Data Plane
Challenge: Identify and develop building
blocks reusable in different architectures
3
Data Plane
•
Provides mechanisms for efficient
communication and processing of data
•
Examples:
–
Network protocols (e.g., MAC)
–
Database query processing (merge, filter, ...)
–
Signal processing (compression, detection,..)
{
Integration

Control Plane
•
Provides services for network set up and
maintenance in dynamic environments
•
Examples:
–
Self-organization
–
Routing
–
Localization

Management Plane
•
Provides tools for managing network elements
and monitoring the network
•
Network programming
–
Automated
–
Scalable
–
Secure
•
Network monitoring: links, energy, node status,
data dissemination…
–
How to monitor a network without significantly
disrupt its operations?
•
Example: Network observation system
