ROFL : restoration of failures through link-bandwidth sharing

Résumé

Due to the advancement of new access technologies such as the 4G-LTE, WiMAX, etc. leading to high bandwidth demands at the access network part, it becomes ever more important today to find innovative new methods of re-designing the backhaul architecture of telecommunication networks, since even a transient link/node failure within the backhaul could lead to enormous congestion. That said, in this paper, we introduce a novel fault restoration scheme through link-bandwidth sharing among different mobile network operators (MNOs). We begin by demonstrating the availability of wireless communication networks supported by microwave backhaul links while two different MNOs share their working paths as an alternative for backup paths. This will help in tackling the high bandwidth requirements apart from serving as a backup under link failure situations without any additional cost investments. We proceed further towards a probabilistic model for fault restoration to reroute traffic flows in the event of link failures while two different MNOs share their backhaul link-bandwidth.
