Effects of User Activity on Broadband CPE Throughput (Video)
Tags: Performance

Broadband users are demanding. A sudden change in the subscriber experience means support calls or shopping for new devices. QA teams often test to ensure line-rate throughput, but how does a device perform over time? How does it perform when other devices connect to it, disconnect, and make or request configuration changes? How do you more »


Our training guides give you an overview of how to correctly implement and test the common protocols used in today’s CPE devices.
