Eric Dennington @edennington, Steve Occhiogrosso @StephenO86, and Jason Lavoie @ratvarre join the Packet Pushers to chat about building a new network from scratch. We compiled our notes, and decided on a three phase approach.
Phase 1: Design
- Understand the organization you’re building the network for. You need business requirements.
- Learn about your facilities. New? Old? What’s there already?
- How will legacy be integrated?
- How will the design evolve as needs grow & technology changes in coming years?
- Document the plan. If it’s all in your head, you’re doing it wrong.
- Involve others. Don’t do it alone. Once again, if it’s all in your head, you’re doing it wrong.
Phase 2: Build
- Lab work. Prove your design. Assume nothing.
- Deploy in stages.
- Monitor what you’ve built.
Phase 3: Operate
- Test again after production implementation is final.
- Improve monitoring, especially as unforeseen situations come up.
- Keep communications open with the business and other teams about performance, issues, etc.
