Gaithersburg, United States – GL Communications Inc., a provider in telecom test and measurement solutions, addressed the press regarding their enhanced quad port ethernet tester – PacketExpert 1G.
“PacketExpert is a portable Ethernet / VLAN / MPLS / IP / UDP tester. Each port provides independent testing at wire speed. It can conduct bit error rate testing, RFC 2544, Loopback, packet recording and playback, Multi-stream UDP/TCP traffic generation and ITU-T Y.1564 testing for verifying service level agreements. GL can also provide supporting SFPs and cables for a ready to use test solution.,” says Vijay Kulkarni, CEO of GL Communications.
Main features
- Wirespeed bit error rate testing (BERT)
- User configurable traffic rates and frame sizes
- RFC 2544 – Throughput, latency, frame loss, and back-to-back performance tests
- Available in portable or rackmount configurations. Rack-based variants provide up to 12 or 24 ports housing multiple PacketExpert devices
- Easily control multiple devices and ports from a single graphical user interface
- Automation, remote operation, and multi-site connectivity using C# and Python clients
- Supports both smart loopback (auto layer detection) and user-defined layer-wise loopback capabilities for incoming traffic
- Can function as a wirespeed ethernet tap to capture and filter real world traffic, generate triggers based on filters, and transmit filtered/aggregated/modified packets for deep packet inspection
- Wirespeed capture and playback testing provides packet capture, filter, aggregate, and storage features
- Supports industry standards PRBS patterns 29-1, 211-1, 215-1, 220-1, 223-1, 229-1, and 231-1, and constant patterns like all ones, all zeroes, alternate ones-zeroes and user-defined test patterns ranging between 1 to 32 bits
- Provides various vital measurements such as bit error rate, bit error count, sync loss count, sync loss seconds, and error free seconds
Recent enhancements
- BERT:
- Option to disable auto-negotiation for 1000Base-T (1000 Mbps Electrical)
- Added additional 1000Base-T Interface parameters when auto negotiation is disabled
- Enhanced to support burst mode traffic generation ability
- Packet recording and playback applications:
- Multi-device support capability
- RFC 2544:
- Added measured Latency display for both Store/Forward and Bit Forward methods
- ITU-T Y.1564 testing:
- Multi-device support capability
- Client application programming interface (API)s:
- Added new APIs for ports with 1000BaseT forced speed parameters, starting/stopping BERT on multiple ports together
