主用单板接收到业务单板发送的业务信息后, 需要将业务信息发送给 其他业务单板和保护单板, 其中, 主用单板向业务单板和保护单板发送业 务信息的过程可以但不限于包含下述两种情况, 分别为:
第一种情况, 向业务单板和保护单板发送相同的业务信息, 具体的: 主用单板接收到某业务单板发送的业务信息后, 在其他业务单板中选择一 个处理该业务的业务单板, 然后将接收到的业务信息发送给选择出的业务 单板和保护单板, 例如, 如图 2所示, 业务单板 1 同时向主用单板和备用 单板发送业务 1的业务信息 1 , 主用单板和备用单板接收到业务信息 1后, 选择业务单板 2处理该业务, 将业务信息 1发送给业务单板 2和保护单板。
第二种情况, 向业务单板和保护单板发送不同的业务信息, 业务单板 接收第一业务对应的业务信息, 保护单板接收第二业务对应的业务信息, 具体的: 主用单板接收到某业务单板发送的业务信息后, 判断接收到的业 务信息是第一业务的业务信息还是第二业务的业务信息, 若为第一业务的 业务信息, 则在其他业务单板中选择一个处理该第一业务的业务单板, 然 后将接收到的业务信息发送给选择出的业务单板, 若为第二业务的业务信 息, 则将接收到的业务信息发送给保护单板, 其中, 第一业务可以但不限 于为主要业务, 第二业务可以但不限于为额外业务。 例如, 如图 3 所示, 业务单板 1同时向主用单板和备用单板发送业务 1的业务信息 1 ,业务单板 2同时向主用单板和备用单板发送业务 2的业务信息 2, 其中, 业务 1为主 要业务, 业务 2为额外业务, 主用单板和备用单板接收到业务信息 1后, 判断出该业务信息 1对应的业务 1为主要业务, 则在除业务单板 1之外的 其他业务单板中,选择出业务单板 3处理该业务 1 , 将业务信息 1发送给业 务单板 3; 主用单板和备用单板接收到业务信息 2后, 判断出该业务信息 2 对应的业务 1为额外业务, 则将业务信息 1发送给保护单板。
备用单板接收到业务单板发送的业务信息后, 需要将业务信息发送给 业务单板和保护单板, 与上述第一种情况(图 2所示)对应, 备用单板接 收到某业务单板发送的业务信息后, 在其他业务单板中选择一个处理该业 务的业务单板, 然后将接收到的业务信息发送给选择出的业务单板和保护 单板; 与上述第二种情况(图 3 所示)对应, 备用单板接收到某业务单板 发送的业务信息后, 判断接收到的业务信息是第一业务的业务信息还是第 二业务的业务信息, 若为第一业务的业务信息, 则在其他业务单板中选择 一个处理该第一业务的业务单板, 然后将接收到的业务信息发送给选择出 的业务单板, 若为第二业务的业务信息, 则将接收到的业务信息发送给保 护单板。
在本发明实施例中, 主用单板是当前处于主用工作状态的单板, 备用 单板是当前处于备用工作状态的单板, 若业务单板和保护单板分别进行主 用单板到备用单板的倒换, 即业务单板和保护单板分别将自身的接收业务 总线连接到备用单板, 主用单板倒换为备用单板, 备用单板倒换为主用单 板, 即倒换前的主用单板在倒换后变为备用单板, 倒换前的备用单板在倒 换后变为主用单板。
由于保护单板的接收业务总线连接到当前的主用单板, 因此保护单板 能够接收主用单板发送的业务信息。 保护单板可以和业务单板接收相同的 业务信息, 也可以接收不同的业务信息, 当业务单板和保护单板接收不同 的业务信息时, 保护单板还需要根据接收到的业务信息处理对应的业务。
基于图 1 所示的系统架构, 本发明实施例提出了一种单板倒换方法, 如图 4所示, 其具体处理流程如下:
步驟 41 , 保护单板获得当前的主用单板发送的业务信息。
其中, 当前的主用单板为当前处于主用工作状态的单板。
本发明实施例中, 业务单板和保护单板可能接收相同的业务信息, 主 用单板接收到某业务单板发送的业务信息后, 在其他业务单板中选择一个 处理该业务的业务单板, 然后将接收到的业务信息发送给选择出的业务单 板, 同时, 还需要将接收到的业务信息发送给保护单板; 此外, 业务单板和保护单板也可能接收不同的业务信息, 业务单板接 收第一业务的业务信息, 保护单板接收第二业务的业务信息, 主用单板接 收到某业务单板发送的业务信息后, 判断接收到的业务信息是第一业务的 业务信息还是第二业务的业务信息, 若为第一业务的业务信息, 则在其他 业务单板中选择一个处理该第一业务的业务单板, 然后将接收到的业务信 息发送给选择出的业务单板; 若为第二业务的业务信息, 则将接收到的业 务信息发送给保护单板。 其中, 第一业务可以但不限于为主要业务, 第二 业务可以但不限于为额外业务。
步驟 42 , 保护单板根据当前的主用单板发送的业务信息, 判断当前的 主用单板是否处于正常工作状态。
由于保护单板的接收业务总线此时连接到当前的主用单板, 因此保护 单板能够接收主用单板发送的业务信息。
保护单板根据当前的主用单板发送的业务信息, 判断当前的主用单板 是否处于正常工作状态可以但不限于由下述两种实施方式实现, 具体为: 第一种实施方式, 保护单板接收到当前的主用单板发送的业务信息后, 监测该业务信息对应的业务告警, 若监测到对应的业务告警, 则确认当前 的主用单板处于异常工作状态, 若未监测到对应的业务告警, 则确认当前 的主用单板处于正常工作状态, 业务告警可以由业务告警装置发出, 保护 单板判断业务告警装置发送的业务告警是否为该业务信息对应的业务告 警, 若是, 则确认监测到对应的业务告警;
第二种实施方式, 保护单板接收到当前的主用单板发送的业务信息之 后, 确定业务信息的各属性参数, 分别对各属性参数的参数值进行监测, 若监测到至少一个属性参数的属性值异常, 则确认当前的主用单板处于异 常工作状态, 若监测到所有属性参数对应的监测结果均正常, 则确认当前 的主用单板处于正常工作状态。 业务信息属性参数可以但不限于为下述参数中的一种或几种: 传输速 率、 信号峰值、 丟包率、 传输时延、 时延抖动。
其中, 分别对各属性参数的参数值进行监测时, 可以将属性参数的参 数值与该属性参数对应的规定阈值进行比较, 根据比较结果, 确定该属性 参数的属性值是否异常。 例如, 将传输速率的值与对应的规定阈值进行比 较, 若比较得到传输速率的值小于对应的规定阈值, 则可以认为传输速率 的值异常; 将丟包率的值与对应的规定阈值进行比较, 若比较得到丟包率 的值大于对应的规定阈值, 则可以认为丟包率的值异常。
若判断出当前的主用单板处于正常工作状态, 则保护单板继续接收当 前的主用单板发送的业务信息, 不进行主用单板到备用单板的倒换操作。
步驟 43 , 若步驟 42的判断结果为否, 则所述保护单板进行主用单板到 备用单板的倒换。
若保护单板根据当前的主用单板发送的业务信息判断出当前的主用单 板处于异常工作状态, 则保护单板进行主用单板到备用单板的倒换, 即保 护单板将自身的接收业务总线连接到当前的备用单板, 接收当前的备用单 板发送的业务信息, 此时, 各业务单板并未进行主用单板到备用单板的倒 换, 也就是说各业务单板的接收业务总线继续与当前的主用单板相连, 接 收当前的主用单板发送的业务信息。
步驟 44, 保护单板获得所述当前的备用单板发送的业务信息。
备用单板向保护单板发送的业务信息, 可以和备用单板向业务单板发 送的业务信息相同, 也可以不同, 例如, 备用单板将第一业务(主要业务) 的业务信息发送给业务单板, 将第二业务(额外业务) 的业务信息发送给 保护单板。
步驟 45 , 保护单板根据当前的备用单板发送的业务信息, 判断当前的 备用单板是否处于正常工作状态。 其中, 保护单板判断当前的备用单板是否处于正常工作状态的方法和 上述判断当前的主用单板是否处于正常工作状态的方法一致, 可以监测当 前的备用单板发送的业务信息对应的业务告警, 若监测到对应的业务告警, 则确认当前的备用单板处于异常工作状态, 若未监测到对应的业务告警, 则确认当前的备用单板处于正常工作状态; 还可以在接收到当前的备用单 板发送的业务信息之后, 获得业务信息的各属性参数, 对各属性参数的参 数值分别进行监测, 若监测到至少一个属性参数的参数值异常, 则确认当 前的备用单板处于异常工作状态, 若监测到所有属性参数的参数值均正常, 则确认当前的备用单板处于正常工作状态。
步驟 46, 若步驟 45的判断结果为是, 则所述保护单板控制各业务单板 分别进行主用单板到备用单板的倒换。
保护单板控制各业务单板分别进行主用单板到备用单板的倒换时, 可 以采用直接控制方式, 也可以采用间接控制方式, 其中:
直接控制方式为: 保护单板直接向各业务单板发送倒换控制信号, 各 业务单板接收到倒换控制信号后, 进行主用单板到备用单板的倒换, 即将 自身的接收业务总线连接到备用单板, 接收备用单板发送的业务信息; 间接控制方式为: 保护单板通过第三方倒换控制装置来控制各业务单 板进行主用单板到备用单板的倒换, 其中, 保护单板可以向第三方倒换控 制装置发送指示信息, 指示第三方倒换控制装置控制各业务单板进行主用 单板到备用单板的倒换, 第三方倒换控制装置接收到指示信息后, 向各业 务单板和保护单板发送倒换控制信号, 各业务单板接收到倒换控制信号后, 将自身的接收业务总线连接到备用单板上, 由于保护单板此时的接收业务 总线已经连接到备用单板上, 因此保护单板接收到倒换控制信号后无需执 行倒换操作; 此外, 保护单板也可以向第三方倒换控制装置发送主用单板 和备用单板的工作状态信息, 第三方倒换控制装置根据接收到的工作状态 信息来确认是否需要控制各业务单板进行主用单板到备用单板的倒换, 若 第三方倒换控制装置确定出主用单板处于异常工作状态, 而备用单板处于 正常工作状态, 则确认需要进行倒换, 第三方倒换控制装置向各业务单板 以及保护单板发送倒换控制信号, 各业务单板接收到倒换控制信号后, 将 自身的接收业务总线连接到备用单板上, 由于保护单板此时的接收业务总 线已经连接到备用单板上, 因此保护单板接收到倒换控制信号后无需执行 倒换操作。
各业务单板完成主用单板到备用单板的倒换后, 当前的主用单板变为 倒换前的备用单板, 当前的备用单板变为倒换前的主用单板。
若步驟 45的判断结果为否, 则保护单板进行备用单板到主用单板的倒 换, 将自身的接收业务总线连接到当前的主用单板上, 接收当前的主用单 板发送的业务信息。
由上述处理过程可知, 本发明实施例技术方案中, 保护单板若根据当 前的主用单板发送的业务信息, 判断出当前的主用单板处于异常工作状态, 则进行主用单板到备用单板的倒换, 保护单板若根据当前的备用单板发送 的业务信息, 判断出当前的备用单板处于正常工作状态, 则控制各业务单 板进行主用单板到备用单板的倒换。 由上可见, 本发明实施例技术方案中, 单板工作系统中的保护单板根据主用单板和备用单板的工作状态, 控制各 业务单板进行主用单板到备用单板的倒换, 因此单板工作系统能够在不增 加硬件设备的条件下, 自动进行单板倒换。
