Description

POTN系统、POTN互通模块及报文互通方法 技术领域
本公开涉及通信技术领域，例如涉及一种分组光传送网(Packet Optical Transport Network，POTN)系统、POTN互通模块及报文互通方法。
背景技术
随着通信技术的不断发展，目前传输网络中的主要网络类型有以下几种：分组传送网(Packet Transport Network，PTN)、光传送网(Optical Transport Network，OTN)、基于同步数字体系(Synchronous Digital Hierarchy，SDH)的多业务传送平台(Multi-Service Transfer Platform，MSTP)。比如，传统的公共交换电话网络(Public Switched Telephone Network，PSTN)多为基于时分复用(Time Division Multiplexing，TDM)技术利用OTN接入传输的网络，也有以互联网协议(Internet Protocol，IP)业务为主的基于以太网技术接入PTN进行传输。这些通信技术及设备，满足着人们通话及上网等日常需求。
随着传输网络不断进化和融合，运营商需要将OTN和PTN进一步融合，POTN应运而生。然而，目前通过POTN设备进行互通存在以下较大限制：OTN接入设备只能和OTN设备进行互通，PTN接入设备只能和PTN设备进行互通。由于上述限制，要实现OTN业务和PTN业务互通，需要进行网络割接操作，对现有网络进行改造，耗费大量的人力和财力，在改造期间，还会影响到客户的使用。另外，通信网络的布点较多，全面改造将会是一项庞大的工程。

具体实施方式
以下结合附图对本申请的实施例进行详细说明，以下所说明的实施例仅用于说明和解释本申请，并不用于限定本申请。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在部分情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
在POTN系统中存在着PTN设备和OTN设备互通的需求，比如，以太网接入的网络电话(Voice over Internet Protocol，VOIP)终端与传统SDH接入的PSTN固话互通、以太网接入的第三代移动通信技术(3G)/第四代移动通信技术(4G)网络与传统SDH接入的PSTN互通，对于传输网的要求是需要实现PTN和OTN业务之间不同协议报文格式的转换互通。
图1为一实施例中通过POTN互联的网络架构示意图，如图1所示，3G无线网络(无线网络控制器(Radio Network Controller，RNC)1、RNC2、RNC3、RNC4等)通过接入/汇聚层的PTN设备接入或OTN设备接入，然后通过POTN设备进一步汇聚到骨干OTN，实现城域级业务传输和互通。然而，目前通过POTN设备进行互通存在以下较大限制：OTN接入设备只能和对端OTN设备进行互通(如图1中的实线所示，RNC1和RNC3互通)，PTN接入设备只能和对端PTN设备进行互通(如图1中的虚线所示，RNC2和RNC4互通)。
图2为一实施例中PTN终端和OTN终端实现对接的示意图。如图2所示，由于上述限制，要实现图2中RNC1(OTN业务)和RNC4(PTN业务)互通，需要进行网络割接操作，即，将RNC4从原有PTN网络割接到RNC3所在的OTN网络，利用图2中实线标识的OTN光传输通道进行互通。即使在同一个城 市内部的RNC3和RNC4互通，也需要通过上述网络割接操作进行改造，需要在新接入的网络设备中部署新的硬件单板。本实施例提供一种POTN系统、POTN互通模块及报文互通方法，能够在POTN系统内实现PTN终端与OTN终端的直接互通，以减少客户网络维护过程中的频繁改造、减少对传输网带宽及相关硬件资源的浪费，从而促进POTN网络的进一步融合和优化。
在一实施例中，POTN系统的网络结构和传输方式可以参照图3和图4。在图3和图4中，实线表示PTN业务数据流，虚线表示OTN业务数据流。
其中，PTN业务数据流所经过的路径可以为：POTN设备A的PTN业务板＝＝＞POTN设备A的交换系统＝＝＞POTN设备A的POTN汇聚板＝＝＞光传输网络＝＝＞POTN设备B的POTN汇聚板＝＝＞POTN设备B的交换系统＝＝＞POTN设备B的PTN业务板；或者，PTN业务数据流所经过的路径可以为：POTN设备B的PTN业务板＝＝＞POTN设备B的交换系统＝＝＞POTN设备B的POTN汇聚板＝＝＞光传输网络＝＝＞POTN设备A的POTN汇聚板＝＝＞POTN设备A的交换系统＝＝＞POTN设备A的PTN业务板。
其中，OTN业务数据流所经过的路径可以为：POTN设备A的OTN业务板＝＝＞POTN设备A的交换系统＝＝＞POTN设备A的POTN汇聚板＝＝＞光传输网络＝＝＞POTN设备B的POTN汇聚板＝＝＞POTN设备B的交换系统＝＝＞POTN设备B的OTN业务板；或者，OTN业务数据流所经过的路径可以为：POTN设备B的OTN业务板＝＝＞POTN设备B的交换系统＝＝＞POTN设备B的POTN汇聚板＝＝＞光传输网络＝＝＞POTN设备A的POTN汇聚板＝＝＞POTN设备A的交换系统＝＝＞POTN设备A的OTN业务板。
其中，POTN汇聚板仅起到汇聚PTN业务类和OTN业务类并进行传输的作用，无法实现PTN业务数据和OTN业务数据之间的交换功能。换言之，PTN业务数据流和OTN业务数据流无法在POTN设备内互通，只能在POTN设备(比如，POTN设备A)上将两种业务数据流汇聚到POTN汇聚板上传送到对端的POTN设备(比如，POTN设备B)。可见，当前POTN系统无法支持PTN业务的以太网报文格式与OTN业务的ODUk报文格式之间的直接映射功能。
如图5所示，本发明实施例提供一种POTN系统，包括：PTN模块510、OTN模块520以及POTN互通模块530；

在本实施方式中，成帧单元在转换得到相应的报文之后，可以将转换得到的报文转发给交换单元，由交换单元将该报文传输给交换系统。
在本实施方式中，交换单元设置为处理POTN系统内部的数据交互传输，实现信元与包交换技术；网络处理单元设置为负责对PTN业务的以太网报文进行处理及封装，比如，对以太网报文进行分类，然后对不同的分类以太网业务打标签及相关服务质量(Quality of Service，QoS)处理。

其中，POTN互通模块可以设置在POTN汇聚板上，或者，POTN互通模块可以为单独设置的单板，或者，POTN互通模块可以设置在交换系统单板上。关于POTN系统以及POTN互通模块的说明可以参照上述实施例的描述，故于此不再赘述。
本实施例中，在PTN模块和POTN互通模块分别进行PTN业务配置，以在PTN模块和POTN互通模块之间建立以太网报文的传输通路可以包括：在POTN互通模块上配置PTN业务映射信息、虚端口、隧道、伪线标签、以及以太网业务信息。
本实施例中，在OTN模块和POTN互通模块分别进行OTN业务配置，以在OTN模块和POTN互通模块之间建立ODUk报文的传输通路可以包括：在POTN互通模块上配置OTN业务映射信息、交叉连接参数。
在示例性实施方式中，以POTN系统应用在POTN设备为例，需要在POTN设备中提前部署POTN互通模块。即POTN设备上除了包含目前已有的PTN业务板、OTN业务板、POTN汇聚板，还需要新增POTN互通模块。其中，POTN互通模块可以部署在POTN汇聚板、或新增一种设置POTN互通模块的单板、或部署在交换系统单板上。
在本实施方式中，当网络维护过程中存在PTN终端与OTN终端的直接互通需求时，可以通过网络管理系统(以下简称网管，比如，设置于PC客户端)对POTN设备中的PTN业务板和POTN互通模块进行PTN相关业务配置，比如包括：业务映射配置、绑定虚端口、隧道伪线配置、以太网业务配置等；对OTN板卡和POTN互通模块进行OTN相关业务配置，比如包括：业务映射配置、交叉连接配置。
本发明实施例还提供一种报文互通方法，应用于POTN互通模块，包括：
POTN互通模块根据PTN业务配置信息，在所述POTN互通模块与PTN模块之间建立以太网报文的传输通路；
根据OTN业务配置信息，在所述POTN互通模块与OTN模块之间建立ODUk报文的传输通路；
执行以下至少一项：接收通过PTN模块接入的PTN业务的第一以太网报文，并将所述第一以太网报文转换为第一ODUk报文；接收通过OTN模块接入的OTN业务的第二ODUk报文，并将所述第二ODUk报文转换为第二以太网报文。
其中，PTN业务配置信息可以包括：PTN业务映射信息、虚端口、隧道、伪线标签、以及以太网业务信息。
其中，OTN业务配置信息可以包括：OTN业务映射信息、交叉连接参数。
下面参照图9对本实施例的报文互通方法进行举例说明。其中，根据实际需要，可以对每条需要实现报文互通的业务在POTN互通模块进行配置。在图9中，实线表示PTN业务数据流，虚线表示控制流程，点线表示OTN业务数据流。
如图9所示，POTN互通模块的控制单元可以通过以下方式配置PTN相关部分业务数据：
通过配置业务映射信息、虚端口，将本条业务使用的物理通道及速率带宽参数下发给POTN互通模块的成帧单元与网络处理单元；
通过配置隧道、伪线标签，将PTN业务以太网报文的转发标签参数及QoS等相关参数下发给网络处理单元；
通过配置以太网业务信息，将本条业务对应的PTN业务板(对应图9中的PTN模块)及相关接口参数下发给交换单元。
通过上述PTN相关部分业务数据配置将成帧单元、网络处理单元、交换单元连接打通，使得从PTN业务板发送过来的PTN业务数据包能够相继流经交换单元、网络处理单元以及成帧单元。其中，在成帧单元内部经过以太网处理子单元(ENET_SYS)的处理，到存储缓冲子单元(CPB)进行DCPB数据缓存，然后经OTN映射子单元(MAPOTN，Map to OTN)的通用成帧规程(GFP)映射对业务信号进行封装，再经ODUk交换子单元(ODUK SWITCH)进一步交换并发送ODUk报文，从而实现OTN网络支持的ODUk帧格式转换。
如图9所示，POTN互通模块的控制单元可以通过以下方式配置OTN相关部分业务数据：
通过配置OTN侧业务映射信息，将OTN侧带宽和时隙等参数下发给成帧 单元；
配置交换单元的ODUk交叉连接，交换单元可以将POTN互通模块的OTN数据包通过背板侧交换转给OTN业务板(对应图9中的OTN模块)。
通过上述OTN相关部分业务数据配置，在成帧单元内部的ODUk交换子单元中，将ODUk报文直接通过OTN侧的系统接口(SYS_INTERFACE)传递给交换单元，由交换单元以信元(cell)的形式将ODUk帧传递给OTN业务板，并在OTN业务板中提取出业务信号。
如图9所示，在完成上述PTN和OTN相关部分业务数据的配置过程后，业务信号在POTN互通模块的成帧单元便可完成PTN以太网报文与OTN ODUk帧格式的直接互通和转换。其中，PTN以太网报文到OTN ODUk帧格式经过的封装过程可以归结为：PTN以太网分组报文发向PTN侧的系统侧接口(SYSINTERFACE)后，经过以太网处理子单元(ENET_SYS)进行协议解析，然后报文在存储缓冲子单元(CPB)进行存储，并通知OTN映射子单元(MAPOTN)进行GFP封装以转换到OTN侧ODUKi帧格式，ODUk帧格式报文在ODUk交换子单元(ODUk SWITCH)进行交换并发送到OTN侧的系统侧接口(SYSINTERFACE)。因为上述的映射是双向的，对于图9中OTN侧的ODUk帧格式报文到PTN侧的以太网分组报文的映射方式原理相同，故于此不再赘述。至此，POTN互通模块即可完成PTN终端和OTN终端在POTN设备内互通的功能。
如图10所示，基于插入POTN互通模块后的POTN设备，RNC用户设备无论通过PTN设备或者OTN设备接入，经由POTN设备进行汇聚时均可以自由互通，即图10中RNC1和RNC4互通，或者RNC3和RCN4互通，均无需网络扩容或改造，仅需要修改POTN设备的配置即可直接互通。
实施例一
本实施例以同城内集团客户专线承载场景为例进行说明。
如图11所示，同一城市的一个集团的两个分公司(如分公司A和分公司B)需要运营商帮忙建设企业专网进行内部语音互通服务。其中，分公司A目前通过PSTN_A专网接入到OTN数据传输网络，分公司B通过RNC_B 3G无线网络接入到PTN数据传输网络。
实现传输层互通，不需要进行网络扩容和人工的网络割接操作，不用将分公司B所在专用3G网络RNC_B从PTN1传输设备切换到OTN1传输设备，可以实现和对端的分公司A所在的OTN1传输设备进行网络互通。
在本实施例中，仅需要客户通过远程操作，在电脑的网管上完成对POTN设备的配置即可，其中，实现业务互通原理及过程如下：分公司B所在专用3G网络RNC_B数据经过传输设备PTN1进入POTN设备后，通过网管配置POTN设备，将PTN业务板中的业务数据流通过背板侧的交换系统进入到POTN互通模块。
POTN互通模块的实现原理可以参照图9所示，业务报文到达POTN互通模块的交换单元，然后经过网络处理单元将业务信号传递给成帧单元，在成帧单元内部先后经过ENET_SYS子单元、CPB子单元、MAPOTN子单元，最终在ODUK Switch子单元中直接将业务信号转换为OTN网络支持的ODUk帧格式，使业务报文通过背板侧的OTN交换系统进入PSTN_A的OTN1设备，即完成图11中的PSTN_A和RNC_B对接。
可见，采用本实施例后，无需网络扩容及改造，仅需简易网管配置即可完成客户对接需求，降低了传输网络维护成本，提高了传输网络维护的灵活性，并降低某些城域内互通场景的传输时延。
实施例二
本实施例以跨城域网PTN与OTN互通应用场景为例进行说明。
如图12所示，在POTN传输的城域网络，一个集团的两个分公司(如分公司A和分公司B)分别位于不同城市，需要实现专网语音互通业务。分公司A在A城市通过PSTN_A专网接入到OTN1网络传输，分公司B在B城市通过RNC_B 3G无线网络接入到PTN1数据传输网络。
当前，要实现分公司A和分公司B的互通，则需分公司A业务数据经PSTN_A上传输后，经过接入层的OTN1+POTN1设备实现对业务数据的封装后利用光传输网络进行城域间传输。到达B城市的分公司B对接的POTN2设备后对业务数据进行解封装。因OTN1数据格式无法与PTN1数据格式直接互通，需要对现有网络POTN2和OTN2进行扩容和改造，将RNC_B的设备接入到OTN2的设备，才能将PSTN_A与RNCB之间通过PTN到OTN方式实现互通。
在本实施例中，业务数据同样经站点PSTN_A上送后，经过A城市所在接入的设备后通过光传输网络传输到B城市，经由B城市的POTN2设备时，仅需对POTN2设备上的POTN互通模块进行对接业务配置：POTN2设备将A城市OTN1设备传递过来的ODUK帧格式信号通过背板的OTN交换系统转发到PTON互通模块，然后POTN互通模块实现ODUk帧格式到以太网包(Packets)协议映射功能，转换成PTN设备支持的分组报文格式，从背板的交换系统将信号传递到PTN板卡后传递给PTN1设备。如此，通过POTN互通模块完成OTN与PTN协议报文格式映射，完成PTSN_A和RNC_B的直接对接。
在此过程中，仅需要客户远程操作，在电脑上的网管进行相应配置，即可实现业务互通，无需进行设备扩容及网络改造，极大地降低网络维护成本和提升了部署效率。
综上所述，本发明实施例解决了当前POTN系统没有支持PTN终端与OTN终端互通的功能，通过POTN互通模块实现了PTN业务的以太网报文格式与OTN业务ODUK报文格式之间的互通转换，促进了POTN系统和网络进一步融合互通，达到了不用现有网络进行改造即可实现PTN终端与OTN终端互通的效果，节省了现有网络割接操作对设备硬件资源、局点线程割接操作的投入，提高了通信网络业务传输的灵活性，并降低了部分城域内互通场景的传输时延。
此外，本发明实施例还提供一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令被处理器执行时实现上述报文互通方法。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序来指令相关硬件(例如处理器)完成，所述程序可以存储于计算机可读存储介质中，如只读存储器、磁盘或光盘等。在示例性实施方式中，上述实施例的全部或部分步骤也可以使用一个或多个集成电路来实现。相应地，上述实施例中的各模块/单元可以采用硬件的形式实现，例如通过集成电路来实现其相应功能，也可以采用软件功能模块的形式实现，例如通过处理器执行存储于存储器中的程序/指令来实现其相应功能。本申请不限制于任何特定形式的硬件和软件的结合。
