dsh-bandwidth

Planning a network link, rolling out an online service, or sizing system throughput often leaves bandwidth estimation to a gut-feel rough guess. dsh-bandwidth turns that fuzzy judgment into a repeatable, parameter-driven calculation so the numbers speak for themselves.

It takes structured parameter input, computes the required bandwidth through precise formulas, and returns a detailed breakdown that includes intermediate steps rather than a single opaque final value. The entire implementation is pure Node.js with zero network calls and zero third-party API dependencies, so it runs perfectly offline with virtually no additional runtime burden.

It is well suited for network engineers, DevOps practitioners, and indie developers who need to quickly quantify link capacity before a design review, a capacity-planning cycle, or a solo project launch. When you want concrete figures instead of experience-based estimates and prefer a lightweight tool that requires no external service, this is the handy option for the job.
