The Equal Longest Path First Reboot -- Rebooting Network Edge Switches in a Campus Network --
Motoyuki Ohmori, Masayuki Higashino (Tottori Univ.) IA2018-29
Abstract (in Japanese) (See Japanese page) 
(in English) Even in the era of Software Defined Network (SDN) or Software Defined Infrastructure (SDI), network edge switches still requires to be rebooted for some reasons, e.g., updating a firmware, configuring a special behavior and so on.
It may be necessary to clarify how ones can shorten a downtime of a campus network when many switches in the network require reboots.
To this end, this paper expresses a campus network in a graph theory fashion, and contracts the graph by vertex contraction.
This paper then presents how to compute a depth of a vertex by a matrix computation.
This paper then proposes the procedure, the equal longest path first reboot, that minimizes a downtime of a network.
This paper then introduces a prototype implementation of the proposed method, and evaluates the proposed method in an actual campus network.
This paper also presents that the proposed method can minimize a downtime on the same level of the ideal minimal downtime.
