A. The major difference between DOCSIS 1.0 and DOCSIS 1.1 is that DOCSIS 1.0 uses Service ID (SID) to identify cable modems and the devices behind them, while DOCSIS 1.1 uses service flows. DOCSIS 1.1 also has improved MAC framing features, improved provisioning, and authorization with advanced Baseline Privacy Interface Plus (BPI+ ) features. Service flows are the fundamental units in DOCSIS 1.1 for QoS provisioning. DOCSIS 1.1 allows multiple service flows per cable modem. This means that different types of traffic, such as data, voice, and video, can be separately identified on the same cable modem. This separate identity provides specialized QoS treatment as per traffic needs.
