Startup Veriflow aims to eliminate the human configuration errors that lead to outages and breaches by verifying changes against a near-real-time network state model.
The core cPacket value proposition is that of deep packet inspection and analysis at line rate in a scalable, distributed manner. Rather than merely directing traffic to various tools for analysis by creating a visibility fabric, cPacket handles both the functions of visibility fabrics as well as traffic analysis tools.
Badu Networks WarpGateway is a TCP proxy appliance improving Internet performance for wireless clients.
Brocade will acquire Ruckus Wireless, which sells WLAN hardware and software for enterprises and carriers, to tap into the growth of wireless networking.
A recent report from Infoblox says the U.S. far and away hosted the largest number of domains that were used “for hosting and launching attacks using malicious DNS infrastructure” in the fourth quarter of 2015.
TELoIP provides all the pieces of SD-WAN and packages it up for managed service providers and resellers to offer to their own customers.

Startup Cato Networks combines cloud security services and SD-WAN techniques to build a single, logical network optimized for traffic protection.
Microsoft’s announcement that it will offer SQL Server for Linux is a pragmatic way of saying “If you can’t beat ‘em, join ‘em.” It’s a grown-up business strategy for adults.
Netronome Agilio is a niche play for customers with specific compute requirements centered around OVS and, soon, Juniper Contrail. The majority of data center owners are likely to find that they just don’t have the problems that Netronome is solving, but those that do will be pleased that Netronome exists.
It’s a busy day for Cisco as it launches HyperFlex, a hyperconverged infrastructure (HCI) appliance family; and announces the acquisition of CliQr Technologies, a startup that aims to make it easier to run applications across multiple cloud environments.
There is an African proverb that it takes a whole village to raise a child. The basic meaning is that child upbringing is a communal effort. The responsibility for raising a child is shared with the extended family. Everyone participates especially the older children, aunts and uncles, grandparents, and cousins – even neighbors and friends. […]
Test results show that a Tomahawk-based switch unfairly allocates bandwidth, while a Mellanox Spectrum-based switch allocates bandwidth fairly regardless of which ports are used.
What follows is an article about how I recently rebuilt a single-purpose home NAS into a multi-purpose data services machine, all while keeping the data storage structures untouched and completely intact. Plan for about 10 minutes to read this article. Data storage is boring A couple years ago I built a NAS for personal use. […]
Packet Pushers podcasts are now available on Google Play Music. You’ll need to sign in with a Google account to listen.
Join the Packet Pushers for The Big SD-WAN Mixer and enjoy lively conversations about SD-WAN deployment and operations with network pros who make it work for their users.
Jenkins is an open software tool, typically used for continuous integration in software development. Network or system changes can be treated in a similar way as code changes are: developed, tested and deployed. Test frameworks are coming to Network world (look at TODD) but are not popular yet. Even without unit tests we can still use developer tools like Jenkins […]
Providing a comprehensive solution for global connectivity is still not a trivial task. As most global enterprises know, the scale both geographically and organizationally can kill almost any well engineered network design. Size and complexity aside, just designing for the next “XaaS” solution and cloud sprawl can greatly challenge most network engineers One approach to […]
In this pair of articles I will be dissecting the fundamentals of cooling and refrigeration from an IT engineering perspective, then going over the process of sizing a cooling system. As infrastructure engineers, we likely deal with the topic of cooling on occasion, and those occasions tend to be during a facility buildout/upgrade or outage […]
Network engineers and operators may often feel themselves at odds with network architects, who live in ivory towers and make pronouncements from on high about how a network should be set up, but aren’t actually responsible for making it work. Now for those that have listened to the Datanauts show on VCDX certification (at around […]
Share a drink with the Packet Pushers at Skyfall Lounge in Las Vegas and talk with network architects who’ve deployed SD-WAN in the real world.
Last week brought us, in my opinion some of the biggest news that I’ve read recently. In a nutshell the news was that Google is working with Rackspace and IBM and that they have created an OpenPower Foundation. In essence, they’re collaborating on open hardware designs based on the Power9 architecture from IBM and, at the […]
Recently, I had the opportunity to evaluate a Savvius Insight appliance. Like most freelance network professionals, much of my interaction with my clients’ networks is remote. This leaves me with fewer options for network analysis and troubleshooting, so I jumped at the chance to look at something that might fill that gap. The Hardware The appliance […]
Certifications happen when you break them down into their component parts and take them on one at a time. This 11-point methodology helped me complete several certifications. I hope it might help you too.
