What's New?
Release 2.5.1
ASN 2.5.1 introduces a series of improvement focused on DC and Telco mode.
DC mode
TX-Only Ports: Introduced support for TX-only ports. A TX-only port is a DPDK port initialised with TX queues and started normally, without assigning RX queues, lcores, or processing pipelines. This allows the port to be used exclusively for packet transmission.
Port Traffic Aggregation (PTA): Introduced Port Traffic Aggregation (PTA), which combines 2–4 physical ports into a single logical aggregated port.
Telco mode
Improved metadata extraction and enhanced Multi-PGW support to ensure the following downlink interval KPIs are correctly updated when Multi-PGW is enabled:
KPI_UPLANE_INT_PKTS_DLKPI_UPLANE_INT_BYTES_DL
Release 2.5
ASN 2.5 introduces a series of enhancements focused on core network protocols, data extraction, security, and export flexibility, including ONES UI support. Below are the key features introduced in this release:
Core Network Protocol Support:
Diameter Gx Interface: Support for the Diameter protocol on the Gx interface (between PCRF and PCEF/P-GW). This feature supports the TCP protocol on ports 3869 and 13869. It specifically handles three message types: Initial, Update, and Termination requests.
PFCP-Sxb Support: Support for the Packet Forwarding Control Protocol (PFCP) on the Sxb interface (between P-GW-C and P-GW-U). It supports session establishment, modification, and deletion message types
Multi-PGW Support: Enhanced identification for sessions coming from different P-Gateways by extending the session key. The addition of outer IP addresses, GTP ID, and DSCP helps prevent correlation errors when multiple subscribers share the same internal IPs.
Data Extraction and Metrics:
L2 Extraction: Ability to extract Layer 2 information, including source MAC address, destination MAC address, and VLAN ID. This is supported for various packet types such as GTP-U, VXLAN, and IPv4/IPv6
KPI Interval Packets and Interval Active Packets Support: Introduction of new metrics to track the total packet count within a full interval window and "active interval packets" counted only when traffic was actually flowing
Control Session KPI Time: Addition of three new fields to control session records—previous calculation time, current calculation time, and actual interval duration—to provide high-precision visibility into the calculation window
Control Export Optimization (KPI Aggregations): Improved KPI calculation for control sessions ensuring that data contributions from user sessions terminated before an export interval are no longer lost, resulting in more accurate aggregate statistics
Security and Export Enhancements:
Hash Conversion: Support for hashing sensitive subscriber attributes (IMSI, IMEI, MSISDN) and network IPs (P-GW/S-GW IPs) using algorithms like AES-CMAC before exporting to Kafka or IPFIX to maintain data privacy
Multi-Kafka Support: The ability to export data to up to six independent Kafka brokers simultaneously for redundancy, with internal Kafka load balancing handling the traffic distribution
IPFIX Export: Support for the RFC 7011 compliant IPFIX legacy export protocol, allowing data to be sent to up to six independent collectors.
