Two weeks ago, I mentioned how the topic of denial-of-service DDoS issues, and the potential of BGP Flowspec (BGP-FS) as a way to mitigate them, was a very hot topic at NANOG 68 in Dallas. In general, this topic is top of mind for everyone, especially with the very recent widespread cyberattack. Let’s take a look at the continued evolution of methods to handle these attacks.
Traffic filtering policies have traditionally been very static in service provider networks. But in this age of traffic-based, and more widespread, DDoS attacks, operators need to create dynamic filters

At VMworld Barcelona today, Fujitsu announced their PRIMEFLEX for VMware Cloud Foundation integrated system. Brocade® VDX switches are the connective tissue for this new hyperconverged infrastructure option. In this post we’ll take a look at the drivers and benefits of this latest collaboration between Brocade, Fujitsu and VMware.

For my twenty or so years in computer networking, the promise of a network that is sensitive to the applications running on it has been put forth almost continuously. And to some extent, constructs such as Quality of Service (QoS), policy-based routing, and even simple logical domain separation through subnetworks and VLANs have provided the support to improve application performance.
As part of the digital transformation, however, applications are becoming much more complex

The many approaches to data center design strategy can be confusing. But, essentially there are 2 approaches – a vertically integrated complete stack solution or build your own stack. There is a parallel here with bring-your-own-device and bring-your-own-app.

The Product Management team in Brocade’s Switching, Routing and Analytics Business Unit is shipping the 230Tbps-capable SLX 9850 router to NANOG 68 in Dallas (October 17-19). It will be presented at NANOG’s “Beer and Gear” event on Tuesday afternoon, October 18 at 6:00PM.
This high-end router is especially suited to IP fabric and core-aggregation
Have you ever thought about what types of cars are passing through an intersection, whether there are any accidents or if cars are ignoring traffic lights? Operators use cameras and sensors to get visbility into traffic intersections. Do you have the same visibility into your network? ...

It’s August and that means it’s time for VMworld 2016 in Las Vegas! This is THE destination to find all the sexy things you’ve been peeking at online and just never get the chance to sample in real life. And there’s also Vegas entertainment if that’s your thing instead…

The latest release of VMware NSX-V and the accompanying networking HW certifications for vendors including Brocade is an exciting new step towards driving agility across IT and delivering increased value from the network to the business. At Brocade, we are delighted to be the first HW VTEP to be listed in the VMware Compatibility Guide.
Network automation can’t be addressed with “protocols” alone! The missing piece in network automation puzzle is a software framework that addresses the inefficiencies in today’s model with the following characteristics:

We have all seen it happen; a company rolls out a new ecommerce platform, or online ‘always-available’ customer services, or deploys new security as proof that they are taking the safety of customer data seriously after the last breach. All seems wonderful until… the system fails. Customers take to social media to vent frustration, regulators circle, fines accrue.
The executive management convene to pore over what went wrong. ‘We deployed the latest applications’, they say. ‘We invested in more servers. We ensured everyone did the training. We issued the press release’. However, the one thing they didn’t ask at the critical moment before making any transformation or investment was ‘can our network handle it’?

From your home office to the Amazons of the world, there is always a way to be more environmentally conscious. Being more sustainable means using less energy, effort, time, and thus spending less money. Keep reading for ways companies of any size could go green while saving green:
Google took the ultimate steps in going green by building a data center from a converted paper mill in Hamina, Finland. The building utilizes a pre-existing tunnel system that pumps raw seawater from the Gulf of Finland into heat exchangers to cool the routers and switches. The system then re-cools the warm water so it can be returned to the gulf closer to its original temperature and minimize any adverse environmental effects. The cooling method uses no compressor or refrigerant based cooling, only natural resources.
Although it was originally conceived in 1973 at Xerox Parc, it was the 1980 specification jointly issued by Digital, Intel and Xerox on September 30th that really got the ball rolling on the Ethernet we know today. Yes, it was “only” 10Mbps. Yes, it used “vampire” taps. But for its time it was progress. It was good enough and cheap enough to get people interested in using it rather than the alternatives of the day.
But it would have faded out had it not shown the ability to evolve several aspects when necessary: transmission medium, link connectivity, and speed. Critically, that evolution happened just in time for the early majority of the target markets, and there are workarounds for early adopters, e.g. link aggregation groups, or accept the risk of using pre-standard specifications.
You’re at the sharp end of IT in your organization, so you’re probably seeing the same fundamental shifts in behavio r impacting other enterprise IT departments.
There’s a rise in traffic volumes and a change in traffic patterns. That’s partly due to the sheer volumes of data unleashed by server virtualization. More comes from the emergence of new business apps and services.
And even greater amounts of data are forecast as the Internet of Things (IoT) becomes a reality.
More immediately, user expectations for speed and agility are on the rise and will only increase.
