ComplexityNetworks keep moving towards ever increasing complexity New services added every week!

New technologies added every month!New architectures introduced every year!Combining the old with the new (no replacement!)

ComplexityWhere are "ever increasingly complex" networks heading?

Something needs to be done ...Open systems people need to do something ...

Solution: introduce an autonomic behavior to provide an automatic configuration.

EnergyThe TCP/IP protocol over wireless is consuming a lot of energy.TCP/IP is not a good protocol for wireless networks.

TCP/IP is a protocol for “rich” networks and not for “poor” networks.
