Triple-Play Service Deployment

Chapter 2: Triple-Play Service Delivery over Ethernet Networks
In a triple-play offering, Ethernet, as an aggregation network over
which converged voice, video, and data travel,must deliver carriergrade
performance. This is particularly important as it relates to
transport network characteristics, such as packet loss and jitter,
while maintaining the following attributes:
– Rapid scalability, resiliency, and redundancy
– Five-nines of reliability (99.999%)
– Ability to meet key network SLAs (Connectivity, Throughput,
Packet Loss, Packet Jitter, and Delay)
– Cost-effective deployment of high bandwidth services
– Convergence of business, residential, and wireless services
Even with these significant challenges, demand for Ethernet
aggregation networks is increasing. This, coupled with the
providers’ rapid adoption and evolution of triple-play services and
service delivery mechanisms, is mitigating the implementation of
new provisioning and service assurance strategies to address
increasingly complex networks and customer expectations.
Providers understand they can ill-afford to have customer
satisfaction issues resulting from poor video service (with quality
problems such as pixelization), dropped VoIP packets (affecting
voice quality), slow Internet connections, or any other number of
problems that may be caused by the Ethernet aggregation
networks. Thus, the traditional quality assurance methodologies,
test tools, and processes are insufficient for maintaining and
understanding true end-to-end QoS for triple-play services.
Providers are seeking solutions that will allow them to efficiently
install, troubleshoot, maintain, and analyze services, without
sacrificing the quality of experience.
