Micro loop can be found in fast-rerouted networks. Fast reroute, as a proactive convergence mechanism, provides sub-second data plane convergence. If there are technical glitches, upstream node sends the traffic through the repaired path to the downstream device. For the downstream node to be used as a backup/repair node, it should be loop-free. What do […]

After patiently raising $312M, Nutanix says it's time to take this data-center 'war' public.
Segment Routing Fast Reroute – Traffic Engineering with Segment Routing uses LFA mechanism to provide 50 msec fast reroute capability. Current Segment Routing implementation for the OSPF uses regular LFA (Loop Free Alternate) for fast reroute in Cisco devices. Because LFA (Loop Free Alternate) has topology limitations, it does not include many faulty scenarios. On the […]

While SDN automates network configuration, it's not a replacement for network or application performance monitoring tools. In fact, monitoring tools are likely to become more capable as software-driven data streams flow in from all parts of the data center.

We’ve all been in that meeting. We’re learning the important facts about a company and their awesome technology. We think we’ve got a handle of the problem they’re solving and how we can apply it to our needs. And then…BAM! Our eyes are assaulted by a billboard full of company logos. We’re told how every one of these companies think that this product or solution is awesome. And because they think it’s awesome and bought it, you should think it’s awesome as well and buy it too.
This particular exchange in a presentation has a term: the NASCAR slide. When I came up with the term years ago during a Tech Field Day presentation, I referred to the fact that the slide was covered by all of the logos of customers and sponsors, not unlike the side of a NASCAR race car or the coveralls worn by the drivers. It turned the presentation into a giant neon sign signaling all the companies that bought the solution.
Vendors love to tell you who their customers are. They love holding those solution bidding wins over their competitor’s heads and informing the populace that a company like Victoria’s Continue reading
