I’ve been thinking about what Network Telemetry will change in network equipment. It was this slide from Cisco Live that gave me a starting point:
What it highlights is that poor quality of tools for troubleshooting. We have the CLI and Packet Capture. The CLI is expensive to operate because it requires highly trained and skilled operators for even the simplest and most basic of tasks.
Packet capture on a device consumes large amounts of user time plus requires really costly features in your network hardware AND software. All of the features are required troubleshoot bugs in the vendor software (since the customer must provide information about bugs to vendors when they find them).
I’m beginning to understand why BGP Monitoring Protocol is a key transition in operating a BGP-enabled network.
