There is nothing wrong with the above scenario. On the contrary: it was a huge success in previous centuries. Particularly during the twentieth century, traditional education, science, and technology contributed to immense progress: one key example being that life…

From OS to Industry-leading Software Stack  Cisco Internetwork Operating System (IOS) was developed in the 1980s for the company’s first routers that had only 256 KB of memory and low CPU processing power. But what a difference a few decades make. Today Cisco IOS XE runs our entire enterprise networking portfolio ̶ ̶ 80+ different Cisco platforms for access, distribution, core, wireless, and WAN. There are, with a myriad of combinations of hardware and software and physical and virtual form factors.  Many people still call Cisco IOS XE an operating system.

I recently had a virtual chat with PacketFabric CEO, Dave Ward. If you’re not familiar with PacketFabric, you will be soon.

In this Part 2, I will now provide some scenarios to compare. Congestion scenarios on highway system Given the above highway system analogy, consider two basic cases for congestion: Highway Scenario 1: A new shopping center opens nearby a particular exit and sends out a reasonable number of…

I did not sleep well last night. My rest was disturbed by oneiric memories of old situations where I wasted multiple hours in a queue, locked in my car under the sun and without an option to reach the nearby exit. Unpleasant feelings, I have to admit. Maybe not so different from what happens to storage network administrators when application users complain of poor performance and have the habit to finger point the network team….
