The Cisco ASR1000-ESP40 Embedded Services Processor (ESP) is a high-performance data-plane processing module designed for Cisco ASR 1000 Series routers. Powered by Cisco’s advanced QuantumFlow Processor (QFP) architecture, it delivers up to 40 Gbps throughput while enabling intelligent packet forwarding, security, and traffic management services at line rate.
Built for enterprise and carrier-grade networking environments, the ASR1000-ESP40 handles all critical data-plane operations, including routing, firewall processing, VPN acceleration, NAT, QoS, and NetFlow analytics, without compromising performance. Its hardware-accelerated architecture ensures low latency, scalable throughput, and efficient service delivery for demanding WAN and edge deployments.
The module supports advanced networking technologies such as MPLS, IPv6, IPsec VPN, traffic shaping, policing, and application-aware services, making it ideal for modern enterprise and service provider infrastructures. With integrated support for stateful firewall services and encryption, it provides secure connectivity across distributed networks.
Designed for high availability, the hot-swappable ESP module supports Online Insertion and Removal (OIR), enabling maintenance and upgrades without disrupting network operations. It integrates seamlessly with Cisco ASR 1000 Series routers and operates on Cisco IOS XE, supporting automation, programmability, and centralized network management.
Ideal for enterprise WAN aggregation, service provider edge routing, telecom backbone deployments, secure VPN infrastructures, and high-performance data center connectivity, the Cisco ASR1000-ESP40 delivers scalable, reliable, and intelligent packet processing for modern network architectures.
