This device would be called a packet generator, but would act as both generator and analyzer-at the same time and in the same “box” (see Figure 1). This has traditionally been achieved with a single testing device acting as both transmitter and receiver. To test a network connection, a significant amount of traffic must be created, transmitted through the System Under Test (SUT) and analyzed on the other end. Read on to learn more about what we have discovered. How should the infrastructure in use be tested? How can network performance be measured reliably in a cloud environment? Our R&D team decided to modify existing TRex solution a little in a way that pps, latency, jitter and reordering can be measured between separated nodes. ![]() But that does not mean there are not serious challenges in going cloud. It is all very appealing, and modern, and intelligent. ![]() It is an obvious choice for building large, distributed systems from scratch, as well as for the many enterprises migrating their infrastructure and services to the cloud. It is probably the cloud that first comes to mind when you think about the architecture of modern services.
