Description
本文涉及多处理机的分布式***，尤其涉及一种主控板的升级方法及装置。
随着信息时代的来临，PC电脑的普及，以及互联网的广泛应用，电脑信息技术与各行各业进行了有效的结合，各种新技术、新业务不断涌现，用户对于数据的带宽需求都越来越高。为了满足单个用户高带宽的需求，运营商要求网络设备具有大容量、高接入和高处理性能。为了达到大容量、高接入和高处理性能的需求，目前的网络设备多采用部署大量的CPU的分布式***。随着多处理机的分布式***在电信行业逐渐推广和大规模使用，以及用户对网络设备性能需求的提高，设备的软件升级更加频繁。
相关技术实现设备软件升级的方法是：待升级设备是一台具有一块全局主用主控板、一块全局备用主控板以及若干块接口板的分布式设备。(1)在全局主用主控板正常运行的情况下，升级全局备用主控板，创建版本回滚定时器；(2)进行主备倒换，让已经升级的备用主控板成为新的全局主用主控板，接替原全局主用主控板工作，并升级所有接口板；(3)进行步骤(2)时版本回滚定时器超时，则升级失败，进行版本回退，升级结束；否则确认新全局主用主控板的升级操作，版本回滚定时器被删除；(4)依次升级其他主控板；(5)直到所有单板都升级到新版本，升级过程结束。该方法存在以下不足：一、无论是主控板的主备倒换失败，还是任何一块接口板的升级失败都会导致整个升级的失败，增大了设备升级失败的概率；二、在接口板升级的过程中，由于接口板的CPU会被重启，使得由接口板CPU发送的协议报文需要由主控板CPU代理发送，主控板CPU本身的业务繁忙，同时控制设备升级过程，可能无法及时代理发送接口板CPU发送的协议报文，导致网络拓扑发生震荡。

全局备用主控板102，主要用于请求并加载升级数据，升级并运行正常后确认升级操作，隔离同全局主用主控板及其他未升级单板的内部通讯，转换为主用主控板，代理发送接口板n1-nN由于软件升级，CPU重启而无法发送的协议报文。
接口板n1-nN，主要用于请求并加载升级数据，在升级过程中，由于CPU重启而无法发送的协议报文由升级后的原全局备用主控板代理发送，N为大于1的正整数。
如图2所示，本发明实施例的待升级设备在升级过程中设备内部通讯网络的链接结构包括：
全局主用主控板201，主要负责设备升级过程的控制。其中存储着软件升级数据，并安装了软件升级数据管理模块，可与其他单板通过内部通讯网络交互，将其存储的软件升级数据通过内部通讯网络加载到其他单板中。

接口板n4，通过内部通讯网络同全局主用主控板201相连，隔离同升级后的备用主控板202及升级后的接口板m3的通讯。同时，等待全局主用主控板201发起单板升级，
如图3所示，双主控隔离的逐板升级方法流程如下：
处于备用状态的主控单板其升级模块的设计与普通待升级接口板相同。
步骤1：全局主用主控板向全局备用主控板发送版本升级请求；

步骤10：接口板n升级成功，隔离同全局主用主控板及其他未升级接口板的内部通讯，建立同升级后的全局备用主控板及其他已升级接口板的内部通讯，开始升级后接口板的工作；
步骤11：重复上述接口板n升级过程，直到所有接口板升级成功完成；
步骤12：全局主用主控板转换为全局备用主控板，建立同升级后的全局备用主控板及其他升级后的接口板的内部通讯，进行软件升级，升级过程结束。
在本实施例中，首先进行全局备用主控板的升级，待全局备用主控板升级成功后，依次进行接口板的升级。在进行接口板的升级时，可以根据回滚定时器设定的时间依次对接口板进行升级，如果一个接口板在规定的时间内未成功升级则可先进行下个接口板的升级操作。当然，在其它的实施例中接口板的升级顺序可以做相应的调整。

本领域普通技术人员可以理解上述实施例的全部或部分步骤可以使用计算机程序流程来实现，所述计算机程序可以存储于一计算机可读存储介质中，所述计算机程序在相应的硬件平台上(如***、设备、装置、器件等)执行，在执行时，包括方法实施例的步骤之一或其组合。
可选地，上述实施例的全部或部分步骤也可以使用集成电路来实现，这些步骤可以被分别制作成一个个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。
上述实施例中的装置/功能模块/功能单元可以采用通用的计算装置来实现，它们可以集中在单个的计算装置上，也可以分布在多个计算装置所组成的网络上。
上述实施例中的装置/功能模块/功能单元以软件功能模块的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。上述提到的计算机可读取存储介质可以是只读存储器，磁盘或光盘等。
本发明实施中，全局备用主控板升级成功后，隔离同主用主控板及其他未升级单板之间的通讯，转换为主用主控板，此时设备中存在两个互不干扰
的***，即以原主控板为全局主用主控板的***1和以升级后的主控板为全局主用主控板的***2。升级过程中任何一个步骤自身的失败都不会独立导致整个升级过程的失败，提高了升级成功的概率。此外，在设备升级过程中，全局主用主控板不必兼顾控制软件升级过程和代理发送升级接口板CPU发送的协议报文，减轻了全局主用主控板CPU的负担，避免由于代理发送接口板CPU发送的协议报文延时而导致拓扑震荡。
