From Alex Volinsky:
This enhancement implements dissector for Downstream DOCSIS (Data over Cable)
frames, embedded into MPEG packets and encapsulated into L2TPv3 over IP
(DEPI/D-MPT encapsulation). This type of encapsulation is used in Modular Cable
Modem Termination System (M-CMTS) architecture for head-end components that
comply with DOCSIS.
DEPI, the Downstream External PHY Interface, is the interface between the
M-CMTS Core and the EQAM. More specifically, it is an IP Tunnel between the MAC
and PHY in a Modular CMTS system.
L2TPv3 is described in RFC3931.
DOCSIS DEPI data packet transport mechanism is described CM-SP-DEPI-I03-060728
(Downstream External PHY Interface - CableLabs specification)
The format of MPEG packet carrying DOCSIS data is described in
CM-SP-DRFI-I07-081209 (Data-Over-Cable Service Interface Specifications -
CableLabs specification).
