Description
本公开涉及通信领域，尤其涉及一种网元设备及其传输模式配置装置和方法。
时钟时间传送是电信设备的必需功能，在波分电信设备组网中，需要配备三层监控单板，为网元之间的通信提供路由和转发网元之间的数据报文。在三层监控单板上，由于面板上需要布置多个OSC(Optical Supervisory Channel,光监控信道)面板口，无法再设计外时钟口，因此通常需要接口板来配合使用。常用的带外接口带外传送时钟时间报文的场景如图1所示，通过接口板的外时钟口和1PPS(Pulse Per Second，每秒脉冲数)+TOD(Time of Day，时间信息)口分别接入时钟和时间信息，接口板将这些信息封装成时钟时间报文透明发送给本网元的监控板，然后经由监控板的OSC口传送到下游网元，从而实现同步下游网元的时钟时间。但目前图1所示的网元设备上的接口板仅支持带外传输模式，当用户业务需要通过带内传输时，则图1所示的组网无法满足该业务需求。例如，如果用户业务从客户侧接入，通过PTP(Picture Transfer Protocol，图片传输协议)协议将时钟时间报文使用OTU(Optical Transform Unit，光转换单元)帧封装，经带外接口传送到下一网元，图1所示的组网就无法满足该业务需求。

下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例只是本公开中一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
实施例一：
本实施例中，参见图2所示，在网元设备上依次连接的业务板1、时钟板2和接口板3，网元设备还包括与接口板3连接的监控板4。其中，业务板1通过第一接口与上游时钟源设备连接，接口板2通过和第二接口与上游时钟源设备连接。本实施例中的上游时钟源设备可以是上游网元设备，或者产生时钟源的各种仪表设备。本实施例中的第一接口可以太网接口，例如GE(Gigabit Ethernet，千兆位以太网)/10GE接口。
本实施例中对于网元设备上接口板3当前是用带外传输模式还是带内传输模式可以由组网人员根据当前组网需求灵活确定。并在确定好之后通过传输模式配置终端向网元设备下发包含配置指令和待配置接口板3的唯一标识信息的模式配置报文。例如可以下发给网元设备的控制板(图中未示出)，由控制板根据模式配置报文中待配置接口板3的唯一标识信息在本网元设备上找到对应的接口板3并将该模式配置报文进行下发。本实施例中的传输模式配置终端可以采用任意能向接口板3下发配置指令的终端，例如CLI(command-line interface，命令行界面)终端或者网络管理服务器等。
基于上述设置，对网元设备接口板3传输模式的配置方法包括：
接收到传输模式配置终端下发的模式配置报文后，判断模式配置报文包含的是带外模式配置指令还是带内模式配置指令，为带外模式配置指令时，将接口板3传输模式配置为带外传输，并启用第二接口，也即启用直接与上游时间源设备连接的第二接口；当配置报文包含带内模式配置指令时，将接口板3的传输模式配置为带内传输并启用时钟板，此时上游时钟源设备—业务板—时钟板—接口板3这条链路被启用。启用时钟板还包括启用时钟板的时间校准功能。以上过程可以由接口板3自身完成。也即接口板3接收到传输模式配置终端下发的模式配置报文后，按照上述过程完成对自身传输模式的配置。
本实施例中，传输模式配置终端通过控制板发给接口板3的报文可能会有多种，例如时钟配置报文、时间配置报文、端口属性配置报文等，对于不同的报文其里面所含的报文唯一标识(例如命令码)不同。接口板3接收并处理模式配置报文的过程参见图3所示，包括：
S301：接口板3接收到各种报文后，从各种报文中识别出模式配置报文，例如可根据报文唯一标识进行识别。
S302：接口板3对识别出的模式配置报文进行解析，提取出其中的模式配置指令和接口板的唯一标识信息，根据该唯一标识信息可以判断是否是发给自己的模式配置报文，如果不是，则不作任何处理。
S303：接口板3在确定是发给自己的模式配置报文后，根据解析出的模式配置指令(带外模式配置指令或带内模式配置指令)进行对应的传输模式配置。本实施例中，接口板3在进行传输模式配置时，包括如果之前已有配置好的传输模式，则将之前的传输模式的配置清除，然后进行新传输模式对应的配置信息进行设置、保存和以及对相应的硬件(例如相应的可变成逻辑器件)配置，且在新传输模式为带内传输模式时，还包括启动时钟板的时间校正功能。例如发时间校正通知给时钟板触发时间校正功能。
本实施例中，当接口板3当前配置的是带内传输模式时，接口板3启用时钟板后，还包括接收时钟板按预设时间同步规则下发的对时时间通知报文，该对时时间通知报文中包含标准时间信息。接口板3收到该对时时间通知报文后，提取当前的本地时间信息与对时时间通知报文中的标准时间信息进行比对，根据比对结果对本地时间信息进行校正。例如可以将本地时间信息与标准时间信息做减法运算，根据减法得到的结果对本地时间信息进行相应的校正。
本实施例中，接口板3从时钟板2接收到的报文也可能包括多种，例如时间等级报文、1PPS+TOD报文等，不同报文中携带的协议标识不同。因此可以根据协议标识对各报文进行识别。时钟板2例如可以通过背板时钟通道向接口板3发送报文。其中，接口板3接收并处理对时时间通知报文的情况过程参见图4所示，包括：
S401：接口板3接收报文，并根据报文中的协议标识从中识别出对时时间通知报文。
S402：接口板3按照一定的扫描周期扫描是否接收到的对时时间通知报文。如没有扫描到，可以继续扫描；且可以在连续的几次都未扫描到时进行相应的报警。
S403：接口板3根据扫描到的对时时间通知报文按上述过程对本地时间进行校正。
通过上述过程，接口板3将传输模式配置为带外传输时，则通过第二接口接收来自上游时钟源设备的时间信息和时钟信息，并组装成时间时钟报文发送给监控板4，经由监控板传送到下游网元。可选的，本实施例中的第二接口包括外时钟接口和1PPS+TOD接口。
接口板3将传输模式配置为带内传输时，业务板1接收来自上游时钟源设备的时间时钟报文并发送给时钟板2；时钟板2将接收的时钟时间报文下发给接口板3；接口板3将来自时钟板的时钟时间报文发送给监控板4，经由监控板4传送到下游网元设备。监控板4例如可通过其OSC口将时钟时间报文下发给下游网元设备。
本实施例中网元设备的接口板可以根据自身当前在组网中的角色确定当前使用带外传输模式还是带内传输模式，也即接口板支持带内、带外两种传输模式的配置和切换，提升了接口板的处理能力，实现简单，通用性好。

协议报文接收单元521，用于接收来自时钟板的报文，并从接收到的各报文中识别出对时时间通知报文。协议报文接收单元521从时钟板和其他地方接收到的报文也可能包括多种，例如时间等级报文、1PPS+TOD报文，其例如可以通过报文中的协议标识对各报文进行识别。
参见图8所示，本实施例中的时钟板包括定时发送对时报文模块81，用于定时向协议报文接收单元521发送对时时间通知报文。

对时校正单元523，用于提取定时检测对时报文单元检测到的对时时间通知报文中的标准时间信息，以及提取接口板当前的本地的时间信息与标准时间信息进行比对，根据比对结果对接口板本地时间信息进行校正。例如对时校正单元523可以将本地时间信息与标准时间信息做减法运算，根据减法得到的结果对本地时间信息进行相应的校正。
应当理解的是，上述配置模块51中的配置报文接收单元511、模式报文解析单元512、模式设置单元513以及时间校正模块52中的协议报文接收单元521、定时检测对时报文单元522、对时校正单元523的各功能可以通过接口板中的各子模块来实现。通过上述各模块单元对接口板的传输模式设置好之后，接口板即可根据设置使用带外或带内传输模式进行相关业务的处理。
本公开实施例根据接口板在组网环境中的角色，确认接口板是使用带外模式还是带内模式，然后通过传输模式配置终端将对应的模式配置报文配置到接口板上，接口板在完成对应的配置生效和一系列模式初始化后，就可运行在配置的工作模式下。如果工作在带外模式下，则不需要运行校时算法，直接透传面板口接收的时钟时间报文，发送给本网元的监控单板上；如果工作在带内模式下，网元的时钟板通过背板网络接口定时发送当前的标准时间信息，接口板需要同时对接收报文检测，并对接收到的对时报文进行解析得到标准时间信息，然后与本地时间信息进行比较计算，并将计算结果校正到本地时间中，完成带内模式下网元内同步时钟时间的功能。
以上内容是结合具体的实施方式对本公开实施例所作的进一步详细说明，不能认定本公开的具体实施只局限于这些说明。对于本公开所属技术领域的普通技术人员来说，在不
脱离本公开构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本公开的保护范围。
本公开实施例在网元设备上增设实现带内传输的业务板和时钟板硬件基础，然后根据接收传输模式配置终端下的配置报文确定接口板是采用带外传输模式还是带内传输模式，在现有网元设备单板基础之上，增加了接口板的处理能力和灵活性，能更好的使用业务需求，且实现简单，成本低，通用性好。
