Introduction to atapost.pl

atapost.pl is a Perl-based network traffic analysis tool developed under Cisco’s Q2 2025 Network Automation Initiative. Designed for enterprise network administrators, this utility processes NetFlow/IPFIX data streams to generate actionable insights for traffic engineering and security monitoring. The software implements RFC 7011-7015 standards while adding Cisco-proprietary enhancements for deep packet inspection.

Key functionalities include:

  • Automated traffic pattern recognition across ASR 9000/Nexus 9000 platforms
  • Real-time DDoS attack signature detection
  • BGP flow specification (Flowspec) rule generation
  • Compliance with ISO/IEC 27037 digital evidence preservation standards

Key Features and Improvements

  1. ​​Enhanced Traffic Forensics​​

    • Zero-day attack pattern recognition using neural network models
    • Integrated NetFlow v9-to-IPFIX conversion engine

  2. ​​Performance Optimization​​

    • 40% faster processing of 10M+ flow records compared to v13.2
    • Multi-threaded architecture supporting 64-core systems

  3. ​​Security Enhancements​​

    • TLS 1.3 encrypted flow metadata handling
    • Automated CVE-2025-2281 mitigation ruleset generation

  4. ​​Protocol Support​​

    • Full dissection of QUIC v2/HTTP3 payloads
    • Enhanced MPLS VPN traffic classification (RFC 4364 compliance)
