With development of network scale and hardware

router solution project based on Traffic Engineering has been more and more poprlar.And in the Traffic Engineering solution project

Traffic Engineering dynamic routing is an important part.So

we have analysed the current situation

and presented TE dynamic routing math model

which takes bandwidth and hops into account and presents routing rules.In the end

by the computer simulation

we validate the feasibility of the routing and advantage of the current shortest path priority routing.
