参阅图1，数据传输系统100包括：集中控制器101、本端通信装置102、对端通信装置104和若干转发面设备103。在本端通信装置102向对端通信装置104发送建立构建路径请求时，路径构建请求先到达集中控制器101，集中控制器101识别出这是请求建立快速传输路径的请求，根据所述路径构建请求，构建所述本端通信装置102和对端通信装置104之间至少第一、第二两条快速传输路径，需要说明的是路径构建请求可以是本端通信装置发给对端通信装置的IP包，IP包内有本端通信装置和对端通信装置的标识,集中控制器接收到IP包后，通过识别本端通信装置和对端通信装置的标识来构建快速传输路径。
需要说明的是,第一快速传输路径和第二快速传输路径可以是集中控制器向本端通信装置102发送的从本端通信装置102至对端通信装置104的两条不同的传输路径；也可以是集中控制器向对端信装置104发送的从对端通信装置104至本端通信装置102的两条不同的传输路径；从本端通信装置102至对端通信装置104的两条不同的传输路径和从对端通信装置104至本端通信装置102的两条不同的传输路径可以对应互相重叠相同也可以分开不同。另外，转发面设备103可以是物理的转发面设备也可以是虚拟的转发面设备,例如，虚拟交换机设备，而图中所示的两个或者多个虚拟的转发面设备103可在同一个物理的转发面设备中。
集中控制器101在构建好第一、第二两条快速传输路径之后，集中控制器101向本端通信装置102和对端通信装置104发送所述至少第一、第二两条快速传输路径。本端通信装置102接收到所述至少第一、第二
两条快速传输路径后，若本端通信装置102需要向对端通信装置104发送数据时，本端通信装置102通过第一、第二两条快速传输路径向另一端本端通信装置104传输相同内容，对端通信装置104通过第一、第二两条快速传输路径接收内容，这样即使某一个快速传输路径在传输过程中受到破坏或数据丢失，也可通过其他快速传输路径传输过来的数据进行处理，无需本端通信装置重新发送，这样保证了数据传输的可靠性和实时性。当然，在其它替代实施例中，集中控制器101在构建好第一、第二两条快速传输路径之后，仅向本端通信装置102和对端通信装置104中一个发送该第一、第二两条快速传输路径，当接收到该第一、第二两条快速传输路径的通信装置通过第一、第二两条快速传输路径向对端的通信装置发送数据包时，对端的通信装置根据数据包中携带的第一、第二两条快速传输路径回复数据包。
具体的，对端通信装置104在分别从所述第一、第二两条快速传输路径上接收第一数据包和第二数据包时，首先对第一数据包和第二数据包之中最早到达的数据包进行判断，判断是否是正确的数据包，如果正确则对此数据包进行处理，并丢弃第一数据包和第二数据包之中最晚接收到的数据包；如最早到达的数据包不正确则丢弃此数据包并向所述集中控制器和所述另一端通信装置发送数据错误信号，对第一数据包和第二数据包中最晚接收的数据包进行判断。通过对接收的数据进行判断，可使对端通信装置104避免重复处理，同时对最先接收且正确的数据包进行处理，保证了数据传输的实时性。
需要说明的是，本端通信装置102或对端通信装置104是下述本申请一种数据传输方法的第二实施方式和本申请一种通信装置的第一实施方式中的通信装置；对端通信装置104或本端通信装置102是下述本申请一种数据传输方法的第三实施方式和本申请一种通信装置的第二实施方式中的通信装置。
在本实施例中，通过构建至少第一、第二两条快速传输路径，本端通信装置和对端通信装置之间进行数据传输时，分别将所述第一、第二两快速传输路径添加至携带有相同内容的第一数据包和第二数据包中，
这样即使某一个快速传输路径在传输过程中受到破坏或传输的数据丢失，也可通过其他快速传输路径传输过来的数据进行处理，无需本端通信装置重新发送，这样保证了数据传输的正确性和实时性。
请参阅图2，图2是本申请一种数据传输方法的第一实施方式的流程图，数据传输方法包括：
步骤201：接收路径构建请求，其中，所述路径构建请求携带通信装置和另一端通信装置的标识；
通信装置和另一端通信装置是进行通信的两端，通信装置的标识是通信装置的标记，另一端通信装置的标识是另一端通信装置的标记，并且通信装置和另一端通信装置的标识均具有唯一性。标记可以为ID或者IP地址。值得说明的是，路径构建请求可以是通信装置发给另一端通信装置的IP包，IP包内有通信装置和另一端通信装置的标识,集中控制器接收到IP包后，通过识别通信装置和另一端通信装置的标识来构建快速传输路径。
步骤202：根据所述路径构建请求，构建所述通信装置和另一端通信装置之间至少第一、第二两条快速传输路径；
在通信装置和另一端通信装置之间有若干个转发面设备，因此，端到端的传输路径是不唯一的，在各个快速传输路径中除了通信装置和另一端通信装置之外其他转发面设备完全不相同，当然，在其他替代实施例中，各个快速传输路径中除了通信装置和另一端通信装置之外的其他转发面设备是可以部分相同的。因为集中控制器中的集中路由表记载了各个转发面的路由信息，所以构建快速传输路径是根据集中控制器中的集中路由表构建，需要说明的是：如果通信装置与另一端通信装置不在同一个域时，在构建快速传输路径时，是根据通信装置和另一端通信装置所在域的两个集中控制器的两个集中路由表构建的，其中构建的快速传输路径也是多条并且不相同的，当通信装置与另一端通信装置在同一个域时，直接该域上的集中控制器的集中路由表构建的。
进一步地，集中控制器构建的快速传输路径是多条的，在本实施例中用第一、第二快速传输路径仅仅是为了解释数据传输的实现方式，实
际上快速传输路径是构建了许多条，另外，第一快速传输路径和第二快速传输路径可以是集中控制器向通信装置发送的从通信装置至另一端通信装置的两条不同的传输路径；也可以是集中控制器向另一端信装置发送的从另一端通信装置至通信装置的两条不同的传输路径；从通信装置至另一端通信装置的两条不同的传输路径和从另一端通信装置至通信装置的两条不同的传输路径可以对应互相重叠相同也可以分开不同。
步骤203：向所述通信装置和另一端通信装置发送所述至少第一、第二两条快速传输路径，以使通信装置和另一端通信装置之间进行数据传输时，分别将所述第一、第二两快速传输路径添加至携带有相同内容的第一数据包和第二数据包中，并使网内的转发面设备根据第一数据包和第二数据包所携带的快速传输路径进行转发；
所述第一快速传输路径和第二快速传输路径为除通信装置和另一端通信装置之外其它节点完全不相同的路径，所以所述第一快速传输路径和第二快速传输路径是相互独立的，因此，第一数据包和第二数据包相互不受影响。
值得说明的是，本申请实施例中步骤201-203提供的数据传输方法的执行主体可以是集中控制器。
在本申请实施例中，通过构建至少第一、第二两条快速传输路径，通信装置和另一端通信装置之间进行数据传输时，分别将所述第一、第二两快速传输路径添加至携带有相同内容的第一数据包和第二数据包中，这样即使某一个快速传输路径在传输过程中受到破坏或传输的数据丢失，也可通过其他快速传输路径传输过来的数据进行处理，无需通信装置重新发送，这样保证了数据传输的正确性。
请参阅图3，图3是本申请一种数据传输方法的第二实施方式的流程图，数据传输方法包括：
步骤301：通信装置接收至少第一、第二两条快速传输路径，所述第一、第二两条快速传输路径均为通信装置至另一端通信装置的路径；
通信装置可以是发起路径构建请求的源端，也可以是与源端对应的对端，当通信装置是源端时，通信装置向集中控制器发送路径构建请求，
集中控制器根据集中路由表以及路径构建请求中的通信装置和另一端通信装置的标识进行构建快速传输路径，通信装置接收集中控制器发送的至少第一、第二两条快速传输路径；当通信装置是对端时，通信装置直接接收集中控制器发送的至少第一、第二两条快速传输路径；或者通信装置接收源端通信装置发送过来数据包，根据数据包中携带的第一、第二两条快速传输路径提取所述第一、第二两条快速传输路径并回复数据包。当然，在其他替代实施例中，路径构建请求也可以由源端和对端之外的其他设备发起的。又或者，路径构建请求为源端和对端之间传输的IP包，快速传输路径是根据源端和对端之间传输的IP包构建的。
步骤302：当所述通信装置向另一端通信装置发送待传数据时，所述通信装置根据待传数据，生成第一数据包和第二数据包，其中，所述第一数据包和第二数据包均携带相同的待传数据；
为了使另一端通信装置收到在第一数据包和第二数据包之后不会混淆，可以对各个数据包中待传数据进行封装编号，方便接收到进行筛选，例如：第一数据包里面待传数据的编号为A，如果第二数据包携带的待传数据相同的话，第二数据包里面待传数据副本的编号为A1。
步骤303：将所述第一快速传输路径添加至所述第一数据包中，以及，将所述第二快速传输路径添加至所述第二数据包；
通信装置和另一端通信装置之间网内的转发面设备根据第一数据包和第二数据包内的快速传输路径进行转发。
步骤304：分别发送携带有第一快速传输路径的第一数据包以及携带有第二快速传输路径的第二数据包，以使网内的转发面设备根据第一快速传输路径转发所述第一数据包，以及根据第二快速传输路径转发所述第二数据包；
由于快速传输路径是多条的，并且传输相同的数据，另一端通信装置接收到数据时，可以根据最先到达并且是正确的数据进行处理，使得在某一个传输路径中传输数据出现错误时，可以直接使用另一传输路径中的传输数据进行处理，非常方便。具体的，相同数据的处理方式请参阅图4，步骤302包括：
步骤3021：复制所述待传数据，生成所述待传数据的副本；
通信装置在传输数据之前，先将数据复制多份，并且可以对每一份数据进行标识，以使另一端通信装置不会混淆，例如：所述数据的编号可设置为A，副本的编号可以是A1、A2等等，当然，这些编号不会对数据内容造成任何影响，仅仅只是起了区分的作用。
步骤3022：将所述待传数据封装成第一数据包，将所述数据的副本封装成第二数据包；
根据预设的封装算法，对第一数据包和第二数据包进行封装，封装算法只是对数据封装格式不太相同而已，不会影响第一数据包和第二数据包所携带的内容。
进一步地，在传输过程中，通信装置和另一端通信装置之间网内的转发面设备可直接根据数据包内的快速传输路径进行转发，无需网内转发面设备在转发该数据包时均向集中控制器请求转发路由，大大减轻了集中控制器的负载，值得说明的是：因为数据是复制多份的，快速传输路径也是构建了多条，所以封装的数据包也是多个的，在这里只是用第一数据包和第二数据包的说法进行说明，是不作任何限制的。
值得说明的是，本申请实施例中步骤301-304提供的数据传输方法的执行主体可以是通信装置。
在本申请实施例中，通信装置将数据包和数据包副本通过至少第一、第二两条快速传输路径进行传输，这样即使某一个数据包在传输过程中受到破坏，另一端通信装置也可对其他数据包进行处理，保证了数据传输的正确性。
请参阅图5，图5为本申请一种数据传输方法的第三实施方式的流程图，数据传输方法包括：
步骤401：通信装置接收第一数据包和第二数据包中最早到达的数据包,其中，所述第一数据包是通过第一快速传输路径传输，所述第二数据包是通过第二快速传输路径传输，所述第一数据包和第二数据包携带相同的待传数据；
另一端通信装置向所述通信装置发送数据包时，分别通过至少第
一、第二两条快速传输路径传输内容相同的数据包，简而言之，一数据包分别通过至少第一、第二两条快速传输路径向所述通信装置发送两次，但是所述通信装置从至少第一、第二两条快速传输路径接收数据可以有先后顺序之分。
步骤402：所述通信装置判断所述第一数据包和第二数据包中最早到达的数据包是否是正确的数据包；
校验第一数据包和第二数据包是否正确的方式可以有多种，例如：在第一数据包和第二数据包中设置校验码，通过校验码校验第一数据包和第二数据包是否正确，或者，通过判断第一数据包和第二数据包是否包含首尾封装标识判断第一数据包和第二数据包是否正确。
步骤403：若正确，则对最早到达的数据包进行解析并获取数据内容；
对最早到达的数据包进行使用，无需等待其他数据包副本，这样节省了许多的时间，保证了数据传输的实时性，例如：汽车终端连接多个相邻的5g无线基站,因此从车联网平台到汽车终端存在多条传输路径,沿多条路径发送多个ip包副本，目的终端以最快的速度接收到正确的ip包,特别是在高速的小区切换时能保证高可靠的数据传输。
步骤404：丢弃所述第一数据包和第二数据包之中最晚接收到的数据包；
进一步地，如果最早接收的数据包不正确，则代表数据包中存在损坏的数据包，请参阅图6，数据传输方法还包括：
步骤405：若最早到达的数据包不正确，则丢弃所述最早接收到的数据包；
步骤406：判断所述第一数据包和第二数据包中最晚接收的数据包是否为正确的数据包；最早到达的数据包不正确的时候就接收第一数据包和第二数据包最晚接收到的数据包。
步骤407：若正确，则对所述最晚接收的数据包进行解析并获取数据内容；
步骤408：若不正确，则丢弃所述最晚接收的数据包并向所述集中
控制器和所述另一端通信装置发送数据错误信号；
若最晚接收的数据包都不正确，则说明在转发的过程中所有的快速传输路径都存在异常，向所述集中控制器和所述另一端通信装置发送数据包错误信号之后，集中控制器则对转发面设备进行检查，检查出异常转发面之后对快速传输路径进行重新构建，新的快速传输路径中不再包含异常的转发节点，构建好之后集中控制器再将新的快速传输路径发送至另一端通信装置和通信装置。
值得说明的是，本申请实施例中步骤401-408提供的数据传输方法的执行主体可以是通信装置。
在本申请实施例中，通信装置接收到另一端通信装置通过至少第一、第二两条快速传输路径发送过来的第一数据包和第二数据包，通过判断数据包的正确性，对最早接收且正确的数据包进行处理，这样保证了数据的正确性和实时性。

在本申请实施例中，通过构建若干条快速传输路径，通信装置将数据包和数据包副本通过这些快速传输路径进行传输，以使另一端通信装置根据收到的数据包之中到达最早的并且正确的传输数据进行处理，这样即使某一个数据包在传输过程中受到破坏，也可对其他数据包进行处理，无需通信装置重新发送，这样保证了数据传输的正确性和实时性。
