Description of Service
IPTV (Internet Protocol Television) is a system where a digital TV service is
distributed on a network infrastructure using the IP protocol.
The protocol DOCSIS / EuroDOCSIS uses the concept of service flows for traffic
transmitted between cable modem and CMTS. A service flow is a one-way packets flow
that provide a specific service quality. Traffic is classified in a service flow, and each
service flow has its own set of parameters, named QoS.
QoS (Quality of Service) are technologies that ensure the transfer of certain
amount of data at a time, ensuring a good quality of service.
