Description

跨版本升级方法、装置及设备、计算机可读存储介质 技术领域
本公开涉及通信技术领域。
背景技术
在现有的网络中，考虑到组网成本和维护成本，承载网设备可能不部署双归保护。由于没有备用节点保护，对于核心节点处的设备的版本升级来说，如果业务中断，影响将非常大。在进行版本升级过程中会因为设备被整机复位导致业务中断，中断的时间需要等待版本升级完成之后才结束。在核心节点上，业务配置量一般非常大，设备的版本升级以及业务配置完成时间会非常长，从而导致版本升级过程中设备重启导致业务中断时间非常长。
发明内容

本公开的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
为了使本公开所要解决的技术问题、技术方案及有益效果更加清楚、明白，以下结合附图和实施例，对本公开进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。
针对版本升级导致业务中断时间过长的问题，可采用软复位技术，即，转发芯片不复位，只是软件复位版本升级。由于转发芯片没有复位，从而业务还是能保证不中断。但是软复位技术存在的问题是，只能升级软件版本，不能升级硬件芯片对应的版本，例如FPGA(现场可编程门阵列)版本以及微码版本。
有鉴于此，根据本公开的实施例在于提供一种跨版本升级方法、跨版本升级装置、跨版本升级设备、计算机可读存储介质，以解决承载网设备在跨版本升级过程中，在没有部署双归保护的情况下，复位设备导致业务长时间中断的问题。
图1为根据本公开的实施例的跨版本升级方法的流程示意图。
如图1所示，根据本公开的实施例的跨版本升级方法包括步骤S11至步骤S14。
在步骤S11，复位升级设备的备用主控板。
根据本公开的实施例，所述设备包括但不限于为PTN(分组传送网)、POTN(分组光传送网络)、OTN(光传送网络)、路由器等数据或承载设备。
在步骤S12，对所述设备的主用主控板和复位升级后的备用主控板进行同步，并在同步完成后，对所述主用主控板和复位升级后的备用主控板进行主备倒换。
根据本公开的实施例，所述主备倒换即为将主用主控板切换为备用主控板，将备用主控板切换为主用主控板。也就是说，在步骤S12完成后，复位升级后的备用主控板被切换为主用主控板，进行主备倒换前的主用主控板被切换为备用主控板。
在步骤S13，在主备倒换完成后，复位升级切换后的备用主控板，即，复位升级进行主备倒换前的所述设备的主用主控板。从而使得在步骤S13完成后，主用主控板和备用主控板均得到复位升级。
在步骤S14，根据业务的保护关系复位升级线卡单板。
图2为根据本发明公开的第一实施例的跨版本升级方法的另一流程示意图。如图2所示，根据本发明的实施例的跨版本升级方法包括步骤S10至步骤S14。图2中的步骤S 11至S14与参照图1所描述的步骤S11至S14基本相同，在此将不再进行重复描述。与参照图1所描述的跨版本升级方法不同的是，图2的跨版本升级方法还包括在步骤S11之前的步骤S10。
在步骤S10，对复位升级前的主用主控板和备用主控板进行同步。
根据本公开的实施例，通过对复位升级前的主用主控板和备用 主控板进行同步，使得复位升级前的主用主控板和备用主控板上的配置数据保持一致，便于后续主用主控板和备用主控板的复位升级。
下面将详细描述图1和图2中的步骤S 14。
根据本公开的实施例，所述保护关系表示与同一业务的特定方向对应的线卡单板不在同一个复位升级批次中。
根据本公开的实施例，所述根据所述保护关系复位升级所述线卡单板包括以下步骤：根据所述保护关系确定所述线卡单板的复位升级批次；按照所述线卡单板的复位升级批次，复位升级所述线卡单板。
根据本公开的实施例，所述根据所述保护关系确定所述线卡单板的复位升级批次包括以下步骤：将所有线卡单板初始化到第一预设池中；根据所述设备的所有业务的配置，依次确定每条业务入向方向的线卡单板和每条业务出向方向的线卡单板；针对每条业务，在入向方向的线卡单板符合所述保护关系的情况下，将符合所述保护关系的线卡单板确定为第一复位升级批次；针对每条业务，在出向方向的线卡单板符合所述保护关系的情况下，将符合所述保护关系的线卡单板确定为所述第一复位升级批次。
根据本公开的实施例，所述根据所述保护关系确定所述线卡单板的复位升级批次还包括以下步骤：在所有业务中的一条业务入向方向的线卡单板不符合所述保护关系的情况下，将该条业务入向方向的线卡单板中的一个线卡单板放入到第二预设池中；在所有业务中的一条业务出向方向的线卡单板不符合所述保护关系的情况下，将该条业务出向方向的线卡单板中的一个线卡单板放入到所述第二预设池中；将所述第二预设池中的线卡单板确定为第二复位升级批次。
具体地，在将所有线卡单板初始化到第一预设池中之后，确定每条业务入向方向的线卡单板和每条业务出向方向的线卡单板，可依次判断每条业务入向方向的线卡单板是否符合所述保护关系，若某条业务入向方向的线卡单板不符合所述保护关系，则将该条业务入向方向的线卡单板中的一个线卡单板放入到所述第二预设池中，若该条业务入向方向的线卡单板符合所述保护关系，则处理下一条业务入向方向的线卡单板，直至所有业务入向方向的线卡单板都被判断完成为止。 在所有业务入向方向的线卡单板都被判断完成之后，判断每条业务出向方向的线卡单板是否符合所述保护关系，若某条业务出向方向的线卡单板不符合所述保护关系，则将该条业务出向方向的线卡单板中的一个线卡单板放入到所述第二预设池中，若该条业务出向方向的线卡单板符合所述保护关系，则处理下一条业务出向方向的线卡单板，直至所有业务出向方向的线卡单板都被判断完成为止。
需要说明的是，所述将该条业务入向方向中的线卡单板中的一个线卡单板放入到所述第二预设池中包括以下步骤：将该条业务入向方向中的线卡单板中的一个线卡单板放入到所述第二预设池中，判断该线卡单板是否影响到与第二预设池中相应的业务，即判断该线卡单板使得第二预设池中的一条业务入向方向的线卡单板不符合所述保护关系，若该线卡单板放入到所述第二预设池中影响到第二预设池中的一条业务，则需要将该线卡单板放入到第三预设池，再判断该线卡单板放入到所述第三预设池中是否影响到与所述第三预设池中的相应的业务，依次类推。
所述将该条业务出向方向中的线卡单板中的一个线卡放入到其他预设池中，与上述类似，在此不作赘述。
根据本公开的实施例，通过保护关系计算出所述设备的线卡单板的复位升级批次，即为业务最小的复位升级批次，从而可以减少复位升级的时间。
根据本公开的实施例，在复位升级线卡单板时，由于业务存在保护关系，工作业务和保护业务不会配置在同一块线卡单板上，防止单板故障的时候工作和保护都失效，即，与一个业务对应的线卡单板包括工作线卡单板和保护线卡单板。复位升级一块线卡单板时，业务会倒换到另外一块线卡单板上，业务的倒换时间是可以通过现有的快速倒换功能来保证倒换时间在电信级倒换时间内。在复位升级的那块单板升级成功之后，再复位升级另外一块单板。也就是只要工作线卡单板和保护线卡单板分布在不同的复位升级批次中，则能满足业务不中断的要求，只会出现业务倒换时的瞬断，能够满足电信级的要求。
由于业务存在入向和出向，在入向和出向上会分别配置保护。 在入向上存在工作线卡单板和保护线卡单板，在出向上也存在工作线卡单板和保护线卡单板。入向的线卡单板和出向的线卡单板是不存在依赖关系的，可以将入向的线卡单板和出向的线卡单板统一考虑复位升级批次。只需要将某一方向的工作线卡单板和保护线卡单板分开即可，也就是同一业务在某一方向的工作线卡单板和保护线卡单板不在同一个复位升级批次中。
再考虑可能存在保护叠加的问题，例如业务出向存在两层保护组叠加，那么它将有多块板可以出去，只要分配的这几块单板不在同一个复位升级批次即可。
为了更好地阐述本实施例，以下结合图5、以及图6-图9对跨版本升级过程进行详细地说明。
如图5所示，为工程中一种典型的2G单归业务组网结构示意图。该组网图中的A网元即为核心节点，对于A网元设备进行复位升级的时候，就会导致业务长时间的中断。
A网元设备在业务的用户侧配置了MSP(复用段保护)保护组，在网络侧配置了LSP(标签交换通道)保护组。与MSP保护组对应的线卡单板为线卡单板1和线卡单板2，工作业务在线卡单板1上，保护业务在线卡单板2上。与LSP保护组对应的线卡单板为线卡单板3和线卡单板4，工作业务在线卡单板3上，保护业务在线卡单板4上。下面将参照图6至图9详细描述对A网元设备进行不中断业务升级的过程。
假设A网元设备的主控板存在1+1保护，同时已经同步完成，主用主控板和备用主控板上的配置数据一模一样。
如图6所示，首先复位备用主控板，并将复位后的备用主控板升级到最新版本(图6至图9中的虚线框表示已经升级到最新版本)。对原主用主控板与升级之后的备用主控板进行数据同步，在同步完成之后，对所述主用主控板和所述备用主控板进行主备倒换，即，将升级之后的备用主控板切换为主用主控板，将原主用主控板切换为备用主控板。
如图7所示，在主备倒换完成之后，复位切换后的备用主控板 (即，原主用主控板)，并将复位后的备用主控板(即，原主用主控板)升级到最新版本，从而完成对原主用主控板和原备用主控板的升级。
在复位升级线卡单板时，首先根据业务的保护关系，计算线卡单板的复位升级批次。
先将线卡单板1、线卡单板2、线卡单板3和线卡单板4放入到池1中，然后开始遍历A网元上的业务配置。从左往右的业务方向上看，入向是MSP保护组，出向是LSP保护组。判断业务的入向是否满足复位升级要求，由于线卡单板1和线卡单板2都在同一个池中，所以不满足，将线卡单板1放入到池2中。判断业务的出向是否满足复位升级要求，由于线卡单板3和线卡单板4都在同一个池中，所以不满足，将线卡单板3放入到池2中。通过上述方式，可以确定两个复位升级批次，即线卡单板2和线卡单板4、线卡单板1和线卡单板3。
如图8和图9所示，首先复位升级第一批次，即线卡单板2和线卡单板4；然后再复位升级第二批次，即线卡单板1和线卡单板3。由于业务存在保护关系，在复位升级线卡单板时，业务会倒换到另外一块线卡单板上，例如：在复位升级线卡单板2时，业务会倒换到线卡单板1上；复位升级线卡单板4时，业务会倒换到线卡单板3上。因此能满足业务不中断的要求，只会出现业务倒换时的瞬断，能够满足电信级的要求。
由于业务是双向的，从另外一个方向上看，根据前述确定的复位升级批次已经能够满足从右往左的业务升级要求。
遍历其他业务，由于本网元的业务配置都是用户侧配置MSP保护组，工作业务在线卡单板1上，保护业务在线卡单板2上；网络侧配置的是LSP保护组，工作业务在线卡单板3上，保护业务在线卡单板4上，根据前述确定的复位升级批次已经能够满足要求。
根据本公开的实施例的跨版本升级方法，通过设备主控板的主备保护以及线卡板业务之间的保护关系，进行复位升级；解决了承载网设备在跨版本升级过程中，在没有部署双归保护的情况下，复位设备导致业务长时间中断的问题；在跨版本升级过程中，只有业务倒换 过程的少许丢包，能够满足电信级的要求。
图3为根据本公开的实施例的跨版本升级装置的结构示意图。
如图3所示，根据本公开的实施例的跨版本升级装置包括第一复位升级模块21、主备倒换模块22、第二复位升级模块23以及第三复位升级模块24。
所述第一复位升级模块21，用于复位升级设备的备用主控板。
根据本公开的实施例，所述设备包括但不限于为PTN、POTN、OTN、路由器等数据或承载设备。
根据本公开的实施例，所述装置还可包括同步模块(附图未示出)，所述同步模块，用于在第一复位升级模块21复位升级设备前，将主用主控板和备用主控板进行同步。
根据本公开的实施例，通过对复位升级前的主用主控板和备用主控板进行同步，使得复位升级前的主用主控板和备用主控板上的配置数据保持一致，便于后续主用主控板和备用主控板的复位升级。
所述主备倒换模块22，用于对所述设备的主用主控板和复位升级后的备用主控板进行同步，并在同步完成的情况下，对所述主用主控板和所述备用主控板进行主备倒换。
根据本公开的实施例，所述主备倒换即为将主用主控板切换为备用主控板，将备用主控板切换为主用主控板。也就是说，在主备倒换完成后，复位升级后的备用主控板被切换为主用主控板，进行主备倒换前的主用主控板被切换为备用主控板。
所述第二复位升级模块23，用于在主备倒换成功的情况下，复位升级切换后的备用主控板，即，复位升级进行主备倒换前的所述设备的主用主控板。从而使得，主用主控板和备用主控板均得到复位升级。
所述第三复位升级模块24，用于根据业务的保护关系复位升级所述线卡单板。已经参照图1和图2的步骤S14详细描述了根据所述保护关系复位升级所述线卡单板的详细过程，再次将不再进行重复描述。
根据本公开的实施例的跨版本升级装置，通过设备主控板的主 备保护以及线卡板业务之间的保护关系，进行复位升级；解决了承载网设备在跨版本升级过程中，在没有部署双归保护的情况下，复位设备导致业务长时间中断的问题；在跨版本升级过程中，只有业务倒换过程的少许丢包，能够满足电信级的要求。

本公开的实施例提供一种计算机可读存储介质，所述计算机可读存储介质上存储有计算机程序，所述计算机程序被处理器执行时用于实现根据本公开的实施例的跨版本升级方法，例如，参照图1或图2所述的跨版本升级方法。
