Optimality principle in routing algorithm
Web5.2Routing Algorithms(2) • There are two processes inside router: a) One of them handles each packet as it arrives, looking up the outgoing line to use for it in the routing table. This process is forwarding. b) The other process is responsible for filling in and updating the routing tables. That is where the routing algorithm comes into play. WebThe optimality principle has its dual form: in a continuous or discrete process, which is described by an additive performance criterion, the optimal strategy and optimal profit are …
