It seems the latest buzzword coming from those analysts at Gartner is SASE (pronounced “sassy”), which stands for “Secure Access Service Edge.” Network World has published several articles recently to explain what SASE is (and perhaps isn’t). See Matt Conran’s The evolution to Secure Access Service Edge (SASE) is being driven by necessity as well as Zeus Kerravala’s article How SD-WAN is evolving into Secure Access Service Edge.To read this article in full, please click here
There are many broadband services Service Providers offer to their customers today. As a network engineer you need to know the most common services and their advantages, disadvantages, design characteristics and so on.
What is last mile and first mile ? This is an important telecommunication term which is used in all broadband communication methods. In this post, I will explain the term, differences and some detail about this term.
Juniper has enhanced its network and hybrid cloud management software by integrating further the AI technology it recently acquired from Mist and adding new features to its Contrail Enterprise Multicloud software.The company recently closed the agreement to buy wireless-gear-maker Mist for $405 million and promised to meld the Mist technology with Juniper’s. Mist is known for its cloud-managed artificial-intelligence-based wireless service called WiFi Assurance that measures performance and service-level metrics to make wireless networks more predictable and reliable, the company said.To read this article in full, please click here

MP-BGP (Multiprotocol BGP) is an extensions to BGP protocol. Standard BGP only supports IPv4 unicast address family, whereas MP-BGP supports more than 15 different BGP address families.
One of the most important thing about CCDE exam is security. We all think that it is secure, it is not cheatable. There is no CCDE dump. We all believe that. CCDE exam has been around for more than 10 years and there are still only less than 500 people in the world. It seems what we think about exam security is correct.
Today, there are many networking technologies which haven’t been widely deployed. And among them are Internet Multicast and IPv6 although these two protocols have many benefits .
BGP PIC Edge provides sub second convergence time in the case of edge link or node failure. BGP PIC is a useful for MPLS VPN service and can be provided by the Service provider as a value added service thus might provide additional revenue.
BFD is not a fast convergence mechanism. BFD stands for Bidirectional Forwarding Detection. It is an important tool for the IP layer but there is a confusion in the network community about it.
After publishing the Disaster Recovery Faking, Take Two blog post (you might want to read that one before proceeding) I was severely reprimanded by several people with ties to virtualization vendors for blaming virtualization consultants when it was obvious the firewall clusters stretched across two data centers caused the total data center meltdown.
Let’s chase that elephant out of the room first. When you drive too fast on an icy road and crash into a tree who do you blame?
The person who told you it’s perfectly OK to do so;
The tire manufacturer who advertised how safe their tires were?
The tires for failing to ignore the laws of physics;
Yourself for listening to bad advice
For whatever reason some people love to blame the tires ;)
Roopa Prabhu and Roopa’s hype man Pete Lumbis join Kernel of Truth host Brian O’Sullivan to discuss why open networking is not just whitebox, it’s so much more. Between the general advantages of this kind of architecture to the benefits of being backed by the Linux kernel and Linux community— open networking is a great option to have not just now but going forward. Learn how this open development community works together to the advantage of everyone, not just networking, and with companies of all sizes, including hyper-scale ones, improving things like the sanitation of code and so much more. As a special bonus you’ll also learn what to eat in the data center. Spoiler: the answer is nothing but Brian might have an opinion otherwise.

Brian O’Sullivan: Brian currently heads Product Management for Cumulus Linux. For 15 or so years he’s held software Product Management positions at Juniper Networks as well as other smaller companies. Once he saw the change that was happening in the networking space, he decided to join Cumulus Networks to Continue reading
I’m writing to the Internet Society community today with a notice that there is a key change to the Procedures for Selecting Trustees starting this year. This change reduces the duration of voting period from 28 to 14 days in the Internet Society Board of Trustees elections through which Chapters and Organization Members get to elect candidates to the Board.
If you read the 2019-2020 Elections Timetable carefully, you may notice that the Candidates Forum and the voting period are no longer done in parallel. As the below timeline shows, the 28-day period that used to be allocated for voting and the Candidates Forum is now split into two distinct sequential stages: the first 14 days is for the Candidates Forum and the second 14 days is for voting.
This decision was made for two reasons.
The first is to allow candidates to be heard fully before votes are cast. Upon examining the activity log of the last elections, we realized that some voters cast their ballots before the candidates had a chance to interact with the community. Voting before hearing what candidates have to say in the Candidates Forum is detrimental to the elections process as it encourages Continue reading
On Veterans Day, and every day, we give thanks to our veterans. We are fortunate to have Brent Salisbury, Siobhan Casey, and Johnny Gonzalez, as Docker colleagues who were in the United States Marine Corps Reserve, the United States Army Reserve, and the United States Marine Corps. Thank you all for your service, hard work, and dedication. As a thank you for their service, we’re profiling them on our blog.
Brent Salisbury, Software Alliance Engineer
Brent Salisbury was in the United States Marine Corps Reserve from 1996-2002. Now, he is a Software Alliance Engineer at Docker. You can follow him on Twitter @networkstatic.
What is your job?
Software Alliance Engineer.
How long have you worked at Docker?
4.5 years.
Is your current role one that you always intended on your career path?
Data Networking has been my passion since college. Working at Docker has afforded me the opportunity to help usher in a new software paradigm in what can be achieved in host networking and security versus the traditional proprietary hardware models of the past.
What is your advice for someone entering the field?
It may sound cliche, but find your passion. Everyone in technology is Continue reading
The advantages of SaaS applications and other cloud services has businesses rethinking their traditional router-centric WAN strategy. That’s because many of today’s business-critical applications carry the twin challenges of needing high performance, especially for latency-sensitive applications such as unified communications, combined with high volumes of data. These requirements can quickly swamp traditional WAN connections that backhaul data and transactions through the data center. Without the ability to connect directly to the internet, application speeds slow and performance suffers.The other challenge is that routers generally only view data at the packet level, with little to no intelligent recognition or prioritization of business applications. As a result, mission-critical SaaS applications must not only compete for bandwidth with other business data, but also with non-essential traffic such as YouTube videos or Spotify streams. Without the ability to recognize, prioritize, and steer connections to business-critical SaaS applications, it’s all just data going in and out of the branch routers. The result is lowered application functionality, user experience, and business results.To read this article in full, please click here
