Description
Technical field
The present invention relates to the communications field, in particular to the preferential sending method of a kind of operation management maintain message, Apparatus and system.
Background technology
Along with the high speed development of information technology, network has become requisite instrument in people's routine work and life.Ethernet passive optical network (Ethernet Passive Optical Network, referred to as EPON) technology combines the advantage of Ethernet and EPON (Passive Optical Network, referred to as PON), becomes a kind of important technology of Access Network.EPON system mainly comprises local side apparatus optical line terminal (Optical Line Terminal, referred to as OLT) and terminal equipment optical network unit (Optical Network Unit, referred to as ONU).Local side apparatus must have the ability detection business, physical link between network and the local network of users and some important informations of equipment are provided.Operation management maintain message (Operation Administration and Maintenance, be called for short OAM) information addresses this is that exactly, and OAM data must be in time, preferentially send.
In traditional E PON technology, a corresponding LLID of ONU (Logical Link Identifier, referred to as LLID).But along with the develop rapidly of IT technology, being on the increase of application type, the ONU of single LLID may can not well distinguish a large amount of emerging service types.The EPON of China Telecom technology, for the ease of the management of multiple queues in ONU, is set up the more mapping relations of polymorphic type business simultaneously, therefore each ONU is expanded to 8 road LLID.Because single channel LLID has had the function of distinguishing different kinds of business according to data label (TAG), therefore the design of 8 road LLID can significantly increase the type of application layer service data, thereby support a greater variety of application services, provide more careful, efficient service quality (Quality of Service, referred to as QoS) to ensure.
Fig. 1 is the flow chart that sends data according to the ONU of correlation technique, and as shown in Figure 1, this transmission flow comprises the following steps:
Step S102, sends report frame;
ONU, by data volume size to be sent, sends to OLT with Report frame report form.
Step S104, distributes time window;
OLT, according to the report value of the Report frame receiving, analyzes time window (Grant window) size of corresponding ONU.
Step S106, sends data.
The Grant window size that ONU distributes according to OLT, sends existing data.
Fig. 2 is the flow chart that sends data according to the OAM of single LLID of correlation technique, because Report frame in existing agreement is at most only supported to 8 queues, must ensure efficient QOS simultaneously, so user will expect to support to 8 queues when in use.OAM data just must be mixed with other business datum like this, send at service queue.As shown in Figure 2, this transmission flow comprises the following steps:
Step S202, sends report frame.
ONU, by OAM data to be sent, with the data in same queue, reports to OLT with the form of Report frame together.As shown in Figure 2 a, a Report frame is supported 8 queues to concrete reporting format: queue 0, queue 1 etc.
Step S204, distributes time window.
OLT, according to the report value of Report frame, distributes corresponding Grant window size to corresponding ONU.
Step S206, sends OAM data.
The Grant window size that ONU distributes according to OLT sends to OLT by OAM data together with other data.Fig. 2 b is according to the transmission schematic diagram of the OAM data of correlation technique, and as shown in Figure 2 b, the data in 8 queues of Report frame, through dispatching after (schedule, referred to as Sche), become an output queue and send.
From above-mentioned process of transmitting, OAM data can not send to OLT in the very first time.Specifically, if OAM data are not stored in highest-priority queue, OAM data can not send in the very first time certainly.If OAM deposit data is in the queue of limit priority, in the time having other business datums in same queue, ONU can first send other business datums, then could send OAM data.
In addition, in the process of equipment work, should ensure the service quality of QOS, expect that OAM data can send the most in time simultaneously.But in correlation technique, only 1 road LLID is sent to OAM data, and can not ensure that OAM can preferentially be sent out away.
For ensureing the problem that OAM data can preferentially send in correlation technique, effective solution is not yet proposed at present.

The embodiment of the present invention is used as the OAM data in OAM queue as the data in highest-priority queue, with the report value that generates highest-priority queue together with business datum in highest-priority queue.Then generate Report frame and send to OLT according to the report value of highest-priority queue and other 7 service queues.In newly-generated Report frame, only have 8 queues, the Report frame that OLT receives also only has 8 queues.Concrete Report frame format as shown in Figure 6, in figure using queue 0 as highest-priority queue, certainly highest-priority queue can be also any one queue in 8 service queues, new queue 0 is generated by OAM queue and former queue 0 reconstruct, other queues remain unchanged, like this, Report frame or formed by 8 queues, but reconstruct of data in OAM queue is in queue 0.The requirement that the present invention does not just run counter to EPON agreement like this.
OLT distributes time window and sends to this OLT for this OLT according to received Report frame.
In the time that ONU gets the time window information of OLT, this time window information is the window size of a LLID, and there is no the window size of concrete queue, so when ONU sends, can dispatch according to 9 queues.When transmission, adopt strict priority scheduling mode.Specifically, in having OAM data, send at first the OAM data in OAM queue.In there is no OAM data, send the business datum in original 8 service queues.Business datum in these 8 service queues sends according to original scheduling mode, and it does not have any impact to OAM data.Concrete send mode as shown in Figure 5.OAM data, always receiving after the authorized window of OLT, just can send like this.That is to say, OAM data sent in the very first time.
Fig. 7 is that as shown in Figure 7, this flow process comprises the following steps according to the flow chart of the OAM high priority data sending method of single LLID of the embodiment of the present invention:
Step S702, arrives special OAM queue by OAM deposit data.
OAM deposit data is arrived to special OAM queue, according to the report value of the Data Update highest-priority queue in OAM queue and highest-priority queue, Report frame highest-priority queue and remaining 7 service queue after by reconstruct form like this, and Report frame is still made up of 8 queues.The Report frame that ONU acquires OLT sends when license, and this Report frame is sent to OLT.Now, the report value of highest-priority queue in Report frame, is to have comprised OAM size of data.
Step S704, distributes time window.
The report value of the Report frame that OLT sends according to ONU, distributes to the LLID time window size that this ONU is corresponding.In current agreement, there is no the time window size of concrete queue, only have total size of the time window of whole LLID.
Step S706, preferentially sends the OAM data in OAM queue.
ONU gets after the time window of OLT, checks 9 queue situations of LLID, sends OAM data according to the scheduling mode of strict priority (Strict Priority is called for short SP).That is to say, if OAM queue has OAM data, send at first the OAM data in OAM queue.In the time that OAM queue has not had data, then send other business datums according to original scheduling mode.
From above-mentioned process of transmitting, OAM always the very first time send, the simultaneously generation of Report frame also meets protocol requirement completely.
Embodiment tetra-
Fig. 8 is according to the flow chart of the OAM high priority data sending method of many LLID of the embodiment of the present invention.The same with the preferential dispensing device of single LLID, each LLID has a special OAM queue.Too, its specific implementation step and single LLID are similar for the scheduling mode of each OAM queue and single LLID, and as shown in Figure 8, this flow process comprises:
Step S802, reports to OLT by the Report frame of corresponding LLID.
Wherein, the size of OAM data embodies in highest-priority queue, can certainly be embodied in other service queues.
Step S804, OLT distributes time window.
The report value of the Report frame that OLT can send according to ONU, distributes to corresponding LLID time window.
Step S806, preferentially sends OAM data.
ONU gets after corresponding LLID window data, checks the queue situation of corresponding LLID.The same with the preferential sending method of single LLID, always first send OAM data.
Step S808, judges whether to exist next LLID.
If there is next LLID, perform step S802, otherwise process ends.
