Performance driven traffic management

NS1 Pulsar uses Real User Monitoring (RUM) data and intelligent traffic steering to automatically direct each request to the best-performing CDN in real time. Improve end user experience, reduce cost and ensure reliability across every digital experience. 

Optimize user experience

Deliver the fastest, most reliable experience to every user, everywhere. Pulsar uses real-time latency and availability data to route each user to the best CDN for their network.

Built-in resilience and uptime

Build robust failover policies that steers traffic away from failing CDNs. NS1 Pulsar automatically routes users to healthy alternatives keeping your applications online.

Optimize CDN costs

Balance performance with cost efficiency. Define policies that favor lower-cost CDNs when all vendors meet acceptable thresholds, maximizing ROI on infrastructure contracts.

Future-proof your infrastructure

Vendor-independent traffic management, lets you add, remove or rebalance CDN providers without architectural redesigns. Automate Filter Chain changes via API or Terraform.

Features

Uncover CDN bottlenecks with real-world data

Leverage NS1’s aggregated RUM benchmarks across 20+ public CDNs and cloud regions or collect private measurements. Automatically capture real-world performance and availability data from actual users to uncover bottlenecks and identify issues that synthetic monitoring often misses.

FAQ

Multi-CDN Steering is a traffic management approach that intelligently routes user traffic across multiple content delivery networks based on real-time performance, availability and business rules to improve reliability, speed and user experience. NS1 Connect Pulsar is IBM’s advanced multi-CDN steering solution.

Yes, NS1 Pulsar enables cost-based routing policies that can steer traffic to lower-cost CDNs when performance requirements are met or shifting load when you reach your committed usage, helping you optimize your committed CDN spend.

NS1 Connect Pulsar is vendor-agnostic and works with all CDN providers including Cloudflare, Akamai, AWS CloudFront, Fastly and others. It sits at the DNS layer, acting as a neutral measurement engine and traffic controller across your CDN stack. Pulsar also supports measuring assets hosted on your private CDN for users with hybrid CDN strategies.

NS1 Connect offers API-first, DNS (or HTTP) based integration that allows teams to deploy multi-CDN steering quickly without changes to application code or infrastructure. Most teams can configure multi-CDN Steering in minutes with turnkey community data and can make configuration changes on the fly.

Pulsar can detect failures within seconds, automatically rerouting traffic to healthy alternatives before users experience downtime. The system processes real-time data from millions of measurement points globally, enabling instant traffic steering decisions that adapt to CDN failures, network congestion or any performance degradation – ensuring your applications stay available even during major internet disruptions.

Pulsar measures time-to-last-byte (TTLB) and availability of assets hosted on each of the CDNs. Measurements collected from real users are anonymized and aggregated by CDN, geography and ASN. Different asset sizes can be measured for private data with the NS1 community data supporting both latency (1x1 pixel) and large assets for some CDNs.

Yes, Pulsar can be used to route traffic alongside standard traffic filtering to balance traffic based on latency, geography, server load, network, synthetic health checks and more. Ensuring that none of your origins are overloaded and can stay online.

No, since Pulsar is seamlessly integrated with NS1 Connect’s managed and dedicated networks with built-in DDoS resiliency, you can deploy your multi-CDN traffic configuration to both networks that are designed for scale and performance.
