Description

一种基于嵌套管道的交叉连接统一描述方法 技术领域
本发明涉及 P-OTS (Packet- Optical Transport System, 分组 -光传 输系统）领域， 具体来讲是一种基于嵌套管道的交叉连接统一描述方 法。 背景技术
随着传输技术的发展， 各运营商传输网络中设备的种类越来越 多， 既有传统的 SDH ( Synchronous Digital Hierarchy, 同歩数字系列） /MSTP ( Multi-ServiceTransport Platform, 多业务传输平台） /WDM (Wavelength Division Multiplexing, 波分复用）设备， 又有逐渐推广 的 PTN(Packet Transport Network， 分组传输网）/OTN ( Optical Transmission Net,光传输网）设备，还有目前正在逐渐应用的 IPRAN (IP Radio Access Net, 综合承载与传送网络） 设备。
为了减少设备的数量和种类，开发同时支持 SDH/PTN/OTN统一 交换平台的 P-OTS设备有一定的迫切需求， P-OTS设备可以实现与 各类设备网络的接口，同时釆用波分技术在骨干网中进行大速率信号 传递。 但是在 P-OTS设备开发和管理中， 釆用现行的按照固定颗粒 逐级映射的方式， 有两个缺点：
一是容易造成带宽碎片。比如 OTN信号中，一个 ODU4 ( Optical channel Data Unit 4, 光通道数据单元 4) 固定的分解成可以解封装为 4个 ODU3， 每个 ODU3解封装为 4个 ODU2, 每个 ODU2解封装为 4个 ODU1， 每个 ODU1解封装为 2个 ODU0, 其他 SDH或者 PTN 的信号， 可以按照带宽颗粒封装到相应、 等速率的 OTN信号中。 这 种方式对于不逐级交叉的环境， 比如直接将多个 ODU0 和 ODU1/ODU2/ODU3在同一级进行交叉， 釆用顺序方式进行带宽分配 会产生信号颗粒碎片， 造成总带宽满足需求， 但是新的交叉连接无法 配置的情况， 减小了带宽的实际利用率。
二是对于 SDH、 OTN, PTN需要釆用不同的描述方法，比如 SDH 是 VC4， VC3， VC12三级描述； OTN釆用 ODUK(K=0, 1,2,3, 4,flex) 描述； 而 PTN釆用隧道、 伪线、 业务层进行描述； 对于异构网络管 理描述不统一， 造成操作用户难于理解和操作。 发明内容
针对现有技术中存在的缺陷，本发明的目的在于提供一种基于嵌 套管道的交叉连接统一描述方法， 实现在 P-OTS设备中将各种传输 信号的带宽颗粒进行交叉连接， 避免了带宽碎片的产生， 同时实现实 现 SDH/PTN/OTN的动态多级的交叉连接统一信号描述，便于操作用 户理解和操作。
为达到以上目的， 本发明釆取的技术方案是： 一种基于嵌套管道 的交叉连接统一描述方法， 包括如下歩骤： S1.根据传输网络国际标 准中定义的信号层次、 网络管理需要支持的信号颗粒类型， 制定逻辑 管道层次编号列表， 定义对应管道颗粒的层次编号； S2.分组光传输 系统中每个网元都包含的支路侧和线路侧，根据各自的客户侧信号类 型和背板侧承载通道信号类型，在满足不同传输系统国际标准中信号 封装映射的全部路径条件下， 分别确定支路侧和线路侧中， 客户侧管 道和背板侧承载通道管道之间的封装映射路径、总封装映射层级； S3. 根据所述封装路径确定封装映射路径每级路径管道的封装属性描述； S4.根据每级路径管道的封装属性描述， 形成多级信号管道封装映射 描述； S5.釆用支路侧信号多级管道封装映射描述作为源信号， 线路 侧信号多级管道封装映射描述作为宿信号，形成网元内基于嵌套管道 的交叉连接的统一描述。
在上述技术方案的基础上， 所述 S1中， 层次编号釆用 3位自然 数分段方式， 每段网络数字定义一种网络类型， 层次编号首位数字区 分传输设备信号的网络类型。
在上述技术方案的基础上， 所述 S1中， 每段网络数字都预留部 分数值空间， 用于对新的信号类型的扩展。
在上述技术方案的基础上， 所述 S2的具体歩骤如下， S21.根据 客户侧接口类型和背板侧承载通道接口的带宽颗粒的层次信息，操作 网管的用户确定封装路径策略； S22.根据客户侧接口最大带宽颗粒层 次信息、背板侧承载接口最大带宽颗粒层次信息、以及封装路径策略， 列出全部封装映射路径； S23.在全部封装映射路径中， 确定操作网管 的用户需要使用的封装映射路径； S24.根据需要使用的封装映射路 径，确定从客户侧接口信号到背板侧承载通道接口信号中间经过的总 封装映射层级。
在上述技术方案的基础上，所述封装映射路径涵盖小颗粒信号封 装入各层大颗粒信号的整个封装路径，不同传输网络信号遵循各自信 号封装结构的国际标准。
在上述技术方案的基础上， 所述 S3中， 每级路径管道的封装属 性描述由封装层次和管道号两部分组成。
在上述技术方案的基础上，所述封装层次从所述逻辑管道层次编 号列表中具体的管道信号颗粒选取，每个管道的管道号是该管道在上 层父管道中的编号。
在上述技术方案的基础上， 所述 S4中， 信号的描述包含封装映 射管道层级数和具体的各层描述属性组合， 自顶向下每层都是上层业 务的子管道。
在上述技术方案的基础上， 所述统一描述包括源电路板、源物理 口、 源逻辑管道， 以及宿电路板、 宿物理口、 宿逻辑管道。
本发明的有益效果在于： 釆用多级嵌套的管道编号方式， 支持
SDH/MSTP/ASON/PTN/OTN/IPRAN/P-OTS 等各种传输网络设备交 叉连接的统一描述方法， 大大提高交叉连接描述模型的通用性， 增强 网管系统交叉连接描述的可扩展性，便于实现跨越多种网络设备混合 组网的端到端业务配置中交叉连接的统一描述， 避免产生带宽碎片， 加强了带宽的实际利用率。 附图说明

为了逻辑管道层次编号列表随着新的网络系统标准出现新的信 号类型后可以扩展， 每段网络数字都预留部分数值空间， gP， 表 1中 每个编号范围中只给出了一部分的数字编号，其余的未用数字为将来 的扩展保留。
S2.分组光传输系统中每个网元都包含的支路侧和线路侧， 根据 客户侧信号类型、 以及支路侧和线路侧各自背板侧承载通道信号类 型， 在满足不同传输系统国际标准中信号封装映射的全部路径条件 下， 分别确定支路侧和线路侧中， 客户侧管道和背板侧承载通道管道 之间的封装映射路径、 总封装映射层级。
所述客户侧就是分组光传输系统中的对用户侧接口，承载通道就 是用来承载上层子业务的下层通道， 支路侧用来和网络外部相连， 线 路侧和网络内部相连，支路侧和线路侧一般分别由两块不同的电路板 来实现， 每块电路板都有客户侧和背板侧承载通道。
如图 2所示， 所述 S2的详细歩骤流程如下：
521.根据客户侧接口类型和背板侧承载通道接口的带宽颗粒的 层次信息， 操作网管的用户确定封装路径策略， 这部分由用户开通业 务的用途确定。
522.根据客户侧接口最大带宽颗粒层次信息、 背板侧接口最大带 宽颗粒层次信息、 以及封装路径策略， 列出全部封装映射路径。其中 封装映射路径策略根据各种传输系统信号封装映射的国际标准以及 S21中内容确定。封装映射路径涵盖小颗粒信号封装入各层大颗粒信 号的整个封装路径，不同传输网络信号遵循各自信号封装结构的国际 标准。 523.在全部封装映射路径中， 确定操作网管的用户需要使用的封 装映射路径。
524.根据所述使用的封装映射路径， 确定从客户侧接口信号到背 板侧承载通道接口信号中间经过的总封装映射层级。
在歩骤 S21至 S24中，可以先确定出支路侧电路板信号的总封装 映射层级， 再次使用同样的方法， 确定线路侧电路板信号的总封装映 射层级。 其中， 网络信号类型的不同， 参循的标准也不同， 参照各自 的国际标准， SDH釆用 SDH封装标准路径， 如国际电信联盟 G832 标准； PTN釆用 PTN分组传送的封装层次，如国际电信联盟 G.8110.1 标准； OTN釆用 OTN信号封装标准路径， 如国际电信联盟 G709标 准。 网管系统管理中， 对标准中的层次结合网管系统实际管理情况进 行了简化。
如图 3所示，本发明实施例中一个 10G以太网信号封装到 ODU4 承载信号的封装映射路径示意图。 在一个客户侧为 10G 以太网颗粒 的信号通过 ODU4颗粒通道承载 OTN路径中， 全部封装映射路径为 Ll、 L2、 L3、 L4、 L5， 每个信号层次可以作为一级管道， 其中 L1 为需要使用的封装映射路径， 其封装映射管道层级为 4。
53.根据所述封装映射路径确定所有信号每级路径管道的封装属 性描述，每级路径管道的封装属性描述由封装层次和管道号两部分组 成， 如图 4所示， 其中封装层次从所述逻辑管道层次编号列表（即表 1 ) 中具体的管道信号颗粒选取， 每级路径管道的管道号是该管道在 上层父管道中的编号。
54.根据每级路径管道的封装属性描述， 形成多级信号管道封装 映射描述。根据即表 1中的层次编号和具体管道号， 就可以形成交叉 信号的统一描述方式， 如图 5所示， 一个信号的映射路径可以涵盖多 层，所有信号的描述均包含封装映射管道层级数和具体的各层属性组 合， 自顶向下每层都是上层的子管道， 总层数为 n。
如图 6所示， 本发明实施例中管道生成的示意图。 利用歩骤 S4, 釆用 OTN网络信号为例， 将 1个 ODU4顶层管道封装了 2个 ODU2 和 1个 ODU3子管道，并且该层中 2号 ODU3管道又封装了 1个 ODU1 管道和其他管道， 结合表 1， 第 3 层 1 号管道信号可以描述为 005.1.004.2.002.1 ο
S5.如图 7所示， 釆用支路侧信号多级管道封装映射描述作为源 信号， 描述格式依次为源电路板、 源物理口、 源逻辑管道； 如图 8所 示， 釆用线路侧信号多级管道封装映射描述作为宿信号， 描述格式依 次为宿电路板、 宿物理口、宿逻辑管道； 二者形成网元内基于嵌套管 道的交叉连接的统一描述。
其中， 源逻辑管道就是歩骤 S4中的嵌套管道的描述， 如图 6中 第 3层 1号管道信号源逻辑管道可以描述为 005.1.004.2.002.1， 加上 源电路板和源物理口信息就描述了整个源信号信息。同理可以描述出 宿信号信息， 这样通过源信号和宿信号信息的组合， 再加上交叉的属 性信息， 就可以形成统一的交叉连接描述。
本发明不局限于上述实施方式，对于本技术领域的普通技术人员 来说， 在不脱离本发明原理的前提下， 还可以做出若干改进和润饰， 这些改进和润饰也视为本发明的保护范围之内。本说明书中未作详细 描述的内容属于本领域专业技术人员公知的现有技术。
