Description

主、 备用设备切换方法及装置
本申请要求于 2013 年 07 月 18 日提交中国专利局、 申请号为 201310300666. 4、 发明名称为 "一种主、 备用设备切换方法及装置" 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
本发明涉及通信技术领域, 尤其涉及一种主、 备用设备切换方法及装 置。 背景技术
当前, 网络发展日新月异, 随着网络的快速普及和应用的日益深入, 各 种增值业务在网络上得到了广泛部署, 网络带宽也以指数级增长, 网络短 时间的中断就可能影响大量业务, 造成重大损失。 作为业务承载主体的基 础网络,其可靠性也因此成为日益关注的焦点。虚拟路由冗余协议(Virtual Router Redundancy Protocol , VRRP) 就是这样一种可靠性技术, 可以实 现网络设备的冗余备份, 提升网络的可靠性。
在现实网络中使用 VRRP技术时, 如图 1所示, 通常 VRRP冗余组 110 包括的主用设备与接入设备 120之间可能会有一个或多个传输设备 130,而 VRRP冗余组 110只能感知与其自身直连的传输设备 130与其自身之间的链 路 (即图 1中的 A段链路) 是否出现故障, 从而切换主用、 备用设备。 当 其它段链路 (如图 1中的 B段链路) 出现故障时, 该 VRRP冗余组 110无法 感知, 即无法进行主用、 备用设备切换。

为了使本发明的目的、 技术方案和优点更加清楚, 下面将结合附图对 本发明作进一歩地详细描述, 显然, 所描述的实施例仅仅是本发明一部份 实施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术 人员在没有做出创造性劳动前提下所获得的所有其它实施例, 都属于本发 明保护的范围。
首先, 介绍本发明提供的一种主、 备用设备切换方法的应用场景。 如 图 2所示, 在该场景中, 具有路由功能的冗余组 210包括: 主用设备 211 和备用设备 212, 接入设备 220分别与主用设备 211和备用设备 212连接。 接入设备 220到主用设备 211之间包括至少一个传输设备 230, 接入设备 220到备用设备 212之间包括一个或多个串联的传输设备 230。接入设备 220 经一个或多个串联的传输设备 230及主用设备 211接入网络。 但是当接入 设备 220到主用设备 211之间的链路发生故障, 而无法利用主用设备 211 接入网络时, 具有路由功能的冗余组进行主用、 备用设备切换, 将主用设 备 211切换为备用设备, 将备用设备 212切换为主用设备, 以便接入设备 利用切换前的备用设备 212 接入网络。 其中, 具有路由功能的冗余组 210 具体为 VRRP冗余组, VRRP冗余组包括主用设备 211和备用设备 212。 接入 设备 220 具体为路由器、 交换机或数字用户线接入复接器 (Digital Subscriber Line Access Multiplexer, DSLAM) 等接入设备。 传输设备 230 具体为路由器、 交换机、 波分设备或包传输网络设备等传输设备。
下面以图 3为例详细说明本发明实施例提供的一种主、 备用设备切换 方法, 图 3 为本发明实施例提供的一种主、 备用设备切换的流程示意图。 该主、 备用设备切换方法应用于如图 1所示的场景中。 由图 1可知, 接入 设备与具有路由功能的冗余组包括的主用设备之间包括一个或多个串联的 传输设备, 具有路由功能的冗余组还包括备用设备。 其中, 具有路由功能 的冗余组具体为 VRRP冗余组, 接入设备具体为路由器、 交换机或数字用户 线接入复接器等。 传输设备具体为路由器、 交换机、 波分设备或包传输网 络设备等。
如图 3所示, 该主、 备用设备切换方法包括:
S301 , 在接入设备利用主用设备接入网络时, 检测主用设备上与传输 设备直连的接口, 以确定接入设备到主用设备之间的链路是否发生故障。
可选地, 检测通过主用设备的与传输设备直连的接口的业务流量在检 测周期内是否不大于预先设定的流量阈值; 若通过主用设备的与传输设备 直连的接口的业务流量在检测周期内大于预先设定的流量阈值, 则确定接 入设备到主用设备之间的链路未发生故障, 接入设备可以继续利用主用设 备接入网络, 不需要具有路由功能的冗余组进行主用、 备用设备切换。 若 通过主用设备的与传输设备直连的接口的业务流量在周期内不大于预先设 定的流量阈值, 则确定接入设备到主用设备之间的链路发生故障, 执行
S302。
比如参考图 2,接入设备 220经一个或多个传输设备 230与具有路由功 能的冗余组 210通信。 其中具有路由能的冗余组 210的主用设备 211通过 自身的接口 X与传输设备 230的接口 Y直连。 检测通过接口 X的业务流量 在检测周期内是否不大于预先设定的流量阈值; 若通过接口 X 的业务流量 在检测周期内大于预先设定的流量阈值, 则确定接入设备到主用设备之间 的链路未发生故障, 接入设备可以继续利用主用设备接入网络, 不需要具 有路由功能的冗余组进行主用、 备用设备切换。 若通过主用设备的接口 X 的业务流量在周期内不大于预先设定的流量阈值, 则确定接入设备到主用 设备之间的链路是否发生故障。
其中, 流量阈值可根据链路发生故障时, 业务流量的统计数据确定, 也可以直接将该流量阈值设置为 0。检测周期可以根据需要预设, 比如设置 为 100ms。
S302,当接入设备到主用设备之间的链路发生故障时,触发具有路由功 能的冗余组进行主用、 备用设备切换, 以使接入设备利用切换前的备用设 备接入网络。
在接入设备利用主用设备接入网络时, 在某一周期内检测到主用设备 的与传输设备直连的接口的业务流量在周期内不大于预先设定的流量阈 值, 则触发具有路由功能的冗余组进行主用、 备用设备切换, 将主用设备 切换为备用设备, 将备用设备切换为主用设备, 以使接入设备利用切换前 的备用设备接入网络, 从而保证在接入设备和切换前的主用设备之间的链 路发生故障时, 接入设备也能正常接入网络。
可选地, 图 3所示的方法, 可以由具有路由功能的冗余组来执行, 或 者由具有路由功能的冗余组包括的主用设备或备用设备来执行, 所述具有 路由功能的冗余组可以包括一个主用设备和一个或多个备用设备。 所述具 有路由功能的冗余组可以是 VRRP组, 组成该具有路由功能的冗余组的两个 设备之间运行 VRRP。
在一个具体的例子中, 如图 4所示, VRRP冗余组 410包括: 主用设备 411和备用设备 412, 接入设备 420分别与主用设备 411和备用设备 412连 接。接入设备 420到主用设备 411之间包括两个传输设备 431和 432, 接入 设备 420到备用设备 412之间包括一个传输设备 433。 传输设备 431、 432 和 433可以是交换机或其他包传输设备或波分设备。
在接入设备 420利用 VRRP冗余组 410的主用设备 411接入网络时,检 测通过主用设备 411上与传输设备 432直连的接口 X的业务流量在检测周 期内是否不大于预先设定的流量阈值。
若通过主用设备 41 1的接口 X的业务流量在检测周期内大于预先设定 的流量阈值, 则确定接入设备 420到主用设备 411之间的链路未发生故障, 接入设备 420可以继续利用主用设备接入 411网络,不需要 VRRP冗余组 410 进行主用、 备用设备切换。
若通过主用设备 41 1上的接口 X的业务流量在周期内不大于预先设定 的流量阈值, 则确定接入设备 420到主用设备 411之间的链路发生故障, 触发 VRRP冗余组 410进行主用、 备用设备切换, 将主用设备切换为备用设 备, 将备用设备切换为主用设备, 以使接入设备 420利用切换前的备用设 备 412接入网络, 从而保证在接入设备 420和切换前的主用设备 411之间 的链路发生故障时, 接入设备 420也能正常接入网络。
其中, 流量阈值可根据链路发生故障时, 业务流量的统计数据确定, 也可以直接将该流量阈值设置为 0。检测周期可以根据需要预设, 比如设置 为 100ms。
需要说明的是,本例中的 VRRP冗余组可以为任意具有路由功能的冗余 组, 接入设备 420可以为任意接入设备, 交换机 430可以为任意传输设备, 并且接入设备与主用设备或备用设备之间包括一个或多个串联的传输设 备。 对于上述不同场景下的主、 备用设备切换方法与本例相同, 在此不再 赘述。
利用本发明实施例提供的主、 备用设备切换方法, 通过检测具有路由 功能的冗余组中的主用设备的与传输设备直连的接口,确定接入设备与主 用设备之间的链路是否发生故障, 然后通知具有路由功能的冗余组进行主 用、 备用设备切换, 以使接入设备利用切换前的所述备用设备接入网络。 该方法不需要复杂的网络配置, 具有路由功能的冗余组便可获知两个传输 设备之间或传输设备与接入设备之间的链路故障, 从而实现主用、 备用设 备切换。
下面以图 5为例详细说明本发明实施例提供的一种主、 备用设备切换 装置, 图 5 为本发明实施例提供的一种主、 备用设备切换装置的结构图。 该主、 备用设备切换装置应用于如图 2所示的场景中的具有路由功能的冗 余组或者具有路由功能的冗余组包括的主用设备或备用设备。 由图 2可知, 接入设备与具有路由功能的冗余组包括的主用设备之间包括一个或多个串 联的传输设备, 具有路由功能的冗余组还包括备用设备。 其中, 具有路由 功能的冗余组具体为 VRRP冗余组, 接入设备可以具体为路由器、 交换机或 数字用户线接入复接器等, 传输设备具体为路由器、 交换机、 波分设备或 包传输网络设备等。 该主、 备用设备切换装置用于实现图 3所示的主、 备 用设备切换方法。

其中, 流量阈值可根据链路发生故障时, 业务流量的统计数据确定, 也可以直接将该流量阈值设置为 0。检测周期可以根据需要预设, 比如设置 为 100ms。
触发单元 520用于当接入设备到主用设备之间的链路发生故障时, 触 发具有路由功能的冗余组进行主用、 备用设备切换, 以使接入设备利用切 换前的备用设备接入网络。
在接入设备利用主用设备接入网络时, 检测单元 510在某一周期内检 测主用设备上与传输设备直连的接口的业务流量在周期内不大于预先设定 的流量阈值, 则由触发单元 520触发具有路由功能的冗余组进行主用、 备 用设备切换, 将主用设备切换为备用设备, 将备用设备切换为主用设备, 以使接入设备利用切换前的备用设备接入网络, 从而保证在接入设备和切 换前的主用设备之间的链路发生故障时, 接入设备也能正常接入网络。
利用本发明实施例提供的主、 备用设备切换装置, 通过检测主用设备 上与接入设备或传输设备直连的接口,确定接入设备与主用设备之间的链 路是否发生故障, 然后通知具有路由功能的冗余组进行主用、 备用设备切 换, 以使接入设备利用切换前的所述备用设备接入网络。 该方法不需要复 杂的网络配置, 具有路由功能的冗余组便可获知两个传输设备之间或传输 设备与接入设备之间的链路故障, 从而实现主用、 备用设备切换。
上述主、 备用切换装置还可以以另一种方式实现, 如图 6所示, 其为 本发明实施例提供的一种主、 备用设备切换装置的另一种结构示意图, 该 装置包括: 网络接口 610、 处理器 620和存储器 630。 系统总线 640用于连 接网络接口 610、 处理器 620和存储器 630。
