If you’ve been in networking for a few years, and already have acquired the traditional network certifications, it may be time to expand your horizons with certificates in specialized areas.
The vendor integrated SD-WAN, application acceleration, visibility, and security in a single device and says its SD-WAN now has more than 1,000 customers.
Five years ago when Google published The Datacenter as a Computer: Designing Warehouse-Scale Machines it was a manifesto declaring the world of computing had changed forever. Hop aboard or be left behind at the station. Since then the world has chosen to ride along with Google.
The world is still changing, so Google published a new edition: The Datacenter as a Computer: Designing Warehouse-Scale Machines, Third Edition.
What's different?
The third edition reflects four years of advancements since the previous edition and nearly doubles the number of pictures and figures. New topics range from additional workloads like video streaming, machine learning, and public cloud to specialized silicon accelerators, storage and network building blocks, and a revised discussion of data center power and cooling, and uptime. Further discussions of emerging trends and opportunities ensure that this revised edition will remain an essential resource for educators and professionals working on the next generation of WSCs.
The abstract:
This book describes warehouse-scale computers (WSCs), the computing platforms that power cloud computing and all the great web services we use every day. It discusses how these new systems treat the datacenter itself as one massive computer designed at warehouse scale, with hardware and Continue reading
Government officials want to prevent German telecom operators from using equipment from Chinese firms to construct their 5G networks. This would be similar to moves made by the U.S. and Australia.
As we approach the holiday buying season, excitement is building for all the new IoT gadgets – “smart” everything for the home, fitness/health trackers and a plethora of connected children’s toys. But this excitement should come with a giant asterisk:
* Are these products safe?
We’ve all seen the horror stories – hacked baby monitors, vulnerable door locks, robot vacuums turned into roving surveillance devices and connected toys pulled from shelves.
Clearly these gadgets need further inspection. This week the Internet Society has joined with Consumers International and Mozilla to advocate for a set of five minimum security and privacy standards IoT manufacturers should follow to improve the safety of their products. Mozilla has incorporated these into their evaluation of 70 products in the latest version of Privacy Not Included, their holiday IoT buyer’s guide. More detailed explanations of the guide and evaluation criteria are also available.
These minimum guidelines are great start to improve IoT security and privacy. They are a subset of our IoT Trust Framework, which comprehensively addresses key security, privacy and lifecycle principles that should be incorporated into IoT offerings. Manufacturers can use this list of principles to practice “trust by design,” resellers can Continue reading
This new Research Brief from AvidThink is aimed at providing enterprises and service providers with a view of the challenges in modern networking, and detailed strategies on how to overcome them by laying the right foundation for network automation.
We’ve had a lot going on behind the scenes at Network Collective. In this episode we give a little peak behind the curtain at what’s been going on with us and share some of the ways we’re modifying the show in response to how you all are consuming it.

If it’s the SC18 supercomputing conference, then there must be lists. …
Moving Graph Analytics Testing On Supercomputers Forward was written by Jeffrey Burt at .
The company’s 14th release of its flagship Cloud Data Management platform automates and protects applications across data centers and clouds. “All the nerd nobs have been automated,” said Chris Wahl, chief technologist at Rubrik.
The Internet Society participated in a Routing Security Workshop that was held during the Internet2 Technology Exchange 2018 on 15 October 2018 in Orlando, United States. The research and education networking community has been one of the key targets of the MANRS initiative that is promoting adoption of best practices to reduce threats to the global routing system, and this community workshop followed on from a previous engagement we had with Internet2 and a number of other R&E networks in the US earlier in the year.
Internet2 interconnects R&E institutes across the United States in conjunction with regional and state networks, so we see them as a key partner in raising awareness of the routing security issues, as well as encouraging the adoption of the four MANRS principles. Indeed, one of the aims of MANRS is for network operator communities to take ownership of this process by generating awareness and disseminating best practices, along with making recommendations for improvement. So this workshop was a fantastic step in this direction.
Another positive step was Internet2 formally becoming a MANRS participant shortly before the workshop, follow in the footsteps of ESnet, CAAREN, KanREN, George Washington University, Indiana University, and DePaul University. WiscNet Continue reading

Branch office traffic has changed due to the growing use of SaaS, video, and voice apps. Sites need flexible bandwidth, traffic segmentation, and load balancing. Multiple network links can help.
One of my readers sent me this question:
It would be nice to have a blog post or a webinar describing how to implement container networking in case when: (A) application does not tolerate NAT (telco, e.g. due to SCTP), (B) no DNS / FQDN, is used to find the peer element and (C) bandwidth requirements may be tough.
The only thing I could point him to is the Advanced Docker Networking part of Docker Networking Fundamentals webinar (available with free subscription) where macvlan and ipvlan are described.

Ah, unikernels. Small size, fast booting, tiny attack surface, resource efficient, hard to deploy on existing cloud platforms, and undebuggable in production. There’s no shortage of strong claims on both sides of the fence.
See for example:
In today’s paper choice, Williams et al. give us an intriguing new option in the design space: running unikernels as processes. Yes, that’s initially confusing to get your head around! That means you still have a full-fat OS underneath the process, and you don’t get to take advantage of the strong isolation afforded by VMs. But through a clever use of seccomp, unikernels as processes still have strong isolation as well as increased throughput, reduced startup time, and increased memory density. Most importantly though, with unikernels as processes we can reuse standard infrastructure and tools:
We believe that running unikernels as processes is an important step towards running them in production, because, as processes, they can Continue reading
