DOCSIS testing should include stateful two-way interactive flows. To measure true quality of experience or service satisfaction require a ‘Per flow’ test approach in which stateful CPE traffic is presented on the cable modem to CPE Interface. This allows you to test performance on an end-to-end basis from the CMCI (Cable Modem to CPE Interface) to CMTS-NSI (Cable Modem Termination System – Network Side Interface). Performance testing includes everything from DHCP, IPv6 CPE behavior, QoS effectiveness and the upstream/Downstream channel bonding capability.
Shenick diversifEye “Per-Flow” Test System can deliver these capabilities. This PDF is an overview of how diversifeye can help you with your testing requirements.
