技术领域

具体实施方式
为了使本领域普通人员更好地理解本申请的技术方案，下面将结合附图，对本申请实施例中的技术方案进行清楚、完整地描述。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应所述理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致 的装置和方法的例子。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
(1)线卡(Line Card，LC)，是用于交换机、路由器或其他网络设备的访问线路与访问设备间的一种设备接口。
(2)源线卡，是指接收数据报文，并发送解析后的数据报文包含的待传输数据的线卡。
(3)目标线卡，是指接收源线卡发送待传输数据的线卡。
(4)交换网板，是用于将多个源线卡中的数据发送给对应的目标线卡。
在具体实践过程中，随着网络承载业务的不断发展，运营商和用户对网络的可靠性提出了越来越高的要求。作为重要的网络设备，路由器的高可用性对网络的可靠性起着决定性作用。交换网系统作为路由器的核心部分，主要负责完成网络数据报文的信息交换。
交换网系统主要包括源线卡、目标线卡和交换网板，其中源线卡通过交换网板向目标线卡发送数据报文。现有技术中存在通过调节源线卡与交换网板之间的带宽收敛比避免交换网板发生拥塞的情况，但是这样成本较高并且在进行数据报文传输过程中，若源线卡需要通过交换网板向目标线卡发送数据报文的数据量大于根据调高后的带宽收敛比可以发送的数据量，交换网板依然会出现拥塞的现象。另外还存在通过实时监控交换网板中传输的每条数据报文的数据量的时延避免交换网板发生拥塞的情况，但是由于时延检测具有滞后性，交换网板依然会出现拥塞的现象。
为此，本申请提供了一种调节交换网板拥塞的方法，通过源线卡发送包含待传输数据的数据量的信令申请给目标线卡，并根据目标线卡按照源线卡发送的信令申请的优先级确定的包含待传输数据量的信令响应后，按照待传输数据量，向目标线卡发送待传输数据，从而可以更准确的避免交换网板出现拥塞现象。
在介绍完本申请实施例的设计思想之后，下面对本申请实施例的技术方 案能够适用的应用场景做一些简单介绍，需要说明的是，以下介绍的应用场景仅用于说明本申请实施例而非限定。在具体实施时，可以根据实际需要灵活地应用本申请实施例提供的技术方案。
参考图1，其为本申请实施例提供的调节交换网板拥塞的方法的应用场景示意图。该应用场景包括线卡1、线卡2、线卡3、线卡4和交换网板，假设线卡1接收到数据报文，则线卡1作为源线卡，对接收到的数据报文进行解析，得到数据报文对应的目标线卡标识、数据报文的数据量、以及数据报文包含的待传输数据，假设根据目标线卡标识确定目标线卡为线卡3，则线卡1基于数据量生成第一信令请求，通过交换网板将第一信令请求发送给线卡3，线卡3基于第一信令请求的优先级生成至少包含第一待传输数据量的第一信令响应，并将第一信令响应发送给线卡1，使得线卡1根据第一待传输数据量，向线卡3发送待传输数据。
当然，本申请实施例提供的方法并不限用于图1所示的应用场景中，还可以用于其它可能的应用场景，本申请实施例并不进行限制。对于图1所示的应用场景的各个设备所能实现的功能将在后续的方法实施例中一并进行描述，在此先不过多赘述。
为进一步说明本申请实施例提供的技术方案，下面结合附图以及具体实施方式对此进行详细的说明。虽然本申请实施例提供了如下述实施例或附图所示的方法操作步骤，但基于常规或者无需创造性的劳动在所述方法中可以包括更多或者更少的操作步骤。在逻辑上不存在必要因果关系的步骤中，这些步骤的执行顺序不限于本申请实施例提供的执行顺序。
下面结合图1所示的应用场景，对本申请实施例提供的技术方案进行说明。
参考图2，本申请实施例提供一种调节交换网板拥塞的方法，包括以下步骤：
S201，对接收到的数据报文进行解析，得到数据报文对应的目标线卡标识、数据报文的数据量、以及数据报文包含的待传输数据。
如图3所示，假设线卡1、线卡2均为源线卡，线卡3为目标线卡，线卡1、线卡2均通过交换网板向线卡3发送数据，线卡1、线卡2和线卡3中均包括面板口1、面板口2、……、面板口n(n为正整数)，线卡1、线卡2和线卡3的带宽分别为各自对应的面板口1、面板口2、……、面板口n的带宽之和。例如，线卡1对应的面板口1、面板口2、……、面板口n的带宽均为10G，则线卡1的带宽为10nG。
当线卡1、线卡2接收到数据报文后，对数据报文进行解析，根据数据报文对应的目标线卡标识确定目标线卡均为线卡3。同时线卡1还可以根据解析结果得到数据报文的数据量是200G以及数据报文包含的待传输数据。线卡2还可以根据解析结果得到数据报文的数据量是100G以及数据报文包含的待传输数据。
S202，基于数据量生成第一信令请求，通过交换网板将第一信令请求发送给目标线卡标识对应的目标线卡，并接收目标线卡发送的第一信令响应；第一信令响应中至少包括目标线卡基于第一信令请求的优先级确定的第一待传输数据量。
示例性的，如图3所示，线卡1作为源线卡，还可以包含信令管理单元1，其中信令管理单元1包括目标线卡1对应的信令寄存器11、目标线卡2对应的信令寄存器12、…、目标线卡n对应的信令寄存器1n。同理，线卡2中还包含信令管理单元2，其中信令管理单元2包括目标线卡1对应的信令寄存器21、目标线卡2对应的信令寄存器22、…、目标线卡n对应的信令寄存器2n。
线卡3作为目标线卡，还可以包含调度管理单元1，其中调度管理单元1包括源线卡1对应的信令申请计数器1、源线卡2对应的信令申请计数器2、…、源线卡n对应的信令申请计数器n。
假设线卡1发送的第一信令请求中的数据量是200G，线卡2发送的第一信令请求中的数据量是100G，线卡3作为目标线卡，在接收到线卡1发送的包含200G数据量的第一信令请求和线卡2发送的包含100G数据量的第一信令请求之后，若确定线卡1的第一信令请求的优先级低于线卡2的第一信令 请求的优先级，则将线卡3可接收的200G数据量分配100G数据量给线卡1，并分配100G数据量给线卡2。也即线卡1的第一信令响应中至少包含100G的第一待传输数据量，线卡2的第一信令响应中至少包含100G的第一待传输数据量。因此线卡1和线卡2可以分别继续向线卡3发送多次第二信令请求，以便于将各自需要传输的100G的第一待传输数据量的数据发送给线卡3。
由于源线卡的信令管理单元中，每个目标线卡对应的信令寄存器中存在次数时，源线卡可以向对应的目标线卡发送第二信令申请，为了减少源线卡向对应的目标线卡发送数据的时延，可以对每个目标线卡对应的信令寄存器进行预设次数的分配。
具体的，源线卡中包括向目标线卡发送第二信令请求的预先分配次数，若源线卡通过交换网板向目标线卡发送第二信令请求，则减少预先分配次数；若源线卡通过交换网板接收目标线卡发送的第二信令响应，则增加预先分配次数；当预先分配次数小于或等于零时，丢弃源线卡中的待传输数据，以便于调节交换网板的拥塞。
按照上述示例继续说明，假设线卡1中的信令管理单元1中目标线卡1为线卡3，线卡3中的调度管理单元1中源线卡1为线卡1，那么线卡1向线卡3发送一次第二信令请求，信令寄存器11中的次数减一，线卡1接收一次线卡3发送的第二信令响应，信令寄存器11中的次数加一。线卡3接收一次线卡1发送的第二信令请求，信令申请计数器1中的次数加一，线卡3向线卡1发送一次第二信令响应，信令申请计数器1中的次数减一。
例如，对信令寄存器11预先分配次数是3次，当预先分配次数减少为0时，依然未接收到第二信令响应，则为了避免交换网板拥塞，将线卡1中的待传输数据丢弃。
S203，根据第一待传输数据量，向目标线卡发送待传输数据。
具体的，基于目标线卡的带宽、预设时间周期和第一待传输数据量，确定通过交换网板向目标线卡发送第二信令请求的次数和每次向目标线卡发送的第二待传输数据量，向目标线卡发送次数的第二信令请求，并在每次接收 到目标线卡发送的包含第二待传输数据量的第二信令响应之后，向目标线卡发送第二待传输数据量的数据，直至将待传输数据中第一待传输数据量的数据向目标线卡发送完成。
例如，将目标线卡的带宽乘以预设时间周期得到的积确定为每次向目标线卡发送的第二待传输数据量；将第一待传输数据量除以第二待传输数据量确定为向目标线卡发送第二信令请求的次数。
示例性的，目标线卡的带宽为400G，预设时间周期为10us，则每次向目标线卡发送的第二待传输数据量为400Gbit/s*10us＝4Mbit。若第一待传输数据量为100G，则向目标线卡发送第二信令请求的次数为100G/4Mbit＝25000次。
本申请的一实施例中，目标线卡包括多个不同优先级的目标端口时，在对接收到的数据报文进行解析，得到数据报文对应的目标线卡中目标端口标识、数据报文的数据量、以及数据报文包含的待传输数据。
如图4所示，假设图3中的线卡3包括目标端口31和目标端口32，并且目标端口31的优先级高于目标端口32的优先级，目标端口31又包括队列311和队列312，目标端口32又包括队列321和队列322，并且队列311的优先级高于队列312的优先级，队列321的优先级高于队列322的优先级。队列311、队列312、队列321和队列322分别包含调度管理单元，其中每个调度管理单元均包括源线卡1对应的信令申请计数器1、源线卡2对应的信令申请计数器2、…、源线卡n对应的信令申请计数器n(n为正整数)。
假设线卡1向线卡3发送的第一待传输数据量为300G，其中10G对应发送给队列311，290G对应发送给队列312，那么由于队列311的优先级高于队列312的优先级，则优先将发送给队列311的10G数据量发送完成。通过对目标线卡的进一步优先级设置，可以使得源线卡对数据报文解析后，更准确的向对应的目标端口传输数据，避免交换网板出现拥塞现象。
如图5所示，示出了本申请实施例提供的调节交换网板拥塞的系统中源线卡、交换网板和目标线卡之间交互的流程示意图，包括以下步骤：

S507，若源线卡通过交换网板向目标线卡发送第二信令请求，则减少预先分配次数；若源线卡通过交换网板接收目标线卡发送的第二信令响应，则增加预先分配次数；当预先分配次数小于或等于零时，丢弃源线卡中的待传输数据。
