Testing and analyzing network and application performance

Application speed and user experience depending on network speed, delays, and various interference factors. Challenges are often generously accused of ‘networking’. Really persistent updates to applications, updates to infrastructure, security-related deviations, and intermittent interaction of 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 network capacity, speed, and problems affecting them. The analysis uses special tools to enable quick and accurate analysis as the basis for network development, validation of new network technologies, and assurance of the capacity and prioritization promised by the service operator (SLA and QoS). 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 around 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 enables network engineers to resolve problems that would otherwise live on in the system 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 be continued at the service level to the protocol level, where appropriate, and efforts will be made to optimize the entity together with stakeholders.
