一种实现分组微波数据流量整形的方法、 装置和系统
本申请要求于 2008 年 7 月 16 日提交中国专利局、 申请号为 200810029509.3、 发明名称为"一种实现分组微波数据流量整形的方法、 装置 和系统"的中国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及分组微波传输领域， 尤其涉及一种实现分组微波数据流量整形 的方法、 装置和系统。 背景技术
随着移动 3G、 NGN网络技术的演进以及业务模型向语音、 视频、 数据的 多媒体综合应用转型的发展， 网络向全 IP网演进发展， IP化分组业务的一个应 用特征就是业务突发、 流量不固定， 这样， 继续使用传统的基于固定传送带宽 的 PDH/SDH ( Plesiochronous Digital Hierarchy/Synchronous Digital Hierarchy, 准同步 /同步数字序列）微波已不能很好地满足网络 IP化应用的需求， 因此业 界提出了釆用分组传送技术的点到点固定微波系统， 通常称为分组微波。
分组微波除了使用 CAR ( Committed Access Rate , 承诺接入速率）、 CoS ( Class of Service, 业务分类）、 按优先级队列调度等分组处理技术， 使用端到 端连接管理如 MPLS、 PWE3等网络技术外， 还要求具备 AM ( Adaptive
Modulation, 自适应调制）技术， 支持 AM功能的分组 波可动态地调整空口 传送带宽， 当空口链路质量较好时（比如天晴的时候）， 设备可以釆用高调制 模式提供大带宽传送能力； 当空口链路质量恶化时（比如大雨， 大雾的时候）, 设备可以釆用低调制模式，提高链路的抗干扰能力，保证重要用户数据的传输 质量， 由此可以艮好地适应 IP化网络下分组业务突发、 流量动态变化的组网应 用需求， 既保障了实时性业务如 VOIP ( Voice Over IP , IP语音电话）、 Video业 务的稳定传送， 也可以充分利用空口带宽传送普通的背景类数据业务。
新一代的分组微波系统通常釆用了模块化设计方式， 比如， 现有的一个分 组微波系统实现方案使用了两级数据交换结构，其中的中央数据交换模块与多 个业务接口模块构建的接口单元连接， 完成整个系统的业务转发调度功能； 其 中的中频调制模块与数据交换模块结合构成微波中频接口单元，微波中频接口 单元中的数据交换模块一方面与中央数据交换模块连接，另一方面与中频调制 模块连接。
中央数据交换模块接收从各个接口单元发送的分组业务， 对业务按照优先 级类别进行分类处理后放入到相对应的优先级队列中，由输出调度器按照优先 级调度策略，将队列中来自各个业务接口单元的分组业务汇聚后输出到与微波 中频接口单元连接的接口中如 GE ( Gigabit Ethernet, 千兆以太网）接口。
微波中频接口单元中数据交换模块通过与中央数据交换模块连接的接口 如 GE接口接收分组业务， 根据业务的优先级进行分类后放入到对应的优先级 队列中，输出调度器按照优先级调度策略将队列中分组业务进行调度输出， 同 时还根据当前的微波空口带宽对输出的分组业务进行流量整形，比如当数据交 换模块输出流量超过空口带宽允许的发送速率时，所述数据交换模块根据优先 级调度策略对低优先级业务进行丟弃处理，以使传输的业务流量符合当前空口 带宽下业务速率的要求。流量整形后输出的分组业务在中频调制模块中经封装 处理、 复用成帧后再经中频调制处理由中频接口输出到微波单元发送到远端。 而中央数据交换模块在中频调制模块启用 AM功能改变调制模式期间不对输出 的分组业务进行流量整形处理。
但是本发明的发明人在实施本发明的技术方案时发现， 现有技术釆用分级 调度丟弃低优先级数据包的方式进行流量整形处理，这样进行的流量整形处理 效果较差。 发明内容

为使本发明的目的、技术方案和优点更加清楚， 下面将结合附图对本发明 作进一步地详细描述。
实施例一、 参照图 1 , 本发明实施例一的实现分组微波传输控制的系统包 括数据交换单元 1和中频调制单元 2。 中频调制单元 2, 用于根据微波空口传 送带宽和预先配置的最大传送单元数计算获得所述承 i若突发长度信息，并将包 括所述微波空口传送带宽和所述承诺突发长度信息的流量整形控制信息发送 至数据交换单元 1。 所述数据交换单元 1 , 用于接收所述中频调制单元 2发送 的流量整形控制信息，并根据所述流量整形控制信息对分组业务数据进行输出 流量整形处理。
结合图 1 ,数据交换单元 1具体包括第一接收单元 11 , 用于接收流量整形 控制信息，所述流量整形控制信息包括微波空口传送带宽信息和承 i若突发长度 信息， 所述承诺突发长度限定緩存的分组业务数据的最大数据量； 整形单元 12, 用于根据所述流量整形控制信息对分组业务数据进行输出流量整形处理。
中频调制单元 2具体包括计算单元 21 , 用于根据微波空口传送带宽和预 先配置的最大传送单元数计算获得所述承 i若突发长度信息。其中， 所述微波空 口传送带宽由中频调制单元 2的带宽获取单元获得，该获取单元为现有技术内 容， 在此不赘述。 第一发送单元 22 , 用于将包括所述微波空口传送带宽和所 述承诺突发长度信息的流量整形控制信息发送给数据交换单元 1。 緩存单元 23 , 用于緩存经所述数据交换单元 1流量整形处理后的分组业务数据。 第一判 断处理单元 24, 用于判断所述緩冲单元緩存的分组业务数据量是否达到预设 上限值， 判断为是时， 向数据交换单元 1发送暂停向所述緩存单元发送待緩存 的分组业务数据的信息。 第二判断处理单元 25 , 用于判断所述緩存单元緩存 的分组业务数据量是否达到预设下限值， 判断为是时， 通知数据交换单元 1 向所述緩存单元发送待緩存的分组业务数据。
具体实施时， 当微波空口链路质量改变时， 中频调制单元 2使用自适应调 制技术动态地调整微波空口传送带宽， 计算单元 21根据微波空口传送带宽和 预先配置的最大传送单元数 ( MTU , Maximum transport unit , 最大传送单元） 计算获得所述承诺突发长度信息。
所述承 i若突发长度信息的计算方法具体为：先计算出在当前空口传送带宽 下， 传送时间等于 1ms 时对应的发送数据字节数， 以该字节数作为计算出的 承诺突发长度值， 以承诺突发长度值作为承诺突发长度信息。承诺突发长度值 (字节） = (空口传送带宽 Mb/sx lms ) ÷8, 然后根据以下规则决定最终的承 i若突发长度值， 当计算出的承 i若突发长度值≤ ( 1 xMTU + nx64 ) 时， 取承 i若 突发长度值 = l xMTU + n <64 (字节）， 当计算出的 （l xMTU + nx64 ) <承 诺突发长度值 < 32000时，取当前计算出的承 i若突发长度值， 当计算出的承 i若 突发长度值≥ 32000时， 取承诺突发长度值 = 32000 (字节）。 其中， n为可以 设置的整数值， 一般建议 n = 6, 中频调制模块缺省 MTU参数值配置为 1522 字节， 当中频模块 MTU配置小于 1522字节时， 承 i若突发长度的计算值仍按 照缺省 1522 字节进行计算。 例如， 当空口传送带宽为 10Mb/s 时， 取 n=6,MTU=1522 字节， 根据承诺突发长度值 （字节） = (空口传送带宽 Mb/s lms ) ÷8得出承 i若突发长度为 1250, 小于 （ 1 x 1522 + 6x64 ) =1906, 则 最终承诺突发长度值为 1906。
当根据所述接收的微波空口传送带宽信息和预先配置的最大传送单元数 计算获得所述承诺突发长度信息后， 第一发送单元 22将包括所述微波空口传 送带宽和所述承诺突发长度信息的流量整形控制信息发送给数据交换单元 1 , 在具体实现过程中所述流量整形控制信息可以使用流量整形控制帧的形式发 送给数据交换单元 1。
数据交换单元 1的第一接收单元 11接收自中频调制单元 2发送的包括微 波空口传送带宽信息和承 i若突发长度信息的流量整形控制信息，其中承 i若突发 长度限定緩存的分组业务数据的最大数据量； 整形单元 12根据所述流量整形 控制信息对分组业务数据进行输出流量整形处理， 具体为整形单元 12根据所 述流量整形控制信息对分组业务数据进行输出流量整形处理，具体为根据所述 流量整形控制信息中的微波空口传送带宽信息调整数据交换单元 1 的输出速 率，根据所述流量整形控制信息中的承诺突发长度信息用于限定緩存的分组业 务数据的最大数据量； 在实施时， 当空口带宽小时， 需要设置承 i若突发长度值 小， 避免过多的长帧分组占据发送带宽， 使 CES ( Circuit emulation service, 电路仿真业务） 业务不能及时传送而产生额外的时延抖动， 从而导致 CES业 务端到端传送性能变差。当空口带宽大时，可适当设置承 i若突发长度值大一些， 在保证 CES业务传送性能时还可以尽可能多的传送数据类长帧业务。
此外， 中频调制单元 2中的緩存单元 23緩存经所述数据交换单元 1流量 整形处理后的分组业务数据，在进行分组业务数据緩存的同时， 第一判断处理 单元 24将判断所述緩冲单元 23緩存的分组业务数据量是否达到预设上限值， 判断为是时，向数据交换单元 1发送暂停向所述緩存单元发送待緩存的分组业 务数据的信息，数据交换单元 1接到所述暂停向所述緩存单元发送待緩存的分 组业务数据的信息后，停止向中频调制单元 2发送经流量整形处理后的分组业 务数据， 而緩存单元 23中的分组业务数据将继续通过中频调制单元 2调制成 中频信号输出。 随着緩存中的分组业务数据减少， 第二判断处理单元 25将判 断所述緩存单元 23緩存的分组业务数据量是否达到预设下限值，判断为是时， 通知数据交换单元 1向所述緩存单元 23发送待緩存的分组业务数据， 数据交 换单元 1接到所述通知后继续向中频调制单元 2发送经流量整形处理后的分组 业务数据。所述緩存单元 23上限值或緩存单元 23下限值根据当前微波空口传 送带宽进行设定。
具体实现中，所述中频调制单元还可用于对流量整形后输出的分组业务数 据进行经封装处理、 复用成帧后再经中频调制处理由中频接口输出。
实施例二、 参照图 2, 本发明实施例二实现分组微波传输控制的系统包括 数据交换单元 1、 中频调制单元 4及控制单元 3。 中频调制单元 4, 用于获得 微波空口传送带宽信息。 控制单元 3 , 用于接收所述中频调制单元发送的微波 空口传送带宽信息，根据所述接收的微波空口传送带宽信息和预先配置的最大 传送单元数计算获得所述承 i若突发长度信息，并发送包括所述接收的微波空口 传送带宽信息和所述计算的承诺突发长度信息的流量整形控制信息。数据交换 单元 1 , 用于接收所述中频调制单元发送的流量整形控制信息， 并根据所述流 量整形控制信息对分组业务数据进行输出流量整形处理。 另外， 中频调制单元 4, 还用于接收所述数据交换单元 1发送的进行流量整形处理后的分组业务数 据。
也就是说， 与本发明实施例一不同的是， 中频调制单元 4并不是使用流量 调整信息帧来通知数据交换单元 1修改输出流量参数；而是通过系统内部的控 制总线， 由中频调制单元将带宽调整信息（空口传送带宽）通知控制单元， 再 由控制单元根据实施例一中描述的计算方法计算得到相关的承诺突发长度值， 并写入到数据交换单元的输出端口配置参数中。
结合图 2,数据交换单元 1具体包括第一接收单元 11 , 用于接收流量整形 控制信息，所述流量整形控制信息包括微波空口传送带宽信息和承 i若突发长度 信息， 所述承诺突发长度限定緩存的分组业务数据的最大数据量。 整形单元 12, 用于根据所述流量整形控制信息对分组业务数据进行输出流量整形处理。 控制单元 3具体包括第二接收单元 31 , 用于接收中频调制单元发送的微 波空口传送带宽信息。 计算单元 32 , 用于根据所述第二接收单元 31接收的微 波空口传送带宽信息和预先配置的最大传送单元数计算获得所述承诺突发长 度信息。 第二发送单元 33 , 用于将包括所述接收单元接收的微波空口传送带 宽信息和所述计算单元计算的承诺突发长度信息的流量整形控制信息发送给 数据交换单元。
具体实施时， 当微波空口链路质量改变进行自适应调整时， 中频调制单元 4获得微波空口传送带宽信息并将所述通过控制总线发送给控制单元 3 , 控制 单元 3的第二接收单元 31通过控制总线接收中频调制单元 4发送的微波空口 传送带宽信息，计算单元 32根据所述第二接收单元 31接收的微波空口传送带 宽信息和预先配置的最大传送单元数计算获得所述承 i若突发长度信息。
所述承诺突发长度信息的计算规则具体为先计算出在当前空口传送带宽 下， 传送时间等于 1ms 时对应的发送数据字节数， 以该字节数作为计算出的 承诺突发长度值， 以承诺突发长度值作为承诺突发长度信息。承诺突发长度值 (字节） = (空口传送带宽 Mb/sx lms ) ÷8, 然后根据以下规则决定最终的承 诺突发长度值， 当计算出的承诺突发长度值≤ ( 1 xMTU + nx64 ), 取承诺突发 长度值 = l xMTU + n 64 (字节）， 当计算出的 （ l xMTU + n 64 ) <承诺突 发长度值 < 32000, 取当前计算出的承诺突发长度值， 当计算出的承诺突发长 度值≥ 32000, 取承 i若突发长度值 = 32000 (字节）。 其中， n为可以设置的整 数值， 一般建议 n = 6, 中频调制模块缺省 MTU参数值配置为 1522字节， 当 中频模块 MTU配置小于 1522字节时，承诺突发长度的计算值仍按照缺省 1522 字节进行计算。例如， 当空口传送带宽为 10Mb/s时，取 n=6,MTU=1522字节， 根据承诺突发长度值（字节） = (空口传送带宽 Mb/sx lms ) ÷8得出承诺突发 长度为 1250, 小于（ 1 x 1522 + 6x64 ) =1906, 则最终承 i若突发长度值为 1906。
当根据所述接收的微波空口传送带宽信息和预先配置的最大传送单元数 计算获得所述承诺突发长度信息后， 第二发送单元 33将包括所述微波空口传 送带宽和所述承诺突发长度信息的流量整形控制信息通过控制总线发送给数 据交换单元 1 , 数据交换单元 1的第一接收单元 11接收自控制单元 3发送的包括微波空 口传送带宽信息和承 i若突发长度信息的流量整形控制信息，其中承诺突发长度 限定緩存的分组业务数据的最大数据量； 整形单元 12根据所述流量整形控制 信息对分组业务数据进行输出流量整形处理，具体为根据所述流量整形控制信 息中的微波空口传送带宽信息调整数据交换单元 1的输出速率，根据所述流量 整形控制信息中的承 i若突发长度信息限制传输的分组业务数据的最大长度，以 限制连续输出的长帧分组的数量， 在实施时， 当空口带宽小时， 需要设置承诺 突发长度值小，避免过多的长帧分组占据发送带宽，使 CES ( Circuit emulation service, 电路仿真业务）业务不能及时传送而产生额外的时延抖动， 从而导致 CES业务端到端传送性能变差。 当空口带宽大时，可适当设置承 i若突发长度值 大一些，在保证 CES业务传送性能时还可以尽可能多的传送数据类长帧业务。
具体实现中，所述中频调制单元还可用于对流量整形后输出的分组业务数 据进行经封装处理、 复用成帧后再经中频调制处理由中频接口输出。

具体实施时根据所述流量整形控制信息中的微波空口传送带宽信息调整 数据交换单元输出速率，根据所述流量整形控制信息中的承 i若突发长度信息限 制传输的分组业务数据的最大长度， 以限制连续输出的长帧分组的数量，在实 施时， 当空口带宽小时， 需要设置业务突发长度参数值小， 避免过多的长帧分 组占据发送带宽， 使 CES ( Circuit emulation service, 电路仿真业务） 业务不 能及时传送而产生额外的时延抖动，从而导致 CES业务端到端传送性能变差。 当空口带宽大时， 可适当设置业务突发长度参数值大一些， 在保证 CES业务 传送性能时还可以尽可能多的传送数据类长帧业务。 其中， 所述承 i若突发长度信息可以由中频调制单元计算得到，也可以由控 制单元计算得到， 下面分别对这两种情况进行详细地描述。
