line cost

An arbitrary positive integer value assigned to a physical path. Because the routing algorithm selects the least-cost path toadestination, an operator can dynamically affect the path to be taken by changing line costs.; 為物理路徑指定的任意正整數值,由于路由選擇算法總是選定最廉價的到達目的地的路徑,操作人員可以通過改變線路費用來 動態地影響所選定的路徑。
