Ethernet Traffic Generation and Analysis White Papers

PAM4 Auto-Neg & Link Training

Learn about Auto-Neg & Link Training on PAM4/NRZ and how Valkyrie can test these functions, together with Teledyne Lecroy's spectrum analyzer.

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.

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.

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.

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.

Time Synchronization

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

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.

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.

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.

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.

Quality Assurance Testing

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

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.

OpenFlow®

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

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.

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.

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.

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.

DDoS

Going beyond generating DDoS traffic, Xena’s solutions can help companies test their security products and operators test networks and detect flaws, thereby ensuring business continuity and preserve business integrity.

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.

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.

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.
