Cisco Silicon One P-Series
The P-Series and Q-Series deliver power-efficient, deep-buffer routing silicon for data center interconnect, WAN, and core routing. From the 51.2 Tbps P200 to the foundational Q100 that launched the Silicon One brand, these processors provide industry-leading AI network scale.
Product Overview
Deep Buffer Routing
Purpose-built deep buffers handle bursty traffic patterns across WAN and DCI links, ensuring reliable packet delivery.
Up to 51.2 Tbps
The P200 processor delivers 51.2 Tbps for next-generation core routing and data center interconnect.
Power Efficient
Industry-leading performance per watt reduces operational costs and environmental impact across large-scale deployments.
Scalable Architecture
Massive routing table scale with flexible forwarding pipelines support millions of routes for service provider and enterprise cores.
Security Built In
Hardware root of trust, MACsec, ACLs, and DDoS mitigation protect critical infrastructure at line rate.
One SDK
Unified development across P and Q series with SAI, SONiC, and IDE-based programmability.
