具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例一
图1为本发明实施例一所提供的网络设备的结构示意图，如图1所示，该网络设备，可以连接多个终端设备，所提供的网络设备包括上行接口单元503、主控单元504、业务单元505、上行接口单元506、备控单元507以及业务单元508。
其中，在所述网络设备中，上行接口单元503、主控单元504以及第一业务单元505设置成第一工作组501，通过第一工作组501连接多个终端设备中的一部分，在主控单元504的控制下通过第一工作组501处理所连接的终端设备与网络侧之间的业务；
网络设备中的上行接口单元506、备控单元507以及业务单元508设置成第二工作组502，通过第二工作组502连接多个终端设备中剩下的一部分，在备控单元507的控制下通过第二工作组502处理所连接的终端设备与网络侧之间的业务。
作为一种实施方式，主控单元504可以通过控制备控单元507来实现对第二工作组的控制，主控单元504和备控单元507之间可以设置管理通道，主控单元504可以通过改管理通道实现对第二工作组的控制。
作为另一种实施方式，第一工作组501可以和第二工作组502分开管理，比如分别独立地连接不同的网络管理设备等，当然在这种架构下，也可以在主控单元504和备控单元507之间设置一个管理通道，也可以通过主控单元504对第二工作组502进行管理，从而实现第二工作组502的双重管理。
在本实施例中，由于第一工作组501和第二工作组502可以独立处理不同用户的业务，因此，主控单元504和备控单元507的设备标识可以不同，设备标识具体可以包括IP地址或者MAC(Media Access Control，媒体访问控制)地址等。
在本实施例中，第一工作组501和第二工作组502所处理的业务类型可以不同，也可以相同。
作为一种实施例，本实施例提供的网络设备可以是DSLAM(Digital  Subscriber Line Access Multiplexer，数字用户线接入复用器)或者OLT(Optical Line Terminal，光线路终端)等接入设备，当然也可以是其他网络设备，如路由设备、终端设备等。
本实施例提供的网络设备，通过将现有的主备链路设置成独立的工作组，连接不同的终端设备，从而可以充分利用网络设备的硬件资源，不同的工作组可以处理不同类型的业务，从而可以提高网络设备处理业务的能力。
实施例二
图2为本发明实施例二所提供的网络中的业务处理方法的流程图。本实施例的方法适用于网络设备所承载的不同用户需运行不同类型的业务的情况。本实施例的方法具体包括如下步骤：
步骤201、根据预配置信息，将网络设备划分为第一工作组和第二工作组，该第一工作组和该第二工作组包括控制单元、上行接口单元和业务单元；其中，该第一工作组和该第二工作组连接不同的用户；该第一工作组的控制单元为主控单元，该第二工作组的控制单元为备控单元；该主控单元用于通过对该备控单元进行控制，对该第二工作组进行控制。
步骤202、该第一工作组和该第二工作组在各自所具有的控制单元的控制下运行不同类型的业务。
具体地，根据该预配置信息对网络设备进行工作组的划分，实际是将该网络设备中各单元模块进行连接配置，使一个工作组内的单元相连接。根据该预配置信息，对网络设备进行工作组的划分，可以是通过在线划分，也可以是离线划分。在本申请中，在线指的是，该网络设备内各控制单元上已连插相应的 单元模块，离线指的是，该网络设备内各控制单元上还未连插相应的单元模块。若在线划分，根据该预配置信息和各个单元模块的标识等，对该网络设备进行连接划分；若为离线划分，根据该预配置信息和该控制单元上各单元模块的预留位置，对该网络设备进行连接划分。需要说明的是，对于离线划分，在根据划分之后的该两个工作组运行不同类型的业务之前，还需在其控制单元上对应位置，连插相应的单元模块。
该网络设备包括两个的控制单元，以使划分后的工作组各自具有一个控制单元。该第一工作组和该第二工作组，两个工作组各自包括控制单元、上行接口单元及业务单元，也就是说，该两个工作组各自相当于一个独立的设备。该两个工作组各组分别可通过其控制单元为该工作组内部各单元模块提供该工作组承担业务的业务配置参数信息、及根据该业务配置信息进行相应业务数据的处理、交换及汇聚，同时还可通过该控制单元为该工作组提供路由协议的配置及管理等。该第一工作组和该第二工作组分别连接不同的用户，而且不同用户的业务需求，由于该两个工作组的业务配置参数，可通过其各自的控制单元提供，从而可使得该第一工作组和该第二工作组根据各自控制单元的该业务配置参数执行对应类型的业务。
本实施例方案，通过将网络设备划分为各自包括控制单元、上行接口单元及业务单元的两个工作组，并通过该两个工作组中的控制单元分别控制对应的工作组运行不同类型的业务，从而使得该网络设备可以支持多种不同类型的业务。
实施例三
图3为本发明实施例三所提供的网络中的业务处理方法的流程图。如图3所示，该实施例方案，上述实施例方案中，优选的，该网络设备包括主控板和备控板，该控制单元为控制板，该备控单元为备控板，该网络设备包括两个上行接口板和至少两个业务板。
对应的，如上所述步骤201中根据预配置信息，将网络设备划分为第一工作组和第二工作组，具体包括：
步骤301、根据业务类型，将该两个上行接口板中一个接口板作为第一上行接口单元，配置为该第一工作组的上行接口单元，将该两个上行接口板中另一个接口板作为第二上行接口单元，配置为该第二工作组的上行接口单元；将该至少两个业务板中至少一个业务板作为配置为第一业务单元，将该至少两个业务板中除该至少一个业务板之外的业务板配置为第二业务单元。
为了维持网络设备的稳定运行需求，网络设备通常都支持主备模式。对于支持主备模式的网络设备来说，包括主控板、备控板。若该网络设备处于主备模式时，通过该主控板控制该网络设备和外部进行业务通信，保证各单元模块的正常运行；该备控板和外部没有业务通信，不承担任何业务负荷。该主控板和备控板在正常运行过程中，具有相同的配置信息，一旦主控板出现故障，便由该备控板进行接替以维持业务正常运行。也就是说，当前网络设备至少具有两个控制板，即主控板和备控板。在不改变现有网络设备的结构的基础上，本实施例方案优选的，将网络设备划分为两个工作组，即第一工作组和第二工作组。主控板可以作为主控单元，可以是配置为该第一工作组的控制单元，也可以是配置为该第二网络设备的控制单元。若该主控单元为该第一工作组的控制单元，备控单元作为第二工作组的控制单元，由于该主控单元在对本工作组内 个单元模块进行控制的基础上，还可通过对该备控单元的控制，对该第二工作组进行业务分配、管理及信息配置等。
将该网络设备划分为第一工作组和第二工作组的，该第一工作组和该第二工作组可分别具有不同的用户群，如该第一工作组对应企业用户群，该第二工作组对应普通用户群。
该上行接口板提供网络接口，以与网络侧相连接；该业务板提供用户接口，实现用户业务的接入、处理和转发等。该网络设备中的一个业务板具有至少一个用户接口，可以接入至少一个用户，而接入同一业务板的用户业务需求相同。
该第一工作组的控制单元为该主控单元，该第二工作组的控制单元为该备控单元，同时还为该第一工作组和该第二工作组分别配置一个上行接口单元，根据业务类型，将该网络设备的业务板分为两部分，即第一业务单元及第二业务单元；其中该第一业务单元的业务板所承载的业务类型与该第二业务单元的业务板所承载的业务类型不同。
进一步地，在上述方案中步骤301中根据预配置信息，将网络设备划分为第一工作组和第二工作组之前，还包括：
步骤302、判断该预配置信息中该第一工作组和该第二工作组对应的配置是否存在耦合。若是(Y)，则执行步骤303；若否(N)，则执行步骤304。
该步骤中所判断的配置耦合，指的是该预配置信息中单元模块的连接耦合。具体来说，同一单元模块，如上行接口单元或业务单元，只可以对应一个控制单元。而且，对于承载不同业务的上行接口单元具有该不同业务所对应的业务信息及硬件配置需求，具有不同业务需求的业务单元具有不同业务所对应的业务传输通道。对于相同或类似业务的业务单元及上行接口单元需配置在同一工 作组内，若出现交叉配置，即为存在耦合。
步骤303、修改该预配置信息，以解除该耦合；根据该修改后的该预配置信息，将该网络设备划分为该第一工作组和该第二工作组。
为保证，划分后的相互独立的各个工作组可以正常传输对应业务数据，若存在耦合，需待接触耦合之后，重新对该网络设备进行工作组的划分。
步骤304、根据该预配置信息，将该网络设备划分为该第一工作组和该第二工作组。
该实施例方案，在现有网络设备内部结构和网络架构的基础上，进行工作组的划分，可更好的保证所划分的工作组的正常运行，同时在工作组运行业务之前，进行连接耦合的判断，从而更好的保证业务数据的正常传输。
实施例四
图4为本发明实施例四所提供的网络中的业务处理方法的流程图。如图4所示，进一步地，上述方案的步骤202中该第一工作组和该第二工作组在各自所具有的控制单元的控制下运行不同类型的业务之前，还包括：
步骤401、对该第一工作组和该第二工作组进行激活。
为保证所划分的工作组各单元模块之间的连接有效，且可以正常通信，从而保证业务的正常进行，在运行对应业务之前，至少还应对该划分的工作组进行激活。
优选的，在上述步骤401中对该第一工作组和该第二工作组组进行激活之前，还包括：
步骤402、判断该主控单元和所述备控单元是否存在设备标识冲突。
步骤403、若该主控单元和该备控单元存在设备标识冲突，该主控单元向该备控单元下发新的设备标识。
具体地，对于常用的主备模式的网络设备，为保证备控板在接替主控板可以正常的工作，通常为该主控板和该备控板配置相同的设备标识，以使与控制板相连接的上行接口板及业务板可以准确识别，从而准确的进行业务信息的处理。然而在本实施例中根据不同的控制板，也就是控制单元的设备标识来识别不同的工作组。因而，在该实施例方案中，在对该至少两个工作组进行激活，从而运行业务之前，首先应确保该至少两个工作组不存在标识冲突。若该至少两个工作组存在标识冲突，即该至少两个工作组所对应的控制单元具有相同的设备标识，可通过主控单元，即主控板向该备控单元，即备控板下发新的标识。该主控板可以是通过主备管理通道向该备控板下发。
上述方案中，设备标识包括互联网协议(Internet Protocol，简称IP)地址或介质接入控制(Media Access Control，简称MAC)地址；
对应的，上述步骤403中主控单元向该备控单元下发新的设备标识，具体包括：
该主控单元向该备控单元下发标识更改信息，以使该备控单元根据该标识更改信息获取新的IP地址信息，或，根据该标识更改信息，恢复该备控单元的缺省MAC地址。
具体地，该标识更改消息包括新的IP地址，或更改指示消息。该主控单元可以是将重新动态生成新的IP地址通过该标识更改消息下发至该备控单元，也可以是，该备控单元在接收该标识更改消息之后，主动生成新的IP地址，并告知该主控单元。
可选的，该标识更改消息还包括缺省恢复指示消息。由于设备或单元的MAC地址，为生产商在制作过程中烧录在其内部的硬件地址，具有唯一性。然而，对于主备模式的网络设备来说，为使得其主控板和备控板具有相同的MAC地址，通常为备控板虚拟一个与主控板相同的MAC地址。在本实施例中，备控单元在接收到主控单元所下发的该缺省恢复指示消息，对该备控单元的设备标识恢复至默认的MAC地址，也就是具有唯一性的出厂MAC地址。
图5为本发明实施例四中对工作组进行激活的方法流程图。如图5所示，进一步地，上述方案中步骤401中对该第一工作组和该第二工作组进行激活，具体包括：
步骤401a、该主控单元将该备控单元的标识信息发送至该第二上行接口单元及该第二业务单元。
该标识信息可以是IP地址或MAC地址均可。由于，此时还未对划分后的工作组内的单元模块进行重启，因此，主控单元可以是通过该主控单元与该备控单元之间的主备管理通道将该标识信息下发至该该第二上行接口单元及该第二业务单元，以使该第二工作组内单元模块在重启之后，该第二上行接口单元及该第二业务单元可以与该备控单元建立通信连接。
步骤401b、分别对该备控单元、该第二上行接口单元及该第二业务单元进行重启。
具体地，在该网络设备内部，该备控单元、该第二上行接口单元及该第二业务单元所所对应的备控板、上行接口板及业务板均是作为独立的单板插接在该网络设备上。在各单板均具有重启功能，可以是通过选中重启操作软件控制该些单板重启，也可以是通过按下各单板上重启按钮，来实现重启。
步骤401c、该主控单元关闭与该第二上行接口单元及该第二业务单元的连接端口。
对于支持主备模式的网络设备，其网络设备内部各上行接口单元及业务单元均与该主控单元相连接，然而对于该第一工作组和该第二工作组，为保证业务数据的正确传输，上行接口单元和业务单元仅可以与其所配置的工作组内的控制单元相连接。由于该第二上行接口单元和该第二业务单元均为该第二工作组的单元，因此该主控单元需要关闭与其的连接。
步骤401d、待该备控单元重启完毕，该备控单元建立与该主控单元之间的工作组管理通道；该工作组管理通道用于将该主控单元下发的业务配置信息下发至该备控单元，以使该备控单元在接收到该业务配置信息之后，关闭与该第一上行接口单元及该第一业务单元的连接端口。
由于该备控单元、该第二上行接口单元及该第二业务单元均作为单板进行重启，对于不同的单板，由于其内部结构及重启进程的不同，其重启时间业务不尽相同。该备控单元重启完毕，该主控单元便恢复与该备控单元的通信，也就是说该主控单元可以和该备控单元进行数据传输。该备控单元在重启过程中，该备控单元中断与单元模块的通信连接。待重启完毕，该备控单元通过向该主控单元发送建立请求消息，尝试与该主控单元重新建立连接。该主控单元在接收到该备控单元所发送的请求消息，与该备控单元建立双向通信连接，该通信连接，即为该工作管理通道。
该主控单元可通过该工作管理通道向该备控单元下发业务配置信息，该业务配置信息包括该第二工作组运行对应业务，该备控单元、该第二上行接口单元及该第二业务单元需配置的参数信息。在该第二工作组的激活过程中，该备 控单元在接收到该业务配置信息之后，确认该第二工作组对应的业务与该第一工作组所对应的业务类型不同，获知该网络设备处于工作组负担模式，而非主备模式，因此该备控单元还需关闭该第一上行接口单元及该第一业务单元的连接端口，从而更高的保证业务数据的准确传输。
需要说明的是，该备控单元在该第二工作组进行激活建立连接之后，运行业务的过程中，还可周期性的检测该工作管理通道的状态，如发现通道传输中断等，记录分析该发生中断的原因，并重新尝试建立连接。由于该第一工作组与该第二工作组的相对独立性，在该第二工作组该第二业务单元仅与该备控单元建立通信连接，该备控单元仅与该主控单元之间存在工作组管理通道的连接；而对于，该第一工作组内部的该第一上行接口单元、该第二业务单元也仅与该主控单元存在通信连接。也就是说，该第一工作组和该第二工作组在实现物理上的结构独立的基础上，其各自的业务通信也相对独立，其互不干扰。该主控单元可对该第一工作组所运行业务进行相应的管理控制，可对该第二工作组下发业务配置信息，该第二工作组在接收该业务配置信息之后，根据该业务配置信息对该第二工作组所运行业务进行相应的管理控制。
在对该第二工作组进行激活之后，对该第二工作组内的配置信息、及该主控单元及该备控单元的标识信息等进行复查。在对该第二工作组进行激活之后，该第一工作组与该第二工作组已实现结构独立和业务独立，也就是物理和逻辑的独立的基础上，若该第二工作组所配置的用户业务发生变更或升级，可由该主控单元向该备控单元下发新的业务配置信息，并根据该新的业务配置信息进行对应参数的修订。
对于结构及业务独立的工作组，可以使用完全不同的网络部署和配置方案， 从而有针对性的为不同的用户群提供不同类型的业务体验。举例来说，对于普通的用户群可通过该第一工作组，基于传统的流量部署方案运行业务，而对于具有高宽带、高流量的特殊用户群，则通过该第二工作组，基于高速宽带的流量部署方案来运行高速率要求的业务。
本实施例方案在上述方案的基础上，在该第一工作组和该第二工作组运行相应类型的业务之前，通过工作组的激活，更好的保证该第一工作组和该第二工作组的独立性，从而更好的保证该第一工作组和该第二工作组所运行业务的准确性。同时，由于该网络设备划分后的工作组的物理和逻辑之间的独立，可对工作组进行独立软硬件升级，从而满足用户的差异化需求。
实施例五
图6为本发明实施例五所提供的网络中的业务处理方法的流程图。如图6所示，该方法，具体通过对软件进行升级以实现新业务进行具体说明，具体包括如下：
步骤601、通过管理***将具有新特性的软件单独下发至该第二工作组，并暂停所运行的业务。
需要说明的是，由于该新特性的软件仅下发至该第二工作组，因此该第一工作组正常运行已有业务，该第二工作组在接收到该新特性的软件后，需中断所运行的业务。
步骤602、激活该第二工作组所接收到的该新特性的软件，该第二工作组中该备控单元、该第二上行接口单元和该第二业务单元完成升级。
具体地，该第二工作组完成软件版本的升级后，其所配置的用户信息不变。 该第二工作组进行软件的升级，可以是通过自动升级适配来实现。
步骤603、该第二工作组根据该新特性的软件运行业务。
该第二工作组根据该新特性的软件运行之前所配置用户的业务，该业务由于软件的升级，为之前业务的升级业务。
若该主控单元504由于设备老化性能减弱已无法满足该第一工作组501所配置业务的需求，则需将该主控单元504的主控板替换掉即可。替换主控板之后，根据原主控板的配置信息通过对该新的主控板进行配置，从而对该主控单元504进行业务的重新配置。卸下原主控板，该备控单元507在检测到工作组管理通道中断后，记录该中断的原因，并周期性的发起连接请求。当***新主控板，且该第一工作组重新恢复业务之后，重新建立新的工作组管理通道。
然而，随着用户需求的不断变化，所有用户的需求都得到提高，从而使得用户需求不均衡化得到缓解。那么，还可通过删除工作组的方式，使得该网络设备恢复至原有的主备模式。
删除工作组的方法可以是该建立独立工作组的反过程来实现。从划分的工作组模式，恢复至主备模式，实际主要是打开该主控单元与该第二上行接口单元及该第二业务单元的接口，该备控单元打开与该第一上行接口单元及该第一业务单元的接口，从而使得该主控单元可以与所有的上行接口单元及该业务单元建立连接。需要说明的是，将该网络设备恢复至主备模式，还需通过该主控单元为备控单元下发MAC地址或IP地址，保证该备控单元与该主控单元的MAC地址或IP地址相同；通过该主控单元为第二工作组的该备控单元下发配置，备控单元将该配置发送至该第二上行接口单元及该业务单元，以使该第二上行接口单元和第二业务单元删除原有的控制单元标识信息，重新进行控制单元的选 择，与该主控单元建立连接。将该网络设备恢复至主备模式，还需对该网络设备各单元模块进行重启，并重新建立主备管理通道。
本实施例方案，在满足用户需求差异化的基础上，还可通过对运行特定业务的工作组进行部署配置，减少对该整个网络设备进行部署配置所造成的资源浪费。
需要说明的是，本发明实施例方案由于工作组之间物理及逻辑的独立，因此运营商可将其中一个工作组，如该第二工作组租赁给企业或个人，实现业务的独立管理和运营，同时还可优先升级其中一个，为新技术应用或网络部署的提供可靠的试验环境。
实施例六

优选的，该网络设备701包括主控板和备控板；主控单元704包括该主控板；备控单元705包括该备控板；网络设备701包括两个上行接口板和至少两个业务板；
