Ethernet traffic continues to surge, driven by high-bandwidth workloads such as Artificial Intelligence. To keep pace, network engineers require diagnostic solutions that can interface with 400 Gbps ultra-high-speed links, capture traffic without loss, and provide real-time analysis within a single integrated platform.
Vijay Kulkarni, CEO of GL Communications, states “GL’s FastRecorder™ is an all-in-one hardware platform for lossless high-speed Ethernet traffic capture across multiple ports. The system is available in both rack-mount and portable form factors. Both platforms are designed for continuous packet capture and real-time analysis in labs, data centers, and field environments.”
The rack-mount version features dual processors and supports multiple 400 Gbps ports, achieving an aggregate capture rate of over 800 Gbps with up to 600 TB of NVMe storage. The portable version includes a single processor and multiple 400 Gbps ports, delivering an aggregate capture rate of more than 400 Gbps.
FastRecorder™ provides a secure Linux-based web interface for remote, multi-user access, along with automation support via Python and REST APIs. Users gain full visibility into performance through detailed capture metrics, including duration, data rates, frame statistics, dropped packets, total recorded bytes, link status, bandwidth usage, error counters, and frame length distribution.

Captured traffic can be processed using extractor module (PacketExtractor™) to isolate specific streams, headers, or time windows. Output is available in PCAP/PCAPNG formats with extraction metrics such as frame count, data volume, extraction rate, and processing time. The extracted files can then be seamlessly analyzed with GL’s PacketScan™ software.
Other Key Features
- Nanosecond timestamping
- Duplex 400 Gbps capture (400 Gbps East + 400 Gbps West) for up to 800 Gbps total to SSDs, recording up to 6 TB per minute
- Apply hardware filters (MAC, 802.1Q VLAN, IPv4, IPv6, Tunnel traffic (GRE, GTP, and VXLAN), TCP, UDP, SCTP) to capture traffic of interest
- Real-time port insights including status, received frames, link utilization, capture rates, error counts, and frame length distribution
- Real-time graphs for each port to analyze capture rates and detect issues such as segment drops, Multi-Packet Receive Queue (MPRQ) buffer overflows, missed packets, and discarded packets
