GL Announces PacketExpert™ – A Wirespeed Ethernet/Packet Tester

GL Communications Inc., announced today the release of its newest product PacketExpert™ – A Quad port wirespeed Ethernet/Packet Tester. Addressing the press conference, Mr. Jagadish Vadalia, Senior Manager said, “PacketExpert™ is a quad port wirespeed Ethernet/Packet Tester. It supports 4 Gigabit Ethernet ports and connects to the PC through a USB 2.0 interface. Each GigE port provides independent Ethernet/IP testing at wirespeed for applications such as BERT, RFC 2544, and many more. It truly takes confusion out of Ethernet testing at all protocol layers – from raw Ethernet to IP/UDP packets. It can also be used as a general purpose Ethernet performance analysis tool for 10/100 Mbps or 1 Gbps Ethernet local area networks. Two of the 4 ports have both Electrical and Optical interfaces, enabling testing on optical fiber links as well”.

He added, “A BERT application measures Bit Error Rate on Raw unframed Ethernet (Layer1), framed Ethernet (Layer2), IP and UDP data streams. Various PRBS patterns such as 29-1, 211-1, 215-1, 220-1, 223-1, 229-1, 231-1 are supported. Also All Ones, All Zeroes, Alternate Ones and Zeroes patterns are provided as well as user-defined test patterns ranging from 1 bit to 32 bits. PacketExpert™ supports user-defined options to configure Ethernet/IP/UDP header parameters, including VLAN, Frame Size, and Rate”.

Mr. Vadalia further added, “Per RFC 2544 specifications, PacketExpert™ supports Throughput, Latency, Frame Loss Rate, and Back-to-Back tests. It includes various parameter configurations such as Test Selection, Frame Sizes, Unidirectional/Bidirectional, Number of trials, Trial Duration, and many more. User-defined options to configure various packet header parameters, like MAC addresses, IP addresses, UDP ports etc. Results are displayed in both tabular as well as graphical format”.

Important features

• Quad port Gigabit Ethernet tester, generate/receive Ethernet traffic at wirespeed.
• Wirespeed BERT over Raw unframed Ethernet (Layer1), Framed Ethernet (Layer2), IP and UDP on only one port.

RFC 2544

• Throughput, back-to-back, latency and frame loss measurements as per RFC 2544 (Uni-directional and Bi-Directional simultaneous testing between ports also supported)
• Provides flexibility to configure various test parameters like test selection, frame size selection, individual test parameters like trial duration, number of trials, etc.
• Provides results in both tabular format as well as graph format.
• ERT – supported PRBS patterns are 29-1, 211-1, 215-1, 220-1, 223-1, 229-1, 231-1and User Defined test patterns ranging between 1 to 32 bits
• Bit Error Insertion for both single as well as Rate Error
• Portability through a USB 2.0 Interface
• 2 ports have Electrical and optical interfaces. User option provided to switch from electrical to optical and vice versa.
• Electrical ports can operate in 10/100/1000 Mbps speed and Optical Ports can operate in 1000 Mbps speed
• Detailed frame statistics per port.
• Loopback capability for incoming traffic. Both smart loopback (auto loopback) and user-defined loopback capability supported.
• Capability to generate/respond to ARP requests, making it easy to work with Routers
• Frame lengths from 64 bytes to 1518 bytes, Jumbo frames also supported
• Capability to modify various header parameters for MAC, IP and UDP layers. VLAN also supported.
• Option to insert sequence number to measure Out Of Sequence Packets and packet loss
