Description
Technical field
The present invention relates to EPON, be meant Notification Method and device that a kind of optical network unit state changes especially.
Background technology
EPON (PON; Passive Optical Network) is a kind of passive light access technology that a little arrives the multidrop topology structure that adopts; Wherein, Gigabit passive optical network (GPON, Gigabit-Capable Passive Optical Network) technology is important techniques branch in the PON family, and this patent is the processing that example is discussed emergency message among the PON with GPON.
The GPON system is by the optical line terminal (OLT of office's side; Optical Line Terminal), the optical network unit (ONU of user side; Optical Network Unit) and Optical Distribution Network (ODN; Opticai Distribution Network) forms, adopt the network configuration of point usually to multiple spot.
In the GPON system; The transfer of data of down direction (by OLT to ONU) adopts broadcast mode; Each ONU receives all frames respectively; Obtain one's own frame according to ONU-ID (ONU sign), GEM (GPON Encapsulation Method, GPON method for packing)-Port ID (port-mark) and Allocation-ID (allocation identification) again.Yet, for the transfer of data of up direction (from ONU to OLT) owing to will share transmission medium, therefore need through suitable control and treatment just can make each ONU the upstream data information completely be sent to OLT.Uplink frame adopts time division multiplexing to insert (TDMA; Time Division Multiple Access) technology; This technology adopts up channel is divided into a plurality of time slots; ONU sends the report of sending upstream data to OLT, and OLT is that ONU distributes upstream bandwidth and controls it in certain time slot transmission data according to the report of ONU or through flow monitoring.In the existing GPON technology; OLT is that the upstream bandwidth that ONU distributes is to carry transmission with the mode of bandwidth map bandwidth distribution structure (BWmap allocation structures) through the downlink physical controll block (PCBd, Physical Control Block downstream) of downlink frame.
In order to realize the part management function of OLT to ONU; The G.984.3 standard definition of ITU-T physical layer operations management maintenance (PLOAM; Physical layer Operations, Administration and Maintenance) passage, GPON utilizes PLOAM channel transfer PLOAM message; Realization comprises that to the management of transmission convergence layer ONU activates, foundation, encryption configuration and the key management etc. of ONU management control channel.PLOAM message is transmitted in uplink frame (ONU sends to the frame of OLT) and downlink frame (OLT sends to the frame of ONU); Comprise a PLOAM message in each downlink frame; Whether OLT can send PLOAM message through the bit 10 notice ONU in the Flags territory of bandwidth map bandwidth distribution structure in the downlink frame in this upstream bandwidth; The value of said bit 10 is 1 o'clock; ONU sends PLOAM message in the corresponding upstream bandwidth of said allocated bandwidth, the value of said bit 10 is 0 o'clock, and ONU can not send PLOAM message in the corresponding upstream bandwidth of said allocated bandwidth.
Consider the energy-conservation demand of PON system; Propose when ONU does not have upstream data to send, to enter into sleep state in the prior art; Be in dormant ONU closed portion or repertoire; Can select not respond OLT and distribute to the upstream bandwidth of oneself, promptly in OLT distributes to oneself upstream bandwidth, not send upstream data, to reach purpose of energy saving.OLT is in the regular distribution upstream bandwidth of dormant ONU, can send upstream data timely when realizing that dormant ONU wakes up.
The problem that this technology exists is; OLT regularly is in dormant ONU to all and distributes upstream bandwidth, if OLT distributes said upstream bandwidth for dormant ONU with the short cycle, when ONU is in sleep state and when not having upstream data to send for a long time; Above-mentioned upstream bandwidth distribution mechanism has been wasted upstream bandwidth; In addition, if be in the allocated bandwidth that dormant ONU does not respond OLT, possibly thought by mistake operation irregularity by OLT; If OLT distributes said upstream bandwidth for dormant ONU with the long cycle; Wake up when need sending upstream data when being in dormant ONU, above-mentioned upstream bandwidth distribution mechanism can not guarantee that said ONU obtains upstream bandwidth timely and sends upstream data.
Therefore, the informing mechanism that need provide a kind of ONU state to change so that OLT carries out the distribution of upstream bandwidth according to the state of ONU, reaches the purpose that can practice thrift upstream bandwidth, can make the ONU that revives from sleep state in time send upstream data to OLT again.But, the notification scheme that does not also have a kind of ONU state that can achieve the above object to change at present.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment technical scheme of the present invention is further set forth in detail.
Method of the present invention is applicable to multiple PON, like GPON, XGPON1, XGPON2, also is applicable to other TDMA PON, like EPON, 10GEPON etc.
The distribution method of upstream bandwidth of the present invention, as shown in Figure 1, comprise the steps:
Step 101, ONU informs that OLT self changes sleep state over to.
When ONU does not have the upstream data transmission and will change sleep state over to, inform OLT, and when sleep state, no longer respond the upstream bandwidth that is used to send uplink business data that OLT distributes.Method of the present invention relates to two kinds of upstream bandwidths: the one, share upstream bandwidth, and be used for ONU reports change from oneself state to OLT; The one, be used for the upstream bandwidth of ONU reporting uplink business datum.Concrete, will in follow-up step, describe.
Preferably; ONU can send a PLOAM message to OLT, carries the sign (ONU_ID) of this ONU in this message, and this type of message is 10000000; Show that this ONU notice OLT self gets into sleep state, and when sleep state, no longer respond the upstream bandwidth that OLT distributes.Certainly, type of message also can have other set-up mode, as long as OLT can confirm that ONU changes sleep state over to according to this type of message.
Can also carry ONU in the above-mentioned PLOAM message and get into the dormant time; Perhaps, do not carry when getting into dormant time, OLT can confirm as ONU with the time that receives PLOAM message and get into the dormant time.
ONU can also send ONU management control interface information or GEM frame notice OLT self entering sleep state to OLT; When adopting these two kinds of message, the ONU-ID of this ONU is carried in the ONU-ID territory of the uplink frame through comprising ONU management control interface information or GEM frame; Perhaps, OLT can obtain the ONU-ID of this corresponding ONU of this Port-ID according to the port id (port-ID) in ONU management control interface information or the GEM frame from this locality.
Can also carry ONU in ONU management control interface information or the GEM frame and get into the dormant time; Perhaps, do not carry when getting into dormant time, OLT can confirm as ONU with the time that receives ONU management control interface information or GEM frame and get into the dormant time.
Step 102:OLT storage changes the information of dormant ONU over to.
After OLT learns that ONU changes sleep state over to, obtain and store the ONU-ID of this ONU; Further, also can store ONU and get into the dormant time.
Before this ONU revived, OLT no longer was used in the upstream bandwidth that sends upstream data to its branch.
Step 103:OLT distributes one or more shared upstream bandwidths to ONU.
An OLT can administer a plurality of ONU, and this OLT distributes one or more shared upstream bandwidth to all ONU of its administration.And the ONU response that only is in non operating state should be shared upstream bandwidth.
The present invention is referred to as non operating state with sleep state and wake states; Relative, also related to the ONU of operating state in the method for the present invention, the upstream bandwidth that is used to send uplink business data that this type ONU can normal response OLT distributes.
In addition, the present invention can also distribute one be used for the upstream bandwidth that ONU registers activation to the ONU that all are in login state by OLT, here be treated to prior art, repeat no more.Mainly be that ONU to sleep state and wake states discusses among the present invention.
OLT can distribute one or more shared upstream bandwidths to ONU termly, and this shared upstream bandwidth is used for ONU and changes to OLT repayment state.Here, the change of ONU state is meant that ONU changes wake states over to from sleep state.
OLT also can distribute shared upstream bandwidth to ONU according to the order of network management system.
OLT distributes shared upstream bandwidth termly, therefore, can practice thrift upstream bandwidth to greatest extent.
OLT can will share upstream bandwidth distribution through the allocated bandwidth structure of bandwidth mapping in the downlink frame and give ONU.Wherein, Alloc-ID in the allocated bandwidth structure is 111111111110; Being used to indicate this shared upstream bandwidth to be used for ONU repayment state changes; Certainly the value of Alloc-ID also can have other set-up mode, is to be used for ONU repayment state to change as long as ONU can confirm to share upstream bandwidth according to the value of Alloc-ID; The value of StartTime is that the value of xx, StopTime is xx+y in the allocated bandwidth structure.
It is to be noted; OLT and ONU can as offered be used for the mode that notify status changes; Inform that through PLOAM message OLT self changes wake states over to like ONU; Then OLT need be provided with the value of the bit 10 in the Flags territory in the allocated bandwidth structure, and when being 1, expression ONU can send PLOAM message; When being 0, expression ONU cannot send PLOAM message.
ONU can also get into wake states through ONU management control interface information or GEM frame notice OLT self.
In addition, when ONU got into wake states through PLOAM message, ONU management control interface information or GEM frame notice OLT self, the indication territory of uplink frame was the value of standard acquiescence; In the GPON system, the value of StartTime is that the value of xx, StopTime is that xx+y representes: ONU sends PLOAM message, ONU management control interface information or GEM frame in the xx byte of uplink frame, stops to send in the xx+y byte, and the minimum value of y is 2; If be the XG-PON system; The value of StartTime is that the value of xx, Grantsize is that y representes: ONU accomplishes the transmission of PLOAM message in the xx byte of uplink frame; Perhaps begin to transmit ONU management control interface information or GEM frame in the xx byte, the byte number of transmission is Grantsize.
Step 104: after the ONU that is in non operating state receives and shares upstream bandwidth, inform that OLT self changes wake states over to and needs to send upstream data.
ONU selects a shared upstream bandwidth from one or more shared upstream bandwidths, to the change of OLT repayment oneself state.If ONU quantity is more; When having only a shared upstream bandwidth; May cause a part of ONU competition less than this shared upstream bandwidth; Then therefore ONU just can't, adopt and distribute the mode of a plurality of shared upstream bandwidths to address this problem to ONU in time to the change of OLT repayment oneself state.
The state that is in the ONU of non operating state changes the two kinds of situation that are divided into: the one, and after receiving shared upstream bandwidth, ONU revives, and changes wake states over to; The one, before receiving shared upstream bandwidth, ONU revives, and is in wake states.Can both of these case be thought that all ONU changes wake states over to from sleep state.
Based on the situation that above-mentioned ONU state changes, after the ONU that is in non operating state received and shares upstream bandwidth, resolving the value that obtains Alloc-ID was 111111111110, and then ONU confirms that this shared upstream bandwidth is used for ONU repayment state and changes; If ONU changes wake states over to, also need send upstream data from sleep state; After then this ONU waits for a random delay according to the value of StartTime; On this shared upstream bandwidth; To the PLOAM message that OLT sends Serial_Number_ONU by name, inform that OLT self changes wake states over to and needs the transmission upstream data, and carry the ONU_ID of self through this message; Further, this message can also be carried above-mentioned random delay, so that follow-up ONU is found range accurately.
The PLOAM message self of Serial_Number_ONU by name just can be carried above-mentioned random delay; Can certainly carry random delay to after other PLOAM message is expanded in the standard.
ONU can also inform that OLT self changes wake states over to and in the uplink frame that comprises said ONU management control interface information or GEM frame, carries ONU_ID, also can carry random delay through ONU management control interface information or GEM frame.
Further, ONU can also carry the time that self changes wake states over to from sleep state through PLOAM message, ONU management control interface information or GEM frame; Can certainly not carry, can OLT will receive the time of PLOAM message, ONU management control interface information or GEM frame this moment and think that ONU changes the time of wake states over to.
Step 105:OLT distributes upstream bandwidth to the ONU that changes wake states over to.
The upstream bandwidth that here distributes is to be used for transmission of uplink data.
OLT learns when ONU changes wake states over to and needs the transmission upstream data that three kinds of processing modes can be arranged:
Mode one, OLT obtain the ONU_ID of the ONU of state change; This ONU of storage gets into the dormant time before can obtaining thus; And,, then this ONU is found range if the sleep duration surpasses preset threshold value according to the sleep duration of this ONU of Time Calculation that changes wake states over to of this ONU; Obtain a balanced time delay and send to ONU, distribute upstream bandwidth for this ONU simultaneously; Otherwise, do not find range, directly distribute upstream bandwidth for this ONU;
Mode two,
OLT obtains the ONU_ID of the ONU of state change, need not judge the sleep duration, directly this ONU is found range, and obtains a balanced time delay and sends to ONU, is that this ONU distributes upstream bandwidth simultaneously;
Mode three, OLT obtain the ONU_ID of the ONU of state change, need not judge the sleep duration, also do not find range, and directly are that ONU distributes upstream bandwidth.
Wherein, be embodied as prior art, repeat no more here what ONU found range.
Step 106: after the ONU that is in wake states receives upstream bandwidth, change operating state over to, and on upstream bandwidth, send upstream data to OLT.
If find range, then ONU upgrades the balanced time delay value of self according to the balanced time delay of obtaining, and on upstream bandwidth, sends upstream data to OLT; If do not find range, then ONU directly sends upstream data to OLT on upstream bandwidth.
In order to realize said method, the invention provides the reporting system that a kind of optical network unit state changes, as shown in Figure 2, comprising: OLT and ONU, wherein:
OLT is used for distributing one or more shared upstream bandwidths to ONU;
ONU when being used to be in non operating state, informs that through said shared upstream bandwidth OLT self changes wake states over to by sleep state.
Said non operating state comprises: sleep state and wake states.
ONU is further used for, and before ONU distributes one or more shared upstream bandwidths, when confirming self not have the upstream data transmission and changing sleep state over to, informs that OLT self changes sleep state at OLT;
OLT is further used for, and distributes upstream bandwidth to the ONU that is changed over to wake states by sleep state;
Accordingly, ONU is further used for, and behind the upstream bandwidth that receives the OLT distribution, changes operating state over to, and on upstream bandwidth, sends upstream data to OLT.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.
