Technical Transparency
How Visprisca is built.
A transparent breakdown of Visprisca's distributed architecture — from edge OpenRTB ingestion and our low-latency feature cache to rule evaluation and streaming telemetry.
System Layers
Six stages of our high-throughput pipeline.
Each tier is decoupled to guarantee resilience, low latency, and zero single points of failure under peak auction volume.
Edge Ingestion & OpenRTB Gateway
Accepts high-concurrency inbound bid requests from connected exchanges and SSPs over persistent HTTP/2 endpoints with minimal connection overhead.
- • OpenRTB 2.5/3.0 deserializer
- • Geo/IP edge resolver
- • Request filtering & rate limiting
Real-Time Feature Store & Memory Cache
In-memory caching tier that retrieves precomputed domain metrics, advertiser targeting parameters, and budget curves in fast memory lookups.
- • High-speed key-value cache
- • Campaign state cache
- • Domain performance indexes
Rule Engine Optimization (REO) Control Layer
Evaluates all user-defined campaign rules, blacklist criteria, dayparting restrictions, and CPA ceilings before pricing models compute.
- • Deterministic rule evaluator
- • Conflict detection checker
- • Safety guardrail enforcement
Machine Learning Inference & Valuation Pipeline
Runs parallel predictive models for pCTR, pCVR, and fraud filtering, translating score probabilities into dynamic bid values.
- • CTR estimation GBDT
- • Conversion factor models
- • First-price bid shading calculator
Auction Dispatch & Creative Markup Assembler
Constructs the valid OpenRTB bid response with signed creative tracking pixels, impression beacons, and win-notification macros.
- • OpenRTB response builder
- • Creative CDN token manager
- • Win notification handler
Streaming Feedback & Telemetry Ingestion
Asynchronous event stream recording auction outcomes, clearing prices, and post-click events for model updates and advertiser reporting.
- • Distributed message queue
- • Aggregated analytics store
- • Model retraining pipeline
System Integrity
Enterprise grade reliability by design.
Ad exchanges enforce strict drop rates for slow or unresponsive bidders. Our infrastructure maintains high-availability clustering and automated failover to ensure continuous auction participation.
