10GBASE-T的高速数据传输环境中, 当然对于 10/100/1000以太网也同样试用。 图 2是根据本发明实施例的以太网数据传输的流程图, 如图 2所示, 该流程包括 以下步骤 (步骤 S202-步骤 S214): 步骤 S202, 通过对以太网传输链路进行监测, 确认本端和对端相关的链路连接情 况。 以太网 10GBASE-T的本端和对端一般采用 4对非屏遮双绞线进行连接, 如图 3 所示的以太网数据传输链路的连接示意图, 图 3中的 4对非屏遮双绞线中的任意一对 或多对都可能出现损坏, 检测的方法不限, 例如可以采用信号回波的方式, 即如果发 出的信号, 没有回波则说明本链路断。 步骤 S204, 根据链路连接情况, 本端和对端进行相应的信息协商。 如果上述链路 连接情况为没有链路断裂,则执行步骤 S206,如果有 1条链路断裂,则执行步骤 S208, 如果有 2条链路断裂, 则执行步骤 S210, 如果有 3条链路断裂, 则执行步骤 S212, 如果有 4条链路断裂, 则执行步骤 S214。 例如采用图 3中的数据传输链路, 本端的 MAC下发信息到 PHY层, 再通过双绞 线传输到对端的 PHY层, 对端的 PHY层和对端 MAC层进行信息交换。 如果检测链路出现异常, 则利用剩余的正常连接的非屏遮双绞线,进行数据交互, 将链路信息通过本端发送给对端。 对端再将相关的信息, 以及需要降速和对应的降速 等级信息发送给本端。 步骤 S206, 没有链路断裂, 以正常的速率进行数据传输。 步骤 S208, 有 1条链路断裂, 本端和对端以 3/4的速率进行数据传输, 并发出故 告 ^ 步骤 S210, 有 2条链路断裂, 本端和对端以 1/2的速率进行数据传输, 并发出故 告 ^ 步骤 S212, 有 3条链路断裂, 本端和对端以 1/4的速率进行数据传输, 并发出故 告 ^ 步骤 S214, 有 4条链路断裂, 本端和对端停止数据传输, 并发出故障告警。 图 4是根据本发明实施例的以太网层次结构示意图, 如图 4所示, 以太网 MAC 层和 PHY层 (包括 PCS层和 PMA层) 的接口是 *GMI接口, 速率已固定, 如果是 XGMII则速率是 10G, 如果是 GMII则速率为 1G, PMA和 Medium的接口速率也是 固定, 为了达到降低速率的目的, 可以采用以下方法: 采取在 PCS层增加大的 FIFO 对数据进行缓存, 使 MAC控制下发数据的间隔, 并在 PCS层插入 IDLE码。 假设数 据传输码流为 M,插入的 IDLE码流为 N,则降低后的速率为(M-N) /Mx调整前速率。 如果速率为满速率则 N=0; 如果速率调整为原来速率的 3/4速率, 则 N=1/4M; 如果 速率调整为原来速率的 1/2,则 N=1/2M;如果速率调整为原来速率的 1/4,则 N=3/4M。 由于 GMI接口数据速率是固定的, 在一般情况下, 一个数据包被分配成 4等分, 当然可以选择平均分配的方式。在 4对双绞线正常传输时每对正常传输相同大小的包。 图 5是根据本发明实施例的以太网数据包的第一种映射关系示意图, 如图 5所示, 如 果所有的链路都正常, 将输入的 4 等分数据采用计数器的方式计数器在 1, 2, 3, 4 循环, 计数器为 1, 则在线路正常的第一路上传输; 计数器为 2, 则在线路正常的第二 路上传输; 计数器为 3, 则在线路正常的第 3路上传输; 计数器为 4, 则在线路正常的 第 4路上传输。 图 6是根据本发明实施例的以太网数据包的第二种映射关系示意图,如图 6所示, 如果其中有一条链路出现故障,将输入的 4等分数据采用计数器的方式计数器在 1, 2, 3循环, 计数器为 1, 则在线路正常的第一路上传输; 计数器为 2, 则在线路正常的第 二路上传输; 计数器为 3, 则在线路正常的第 3路上传输。 图 7是根据本发明实施例的以太网数据包的第三种映射关系示意图,如图 7所示, 如果其中有两条链路出现故障, 将输入的 4等分数据则采用计数器的方式计数器在 1, 2, 3, 4循环, 计数器为 1, 3, 则在线路正常的第一路上传输; 计数器为 2, 4则在线 路正常的第二路上传输。 图 8是根据本发明实施例的以太网数据包的第四种映射关系示意图,如图 8所示, 如果其中有三条链路出现故障, 将输入的 4等分数据都映射到唯一的正常的一路上传 输。 下面以 10GBASE-T 以太网数据传输为例对数据传输方法进行介绍, 在 10GBASE-T以太网数据传输中, VIP用户通过以太网访问存储在服务器中的重要视频。 数据传输的本端和对端同时对链路进行检测, 本实施例采用线上回波, 近端串扰和远 端串扰抵消检测的方法, 假设有两路非屏遮双绞线无回波则说明本双绞线链路断。 本端通过其它 3对正常非屏遮双绞线传输链路的检测结果给对端, 对端接受到本 端的链路检测结果后, 通过 MAC层, 进行降速为 3/4速率等级信号, 回传到本端, 本 端收到相关的结果。本端根据接受的链路检测结果,对本端以太网传输速率进行调整, 采用插入 IDEL码的方式,插入 1/2的 IDLE码,将本端和对端传输速率降为原来的 1/2, 则本端和对端以 1/2的速率传输, 并进一步对链路进行检测。 如果其中有两条链路出现故障, 则本端和对端以 1/2的速率传输, 并按照以太网 包映射关系图, 将输入的 4等分数据则采用计数器的方式计数器在 1, 2循环, 计数器 为 1, 则在线路正常的第一路上传输。计数器为 2, 则在线路正常的第二路上传输。 当 链路恢复时, 重新以满速率的方式进行传输, 从而提高数据传输的可靠性, 提升用户 体验。 对应于上述以太网数据传输速率的调整方法, 本实施例提供了一种以太网数据传 输速率的调整装置, 上述以太网数据传输速率的调整装置能够应用于以太网, 用于实 现上述实施例, 图 9是根据本发明实施例的以太网数据传输速率的调整装置的结构框 图, 如图 9所示, 该装置包括: 监测模块 10和调整模块 20。 下面对该结构进行具体 介绍。 监测模块 10, 设置为监测以太网中数据传输链路的连接情况; 调整模块 20,连接至监测模块 10,设置为根据上述监测模块监测的上述连接情况, 调整以太网中数据传输的速率。 通过上述装置, 监测模块 10对数据传输链路进行监测, 然后调整模块 20根据监 测的链路连接情况, 调整数据传输的速率, 解决了相关技术中由于以太网中数据传输 链路故障从而影响数据的稳定可靠传输的问题, 极大的提高了数据传输的稳定性和可 靠性, 提升了用户体验。 图 10是根据本发明实施例的以太网数据传输速率的调整装置的具体结构框图,如 图 10所示, 该装置除了包括上述图 9中的各个模块之外, 上述调整模块 20还包括: 协商单元 22, 设置为根据监测的上述连接情况, 对于上述速率的调整进行协商; 调整 单元 24,连接至协商单元 22, 设置为根据上述协商单元的协商结果调整以太网中数据 传输的上述速率。 监测数据传输链路的连接情况通过以下方式之一实现: 信号回波方式、 近端串扰 方式、 远端串扰方式。 在对数据传输链路的连接情况进行监测之后, 数据传输的本端 和对端进行以太网链路的情况交互, 本实施例提供了一种优选实施方式, 即上述协商 单元 22包括: 第一协商子单元, 设置为在监测到上述数据传输链路中有一条或多条链 路出现故障的情况下,协商确定降低以太网中数据传输的上述速率; 第二协商子单元, 设置为在监测到出现故障的上述一条或多条链路恢复的情况下, 协商确定提高以太网 中数据传输的上述速率。 在本端和对端进行协商之后, 根据协商结果调整速率, 即上述调整单元 24包括: 第一调整子单元, 设置为在协商确定降低上述速率的情况下, 在当前数据传输的码流 中插入 IDLE码流, 降低上述速率为 (上述数据传输的码流—上述 IDLE码流) /上述 数据传输的码流 X当前数据传输的速率;第二调整子单元,设置为在协商确定提高上述 速率的情况下, 在当前数据传输的码流中抽出上述 IDLE码流, 提高上述速率为满速 率。 在对数据传输的速率进行调整之后, 按照调整后的速率进行数据传输, 本实施例 提供了一种优选实施方式, 即上述装置还包括传输模块, 设置为按照上述调整模块调 整后的速率进行数据传输。 传输模块包括: 第一传输单元, 设置为在监测到上述一条 或多条链路出现故障的情况下, 将待传输的数据分配到剩余的正常链路上, 按照降低 后的速率进行数据传输; 第二传输单元, 设置为在监测到出现故障的上述一条或多条 链路恢复的情况下, 将待传输的数据分配到当前正常链路上, 按照提高后的速率进行 数据传输。 图 11是根据本发明实施例的以太网数据传输保护装置的结构示意图, 如图 11所 示, 该装置包括以太网检测模块, 以太网协商模块, 以太网速率动态调整模块。 以太网检测模块, 其功能与上述实施例中的监测模块的功能相当, 设置为对以太 网传输过程的链路进行检测, 确定相关的链路是否联通。 以太网协商模块, 其功能与上述实施例中的协商单元的功能相当, 设置为对以太 网本端和对端进行信息的交互, MAC层和 PHY层链路情况交互。 以太网速率动态调整模块, 其功能与上述实施例中的调整模块的功能相当, 设置 为根据以太网相关的链路的联通性, 动态调整以太网传输速率, 确保数据稳定可靠的 传输。 从以上的描述中可以看出, 本发明通过不断的对链路进行检测, 确定链路的连接 情况, 如果以太网内有某路信号线出现故障, 则本端和对端进行以太网链路的情况交 互, 采取降低数据传输速度的方式, 来保证数据的可靠传输, 如果以太网通路链路恢 复正常, 则重新以正常的速率传输, 从而极大提高了网络内数据传输的可靠性, 提升 了用户体验。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布在多个计算装置所 组成的网络上, 可选地, 它们可以用计算装置可执行的程序代码来实现, 从而, 可以 将它们存储在存储装置中由计算装置来执行, 并且在某些情况下, 可以以不同于此处 的顺序执行所示出或描述的步骤, 或者将它们分别制作成各个集成电路模块, 或者将 它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样, 本发明不限制于任 何特定的硬件和软件结合。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 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。
