The problem of OSPF routing protocol flooding algorithm on redundant multi-links is discussed. An enhanced flooding algorithm based on selected interface is provided.
In this thesis, we also discuss the mechanism of Flooding and Pruning in Dense-Mode multicast routing protocol and the process of switch from RPT to SPT in Sparse-Mode routing protocol.
According to the comparisons with flooding algorithm and ideal routing condition by simulation, this algorithm has obvious advantages in receiving rate and energy saving.
