Avi Freedman, co-founder and CEO of Kentik, demonstrates how to build a monitoring dashboard for cloud-native applications during the Packet Pushers’ Virtual Design Clinic 4 held on March 14, 2019.
I often see people on forums saying, “We want to do network automation, but we don’t know where to start.” In my opinion wanting to start is the best place. Pick up something and play around with it in the lab. That’s the best way to get started. However, if you are working in a […]
Network rookies leave spanning tree at defaults. The root bridge ends up as some switch in a closet. A new switch is added to the network, and sometimes traffic goes wonky for a while. Spanning tree gets blamed as if it’s a teenager with an attitude problem. Wrong. Spanning tree just needs to be managed, […]

ThousandEyes’ 2018 Public Cloud Performance Benchmark Report compares overall and regional network performance of AWS, Azure, and Google, including average, normative, and best-in-class performance. This data can help inform your network design choices, and whether you’ll want to pay the cloud providers to use their private backbones.
This is a brief overview of two methods of segment routing: SR-MPLS and SRv6. I provide a quick comparison of the two approaches, and examine some of the challenges facing SRv6.
Cato Networks has added a new managed threat detection and response service to its SD-WAN portfolio. The service aims to reduce the dwell time of a malicious intruder to limit the damage of a security compromise.

Live and online, you can watch technical presentations and get your networking and design questions answered by experts–all from your laptop!
My experiences in networking engineering and media have changed the way I think about standards bodies, tech conferences, sales and marketing, and tech support–and not for the better.
Kemp Technologies’ 360 Vision predictive analytics platform can now collect and analyze data from F5 and NGINX load balancers.
Your customers want clarity about your product’s capabilities, not empty jargon. Your customers want to solve problems, not tick a buzzword box. Stop playing marketing games with “Intent-Based”
Fortinet has announced four new FortiGate next-gen firewalls (NGFWs), with throughputs up to 40 Gbps in NGFW mode depending on the model. As with other FortiGates, the new firewalls include custom ASICs, which Fortinet calls Security Processing Units (SPUs). The SPUs on each box divide security and networking tasks to improve overall performance. For instance, […]
The recent funding announcement from Cato Networks highlighted an important point for those of us involved in rethinking enterprise networking: how SD-WAN is only a partial answer to enterprise networking problems. Cato: funding and 2018 results The announcement included several important elements including: a $55 million funding round led by LightSpeed Ventures an increase in […]
Setting up Python on the MacOS can be a challenge. Here’s seven options the community suggested to create a less fragile development environment.

The gray market for IT gear is driven by high vendor prices for new products and by unscrupulous people looking to make a quick buck. Here are four aspects of the gray market that I’ve observed.
It was a little over a year ago, that I sat back in my theoretical chair at my cushy enterprise job and started thinking about what was next. There was a good amount of change and velocity in the role that kept me satisfied for the past six years, but there was also a growing […]
LogicMonitor, which sells a SaaS platform to monitor IT infrastructure and public cloud performance, has launched new offerings for Kubernetes and a service-oriented view of infrastructure components.
Transitioning from MPLS to SD-WAN is a big move. It’s important to remember, however, that even the most dramatic transition requires that attention be paid to small and mundane details. Not doing so can cost time and money — and not a small amount of either. I speak to a lot of companies. One of […]
The repercussions of the CenturyLink outage are still being felt weeks after the provider announced the problem solved. Even the FCC has gotten involved, announcing an investigation into what happened (see our blog on SD-WAN-Experts for more details). For enterprise IT, the outage certainly should give pause for anyone considering CenturyLink’s backbone as part of […]
If you’ve been in IT for more than a few minutes you been here before. Widget X is burning, the organization is hemorrhaging cash, and we’re all doomed unless some caped infrastructure superhero swoops in to save the day. You’re just the hero for the job, but what are you going to do? I’m going […]
