2. DOCSIS Networks for Internet Access
 More than 56 million
DOCSIS cable modems
(CMs) are deployed
worldwide

 Cable operators want to
use the same Operations
and Support Systems
(OSS) with other access
network technologies (i.e.,
EPON)

5.  Brings the mature systems and business processes of
the DOCSIS OSS to EPON access networks
 Enables full vendor/equipment interoperability – similar
to CMTS and Cable Modems
 Leverages existing technical and customer care
knowledge base, systems, and processes
 Developed by MSOs, CableLabs, and vendors

6. DPoE Project Objectives
Develop specifications for EPON devices to support
1 DOCSIS network provisioning and service concepts
Define additional functionality to support Ethernet
2 services
Facilitate multi-vendor interoperability

8. Provisioning DPoE ONUs
Authentication and
IP Initialization
Encryption Initialization
• Downstream encryption • IP stack configuration using
using AES‐128 Dynamic Host
• Device authentication Configuration Protocol
(DHCP)
• TFTP download of
configuration file
Topology Resolution and Registration
Physical Layer Initialization
• Registration of additional
• Initial MAC layer
LLIDs depends on services
initialization using EPON
• Classifier, service flow, and
Multipoint Control
QoS configuration using
Protocol (MPCP)
extended OAM (eOAM)
• Single LLID is registered for
subsequent stages

10. SIEPON “Packages”
 SIEPON is standardizing
three “packages”:
o North America (Package A)
o Japan (Package B)
o China (Package C)
 External specifications
provide additional
requirements for operating
EPON in specific
environments:
o DPoE specs for DOCSIS
environments
o Broadband Forum for DSL
environments

11. SIEPON / DPoE v1.0 Relationship
 DPoE specs essentially build on SIEPON standard
