具体的，在用户侧(UNI，User Networks interface)，业务集中处理板的报文处理模块将多块不同业务接口板传送来的窄带业务进行流分类、入口速率限制、二层(L2，Lever 2)交换、多协议标签交换(MPLS，Multi Protocol Label Switching)、服务质量(QoS，Quality of Service)处理、报头信息修
改、流量调节等处理，然后，输出报头修改信息的索引，采用自定义的私有报头送入后级的交换接入模块，所述交换接入模块完成输入的报头解析、队列控制、报文的切片和负荷分担、调度和空间组播等处理，最后送入交换网络；或者，业务集中处理板的交换接入模块接收来自交换网络的窄带业务的信元，先对信元排序重组，完成报文的恢复，然后将重组的窄带业务的报文传送至报文处理模块，进行媒体访问控制(MAC，Media Access Control)地址学习、报文修改、调度等处理，最后通过背板将窄带业务的报文传送到业务接口板，通过业务接口板将窄带业务的报文发送到外部网络。
这里，所述业务接口板的作用是从外部网络接入各种窄带业务，经过处理后封装成指定报文格式后通过背板传送到业务集中处理板进行处理；或是通过背板接收来自业务集中处理板的窄带业务，按照指定的传输承载协议处理后发送到外部网络；所述指定报文格式为业务接口板与业务集中处理板预先约定的报文格式；所述指定的传输承载协议为发送到外部网络所需要的传输承载协议。
步骤202：在网络侧，业务集中处理板将面板传送来的宽带业务进行处理和转发，或者，将交换网络传送来的宽带业务进行处理后传送到面板的光接口。
具体的，在网络侧(NNI，Networks-Networks interface)，业务集中处理板的报文处理模块将面板传送来的宽带业务进行流分类、入口速率限制、L2交换、MPLS交换、QoS处理、报头信息修改、流量调节等处理，然后，输出报头修改信息的索引，采用自定义的私有报头送入后级的交换接入模块，所述交换接入模块完成输入的报头解析、队列控制、报文的切片和负荷分担、调度和空间组播等处理，最后送入交换网络；或者，业务集中处理板的交换接入模块接收来自交换网络的宽带业务的信元，先对信元排序
重组，完成报文的恢复，然后将重组的宽带业务的报文传送至报文处理模块，进行MAC地址学习、报文修改、调度等处理，最后将宽带业务的报文传送到面板的光接口。
所述业务集中处理板还在接收到从面板和交换网络传送来的业务时，对所述业务的报文进行解析，根据解析到的地址确定所述业务是宽带业务还是窄带业务，其中，当解析到的地址为自身地址时，确定所述业务为从面板方向传送来的宽带业务，当解析到的地址不是自身地址、且为宽带业务板地址时，确定所述业务是宽带业务，当解析到的地址不是自身地址、且为窄带业务板地址时，确定所述业务是窄带业务。
本实施例中，所述业务集中处理板还对多块不同业务接口板进行1：N保护控制，具体的，业务集中处理板的管理控制模块接收各业务接口板在上电时发送的在位信号，通过所述各在位信号确定各业务接口板在位，并扫描各业务接口板是否发生故障，在有业务接口板发生故障时，给处于保护状态的业务接口板发送一个1：N倒换信号，使处于保护状态的业务接口板处于工作状态，对故障的业务接口板发送一个复位信号，这样，不致引起业务的中断。
上述的报文处理模块、交换接入模块和管理控制模块如图4所示，可以集成为一个混合业务处理模块，这种方式为集中式。
所述业务集中处理板与多块不同业务接口板间均通过5组信号连接，如图5所示，分别是传送业务用的TD+/-和RD+/-信号和控制管理用的1：N倒换信号(该信号和业务集中处理板对业务接口板的复位信号(RESET)复用)、业务接口板在位信号以及主备处理板指示信号。
为了提高可靠性，本实施例的方法还包括：为所述业务集中处理板设置备用业务集中处理板，形成主用业务集中处理板和备用业务集中处理板的1+1保护，如图6所示，所述主用业务集中处理板和备用业务集中处理
板在上电时均给各业务接口板发一个主备处理板指示信号，告知各业务接口板哪块业务集中处理板处于主用状态，哪块业务集中处理板处于备用状态，当主备倒换触发条件发生时，备用业务集中处理板通过与主用业务集中处理板进行主备协商，获得主用地位，然后通告所有窄带业务板和业务接口板，窄带业务板将业务发送到新的主用业务集中处理板上，业务接口板将业务总线的收发选择到新的主用业务集中处理板上，新的主用业务集中处理板与交换网络间不进行窄带业务的转发，仅进行宽带业务的转发，并且，新的主用业务集中处理板和原主用业务集中处理板不对各自的宽带业务进行倒换，都要对接收到的宽带业务进行处理和转发。这里，业务集中处理板的主备状态通过单板之间的互连线进行协商，协商结果通过硬连线发送给业务接口板。
主备倒换触发条件包括以下任一种：1)主用业务集中处理板的用于主备倒换的微动开关打开；2)主用业务集中处理板硬复位；3)主用业务集中处理板硬件故障；4)主用业务集中处理板软件故障，如主用业务集中处理板的CPU未定期发送保活信号，或发送保活信号的周期比软复位的重启的时间还长；5)强制命令或人工倒换。
如图7所示，所述报文处理模块可以由网络处理器HX320来实现，该网络处理器HX320工作核心频率为240M，支持100G的双向全双工最小包长业务的线速处理，最大接入流量为100G，支持40个串行千兆介质无关接口(SGMII，Serial Gigabit Media Independent Interface)，业务接口板通过SGMII接口总线把业务传送入业务集中处理板，在本实施例中，最多能同时处理24种不同类型的窄带业务，如：可以有欧洲数据传送格式1(E1，European digital transmission format)2.048Mbps类型的窄带业务，也可以有异步传输模式(ATM，Asynchronous Transfer Mode)类型的窄带业务；线路侧，可以从面板方向接收16路的宽带业务；交换接入模块可以交换接入
芯片SA40实现，由网络处理器HX320与交换接入芯片SA40之间通过16对Serdes作为1组Interlaken接口连接；交换接入芯片SA40通过16对高速Serdes连接背板；管理控制模块可以由现场可编程门阵列(FPGA，Field－Programmable Gate Array)来实现。
在业务集中处理板与业务接口板进行业务交互时，上行方向：来自业务接口板的报文通过背板的SGMII接口送入处于主用的业务集中处理板的网络处理器HX320，进行业务流的分类、报文解析、入口速率限制、MPLS交换、QOS处理、报头信息修改、流量调节等处理，之后通过Interlaken接口将报文送入后级的交换接入芯片SA40，进行输入的包头解析，队列控制、包的切片和负荷分担、输出侧发起的调度和空间组播等处理，最后通过16对6.25G背板Serdes送入交换网络。
下行方向：处于主用的业务集中处理板的交换接入芯片SA40通过6.25G背板总线接收来自交换网络的信元，对信元排序重组，完成报文的恢复，重组的报文通过Interlaken接口送至网络处理器HX320，进行MAC地址学习、报文修改、调度等处理，最后通过SGMII接口送到业务接口板，在业务接口板上完成业务承载协议的处理后发送到外部网络。

所述业务集中处理板还包括主备协商模块84，配置为当与备用业务集中处理板形成1+1保护、且主备倒换触发条件发生时，与备用业务集中处理板进行主备协商。
