Application Emulation
Testing with realistic network traffic places the device under test (DUT) in a realistic network environment and delivers authentic results.
All of Xena’s products can be used for performance testing. This typically includes measuring:
- the volume of data successfully delivered between two points, usually measured in bits or packets per second
- how long it takes data packets to travel between two points in a network or a device, also known as latency
- variations in latency – also known as jitter – due to network congestion or other factors
- how many data packets fail to reach their destination
- if data packets are delivered in a different order from that in which they were sent
Testing can be done with different frame sizes to check how this affects performance. Similarly, the DUT can be loaded beyond its throughput capacity to see how this affects frame loss, latency and jitter.
Valkyrie includes free applications for testing in accordance with IETF RFC 2544, RFC 2889 and RFC 3918. Valkyrie also supports VSperf testing.
SERVICE PROVIDER
In the highly competitive Service Provider market, success is built on reliably giving users a first-class experience on the latest services for the lowest possible cost.
GPON TESTING
The R&D department of a major NEM in China was developing new GPON ONU access solutions for transportation. To validate the performance of the new products, they needed to generate stateless Ethernet traffic at 100GE, as well as 25GE and 50GE. Two key requirements were that the test equipment should be portable and provide two 100GE ports.

Automotive Ethernet
The automotive industry is finally going digital. Initiatives like the BroadR-Reach 100 Mbit/s Automotive Ethernet standard seek to minimize the weight and cost of electrical cabling – now the 3rd largest weight component.
Latency & Jitter
This White Paper clarifies terms used in time measurement e.g. latency, jitter, inter-frame gap, latency resolution, speed mismatch, latency over time, and distribution and presents how Xena interprets and implements time measurements.
The Case for 25GE & 50GE
Data centers are hungry for bandwidth but strapped for cash. Adding more 10GE equipment is a short-term solution but upgrading to 40/100GE is expensive.
GPON Testing
Gigabit-capable Passive Optical Networks (GPON) support digital communication to end customers at rates up to 2.4 Gbps downstream and 1.2 Gbps (optionally 2.4 Gbps) upstream. A GPON requires active transmission equipment at its borders, and this equipment will of course need to be tested.
Xena NetworksTesting VNF
This White Paper demonstrates how the goals listed above can be achieved using Xena’s stateless traffic generator on configurations orchestrated by CNLabs NFV Test Framework. The open source firewall pfSense is used as the Virtual Network Function.
TCP Testing
TCP turns the ‘best effort’ nature of IP networks into reliable communication services. This White Paper explains how RFC 6349 based TCP throughput tests and stress load tests give network operators valuable information on network TCP performance.
GPON Certification with LAN
This White Paper examines the background for BBF.247 testing and how LAN - the Laboratoire des Applications Numériques - uses Xena’s solutions for their formal certification process.
Evaluate Data Center Network Performance
Data center network topology is crucial to latency in the network. Therefore, it is important to know the impact of new topologies before they are deployed.

To rigorously test the performance of next generation firewalls (NGFWs), it is no longer enough to bombard them with dummy traffic.
Putting 2.5GE & 5GE to the Test
This White Paper examines the technical details of the new 2.5 & 5.0GE speeds and then presents Xena’s new Odin-10G-5S-6P-CU test module which can test both the new speeds plus 100Mbit/s, 1GE and 10GE.
