Abstract
The invention discloses a method for increasing the OLT (optical line terminal) utilization rate. The method comprises six steps as follows: Step 1, to-be-tested ONTs (optical network terminals) are collected, and a test begins; Step 2, a plug-in Server end of an OLT records the ONTs undergoing a flow test; Step 3, when the total bandwidth is smaller than the upper bandwidth limit of a PON (passive optical network) port, the OLT utilization is unsaturated, and a program at the Server end permits all test end requests; Step 4, when the total bandwidth is larger than the upper bandwidth limit of the PON port, the OLT utilization is saturated, the Server end notifies a test end of suspension and ending of the test; Step 5, the test end requests test starting again after receiving a suspension and ending notification; Step 6, after the flow test is ended, the test end sends a test ending notification, and the Server end subtracts the corresponding PON port bandwidth occupation condition. The method is used for increasing the OLT utilization rate.
Description
Technical field:
The present invention relates to a kind of method improving OLT utilance.
Background technology:
Along with the development of science and technology, network is more and more universal, and people are by shopping at network, game, search, chat etc., also more and more higher to the requirement of bandwidth.Optical-fiber network then becomes the market mainstream with its high transfer rate, and therefore fiber to the home also becomes market mainstream solution.
Along with fiber-to-the-home universal, Optical Network Terminal ONT (Optical networkterminal) production capacity becomes quick growing trend, and during plant produced ONT, to the performance test of ONT mainly through being registered to by ONT in optical line terminal OLT (Optical LineTerminal), measure the transmitting-receiving bag-like condition under nominated bandwidth.Because gigabit network interface is more and more universal, for ensureing the product quality of ONT, flow rate test standard is at least set to more than 100,000,000, therefore in theory, the ONT quantity that the upper gigabit PON mouth of OLT can be measured simultaneously is fewer and feweri, due to the restriction of bandwidth, a gigabit PON of OLT generally can only test 2-4 sheet ONT simultaneously.
Factory, when producing ONT, for ensureing enough production capacities, just needs to purchase OLT device in a large number, because OLT device is general more expensive, causes larger cost pressure to production enterprise, how to improve OLT device utilance and becomes the problem that production link must solve.
Summary of the invention:
The object of this invention is to provide one to be controlled by program, coordinate OLT resource, reasonable arrangement production process, reach a kind of method improving OLT utilance promoting OLT utilance.
Above-mentioned object is realized by following technical scheme:
Improve a method for OLT utilance, this method comprises six steps, and the first step collects ONT to be measured, starts test; The Server end that second step OLT is plug-in, record is just at the ONT of flow rate test; 3rd step to be less than on PON port band width in limited time when total bandwidth, and OLT utilizes unsaturation, and Server program of holding is let pass all test lead requests; 4th step is prescribed a time limit when total bandwidth is greater than on PON port band width, and OLT utilizes saturated, and Server notifies the test lead test EOT end of timeout; After 5th step test lead receives the notice of the EOT end of timeout, request starts test again; 6th step test lead after flow rate test terminates sends and terminates test notice, and Server deducts corresponding PON port band width and takies situation.
A kind of described method improving OLT utilance, the described first step collects ONT to be measured, first start test is, employee does not need to pay close attention to the ONT quantity of testing, only need ceaselessly to collect ONT to be measured, and power on, plug optical fiber cable and netting twine, hit testing end test program starts test, initiatively can send test flag information and hold to the server be contained on OLT after test program starts test.
A kind of described method improving OLT utilance, described second step OLT plug-in Server end be record just at the ONT of flow rate test, and calculate ONT and take situation at corresponding PON port band width, and add up testing ONT bandwidth occupancy situation under each PON mouth, collect the bandwidth demand of request for test, and tired note is in bandwidth consumption simultaneously; PON bandwidth upper limit comparison therewith in real time.
A kind of described method improving OLT utilance, the 4th described step is prescribed a time limit when total bandwidth is greater than on PON port band width, and OLT utilizes saturated, and Server notifies that the test lead of last-minute plea suspends test, until have ONT to test under this PON mouth, Server notifies the test lead test EOT end of timeout.
Beneficial effect:
1. the present invention really only accounts for about 1/4th of the whole operating process time for the flow rate test time, and the theoretical registrable ONT quantity of OLT can reach more than 64 or 64, the ONT of registration far more than treating quantitation, can reach the effect improving OLT utilance.
2. employee's operation of the present invention and ONT registration very do not take OLT resource, by development sequence, flow rate test process and employee's operating process and registration process can be carried out reasonable distribution, reach OLT and carrying out optical tests flow always, reach the effect of the utilance improving OLT.
