背景技术 随着网络的发展,如何更好的使数据在网络设备间进行高效传递成为一个 十分重要的问题。 流量工程( Traffic Engineering ,ΤΕ )是一种对流量进行测量、 建模、 描述和控制, 以达到预定性能目标的技术。 为了能够有效保障网络信道 的畅通, 流量工程需要进行大量配置。 虚拟专用网 ( Virtual Private Network, VPN )技术能够有效简化流量工程 的配置。 VPN具有虚拟和专用两个特征, 可以把现有的 IP网络分解成逻辑上 分离的网络。 VPN 的基本原理是利用隧道技术, 把所要发送的业务数据封装 在隧道中, 利用 VPN骨干网建立的专用数据传输通道, 实现数据的透明传输。 具体来说, VPN隧道一般指在 PSN ( Packet Switched Network )骨干网的 VPN 节点(一般为服务商边缘节点 PE )之间或 VPN节点与用户节点之间建立的用 来传输 VPN数据的虚拟连接。
使用 VPN选择隧道需要使用隧道策略。 VPN隧道策略之一是 VPN隧道 绑定方式, 即, 将某条隧道与特定的 VPN业务绑定, 该绑定的隧道为该业务 所独自占用。 VPN 隧道绑定策略是实现业务到专用隧道映射的技术, 但当多 个相同业务需要同时进行数据传输时, 由于所对应的隧道为同一条, 所以容易 造成此条隧道的堵塞, 而其他隧道却处于闲置状态,从而使得隧道的应用效率 较低。
发明内容
有鉴于此, 本发明的目的在于提供一种隧道配置方法及装置, 以实现隧道 的高效率应用, 技术方案如下:

所述连接链路生成模块, 用于控制所述 PE组中各 PE之间的连接路线, 生成多个连接链路;
所述隧道配置模块,用于使用与该业务相对应的隧道模版对所述多个连接 链路进行配置, 生成多个隧道。
本发明提供的一种隧道配置方法及装置, 可以根据不同业务选择相应的 PE组, 并根据与所述业务对应的隧道模板对 PE组之间的连接链路进行配置, 生成适合所述业务通信的多个隧道。 由于每一个业务都对应于多个隧道, 因此 当多个相同业务同时需要传输时,可以选择与之对应的多个隧道对多个相同业 务同时进行传输, 实现了隧道的高效率应用。

另外, 步骤 S101所生成的 PE组划分信息可以存储在各种存储设备中。
PE组划分信息可以进行实时或定时更新。
S102、 根据所述 PE组划分信息, 选择与被传输的业务相对应的 PE组; 本领域技术人员可以理解的是, 当有业务需要被传输时, 本发明根据该业 务便可以查找到与该业务相对应的 PE组。
S103、 控制所述 PE组中各 PE之间的连接路线, 生成多个连接链路; 本领域技术人员可知的是, 在获得 PE组划分信息以后, ***就可以直接 控制被传输的业务所对应的 PE组中各 PE之间进行连接,生成多个连接链路。 具体的, 可以向相同 PE组中的各 PE设备发送连接命令,控制这些 PE设备之 间进行连接。 连接的方式有多种, 如进行两两连接或当 PE间距离不大于预设 阈值时, 则进行连接。 当然, 也可以让各 PE获得 PE组划分信息, 然后控制 该业务所对应的 PE组中各 PE之间进行连接, 生成多个连接链路。 需要说明 的一点是, 隧道属于连接链路的一种。
对于让各 PE获得 PE组划分信息的方式,本领域技术人员可以理解的是, 各 PE对存储 PE组划分信息的存储设备进行数据访问便可以获得 PE组划分信 息。 当然, 也可以将存储设备中存储的 PE组划分信息发送到各 PE中, 使各 PE获得 PE组划分信息, 本发明在此不做限定。 具体的, PE组划分信息可以 通过内部网关协议 (IGP , Interior Gateway Protocols)发送到各 PE中。 内部网 关协议 IGP可以有多种,如: 中间***到中间***( IS-IS , Intermediate System to Intermediate System )路由协议和开放式最短路径优先( OSPE, Open Shortest Path First )协议。 当然, PE组划分信息也可以通过边界网关协议 (BGP, Border Gateway Protocol)或其他协议发送到各 PE中, 本发明在此不做限定。
需要说明的是, 在获得具体的 PE分组信息以及相对应的业务信息后, 处
于同一组的各 PE之间便可以进行连接, 生成连接链路。 具体的, 连接的方式 可以有多种, 如: 每一 PE与同一组的所有 PE之间进行连接, 即 PE组中各 PE进行两两连接, 生成连接链路; 或对于每一 PE, 判断同一组的其他 PE与 该 PE之间距离是否不大于预设值, 如果是, 则该 PE与距离不大于该预设值 的 PE之间进行连接, 生成连接链路, 否则不进行连接。
本领域技术人员可以理解的是, PE之间可以直接彼此进行连接, 生成连 接链路, 也可以通过服务商骨干设备 P进行连接, 生成连接链路。 当一 PE通 过不同的 P连接另一 PE时, 其生成的连接链路也是不同的。
S104、使用与该业务相对应的隧道模版对所述多个连接链路进行配置,生 成多个隧道;
需要说明的是,可以使用与该业务相对应的隧道模版对所述多个连接链路 的链路参数和 /或链路功能进行配置。 当然, 也可以对连接链路的其他属性进 行配置。 具体的, 链路参数可以包括: 带宽、 优先级和 /或亲和属性; 链路功 能可以包括: 快速重路由 FRR、 备份标记交换路径 LSP和 /或自动带宽调整。 为帮助理解, 下面对部分链路参数和部分链路属性作简单介绍。
本领域技术人员可以理解的是, 带宽是 MPLS TE的基本属性之一。 在建 立基于约束路由的标签交换路径 ( CR-LSP , Constraint-based Routed-Label Switched Path ) 时, 可以指定 MPLS TE的带宽, 并根据带宽要求确定合适的 路径。 基于流量工程扩展的资源预留协议(RSVP-TE, Resource ReSerVation Protocol-Traffic Engineering )信令可以携带带宽信息, 在沿路径的各个节点实 施带宽预留。 CR-LSP建立成功后,能够为对应的业务提供所要求的带宽保证。
为了更好的管理连接链路, 可以为链路配置优先级。 如果在建立 CR-LSP 的过程中, 无法找到满足所需带宽要求的路径, 则拆除某一条优先级较低的 CR-LSP, 占用为它分配的带宽资源, 这种处理方式称为抢占 ( Preemption )。
CR-LSP 可以使用建立优先级 (Setup Priority ), 保持优先级(Holding
Priority )两个优先级属性来决定是否可以进行抢占。 优先级的取值可以为从 0 到 7的整数。 取值越小, 优先级越高, 7为最低优先级。
亲和属性用来表示连接链路的颜色。 为连接链路配置亲和属性后, 业务传 输***选择连接链路时,将不同连接链路的亲和属性和业务传输***的连接链 路管理组属性进行比较, 决定选择还是避开特定亲和属性的连接链路。如选择 某一连接链路对业务进行传输以后,可以为该连接链路配置与其他连接链路不 同的亲和属性, 这样该业务就会沿着亲和属性相同的连接链路进行传输, 而避 开亲和属性不同的连接链路, 从而实现了对连接链路的选择。
快速重路由 (FRR, Fast ReRoute )在 MPLS TE中是一种局部性保护机 制(也称 TE FRR ), 用于保护 CR-LSP的链路和节点故障, 而且可以对主 LSP 配置带宽保护或非带宽保护。 TE FRR通过预先建立绕过故障的链路或者节点 的旁路功能 Bypass隧道达到保护主 CR-LSP的目的。 当 CR-LSP链路或节点 故障时, 允许流量继续从旁路隧道传输, 同时头节点可以在数据传输不受影响 的同时继续发起主路径的重建。
备份标记交换路径 LSP 在 TE 中被广泛应用, 如: 同一条路径下对主 CR-LSP进行路径备份的 CR-LSP称为备份 CR-LSP„备份 CR-LSP用于实现对 重要 LSP的流量保护。作为流量保护的一个重要组成部分,在主 CR-LSP失败 后,流量需要及时被切换到备份路径上。当入节点感知到主 CR-LSP不可用时, 将流量切换到备份路径上, 当主 CR-LSP路径恢复后再将流量切换回来, 以实 现对主 CR-LSP路径的备份保护。
自动带宽调整可以动态检测流量,并根据检测结果按照实际的带宽需求重 新建立路径。
本领域技术人员可以理解的是,以上链路参数和链路功能均为链路的部分 属性, 当该链路对应于不同业务时,其部分或全部属性也可能不同。举例来说: 当要传输文字业务时, 其所要求的链路的带宽较低, 这时只需要将链路的带宽 配置为较低的带宽就可以顺畅的传输该文字业务。而当所要传输的业务是视频 业务时,该业务所要求的链路带宽较高,这时就需要将链路的带宽配置高一些, 以确保顺畅的传输该视频业务。 当然, 本领域技术人员可以理解, 其他链路属 性也可以根据所要传输业务的特性进行配置以确保该业务的顺畅传输,本发明
不再赘述。
本发明提供的一种隧道配置方法, 可以根据不同业务选择相应的 PE组, 并根据与所述业务对应的隧道模板对 PE组之间的连接链路进行配置, 生成适 合所述业务通信的多个隧道。 由于每一个业务都对应于多个隧道, 因此当多个 相同业务同时需要传输时,可以选择与之对应的多个隧道对多个相同业务同时 进行传输, 实现了隧道的高效率应用。
参考图 2, 示出了本发明一种隧道配置方法实施例 2的流程图, 可以包括 以下步骤:
5201、 将 Λ良务商边缘节点 PE划分为对应于业务的多个 PE组, 生成 PE 组划分信息;
步骤 S201与实施例 1的步骤 S101相同, 不再赘述。
5202、 根据所述 PE组划分信息, 选择与被传输的业务相对应的 PE组; 步骤 S202与实施例 1的步骤 S102相同, 不再赘述。
5203、 将所述 PE组划分信息通过内部网关协议 IGP发送到各 PE中; 内部网关协议 IGP是一种可以应用在自治网络***中用于交换路由信息 的协议, 包括: 路由信息协议 RIP、 开放式最短路径优先 OSPF协议、 内部网 关路由协议 IGRP、 增强网关内部路由线路协议 EIGRP和 IS-IS等。
5204、 控制所述 PE组中各 PE进行两两连接, 生成多个连接链路;
5205、使用与该业务相对应的隧道模版对所述多个连接链路进行配置,生 成多个隧道。
具体的, 可以对连接链路的链路参数和 /或链路功能进行配置, 链路参数 可以包括:带宽、优先级和 /或亲和属性;链路功能可以包括: 快速重路由 FRR、 备份标记交换路径 LSP和 /或自动带宽调整。
本实施例所釆用的方法是使用隧道模版对同一 PE组中生成的所有连接链 路进行配置,在本发明其他实施例中,还可以仅仅对生成的连接链路中的未占 用且可以连通业务目的地址的连接链路进行配置, 这样可以减少配置量。
参考图 3 , 示出了本发明一种隧道配置方法实施例 3的流程图, 可以包括
以下步骤:
S301、 将 Λ良务商边缘节点 ΡΕ划分为对应于业务的多个 ΡΕ组, 生成 ΡΕ 组划分信息;
步骤 S301与实施例 1的步骤 S101相同, 不再赘述。
S302、 根据所述 PE组划分信息, 选择与被传输的业务相对应的 PE组;
5303、 将所述 PE组划分信息通过内部网关协议 IGP发送到各 PE中;
5304、 控制所述 PE组中的各 PE之间的连接路线, 生成多个连接链路;
5305、在所述多个连接链路中的未占用链路中选择可以连通所述业务目的 地址的连接链路并使用与该业务相对应的隧道模版对所选择的连接链路进行 配置, 生成隧道。
通过应用以上技术方案, 本实施例可以有效减少连接链路的配置量。在实 际应用中,可以根据所要发送业务的数量选择与该数量匹配的一个或多个连接 链路, 然后再使用隧道模版进行配置。
参考图 4, 示出了本发明一种隧道配置方法实施例 4的流程图, 可以包括 以下步骤:
5401、 将 Λ良务商边缘节点 PE划分为对应于业务的多个 PE组, 生成 PE 组划分信息;
5402、 根据所述 PE组划分信息, 选择与被传输的业务相对应的 PE组; S403、 控制所述 PE组中各 PE之间的连接路线 , 生成多个连接链路; S404、使用与该业务相对应的隧道模版对所述多个连接链路进行配置,生 成多个隧道;
S405、在所述多个隧道中的未占用隧道中选择可以连通所述业务目的地址 的隧道, 并用该隧道对所述业务进行传输。
通过步骤 S404, 本发明已经生成了可以传输所述业务的多条隧道, 但由 于这些隧道中可能有正在被占用的隧道, 如果选用被占用的隧道传输该业务, 必然造成这条隧道的拥堵, 也没有办法快速且顺畅的传输该业务。 所以, 本发 明选择未占用隧道中可以连通所述业务目的地址的隧道,使用该隧道进行所述 业务的传输。本领域技术人员可以理解的是, 只有当隧道可以连通所述业务的
目的地址时, 该隧道才可能将所述业务传输到目的地址处。 其中, 目的地址可 以为目的路由器的地址。
在实际应用中, 隧道的具体选择方式可以有多种, 如: 在为链路配置优先 级以后生成的隧道将具有优先级,我们可以在能够连通所述业务目的地址且未 占用的隧道中首先选择优先级最高的隧道对所述业务进行传输。当同时出现多 个相同业务时, 可以选择优先级较高的几个隧道同时对这些业务进行传输,从 而保证了业务的快速传输。
本发明提供的隧道配置方法, 可以根据不同业务选择相应的 PE组, 并根 据与所述业务对应的隧道模板对 PE组之间的连接链路进行配置, 生成适合所 述业务通信的多个隧道。 由于每一个业务都对应于多个隧道, 因此当多个相同 业务同时需要传输时,可以选择与之对应的多个隧道对多个相同业务同时进行 传输, 实现隧道的高效率应用。
为方便理解, 现举例说明: 如图 5所示:
具有业务传输功能的网络由控制中心 001、服务商核心设备 Pl、服务商核 心设备 P2、服务商边缘节点 PE1、服务商边缘节点 PE2、服务商边缘节点 PE3 和服务商边缘节点 PE4组成。 为方便理解, 可以^ _定 P1和 P2位于曱省的省 会城市 , PE1和 PE2位于该省的乙地区 (非省会城市 ) , PE3和 PE4位于该省 的丙地区 (非省会城市)。
业务 1为由 PE1发送至 PE3的文字业务, 业务 2为由 PE1发送至 PE4的 视频业务, 业务 3为由 PE2发送至 PE1的语音业务。
根据历史信息中三个业务所使用的 PE的次数分析, 对 PE分组如下: PE组 1包括: PE1、 PE2和 PE3 , 对应于业务 1 ;
PE组 2包括: PE1、 PE2和 PE4, 对应于业务 2;
PE组 3包括: PE1和 PE2, 对应于业务 3。
以上这些 PE组划分信息存储在控制中心 001中, 并通过网络已发送到各
PE中。
当同时出现两个业务 1需要传输时, 选择业务 1所对应的 PE组 1 , 控制
PE组 1中 PE1、 PE2和 PE3之间的连接路线为 PE1-P1-PE3 , PE1-P1-P2-PE3 , PE1-PE2和 PE1-PE2-P2-PE3 , 生成四个连接链路。
假设业务 1(文字业务)对应的隧道模版 1可以配置连接链路的带宽为 1M, 以使生成的隧道满足业务 1 的要求。 则使用隧道模版 1 对 PE1-P1-PE3、 PE1-P1-P2-PE3 , PE1-PE2和 PE1-PE2-P2-PE3进行配置, 生成四个隧道, 带宽 均为 1M。 当同时有两个业务 1需要传输时, 只需要选择这四个隧道中能够成 功传输业务 1的两个隧道分别对两个业务 1进行传输即可。具体的, 这四个隧 道中可能有隧道正在被占用, 而隧道 PE1-PE2无法将业务 1传输到 PE3 ,所以 不能成功传输业务 1。 举例来说: 假设这四个隧道中, PE1-PE2-P2-PE3正在被 占用, 而 PE1-PE2无法将业务 1 传输到 PE3 中, 所以选择 PE1-P1-PE3 和 PE1-P1-P2-PE3对两个业务 1进行传输, 每条隧道对应于一个业务, 从而保证 了隧道的高效应用。
与上述本发明一种隧道配置方法实施例 1所提供的方法相对应,参见图 6, 本发明还提供了一种隧道配置装置实施例 1 , 在本实施例中, 该装置具体可以 包括:

在实际应用中, 本实施例中隧道配置模块 400 可以使用隧道模版对同一 PE组中生成的所有连接链路进行配置, 当然, 还可以仅仅对生成的连接链路 中可以成功传输该业务的一个或多个连接链路进行配置, 这样可以减少配置 量。

对于让各 PE获得 PE组划分信息的方式,本领域技术人员可以理解的是, 各 PE对该存储设备进行数据访问便可以获得具体的 PE组划分信息。 当然, 也可以将存储设备中存储的 PE组划分信息发送到各 PE中 ,使各 PE获得具体 的 PE组划分信息, 本发明在此不做限定。 具体的, PE组划分信息可以通过 内部网关协议 IGP发送到各 PE中。 内部网关协议 IGP可以有多种, 如: IS-IS 协议和 OSPE协议。
参考图 8, 本发明还提供了一种隧道配置装置实施例 3 , 与一种隧道配置 装置实施例 1的区别在于, 还包括: 隧道选择模块 500, 用于在所述多个隧道 中的未占用隧道中选择可以连通所述业务目的地址的隧道,并用该隧道对所述 业务进行传输。
图 6所示的一种隧道配置装置实施例 1中,本发明已经生成了可以传输所 述业务的多条隧道,但由于这些隧道中可能有正在被占用的隧道,如果选用被 占用的隧道传输该业务, 必然造成这条隧道的拥堵,也没有办法快速且顺畅的 传输该业务。所以, 本实施例的隧道选择模块 500选择未占用隧道中可以连通 所述业务目的地址的隧道,使用该隧道进行所述业务的传输。本领域技术人员
