This application note explains the four scheduling modes.

How to test AN/LT protocol and performance

As the use of 112G PAM-4 SerDes becomes widespread, the need to test Auto-Negotiation & Link Training (AN/LT) increases. Learn how to test AN/LT protocol implementations using Xena's FreyaCompact ANLT Test Appliance and Xena OpenAutomation (XOA).

How to use break-out cables on Xena Chimera

Discover the full potential of Xena Chimera's 5 speeds impairment

Sequence Error Detection

This Application Note explains how the detection works and how this is shown in the test results.

HW Modifiers in Xena2544

How to add two HW modifiers to a protocol header field in Xena2544

Gauges - Meters

This application note describes how Xena test results can be presented in gauges, using Graphite and Grafana installed in a virtual Linux machine.

Freely Programmable Test Packets (Custom Data Fields)

This application note explains how you can use the Custom Data Field (CDF) and Extended Payload features in selected Xena high-speed test modules to compose a wide variety of test packets to test the DUT.

DHCP IP Assignment

Don’t want to add a DHCP Server to a test environment? Here is some simple scripting that lets you use a Xena traffic generator to function as a basic DHCP server.

PCAP Replay

This application note describes how to make your or PCAP file that conform to Vulcan’s replay engine, and how to use Vulcan’s replay scenario to scale up the traffic for high-performance testing.

Concurrent Connection and Connection Per Second Testing

This Application Note describes how to test these three critical performance parameters for a firewall: TCP CC, TCP CPS, and throughput against different packet sizes.

High-speed Port Configuration

This Application Note describes what can be achieved with the modules and describes various topics related to this context.

Stress Testing Switches and Routers

This application note describes how to use a Xena tester to perform a simple stress test on a Layer-2 device’s data plane and forwarding capability.

Central Office Testing

This application note examines the characteristics of an Ethernet tester in the central office environment.

Minimum IFG Testing

The Xena testers can verify traffic forwarding performance, protocol scalability and services delivering capabilities of switching and routing devices across the enterprise, metro/edge and core.

Testing with Speed Compensation

The Xena testers can verify traffic forwarding performance, protocol scalability and services delivering capabilities of switching and routing devices across the enterprise, metro/edge and core.

Measuring Frame Delay Variation

How to measure FDV accurately and in real time using Xena Networks testers.

Evaluating 1588v2 Performance

This Application Note describes a test plan for evaluating the performance of both Boundary clocks (BCs) and Transparent clocks (TCs) based on solutions from Calnex and Xena Networks.

Testing 100G Ethernet

This application note looks at the challenges of testing 40 and 100 Gbps Ethernet. As with any new technology, the key to success is testing, and 40/100G Ethernet brings a new set of issues to the development cycle.

Wholesale Ethernet Service testing

The Xena testers enable wholesale Ethernet service providers to very cost efficiently perform service activation for enterprise customers by providing a highly scalable gigabit Ethernet test platform ideal for installation in network edge central office locations.

Measuring Network Convergence

How testing your network’s re-convergence time with industry leading measurement precision simplifies measuring the operations of resiliency mechanisms.

VSPerf RFC 2544 Throughput

How to benchmark and characterize virtual switch throughput performance for telco Network Functionality Virtualization (NFV) use cases (under the project VSPerf) - using Xena2544.

DDoS Testing with XenaManager

DDoS is defined as multiple compromised systems – usually infected with a Trojan – are used to target a single system causing a Denial of Service (DoS) attack. This Application Note explains step-by-step how to test your switches' behavior under such conditions.
