Make the Internet choose your best path.
EROS continuously samples, analyzes, and safely optimizes your edge routing—so your traffic takes the fastest, most reliable, and cost-aware path.

How EROS Works
EROS observes your live traffic and BGP state, probes each upstream, and safely biases routing toward the path that performs best—under your policies and cost caps.
Sample
Ingest NetFlow/IPFIX/sFlow + live BGP. Active probes per upstream. Target IP sets. Time-synced telemetry.
- • Multi-provider source-based routing
- • Paris-traceroute for path discovery
- • Adaptive probe cadence
- • Sub-ms timestamping (PTP optional)
Analyze
Per-prefix quality models. Right-sized prefix (/24→/21) selection. Anomaly detection. Policy guardrails.
- • RTT / jitter / loss / stability scoring
- • Path-equivalence grouping
- • Dwell time & hysteresis filters
- • Cost & commit awareness
Optimize
Scoped BGP injections (NO_EXPORT). LOCAL_PREF and provider communities. Automated rollback. Change budgets.
- • Safe, scoped route preferences
- • Provider-specific levers
- • Automatic regression detection
- • Cost cap enforcement
Example Policy (Pseudo-DSL)
policy optimize-latency {
target: prefixes-with-tag("latency-sensitive")
metric: rtt
threshold: improvement >= 8ms for 5min
max-changes: 2/hour/prefix
scope: NO_EXPORT
cost-cap: respect-95th-percentile
rollback: on-regression or no-effect after 10min

Change Hysteresis
Only shift routes when sustained improvement is detected.
- • ≥ 8–10 ms sustained improvement
- • ≥ 1.5× jitter improvement
- • Sustained for ≥ 5 minutes
- • Max 2 changes per prefix per hour
Blast Radius Limits
Prevent cascading failures with strict change budgets.
- • Max N optimized prefixes per provider
- • Most specific: /24 (tunable)
- • Default NO_EXPORT on injected routes
- • Never influence beyond local AS
Cost Awareness
Optimize performance while respecting your budget constraints.
- • Respect 95th percentile / commit levels
- • "Optimization under cap" mode
- • Cost wall for expensive paths
- • Override only for critical traffic
Automatic Rollback
Detect and revert changes that don't improve performance.
- • Regression detection within 10 minutes
- • No-effect detection and revert
- • Full change audit log
- • Before/after traceroute snapshots
High Availability
