下面结合具体的示例对本公开实施例的速率调整方法进行详细说明。在以下示例中,均以第一设备为发射端设备、第二设备为接收端设备为例进行说明。
示例一
图4a为本公开实施例的速率调整方法的交互流程示意图一;图4b为本公开实施例的速率调整方法中的第二层的处理示意图一;结合图4a和图4b所示,所述方法可包括:
在发射端,业务(service)以分组信号(或以太网信号)映射到第一容
器(例如ODUflex)。
示例性的,如图4a中左侧的时隙示意所示,速率调整前,映射到第一容器的工作时隙数量或工作比特数或工作块数为2个;在速率调整时,第一容器(例如ODUflex)的工作时隙数或工作比特数或工作块数发生变化,例如增加了一个工作时隙或工作比特数或工作块数。
将第一容器复用到或封装到第二容器(例如ODUkflex)。
示例性的,如图4a中左侧的时隙示意所示,速率调整前,复用到或封装到第二容器的工作时隙数量或工作比特数或工作块数为2个,空闲时隙或空闲比特数或空闲块数量为2个;在速率调整时,第二容器(例如ODUkflex)中的工作时隙数或工作比特数或工作块数发生变化,来承载第一容器的变化,例如将2个空闲时隙或空闲比特或空闲块中的1个空闲时隙或空闲比特或空闲块调整为工作时隙或工作比特数或工作块数。
第二容器(例如ODUkflex)复用到或封装到第三容器(或电层容器、段层容器,例如OTUflex)的净荷区,生成第三容器(例如OTUflex),增加电层容器开销(overhead)。
在第三容器,生成电层和光层间的接口信号(例如灵活光传送网接口(FlexO Interface,FOIC)或光传输通道(Optical Transport Lane,OTL)等),通过电层和光层之间的接口发送第三容器到光层。
本示例中,所述光层相当于前述实施例中的第一层;所述第一容器、第二容器和第三容器组成处理层相当于前述实施例中的第二层。
上述过程相当于前述实施例中第一设备的第二层的处理过程。
在光层,随着调整光层的调制格式,调整光层的净荷或载荷的比特率,从而使得光层和电层的速率同步,即电层去除空闲时隙、空闲比特或空闲块后的比特率与光层的净荷或载荷的比特率保持一致。
速率调整时,改变光层的调制格式和/或概率整形参数(概率整形参数例如可以是概率整形自由度、概率整形冗余度、概率整形输入比特数或比特率
等等),使得光层的净荷或载荷比特率变化。光层的净荷或载荷比特数(即有效传输比特数)与第二容器或第三容器中工作时隙的比特数同步;例如,通过概率整形,保持概率整形输出的波特率不变,同时使概率整形前的输入比特数与高阶容器中工作时隙的比特数同步,即概率整形后,传输的除去光层开销外的净荷或载荷的比特数与第二容器或第三容器中工作时隙的比特数同步。
光层的处理具体可参照图4b所示,第三容器到达光层,删除其中的空闲时隙,形成光层容器载荷或净荷(payload)。这时,光层的载荷或净荷比特率(即传输数据信息的比特率)与第二容器或第三容器中工作时隙的比特率同步。例如,通过概率整形,保持概率整形输出的波特率不变,同时使概率整形前的输入比特数与第二容器或第三容器中工作时隙的比特数同步,即概率整形后,传输的除去光层开销外的净荷或载荷的比特率与第二容器或第三容器中工作时隙的比特率(即去除空闲时隙或空闲比特或空闲块后的比特率)同步。
增加光层开销(overhead),形成光层帧(光层帧相当于前述实施例中的第一帧)。
上述过程相当于前述实施例中第一设备的第一层的处理过程。
对于接收端,接收端从发射端接收光层帧,对光层帧进行相当于上述第一设备的处理过程的逆过程。所述光层帧相当于前述实施例中第一设备发送给第二设备的第一帧,所述光层帧(或第一帧)中包括第二信息,所述第二信息用于指示第二参数,所述第二参数为所述第一设备(发送端)在第一层对所述第一帧进行处理时的参数,从而使得发射端和接收端的比特率保持一致。
具体可包括:接收端接收光层帧,解开光层帧,即去除光层容器开销(overhead);通过概率整形逆变化等处理,恢复出光层的净荷,进而恢复出包含工作时隙的第三容器(即不包含空闲时隙或空闲比特或空闲块的第三容
器);在该第三容器中添加空闲时隙或空闲比特或空闲块,得到第三容器;
生成光层和电层的接口信号,通过电层和光层之间的接口发送第三容器,将第三容器进行解封装得到第二容器,以及将所述第二容器解复用或解封装到第一容器,将所述第一容器解映射为业务。
其中,在速率调整时,可调整第二容器或第三容器的工作时隙数或工作比特数或工作块数。
示例二
图5a为本公开实施例的速率调整方法的交互流程示意图二;图5b为本公开实施例的速率调整方法中的第二层的处理示意图二;结合图5a和图5b所示,对于一般的光接口,如果存在上层(或第二层,例如,电层、数字层、MAC层、逻辑层等)和下层(或第一层,例如光层、物理层等)的划分,均可以采用本实施例的速率调整机制。在速率调整时,可以通过增加或减少空闲比特(无效比特、空闲时隙、空闲块等)来保持上层(或第二层)和下层(或第一层)之间的接口的符号率(波特率)不变。同时,在速率调整时,下层(或第一层)的净荷或载荷的比特率与上层(或第二层)去除空闲比特(无效比特、空闲时隙、空闲块等)后的比特率,在速率调整前后都保持一致。并且,发射端和接收端的比特率保持一致。这种接口机制,有望广泛的应用于OTN接口、以太接口、无源光纤网络(Passive Optical Network,PON)接口、无线光接口、空间光接口、无线接口等各种接口,实现小带宽和无损的带宽调整的接口要求。
具体的,方法可包括:
在发射端,业务(service)以分组信号(或以太网信号)映射到上层。这里,所述上层可相当于前述实施例中的第二层。
示例性的,如图5a中左侧的时隙示意所示,速率调整前,映射到上层的工作时隙数量或工作比特数或工作块数为2个,空闲时隙数量或空闲比特数或空闲块为2个;在速率调整时,上层的工作时隙数或工作比特数或工作块
数发生变化,例如将2个空闲时隙或空闲比特或空闲工作块中的1个空闲时隙或空闲比特或空闲块调整为工作时隙或工作比特或工作块。
形成上层帧或第二帧,即形成上层容器。例如可增加上层开销(overhead),形成上层帧或第二帧。
上述过程相当于前述实施例中第一设备的第二层的处理过程。
在下层或第一层,随着调整下层或第一层的调制格式和/或概率整形参数(如概率整形自由度、概率整形冗余度、概率整形输入比特数、概率整形输入比特率等等),调整下层的净荷或载荷的比特率,从而使得下层(或第一层)和上层(或第二层)的速率同步,即上层(或第二层)去除空闲时隙或空闲比特或空闲块后的比特率与下层的净荷的比特率保持一致。
速率调整时,改变下层(或第一层)的调制格式和/或概率整形参数(如概率整形自由度、概率整形冗余度、概率整形输入比特数、概率整形输入比特率等等),使得下层(或第一层)的净荷或载荷的比特率变化。下层(或第一层)的净荷或载荷的比特率(即传输数据信息的比特率)与第二帧中工作时隙或工作比特或工作块的比特率同步。例如,通过概率整形,保持概率整形输出的波特率不变,同时使概率整形前的输入比特数与上层容器(或第二帧)中工作时隙的比特数同步,即概率整形后,传输的除去下层开销外的净荷或载荷的比特率与上层容器(或第二帧)中工作时隙的比特率同步。
下层(或第一层)的处理具体可参照图5b所示,上层容器(或上层帧、第二帧)到达下层,删除其中的空闲时隙,形成下层容器或净荷载荷(payload)。这时,下层的净荷或载荷比特数(即有效传输比特数)与上层容器(或上层帧、第二帧)中工作时隙的比特数同步。例如,通过概率整形,保持概率整形输出的波特率不变,同时使概率整形前的输入比特数与上层容器中工作时隙的比特数同步,即概率整形后,传输的除去下层开销外的净荷或载荷的比特率与上层容器(或第二帧)中工作时隙的比特数(即去除空闲时隙后的比特数)同步。
增加下层开销(overhead),形成下层帧(或第一帧)。
上述过程相当于前述实施例中第一设备的第一层的处理过程。
对于接收端,接收端从发射端接收下层帧,对下层帧进行相当于上述第一设备的处理过程的逆过程。所述下层帧相当于前述实施例中第一设备发送给第二设备的第一帧,所述下层帧(或第一帧)中包括第二信息,所述第二信息用于指示第二参数,所述第二参数为所述第一设备(发送端)在第一层对所述第一帧进行处理时的参数,从而使得发射端和接收端的比特率保持一致。
具体可包括:接收端接收下层帧(或第一帧),解开下层帧,即去除下层容器开销(overhead);通过概率整形逆变化等处理,恢复出下层帧(或第一帧)的净荷,进而恢复出包含工作时隙的上层帧或上层容器或第二帧(即不包含空闲时隙或空闲比特或空闲块的上层帧或上层容器或第二帧);在该上层帧或上层容器或第二帧中添加空闲时隙或空闲比特或空闲块,得到上层帧或上层容器或第二帧。
生成下层和上层的接口信号,通过上层和下层之间的接口发送上层帧或上层容器或第二帧,将上层帧或上层容器或第二帧解映射为业务。
其中,在速率调整时,可调整上层容器(或上层帧或第二帧)的工作时隙数或工作比特数或工作块数。
