Resources
Plain-English explainers for the concepts behind m-cdn — the standards we read, how the engine decides, and the controls you tune. Linked from the inline ? help across the console.
Tools
How m-cdn routes
Multi-CDN switching
Steering viewers across several CDNs — including mid-stream — so a degrading network never decides your quality.
Decision Engine
The scorer that re-ranks your CDNs on every tick and decides who serves each region and network.
Content Steering (vs DNS)
The HLS/DASH standard that lets a player ask which CDN to use next, mid-stream — and how it complements DNS steering.
Geo & network routing
Why m-cdn decides per region and per carrier (ASN) instead of one global winner.
Standards & signals
CMCD
Common Media Client Data — the standard that lets the player tell m-cdn how playback is actually going.
CMSD
Common Media Server Data — the CDN's side of the conversation, returned in response headers.
SCTE-35
The ad-insertion and content-boundary signalling standard m-cdn must preserve byte-for-byte across a switch.
Signal tiers
How m-cdn ranks its inputs by trust — CMCD > CDN logs > probes > DNS — and surfaces the confidence on every decision.
Controls you tune
Budget & cost modes
Capping spend in dollars or traffic, and how a hard cap changes routing rather than just alerting.
Quality-floor mode
Invert the optimisation: set a minimum acceptable quality, then spend the least that keeps you above it.
ABR variant filtering
Shaping which bitrate rungs the manifest exposes per request — by cost, entitlement, time, geo, or network.
Viewer entitlements
Deciding what each viewer is allowed to receive — enforced by signed tier attestation, not by trust.
Deployment & data
BYOC — bring your own cloud
Running the data plane in your own cloud account, under your own keys, so raw telemetry never leaves your boundary.
Deployment models
Self-managed in your own cloud vs m-cdn Cloud — the same engine, two operational boundaries.
DNS delegation
How m-cdn updates DNS to steer viewers — by delegating a sub-domain or by scoped write access to your own zone.
