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.
The new White Paper dives into the technical details. Called "Terabit Ethernet - How", it covers how Ethernet speeds beyond 400Gbps require changes to the Ethernet physical layer as well as the implications for first movers in this pre-IEEE standardization phase.
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.
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.
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.
Any organization that produces Ethernet networking components will perform a variety of performance, functionality, and quality of service tests. While many of these tests take place at the R&D stage, companies that ...
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.
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.
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.
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.
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.
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).
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.
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.
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.
This White Paper explains why Ethernet impairment testing is crucial in deploying 5G fronthaul networks, and highlights the protocols that need particular attention when optimizing your equipment or application performance in 5G fronthaul networks.
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.
