Eco-Sustainable System and Network Architectures for Future Transport Networks

Technology analysis indicates that silicon technology evolution will not be able to catch up with future global Internet traffic growth rates. As a result, current network and system designs as well as network architectures may need to be revised significantly. This paper provides a detailed analysis of various network element types (e.g., IP routers, Ethernet switches, and synchronous optical network/synchronous digital hierarchy [SDH/SONET] switches) and their components with respect to power dissipation (C) 2010 Alcatel-Lucent.
