K=L*h；
Wherein, K is the PON mouth flow threshold of OLT, and the PON cause for gossip survey handling capacity that L is OLT, h is peak factor, 0 < h < 100%, peak factor is at least used to determine the reasonable threshold value of current network.
Illustratively, the business demand bandwidth of current network carrying increases, and repeatedly service traffics increase within a short period of time, Therefore, we can determine peak factor according to actual measurement situation.
Illustratively, the value of h can be by acquiring one or more PON mouthfuls of the mean flow of the OLT in a period of time Acquisition is calculated after measuring α and peak flow β；
H=α/β；
Wherein, α is the average flow rate of the PON mouth of OLT, and β is the peak flow of the PON mouth of OLT.
Optionally, peak factor can be 65%, then according to the PON of OLT mouth downlink throughput capacity (actual measurement downlink throughput capacity) It can be concluded that the PON mouth flow threshold of OLT, as shown in table 1 below, handling capacity unit Mbps.
The PON mouth flow threshold example of table 1:OLT
Choosing actual measurement downlink throughput capacity is that will cause loss due to environmental factor, long distance transmission etc., and peak factor is chosen 65% is determined based on current network conditions, and 65% actual measurement downlink throughput capacity is different port type in network in table 1 Flow threshold；FTTH (fibre (fiber) to the home, fiber to the home), FTTB (fiber to the building, Fiber to the floor), EPON (ethernet passive optical network, Ethernet passive optical network), GPON (gigabit capable PON, gigabit passive optical network), XG-PON (10gigabit capable PON, ten gigabits Passive optical network), 10G EPON (10gigabit ethernet passive optical network, ten gigabit ether Net passive optical network).The OLT of different systems corresponds to the PON mouth of different systems.The PON mouth of OLT refers to the end on the PON board of OLT Mouthful, commonly referred to as PON mouthfuls.EPON, PON standard its i.e. corresponding OLT that GPON, 10G EPON, XG-PON are current main-stream Port standard.EPON network, that is, EPON standard PON network, and so on.
Illustratively, above-mentioned equipment 101-107 step acquisition relevant parameter and export corresponding result is executed, can be clothes Business device, such as network management system are also possible to other terminals, such as PC.
108, when the PON mouth total flow of the estimated OLT of determination is more than or equal to the PON mouth flow threshold of OLT, according to default rule The method of drawing plans broadband network.
Illustratively, when the PON mouth total flow W of the estimated OLT PON mouth flow threshold K for being 7000, OLT is 6950, i.e., 7000 > 6950, it needs to plan network at this time.
In the embodiment of the present application, it first obtains broadband network parameter and handling capacity is surveyed in the PON cause for gossip of OLT, joined according to network Number, determines broadband user's Mean Speed, so that the PON mouth total flow of estimated OLT is obtained, when the PON mouth total flow of estimated OLT is big When handling capacity is surveyed in the PON cause for gossip of OLT, planning processing is carried out to network, it can realize and determine when to need based on service traffics Planning processing is carried out to physical network, so as to plan in time broadband network, promote wideband user service experience.
In a kind of achievable mode, as shown in Fig. 2, being carried out to broadband network in 108 steps according to presetting planing method Planning, specifically includes:
1081, judge whether the PON mouth total flow of estimated OLT is more than or equal to the PON mouth flow threshold of OLT.
When the PON mouth total flow of estimated OLT is less than the PON mouth flow threshold of OLT, 101 steps are executed；As estimated OLT PON mouth total flow be more than or equal to OLT PON mouth flow threshold when, execution 1082 steps.
1082, whether the specification for judging OLT is maximum specification.
When the specification for determining OLT is maximum specification, 1083 are executed；When the specification for determining OLT is not maximum specification, hold Row 1084.
Illustratively, as shown in table 1, in the network of FTTH and FTTB access at present, OLT maximum specification is 10G PON output The OLT of port, that is, judge OLT port whether be 10G PON standard port, it should be noted that with advances in technology, OLT can also further develop, update, and not be defined herein to the standard of OLT.The portion OLT of the following 25G, 50G PON After administration, this method also can be used.
1083, the first planning instruction is sent to management terminal.
Wherein, the total splitting ratio for the ODN that the first planning instruction is at least used to indicate OLT connection at least needs to reduce by one etc. Grade, the first planning instruction can be to be generated according to data, is also possible to pre-stored, the application is not particularly limited；Institute The primary number of fibers in main line that the total splitting ratio for stating ODN is ODN is divided by the user side branch optical fibers total quantity of ODN；The main line of ODN Primary optical fiber is the optical fiber for the PON mouth that ODN is used to connect local side OLT, and usual quantity is 1；The user side branch optical fibers of ODN are ODN is used to connect the optical fiber of the PON mouth of user side ONU；It should be noted that total splitting ratio of ODN reduces a grade, reduce A grade determine according to the actual situation, can be and 1:32 is reduced to by 1:64, be also possible to be reduced to 1 by 1:64: 48, the application is defined not to this.
Illustratively, according to professional standard, planning guide/guidance, the secondary light-splitting of the ODN network of a PON mouthfuls of connections The splitting ratio of device is identical, and in this case, total splitting ratio of ODN is the product of the splitting ratio of optical splitters at different levels, any level light splitting The splitting ratio of device is the splitting ratio of any of any level optical splitter optical splitter, point of each optical splitter in any level optical splitter Light is than identical.
Illustratively, in the presence of there was only level-one optical splitter in ODN, total splitting ratio of ODN is the light splitting of level-one optical splitter Than when level-one optical splitter in ODN and secondary light-splitting device exist simultaneously, total splitting ratio of ODN is equal to the light splitting of level-one optical splitter Than the splitting ratio multiplied by secondary light-splitting device.
