For testing TLS performance, it is essential that the test equipment can send encrypted TLS traffic through the DUT while it is operating in the TLS middlebox/proxy mode. This White Paper examines how Xena TLS reveals performance bottlenecks of TLS/HTTPS middleboxes/proxies, addresses security performance testing requirements, and optimizes security parameters.
Some applications can tolerate traffic delays, jitter and a degree of traffic loss – others cannot. 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.
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.
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.
This White Paper examines the background for IP multicast and then looks at how Xena’s test solutions can quickly and cost-effectively test and verify IP multicast and IGMP performance in accordance with RFC 3918, and perform multicast stress testing and IGMP snooping verification.
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.
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.
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.
Time synchronization of test instruments far apart is required to make one-way latency measurements and multi-site protocol analysis. This White Paper explains how synchronization of time in test instruments can be achieved with GPS, PTP and NTP. ValkyrieTimeSynch can use all 3 to synchronize time for Xena stateless testers.
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.
Software-defined Wide Area Networks (SD-WANs) bring the ability to centrally manage WANs over a wide geographical area and are especially valuable for enterprises with large number of branches or data centers. This White Paper examines the challenges of testing and verifying SD-WAN solutions.
This White Paper demonstrates how the goals listed above can be achieved using Xena’s stateless traffic generator on configurations orchestrated by CNLabs NFV Test Framework. The open source firewall pfSense is used as the Virtual Network Function.
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).
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.
Expanding the capabilities of a Xena traffic generator typically requires investing in extra test modules to access more ports, different speeds and so on. However, in some instances, a L1 Matrix can be used to defer such investments. This White Paper examines the various options for upgrading your Xena traffic generator.
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.
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.
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.
Learn more about essential OpenFlow performance tests and how Xena Networks stateless test platforms provide the features needed to quickly and cost-effectively test and verify the OpenFlow® performance of switches in the SDN.
