Benefits
DOCSIS 1.1 includes a rich set of features that provide advanced and flexible QoS capabilities for various
types of traffic (voice, data, and video) over the cable network. It also provides enhanced security and
authentication features.
Baseline Privacy Interface Plus Enhancement
The Plus (+) version of the Baseline Privacy Interface (BPI+) in DOCSIS 1.1 provides a set of extended
services within the MAC sublayer that increase performance and system security. Digital certificates provide
secure authentication for each cable modem, to prevent identity theft on the basis of MAC and IP addresses.
Advanced encryption provides a secure channel between the cable modem and CMTS, and secure software
download allows a service provider to upgrade the software on cable modems, without the threat of interception,
interference, or alteration of the software code.
Dynamic Service Flows
The dynamic creation, modification, and deletion of service flows allows for on-demand reservation on Layer
2 bandwidth resources. The CMTS can now provide special QoS to the cable modem dynamically for the
duration of a voice call or video session, as opposed to the static provisioning and reservation of resources at
the time of cable modem registration. This provides a more efficient use of the available bandwidth.
Concatenation
The cable modem concatenates multiple upstream packets into one larger MAC data frame, allowing the cable
modem to make only one time-slot request for the entire concatenated MAC frame, as opposed to requesting
a time slot for each packet. This reduces the delay in transferring the packet burst upstream.
Enhanced QoS
Extensive scheduling parameters allow the CMTS and the cable modem to communicate QoS requirements
and achieve more sophisticated QoS on a per service-flow level.
