With more and more subscribers and the growing data load on packet networks, service providers have to cope with heightened performance pressure. Loss and latencies are daily occurrences but the impact of these network events has very different effects on User Datagram Protocol (UDP) traffic as compared to Transmission Control Protocol (TCP) traffic. Contrarily to UDP, TCP performance is greatly impacted by loss and latency as well as incorrect configurations. This is why service providers have to struggle to effectively and correctly troubleshoot TCP performance issues or qualify TCP performance at activation.
This webinar discusses TCP performance and EXFO’s ExacTCP methodology designed to address TCP testing challenges.
