund manager types.
The Ethernet Switching Landscape // Speaker Deck – The deck that Ethan Banks used at Interop Las Vegas 2014 for “Ethernet Switch Landscape” presentation. Learned a lot and recommended reading.
In this 2 hour presentation, I discussed the new technologies making Ethernet switches more important that simply “speeds and feeds.” After the technology discussion, I walked through the key points of 17 different Ethernet switch vendors, explaining their unique market positioning and value propositions.
Future of WAN. Why WAN When You Can Internet // Speaker Deck – Speaking of Interop presentations, here is my deck from “Future of WAN” at Interop Las Vegas 2014 where I put forward ideas about Internet replacing the traditional dedicated WAN and then back it up with some assertions about new protocols that will mean the end of WAN acceleration, IDS, load balancing and other technologies
The market is converging on HTTP and SSH as protocols. Future versions of HTTP/2 (presaged by QUIC/SPDY and others, and Microsoft SMB3 protocols means that encryption is the default. WAN Optimisation, IDS, Transparent Caching and VPNs will become problems. In fact, a security risk.
The Ultimate Guide to Solving iOS Battery Drain — Overthought – Useful checklist for the people in your life who treat you like tech support.
I worked on the Genius Bar for almost two years, and the most difficult issue to solve was short battery life. It was extremely difficult to pinpoint the exact reason why someone’s battery was draining.
I made it my mission to discover the specific reasons for iOS battery drainage. This article is a product of my years of research and anecdotal evidence I gathered in the hundreds of Genius Bar appointments I took during my time as a Genius and iOS technician, as well as testing on my personal devices and the devices of my friends.
An End To The Traditional Analysis Model? More Analysts Go To The Vendor Side – Forbes – Ben Kepes hihglighting that analysts are becoming increasingly confused with PR & Marketing. With many top name analysts leaving for vendors, the industry might be ripe for change.
It seems to me that the artificial divide between AR and PR is increasingly becoming a false one – some of the best tech journalists write insightful analysis that is up there with the best (good examples include Jack Clark at The Register and Alex Williams, formerly of TechCrunch). At the same time some of the best traditional analysts have a journalistic-like cadence towards publishing (case in point Holger Mueller of Constellation Research and Rene Buest at Crisp Research). As such trying to keep these two groups apart is kind of nonsensical.
This document defines the NSA (No Secrecy Afforded) certificate extension appropriate for use in certain PKIX (X.509 Pubic Key Certificates) digital certificates. Historically, clients and servers strived to maintain the privacy of their keys; however, the secrecy of their private keys cannot always be maintained. In certain circumstances, a client or a server might feel that they will be compelled in the future to share their keys with a third party. Some clients and servers also have been compelled to share their keys and wish to indicate to relying parties upon certificate renewal that their keys have in fact been shared with a third party.
Software Takes Center Stage as Vello Systems Leads Industry’s First Open Source Optical (OSO) Effort – Vello Systems – Open Source Optical is roughly equivalent (but different) to Open Network Linux or Cumlus Linux but for the optical network space.
It is software interoperability among multiple optical solution vendors that makes OSO possible and breaks the existing model of expensive vendor-locked optical systems that dominate the market today. To this end OSO will provide and maintain community-supported open source software that will power a variety of merchant-optical systems from current and future OSO members. This Open Source code will reside on the consortium’s web site, www.opensourceoptical.org.
OUTAGES: They Suck, But Let’s Share the After-Action Reports – Packet Pushers Podcast – Andrew Gallo talks about his experiences of post-mortem after a major failure.
First, within our organizations, we should have a regular practice of after-incident evaluation and documentation for purposes of improving service availability. Investigations and findings should be open, honest, shared, and where appropriate, remediations implemented.
Show 185 – Vendor Product Management – Packet Pushers Podcast – This podcast with Omar Sultan has been very popular with regular listeners. I’ve received tweets & emails on how useful and thought provoking the show was. On that basis, I will be recommend it here. It is important to understand the vendor process.
How do vendors decide to make network products ? What is the process and thinking behind what happens inside the wall of the vendor ? Today, Greg vendor-product-mgmtis joined by Omar Sultan from Cisco to talk broadly about how vendors make big decisions. Omar is a long time Cisco veteran with years of product management experience and we talk openly about the complexity, challenges and process that goes into delivering the devices that power your network.
Get Comic Neue – Funny but at least it is a good alternative. And it’s free.
Comic Neue aspires to be the casual script choice for everyone including the typographically savvy.
The squashed, wonky, and weird glyphs of Comic Sans have been beaten into shape while maintaining the honesty that made Comic Sans so popular.
It’s perfect as a display face, for marking up comments, and writing passive aggressive office memos.
Interop: Will SDN Make Me Homeless? – Did a panel at Interop on SDN:
Ivan Pepelnjak, chief technical advisor at NIL data communications said the SDN is nothing new.
and I said
“We install technical debt in our network when we don’t do anything,” Ferro said. “SDN holds out the hope that networking can be refreshed and we can stop incurring technical debt.”
Good summary of the panel.
