Network TAPs or Packet Brokers for Software-Defined Networks?

Posted by Chris Bihary on 3/7/17 8:00 AM

Centralized, programmatic control of the network—this was the major promise software-defined networking (SDN) offered when it first emerged. We’re getting there, but if the last few years have shown us anything it’s that realizing lofty SDN goals is anything but easy.

Now might not be the time to implement an a prior data model with an SDN protocol like OpenFlow, but you can still lay the groundwork for SDN in 2017.

The only question is how.

How Feasible is SDN in 2017?

Posted by Chris Bihary on 2/21/17 8:01 AM

Whether it’s the proliferation of cloud applications or growing cybersecurity demands, data centers are being forced to change faster than ever. Pushing 1G or even 10G architectures to their limits won’t work moving forward.

That’s why SDN is slowly starting to become a commercial reality (albeit slowly). We’ve looked ahead to where SDN will be in 2020, but you could argue that that’s been SDN’s problem since 2013—we keep looking ahead and commercialization continues to be delayed.

As you’re scaling a 40G or 100G network, you need to know if SDN is available right now. Moving into 2017, is SDN really feasible for you?

Network Functions Virtualization—What Is It and Why Should You Care?

Posted by Chris Bihary on 2/7/17 8:00 AM

Remember back in 2013 when software-defined networking (SDN) was going to change the 
world? It’s still the future of the data center, but the revolution is happening slower than 
people expected four years ago.

Amidst all of the SDN hype, many companies seem to have lost track of its companion 
technology—network functions virtualization (NFV). 

Some may think NFV and SDN are the same, but they’re actually complementary. If SDN seems 
too far out of reach, you might want to start thinking about laying the foundation for the future 
with NFV.

Top 7 Security Predictions for 2017

Posted by Tim O'Neill on 2/2/17 8:00 AM

As a network TAP provider, Garland anchor's security solutions for so many organizations across all public and private sectors. I like to think that working with IT’s top security professionals has given Garland and myself unique insight into the evolving threats and technical issues that can impact IT security strategies. In this post, I’d like to share some of the key trends that InfoSec will have to address in 2017 and beyond.

How Will SDN Impact the Future of Network Security?

Posted by Chris Bihary on 1/26/17 8:00 AM

While software-defined networking (SDN) is slowly working its way toward having a real impact on how network architects can keep up with increasing demands, SDN adoption is on a collision course with another key networking challenge—security.

At the height of SDN’s hype in 2013, software-centric networks were being praised by many for their potential to revolutionize network security. The hype has died down in recent years, leaving us with a more realistic perspective of the advantages and disadvantages of SDN for network security.

If you’re thinking of starting the transition from a hardware-centric network to SDN, don’t forget to weight the pros and cons in terms of network security.

­­The SDN Story Arc—Hype Is (Slowly) Becoming Reality

Posted by Chris Bihary on 1/17/17 8:00 AM

There seems to be a general belief that software-defined networking (SDN) will eventually redefine today’s decades-old, hardware-centric architectures. However, even as we look forward to the potential of SDN, it’s hard to accept the reality if you think about SDN’s past.

Although Gartner placed SDN at “rock bottom” on its 2015 Networking Hype Cycle and has it “firmly entrenched” in the trough of disillusionment for 2016, there’s hope in the narrative.

If you look at the overall story arc for SDN, you’ll see that what was once a lot of hype is now (slowly) becoming reality.
