Description

一种数据处理方法及装置、数据控制单元、存储介质Data processing method and device, data control unit and storage medium 技术领域Technical field
本发明涉及光网络单元(Optical Network Unit,ONU)内部的数据处理技术,尤其涉及一种ONU数据处理方法及装置、数据控制单元、存储介质。The present invention relates to data processing technologies within an Optical Network Unit (ONU), and more particularly to an ONU data processing method and apparatus, a data control unit, and a storage medium.
背景技术Background technique
以太网无源光网络(Ethernet Passive Optical Network,EPON)技术将每个ONU扩展到八路逻辑链路标记(Logical Link Identifier,LLID),八路LLID的设计可以大幅度增加应用层业务数据的类型,从而支持更多种类的应用服务。同样,在吉比特无源光网络(Gigabit-Capable PON,GPON)系统中,一般是支持32至64个传输容器(TCONT),从而可支持更多种类的业务。The Ethernet Passive Optical Network (EPON) technology extends each ONU to an eight-way Logical Link Identifier (LLID). The design of the eight-way LLID can greatly increase the type of application layer service data. Support for a wider variety of application services. Similarly, in Gigabit-Capable PON (GPON) systems, 32 to 64 transport containers (TCONT) are typically supported to support a wider variety of services.
流量管理(Traffic Management,TM)上行出口数据控制单元是ONU的重要组成部分,在支持多LLID/TCONT的系统下,当出现随机拔掉的光纤又再次被插上时,ONU需要重新注册;当重新注册的LLID号或TCONT号与原来一致时,TM上行出口数据控制单元可以按照硬件逻辑进行数据处理,将正确的数据发送给介质访问控制(Medium Access Control,MAC)单元;但当重新注册的LLID号或TCONT号与原来不一致时,如果TM上行出口数据控制单元仍然按照硬件逻辑进行数据处理,就无法清除已缓存的数据,也无法保证数据处理的正确性。Traffic Management (TM) uplink egress data control unit is an important part of ONU. Under the system supporting multiple LLID/TCONT, when the randomly unplugged fiber is plugged in again, the ONU needs to be re-registered; When the re-registered LLID number or TCONT number is consistent with the original, the TM uplink egress data control unit can perform data processing according to the hardware logic, and send the correct data to the Medium Access Control (MAC) unit; but when re-registered If the LLID number or TCONT number is inconsistent with the original, if the TM uplink export data control unit still performs data processing according to the hardware logic, the cached data cannot be cleared, and the correctness of data processing cannot be guaranteed.

Discard directly.
为了使本发明实施例的目的、技术方案和优点更加清楚,下面结合附图对本发明实施例作进一步的详细描述。The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.
图1为本发明实施例ONU数据处理方法的实现流程示意图,如图1所示,本发明实施例ONU数据处理方法包括以下步骤:FIG. 1 is a schematic flowchart of an ONU data processing method according to an embodiment of the present invention. As shown in FIG. 1 , an ONU data processing method according to an embodiment of the present invention includes the following steps:
步骤101,接收未分配带宽的流量承载实体号;Step 101: Receive a traffic bearer entity number of an unallocated bandwidth.
步骤102:对与所述未分配带宽的流量承载实体号对应的数据进行清除处理;Step 102: Perform a clearing process on data corresponding to the traffic bearer entity number of the unallocated bandwidth.
本步骤可由ONU中的TM上行出口数据控制单元完成;所述未分配带宽的流量承载实体号来自ONU中的CPU;其中,所述流量承载实体号可以是TCONT号,也可以是LLID号。This step can be performed by the TM uplink egress data control unit in the ONU; the unloaded bandwidth traffic bearer entity number is from the CPU in the ONU; wherein the traffic bearer entity number can be a TCONT number or an LLID number.
这里,所述对与所述未分配带宽的流量承载实体号对应的数据进行清除处理包括:读取TM上行出口数据控制单元中与所述未分配带宽的流量承载实体号对应的数据进行丢弃;读取TM上行出口数据控制单元中与所 述未分配带宽的流量承载实体号对应的描述符进行丢弃,并将数据缓存单元中与所述描述符对应的数据包进行丢弃。Here, the performing the clearing process on the data corresponding to the traffic bearer entity number of the unallocated bandwidth includes: reading data corresponding to the traffic bearer entity number of the unallocated bandwidth in the TM uplink egress data control unit, and discarding; Read TM upstream export data control unit The descriptor corresponding to the traffic bearer entity number of the unallocated bandwidth is discarded, and the data packet corresponding to the descriptor in the data buffer unit is discarded.
需要说明的是,在所述TM上行出口数据控制单元接收CPU发送的未分配带宽的流量承载实体号之前,该方法还包括:CPU实时监控流量承载实体号,将未分配带宽的流量承载实体号发送给所述TM上行出口数据控制单元。It is to be noted that before the TM uplink egress data control unit receives the traffic bearer entity number of the unallocated bandwidth sent by the CPU, the method further includes: the CPU monitoring the traffic bearer entity number in real time, and the traffic bearer entity number of the unallocated bandwidth Send to the TM uplink export data control unit.
例如,如果流量承载实体号是TCONT号,CPU会对当前的TCONT号进行监控,判断哪些TCONT号有效的,哪些TCONT号被废弃的,具体的,在拔插光纤之后,CPU监控重新注册的TCONT号与原TCONT号是否一致,从而判断哪些TCONT号是有效的,哪些TCONT号是被废弃的,也就是说,如果重新注册后的TCONT号与原TCONT号不一致时,当前使用的是新注册的TCONT号,而原TCONT号不再被分配带宽,那未被分配带宽的TCONT号就是被废弃的。CPU就将未分配带宽的TCONT号发送给TM上行出口数据控制单元;For example, if the traffic bearer entity number is TCONT, the CPU monitors the current TCONT number to determine which TCONT numbers are valid and which TCONT numbers are discarded. Specifically, after the fiber is removed, the CPU monitors the re-registered TCONT. Whether the number is the same as the original TCONT number, so as to determine which TCONT numbers are valid and which TCONT numbers are discarded, that is, if the TCONT number after re-registration is inconsistent with the original TCONT number, the new registration is currently used. The TCONT number, while the original TCONT number is no longer allocated bandwidth, the TCONT number of the unallocated bandwidth is discarded. The CPU sends the TCONT number of the unallocated bandwidth to the TM uplink export data control unit;
相应的,TM上行出口数据控制单元接收未分配带宽的TCONT号,TM上行出口数据控制单元中具有TCONT数据存储空间和TCONT描述符存储空间;在接收到未分配带宽的TCONT号之后,读取存储在TCONT数据存储空间中的与未分配带宽的TCONT号对应的数据并进行丢弃,读取存储在TCONT描述符存储空间中的与未分配带宽的TCONT号对应的描述符并进行丢弃;并且,将存储在数据缓存单元中的与上述描述符对应的数据包也进行丢弃。Correspondingly, the TM uplink egress data control unit receives the TCONT number of the unallocated bandwidth, and the TM uplink egress data control unit has the TCONT data storage space and the TCONT descriptor storage space; after receiving the TCONT number of the unallocated bandwidth, the read storage Data corresponding to the TCONT number of the unallocated bandwidth in the TCONT data storage space is discarded, and the descriptor corresponding to the TCONT number of the unallocated bandwidth stored in the TCONT descriptor storage space is read and discarded; and, The data packets corresponding to the above descriptors stored in the data buffer unit are also discarded.
步骤103,判断是否有带宽,没有带宽时,对与所述未分配带宽的流量承载实体号对应的数据包标记错误信息,并丢弃标记错误信息的数据包;Step 103: Determine whether there is bandwidth, and if there is no bandwidth, mark the error packet with the data packet corresponding to the traffic bearer entity number of the unallocated bandwidth, and discard the data packet marked with the error information;
本步骤的判断、标记以及丢弃操作可以由MAC单元完成;The judgment, marking and discarding operations of this step can be completed by the MAC unit;
这里,所述方法还包括:有带宽时,发送与所述未分配带宽的流量承 载实体号对应的数据包;其中,所述发送数据包操作可由MAC单元完成。Here, the method further includes: when there is bandwidth, transmitting the traffic with the unallocated bandwidth The data packet corresponding to the entity number; wherein the sending data packet operation can be completed by the MAC unit.
在实际应用中,数据传输过程中如果光纤被拔下,有可能出现部分数据包已到达MAC单元的情况,MAC单元接收TM上行出口数据控制单元发送的未分配带宽的TCONT号,对于已到达MAC单元的与未分配带宽的TCONT号对应的数据包,MAC单元会根据自身的情况进行处理;具体的,MAC单元具有统计带宽使用情况的寄存器,根据寄存器中存储的数据去判断是否仍有带宽;当有带宽时,则将与未分配带宽的TCONT号对应的数据包继续发送出去,当没有带宽时,则先对与未分配带宽的TCONT号对应的数据包标记错误信息,然后再进行丢弃。In practical applications, if the optical fiber is unplugged during data transmission, it may happen that part of the data packet has arrived at the MAC unit, and the MAC unit receives the TCONT number of the unallocated bandwidth sent by the TM uplink egress data control unit, for the MAC that has arrived. The data packet corresponding to the TCONT number of the unallocated bandwidth of the unit, the MAC unit will process according to its own situation; specifically, the MAC unit has a register for statistical bandwidth usage, and judges whether there is still bandwidth according to the data stored in the register; When there is bandwidth, the data packet corresponding to the TCONT number of the unallocated bandwidth is continuously transmitted. When there is no bandwidth, the data packet corresponding to the TCONT number of the unallocated bandwidth is first marked with an error message, and then discarded.
本发明实施例还提出一种计算机可读存储介质,该存储介质包括一组指令,所述指令用于执行如图1所示的方法。Embodiments of the present invention also provide a computer readable storage medium including a set of instructions for performing the method as shown in FIG.
图2为本发明实施例ONU数据处理装置的组成结构示意图,如图2所示,所述ONU数据处理装置包括:数据缓存单元201、TM上行出口数据控制单元202、MAC单元203以及CPU 204;其中,2 is a schematic structural diagram of an ONU data processing apparatus according to an embodiment of the present invention. As shown in FIG. 2, the ONU data processing apparatus includes: a data buffer unit 201, a TM uplink egress data control unit 202, a MAC unit 203, and a CPU 204; among them,
数据缓存单元201,配置为为TM缓存数据;The data cache unit 201 is configured to cache data for the TM;
TM上行出口数据控制单元202,配置为接收CPU 204发送的未分配带宽的流量承载实体号,对与所述未分配带宽的流量承载实体号对应的数据进行清除处理,并将所述未分配带宽的流量承载实体号发送给MAC单元203;The TM uplink egress data control unit 202 is configured to receive the traffic bearer entity number of the unallocated bandwidth sent by the CPU 204, perform clear processing on the data corresponding to the traffic bearer entity number of the unallocated bandwidth, and clear the unallocated bandwidth. The traffic bearer entity number is sent to the MAC unit 203;
MAC单元203,配置为判断是否有带宽,当没有带宽时,对与所述未分配带宽的流量承载实体号对应的数据包标记错误信息,并丢弃标记错误信息的数据包;The MAC unit 203 is configured to determine whether there is bandwidth. When there is no bandwidth, the data packet corresponding to the traffic bearer entity number of the unallocated bandwidth is marked with an error message, and the data packet marked with the error information is discarded;
这里,所述MAC单元203根据自身具有统计带宽使用情况功能的寄存器中存储的数据可以自行判断是否仍有带宽;Here, the MAC unit 203 can determine whether there is still bandwidth according to data stored in a register having a function of counting bandwidth usage.
CPU 204,配置为将未分配带宽的流量承载实体号发送给TM上行出口 数据控制单元202。The CPU 204 is configured to send the traffic bearer entity number of the unallocated bandwidth to the TM uplink exit Data control unit 202.
进一步地,所述MAC单元203,还配置为当有带宽时,发送与所述未分配带宽的流量承载实体号对应的数据包。Further, the MAC unit 203 is further configured to: when there is bandwidth, send a data packet corresponding to the traffic bearer entity number of the unallocated bandwidth.
在实际应用中,假设流量承载实体号是TCONT号,在出现随机拔掉的光纤又再次被插上时,CPU 204监控重新注册的TCONT号与原TCONT号是否一致,从而判断哪些TCONT号是有效的,哪些TCONT号是被废弃的,也就是说,如果重新注册的TCONT号与原来不一致,当前使用的是新注册的TCONT号,而原TCONT号不再被分配带宽,那未被分配带宽的TCONT号就是被废弃的,那么,CPU 204就对所有的TCONT号进行监控,得到未分配带宽的TCONT号发送给TM上行出口数据控制单元202;TM上行出口数据控制单元202中具有TCONT数据存储空间和TCONT描述符存储空间;在接收未分配带宽的TCONT号之后,读取出存储在TCONT数据存储空间中的与未分配带宽的TCONT号对应的数据并进行丢弃,读取出存储在TCONT描述符存储空间中的与未分配带宽的TCONT号对应的描述符并进行丢弃;且将存储在数据缓存单元201中与上述描述符对应的数据包也进行丢弃。In practical applications, it is assumed that the traffic bearer entity number is the TCONT number. When the randomly unplugged fiber is plugged in again, the CPU 204 monitors whether the re-registered TCONT number is consistent with the original TCONT number, thereby determining which TCONT numbers are valid. Which TCONT numbers are discarded, that is, if the re-registered TCONT number is inconsistent with the original, the newly registered TCONT number is currently used, and the original TCONT number is no longer allocated bandwidth, and the bandwidth is not allocated. The TCONT number is discarded. Then, the CPU 204 monitors all the TCONT numbers, and obtains the TCONT number of the unallocated bandwidth and sends it to the TM uplink egress data control unit 202. The TM uplink egress data control unit 202 has the TCONT data storage space. And the TCONT descriptor storage space; after receiving the TCONT number of the unallocated bandwidth, the data corresponding to the TCONT number of the unallocated bandwidth stored in the TCONT data storage space is read and discarded, and the TCONT descriptor is read and stored. a descriptor corresponding to the TCONT number of the unallocated bandwidth in the storage space and discarded; and will be stored in the data cache unit 201 and Corresponding packet descriptor also discarded.
同时,TM上行出口数据控制单元202还会将未分配带宽的TCONT号发送给MAC单元203,对于MAC单元203已经接收到的与未分配带宽的TCONT号对应的数据包,MAC单元203会根据自身的情况进行处理;具体的,MAC单元203具有统计带宽使用情况功能的寄存器,MAC单元203可以根据自身寄存器中存储的数据去判断是否仍有带宽;具体寄存器中存储的统计带宽使用情况,MAC单元203可以基于自身内部的时钟实时更新。当有带宽时,则将与未分配带宽的TCONT号对应的数据包继续发送出去;当没有带宽时,则对与未分配带宽的TCONT号对应的数据包进行标记,标记上错误信息,并丢弃标记错误信息的数据包;进而使得ONU在出现随机 拔掉的光纤又再次被插上时,CPU204监控重新注册的LLID号或TCONT号与原LLID号或TCONT号是否一致,如果重新注册的LLID号或TCONT号与原来不一致,能够清除滞留在其内部的残余数据,保证了ONU数据处理的正确性。At the same time, the TM uplink egress data control unit 202 also transmits the TCONT number of the unallocated bandwidth to the MAC unit 203. For the data packet corresponding to the TCONT number of the unallocated bandwidth that the MAC unit 203 has received, the MAC unit 203 will according to itself. The case is processed; specifically, the MAC unit 203 has a register for counting the bandwidth usage function, and the MAC unit 203 can determine whether there is still bandwidth according to the data stored in the own register; the statistical bandwidth usage stored in the specific register, the MAC unit The 203 can be updated in real time based on its own internal clock. When there is bandwidth, the data packet corresponding to the TCONT number of the unallocated bandwidth is continuously sent out; when there is no bandwidth, the data packet corresponding to the TCONT number of the unallocated bandwidth is marked, the error information is marked, and the error is discarded. Marking the packet of the error message; thus causing the ONU to appear randomly When the unplugged fiber is plugged in again, the CPU 204 monitors whether the re-registered LLID number or TCONT number is consistent with the original LLID number or TCONT number. If the re-registered LLID number or TCONT number is inconsistent with the original, it can clear the stay in the internal The residual data ensures the correctness of the ONU data processing.
