通信系统及板卡配置方法
相关申请的交叉引用
本公开要求于2019年10月12日提交中国专利局的申请号为CN201910970768.4、名称为“通信系统及板卡配置方法”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本公开涉及通信技术领域，具体而言，涉及一种通信系统及板卡配置方法。
背景技术
在数据通信领域，为了构建简单且成本低的通信系统，一般采用全网状架构，即FULL-MESH架构。在FULL-MESH架构的机架式交换机中，一般只有业务卡之间直接传输数据，即业务卡之间通过FULL-MESH背板连接，业务卡之间的数据通过卡间直连通道传输。
这种架构中，业务卡之间在传输数据时只能有1组数据通道，使得其传输带宽大大受限。为了提高传输带宽，通常需要成倍增加业务卡的数据通道或者引入交换卡，以实现业务卡之间更大带宽的数据交换。
但是，在不同的网络需求下业务卡和交换卡各自的数量需求也不同，而在FULL-MESH架构中，需要工作人员在FULL-MESH的槽位中增加或减少业务卡或交换卡的数量，这需要浪费较多的时间，使得无法根据实际需求随意改变交换卡或业务卡的数量，给通信系统的构建带来了一定的限制。

本公开的其他特征和优点将在随后的说明书阐述，并且，部分地从说明书中变得显而易见，或者通过实施本公开实施例了解。本公开的目的和其他优点可通过在所写的说明书、权利要求书以及附图中所特别指出的结构来实现和获得。
附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对本公开实施例中所需要使用的附图作简单地介绍，应当理解，以下附图仅示出了本公开的某些实施例，因此不应被看作 是对范围的限定，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他相关的附图。

具体实施方式
下面将结合本公开实施例中附图，对本公开实施例中的技术方案进行清楚且完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本公开实施例的组件可以以各种不同的配置来布置和设计。因此，以下对在附图中提供的本公开的实施例的详细描述并非旨在限制要求保护的本公开的范围，而是仅仅表示本公开的选定实施例。基于本公开的实施例，本领域技术人员在没有做出创造性劳动的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。
本公开实施例提供的至少一个实施例中，可以根据实际需求灵活配置对应数量的复用板卡为交换卡或业务卡，进而使得网络插入更加灵活便捷。
请参照图1，图1为本公开实施例提供的一种通信系统100的结构示意图，该通信系统100包括主控卡110以及多个复用板卡120，主控卡110通过FULL-MESH背板130与多个复用板卡120连接，多个复用板卡120之间通过FULL-MESH背板130连接。
主控卡110，用于对多个复用板卡120中每个复用板卡120进行配置，以将所述每个复用板卡120配置为交换卡或业务卡。
配置的业务卡，用于与所述交换卡之间进行业务数据的传输。
配置的交换卡，用于将所述业务卡之间的业务数据进行跨卡转发，即接收业务卡传输的业务数据，并将该业务数据进行转发。
其中，FULL-MESH表示网络的一种连接方式，即所有节点之间都直接连接，在FULL-MESH背板130中的插槽可以支持插入交换卡，也可以支持插入业务卡。FULL-MESH背板130中的各个端口之间预先通过布线进行连接，所以，其板卡之间的连接与交换均要通过该FULL-MESH背板130，也即主控卡110和多个复用板卡120之间通过该FULL-MESH背板130连接，如主控卡110可以通过管理总线与FULL-MESH背板130连接，以及多个复用板卡120之间通过FULL-MESH背板130中端口进行连接。
可以理解地，复用板卡120并不是单独指交换卡或业务卡，而是具有交换卡和/或业务 卡的功能，即复用板卡120可以作为交换卡，或者可以作为业务卡，或者两种均可。由于复用板卡120既可以作为交换卡也可以作为业务卡，所以，若该通信系统100中只需要采用一种类型的多个复用板卡120就可以实现交换卡与业务卡之间的数据传输，则可以大大减少通信系统100中的板卡类型，提高产品的灵活性。
当然，本公开实施例中，可以在FULL-MESH背板130中只插入复用板卡120，或者插入复用板卡120和正常的业务卡，在这些情况中，复用板卡120既可以作为交换卡，也可以作为业务卡。本发明实施例中提到的正常的业务卡主要是区分于由复用板卡用于的业务卡。
若其中一部分数量的复用板卡120作为业务卡时，某一业务卡需向另一业务卡传输业务数据时，该业务数据需通过交换卡进行转发，交换卡接收业务数据后，从业务数据中获取其携带的需转换的目的业务卡(即另一业务卡)，由此可查找与目的业务卡的连接端口，进而可将业务数据从该端口转发给目的业务卡。
需要说明的是，在实际应用中，主控卡110可以将全部的复用板卡120均配置为业务卡，或者将多个复用板卡120中的一部分复用板卡120配置为交换卡，另一部分板卡配置为业务卡。在全部的复用板卡120为业务卡时，业务卡之间可以直接传输数据。在将部分复用板卡120配置为交换卡，另一部分复用板卡120配置为业务卡，这样可以使得业务卡之间的数据传输可以通过交换卡来转发，进而提高业务数据的传输效率。
在上述实现过程中，通过主控卡110可实现配置对应的复用板卡120为交换卡或业务卡，从而可以根据实际需求灵活配置对应数量的复用板卡120为交换卡或业务卡，提高了系统构建的灵活性，且在通信系统100中减少了板卡类型，便于对板卡的维护。
如图2所示，FULL-MESH背板130中提供了用于插卡的多个槽位，每个槽位中设置有多个端口，槽位之间通过端口连接，如第一个槽位中的PORT1端口与第二个槽位中的PORT1端口连接。其中，复用板卡120在作为业务卡时，其可以提供对外接口，以从外部接收业务数据的输入。
每个复用板卡120可以插入到FULL-MESH背板130的槽位中，当然，FULL-MESH背板130中也可以为主控卡110提供相应的槽位，或者主控卡110可以另外设置，主控卡110通过FULL-MESH背板130与FULL-MESH背板130中插入的多个复用板卡120连接即可。
主控卡110可以在检测到FULL-MESH背板130中的槽位中插入有板卡时，配置其中至少一个槽位中的复用板卡120为交换卡以及配置其他槽位中的复用板卡120为业务卡。
可以理解地，在需要建立通信系统100时，主控卡110可以对FULL-MESH背板130 中的每个槽位进行监控，即FULL-MESH背板130中的某个槽位若插入板卡后，FULL-MESH背板130可以向主控卡110发送相应槽位插入有板卡的提示信息，或者板卡也可在插入FULL-MESH背板130后主动向主控卡110发送其已插入FULL-MESH背板130的提示信息，然后主控卡110则可检测到其相应槽位中插入有板卡。其中，为了建立通信系统100的需要，可以设置复用板卡120的数量，即主控卡110可以检测到预设数量的槽位中插入有板卡时，则可选择任意至少一个槽位中的复用板卡配置为交换卡以及配置其他槽位中的复用板卡为业务卡。
也就是说，主控卡110可以根据实际需求配置相应槽位的复用板卡120为交换卡或业务卡，从而可以根据需求对复用板卡120进行配置，更加灵活方便。
作为一种示例，主控卡110还可以获取FULL-MESH背板130中的槽位的槽位信息，然后根据槽位信息按照预设选择规则配置其中至少一个槽位中的复用板卡为交换卡以及其他槽位中的复用板卡为业务卡。其中，槽位信息可以包括每个槽位的序号、或者每个槽位配置的优先级或者每个槽位的带宽等。
在一些实现方式中，预设选择规则可以为选择指定序号的槽位中的复用板卡作为交换卡以及其他指定序号的槽位中的复用板卡作为业务卡，即选择指定槽位中的复用板卡作为交换卡以及选择其他槽位中的复用板卡作为业务卡，例如，图2中从上到下依次对槽位进行编号，其序号依次为1号、2号、3号和4号，可选择1号和2号槽位中的复用板卡120为交换卡，3号和4号槽位中的复用板卡120为业务卡。
在一些实现方式中，预设选择规则可以为根据槽位优先级选择优先级较高的槽位中的复用板卡作为交换卡，选择优先级较低的其他槽位中的复用板卡作为业务卡，例如，上述的4个槽位的优先级从高到低依次为1号、2号、3号和4号，如若需配置两个交换卡，则可选择1号和2号槽位的复用板卡120作为交换卡，3号和4号槽位中的复用板卡120为业务卡。如若需配置1个交换卡，可以只选择1号槽位的复用板卡120作为交换卡，2号、3号和4号槽位中的复用板卡120为业务卡。
在一些实现方式中，预设选择规则可以为根据槽位的带宽选择带宽较高的槽位中的复用板卡作为交换卡以及选择带宽较低的其他槽位中的复用板卡作为业务卡，例如，上述的4个槽位的带宽从高到低依次为1号、2号、3号和4号，如若需配置两个交换卡，则可选择1号和2号槽位的复用板卡120作为交换卡，3号和4号槽位中的复用板卡120为业务卡。
其中，每个槽位的优先级可以根据实际需求配置，如主控卡110可对每个槽位的优先级进行配置，主控可存储每个槽位的序号及其优先级的对应关系；每个槽位的带宽即为端 口的带宽，若端口的带宽为40Gbps，则槽位的带宽也为40Gbps。
例如，如图3所示，图3中配置了两个槽位(SLOT1和SLOT 2)的复用板卡120作为交换卡，其他三个槽位(SLOT3、SLOT 4和SLOT 5)的复用板卡120作为业务卡，每个交换卡均与每个业务卡连接，每个业务卡之间也有对应的连接通道，交换卡之间也配置有连接通道。当然，交换卡和业务卡也可以根据需求灵活配置，如配置两个槽位(SLOT4和SLOT 5)的复用板卡120作为交换卡，其他三个槽位(SLOT1、SLOT 2和SLOT 3)的复用板卡120作为业务卡。
需要说明的是，图3中配置了两个交换卡，使得基于FULL-MESH结构建立了一种双星型通信系统100，当然，在有两个交换卡时，其业务卡之间的数据传输带宽提升了两倍，提高了业务卡之间数据通道的可靠性。为了使得其传输带宽可以提升更大，还可以根据实际需求配置更多数量的交换卡，即交换卡可以为超过两个。在配置其他槽位的复用板卡120作为交换卡或业务卡时，只是复用板卡120启用或关闭的数据端口不同而已，由此，其可以根据实际需求灵活对复用板卡120进行配置。
在上述实现过程中，通过确定对应的槽位信息来对不同槽位的复用板卡120进行配置，使得可以根据需求配置相应槽位的复用板卡120为交换卡或业务卡。
另外，主控卡110在配置复用板卡120为交换卡或业务卡之前，在检测到有槽位插入板卡时，可以向各个板卡下发板卡的上电指令，以使得各个板卡接入电源进行工作，然后再向各个板卡发送信息获取请求，即请求获取各个板卡的相关信息。
可以理解地，复用板卡120中可以配置有管理单元，复用板卡120的管理单元在收到主控卡110发送的上电指令后，开启后级电路的供电系统，后级电路上电工作，进行板卡的上电加载和配置。
其中，主控卡110中配置有系统控制单元，该系统控制单元可以用于接收用户的通信系统100建立指令，如建立指令中包括需配置三个复用板卡120为业务卡，两个复用板卡120为交换卡，所以，主控卡110的系统控制单元可在接收到该建立指令后，监控FULL-MESH背板130中槽位的板卡插入情况，如在检测到FULL-MESH背板130中有5个槽位插入有板卡时，则向这5个槽位中的板卡发送信息获取请求，这5个槽位中的板卡接收到该信息获取请求后，可向主控卡110发送自己的板卡信息，板卡信息包括板卡型号或板卡能力，板卡能力包括是否支持交换卡和是否支持业务卡的能力属性，所以，主控卡110可基于板卡信息确定该板卡是否为复用板卡120。
也就是说，主控卡110可以根据复用板卡120所支持的工作模式来确定配置对应的复用板卡120工作在交换卡或业务卡，主控卡110若需配置1号和2号槽位的复用板卡120 为交换卡，则获取1号和2号槽位的复用板卡发送的板卡信息中其复用板卡所支持的工作模式，并根据其所支持的工作模式确定复用板卡是否支持作为交换卡进行工作，若是，则向复用板卡发送交换卡配置指令，此时该复用板卡可以仅支持交换卡模式，或者支持交换卡模式和业务卡模式；主控卡110若需配置3号、4号和5号槽位的复用板卡120为业务卡，则获取3号、4号和5号槽位的复用板卡发送的板卡信息中复用板卡所支持的工作模式，并根据其所支持的工作模式确定复用板卡是否支持作为业务卡进行工作，若是，则向复用板卡发送业务卡配置指令，此时该复用板卡仅支持业务卡模式，或者支持交换卡模式和业务卡模式。
当然，本公开实施例中，为了能够灵活配置对应数量的交换卡或业务卡，FULL-MESH背板130中各个槽位插入的板卡均为支持交换卡和业务卡的复用板卡120。
主控卡110向复用板卡120发送的配置指令用于指示复用板卡120具体工作在交换卡模式或者业务卡模式，即主控卡110向需要配置为交换卡的复用板卡发送的交换卡配置指令用于指示该复用板卡工作在交换卡模式，主控卡110向需要配置为业务卡的复用板卡发送的业务卡配置指令用于指示该复用板卡工作在业务卡模式。
由此，需要配置为交换卡的复用板卡在接收到主控卡110发送的交换卡配置指令后，根据该交换卡配置指令作为交换卡进行工作以及通过对应的连接通道建立交换卡之间的卡间数据通道以及与业务卡之间的卡间数据通道。
其中，需要配置为交换卡的复用板卡接收到交换卡配置指令后，其复用板卡中的管理单元按照交换卡模式进行加载，建立跨卡通道的映射配置等。例如，交换卡之间的卡间数据通道用于交换卡之间的数据转发，交换卡与业务卡之间的卡间数据通道用于交换卡与业务卡之间的数据传输，如图3中，4号槽位和5号槽位的复用板卡120配置为交换卡，其4号槽位中的PORT4端口与5号槽位中的PORT4端口连接，这两个端口之间的连接关系即为交换卡之间的卡间数据通道。所以，需要配置为交换卡的复用板卡在接收到交换卡配置指令后，检测其相互连接的端口，然后各自启用该相互连接的端口作为交换卡之间的连接端口，并记录下来，以此在进行业务数据转发时，可以通过查找对应的连接的端口，并通过该端口转发出去即可。
需要配置为业务卡的复用板卡在接收到主控卡110发送的业务卡配置指令后，根据该业务卡配置指令作为业务卡进行工作以及通过对应的连接通道建立与交换卡之间的卡间数据通道。
其中，需要配置为业务卡的复用板卡在接收到业务卡配置指令后，其复用板卡中的处理单元则按业务卡进行加载，完成业务卡的上行通道的配置，业务卡与交换卡之间的上行 通信通道用于业务卡之间的数据转发，如图3中，其1号、2号和3号槽位中的复用板卡120被配置为业务卡，其各个业务卡与交换卡通过槽位中的对应端口连接，如1号槽位的业务卡与4号槽位的交换卡通过1号槽位中的PORT2端口与4号槽位中的PORT2端口连接，这两个端口之间的连接关系即为业务卡与交换卡之间的上行通信通道。
由于业务卡配置指令中可以携带有交换卡所在的槽位信息，需要配置为业务卡的复用板卡在接收到业务卡配置指令后，基于交换卡所在的槽位信息检测其与交换卡相互连接的端口，然后启用该与交换卡相互连接的端口作为与交换卡之间的连接端口，并记录下来，以此在进行业务数据传输时，可以通过查找对应的连接的端口，并通过该端口传输出去即可。
需要说明的是，交换卡在接收到交换卡配置指令后，交换卡配置指令中可以携带有业务卡所在的槽位信息，所以交换卡可基于其业务卡所在的槽位信息检测其与业务卡之间的连接端口，从而启用对应的端口作为与业务卡之间的通信通道，并进行记录。
另外，由于FULL-MESH背板130上设置有多个端口，相应端口之间配置有对应的连接通道，业务卡之间也可以通过对应的连接通道进行连接，但是由于业务卡的业务数据由交换卡进行转发，若业务卡之间也可以直接传输数据，使得业务数据既通过交换卡转发，也通过业务卡直接发送，而使得两个业务卡之间的业务数据的传输通道形成环路。所以，为了避免传输通道形成环路，在所述业务卡之间的业务数据通过所述交换卡进行跨卡转发时，关闭所述业务卡之间的连接通道。例如，可以由主控卡110来控制业务卡之间的连接通道关闭，使得业务卡传输的业务数据通过交换卡进行转发，或者业务卡自身来控制业务卡之间的连接通道关闭；当然，若配置复用板卡120均为业务卡时，此时没有交换卡，则主控卡110也可以控制业务卡之间的连接通道开启，使得业务卡之间可以直接传输数据。
其中，主控卡110在控制其连接通道关闭或开启时，向对应的业务卡发送对应的指令，以指示业务卡关闭或开启业务卡之间的连接端口即可。
需要说明的是，若配置的复用板卡120中包括交换卡和业务卡，但根据需要若业务卡之间直接传输数据时，主控卡110也可以控制业务卡与交换卡之间的连接通道关闭，然后在需要交换卡参与数据转发时，控制业务卡与交换卡之间的连接通道开启即可。
在上述实现过程中，在通过交换卡进行业务数据的跨卡转发时，将业务卡之间的连接通道关闭，可使得业务卡之间的数据通过交换卡转发，提高了其数据传输效率。
作为一种示例，为了提高主控卡110的可靠性，主控卡110可以为两个，包括第一主控卡和第二主控卡，第一主控卡和第二主控卡可以通过协商确定主备关系，若第一主控卡为主用主控卡且第二主控卡为备用主控卡时，则第一主控卡用于对多个复用板卡120中每 个复用板卡120进行配置，第二主控卡用于在检测到第一主控卡出现故障时切换为主用主控卡。
例如，两个主控卡110在相互连接时，可以相互发送协商信息，以确定主备关系，如可以根据主控卡110的编号来确定主备关系，在两个主控卡110检测到连接时，第一主控卡可以向第二主控卡发送的协商信息中携带有第一主控卡的编号，如为1，第二主控卡也可以向第一主控卡发送的协商信息中携带有第二主控卡的编号，如为2，第一主控卡和第二主控卡可以相互发送信息来协商确定哪个编号的主控卡110为主用主控卡，另一个为备用主控卡。当然，两个主控卡110还可以根据用户的配置确定主备关系，如用户可以配置第一主控卡为主用主控卡，第二主控卡为备用主控卡。
主用主控卡用于对复用板卡120进行配置，此时备用主控卡不与复用板卡120进行通信，但是主用主控卡与备用主控卡之间的信息同步，即主用主控卡在对复用板卡120进行配置后，可将对应的配置信息发送给备用主控卡，由此，备用主控卡可知晓哪些复用板卡120配置为交换卡或业务卡。
在主用主控卡工作期间，备用主控卡可以实时监控主用主控卡的工作状况，在检测到主用主控卡出现故障时，自动切换为主用主控卡，与复用板卡120进行通信，从而可以继续对复用板卡120进行信息的下发以及信息的获取等工作，如获取各个复用板卡120当前的工作模式，确定其是否工作在对应的交换卡或业务卡模式等。
在上述实现过程中，采用两个主控卡110可有效提高通信系统100的可靠性。
