Description

一种降低接入网设备的功耗方法及装置 技术领域
本发明涉及宽带接入网通信技术领域，尤其是DSL(Digital Subscriber Line，数字用户专线)、PON(Passive optical network，无源光纤网络)方面，更具体的说，涉及一种降低接入网设备功耗的方法及装置。
背景技术
接入网设备需要24小时不间断的开机运行，以提供用户不间断的上网服务，随着网络规模的不断扩大，运营商管理的设备消耗的能源也在日益增加，众所周知，随着我国经济的快速增长，对能源的消耗也越来越大，以往那种粗放型的增行方式，已经不可能支撑经济又好又快的发展，节能减排，既符合国家政策，同时也可以降低运营商日常维护的费用。
一台设备能耗的大小是和设备上用户端口的开通状态密切相关的，为了方便，运营商在初始配置时往往会把所有的用户端口都打开，这就存在着很大的浪费，因为实际上设备在运行过程中并不是所有的端口都开通了业务，如果能及时关闭设备上没有实际用户的端口，就能大幅的减少设备运行的能耗，达到节能减排的目标。
通常情况下，宽带运营商会维护一个放号资源库，以保存已经放号的用户信息，理论上可以根据放号资源库和现网设备上的端口进行比较来找出未使用的端口，在实际运维中运营商的放号资源库往往更新不及时，无法完全反映端口的实际业务开通情况，维护放号资源库，找出真正未使用的端口并一个个的加以关闭，对于运营商而言必须投入大量的人力资源，运维成本极高。

其中，所述的检测模块201包括：检测单元，设置成：在预置的时间周期内，通过采集所述接入网设备的各端口的输入输出字节数，检测所述接入网设备的各端口是否产生数据流量。
所述的判断模块202设置成按照如下方式根据对端口数据流量的监测结果，判断所述接入网设备是否存在未使用的端口：判断所述接入网设备的端口中是否存在不产生数据流量的端口，若存在不产生数据流量的端口，则判定该不产生数据流量的端口确定为未使用的端口，所述接入网设备存在未使用的端口；若不存在不产生数据流量的端口，则判定所述接入网设备不存在未使用的端口。
所述的关闭模块204包括：生成待关闭端口表单元，设置成：对所确定的未使用的通用端口进行统计，生成待关闭端口表；关闭单元，设置成：按照所生成的待关闭端口表，关闭所述接入网设备中未使用的通用端口。
本发明实施例中，所关闭的接入网设备中未使用的通用端口是处于开通状态的通用端口。
图3显示了本发明实施例提供的降低接入网设备功耗的结构图，如图3所示，包括网元端口数据采集模块301、放号资源库302、待关闭端口生成模块303以及自动关闭端口模块304。其中，所述网元端口数据采集模块301：负责采集网元设备的端口信息，记录端口的输入输出字节数，标记端口的使用状态。也就是说，所述网元端口数据采集模块301设置成：根据采样周期定期采集接入设备端口上的输入输出字节数，并和上一次采集到的结果进行比较，如果有变化则更新本次的采样时间点，并将该端口标记为使用状态；如果超过事先设置的时间周期端口上采集到的数据依然没有变化，则将该端口标记为未使用状态。所述放号资源库302：放号资源库由运营商维护，保存设备上的用户信息。也就是说，所述放号资源库302设置成：在放号资源库中有记录的端口是确定放号的，即使没有流量，也不允许关闭，所以在关闭端口前需要对运营商的放号资源库进行检索。待关闭端口生成模块303：根据网元端口数据采集模块采集到的端口使用状态、端口开通状态，再结合 放号资源库，生成待关闭端口表。也就是说，所述待关闭端口生成模块303设置成：从网元端口数据采集模块301提取端口的使用状态和开通状态，再结合放号资源库302，生成待关闭端口表，待关闭端口表可以以报表的方式提交运营商运维人员查看确认。自动关闭端口模块304：根据待关闭端口生成模块的结果关闭端口。也就是说，所述自动关闭端口模块304从待关闭端口生成模块303获取生成的待关闭端口表，根据表中的端口记录，自动将设备上的端口关闭，达到节能减排的目标。
本发明实施例只有当一个端口符合下述条件时，判定为待关闭端口：
1、端口标记为未使用状态；
2、端口处于开通状态；
3、端口在放号资源库302中检索不到。
其中，为防止误操作，所述自动关闭端口模块304在关闭端口时会详细记录操作日志，并支持回滚。
其中，PON组网场景下，接入设备是ONU(Optical Network Unit，光网络单元)；非PON组网场景，接入设备是DSLAM(Digital Subscriber Line Access Multiplexer，数字用户线路接入复用器)和MSAN(Multi-Service Access Network，综合业务接入网)。
图4显示了本发明实施例提供的一种自动化关闭未使用端口降低功耗的方法，通过检测接入设备用户端口上是否存在流量来定位端口使用情况。当一个用户端口被使用时，在该端口上必然会产生流量，从而改变端口上的输入输出字节数，因此，通过判断前后两次采集时端口上的输入输出字节数是否发生变化即可以判断出一个端口是否有过流量。该方法包括以下步骤：
步骤S401：定期采集设备上所有端口的输入输出字节数。
采集网元设备的端口信息，并记录端口的输入输出字节数。
步骤S402：端口超过设定的时间后输入输出字节数没有改变，标记为未使用。
根据采样周期定期采集接入设备端口上的输入输出字节数，并和上一次采集到的结果进行比较，如果有变化则更新本次的采样时间点，并将该端口标记为使用状态；如果超过事先设置的时间周期端口上采集到的数据依然没 有变化，则将该端口标记为未使用状态。
步骤S403：检索运营商放号资源库，不在资源库检索结果中的未使用端口标记为待关闭。
在放号资源库中有记录的端口是确定放号的，即使没有流量，也不允许关闭，所以在关闭端口前需要对运营商的放号资源库进行检索。
步骤S404：自动关闭待关闭的端口。
关闭待关闭的端口，并在所述待关闭端口关闭后，关闭端口需要记录日志，并支持回滚。
从网元端口数据采集模块301提取端口的使用状态和开通状态，再结合放号资源库302，生成待关闭端口表，根据待关闭端口表中的端口记录，自动将设备上的端口关闭。
本发明实施例提供的一种计算机程序，包括程序指令，当该程序指令被终端执行时，使得该终端可执行上述图4所示的任意的自动化关闭未使用端口降低功耗的方法。
本发明实施例提供的一种载有上述任意的计算机程序的载体。
综上所述，本发明实施例具有以下技术效果：
本发明实施例通过对接入设备端口数据进行分析进而定位并关闭未使用的用户端口，判断端口未使用状态准确率高，减少设备能耗且无需人工干预，运维成本低。
尽管上文对本发明进行了详细说明，但是本发明不限于此，本技术领域技术人员可以根据本发明的原理进行各种修改。因此，凡按照本发明原理所作的修改，都应当理解为落入本发明的保护范围。
工业实用性
上述技术方案能自动定位接入设备中未被使用的端口，生成待关闭端口列表并及时关闭，从而降低设备能耗，降低运营商的运行维护费用，同时满足节能减排的目标。因此本发明具有很强的工业实用性。
