技术领域
本公开实施例涉及电子通信技术领域，尤其涉及一种固定带宽业务的承载方法、装置、电子设备及存储介质。
背景技术
城域传送网(Metropolitan Transmission Network，MTN)作为一种新型传送网技术体系，能够实现时分复用技术和分组交换的有效融合。MTN由城域传送网段层和城域传送网通路层构成。其中，城域传送网段层支持端口绑定，兼容以太网底层协议栈及标准以太网光模块；城域传送网通路层支持基于66B码块的时分复用交换，具备完善的端到端操作维护管理机制，支持任意Nx5G信道化客户信号的交叉复用。随着业务的发展，MTN也在发展更小颗粒度的时分复用通道，例如10Mbps颗粒度的通道。
然而，E1等类型固定带宽(Constant Bit Rate，CBR)业务是字节比特流编码，而MTN是基于和以太网底层一致的64/66B码块流，因此，CBR比特流无法直接填充至MTN通道中，此外，E1等类型CBR业务与MTN通道带宽存在差距，E1为2Mbps带宽，而MTN最小切片通道颗粒度为10Mbps，如果在一个MTN通道中承载多路CBR业务数据时，分别用不同的帧格式，则实现复杂，而且不同路数据的情况时延等性能不一致，承载效率较差。

具体实施方式
为了使本公开的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本公开进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。
下面将通过实施例并结合附图具体地对本公开的技术方案以及本公开的技术方案如何解决上述技术问题进行详细说明。下面的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。
另外，本公开实施例所记载的技术方案之间，在不冲突的情况下，可以任意组合。
本公开实施例提供了一种固定带宽业务的承载方法，通过固定带宽业务的承载装置实现，该承载装置可以是手机、平板电脑等电子设备，本公开实施例不作限定。图1为本公开实施例提供的一种固定带宽业务的承载方法的流程示意图。如图1所示，在本公开的实施例中，固定带宽业务的承载方法 主要包括以下步骤：
S101、在城域传送网通道中，传输承载固定带宽CBR业务、具有固定帧长的帧容器；
其中，帧容器包括S0码块、数据码块D码块和T码块，帧容器用于装载多路CBR业务数据，多路CBR业务数据按照固定字节长度交织映射至帧容器中放置业务净荷的区域。
在本公开的实施例中，承载装置可以在MTN通道中，传输承载CBR业务、具有固定帧长的帧容器，其中，MTN通道中传输的帧容器的数量可以为多个，例如，每间隔固定时长传输一个帧容器。具体的帧容器的数量，以及帧容器的固定帧长本公开实施例不作限定。
在本公开的实施例中，帧容器具有统一固定的帧结构。帧容器包括S0码块、数据码块D码块和T码块，帧容器中包括放置业务净荷的区域，放置业务净荷的区域至少包括以下其中区域中的一个：D码块中放置业务净荷的区域，T码块中放置业务净荷的区域。
需要说明的是，在本公开的实施例中，帧容器可以装载多路CBR业务数据，在一个帧容器中实际装载的CBR业务数据的数量可以根据实际需求和应用场景设定，例如，帧容器可以装载四路CBR业务数据，在实际应用中，一个帧容器可以实际装载三路CBR业务数据，另一个帧容器可以实际装载四路CBR业务，本公开实施例不作限定。
需要说明的是，在本公开的实施例中，多路CBR业务数据在装载到帧容器时，按照固定字节长度交织映射至帧容器中放置业务的区域。其中，固定字节长度可以为一个字节，即多路CBR业务数据是按照单字节交织映射至帧容器中放置业务净荷的区域。当然，固定字节长度还可以是其他字节长度，对于各个帧容器中多路CBR业务数据的交织映射所采用的字节长度是统一的，具体的固定字节长度本公开实施例不作限定。
图2为本公开实施例提供的一种示例性的帧容器示意图。如图2所示，四路CBR业务数据按照单字节交织映射，以第一路CBR业务数据E1#1填充1字节、第二路CBR业务数据E1#2填充1字节、第三路CBR业务数据E1#3填充1字节、第四路CBR业务数据E1#4填充1字节，依次交织填充在可以 放置业务净荷的区域。
在本公开的实施例中，帧容器中包含帧开销。如图2所示，帧容器由S0码块起始，然后依次是帧开销，放置业务净荷的区域和T码块，其中，T码块可以采用T7等具备数据填充区域的码块，T码块中放置业务净荷的区域属于整个帧容器中放置业务净荷的区域。
在本公开的实施例中，帧开销中携带容器空载指示；容器空载指示，用于指示帧容器是否装载多路CBR业务数据中各路CBR业务数据。
在本公开的实施例中，参见2所示，帧容器中可以用来装载四路CBR业务数据，帧开销中携带容器空载指示，用于指示帧容器是否实际装载了四路CBR业务数据。
在本公开的实施例中，容器空载指示为多个第一比特，一个第一比特指示帧容器是否装载多路CBR业务数据其中一路CBR业务数据；或者，容器空载指示为一个第二比特，帧容器中的第二比特与帧容器号联合指示是否装载一路CBR业务数据。
示例性的，在本公开的实施例中，帧容器可以装载四路CBR业务数据，帧开销中用不同的第一比特分别标识第一、第二、第三、第四路的CBR业务数据是否装载。例如，第一个第一比特为0时，表示放置业务净荷的区域内，用于装载第一路CBR业务数据的字节装载了第一路CBR业务数据，即帧容器装载了第一路CBR业务数据；第一个第一比特为1时，表示放置业务净荷的区域内，用于装载第一路CBR业务数据的字节未装载第一路CBR业务数据，即帧容器未装载第一路CBR业务数据。
示例性的，在本公开的实施例中，帧容器可以装载四路CBR业务数据，帧开销中用一个第二比特，通过与不同帧容器号联合指示四路CBR业务数据的装载情况。例如，帧容器号为1的帧开销中第二比特的值，表示放置业务净荷的区域内用于装载第一路CBR业务数据的字节是否装载了第一路CBR业务数据；帧容器号为2的帧开销中第二比特的值，表示放置业务净荷的区域内用于装载第二路CBR业务数据的字节是否装载了第二路CBR业务数据；帧容器号为3的帧开销中第二比特的值，表示放置业务净荷的区域内用于装载第三路CBR业务数据的字节是否装载了第三路CBR业务数据；帧容器号 为4的帧开销中第二比特的值，表示放置业务净荷的区域内用于装载第四路CBR业务数据的字节是否装载了第四路CBR业务数据。
需要说明的是，在本公开的实施例中，对于采用第二比特与帧容器号联合指示CBR业务数据的是否装载的方式，多路CBR业务数据其中一路CBR业务数据是否装载可以采用不同的帧容器号联合第二比特指示，例如，帧容器号1、5和9的帧开销中的第二比特都指示是否装载第一路CBR业务数据。
在本公开的实施例中，在帧容器中未装载第一路CBR业务数据的情况下，放置业务净荷的区域内，用于装载第一路CBR业务数据的字节填充有固定值；其中，第一路CBR业务数据为多路CBR业务数据中任一路CBR业务数据。
示例性的，在本公开的实施例中，帧容器可以装载四路CBR业务数据，当帧容器未装载第一、第二、第三、第四路的CBR业务数据其中一些路CBR业务数据时，可以在帧容器中放置业务净荷的区域内，用于装载但未装载其中一路CBR业务数据的字节填充固定值，例如这些字节均填充固定值1。
在本公开的实施例中，放置业务净荷的区域内，用于装载不同路CBR业务数据的字节中分别设置有负调整机会字节，用于适配业务数据流接收速率与容器发送速率之间的偏差。
示例性的，在本公开的实施例中，帧容器可以装载四路CBR业务数据，帧容器中放置业务净荷的区域内，用于分别装载第一、第二、第三、第四路CBR业务数据的字节中各自在固定位置设置有负调整机会字节，用于适配四路CBR业务数据的数据流接收速率与容器发送速率之间偏差。例如，参见图2，将用于分别装载第一、第二、第三、第四路CBR业务数据对应的字节中，各自的第一个字节设置为负调整机会字节，如果第一路CBR业务数据的数据流接收速率导致需要发送慢一些时，用于装载第一路CBR业务数据的字节中第一个字节，即负调整机会字节将不填充第一路CBR业务数据，可以填充其他值，例如，填充值0。
在本公开的实施例中，帧开销中携带负调整指示；负调整指示，用于指示帧容器的负调整机会字节是否装载CBR业务数据。
需要说明的是，在本公开的实施例中，放置业务净荷的区域内，用于装载不同路CBR业务数据的字节中分别设置有负调整机会字节，帧开销中携带 负调整字节使用指示，指示放置业务净荷的区域内，用于装载不同路CBR业务数据的字节中分别设置的负调整机会字节是否装载了CBR业务数据。
在本公开的实施例中，负调整指示为多个第三比特，一个第三比特，指示用于装载多路CBR业务数据其中一路CBR业务数据的字节中设置的负调整机会字节是否装载CBR业务数据；

示例性的，在本公开的实施例中，帧容器可以装载四路CBR业务数据，帧开销中用不同的第三比特分别指示用于装载第一、第二、第三、第四路的CBR业务数据的字节中设置的负调整机会字节是否装载CBR业务数据。例如，第一个第三比特指示用于装载第一路CBR业务数据的字节中设置的负调整机会字节是否装载CBR业务数据；第一个第三比特为0时，表示用于装载第一路CBR业务数据的字节中设置的负调整机会字节中装载了CBR业务数据，第一个第三比特为1时，表示用于装载第一路CBR业务数据的字节中设置的负调整机会字节中未装载CBR业务数据，此时，该负调整机会字节可填充固定值，例如，固定值0，也就是使用了该负调整机会字节适配了第一路CBR业务数据的业务数据流接收速率与容器发送速率之间的偏差。
示例性的，在本公开的实施例中，帧容器可以装载四路CBR业务数据，帧开销中用一个第四比特，通过与不同帧容器号联合指示放置业务净荷的区域中，用于装载各路CBR业务数据的字节中设置的负调整机会字节的使用情况。例如，帧容器号为1的帧开销中第四比特的值，指示用于装载第一路CBR业务数据的字节中设置的负调整机会字节是否装载CBR业务数据；帧容器号为2的帧开销中第四比特的值，指示用于装载第二路CBR业务数据的字节中设置的负调整机会字节是否装载CBR业务数据；帧容器号为3的帧开销中第四比特的值，指示用于装载第三路CBR业务数据的字节中设置的负调整机会字节是否装载CBR业务数据；帧容器号为4的帧开销中第四比特的值，指示用于装载第四路CBR业务数据的字节中设置的负调整机会字节是否装载CBR业务数据。
需要说明的是，在本公开的实施例中，对于采用第四比特与帧容器号联合指示负调整机会字节是否装载CBR业务数据的方式，用于装载多路CBR业务数据其中一路CBR业务数据的字节中设置的负调整机会字节是否装载CBR业务数据，可以采用不同的帧容器号联合第四比特指示，例如，帧容器号1、5和9的帧开销中的第四比特，都指示用于装载第一路CBR业务数据的字节中设置的负调整机会字节是否装载CBR业务数据。
在本公开的实施例中，帧开销中携带客户侧失效指示；客户侧失效指示，用于指示提供多路CBR业务数据中各路CBR业务数据的CBR客户侧端口的端口状态是否正常。
示例性的，在本公开的实施例中，帧容器可以装载四路CBR业务数据，在帧开销中携带客户侧失效指示，用于指示提供第一、第二、第三、第四路的CBR业务数据中各路CBR业务数据的CBR客户侧端口的端口状态是否正常。
在本公开的实施例中，客户侧失效指示为多个第五比特，一个第五比特指示提供多路CBR业务数据其中一路CBR业务数据的CBR客户侧端口的端口状态是否正常；
或者，客户侧失效指示为一个第六比特，帧容器中的第六比特与帧容器号，联合指示提供多路CBR业务数据其中一路CBR业务数据的CBR客户侧端口的端口状态是否正常。
需要说明的是，在本公开的实施例中，与上述容器空载指示和负调整指示类似，客户侧失效指示可以为多个第五比特或一个第六比特。
示例性的，表示4路E1业务的客户侧端口状态是否正常(例如该指示值为0时，客户侧端口状态正常；该指示值为1时，客户侧端口状态失效，该路E1净荷全置1)。通过这种方法，可以将发送端的E1客户信号的失效情况传递给对端。
示例性的，在本公开的实施例中，帧容器可以装载四路CBR业务数据，帧开销中用不同的第五比特，分别指示提供第一、第二、第三、第四路的CBR业务数据中各路CBR业务数据的CBR客户侧端口的端口状态是否正常。例如，第一个第五比特指示提供第一路CBR业务数据的CBR客户侧端口的端 口状态是否正常；第一个第五比特为0时，表示提供第一路CBR业务数据的CBR客户侧端口的端口状态正常，第一个第五比特为1时，表示提供第一路CBR业务数据的CBR客户侧端口的端口状态失效。
