Abstract: With the appearance of new protocols and services,the traditional routers with rigid and exclusive structure can't meet the upper services' development An open and reconfigurablc muter with functional evolution is needed. This paper put forward a systematic structure of reconfigurable muter, which is based on an assembly mechanism like building blocks. With multi-vector mapping,this structure takes advantage of changing vectors to realize the variable functions, update, add, or delete its original functions. The muter with evolutionary function will support the diverse upper services' development effectively.
