Description

支持多种私有协议的ONU的管理方法及系统 技术领域
本发明涉及ONU(Optical Network Unit，光网络单元)配置领域，具体涉及一种支持多种私有协议的ONU的管理方法及系统。
背景技术
随着IPTV(交互式网络电视)、HDTV(High Definition Television，高清晰度电视)等视频业务的大量开展，在线游戏、互动等大流量宽带业务的普及，现有广泛应用的EPON带宽瓶颈日益明显。在此基础上，10GEPON(Ethernet Passive Optical Network，传输速率为10G/s的以太网无源光网络)技术的发展，很好的解决了现有的带宽不足问题，并且凭借对EPON的兼容性和平滑升级的优势，逐渐在带宽接入网领域崭露头角。
由于10G EPON优秀的向下兼容性，10G EPON的OLT(optical line terminal，光线路终端)设备需要同时支持10G EPON ONU、以及以前EPON设备下所有类型的1G EPON ONU。但是EPON初期1G EPON ONU很多都是以私有方式进行管理的，即每个ONU的私有方式不同，在此基础上，现有10G EPON的OLT管理不同私有方式的ONU时，会存在以下缺陷：
(1)现有的OLT不会存在所有1G EPON ONU的私有方式，因此只有OLT存在对应私有方式的ONU才能完成注册，若OLT上没有ONU的私有方式，该ONU则无法进行注册。
(2)因为不同ONU的业务传输队列不同，所以不同ONU传输 的业务、以及业务的传输速率上限均不同。因此，OLT针对不同ONU的处理机制都不相同，进而不仅导致OLT管理ONU时比较复杂，而且会增大ONU传输业务时发生故障的概率。
发明内容
针对现有技术中存在的缺陷，本发明解决的技术问题为：如何对支持多种私有协议的ONU进行管理。本发明显著降低了OLT的工作负荷、以及ONU传输业务时发生故障的概率。
为达到以上目的，本发明提供的支持多种私有协议的ONU的管理方法，包括以下步骤：
S1：OLT获取并添加所有需要管理的ONU的私有协议，转到S2；
S2：OLT通过ONU的私有协议，为所有ONU分配相同的业务传输队列，业务传输队列中设置有业务的传输速率上限，每条业务传输队列分配有对应的业务优先级，转到S3；
S3：OLT在ONU的业务传输队列中，选择与ONU支持的业务优先级对应的业务传输队列，进行业务传输。
在上述技术方案的基础上，S2的流程包括：
S201：OLT通过ONU的私有协议，获取ONU的业务传输队列，判断ONU的业务传输队列是否与需要分配的业务传输队列相同，若是，转到S202，否则向ONU发送需要分配的业务传输队列，重新执行S201；
S202：OLT清除ONU的每条业务传输队列的业务优先级后，为每条业务传输队列分配对应的业务优先级。
在上述技术方案的基础上，S201中ONU的业务传输队列与需要分配的业务传输队列相同的标准为：ONU的业务传输队列数量、以及每条业务传输队列传输速率上限，均与需要分配的业务传输队列相 同。
在上述技术方案的基础上，S2中所述业务传输队列的配置流程为：创建至少2条传输速率上限不同的上行业务传输队列、以及至少2条传输速率上限不同的下行业务传输队列；分别为每条上行业务传输队列和下行业务传输队列，分配对应的业务优先级。
在上述技术方案的基础上，S1的流程包括：OLT根据ONU的组织唯一标识符信息和私有信息，确定并添加ONU的私有协议。
本发明提供的支持多种私有协议的ONU的管理系统，包括设置于OLT上的私有协议添加模块、业务传输队列分配模块、以及业务传输队列绑定模块；
私有协议添加模块用于：获取并添加所有需要管理的ONU的私有协议，向业务传输队列分配模块发送业务传输队列分配信号；
业务传输队列分配模块用于：收到业务传输队列分配信号后，通过ONU的私有协议，为所有ONU分配相同的业务传输队列，业务传输队列中设置有业务的传输速率上限，每条业务传输队列分配有对应的业务优先级，向业务传输队列绑定模块发送业务传输队列绑定信号；
业务传输队列绑定模块用于：在ONU的业务传输队列中，选择与ONU支持的业务优先级对应的业务传输队列，进行业务传输。
在上述技术方案的基础上，所述业务传输队列分配模块的工作流程包括：通过ONU的私有协议获取ONU的业务传输队列，判断ONU的业务传输队列是否与需要分配的业务传输队列相同，若是，清除ONU的每条业务传输队列的业务优先级后，为每条业务传输队列分配对应的业务优先级；否则向ONU发送需要分配的业务传输队列后，重新开始工作。
在上述技术方案的基础上，所述业务传输队列分配模块判定ONU的业务传输队列与需要分配的业务传输队列相同的标准为：ONU的业务传输队列数量、以及每条业务传输队列传输速率上限，均与需要分配的业务传输队列相同。
在上述技术方案的基础上，所述业务传输队列分配模块还用于：配置业务传输队列，业务传输队列的配置流程为：创建至少2条传输速率上限不同的上行业务传输队列、以及至少2条传输速率上限不同的下行业务传输队列；分别为每条上行业务传输队列和下行业务传输队列，分配对应的业务优先级。
在上述技术方案的基础上，所述私有协议添加模块的工作流程包括：根据ONU的组织唯一标识符信息和私有信息，确定并添加ONU的私有协议。
与现有技术相比，本发明的优点在于：
(1)本发明对ONU进行注册时，能够在OLT上获取和添加ONU的私有协议，以此实现对不同私有协议的ONU进行注册；与此同时，本发明对ONU进行管理时，能够为所有ONU根据业务需要分配相同的业务传输队列(即每台ONU的业务传输队列的业务和传输速率上限相同)。因此，本发明能够使得OLT对不同私有协议的ONU进行统一管理，不仅简化了OLT管理ONU的过程，而且显著降低了ONU传输业务时发生故障的概率。
(2)本发明为ONU分配业务传输队列时，若ONU自身的业务传输队列与需要分配的业务传输队列相同时，则不为ONU重新分配业务传输队列，只为ONU重新划分业务传输队列中的业务优先级，进而降低了OLT的工作负荷。
附图说明
图1为本发明实施例中支持多种私有协议的ONU的管理方法的流程图。
具体实施方式
以下结合附图及实施例对本发明作进一步详细说明。
参见图1所示，本发明实施例中的支持多种私有协议的ONU的管理方法，包括以下步骤：
S1：OLT获取并添加所有需要管理的ONU的私有协议，转到S2。
S2：OLT通过ONU的私有协议，为所有ONU分配相同的业务传输队列，业务传输队列中设置有业务的传输速率上限，每条业务传输队列分配有对应的业务优先级(即对应优先级的业务通过相应的队列传输)，转到S3。
S3：OLT根据ONU的端口信息，确定ONU支持的业务；在ONU的业务传输队列中，选择与ONU支持的业务优先级对应的业务传输队列，进行业务传输。
下面通过五个实施对本发明的支持多种私有协议的ONU的管理方法进行说明。
实施例一：
S1的流程包括：OLT与ONU进行多点控制协议交互后，通过标准OAM协商，来采集ONU的远端OAM信息，获取远端OAM信息中ONU的组织唯一标识符信息；OLT与ONU进行扩展OAM协商后，采集扩展OAM协商的OAM版本号，根据OAM版本号获取ONU的私有信息，私有信息包括ONU的厂家信息、ONU的PON芯片信息和ONU的端口信息(根据ONU能力获取)；OLT根据ONU的组织唯一标识符信息和私有信息，确定并添加ONU的私有协议(即添加ONU的私有协议对应的私有OAM管理包)。
实施例二：
S2的流程包括：
S201：OLT通过ONU的私有协议，获取ONU自身的业务传输队列，判断ONU的业务传输队列是否与需要分配的业务传输队列相同，若是，转到S202，否则OLT对ONU进行复位(复位ONU的PON芯片)，待ONU重新上线后，向ONU发送需要分配的业务传输队列，重新执行S201。
S202：OLT清除ONU的每条业务传输队列的业务优先级后，为每条业务传输队列分配对应的业务优先级，S2结束，转到S3。
S2的原理为：当ONU自身的业务传输队列与需要分配的传输队列不同时，则需要重新为ONU分配业务传输队列及其传输速率上限。当ONU自身的业务传输队列与需要分配的业务传输队列相同时，则证明不需要重新为ONU分配业务传输队列，此时只需要为业务传输队列划分业务优先级，仅绑定业务优先级的工作负荷较低。因此，与无论ONU自身的业务传输队列如何，均为ONU重新分配业务传输队列相比，本发明在ONU自身的业务传输队列与需要分配的业务传输队列相同时，不为ONU重新分配业务传输队列，只为业务传输队列重新划分业务优先级，进而降低了OLT的工作负荷。
S201中ONU的业务传输队列与需要分配的业务传输队列相同的标准为：ONU的业务传输队列数量、每条业务传输队列传输速率上限，均与需要分配的业务传输队列相同。
实施例三：
S2中的业务传输队列可预先配置后直接分配，配置流程为：由于10G EPON主流使用单链路管理方式，因此本实施例将ONU设置为单链路管理方式，即将ONU的传输链路条目设置为1，这样可以 保持ONU的单链路统一管理。创建至少2条传输速率上限不同的上行业务传输队列、以及至少2条传输速率上限不同的下行业务传输队列。分别为每条上行业务传输队列和下行业务传输队列，分配对应的业务优先级。
实施例四：
在实施例三的基础上，S2中的上行业务传输队列为3条：传输速率上限的比例为1:1:5的上行业务传输队列1、2和3，下行业务传输队列也为3条：传输速率上限的比例为1:2:4的下行业务传输队列1、2和3。上行业务传输队列1和下行业务传输队列1的业务优先级为6和7、以及TDM(时分复用)业务(即基于TDM管理VLAN保护的业务默认入上行业务传输队列1和下行业务传输队列1)，上行业务传输队列2和下行业务传输队列2的业务优先级为4和5，上行业务传输队列3和下行业务传输队列3的业务优先级为0至3。
S3中选择与ONU支持的业务优先级对应的业务传输队列，进行业务传输的流程包括：将优先级为6和7的业务、以及TDM业务，通过上行业务传输队列1和下行业务传输队列1传输，将优先级为4和5的业务通过上行业务传输队列2和下行业务传输队列2传输，将优先级为0～3的业务通过上行业务传输队列3和下行业务传输队列3传输。
实施例五：
S3中OLT根据ONU的端口信息，确定ONU支持的业务的规则为：ONU支持数量大于0的端口对应的业务，例如：
如果POTS端口数量大于0，则支持VOIP业务；
如果E1端口数量大于0，则支持TDM业务；
如果WLAN端口数量大于0，则支持Wi-Fi业务；
如果ADSL端口数量大于0，则支持ADSL业务；
如果VDSL端口数量大于0，则支持VDSL业务；
如果CATV RF端口数量大于0，则支持CATV业务；
如果1PPS+TOD端口数量大于0，则支持基站接入业务。
实际执行S3时，还可以针对特殊业务直接指定业务传输队列，即可预留了一个配置特殊业务的逻辑链路规则的接口。
实施例六：
本发明实施例中的支持多种私有协议的ONU的管理系统，包括设置于OLT上的私有协议添加模块、业务传输队列分配模块、以及业务传输队列绑定模块。
私有协议添加模块用于：获取并添加所有需要管理的ONU的私有协议，向业务传输队列分配模块发送业务传输队列分配信号，具体流程为：根据ONU的组织唯一标识符信息和私有信息，确定并添加ONU的私有协议。
业务传输队列分配模块用于：收到业务传输队列分配信号后，通过ONU的私有协议，为所有ONU分配相同的业务传输队列，业务传输队列中设置有业务的传输速率上限，每条业务传输队列分配有对应的业务优先级，向业务传输队列绑定模块发送业务传输队列绑定信号。
业务传输队列分配模块的工作流程为：
(1)配置业务传输队列：创建至少2条传输速率上限不同的上行业务传输队列、以及至少2条传输速率上限不同的下行业务传输队列；分别为每条上行业务传输队列和下行业务传输队列，分配对应的业务优先级。
(2)通过ONU的私有协议获取ONU的业务传输队列，判断 ONU的业务传输队列是否与需要分配的业务传输队列相同(ONU的业务传输队列数量、以及每条业务传输队列传输速率上限，均与需要分配的业务传输队列相同)，若是，清除ONU的每条业务传输队列的业务优先级后，为每条业务传输队列分配对应的业务优先级；否则向ONU发送需要分配的业务传输队列后，重新开始工作。
业务传输队列绑定模块用于：在ONU的业务传输队列中，选择与ONU支持的业务优先级对应的业务传输队列，进行业务传输。
需要说明的是：本发明实施例提供的系统在进行模块间通信时，仅以上述各功能模块的划分进行举例说明，实际应用中，可以根据需要而将上述功能分配由不同的功能模块完成，即将系统的内部结构划分成不同的功能模块，以完成以上描述的全部或者部分功能。
进一步，本发明不局限于上述实施方式，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围之内。本说明书中未作详细描述的内容属于本领域专业技术人员公知的现有技术。
