GL Enhances Next-Generation Ethernet/IP Tester
GL Communications Inc., announced today its enhanced ExpertSAM™ (Y.1564 Testing) - a set of test procedures that test the ability of Ethernet-based services to carry a variety of traffic (voice, data, and video) at defined performance levels.
- (1888PressRelease) January 25, 2016 - Gaithersburg, Maryland, USA - The application is now enhanced to support testing 10 Gbps Ethernet links.
Speaking to the press, Mr. Jagdish Vadalia, a Senior Manager for product development of the company said, "Our ExpertSAM™ is specifically aimed at addressing limitations of legacy RFC 2544 test procedures, especially for Service Level Agreements (SLAs). It is based on ITU Y.1564 standard and and optional application available with our Next Generation Ethernet/IP Tester referred to as PacketExpert™ 10G, as well as the earlier PacketExpert™ 1G units. Now, PacketExpert™ 10G has been enhanced to support ExpertSAM™(Y.1564 Testing) functionalities for 10 Gbps as well as 1 Gbps networks. These tests are supported on each port independently."
He added, "ExpertSAM™ is a single test conducted to validate SLAs as per ITU-T Y.1564 standard. The ITU-T Y.1564 is built around two key subtests: the Service Configuration Test (SCT) and the Service Performance Test (SPT). SCT includes sequential testing of each service validating the SLA parameters. A ramp test for each service is performed to verify the CIR, and EIR. Each service is validated within the specified time duration in seconds, which is uniform across all the services."
Mr. Vadalia further added, " In ITU-T Y.1564 ExpertSAM™ test methodology, Throughput, Frame Loss, Frame Delay and Frame Delay Variation (cumulatively known as Service Acceptance Criteria, or SAC Parameters) are measured and compared to the expected values for each service ensuring it is within its committed range or the threshold defined for guaranteed traffic such as CIR. Each Service can be configured for various attributes like the Frame Size(s), Layer Header Parameters (including VLAN Tag Information), the Bandwidth Profile (CIR, EIR and Policing Rates), Color Method and SAC Parameters."
