Press Release : GL Announces 10 GigE Network Testing Solutions

Gaithersburg, Maryland, USA – February 1, 2016 - GL Communications Inc., announced today its latest 10 Gbps Network Testing Solutions. 


Speaking to the press, Mr. Jagdish Vadalia, a Senior Manager for product development of the company said. “10 Gbps Ethernet offers data speeds up to 10 billion bits per second, generally over single mode or multimode fiber optic lines.  It is also referred to as 10 GE, 10 GigE, or 10 GbE.  10 Gbps is compatible with existing Ethernet protocols and can be easily integrated into existing networks.

He added, “GL's PacketExpert™ 10G with two 10 Gbps Optical Ports and two 10/100/1000 Mbps Electrical/Optical Ports provides comprehensive testing of 10 Gbps/1 Gbps Ethernet/IP networks. With the capability to generate/receive traffic with stacked VLAN (Q-in-Q) and stacked MPLS, PacketExpert™ 10G finds use in testing a wide range of networks - from testing individual links/switches, testing local Ethernet/IP networks (LAN), end to end testing of Wide Area Networks (WAN), testing Core/MPLS networks, and much more.”

Mr. Vadalia further explained, “Varieties of testing on 10 Gbps networks can be performed with a single tool - PacketExpert™ 10G. Performance testing capability includes Wirespeed BERTRFC 2544 TestingY.1564 Testing, and Smart Loopback.

GL's PacketExpert™ 10G's Wire speed BERT capability measures Bit Error Rate on Layer1, Framed Ethernet (Layer2), MPLS (Layer2.5), IP and UDP layers.  It supports generating various PRBS patterns such as 29-1, 211-1, 215-1, 220-1, 223-1, 229-1, and 231-1 including constant patterns such as All Ones, All Zeroes, Alternate Ones-Zeroes and user-defined test patterns ranging from 1 bit to 32 bits. Selection of optional sequence number insertion allows detecting out-of-sequence packets and packet loss. Both BERT and Loopback support Stacked VLAN and Stacked MPLS.  BERT can be configured to send/receive streams with Stacked VLAN/Stacked MPLS frames.  In addition, the PacketExpert™ 10G allows sending traffic of specific frame length and rate.

PacketExpert™ 10G supports all RFC 2544 Tests for the performance benchmarking of individual network elements. These include Throughput, Latency, Frame Loss, and Back-to-Back tests. Similar to BERT, RFC 2544 can be done over Framed Ethernet (Layer2), Stacked VLAN (Q-in-Q), Stacked MPLS, IP and UDP.

GL's ExpertSAM™ is intended for multiservice testing to measure the maximum performance of the device or the network under test.  ExpertSAM™ is a set of procedures that test the ability of Ethernet-based services to carry a variety of traffic (voice, data, and video) at defined performance levels. In particular, it is aimed at addressing limitations of legacy RFC 2544 test procedures, especially for Service Level Agreements (SLA). 

PacketExpert™10G supports Smart Loopback and automatically swaps the MAC,IP and UDP address/port and loops back incoming frames at full wirespeed of 10Gbps. Loopback is useful in many testing situations, where there is a need for a remote device looping back the test traffic. 

PacketExpert™ 10G supports capture of packets at wirespeed and also storing of the captured packets in popular file formats (pcap, ngpcap) for later analysis. The two 10 Gbps ports can act as a high performance network tap, capturing packets at wirespeed from both directions, at the same time acting as a transparent link between two end nodes. 

PacketBroker™ also acts as a network tap and captures wirespeed traffic in both directions. But, in this case, instead of recording the captured packets to a file, it sends the captured traffic on the output ports for real time analysis by packet analysis tools like Wireshark™, PacketScan™ etc.

GL's IPLinkSim™ and IPNetSim™ products support WAN emulation. These products are capable of emulating a WAN link, and introducing typical WAN impairments like Bandwidth Throttling, Latency, Jitter, Packet Loss, Packet Reordering, Packet Duplication, Packet Corruption, Congestion emulation etc. Both the products act as a transparent Ethernet bridge and can be connected between two LANs easily emulating a WAN link in the lab.
