Embodiment 1,
As shown in figure 3, embodiments herein provides a kind of flow diagram of network expansion method, the network capacity extension
Method is applied in communication network as shown in Figure 1.The network expansion method specifically includes:
S301, bandwidth status on single direction is determined according to having been carried out bandwidth and bandwidth is not carried out on single direction.
The connection of each level is divided into multiple and different directions, and specific Metropolitan Area Network (MAN) connection direction divides such as table 1: Metropolitan Area Network (MAN) is each
Direction detail list.
Table 1
Judged by having been carried out bandwidth to single direction and bandwidth being not carried out, can accurately be identified in this direction
Bandwidth status.Illustratively, whether the bandwidth after can implementing by comparing the bandwidth and last capacity expansion project of current Metropolitan Area Network (MAN)
It is identical, if they are the same, then prove that last engineering is all finished, the bandwidth status of Metropolitan Area Network (MAN) is to have been carried out bandwidth.If it is different,
Then indicate that last engineering is not implemented all, the bandwidth of current Metropolitan Area Network (MAN) is the part that last engineering has been carried out, and should will be worked as
The bandwidth status of the sum of bandwidth of preceding Metropolitan Area Network (MAN) and the unenforced bandwidth of last engineering as Metropolitan Area Network (MAN) avoids ignoring with this
The unenforced part of phase engineering carries out repeating dilatation waste caused by resource.
Specifically, user can be by single in the applications client or networking client of operating terminal 30 input table 1
The corresponding number information in direction, to generate the network capacity extension request to the direction.The applications client or network of operating terminal 30
Client forwards network capacity extension request to network capacity extension device 20, and network capacity extension device 20 is receiving the transmission of operating terminal 30
Network capacity extension request after, the single corresponding number information in direction in identification request, and obtain the single direction of this in Metropolitan Area Network (MAN) 10
Have been carried out bandwidth, the information such as bandwidth, present flow rate and existing configuration port number be not carried out.
S302, the flow on single direction is obtained according to bandwidth status and the progress volume forecasting of the present flow rate in single direction
Prediction result.
Specifically, determining whether the ratio of present flow rate and bandwidth status on single direction is greater than or equal to the first threshold
Value carries out volume forecasting to the single direction for being greater than or equal to first threshold and obtains volume forecasting result.
By judging whether the ratio of the present flow rate and bandwidth status in some direction is greater than or equal to current period capacity expansion project
First threshold, to determine whether the direction can be with the network capacity extension.If being less than first threshold, then it is assumed that without in special circumstances, be somebody's turn to do
Pattern bandwidth is not necessarily to dilatation.If more than or be equal to first threshold, then the carry out volume forecasting to the direction avoids unnecessary
Bandwidth dilatation improves the reasonability of prediction result.Illustratively, first threshold can be 40%, if single direction is current
Flow is 80G, and when bandwidth status is 100G, the ratio of present flow rate and bandwidth status is 80/100=0.8 > 40%, then it is assumed that
The single direction can carry out the network capacity extension, carry out volume forecasting to the single direction.
S303, the target port number in single direction is obtained according to volume forecasting result, bandwidth status and port granularity.
Specifically, determine whether the ratio of volume forecasting result and bandwidth status is greater than or equal to second threshold, to being greater than
Or the single direction equal to second threshold, the target bandwidth in single direction, root are obtained according to volume forecasting result and second threshold
The target port number in single direction is obtained according to the target bandwidth and port granularity that meet preset condition.Wherein, port granularity
It is used to indicate the amount of bandwidth of single port, preset condition can be the target bandwidth in single direction and the object tape of Correspondent Node
Width is identical.
It is whether identical by the target bandwidth in the single direction of verifying and the target bandwidth of Correspondent Node, it is upper and lower to guarantee with this
The target bandwidth of demand is consistent, avoids logic error occur when network capacity extension demand calculates.
Illustratively, second threshold can be 70%, and port granularity can be 10GE.If the flow on single direction is pre-
Survey result is 98G, and bandwidth status is 100G, and the ratio of direction volume forecasting result that you can get it and bandwidth status is 98/100
=0.98 > 70%, therefore the direction needs to carry out dilatation, then according to volume forecasting result and second threshold it can be concluded that the party
To target bandwidth be 98/70%=140G, then verify Correspondent Node target bandwidth whether be 140G, if the communication of opposite end
Bandwidth is also 140G, then according to target bandwidth and port granularity it can be concluded that the single direction needs 140/10=14 a, i.e.,
The single direction at least needs 14 ports.
S304, according to total, the existing configuration port number of the target port number in all single directions, to offline port
Number allots the port number to reuse and the port number of single board determines board number to be expanded.
Wherein, existing configuration port number can be the total quantity of port configured on all boards, to offline port
Number can be the total quantity being not used or need offline port according to the actual situation on all directions, allot the port to reuse
Number can be the total quantity for the port that can be called according to the actual situation.
According to total, the existing configuration port number of the target port number in all single directions and to offline port number
Determine port dilatation demand number.
According to port dilatation demand number and allots the port number to reuse and determine actual port demand number.
If actual port demand number is less than or equal to 0, show that existing port number is sufficient for this network capacity extension pair
The demand of port carries out the network capacity extension without additional board.
If actual port demand number is greater than 0, additional board is demonstrated the need for carry out the network capacity extension, it at this time can basis
The port number of actual port demand number and single board determines board number to be expanded.
Illustratively, if the sum of the target port number in all single directions be 20, existing configuration port number 11,
It is 1 to offline port number, alloting the port number to reuse is 6, and the port number of single board is 5, then port dilatation needs
Seeking number is 20+1-11=10, and actual port demand number is 10-6=4, and board number to be expanded is 4/5=0.8 block, i.e., originally
In the secondary network capacity extension, 1 piece of board of dilatation is at least needed.
By having been carried out on single direction bandwidth and bandwidth is not carried out in network expansion method provided in an embodiment of the present invention
Determine the bandwidth status on single direction, volume forecasting carried out according to bandwidth status and present flow rate, according to volume forecasting result,
Bandwidth status and port granularity obtain the target port number in single direction, further according to the target port in all single directions
Several, existing configuration port number is determined to offline port number, the port number for alloting the port number to reuse and single board wait expand
The board number of appearance.Bandwidth status is determined to guarantee that existing bandwidth is more accurate, in conjunction with stream by having been carried out and being not carried out bandwidth
Amount prediction screening needs the direction of dilatation, summarizes the port dilatation demand number of all directions, and calculate the to be expanded of actual demand
Board number realizes the accurate dilatation to network with this.
