Lag is frustrating for subscribers using interactive, real-time applications such as streaming services or video games. These users will switch providers if they don't receive the quality experience they expect. Lag is also difficult to manage, as it varies depending on whether IP traffic is moving upstream or downstream. Consequently, CSPs must be able to reliably measure unidirectional latency to identify the direction of degradation and the location of excessive or uncontrolled delays.
“This ability to easily and cost-effectively measure one-way delays without requiring expensive external timing systems or GPS seems crucial for more accurately measuring network latency,” said Alan Breznick, head of cable/video activities at Light Reading. “Such an approach can offer a far superior way to ensure the best possible subscriber experience.”
“Customers demand more bandwidth, better coverage, and predictable service performance. To meet these demands, CSPs need a robust network latency management strategy,” said Claudio Mazzuca, vice president of systems and services at EXFO. “EXFO’s standards-compliant measurement algorithm is easy to deploy. There is no equipment to install, maintain, or upgrade, resulting in both operating and capital cost savings.”
