- I finished the first draft of a chapter on QoS, which I am possibly going to turn into a 2-3 hour webinar with Ivan Pepelnjak to run in September 2017.
- I finished the first draft of a chapter on virtualized network functions (VNFs). Always hard to know how deeply to go into a topic in an introductory textbook. This ended up as a short chapter in this iteration, ~4,400 words introducing concepts of ASICs vs general-purpose CPUs, intent-driven networking, service function chaining, network service header, scale out, and automation. Second iteration might be longer, depending on what the editors and technical reviewers offer as feedback.
- I am quoted in Network World along with a bunch of other pundits about automation. NWW chokes your browser with so many ads that you won’t be able to read the article without clearing a couple of them away first. Which…I guess…is really the point of the article. Ad impressions. Too bad. Network World was my go-to dead-tree publication about 15 years ago. It arrived at my office weekly or so, and I looked forward to every issue. Rich, educational content and thorough industry coverage. Not so much anymore. Now NWW and similar publications are mostly SEO-driven ad-delivery machines. When I write for these pubs every now and then, I often have a hard time recognizing my original work after the web people get through with it. The media business has certainly changed. Reminder to myself to make sure my own company doesn’t drive off the audience with listicles, click-bait titles, popover ads, and so on…
- I offer a quote that will be printed on the back cover of the soon-coming Day One: Juniper Ambassadors Cookbook 2017. An interesting book covering mostly bleeding edge stuff in a recipe format. A useful tool that translates emerging techniques into a configuration reference with a healthy dose of explanation along the way.
- I’m working heavily on a 4 hour presentation for InteropITX’s Future Of Networking Summit. My focus this month has been on what I believe is a foundational topic–network modeling, specifically the work being done to create standardized models in YANG. I’ve watched a few hours of YouTube training videos and presentations on NETCONF and YANG, mostly from Tail-F, acquired by Cisco a while back.
- I had an hour plus conversation with a friend of mine regarding the efficacy of SDN for creating dynamic end-to-end storage paths in a converged IP fabric. Storage, depending on the protocol employed, requires a lossless path, something neither Ethernet nor IP guarantee. To create a lossless path, specific QoS guarantees must be put into place end-to-end between the host and the storage node. Can this be done with SDN? We’re going to do some digging and possibly generate a paper about the topic. SDN has been bad, arguably, about creating a toolbox that can be applied to any situation and better about creating specific point solutions that solve specific problems. Plus, variant hardware introduces complexity that abstractions might, to a point, resolve…but I’m not sure yet to what degree.
- Network Computing wrote a promo piece for InteropITX, and I’m mentioned as one of the speakers in the slideshow. Had no idea the piece was coming. Interesting in that the byline wasn’t written by me. Often, the authors of these sorts of pieces reach out and ask for some copy they can stick under your name. Not this time, but my friend Marcia wrote a description that I thought was interesting. Liked her choice of keyword “objective,” which is what I strive for.
