IP NGN Carrier Ethernet Design

Service providers around the world 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. The objective of this paper is to provide an overview of Cisco recommendations for designing IP Next-Generation Network (NGN) Carrier Ethernet networks. The Cisco IP NGN Carrier Ethernet Design provides a network infrastructure that is scalable, flexible, and oriented toward new service delivery. In order to meet new business challenges, service providers must have sufficient flexibility in the network infrastructure to scale current services and quickly enable new services.
