A look at Cisco Tetration

Jasper Bongert takes a look at Cisco’s Tetration, which he got details about at Tech Field Day Extra at Cisco Live Europe. Jasper finds it similar in intent to looking at Netflow data, getting network telemetry without keeping full packet captures. But he highlights how Tetration is designed to do this for modern network architectures.

A look at Paessler PRTG

After seeing their presentation from Tech Field Day Extra at Cisco Live Europe, Jasper Bongertz decided to give Paessler PRTG a an extended look and write up his thoughts. It’s an impressively comprehensive rundown of the solutions monitoring capabilities. He walks through the setup processes, which is notably faster and easier than other open-source alternatives. He really likes how easy it is to setup monitoring sensors, which don’t require any complex configuration. In the end, although PRTG isn’t free like other alternative, the time you save may still make it the better value in the long run.

Programmable ASICs in Cisco Switches

Jasper Bongertz attended his first Tech Field Day presentation while he was at Cisco Live Europe. At the presentation, he learned about what Cisco is doing with programmable ASICs, including their “Unified Access Data Plane”, which allows for encapsulation or decapsulation of packets dynamically without losing performance. Jasper also liked seeing support for Netflow directly in hardware. He thinks while it’s an important network management tool, its also vital for security considerations. Overall, he thinks Cisco has an interesting approach to making ASICs a little more flexible.
