Network Infrastructure Performance Testing
The Network Performance Test feature (NPT) of the OptiView XG allows users to test and troubleshoot high performance links across wide area networks, campuses, or within data centers and to remote sites. Engineers managing enterprise or service provider networks now have a single tool for measuring network infrastructure performance and troubleshooting complex network problems. NPT quantifies the performance of the network in terms of bandwidth, latency, jitter and loss up to line-rate 10 Gbps, giving engineers solid data about the capabilities of their infrastructure and its ability to support current and future applications.
Service providers and system integrators can use OptiView XG to validate layer 2 services and provide "value added" support of customer enterprise networks, from troubleshooting performance problems to conducting network assessments and new technology rollouts, such as VoIP and video.
Enterprises can use OptiView XG's Network Performance Testing to:
- Troubleshoot network infrastructure performance problems
- Assess network performance prior to deployment of new services such as video or VoIP
- Validate the performance of new infrastructure elements and critical links within their data center
- Independently determine if their service providers are meeting Service Level Agreements (SLAs) and maintaining QoS end-to-end
- Find the location of performance bottlenecks with Graphical Path Analysis
- Bi-directional testing, from operational levels (for troubleshooting) up to full line-rate 10 Gbps (for validation)
- Programmable streams of up to eight simultaneous flows with independent upstream/downstream SLA parameters including Committed Information Rate, Committed Burst Size, Excess Information Rate, Excess Burst Rate, and Frame Sizes
- Flexible Layer 2 and Layer 3 settings including source and destination MAC and IP addresses, VLAN settings, TOS with DSCP or IP precedence, UDP port number and frame contents
- Complete setting of Service Acceptance Criteria limits for availability, throughput, frame loss, delay, and jitter (delay variation)
- Thorough reporting with pass/fail indication based on Service Acceptance Criteria
Network Performance Test User Interface
Path Analysis Testing Pinpoints Network Failure Points
While other tools can send traffic over the network, and may tell you there is a problem, only OptiView XG can test for problems AND show you the location of the issue. Graphical Path Analysis shows the complete layer 2 and layer 3 paths across your network, displaying the health of switches and routers along the path of the data flows in real time – while NPT tests are underway – allowing you to instantly see overloaded or errored interfaces, discarded packets, CPU and memory-utilization issues, or even devices rebooting. This allows instant diagnosis of bottlenecks along the data path for quick resolution.
Graphical Path Analysis Pinpoints Network
Bottlenecks During Performance Tests
Use NPT's multi-stream capability to generate different flows of traffic with different QoS and rates to determine if your network can support new or additional traffic like VoIP and video.
Detailed Results with Clear Pass/Fail Indicators
Class of Service
The Network Performance Test features the ability to generate streams of various Layer 2 (VLAN priority) and Layer 3 (TOS with DSCP or TOS with Precedence) traffic, validating the ability of your network (and service provider's network) to maintain QoS from end to end. Generating different traffic rates at different QoS settings allows the testing of traffic prioritization, ensuring that high priority traffic is treated as such throughout your network.
Validate Service Provider SLAs
When applications are slow over internet or WAN links, the blame game is only just beginning. With NPT and OptiView XG, enterprises don't have to rely on service provider metrics, but can test and validate SLAs and net capacity directly. End the finger pointing and know you're getting what you paid for by generating your own performance reports.
Test and validate SLAs
Validate Data Center Performance with Full-Duplex Testing at 10 Gbps
By pairing two OptiView XG's together, or with the OneTouch™ AT 10G Network Assistant, you can fully test 10 Gig links with independent upstream/downstream flow rates, up to full line-rate 10 Gbps. The independent management port allows complete control without impacting tests. You've invested a great deal in high-performance network hardware – ensure that you are getting the results you expected.
A "Good – Better – Best" strategy for instrumenting your network
Windows® Reflector agent – "Good"
Travelling to remote sites, whether across town or across the country, is time-consuming and inefficient – the more problem-solving engineers can do from their desk, the more effective they can be. When troubleshooting remote user-performance problems, you need deeper visibility into what the user is actually experiencing in order to get to root cause.
The OptiView XG Windows Reflector agent is an easily-downloadable software agent for instant deployment on PCs anywhere in your network, for performance testing and troubleshooting wherever it is needed. Simply direct your remote user to point their web browser at OptiView XG's IP address, then download and install the small footprint application. Then, target the user's PC with OptiView XG's Network Performance Test to get a fast reading of roundtrip throughput, packet loss, jitter, and latency. Combine that with Graphical Path Analysis to visually see where performance issues might be hiding.
The agent provides symmetric upstream/downstream flow rates up to approximately 900 Mbps to a PC connected via a 1 Gbps NIC. Actual performance can vary based on the performance of the client's operating system and TCP/IP stack. Importantly, the agent can also be used on PCs connected via Wi-Fi, allowing troubleshooting of performance through the wired AND wireless infrastructure.
Note: The Windows Reflector supports Windows 7, Windows 8, Windows 10 and Windows Server 2008 R2, both 32- and 64-bit editions.
LinkRunner™ – "Better"
The LinkRunner™ AT 2000 with Reflector Option acts as a remote device for symmetric upstream/downstream flow rates up to line-rate 1 Gbps over copper or fiber. An economical alternative for hardware-based endpoints, using this tool as a hardware reflector at critical sites throughout your network provides an "always on" means of testing and troubleshooting performance and service provider SLAs anytime. Using LinkRunner provides a "known standard" instrument for performance testing that is not impacted by the performance of the client's operating system, or TCP/IP stack. Equipping remote sites with LinkRunner units to be used as needed for performance testing is good practice, but another benefit is that having them onsite also equips local frontline technicians with simple tools for solving user connectivity problems.
OneTouch™ AT 10G Network Assistant – "Much Better"
The OneTouch™ AT 10G Network Assistant allows bi-directional testing (asymmetric, up to 4 separate, simultaneous streams) at up to full line-rate 10 Gig on copper or fiber. Whether used at 1G or 10G rates, bi-directional testing is essential for assessing a network's capacity for voice and video traffic. The OneTouch AT 10G provides a cost-effective way of instrumenting multiple points in the network with a 10G device for performance testing, network assessment, and validation of critical, high-performance links.
When not used for performance testing, the OneTouch AT 10G can be used by network technicians for basic troubleshooting of 10G links. The AutoTest feature completes an hour of testing in about one minute. An AutoTest is a set of tests tailored to your network, services, and applications. It can be simple with only a few tests or advanced consisting of dozens of tests. Once created, an AutoTest can be saved for quick and easy reuse later. Use it to establish best practices for consistent, faster, more productive troubleshooting and network acceptance testing.
The instrument comes with both copper (100/1000/10G) and fiber (1/10GBASE-SR, 850 nm multimode SFP+) network interfaces. Alternatively, different SFP+ modules may be used for different standards/distances (LR, LRM).

When not used for performance testing, engineers at the remote site have the most powerful tool available for local wired and wireless troubleshooting, assessment, mapping and more.
Unmatched Network and Application Performance Analysis
OptiView XG is at home in the data center, with support for 10 GbE and virtualized servers; at the users' office supporting 802.11a/b/g/n/ac and application analysis; and with the switches and routers in between. Use it to find problems from your desk or take it with the data it collected to the trouble spot for first-hand analysis. Its unique troubleshooting system is based on proactive analysis, path analysis, and application-centric analysis, which provides expert guidance that automatically identifies the root cause of problems. No other tool combines powerful performance testing with in-depth troubleshooting and analysis.
More Flexible and Powerful than Other Testing Methods
Based on ITU-T Y.1564, the newest standard for testing real-world Ethernet performance, OptiView XG's NPT provides enhanced performance compared to older standards such as RFC 2544, including:
- Faster—the LRPT option measures all key performance Service Level Criteria (SLC's)—availability, throughput, frame loss, delay, and delay variation (jitter)—in a single test instead of multiple independent tests.
- Fixed Test Times—a single lost frame during an RFC 2544 throughput test requires it be run again, so a test may take many times its set length. ITU-T Y.1564 tests only need to run one time for a complete measurement.
- More thorough—measures additional key Service Level Agreement (SLA) requirements including Excess Information and Excess Burst Rates (EIR/EBR), and availability. Measures delay and jitter on every frame in the test.
- More flexible—supports multiple simultaneous flows with independent destinations, SLAs and SLCs, CoS and VLAN settings.
