On the other hand, some of the most significant problemswith the Internet today relate to lack of sufficient tools fordistributed management,especially in the area of routing.In the large intemet being currently operated, routingdecisions need to be constrained by policies for resourceusage. Today this can be done only in a very limitedway, which requires manual setting of tables. This iserror-prone and at the same time not sufficientlypowerful. The most important change in the Internetarchitecture over the next few years will probably be thedevelopment of a new generation of tools formanagement of resources in the context of multipleadministrations.
