Cn X. Wang et al. 1007/978-3-642-54174-2_5, © Springer-Verlag Berlin Heidelberg 2014 47 48 W. Wu et al. Interestingly, reliable and efficient network reboot is not addressed sufficiently in the literature. Most real-world systems rely on network flooding to issue the reboot command. Network flooding can hardly guarantee 100 % reliability. A few malfunctioned nodes may cause severe performance degradations to the entire network. To ensure a high reliability in practice, flooding the reboot command requires a significant number of broadcasting messages.
