we believe that multipath routing and traffic dispersion have some benefit 
in network security, reliability and, perhaps, performance. 
But I am not quite sure whether today's IGPs are able to find several possilble
paths at a time and how difficult it is to be implemented, including
balance loading algorithms. would someone 
draw a light on the trade-offs of such a scenario? 
thank you.
