This ensures seamless adaptability across various network environments and stringent service-level agreements (SLAs).
Security by Design: Security is embedded across all aspects of the data path without impacting router performance. The portfolio supports comprehensive protection for the control, data, and management planes. It uses technologies such as IPSec, quantum-safe MACsec, and ANYsec to secure IP networks and provides advanced, line-rate DDoS mitigation capabilities.
Advanced Network Automation: The portfolio simplifies and automates network operations through model-driven management. It leverages YANG-based data modeling for programmability and supports interfaces such as NETCONF, gRPC (gNMI, gNOI), and a model-driven CLI (MD-CLI). This enables multivendor SDN control and integration via protocols such as OpenFlow and PCEP.
