Alcatel-Lucent 5750 SSC - Manual (Page 4)

Triple-play service delivery — blend -
ing voice, video and data services in
an integrated service bundle — is a
generational leap that carries with
it certain challenges.
• Today’s Internet service-delivery
networks are optimized for flat-rate,
best-effort commodity services.
With the advent of triple play,
high-revenue services such as inter -
active multimedia applications, VoIP,
VoD and broadcast TV (BTV)
become the dominant network-
design drivers. These services place
unprecedented scalability, reliability,
flexibility and QoS requirements
on the IP-network infrastructure.
• New user devices such as residen -
tial gateways (RGs), IPTV set-top
boxes, IP phones and gaming con -
soles are being intro duced in the
digital home network and must be
managed and con trolled. Fiber-to-
the-node (FTTN) and fiber-to-the-
Challenges and Opportunities of Triple-Play Service Delivery

user (FTTU) access technologies,
a shift from ATM to Ethernet-based
service aggregation, IP/MPLS serv -
ice routing, IP multi cast, and on-
demand session-admission con trol
are driving oper ational support
requirements for which legacy
systems were not designed.
• While transforming to a converged,
multiservice IP infrastructure, ser -
vice providers need to leverage and
migrate strategic assets from the
installed base of TDM voice and
high-speed Internet (HSI) services
to effectively up-sell existing sub -
scribers to a triple-play offering.
This migration needs to be non-
disruptive for the service provider
and transparent to subscribers by
allowing legacy service features
to be seamlessly ported to the
next-generation network (NGN)
infra struc ture while minimizing
operational impacts and costs.
Beyond a profound network transfor -
mation, a centralized and reliable
subscriber-management and policy-
control infrastructure is required to
enable millions of triple-play sub -
scribers and end-user devices to
securely access and use network-based
applications, services and content
with assured quality of experience.
The Alcatel-Lucent 5750 SSC is
purpose-built to address these needs.
The system enables service providers
to be optimally positioned to success -
fully conduct network and service
transformation to converged triple-
play service delivery and unlock its
full revenue potential.
