IxNetwork VE is designed to test the functional and performance testing of physical and virtual network infrastructure, capacity, scalability, and convergence using scaled protocol emulation and traffic. IxNetwork VE can emulate protocols for routing and switching, data center Ethernet, software-defined networking (SDN), broadband access, and industrial Ethernet. Provides comprehensive protocol coverage for routing/switching, multiprotocol label switching (MPLS), broadband access, data center networking, and SDN Powerful traffic generation and statistics engine including stateless L2-3 traffic and stateful L4-7 application flows Common IxNetwork user interface across both Ixia hardware and virtual products enables end-to-end virtual and hardware based testing from a single pane of glass VMs of the Ixia hardware components (virtual chassis, virtual load modules_ are software that is optimized for protocol emulation and traffic generation in a virtual environement Comprehensive platform support including standalone hypervisors (VMware ESXi and KVM) and OpenStack-based private clouds

Spirent TestCenter is an end-to-end testing solution that delivers high performance with deterministic answers. Service providers, NEMs and enterprises use it to test, measure and validate their networks and deploy services with confidence - from traditional performance testing to the rigorous analysis of Virtualization, Cloud Computing, Mobile Backhaul, and High Speed Ethernet.

The LinkSprinter Pocket Network Tester verifies the functionality of copper Ethernet links and identifies errors in less than 10 seconds. The tester reveals network connectivity status and port information while ensuring documentation for every link. The comprehensive AutoTester measures PoE voltage, performs a switch test, and confirms the DHCP server is running and responsive. The tester also verifies gateway/router, internal IP service, and cloud reachability. When paired with the secure Link-Live Cloud Service, the Network Tester automatically uploads results and allows annotation of results enabling job supervisors to easily manage the progress of deployment and troubleshooting tasks assigned to their team.

Get the most out of your network devices and diagnose potential issues with comprehensive performance testing. With a suite of powerful, yet easy-to-use tests that simulate a variety of typical traffic conditions, FortiTester lets you set performance standards and run audits to make sure your network continues to meet them. It also stores past tests for easy comparison. With the test results, you can take action to improve your network’s performance.

The ExtraHop Application Performance Management Solution Delivers Unified Visibility Across the IT Environment w/ Proactive Alerts & Accelerated Troubleshooting

To really understand what is happening to your applications, you need proactive visibility that spans your hybrid network. Alluvio NetProfiler uses full-fidelity network traffic flow monitoring to proactively identify and quickly troubleshoot performance and security issues. Easily answer bandwidth analysis questions like “How much traffic is being consumed?” “Who is using it?” “Where is it going?” and “How is traffic is being prioritized?” Alluvio NetProfiler provides network flow analytics that you can use to quickly diagnose network issues and identify security threats before end users ever know there’s a problem. NetProfiler combines network flow data with packet-based flow metrics to provide proactive monitoring, analysis, and reporting.
