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.
