Clock frequency determining method and device for router card

A device for determining a clock frequency of a router card, comprising:

• a target average port traffic calculating unit, configured to perform step A, calculate an average port traffic of a target network node for each of neighboring network nodes by using a total to-be-served traffic and the number of ports of the target network node for each of the neighboring network nodes to obtain a plurality of average port traffics, select the highest average port traffic from the plurality of the 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;
• a clock frequency determining unit, configured to perform step B, determine a lowest clock frequency meeting a demand of the target average port traffic from preset clock frequencies based on a preset correspondence between the clock frequency and the traffic, and set 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;
• an updating unit, configured to perform step C, update 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 the 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
• a determining unit, configured to perform step D, determine whether there is the updated total to-be-served traffic higher than zero, and perform step A in a case that there is the updated total to-be-served traffic higher than zero.
