Layer 2-7 Gigabit Ethernet test equipment
Xena Networks deliver breakthrough price-performance on Layer 2-7 Gigabit Ethernet traffic generation and analysis test equipment to customers around the world.
The users and customers of our Layer 2-7 Gigabit Ethernet test equipment operate in many different segments – from equipment manufacturers and telcos to large enterprise, research facilities and government organizations. So its no surprise they have very diverse testing needs.
Check the table below and see if you can find the type of testing you do.
Traffic is prioritized according to its importance and some types of traffic are more sensitive to latency, jitter and packet loss than other. Xena offers QoS validation solutions in accordance with RFC 2544 and Y.1564, as well as advanced statistics functions that help users track, analyze and troubleshoot QoS to maintain a high service quality guarantee.
Benchmark testing highlights the performance of a DUT identifying parameters like maximum throughput, latency and jitter. Testing can be done with different frame sizes to check how this affects performance, and the DUT can be loaded beyond its throughput capacity to see how this affects frame loss, latency and jitter.
Functional Ethernet testing can cover many parameters and depends on the DUT and the application. The testing will verify the basic functionality of the DUT. Functional testing can be performed during development, quality assurance and production.
Many network topologies provide resiliency to protect network services. This typically means re-routing traffic away from a faulty line section. However frame loss will occur if a connection is re-routed. When traffic with a given transmitted frame rate is sent through the connection during re-routing, packet loss can be measured and the convergence time can be calculated.

Testing that link performance complies with a Service Level Agreement (SLA) includes verifying Frame Transfer Delay (FTD), Frame Delay Variation (FDV) and Frame Loss Ratio (FLR) at the Committed Information Rate (CIR) defined in the SLA. Verifying the SLA with the Xena1544 allows doing the test on a line simultaneously loaded with traffic from other services.

Security/negative testing is typically conducted during development to highlight how a DUT handles abnormal conditions like very high traffic load, different frame sizes (incl. undersized and oversized frames), framed with different IFG settings, various types of errors and deviation of the signal frequency, as well as various DDoS attacks.
For Software Defined Networking (SDN) products it is important that they meet the Open Networking Foundation (ONF) OpenFlow specifications. It is also important to know the OpenFlow performance of the SDN products like switches performance testing will include processing time for messages sent to the switch to add, modify or delete OpenFlow rules from the switch’s forwarding table (“Flow-Mod” messages).

Conformance testing determines whether a DUT complies with the requirements stated in a given specification/standard. As an example G.8031 and G.8032 Ethernet Protection Switching typically require that switching from a faulty line to a backup line is completed in less than 50 msec. This can be verified as a part of a conformance test.
