Testing and analyzing network and application performance
Application speed and user experience depend on network speed, delays, and various interference factors. Challenges are often generously accused of ‘networking’. Really persistent application updates, infrastructure updates, security-related deviations, and intermittent interactions from rogue applications that have appeared on the network cause problems online. In addition, the SD-WAN service layer, intelligent routing, and various tunneling techniques also present additional challenges for troubleshooting. Finding them is challenging and requires expertise and specialized tools.
Testing and analyzing the performance of a corporate network gives the company a good understanding of its capacity, speed, and any issues affecting it. The analysis uses specialized tools to enable quick, accurate assessments that support network development, validate new network technologies, and ensure the capacity and prioritization promised by the service operator (SLA and quality of service). The analysis is based on packet data.
Packet data vs NetFlow
Packet data has been the gold standard for network visibility ever since the first packet analyzer was invented. The common expression among network analysts is, “packets never lie.” Packets show what is really happening on the wire, detailing all the protocols, conversations, and timing involved in network communications. Collecting packets and getting the real wireline story enable network engineers to resolve problems that would otherwise persist indefinitely.
Right analysis tools get more value from your network. Packets provide an unprecedented level of visibility, filling gaps that other technologies, such as NetFlow, leave wide open.

The analysis will continue from the service level to the protocol level, where appropriate, and efforts will be made to optimize the entity in collaboration with stakeholders.
