Solutions to test and validate NAT routers for performance and functionality

Automotive Ethernet Testing

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.

Time Synchronization

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

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).

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.

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.

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.

Quality Assurance Testing

How Valkyrie can be used for Quality Assurance testing of Ethernet products up to Layer 3.

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.

Transport Layer Security

Discover how Vulcan reveals performance bottlenecks of TLS/HTTPS middleboxes/proxies, meets performance testing requirements, and optimizes security parameters.

OpenFlow®

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

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.

The Case for 25GE & 100GE

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.

Quality of Service Validation

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.

Traffic Generator Upgrade

Learn how to extend the capabilities of your Valkyrie traffic generation and analysis solution using a L1 Matrix from CGS Tower Networks.

Application Emulation

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

The Shared Lab Challenge

Learn more about how a Lab-as-a-Service solution will give users of shared labs an efficient and seamless way to utilize shared lab resources improving both CapEx and OpEx.
