Abstract:


Service providers worldwide agree that the Carrier Ethernet and IP/Multiprotocol Label Switching (MPLS) technology will pave the way to next-generation networks; however, there are multiple approaches to designing Carrier Ethernet networks. This paper provides an overview of recommendations from Cisco for designing an IP Next-Generation Network (NGN) Carrier Ethernet infrastructure.

Service providers are facing increasing challenges brought on by service convergence and stiff market competition. To maintain growth and profitability, service providers need to:

bullet

Accommodate surging demand for broadband services

bullet

Maintain competitive residential and business service offerings

bullet

Avoid service commoditization by offering new and premium services

bullet

Strengthen profitability by increasing revenue while reducing total cost of ownership

bullet

Migrate existing ATM/Frame Relay to more cost-effective Carrier Ethernet service

bullet

Protect and grow business services in parallel with consumer services


The Cisco IP NGN Carrier Ethernet Design supports these business goals with five essential attributes: convergence, resiliency, intelligence, scalability, and manageability.

The Cisco IP NGN Carrier Ethernet Design facilitates a converged network infrastructure that cost-effectively delivers new and future services. This network infrastructure supports the bandwidth and network requirements for Broadcast TV Video (BTV) and video-on-demand (VoD) services, among others. All network services are fully supported, including:

bullet

Consumer and residential services

bullet

Business services

bullet

Broadband mobility services

bullet

Wholesale services


Using the Cisco IP NGN Carrier Ethernet Design, service provider organizations can transport profitable services in a consistent and reliable manner, providing a high quality of experience (QoE) to an entirely new generation of subscribers.
