Abstract

Provided are a method and a device for determining a clock frequency of a router card. The method includes steps A to D. In step A, a target average port traffic is obtained by using the number of ports and a total to-be-served traffic higher than zero of a target network node for each of neighboring network nodes. In step B, a clock frequency meeting the demand of the target average port traffic is determined as a clock frequency of any router card, the clock frequency of which has not been set, in the target network node. In step C, the total to-be-served traffic and the number of ports are updated. In step D, step A is performed, in a case that there is the updated total to-be-served traffic higher than zero.

step A, calculating an average port traffic of a target network node for each of neighboring network nodes by using a total to-be-served traffic and a number of ports of the target network node for each of the neighboring network nodes to obtain a plurality of average port traffics, selecting a highest average port traffic from the plurality of average port traffics as a target average port traffic, wherein the target network node is any one of network nodes in a network, and the total to-be-served traffic is higher than zero;
step B, determining a lowest clock frequency meeting a demand of the target average port traffic from preset clock frequencies based on a preset correspondence between a clock frequency and a traffic, and setting the lowest clock frequency as a clock frequency of any router card, the clock frequency of which has not been set, of a router in the target network node;
step C, updating the total to-be-served traffic and the number of ports, wherein a first calculating result is obtained by subtracting a service traffic of the router card, the clock frequency of which has been set, corresponding to the neighboring network node from the total to-be-served traffic of the target network node for the neighboring network node, and the first calculating result is determined as an updated total to-be-served traffic of the target network node for the neighboring network node; and a second calculating result is obtained by subtracting a number of actual ports of the router card, the clock frequency of which has been set, corresponding to the neighboring network node from the number of ports of the target network node for the neighboring network node, and the second calculating result is determined as an updated number of ports of the target network node for the neighboring network node; and
step D, determining whether there is the updated total to-be-served traffic higher than zero, and performing step A in a case that there is the updated total to-be-served traffic higher than zero.
