The VIAVI ONT family of Ethernet testing tool incorporates РІР‚СљstressedРІР‚Сњ latency testing and margin analysis to measure performance under more realistic conditions. Latency measurements performed in a lab environment can sometimes lack the network errors and other timing stressors that systems or components will experience in the real world. Even minor changes in packet latency can disrupt the tuning and optimization of optical modules, integrated circuits (ICs), and other Ethernet network components. Nanosecond resolution, high precision, and accuracy are required for test solutions characterizing components and modules for 400G. As Ethernet speeds increase, there is a growing need for latency measurement and baselining of system components. Errors, physical distance, buffering issues, and switches all contribute to cumulative latency. High performance Ethernet requires low and stable latency. Latency is any delay in the network that slows down Ethernet packet transfer from source to destination. The lab to field Ethernet testing philosophy adopted by VIAVI has yielded multi-technology, automated protocol testing in handheld devices along with scalable, high-density Ethernet test equipment and modules to accelerate development.

Sophisticated, high-density, rack-mounted Ethernet test equipment provides a common platform for design, system verification and manufacturing testing.Р”В¬ompact, easy to use, and portable Ethernet network test devices and Ethernet cable test devices round out the portfolio by supporting the balance of the network lifecycle. This is reflected in versatile Ethernet test solutions for development teams, manufacturers, and live network applications. VIAVI Ethernet Test Equipment incorporates the knowledge and insight garnered through decades of standards development participation and field experience gained alongside customers and manufacturers. A TWAMP test setup can use many types of test points at the far end including a portable device, a small form pluggable, or even a software-based test agent. The Two-Way Active Measurement Protocol (TWAMP) is another standards-based test method ( RFC 5357) used to actively monitor Ethernet circuit performance. Co-authored by VIAVI, the RFC 6349 protocol measures outputs that directly impact the userРІР‚в„ўs web browsing experience. Transmission efficiency is determined based on factors including retransmission percentage and buffer delay. It provides a reliable and repeatable method for testing end-to-end transfer performance. RFC 6349 is a new methodology to measure Layer 4 transmission control protocol (TCP) traffic. These same standard tests can be used to troubleshoot post-activation issues.

Y.1564 and RFC 2544 test protocols have been developed to validate network service level agreements (SLAs) and quantify key performance indicators including throughput, latency, frame loss, and back-to-back frames (buffer operation) during Ethernet circuit characterization and service activation. Although it is useful to understand what is happening at the higher network layers, Ethernet testing targets the verification of lower layer performance. This technology has continued to evolve as top Ethernet speeds have gradually increased from 2.94 Mbps to 800 Gbps (800G).Р”В®thernet test practices focus on layers 2 and 3 of the network stack, as defined by the Open System Interconnect (OSI) model.

The IEEE 802.3 standard defines the packet-based transfer mode of Ethernet. Ethernet is a family of computer networking technologies used to connect local area networks (LAN), wide area networks (WAN), and metropolitan area networks (MAN) over twisted-pair or fiber optic cabling.
