Release 4.6: Multi-Hop Path Measurement, DTLS Analysis, and Enhanced CSV Export

Leipzig, March 11, 2026 – The new firmware expands the analysis capabilities of the Allegro Network Multimeter and improves transparency in network traffic.

Users benefit from extended measurement options, more detailed log evaluations, and more flexible exports. In addition, the update supports the analysis of length-restricted packets that are forwarded by packet brokers at a reduced length.

Highlights of the new firmware release:

Multi-hop path measurement: Path measurement now supports up to eight measurement points. The system records and evaluates latency and packet loss for every individual hop between configured points, providing separate IP pair statistics for each combination. The view can be narrowed down to a specific start and end device so that latencies on selected measurement hops can be quickly identified. In addition, multi-hop path measurement can also be applied to multiple PCAP files.

DTLS analysis for encrypted TLS traffic over UDP: DTLS data is now seamlessly integrated into the existing TLS statistics. This includes comprehensive visibility into DTLS versions, cipher suites, and certificates. Furthermore, the connection details now feature an analysis of DTLS sequence numbers, allowing users to pinpoint packet loss, out-of-order transmissions, and record/handshake retransmissions.

More tables can be downloaded as CSV files: Additional tables can now be exported as CSV files. These include IP group statistics (protocols, IP list, RTP), IP statistics by protocol, and MAC statistics for individual MAC addresses. In addition, QoS statistics by class, SIP statistics with details on request methods and SIP connections, RTP statistics, and IP geolocation statistics, including the country IP table, can be downloaded in CSV format.

Extended support for analyzing length-restricted packets: The “External Original Packet Lengths” function now supports two types: the Ixia trailer and an IP header-based type. In IP header mode, the total length set in the header is used to calculate traffic instead of the actual packet length. This makes evaluation possible when packets are truncated and no trailer with the original packet length is available, for example when using different packet brokers.

Extended long-term database with historical analysis for peers & IP pairs: The long-term database has been significantly expanded. The peers table and the global IP pair list are now also available in long-term mode. This means that communication relationships and connection details can now be tracked and evaluated not only in real time, but also over longer periods of time.

These features, alongside various performance optimizations and bug fixes, are now available to all Allegro Packets customers.
