Description

LCAS宿端删除成员的方法及实现该方法的宿端状态机 技术领域
本发明属于通信技术领域， 尤其涉及一种实现链路容量调整机制 ( LCAS , Link Capacity Adjustment Scheme )宿端删除成员的方法及 实现该方法的宿端状态机。 发明背景
国际电信联盟（ITU-T ) G.7042标准定义了 LCAS, LCAS提供了虚 级联组（VCG , Virtual Concatenation Group ) 的源端（Source Side )与 宿端 （Sink Side ) 的协商过程， 以保证在增加或删除成员时对业务不会 造成损伤,' 实现带宽的无缝调整。
虚级联（VC, Virtual Concatenation )的建立或删除、 成员的增加或 减少是通过改变控制分组（Control Packet ) 中状态字段的指令， 在源端 和宿端间建立协商通信进程来实现的。 LCAS所定义的控制分组描述了 虚级联的链路状态， 保证在网络发生变化时， 链路的源端与宿端能够保 持同步。 控制分组主要承载的控制字段有：
1. 成员状态（MST， Member status )字段： 从宿端发送至源端， 用 于传递各成员的状态；
2.再排序确认 ( RS-Ack, Re-sequence acknowledge )字段： 从宿端 发送至源端， 用于传递宿端检测出的成员的序列变化；
3.控制 （CTRL, Control )字段： 从源端发送至宿端， 用于实现两 端组成员状态同步；
4. 组标识（GID, Group ID )字段： 用于标识 VCG;
5. 差错校验码（CRC, Cyclic Redundancy Check )字段： 用于保护 控制分组。
对于虚级联组中的每个成员， 都有一个在源端的源端状态机， 和一 个在宿端的宿端状态机。 每个成员的源端状态机的状态包括： 空闲
( IDLE )状态、 正常 （NORMAL )状态、 路径失效（D J )状态、 增 加（ADD )状态和删除（REMOVE )状态。 每个成员的宿端状态机的状 态包括： 空闲（IDLE )状态、 用于表示该成员的信息未检测到错误或该 成员为新加入且请求通过的携载业务（ OK )状态， 以及用于表示该成员 的信息检测到有错误或该成员被删除的失败（FAIL )状态。
G7042标准中定义的源端状态机中， 为了保证业务无损伤， LCAS 要求增加或删除成员操作需要由源端发起， 具体实现过程可参见相关标 准， 由源端发起的增加或删除成员过程与本发明无关， 这里不再赘述； 而对于由宿端发起删除成员操作的情况， G.7042标准中定义的宿端状态 机无法保证对业务无损伤， 不能实现带宽的无缝调整。 商过程示意图， 如图 1所示， 宿端成员在携载业务状态即 OK状态下， 收到来自网管系统（ NMS , Network Management System )的删除成员指 示 MREMOVE后，宿端向源端发送该成员的 MST为 FAIL状态，可表示为： MST = FAIL, 接着停止从该成员内提取业务（ Stop reading payload ), 然 后该成员的状态迁移到 IDLE状态， 即被成功删除。
其中， NMS从宿端首先发起删除成员的操作时，宿端状态机的协商 过程具体如下：
1 )宿端收到来自 MS 的删除成员指示后， 向源端发送该成员的 MST为 FAIL状态；
2 )宿端在下一个复帧， 停止从该成员内提取业务， 并且将该成员 的状态迁移为 IDLE状态， 即该成员被删除。 需要说明的是， 图 1中与本发明相关的是虚线框中的删除成员状态 机部分， 其它部分与标准中规定的一致， 这里不再资述。
G.7042所定义的源端状态机相应的协商过程具体为：
1 ) 源端提取到该成员的 MST为 FAIL状态；
2 )将 CTRL字段的信息更改为 DNU状态， 即表示在源端已将该成 员的状态从 NORMAL状态迁移到 D U状态；
3 ) 源端在下一个复帧， 停止在该成员上映射业务 （Stop sending payload )。
上述协商过程中，按照标准宿端发送的该成员的 MST为 FAIL状态 需要经过 64ms/128ms后才能被源端 VCG提取到。假设宿端从发送该成 员的 MST为 FAIL状态到停止从该成员内提取业务的时间间隔为 tfe, 源端提取到 MST为 FAIL状态到该成员状态迁移到 DNU状态所需的时 间为 tTx, —旦源端停止映射业务的时刻和宿端停止提取业务的时刻不 同， 比如若 小于或大于 tTx+64ms/128ms, 便会造成对业务的损伤。 而 每个站点的 ^和 tTx均不同， 所以按照 G.7042的宿端状态机， 无法保证 从宿端首先发起删除成员时对业务无损伤， 不能实现带宽的无缝调整。 发明内容
为此， 本发明要解决的技术问题是提供一种实现 LCAS宿端删除成 员的方法， 能够保证由宿端发起的删除成员处理对业务无损伤。
本发明另一目的在于提供一种实现 ^述方法的宿端状态机， 能够保 证由宿端发起的删除成员处理对业务无损伤。
为达到上述目的， 本发明的技术方案具体是这样实现的：
一种实现链路容量调整方式 LCAS宿端删除成员的方法， 该方法包 括以下步驟： A. 宿端接收到删除成员指示后， 向源端通知待删除成员进入删除
REMOVE状态；
B. 宿端判断是否收到来自源端的通知响应， 若未接收到， 则所述待 删除成员继续处于删除 REMOVE状态且继续从所述待删除成员中提取 业务， 并等待； 若接收到， 则将该待删除成员的状态迁移为空闲 IDLE 状态。
步驟 A中所述通知待删除成员进入删除状态的方法为：
所述宿端向所述源端发送所述待删除成员的成员状态 MST字段信 息为失败 FAIL状态；所述宿端将所述待删除成员的状态由携载业务 OK 状态迁移为删除 REMOVE状态。
步骤 B中所述通知响应消息中携带有： 控制 CTRL字段的信息为路 径失效 DNU状态， 或增加 ADD状态， 或空闲 IDLE状态。
步骤 B中所述判定接收到通知响应之后 , 该方法还包括： 在下一复 帧停止从所述待删除成员中提取业务。
步驟 B中所述等待中， 该方法还包括： 若检测到所述待删除成员出 现故障， 则停止从所述待删除成员中提取业务， 之后结束本方法流程。
所述停止从所述待删除成员中提取业务之后，结束本方法流程之前， 该方法还包括： 所述宿端将所述待删除成员删除。
一种实现 LCAS宿端删除成员的方法的宿端状态机， 所述宿端状态 机的成员状态包括空闲 IDLE状态、携载业务 OK状态和失败 FAIL状态， 所述宿端状态机的成员状态还包括：
删除 REMOVE状态，在所述 REMOVE状态下，待删除成员等待来 自源端的确认删除的通知响应， 且继续从所述待删除成员中提取业务。
在所述 REMOVE状态下， 所述宿端收到来自源端的确认删除的通 知响应后， 在下一个复帧停止从所述待删除成员提取业务。 本发明在 G.7042所定义的 LCAS宿端状态机上，新增一个用于表示 处于删除过程中的状态即 REMOVE状态， 在 REMOVE状态下在宿端， 待删除成员正在等待删除确认， 且在 REMOVE状态下依然需要从该待 删除成员中提取业务； 在 REMOVE状态下该待删除成员收到源端发出 的相应的 CTRL字段的信息为 DNU状态后， 在下一个复帧停止从该待 删除成员提取业务， 并且将该待删除成员的状态迁移为 IDLE状态， 即 该待删除成员被删除。
在源端， 该待删除成员是在 CTRL字段的信息变为 DNU状态的下 一复帧停止在该待删除成员上映射业务； 而在宿端， 该待删除成员是在 收到 CTRL字段的信息为 DNU状态的下一复帧停止从该待删除成员内 提取业务， 这样保证了源端和宿端的带宽同时得到调整， 从而保证了对 业务无损伤。

为使本发明的目的、 技术方案更加清楚明白， 以下参照附图并举实 施例， 对本发明做进一步的详细说明。
图 2是本发明从宿端状态机发起删除成员的协商过程示意图， 假设 宿端成员在携载业务状态即 OK状态下， 收到来自 NMS或源端或其它 管理设备的删除成员指示删除成员指示 MREMOVE后， 该方法包括： 宿端 向源端通知待删除成员进入删除状态； 宿端判断是否收到来自源端的通 知响应， 若未接收到， 则继续处于删除状态且可以继续从该待删除成员 中提取业务， 并等待接收通知响应； 若接收到， 则将该待删除成员的状 态迁移为空闲状态。 协商过程具体包括如下步骤：
a)宿端向源端发送待删除成员的 MST为 FAIL状态， 以通知源端 更改该待删除成员的状态， 并且将该待删除成员的状态由 OK状态迁移 为 REMOVE状态；
b) 源端提取该待删除成员的 MST为 FAIL状态后， 将 CTRL字段 的信息更改为 DNU状态， 以使该待删除成员状态从 NORMAL状态迁 移为 DNU状态， 并将该 CTRL字段的信息为 DNU状态发送给宿端；
(c)宿端收到该待删除成员的 CTRL字段的信息为 DNU状态后，在 下一复帧停止从该待删除成员中提取业务;
(d)宿端将该待删除成员的状态从 REMOVE状态迁移为 IDLE状 态， 以示删除该待删除成员成功。
在源端， 该待删除成员是在 CTRL字段的信息变为 DNU状态的下 一复帧停止在该待删除成员上映射业务; 而在宿端， 该待删除成员是在 收到 CTRL字段的信息为 DNU状态的下一帧停止从该待删除成员内提 取业务， 这样保证了源端和宿端的带宽同时得到调整， 从而保证了对业 务无损伤。
需要说明的是， 图 2中与本发明相关的是虚线框中的删除成员状态 机部分， 其它部分与标准中规定的一致， 这里不再赘述。
进一步地， 在宿端等待源端返回通知响应期间， 如果宿端检测到该 待删除成员出现故障， 则立即停止从该待删除成员中提取业务， 同时将 该待删除成员从宿端删除； 或者， 该待删除成员在正常状态下， 根据源 端发送的 CTRL状态的信息决定是否删除成员， 比如， 若 CTRL字段的 信息为 DNU/ADD/IDLE状态， 则将该待删除成员删除。 以上所述仅为本发明的较佳实施例而已 , 并不用以限制本发明， 凡 在本发明的精神和原则之内， 所做的任何修改、 等同替换、 改进等， 均 应包含在本发明的保护范围之内。
