ShortestPathFirst now has a new, shorter domain name (spfirst.net) that we intend to use for future correspondence, marketing and business initiatives. We will continue to maintain the longer domain (shortestpathfirst.net) for backward compatibility and for business continuity but for all intents and purposes will use the new domain name where possible. Stay tuned for lots …
With new technologies such as automation and artificial intelligence (AI) emerging all around us, enterprise digitalization is inevitable. But however much enterprises want to transform, there is a significant cost in terms of time and technological manpower to ensure the system runs smoothly. In particular, enterprises are often faced with a variety of human factors that can hamper digitalization projects, including organizational resistance to change, lack of a clear vision, and inability to gather and leverage customer data, to name just a few.On the technical front, the challenge is in finding the right products and services to overcome the inflexibility of technology stack and development processes. Therefore, picking the most suitable and flexible solutions to meet the transformation challenges is usually the key to success. The right solution not only streamlines deployment but also makes it easier for people who are involved in the exercise – the easier the jobs, the less reluctant the organization towards the changes.To read this article in full, please click here
Previously, I’ve written a number of articles that compared syntax between Cisco and MikroTik and have received some great feedback on them.
As such, I decided to begin a series on Juniper to MikroTik starting with MPLS and L3VPN interop as it related to a project I was working on last year.
In the world of network engineering, learning a new syntax for a NOS can be overwhelming if you need a specific set of config in a short timeframe. The command structure for RouterOS can be a bit challenging if you are used to Juniper CLI commands.
If you’ve worked with Juniper gear and are comfortable with how to deploy that vendor, it is helpful to draw comparisons between the commands, especially if you are trying to build a network with a MikroTik and Juniper router.
Lab Overview
The lab consists of (3) Juniper P routers and (2) MikroTik PE routers. Although we did not get into L3VPN in this particular lab, the layout is the same.
A note on route-targets
It seems that the format of the route-target has some bearing on this being successful. Normally i’ll use a format like Continue reading
A little while ago I explained why you can’t use more than 4K VXLAN segments on a ToR switch (at least with most ASICs out there). Does that mean that you’re limited to a total of 4K virtual ethernet segments?
Of course not.
You could implement overlay virtual networks in software (on hypervisors or container hosts), although even there the enterprise products rarely give you more than a few thousand logical switches (to use NSX terminology)… but that’s a product, not technology limitation. Large public cloud providers use the same (or similar) technology to run gazillions of tenant segments.

Following on from the STELLA report, today we’re going back to the
first major work to study the human and organisational side of incident
management in business-critical Internet services: John Allspaw’s 2015 Masters
thesis. The document runs to 87 pages, so I’m going to cover the material across
two posts. Today we’ll be looking at the background and literature review
sections, which place the activity in a rich context and provide many jumping
off points for going deeper in areas of interest to you. In the next post we’ll
look at the detailed analysis of how a team at Etsy handled a particular
incident on December 4th 2014, to see what we can learn from it.
Why is this even a thing?
Perhaps it seems obvious that incident management is hard. But it’s worth
recaping some of the reasons why this is the case, and what makes it an area
worthy of study.
The operating environment of Internet services contains many of the
ingredients necessary for ambiguity and high consequences for mistakes in the
diagnosis and response of an adverse Continue reading
A decade or so before the GPU started storming the datacenter thanks to Nvidia’s Tesla GPU accelerators and their CUDA parallel programming environment and CPU offload model, FPGAs were starting to gain traction as accelerators in their own right. …
Setting up an account on a Linux system that allows you to log in or run commands remotely without a password isn’t all that hard, but there are some tedious details that you need to get right if you want it to work. In this post, we’re going to run through the process and then show a script that can help manage the details.Once set up, passwordless access is especially useful if you want to run ssh commands within a script, especially one that you might want to schedule to run automatically.It’s important to note that you do not have to be using the same user account on both systems. In fact, you can use your public key for a number of accounts on a system or for different accounts on multiple systems.To read this article in full, please click here
Proactively fixing a network problem before it becomes a full-blown nightmare is the goal of new software Cisco has added to its Data Center Network Assurance and Insights suite.Cisco Assurance is a key component of the company’s intent-based networking initiative that maintains a continuous validation and verification that the network is doing what the customer expects. [Get regularly scheduled insights by signing up for Network World newsletters.]
Network Insights is software Cisco customers use to monitor and record hardware and software telemetry data over time to identify anomalies in the fabric and help automate troubleshooting, root-cause analysis, capacity planning and remediation, according to Cisco. For example, Network Insights can watch over network component usage patterns and audit logs, events, and faults as well as latency conditions from Cisco Application Centric Infrastructure or Data Center Network Manager (DCNM) network fabrics.To read this article in full, please click here

For years, enterprise networking and security leaders have had to weather the complaints and consternation of IT and business executives. IT costs too high? Blame that MPLS network. Web taking too long to load? It’s that darn VPN client again. Now a new product category, Secure Access Service Edge (SASE), is supposed to put networking and security teams firmly ahead of the game. So impactful is this new sector that Gartner’s termed it “transformational,” a lofty status that not even SD-WAN, with all of its market impact, ever achieved. Within four years, Gartner expects 40% of enterprises will have strategies to adopt SASE.To read this article in full, please click here
