Cisco Networkers Live CLUS or whatever we call it now SDN Predictions

Booth Ding Dongs

I was emailing with my buddy Roy at SDN Central http://www.sdncentral.com/ about it would be fun to see a poll for people to guess what Cisco will do with their big SDN announcement. I jotted down four options that are all in the realm of possibility, or at least the same realm of if SDN makes sense and will adopt. Let’s say solar-system …

Northbound API Post

The Northbound API- A Big Little Problem : What is a Northbound API (Application Programming Interface) in SDN?

Change Bad

Use case for MPLS in the Enterprise for PCI Compliance

Stop Cant Do It Sm

MPLS is today’s only form of scalable network virtualization we have for now. I personally think the promise of something called SDN will move into that space soon but until then, we need network virtualization. PCI is a joke. It is a racket by Visa and banks to spread fear without any brains behind the architecture. PCI DSS v2.0 soon …

How I Learned to Hate the DCI

Internet

How I Learned to Hate the DCI: Layer 2 data center interconnects (DCI) is still alive and well. I blame VMware with vMotion and now every other Hypervisor vendor on the planet. Live workload migration is certainly vital to most operations. The further up the stack that happens the more flexibility you have with choosing more layers beneath you to reach for in …
