Project Goal
 Need to resolve the challenges facing today’s Internet by
rethinking the fundamental assumptions and design
decisions underlying its current architecture
 Currently, a major research effort has been initiated on the
topic of Clean Slate design of the Internet’s architecture
 Management issues of Future Internet also need to be
considered from the stage of design
 Thus, we will define management requirements &
operations of Future Internet
 Writing a survey paper:
Towards Management of Future Internet

Architecture (1)
 Keywords
– Virtualization
• Virtualizes network resources and provide customer-specific
services
– Service-oriented architecture
• Defines layer’s functions as services and converge the
services to support the network operations
– Cross-layer design
• Divides network layers and support cross-layer mechanism

 Research Efforts in Europe
– EuroNGI WP.JRA.1.5 Network Management: New trends and
Architectures
• Location management
• Mobility management
• Management architecture
– Special Joint Specific Research Project (JRA.S.06): Design and
Evaluation of Distributed, Self-Organized QoS Monitoring for
Autonomous Network Operation (AutoMon)
• Specify a distributed, self-organizing and autonomic IP QoS
monitoring framework which is based on Distributed Hash Tables
• Evaluate the performance of the peer-to-peer mechanisms for
maintaining the monitoring overlay
– European network on MANagement solutions for the Internet and
Complex Services (EMANICS)
• Joint Research: Scalable management, Economic management,
Autonomic management
