Resilient network design [Editorial ]

We know from traditional network management that the quality of a complex system built on different sub-systems is dictated by the quality of the weakest part. Nowadays our lives, businesses and many promising applications throughout the world depend on the availability of different parts of an interconnecting scheme, for example the global Internet and associated services. With so many long-term heavy investment programs and hopes already built, communities are now heavily reliant on the sustainability of a hugely complex networking system. Now that real use of these ever growing networks is expanding, and promising use and applications are on the horizon, we need much tighter reliability on each component from personal, local, national, international and global interconnecting networks.
