Performance Testing

Test. Improve. Repeat.

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.

EXAMPLE OF USE

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.

CASE STORY

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.

… relevant for this type of testing

Microburst

Microbursts – where data packets are transmitted in rapid bursts – can lead to periods of full line-rate transmission that overflow packet buffers of the network stack. This can seriously impact network performance but the problem is difficult to detect.

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.

G.fast

G.fast is a next-gen DSL technology designed to seriously boost signal speeds to customer premises. Learn how Xena test solutions can be used to verify G.fast performance and conformance with Broadband Forum ID-337.
Xena Networks

Testing 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.

100G PON

Xena's Valkyrie platform made it easy for BT to verify the performance of their new 100G PON solution. PON is an access network technology that ensures high-speed network access to business and private users.

SD-WAN

SD-WANs make it easier to centrally manage WANs spread across a wide area. Learn how Xena's traffic generation and analysis solutions are used to test and verify SD-WANs.

Time Synchronization

Learn how ValkyrieTimeSynch is used for synchronizing test instruments in different locations using GPS, PTP and NTP.

Transport Layer Security

Discover how Xena's Vulcan platform can be used to reveal performance bottlenecks of TLS/HTTPS middleboxes/proxies, meet security performance testing requirements, and optimize security parameters.

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.

Application Emulation

Testing with realistic network traffic places the device under test (DUT) in a realistic network environment and delivers authentic results.

Advanced Layer 4 Replay

Xena Advanced Layer 4 Replay provides stateful replay on top of its high-performance TCP stack, high scalability for performance verification and preserve correlation information across sessions for true emulation.

VSPerf

This White Paper explains how Xena is working with the Open Platform for NFV (OPNFV) community on the vSwitch Performance (VSPerf) project towards a generic architecture-agnostic vSwitch performance benchmarking and test framework.

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.

400GE

Learn about the new PAM4 400GE & 200GE data rates and how to verify the performance of network equipment capable of handling the new speeds.

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.

Emulation vs. Simulation for Layer 4-7

Testing with realistic application emulation is about emulating network traffic that contains realistic traffic patterns and content. Which is essential for providing guaranteed Quality-of-Service (QoS), and high degrees of Quality-of-Experience (QoE).

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.

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.

OpenFlow®

Learn about OpenFlow performance testing and how Xena's Valkyrie platforms are used to verify OpenFlow performance of switches in SW-defined networks.

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.

NGFW Performance

Different from deploying new NGFW into pre-production networks, when the firewalls are in fact up and running in the production networks, any upgrade should be handled carefully.

Autoneg & Link Training

Discover how Xena's Thor-400G-7S-1P test module supports auto-negotiation and link training for PAM4 data rates up to 400GE.

IP Multicast

Learn about IP multicast and how Xena’s test solutions are used to verify IP multicast and IGMP performance in accordance with RFC 3918, and perform multicast stress testing and IGMP snooping verification.

Testing NGFWs

To rigorously test the performance of next generation firewalls (NGFWs), it is no longer enough to bombard them with dummy traffic.
