其中, 测试连接命令可以是 uni-ping命令。
其中, 分组传送网设备执行测试连接命令, 在测试连接命令行中可以 得到源 IP地址、 目的 IP地址、 物理出端口及 VLAN信息等, 源 IP地址、 目的 IP地址、 物理出端口为用户必须指定的信息, VLAN信息包括 svlan 及优先级、 cvlan信息等, svlan及优先级、 cvlan信息为用户可以选择指定 的信息。 用户可根据不同的 CIP接入方式指定不同的信息。
其中, 目的 IP地址可任意选定, 但只要保持源 IP地址与目的 IP地址 在同一网段内即可。
其中, 测试连接命令的终止条件包括: 1、 在测试连接命令执行的过程 中, 如果超时没有收到 ICMP响应报文, 则在用户界面打印提示信息 "."。 2、 在测试连接命令执行的过程中按下 ctrl+c键, 则终止。
以执行 uni-ping命令为例,为了不影响公网的 ARP ( Address Resolution Protocol, 地址解析协议)表, 该 uni-ping进程需要单独维护一张 ARP表。 ARP表是一张全局表。 公网 ARP表是在 PROTOCOL进程创建、 添加、 删 除以及访问的。而由于 uni-ping命令是在 PING进程发起的, uni-ping的 ARP 表的创建和查询也是在 ping进程处理。 这里对于客户网边缘设备侧回应的 ARP报文在收包时需要统一从 PROTOCOL进程投递到 ping进程完成以及 ARP表的管理等操作。本实施例主要是防止多进程同时对一张 ARP表操作 造成多进程访问冲突。 分组传送网设备可以从该 ARP表中得到客户网边缘 设备的 MAC地址, 也可从客户网边缘设备侧回应的 ARP报文获取到客户 网边缘设备的 MAC地址。
步骤 S102, 当检测到所述配置信息匹配到 CIP接入方式后, 根据所述 配置信息生成 ICMP请求报文并将所述 ICMP请求报文发送至客户网边缘设 备;
其中,该 ICMP请求报文为单播 ICMP请求报文。客户网边缘设备包括 但不限定于基站或 PC等。
其中, CIP接入方式有多种, 包括物理出端口接入方式、 物理出端口 +VLAN接入方式、 物理出端口 +SVLAN接入方式等等。 配置信息必须与 CIP接入方式保持一致。每次发送 ICMP请求报文前都需要检测配置信息是 否匹配到 CIP接入方式, 防止异常情况而删除 CIP接入方式或者出现检测 错误的结果。
其中, 当检测到配置信息匹配到 CIP接入方式后, 分组传送网设备发 送 ICMP请求报文给客户网边缘设备, 并等待客户网边缘设备返回 ICMP 响应 4艮文。
步骤 S103, 通过所述 CIP接入方式对应的接口接收所述客户网边缘设 备返回的 ICMP响应报文,根据所述 ICMP请求报文及 ICMP响应报文确定 所述客户网边缘设备和分组传送网设备的用户侧接口之间的连通性。
当分组传送网设备匹配到 CIP接入方式并发送 ICMP请求报文后, 通 过 CIP接入方式对应的接口接收客户网边缘设备返回的 ICMP响应报文, 对 ICMP请求报文及 ICMP响应报文进行处理后,可以确定客户网边缘设备 和分组传送网设备的用户侧接口之间的连通性。
在一优选实施例中, 将 ICMP请求报文发送至客户网边缘设备的步骤 之前还包括: 根据所述配置信息添加 ACL规则。 具体为: 将配置信息发送 至分组传送网设备的驱动, 由驱动添加 ACL ( Access Control List, 访问控 制列表 )规则, 以接收到 ICMP应答报文时通过该 ACL规则发送 ICMP应 答报文至中央处理器进行处理。
当遇到异常情况(如重启线卡)时, ACL规则不会生效, 需要删除该 ACL规则然后重新下发 ACL规则, 避免原 ACL规则残留。
当测试连接命令结束时, 需要通知驱动删除与测试连接命令相应的 ACL规则信息, 节省驱动 ACL表项空间。
其中,在一优选实施例中,如图 2所示,上述步骤 S101包括以下步骤: 步骤 S1011,根据测试连接命令行得到源 IP地址、 目的 IP地址、 VLAN 信息及物理出端口;
步骤 S1012,判断测试连接命令是否下发的为小组( smart group )接口; 若是 smart group接口, 则进入步骤 SI 013, 若不是 smart group接口, 则进 入步骤 S1014;
步骤 S1013 , 获取所述 smart grou 接口的成员接口信息, 进入步骤 S1014;
步骤 S1014, 判断所述分组传送网设备是否为集中式设备; 若是, 则进 入步骤 S1016, 若否, 则进入步骤 S1015;
步骤 S1015 , 发信息到线卡上进行处理, 进入步骤 S1016;
步骤 S1016, 整合源 IP地址、 目的 IP地址、 VLAN信息、 物理出端口 及 smart grou 接口的成员接口信息, 得到配置信息。
其中, 可在步骤 S1012之前创建相关定时器, 可包括超时定时器、 限 速定时器、 OAM回显扫描定时器等。 限速定时器是在一定周期内控制发包 的个数。 当测试连接命令结束时, 删除创建的定时器信息。
其中, 分组传送网设备为分布式设备时, 则测试连接命令是主控在处 理, 需要将信息发到线卡上进行处理。
其中,在一优选实施例中,如图 3所示,上述步骤 S102包括以下步骤: 步骤 S 1021, 当检测到所述 VLAN信息及物理出端口匹配到 CIP接入 方式后,根据所述配置信息生成 ICMP请求报文后并封装所述 ICMP请求报 文;
步骤 S1022, 判断是否能根据所述目的 IP地址查找到所述分组传送网 设备维护的 ARP表中相应的 MAC地址, 若是, 则进入步骤 S1024, 否则 进入步骤 S1023;
步骤 S 1023, 将 ICMP请求报文緩存, 广播发送 ARP请求报文, 学习 客户网边缘设备的 ARP, 当学习到 ARP后, 添加到测试连接进程维护的 ARP表中;
步骤 S1024, 将所述 ICMP请求 文发送至客户网边缘设备。
其中,在封装所述 ICMP请求报文的载荷部分,计算 ICMP请求报文的 校验和后, 封装对应的 IP报文载荷部分并计算 IP报文的校验和。
其中, 若能够学习客户网边缘设备的 ARP, 要对 ICMP请求报文的源 IP地址、 目的 IP地址、 物理出端口等信息进行测试连接规则的匹配检查, 符合则添加到测试连接进程维护的 ARP表中。
其中,在一优选实施例中,如图 4所示,上述步骤 S103包括以下步骤: 步骤 S1031,通过所述 ACL规则将所述 ICMP响应报文及 ARP响应报 文发送至中央处理器;
步骤 S1032,所述中央处理器通过检测所述 ICMP响应报文的内容是否 与所述 ICMP请求 文的内容相对应确定所述客户网边缘设备和分组传送 网设备的用户侧接口之间的连通性。
本实施例中央处理器处理 ICMP 响应 文的过程为: 通过检测 ICMP 响应报文的内容与 ICMP请求报文的内容是否相对应来判断客户网边缘设 备与分组传送网设备的 U I侧之间是否能够连通。 ICMP响应报文的内容 与 ICMP请求报文内容除头部不相同之外, 其他的内容全都相同。 具体的 检测过程包括:检测 ICMP响应报文是否为其自身发送的 ICMP请求报文的 响应,若是,则进一步检测 ICMP响应报文的内容是否与 ICMP请求报文的 内容相对应, 若是, 则客户网边缘设备与分组传送网设备的 U I侧之间连 通性较好。
优选地, 当接收客户网边缘设备的 ICMP 响应报文后, 可计算 ICMP 请求报文从发送到接收到 ICMP响应报文的这一段时间的 RTT ( Round-Trip Time, 往返时延)。 RTT可以在一定程度上反映出两点间距离的远近, 也可 以作为检测客户网边缘设备与分组传送网设备的 U I侧之间连通性的一个 参考值。
具体地, 可在发送 ICMP请求报文时打上时间戳并保存起来, 在回显 信息时获取当前的时间戳, 两者的差值就是 RTT的数值。 同时也可以计算 出连续 ping包的最大 /最小 /平均抖动的时间。计算方法如下: 如果接收到的 ICMP响应报文数量大于 1,则用本次计算出来的 RTT值减去上一次计算出 来的 RTT值, 即为本次抖动的时间差。 当接收到的 ICMP响应报文数量正 好为 2 时, 此时最大抖动时间和最小抖动时间都为当前的抖动时间。 当收 到的响应报文数量大于 2 时, 重新计算出当前的抖动时间, 并和之前的最 大抖动时间和最小抖动时间进行比较。 如果当前的抖动时间大于之前的最 大抖动时间, 则把当前的抖动时间作为目前的最大抖动时间。 如果当前的 抖动时间小于之前的最小抖动时间, 则把当前的抖动时间作为目前的最小 抖动时间。
通过上述的描述可以看出: 本实施例通过分组传送网设备运行测试连 接命令得到配置信息, 当该配置信息匹配到 CIP接入方式后, 分组传送网 设备发送 ICMP请求报文并接收客户网边缘设备返回的 ICMP响应报文,根 据从分组传送网设备处理返回的 ICMP 响应报文, 并确定客户网边缘设备 和分组传送网设备的用户侧接口之间的连通性, 由于本实施例为 CIP接入 方式, 分组传送网设备与客户网边缘设备实现直连, 不需要经过路由器, 即不跨跳, 实现方法简单, 而 CIP接入方式有多种, 可根据不同的 CIP接 入方式进行选择, 操作方法灵活, 大大提高检测效率。
如图 5 所示, 本发明一实施例提出一种分组传送网设备, 分组传送网 设备包括: 获取模块 101、 报文发送模块 102、 确定模块 103; 其中,
获取模块 101, 可以是分组传送网设备的接收端口, 配置为发起测试连 接命令, 并根据测试连接命令得到配置信息;
其中, 测试连接命令可以是 uni-ping命令。
其中, 分组传送网设备执行测试连接命令, 在测试连接命令行中可以 得到源 IP地址、 目的 IP地址、 物理出端口及 VLAN信息等, 源 IP地址、 目的 IP地址、 物理出端口为用户必须指定的信息, VLAN信息包括 svlan 及优先级、 cvlan信息等, svlan及优先级、 cvlan信息为用户可以可选择指 定的信息。 用户可根据不同的 CIP接入方式指定不同的信息。
其中, 目的 IP地址可任意选定, 但只要保持源 IP地址与目的 IP地址 在同一网段内即可。
以执行 uni-ping命令为例,为了不影响公网的 ARP ( Address Resolution
Protocol, 地址解析协议)表, 该 uni-ping进程需要单独维护一张 ARP表。 ARP表是一张全局表。 公网 ARP表是在 PROTOCOL进程创建、 添加、 删 除以及访问的。而由于 uni-ping命令是在 ing进程发起的, uni-ping的 ARP 表的创建和查询也是在 ping进程处理。 这里对于客户网边缘设备侧回应的 ARP报文在收包时需要统一从 PROTOCOL进程投递到 PING进程完成以及 ARP表的管理等操作。本实施例主要是防止多进程同时对一张 ARP表操作 造成多进程访问冲突。 分组传送网设备可以从该 ARP表中得到客户网边缘 设备的 MAC地址, 也可从客户网边缘设备侧回应的 ARP报文获取到客户 网边缘设备的 MAC地址。
报文发送模块 102,可以由分组传送网设备的处理器与发送端口的结合 实现, 配置为当检测到所述配置信息匹配到 CIP接入方式后, 根据所述配 置信息生成 ICMP请求报文并将所述 ICMP请求报文发送至客户网边缘设 备;

当匹配到 CIP接入方式并发送 ICMP请求报文后, 报文处理模块 103 通过 CIP接入方式对应的接口接收客户网边缘设备返回的 ICMP响应报文, 对 ICMP请求报文及 ICMP响应报文进行处理后,可以确定客户网边缘设备 和分组传送网设备的用户侧接口之间的连通性。
在一优选实施例中, 分组传送网设备还包括添加模块, 配置为根据所 述配置信息添加 ACL规则。 具体为: 将配置信息发送至分组传送网设备的 驱动, 由驱动添加 ACL ( Access Control List, 访问控制列表)规则, 以接 收到 ICMP应答 文时通过该 ACL规则发送 ICMP应答 文至中央处理器 进行处理。
其中, 在一优选实施例中, 如图 6所示, 获取模块 101包括: 获取单元 1011, 配置为根据测试连接命令行得到源 IP地址、 目的 IP 地址、 VLAN信息及物理出端口;

其中, 分组传送网设备为分布式设备时, 则测试连接命令是主控在处 理, 需要将信息发到线卡上进行处理。
其中, 在一优选实施例中, 如图 7所示, 报文发送模块 102包括: 封装单元 1021, 配置为当检测到所述 VLAN信息及物理出端口匹配到
CIP接入方式后, 根据所述配置信息生成 ICMP请求报文并封装所述 ICMP 请求 4艮文;
判断单元 1022,配置为判断是否能根据所述目的 IP地址查找到所述分 组传送网设备维护的 ARP表中相应的 MAC地址;
发送单元 1023, 配置为根据所述 MAC地址将所述 ICMP请求报文发 送至客户网边缘设备。
其中,在封装所述 ICMP请求报文的载荷部分,计算 ICMP请求报文的 校验和后, 封装对应的 IP报文载荷部分并计算 IP报文的校验和。
其中, 若能够学习客户网边缘设备的 ARP, 要对 ICMP请求报文的源 IP地址、 目的 IP地址、 物理出端口等信息进行测试连接规则的匹配检查, 符合则添加到测试连接进程维护的 ARP表中。
在一优选实施例中, 如图 8所示, 确定模块 103包括:

优选地, 当接收客户网边缘设备的 ICMP 响应报文后, 可计算 ICMP 请求报文从发送到接收到 ICMP响应报文的这一段时间的 RTT(Round-Trip Time, 往返时延)。 RTT可以在一定程度上反映出两点间距离的远近, 也可 以作为检测客户网边缘设备与分组传送网设备的 U I侧之间连通性的一个 参考值。
具体地, 可在发送 ICMP请求报文时打上时间戳并保存起来, 在回显 信息时获取当前的时间戳, 两者的差值就是 RTT的数值。 同时也可以计算 出连续 ping包的最大 /最小 /平均抖动的时间。计算方法如下: 如果接收到的 ICMP响应报文数量大于 1,则用本次计算出来的 RTT值减去上一次计算出 来的 RTT值, 即为本次抖动的时间差。 当接收到的 ICMP响应报文数量正 好为 2 时, 此时最大抖动时间和最小抖动时间都为当前的抖动时间。 当收 到的响应报文数量大于 2 时, 重新计算出当前的抖动时间, 并和之前的最 大抖动时间和最小抖动时间进行比较。 如果当前的抖动时间大于之前的最 大抖动时间, 则把当前的抖动时间作为目前的最大抖动时间。 如果当前的 抖动时间小于之前的最小抖动时间, 则把当前的抖动时间作为目前的最小 抖动时间。
