Abstract:


The Cisco ServiceFlex design defines the network layer of the Cisco IP NGN architecture, which provides the ability to treat each service with optimal transport mechanisms, thereby providing efficiency, reliability, superior quality of experience, and adaptability to future services. Cisco ServiceFlex is a service-aware network layer architecture that supports essential service attributes at both Layer 2 and Layer 3, making it an optimal design to converge residential and consumer services.

The Cisco ServiceFlex design enables service providers worldwide to deploy IP data, voice, and video services to a broad array of customers – including residential and consumer, commercial and business, and education and government – using DSL, Fiber to the Premises (FTTP), and Ethernet access. This means that service providers can now economically use existing last-mile copper facilities – either owned or leased – and aggregate triple-play services over a cost-effective Ethernet or Multiprotocol Label Switching (MPLS) transport. As network infrastructure continues to migrate toward optical facilities, the same architecture can easily adapt to accommodate a provider’s needs. Cisco ServiceFlex provides consistent end-to-end QoS, security, and high-availability models that service providers can use to build diverse service-level agreements (SLAs) for their customers.

The Cisco ServiceFlex design works with the last-mile access technology methods including:

bullet

DSL access for residential services

bullet

Ethernet to the Home (ETTH) for residential services

bullet

Ethernet to the Business (ETTB) using copper or fiber access for business-based services

 

Occam components allow the addition of FTTx access technology in the last mile while providing ADSL2+, T1, and Ethernet connectivity options.
