Full Reversal in a Partitioned Network A B F C E G D In the partition disconnected from destination D, link reversals continue, until the partitions merge Need a mechanism to minimize this wasteful activity Similar scenario can occur with partial reversal method too 136
Temporally-Ordered Routing Algorithm (TORA) [Park97Infocom] TORA modifies the partial link reversal method to be able to detect partitions When a partition is detected, all nodes in the partition are informed, and link reversals in that partition cease 137
