Technical Applications notes for Ethernet Testing

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 Valkyrie traffic generator to function as a basic DHCP server.

Scheduling Modes

This application note explains the four scheduling modes.

High-speed Port Configuration

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

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.

Time Synchronization

This application note describes how the TimeSynch option provides time synchronization for Xena Networks ValkyrieBay and ValkyrieCompact test chassis.

Testing SyncE

How to use Xena’s Advanced Timing test modules to demonstrate network synchronization, and to perform go/no-go testing of SyncE networks.

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.

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.

TCP Throughput Testing

This Application Note describes how to make RFC 6349 based TCP throughput tests with the Xena Networks layer 4-7 test solution VulcanBay controlled by VulcanManager.

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.

Sequence Error Detection

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

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.

Network Interfaces For CFPT Testers

The CFP transceiver form factor can provide network interfaces supporting both 100 Gbps, 40 Gbps, and 10 Gbps Ethernet interfaces. This application note explains how Xena’s CFP based 100/40/10 Gbps Ethernet testers can provide network interfaces for each of these speeds.

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.

Measuring Network Convergence

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

Measuring Frame Delay Variation

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

HW Modifiers in Valkyrie2544

How to add two HW modifiers to a protocol header field in Valkyrie2544

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.

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.

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.

Central Office Testing

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

DDoS Testing with ValkyrieManager

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.

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 Valkyrie2544.
