Triple Play Residential Services

A burgeoning new market exists for Ethernet in the aggregation of consumer triple -play services (see Figure 3). The aggregation network needs to be optimized to meet the demands of voice, video and high- speed Internet services, and above all it must be extremely scalable to support the kinds of subscriber numbers inherent in a consumer- oriented service. For this market, VPLS is used as an enabling under- lying technology in the network infrastructure to provide scalability and reliability. Traditional Ethernet would be constrained by the limited number of virtual LANs that can be supported with spanning tree protocol; VPLS overcomes these limitations.

“As a leading provider of ‘always- on’ services such as triple play for consumers, SBC is expected to deliver the highest levels of reliabil- ity and service availability. Alcatel’s new features enabling non-stop routing and non-stop services will help SBC to meet the high expecta- tions of our customers.”
