AI Redefines Performance Requirements At The Edge
In a broad sense, the history of computing is the constant search for the ideal system architecture. Over the last few decades system architects have continually shifted back and forth from centralized configurations where computational resources are located far from the user to distributed architectures where processing resources were located closer to the individual user.
Early systems used a highly centralized model to deliver increased computational power and storage capabilities to users spread across the enterprise. During the 1980s and 1990s, those centralized architectures gave way to the rise of low cost PCs and the emergence of LANs and then …

Autumn 2018 Network Automation Course Starts on September 18th
When the Spring 2018 Building Network Automation Solutions online course started, we didn’t know whether we’d run another course in 2018, so we offered engineers who wanted to get an early start Believer price.
The wait is over: the autumn 2018 course starts on September 18th. The schedule of the live sessions is already online, and we also have the first guest speakers. We’ll announce them in early June at which time you will no longer be able to get the Enthusiast price, so register ASAP.
Photo-realistic single image super-resolution using a generative adversarial network
Photo-realistic single image super-resolution using a generative adversarial network Ledig et al., arXiv’16
Today’s paper choice also addresses an image-to-image translation problem, but here we’re interested in one specific challenge: super-resolution. In super-resolution we take as input a low resolution image like this:
And produce as output an estimation of a higher-resolution up-scaled version:
For the example above, here’s the ground truth hi-resolution image from which the low-res input was initially generated:
Especially challenging of course, is to recover / generate realistic looking finer texture details when super-resolving at large upscaling factors. (Look at the detail around the hat band and neckline in the above figures for example).
In this paper, we present SRGAN, a generative adversarial network (GAN) for image super-resolution (SR). To our knowledge, it is the first framework capable of inferring photo-realistic natural images for 4x upscaling factors.
In a mean-opinion score test, the scores obtained by SRGAN are closer to those of the original high-resolution images than those obtained by any other state-of-the-art method.
Here’s an example of the fine-detail SRGAN can create, even when upscaling by a factor of 4. Note how close it is to the original.

How to manage access in a web-scale data center
One of the consistent questions that arises during the web-scale transition is the impact of managed access to networking infrastructure. How do we take traditional management techniques and adapt them to the new operational paradigm of web-scale networking, where automation drives the majority of changes and the infrastructure is treated as a holistic entity rather than node-by-node?
Local privileges
In the most basic way, we can migrate existing workflows to the new paradigm. Though inefficient, the old way of doing things still works with the new web-scale paradigm. The easiest way to do this is to restrict access to your switches using local privileges. In Linux, users are controlled using the adduser command, and the permissions for that user are controlled using the chmod commands.
A list of all users is stored in the /etc/passwd folder of Linux:
cumulus@leaf02:~$ cat /etc/passwd root:x:0:0:root:/root:/bin/bash daemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin bin:x:2:2:bin:/bin:/usr/sbin/nologin sys:x:3:3:sys:/dev:/usr/sbin/nologin sync:x:4:65534:sync:/bin:/bin/sync games:x:5:60:games:/usr/games:/usr/sbin/nologin man:x:6:12:man:/var/cache/man:/usr/sbin/nologin lp:x:7:7:lp:/var/spool/lpd:/usr/sbin/nologin mail:x:8:8:mail:/var/mail:/usr/sbin/nologin news:x:9:9:news:/var/spool/news:/usr/sbin/nologin uucp:x:10:10:uucp:/var/spool/uucp:/usr/sbin/nologin proxy:x:13:13:proxy:/bin:/usr/sbin/nologin www-data:x:33:33:www-data:/var/www:/usr/sbin/nologin backup:x:34:34:backup:/var/backups:/usr/sbin/nologin list:x:38:38:Mailing List Manager:/var/list:/usr/sbin/nologin irc:x:39:39:ircd:/var/run/ircd:/usr/sbin/nologin gnats:x:41:41:Gnats Bug-Reporting System (admin):/var/lib/gnats:/usr/sbin/nologin nobody:x:65534:65534:nobody:/nonexistent:/usr/sbin/nologin systemd-timesync:x:100:103:systemd Time Synchronization,,,:/run/systemd:/bin/false systemd-network:x:101:104:systemd Network Management,,,:/run/systemd/netif:/bin/false systemd-resolve:x:102:105:systemd Resolver,,,:/run/systemd/resolve:/bin/false systemd-bus-proxy:x:103:106:systemd Bus Proxy,,,:/run/systemd:/bin/false frr:x:104:109:Frr routing suite,,,:/var/run/frr/:/bin/false ntp:x:105:110::/home/ntp:/bin/false uuidd:x:106:111::/run/uuidd:/bin/false messagebus:x:107:112::/var/run/dbus:/bin/false sshd:x:108:65534::/var/run/sshd:/usr/sbin/nologin snmp:x:109:114::/var/lib/snmp:/usr/sbin/nologin dnsmasq:x:110:65534:dnsmasq,,,:/var/lib/misc:/bin/false _lldpd:x:111:115::/var/run/lldpd:/bin/false cumulus:x:1000:1000:cumulus,,,:/home/cumulus:/bin/bash
