propagation. BACKGROUND OF THE INVENTION A PTN (Packet Transport Network) product supports a convenient provisioning and plug-and-play function. For a new deployment network, all devices need to be deployed with a physical layer connection, and the device can be managed by powering on the device. However, the PTN products are in the same area by default. The newly opened network needs to be reallocated according to the current network conditions, but currently it can only be manually configured. As the scale of the carrier network is expanding, the number of network elements in the network is increasing, and the labor cost required to allocate the domain is also increased, and the network opening efficiency is seriously affected. For example, the operator has to open a network with 1000 network elements, of which 150 network elements of the backbone domain are planned, and the remaining 850 network elements need to be divided into different non-backbone domains, which are divided into 50 network elements per domain. It is divided into 17 non-backbone domains. If non-backbone areas need to be manually configured, ideally, it takes 30 seconds to configure one network element and 7 hours for 850 network elements. The larger the network, the more time it takes, and the low opening efficiency is a big human and financial burden for operators.

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments. A first embodiment of the present invention is a method for realizing automatic area reproduction. The PTN network includes a breeding source network element and a propagated network element connected thereto, and a global area for any breeding source network element or a propagated network element. When the breeding function is disabled, the regional breeding function of all MCC interfaces on the NE cannot be enabled. As shown in Figure 1, the process performed by the source network element includes: Step A1: Turning on the area breeding function of the MCC interface connected to the source network element on the breeding source network element; Step A2: Passing the breeding network The MCC interface that has opened the regional breeding function automatically sends a regional breeding request message to the adjacent propagated network element, and is used to modify the network from the adjacent propagated network element to the remaining propagated network elements. The domain configuration information of the element is as follows: Step A3: When the response message sent by the adjacent propagated network element is received, the global area reproduction function of the network element is disabled. Preferably, the received response message is verified, and when the domain deployment on the adjacent propagated network element fails, the alarm is reported. Optionally, the process performed by the propagation source network element further includes: if the global area propagation function is closed, if the area propagation request message is received, the response message is directly replied, and the adjacent The propagated network element also closes its global region reproductive function, which contributes to the smooth end of the regional breeding process of this embodiment. The load part of the area reproduction request packet includes: an area ID of the MCC interface and an area type of the network element, and preferably, the router ID of the propagation source network element. The reason that the router ID of the breeding source network element is set in the payload part of the area breeding request message is to avoid the risk of the source network element modifying the domain configuration information during the area automatic breeding process, for example: the breeding If the source network element receives the area propagation request packet before receiving the response packet, the source ID of the area is the same as the router ID of the local network element. The area request message is returned to itself, so the global area reproduction function of the network element is turned off. Preferably, the method further includes: pre-initiating the global region breeding function of any breeding source network element or the propagated network element by default; or, opening the MCC connected to the breeding source network element on the breeding source network element.

According to a sixth embodiment of the present invention, a propagated network element, for any of the propagated network elements in the PTN network, when the global area reproduction function is closed, the regional reproduction function of all MCC interfaces on the network element cannot be opened; Preferably, initially, the global region breeding function of the breeding source network element and the propagated network element is enabled by default, and the regional breeding function of the MCC interface of each network element is disabled by default. The area propagation request message hops through the upstream neighbor network element, the local network element, and the downstream neighbor network element according to the direction of the delivery area request packet. The propagated network element includes a second processor, and the second processor The device is configured to: receive the area propagation request packet sent by the upstream neighboring network element, and modify the domain configuration information of the local network element according to the area propagation request message; specifically, the payload part of the area propagation request message includes: The area ID of the MCC interface and the area type of the network element; the second processor is specifically configured to: modify the area ID of all MCC interfaces on the network element to be used in the payload part of the area propagation request message The area ID of the configured MCC interface is the same, and the area type of the NE is the same as the area type of the NE in the payload part of the area. The area propagation function of the remaining MCC interfaces except the MCC interface for receiving the propagation request packet of the area is enabled, and the area propagation request is sent to the corresponding neighboring network element through the remaining MCC interfaces. The payload of the packet is the same as the payload of the regional breeding request packet received by the local network element. At the same time, the upstream neighbor NE sends the response packet to the upstream neighboring network packet. When the response message is received, the global area reproduction function of the network element is disabled. The following takes the domain configuration information required for automatic propagation from the backbone domain boundary network element to the non-backbone domain in the PTN network as an example. The seventh to tenth embodiments and application examples are introduced to explain the technical solution of the present invention in detail. A seventh embodiment of the present invention provides a method for automatically reproducing a non-backbone area. A backbone domain is defined in the PTN network, and the backbone domain is mainly used to interconnect other OSPF (Open Shortest Path First) areas. OSPF is a non-backbone domain. As is well known in the art, a network element connected to a non-backbone domain in a backbone domain is called a boundary network element. The MCC interface that connects the border NEs of the backbone domain to the non-backbone domain is called the non-backbone domain MCC interface. The global zone propagation function that is enabled by default is set for all NEs, and the default cell regeneration function is set for all MCC interfaces. In any of the border NEs or any network element in the non-backbone domain, when the global area breeding function is disabled, the area breeding function of all MCC interfaces on the network element is also closed, that is, the area breeding function of any MCC interface is to be enabled. The premise is that the global region breeding function must be enabled. The process performed by the border network element, as shown in FIG. 3, includes the following steps: Step S101: Enable a region breeding function of the non-backbone domain MCC interface on the border network element; Step S102: Open the non-backbone domain The MCC interface automatically sends a region breeding request message to the neighboring network element in the non-backbone domain, and is configured to modify the domain configuration information of each network element hop by hop in the non-backbone domain from the neighboring network element; The load part of the text includes: an area ID of the non-backbone domain MCC interface and an area type of the border network element; Step S103: When receiving the response message sent by the neighboring network element, the global area reproduction function of the network element is disabled For the situation that some border NEs may encounter, the following steps are designed: In the case that the global area breeding function is closed, if the area breeding request message is received, the response message is directly replied. The response message in the embodiment of the present invention may be a private message, or may be implemented by extending a related protocol message, such as a HELLO message. Considering the delay of the network transmission and the delay of the processing of the network element itself, some extreme situations may occur during the actual area reproduction. For example, the boundary network element receives the area propagation request message before receiving the response message. In this case, because the global area breeding function of the border network element has not been closed, the border network element can modify the domain configuration information based on the received area propagation request packet, resulting in a non-backbone area of the network element of the backbone domain. Reproduction, which leads to errors in non-backbone reproduction. For this situation, it is preferable that the payload part of the area breeding request message in this embodiment further includes: a router ID of the border network element; and the situation that the border network element receives the area breeding request message before receiving the response message. When the router ID in the payload part of the area propagation request packet is the same as the router ID of the local network element, the global area breeding function of the local network element is disabled. In addition, according to the diversity of the PTN network networking, the execution flow of the boundary network element is further designed as follows for certain specific networking scenarios: The first specific networking scenario: When a boundary network element in the backbone domain is simultaneously When the two or more neighboring network elements in a closed-loop network of the backbone domain are connected, the process performed by the boundary network element, as shown in FIG. 4, includes the following steps: Step S201: Enable the boundary network element and the two The regional breeding function of at least one connected non-backbone domain MCC interface of more than one neighbor network element. In the step S202, the non-backbone domain MCC interface is automatically configured to automatically send a region breeding request packet to the corresponding neighboring network element in the non-backbone domain, and is used to start hopping in the non-backbone domain from the corresponding neighboring network element. Modify the domain configuration information of each NE. Step S203: When receiving the response message sent by the neighboring network element, shutting down the global area breeding function of the local network element; if the global area breeding function of the boundary network element is closed, if the area is propagated If the message is requested, the response message is directly replied. The second specific networking scenario: When two or more border NEs in the backbone domain are connected to the same closed-loop network in the non-backbone domain, only the global region reproduction function of one boundary NE in all the boundary NEs is enabled by default. Turn off the global region propagation function of the remaining boundary NEs. Step S101 S103 is performed for the boundary network element that is enabled by default in the global area propagation function. If the global area propagation function of the boundary network element is closed, if the area propagation request message is received, the response message is directly replied. In the following, the process performed by any network element in the non-backbone domain is performed. According to the direction of the propagation request message in the delivery area, the area propagation request packet hops through the upstream neighbor network element, the local network element, and the downstream neighbor network. The process performed by any network element in the non-backbone domain, as shown in FIG. 5, includes the following steps: Step S301: Receive an area breeding request packet sent by an upstream neighboring network element, and use the area to reproduce the request packet. Modifying the domain configuration information of the local network element; Step S302: Opening the rest of the local network element except the MCC interface for receiving the propagation request packet of the area

At the same time, the upstream neighbor NE sends a response packet to the sending area request packet. The response The payload of the packet includes: The current domain configuration information of the NE, which is used by the receiving end to verify the response packet. The content of the domain configuration information includes: the area ID of each MCC interface on the NE, and the area type of the local NE. Specifically, any network element in the non-backbone domain modifies the domain configuration information of the local network element based on the area propagation request packet, including: modifying the area ID of all MCC interfaces on the local network element to the area breeding request report The area ID of the MCC interface in the payload portion is changed, and the area type of the local network element is modified to be consistent with the area type of the boundary network element in the payload portion of the area propagation request message. Step S303: When receiving the response packet sent by the downstream neighboring network element, the global area breeding function of the local network element is disabled. For the situation that some network elements in the non-backbone domain may encounter, the following steps are designed: When the breeding function is off, if a regional reproduction request message is received, the response message is directly replied. Preferably, any network element in step S303, when receiving the response message, also checks the response message, and reports the alarm when the domain deployment on the neighboring network element fails. For example, before the global area propagation function of the NE is disabled, the response packet is verified. When the domain deployment on the neighbor NE is completed, the global area propagation function of the NE is disabled. When the domain deployment on the neighboring NE fails, the global area propagation function of the NE is disabled and an alarm is reported to notify the maintenance personnel. In this embodiment, preferably, the payload part of the area propagation request message further includes: a quantity of the area breeding network element, configured to enable the user to control the number of the breeding network element, for example, for an already stable network, it may be only a part of the expansion. Equipment, you need to limit the number of breeding network elements at this time, to avoid affecting the regional configuration of the entire network. When the default value of the number of regional breeding network elements is set to 0, it is also a secure processing mechanism. In addition, the parameter setting of the number of breeding network elements in the area can also enable the user to limit the size of the non-backbone domain, that is, the number of network elements included in the non-backbone domain. For any network element in the non-backbone domain, when the area propagation request message is sent, the number of regional breeding network elements in the payload content of the area propagation request message is reduced by one, and the remaining payload content is received by the local network element. The payload content of the regional reproduction request message is the same. According to the eighth embodiment of the present invention, a border network element in the backbone domain is configured as a backbone domain in the PTN network, and the MCC interface connected to the non-backbone domain on the border network element of the backbone domain is referred to as a non-backbone domain MCC interface. Set the global area breeding function that is enabled by default for all NEs. Set the default area regeneration function for all MCC interfaces. For any network element in any boundary or non-backbone domain, when the global area propagation function is disabled. The regional breeding function of all MCC interfaces on the NE is also closed. That is, the premise of the regional breeding function of any MCC interface must be enabled. The boundary network element in the backbone domain, as shown in FIG. 6, includes the following components: The function opening module 101 is configured to enable the area breeding function of the non-backbone domain MCC interface on the boundary network element. The packet sending module 102 is configured to automatically send a region breeding request packet to the neighboring network element in the non-backbone domain by using the non-backbone domain MCC interface that is enabled, and set the packet to start in the non-backbone domain from the neighboring network element. Modify the domain configuration information of each NE by hop by hop. The payload part of the area propagation request packet includes the area ID of the local MCC interface and the area type of the local border network element. The packet processing module 103 is configured to: when receiving the response message sent by the neighboring network element, turn off the global area breeding function of the local network element; and design a message processing module for the situation that may be encountered by some border network elements. 103 is further configured to directly reply the response message if the area propagation request message is received when the global area reproduction function of the network element is closed. Considering the delay of the network transmission and the delay of the processing of the network element itself, some extreme situations may occur during the actual area reproduction. For example, the boundary network element receives the area propagation request message before receiving the response message. In this case, because the global area breeding function of the border network element has not been closed, the border network element can modify the domain configuration information based on the received area propagation request packet, resulting in a non-backbone area of the network element of the backbone domain. Reproduction, which leads to errors in non-backbone reproduction. For this situation, the load part of the area breeding request message in this embodiment further includes: a router ID of the border network element; the message processing module 103 is further configured to receive the area before receiving the response message. In the case of the propagation request message, when the router ID in the payload portion of the region's reproduction request message is the same as the router ID of the local network element, the global region reproduction function of the local network element is turned off. In this embodiment, the packet processing module 103 is further configured to: when the response packet is received, the response packet is verified, and when the domain deployment on the neighboring network element fails to be reported, the report is reported. police. For example, before the global area propagation function of the NE is disabled, the response packet is verified. When the domain deployment on the neighbor NE is completed, the global area propagation function of the NE is disabled. When the domain deployment on the neighboring NE fails, the global area propagation function of the NE is disabled and an alarm is reported to notify the maintenance personnel. In addition, according to the diversity of the PTN network networking, for some specific networking scenarios, the functions of each module of the boundary network element are further designed as follows: The first specific networking scenario: When a boundary network element in the backbone domain is simultaneously When two or more neighbor NEs in a closed-loop network of a non-backbone domain are connected: The function opening module 101 is specifically configured to enable the area breeding function of the non-backbone domain MCC interface connected to at least one of the two or more neighboring network elements on the border network element. The packet sending module 102 is configured to automatically send a region breeding request message to the corresponding neighboring network element located in the non-backbone domain by using the non-backbone domain MCC interface that is enabled. The second specific networking scenario: When two or more border NEs in the backbone domain are connected to the same closed-loop network in the non-backbone domain, only the global region reproduction function of one boundary NE in all the boundary NEs is enabled by default. The global area breeding function of the remaining border NEs is disabled. The bounding network elements that are enabled by default for the global area breeding function, the component modules perform corresponding functions. According to a ninth embodiment of the present invention, a network element in a non-backbone domain is defined as a backbone domain in a PTN network, and an MCC interface connected to a non-backbone domain on a border network element of the backbone domain is referred to as a non-backbone domain MCC interface. Set the global area breeding function that is enabled by default for all NEs. Set the default area regeneration function for all MCC interfaces. For any network element in any boundary or non-backbone domain, when the global area propagation function is disabled. The area propagation function of all MCC interfaces on the NE cannot be enabled. The area propagation request packet hops through the upstream neighbor NE, the local NE, and the downstream neighbor NE according to the direction of the propagation request packet. The network element in the backbone domain, as shown in Figure 7, includes:
1 )配置修改模块 201， 设置为接收上游邻居网元发来的区域繁殖请求报文， 基于 该区域繁殖请求报文修改本网元的域配置信息； 具体的， 该区域繁殖请求报文的载荷部分包括： 非骨干域 MCC接口的区域 ID和 边界网元的区域类型。配置修改模块 201将本网元上所有 MCC接口的区域 ID修改为 与该区域繁殖请求报文载荷部分中的所述 MCC接口的区域 ID—致，将本网元的区域 类型修改为与该区域繁殖请求报文载荷部分中所述边界网元的区域类型一致。 1) The configuration modification module 201 is configured to receive the area propagation request packet sent by the upstream neighboring network element, and modify the domain configuration information of the local network element according to the area propagation request message; specifically, the area is responsible for the payload of the request packet The part includes: the area ID of the non-backbone domain MCC interface and the area type of the border network element. The configuration modification module 201 modifies the area ID of all the MCC interfaces on the local network element to the area ID of the MCC interface in the payload portion of the area propagation request message, and modifies the area type of the local network element to the area. The area types of the boundary network elements in the payload part of the reproduction request message are the same.
2)功能开启执行模块 202， 设置为开启本网元上除用于接收该区域繁殖请求报文 的 MCC接口外的其余 MCC接口的区域繁殖功能， 通过其余 MCC接口向相应的邻居 网元发送区域繁殖请求报文， 发出的区域繁殖请求报文的载荷内容与本网元接收到的 区域繁殖请求报文的载荷内容相同； 同时， 向发来区域繁殖请求报文的上游邻居网元 回送应答报文， 该应答报文的载荷内容为本网元当前的域配置信息， 该域配置信息的 内容包括： 本网元上各 MCC接口的区域 ID、 本网元的区域类型； 3 )应答报文处理模块 203， 设置为当接收到下游邻居网元发来的应答报文时， 关 闭本网元的全局区域繁殖功能； 针对非骨干域中的部分网元可能遇到的情况， 设计应 答报文处理模块 203还设置为在本网元的全局区域繁殖功能关闭的情况下， 若收到区 域繁殖请求报文， 则直接回复应答报文。 优选的， 应答报文处理模块 203， 还设置为在收到应答报文时， 对该应答报文进 行校验， 在发现所述邻居网元上的域部署失败时， 上报告警。 比如： 在关闭本网元的 全局区域繁殖功能之前， 对该应答报文进行校验， 在确认所述邻居网元上的域部署完 成时， 关闭本网元的全局区域繁殖功能； 在发现所述邻居网元上的域部署失败时， 关 闭本网元的全局区域繁殖功能并上报告警以通知维护人员。 本实施例中， 优选的， 该区域繁殖请求报文的载荷部分还包括： 区域繁殖网元数 量， 用于使用户能够控制繁殖网元的数量， 比如对于一个已经稳定的网络， 可能只是 扩容部分设备， 此时就需要限制繁殖网元数量了， 避免影响整个网络的区域配置。 将 区域繁殖网元数量的默认值设为 0时， 也是一种安全处理机制。 另外， 通过该区域繁 殖网元数量这一参数设置， 还可以使用户根据需要限定非骨干域的规模， 即非骨干域 中所包含的网元的数量。 针对非骨干域中的任一网元， 功能开启执行模块 202还设置为： 每当发出区域繁 殖请求报文时， 该区域繁殖请求报文的载荷内容中的区域繁殖网元数量减一， 其余载 荷内容与本网元接收到的区域繁殖请求报文的载荷内容相同。 本发明第十实施例， 一种实现非骨干区域自动繁殖的系统， 在 PTN网络中确定一 个骨干域，将骨干域的边界网元上与非骨干域连接的 MCC接口称为非骨干域 MCC接 口， 为所有网元设置默认开启的全局区域繁殖功能， 为所有 MCC接口设置默认关闭 的区域繁殖功能； 针对任一边界网元或者非骨干域中的任一网元来说， 全局区域繁殖 功能关闭时， 该网元上所有 MCC接口的区域繁殖功能均无法开启； 所述系统包括： 如前面实施例所述的骨干域的边界网元以及如前面实施例所述的非骨干域中的网元。 为了更好地说明本发明的目的、 技术方案和有益效果， 下面基于上述实施例， 结 合图 8~10 介绍三个本发明的应用实例， 对本发明技术方案的实施作进一步的详细描 述。 区域繁殖需要维护人员先确定一个骨干域， 然后按组网规划分配骨干域中所有网 元设备 MCC接口所连接的区域，然后通过开启骨干域中 ABR (区域边界路由器， Area Border Router) 网元上与非骨干域连接的 MCC接口的区域繁殖功能， 从该 ABR网元 (即上述实施例中的边界网元） 开始由近及远的在非骨干域内所有网元上进行自动配 置， 配置过程逐跳进行， 整个过程无需人工干预。 应用实例一 以图 9中骨干域的 E1网元向与其连接的非骨干域 AREA2为例， 来阐述区域繁 殖过程。 对于支持便捷开通功能的 PTN设备来说， 所有设备默认开启 DCN (数据通 信网络， Data Communication Network)功能， 并且当物理端口相连且处于 up状态后， DCN功能将自动创建 MCC接口。一台网元设备上的各 MCC接口默认处于同一个域。 如图 8所示， 本应用实例的非骨干域繁殖流程如下： 第一步， 确定一个骨干域， 为骨干域内所有网元分配骨干域 MCC接口与非骨干 域 MCC接口， 如步骤 S201 : 步骤 S201 , 骨干区域部署。 具体的， 为骨干域网元 NE1 E4分别分配各 MCC接口区域。 以网元 E1为例， 由于网元 E1 的 MCC13接口、 MCC20接口与骨干域内的网元设备相连， 将这两个 MCC接口的区域 ID配置为 0.0.0.0， 代表的是骨干域； 由于 MCC1接口、 MCC12接 口均与 AREA2相连， 将这两个 MCC接口的区域 ID配置为 0.0.0.2， 代表的是非骨干 域。 按此方法依次配置网元 E2 E4的各 MCC接口的区域 ID。 第二步， 开启骨干网中 ABR网元的非骨干域 MCC接口的区域繁殖功能， 已开启 区域繁殖功能的 MCC接口自动向与其连接的非骨干域邻居网元发送区域繁殖请求报 文， 如步骤 S205: 步骤 S205, 开启 ABR网元的 MCC接口的区域繁殖功能。 具体的， 将网元 NE1的非骨干域 MCC接口的区域繁殖功能开启。 由于 MCC1接 口、 MCC12接口均与同一个非骨干域相连， 所以只需要开启其中一个 MCC接口下的 区域繁殖功能即可。 这里以开启 MCC1接口下的区域繁殖功能为例， 此处不需要控制 区域繁殖节点数， 需要将区域繁殖节点数配置为一个无穷值， 区域繁殖功能开启后， MCC1接口向其邻居网元 E5发送区域繁殖请求报文， 载荷部分携带本 MCC接口区 域 ID、 区域类型等信息， 区域类型指的是 OSPF协议中所规定的区域类型信息， 此处 不详述。 第三步， 非骨干域邻居网元接收到区域繁殖请求报文后， 先校验报文中的 ROUTER-ID非自己后， 根据该请求报文确定本网元各 MCC接口所属区域， 开启除与 上游网元接口之外的所有 MCC接口的区域繁殖功能， 并发送区域繁殖请求报文， 同 时向上游网元回送应答报文。 上游网元接收到应答报文后， 关闭自身全局区域繁殖功 能与 MCC接口区域繁殖功能。 步骤分解见步骤 S210、 S215、 S220、 S225。 步骤 S210， 邻居网元完成 MCC接口的域配置。 具体的，网元 E5收到区域繁殖请求报文后，根据载荷信息将本网元上所有 MCC 接口的区域 ID修改为 0.0.0.2。 步骤 S215, 邻居网元开启 MCC接口的区域繁殖功能。 具体的， 网元 E5开启本网元上除 MCC2接口外的所有 MCC接口的区域繁殖功 能， 即自动开启 MCC3、 MCC10接口的区域繁殖功能。 当该区域繁殖功能开启后， 网 元 E5立即通过 MCC3、 MCC10接口向其下游邻居网元 E8、 E6发送区域繁殖请 求报文，请求报文载荷部分采用复制网元 E1的 MCC1接口发出的区域繁殖请求报文 的载荷内容。 同时， 网元 E5 回送应答报文给网元 E1， 应答报文载荷内容为网元 E5的域配置信息。 网元 E1收到的应答报文后， 对其进行校验， 若确认域部署完成 则关闭全局区域繁殖功能（见步骤 S230) ， 若域配置信息校验不通过， 则在关闭全局 区域繁殖功能的同时还要以告警形式通知维护人员 （见步骤 S235 ) 步骤 S220, 下游邻居网元完成域配置。 具体的， 网元 E8、 网元 E6收到网元 E5的区域繁殖请求报文后， 各自修改 本网元所有 MCC接口的区域 ID为 0.0.0.2。 步骤 S225, 下游邻居网元开启 MCC接口的区域繁殖功能。 具体的， 网元 E8、 网元 E6各自开启相应 MCC接口区域繁殖功能。 具体的， 网元 E8开启 MCC5接口的区域繁殖功能、网元 E6开启 MCC8接口、 MCC11接口 的区域繁殖功能。网元 E6通过开启的繁殖功能接口自动发送区域繁殖请求报文给网 元 E7、 网元 E1， 并向网元 E5回送应答报文， 网元 E5收到的应答报文后， 对 其进行校验， 若确认域部署完成则关闭全局区域繁殖功能（见步骤 S240) ， 若域配置 信息校验不通过，则在关闭全局区域繁殖功能的同时还要以告警形式通知维护人员（见 步骤 S245 ) 。 由于网元 NE1校验到网元 E6发来的区域繁殖请求报文中的 ROUTER-ID为自己 ID, 网元 E1不做域配置修改， 直接回复应答报给网元 E6， 网元 E6关闭全局区 域繁殖功能； 由于网元 E6、网元 E8都会向网元 E7发送区域繁殖请求报文，后续网元 E7 基于收到的请求报文进行处理后会分别向网元 E8、 网元 E6回送应答报文， E8、 E6关闭各自的全局区域繁殖功能。当网元 E7再通过本端的开启了区域繁殖功能的 MCC接口向相应网元 （即网元 E8、 网元 E6) 发送区域繁殖请求报文时， 由于网 元 E8、 网元 E6全局区域繁殖功能被关闭， 网元 E8、 网元 E6直接回复应答报 文， 要求关闭 E7的全局区域繁殖功能， AREA2域内所有网元的区域信息自动配置 完成。 本网络还需要配置非骨干域 AREA3域内所有网元的区域信息， 开启网元 E3的 MCC21接口区域繁殖功能， 自动完成该区域内所有网元的区域信息配置。 至此， 图 9中所有非骨干域网元区域繁殖过程结束， 所有非骨干域网元域部署完 成。 应用实例二 在本应用实例中详细阐述图 10中 AREA2 AREA5中各网元区域繁殖过程， 图 10 中包含的网络场景有： 一个 ABR网元带 2个以上非骨干域， 如网元 NE1、 网元 E3; 两个 ABR 网元与同一个非骨干域相连， 如网元 E1、 网元 E2 都与非骨干域 AREA4相连； 非骨干区域为一个单链； 非骨干区域为一个闭环， 这种拓扑在应用实例一中已有阐述； 对现网进行扩容。 本应用实例的非骨干域繁殖流程如下： 第一步， 确定骨干区域， 为骨干区域内所有网元分配骨干域 MCC接口与非骨干 域 MCC接口， 分配骨干区域网元 E1 E4各 MCC接口区域。 以网元 E1为例， 网 元 E1的 MCC2接口、 MCC3接口与骨干域设备相连， 配置为代表骨干域的区域 ID: 0.0.0.0， MCC9接口、 MCC20接口均与 AREA2相连， 这两个 MCC接口配置为代表 非骨干域的区域 ID: 0.0.0.2， MCC36接口与 AREA4相连， 其接口的区域 ID设置为 0.0.0.4。 按此方法依次部署网元 E2 E4的各 MCC接口的区域 ID。 第二步， 开始繁殖 AREA2区域。 先开启网元 NE1的非骨干 MCC9接口下的区域 繁殖功能， 区域繁殖网元数量配置为无穷值， MCC9接口自动向其非骨干域邻居网元 E5发送区域繁殖请求报文， 载荷部分携带本 MCC接口的区域 ID、 本网元的区域类 型等信息。 第三步，网元 E5收到区域繁殖请求报文后，根据载荷信息修改网元上所有 MCC 接口区域 ID， 与载荷信息中的 MCC接口的区域 ID—致， 并开启除 MCC10接口外所 有 MCC接口的区域繁殖功能， 然后回送应答报文给网元 E1， 应答报文载荷内容为 网元 E5的域配置信息， 网元 E1收到应答报文后， 确认域部署完成则关闭全局区 域繁殖功能， 若域配置信息校验不通过， 则在关闭全局区域繁殖功能的同时还要以告 警形式通知维护人员； 网元 E5开启区域繁殖功能的 MCC接口向其下游邻居网元 E8、 E6发送区域 繁殖请求报文，请求报文载荷部分采用复制网元 NE1的 MCC接口下发出的请求报文 载荷内容。 网元 E8与网元 E6重复网元 E5的操作来完成 AREA2内所有网元的 区域繁殖。 该过程应用实例一完全一样。 第四步， 开始繁殖 AREA4区域。 由于 AREA4同时与 ABR网元 E1、 E2相连， 在繁殖 AREA4时， 需要先关闭 （可手动开启）其中一个 ABR网元的全局区域繁殖功 能， 此处关闭网元 E2的全局区域繁殖功能。 开启网元 NE1的 MCC36接口下的区域 繁殖功能， 由于网元 E1 曾经执行了区域繁殖操作， 所以此时需要检查网元 E1全 局区域繁殖功能是否已经关闭， 若被关闭， 需要将全局区域繁殖功能开启 （可手动开 启） ； MCC36接口向网元 E10发送区域繁殖请求报文， 网元 E10收到请求报文后 修改各 MCC接口的区域 ID为 0.0.0.4，即与 MCC36接口的区域 ID—致，开启 MCC30 接口的区域繁殖功能， 同时回送应答报文给网元 E1， 网元 E1收到应答报文后， 进 行相关校验后， 关闭区域繁殖功能。 第五步， 网元 E10的 MCC30接口向网元 E9发送请求报文， 网元 E9收到请 求报文后， 修改各 MCC接口的区域配置， 开启 MCC34接口的区域繁殖功能， 同时回 送应答报文给网元 E10, 网元 E10收到应答报文后， 进行相关校验后， 关闭全局区 域繁殖功能。 MCC34接口向网元 E2发送请求报文， 由于网元 E2全局区域繁殖功 能关闭， 网元 E2不对请求报文响应， 直接回复应答报文给网元 E9， 网元 E9收 到应答报文后关闭本网元的全局区域繁殖功能。 第六步， 开始繁殖 AREA3区域。 AREA3区域繁殖过程与 AREA2区域繁殖过程 相同。 第七步， 开始繁殖 AREA5区域。 检查网元 E3全局区域繁殖功能是否被关闭， 若被关闭， 需要开启 （可手动开启） 。 开启 MCC31接口的区域繁殖功能， MCC31向 网元 E14发送区域繁殖请求报文， 网元 E14收到请求报文后， 修改各 MCC接口的 区域配置， 开启 MCC33接口的区域繁殖功能， 同时回送应答报文给网元 E3， 网元 E3收到应答报文后， 进行相关校验后， 关闭区域繁殖功能。 第八步， 网元 E14的 MCC33接口向网元 E15发送请求报文， 网元 E15收到 请求报文后，修改各 MCC接口的区域 ID与 MCC33接口的区域 ID—致， 由于该网元 只有一个 MCC接口， 所以不需要开启其他 MCC接口的区域繁殖功能， 直接回送应答 报文给网元 E14, 网元 E14收到应答报文后，进行相关校验后，关闭区域繁殖功能。 另外， 在图 10中 AREA5中扩容网元区域繁殖过程， 如下： 第一步，将网元 NE16、网元 E17按规划网络拓扑与网元 E15间部署物理连接； 第二步， 开启网元 E14与网元 E15 的全局区域繁殖功能， 并开启网元 E14 的 MCC33接口的区域繁殖功能； 第三步，通过 MCC33接口向网元 E15发送请求报文，网元 E15修改所有 MCC 接口的区域 ID， 包括 MCC37接口、 MCC39接口的区域配置， 开启这两个 MCC接口 的区域繁殖功能， 这两个 MCC接口分别向网元 E17、 网元 E16发送请求报文； 网 元 E15回送应答报文， 网元 E14收到应答报文后进行相关处理； 第四步， 网元 E17、 网元 E16收到请求报文后修改各自所有 MCC接口的区域 ID, 并分别开启 MCC41接口、 MCC42接口区域繁殖功能， 分别向网元 E16、 网元 E17发送请求报文， 同时向网元 E15回送应答报文， 网元 E15关闭全局区域繁殖 功能， 即关闭了 MCC37接口、 MCC39接口的区域繁殖功能； 第五步， 网元 E16、 网元 E17收到对端的请求报文后， 修改域配置信息， 并互 相回复应答报文， 然后关闭自己的全局区域繁殖功能与 MCC接口区域繁殖功能， 区 域繁殖过程结束， 完成新入网设备的扩容。 至此附图 10中所有非骨干区域网元区域繁殖过程结束，所有非骨干域网元域部署 完成。 本发明实施例的所述实现非骨干区域自动繁殖的方法及相关设备， 提高了便捷开 通与即插即用场景下 PTN网络开通的效率，与相关技术中的只能通过人工方式去完成 区域部署操作的方法相比，节省了大量的人力财力成本，大大缩短网络开通所需时间， 提高了网络开通的效率及运营商满意度。 在背景技术中所举的例子， 人工操作需要约 7小时， 若采用自动繁殖的方法， 只需要在边界网元上开启 17个 MCC接口的区域繁 殖功能， 在这个过程中， 可以手动开启也可以自动开启， 即使采取手动开启， 假如开 启一个 MCC接口区域繁殖功能需要 30秒时间， 则完成 850个网元的区域划分部署也 才需要 8分钟左右的时间， 效率较人工操作提高了近 60倍，在网络规模越大的情况下 其优势越明显。 通过具体实施方式的说明， 应当可对本发明为达成预定目的所采取的技术手段及 功效得以更加深入且具体的了解， 然而所附图示仅是提供参考与说明之用， 并非用来 对本发明加以限制。 2) The function-enabled execution module 202 is configured to enable the area reproduction function of the remaining MCC interfaces except the MCC interface for receiving the propagation request message of the area, and send the area to the corresponding neighboring network element through the remaining MCC interfaces. The content of the payload of the area propagation request message sent by the propagation request packet is the same as the payload content of the area propagation request message received by the local network element. Meanwhile, the upstream neighbor network element sends a response report to the area that sends the request message. The payload content of the response packet is the current domain configuration information of the network element, and the content of the domain configuration information includes: an area ID of each MCC interface on the network element, and an area type of the local network element; 3) The response message processing module 203 is configured to: when receiving the response message sent by the downstream neighbor network element, disable the global area reproduction function of the local network element; and may be encountered for some network elements in the non-backbone domain. The design response message processing module 203 is further configured to directly reply the response message if the area reproduction request message is received when the global area reproduction function of the local network element is closed. Preferably, the response message processing module 203 is further configured to: when the response message is received, check the response message, and report the alarm when the domain deployment on the neighboring network element fails. For example, before the global area propagation function of the NE is disabled, the response packet is verified. When the domain deployment on the neighbor NE is completed, the global area propagation function of the NE is disabled. When the domain deployment on the neighboring NE fails, the global area propagation function of the NE is disabled and an alarm is reported to notify the maintenance personnel. In this embodiment, preferably, the payload part of the area propagation request message further includes: a quantity of the area breeding network element, configured to enable the user to control the number of the breeding network element, for example, for an already stable network, it may be only a part of the expansion. Equipment, you need to limit the number of breeding network elements at this time, to avoid affecting the regional configuration of the entire network. When the default value of the number of regional breeding network elements is set to 0, it is also a secure processing mechanism. In addition, the parameter setting of the number of breeding network elements in the area can also enable the user to limit the size of the non-backbone domain, that is, the number of network elements included in the non-backbone domain. For any network element in the non-backbone domain, the function opening execution module 202 is further configured to: when the area breeding request message is sent, the number of regional breeding network elements in the payload content of the area breeding request message is reduced by one, and the rest The payload content is the same as the payload content of the regional propagation request message received by the local network element. A tenth embodiment of the present invention is a non-backbone area automatic propagation system. The PTN network defines a backbone domain, and the MCC interface connected to the non-backbone domain on the border network element of the backbone domain is called a non-backbone domain MCC interface. Set the global area breeding function enabled by default for all NEs, and set the default area breeding function for all MCC interfaces. For any network element in any boundary or non-backbone domain, the global area reproduction function is disabled. The area breeding function of all the MCC interfaces on the network element cannot be enabled. The system includes: the boundary network element of the backbone domain and the network element in the non-backbone domain as described in the foregoing embodiments. . In order to better explain the objects, technical solutions and advantageous effects of the present invention, three embodiments of the present invention will be described below based on the above embodiments, with reference to FIGS. 8-10, and the implementation of the technical solutions of the present invention will be further described in detail. The area breeding requires maintenance personnel to first identify a backbone domain, and then allocate the area connected to the MCC interface of all network element devices in the backbone domain according to the networking plan, and then open the ABR (Area Border Router) NE in the backbone domain. The area breeding function of the MCC interface connected to the non-backbone domain, from the ABR network element (The boundary network element in the above embodiment) is automatically configured on all network elements in the non-backbone domain from near to far. The configuration process is performed hop by hop, and no human intervention is required in the whole process. The application example 1 illustrates the regional reproduction process by taking the E1 network element of the backbone domain in FIG. 9 as an example of the non-backbone domain AREA2 connected thereto. For a PTN device that supports the easy-to-open function, the DCN (Data Communication Network) function is enabled by default. When the physical port is connected and up, the DCN function automatically creates an MCC interface. Each MCC interface on a NE device is in the same domain by default. As shown in Figure 8, the non-backbone domain propagation process in this application example is as follows: In the first step, a backbone domain is determined, and the MCC interface of the backbone domain and the MCC interface of the non-backbone domain are assigned to all the NEs in the backbone domain. Step S201: Step S201 , backbone area deployment. Specifically, each MCC interface area is allocated to the backbone network element NE1 E4. The network element E1 is used as an example. The MCC13 interface and the MCC20 interface of the NE E1 are connected to the NEs in the backbone domain. The area ID of the two MCC interfaces is set to 0.0.0.0, which represents the backbone domain. The MCC12 interfaces are connected to the AREA2. The area IDs of the two MCC interfaces are configured to be 0.0.0.2, which represents the non-backbone domain. The area ID of each MCC interface of the NE E2 E4 is configured in this way. The second step is to enable the area breeding function of the non-backbone domain MCC interface of the ABR network element in the backbone network. The MCC interface that has enabled the area breeding function automatically sends a regional breeding request packet to the non-backbone neighbor network element connected to it. S205: Step S205, the area reproduction function of the MCC interface of the ABR network element is enabled. Specifically, the area breeding function of the non-backbone domain MCC interface of the NE NE1 is turned on. Since the MCC1 interface and the MCC12 interface are both connected to the same non-backbone domain, you only need to enable the regional breeding function under one of the MCC interfaces. For example, to open the area breeding function under the MCC1 interface, there is no need to control the number of breeding nodes in the area. The number of breeding nodes in the area needs to be configured as an infinite value. After the area breeding function is enabled, the MCC1 interface sends the neighboring network element E5. The area propagation request packet, the payload part carries information such as the area ID and the area type of the MCC interface, and the area type refers to the area type information specified in the OSPF protocol, which is not described in detail herein. In the third step, after receiving the area propagation request packet, the non-backbone neighbor network element first checks the ROUTER-ID of the packet, and then determines the area of each MCC interface of the network element according to the request packet. The area is propagated to all the MCC interfaces except the interface of the upstream network element, and the area propagation request packet is sent, and the response packet is sent back to the upstream network element. After receiving the response packet, the upstream NE disables the global area propagation function and the MCC interface area propagation function. Step decomposition is shown in steps S210, S215, S220, and S225. Step S210: The neighboring network element completes the domain configuration of the MCC interface. Specifically, after receiving the area propagation request packet, the network element E5 modifies the area ID of all MCC interfaces on the local network element to 0.0.0.2 according to the payload information. Step S215: The neighboring network element starts the area breeding function of the MCC interface. Specifically, the network element E5 enables the area reproduction function of all MCC interfaces except the MCC2 interface on the network element, that is, the area reproduction function of the MCC3 and MCC10 interfaces is automatically enabled. After the propagation function of the area is enabled, the network element E5 immediately sends a regional breeding request packet to the downstream neighboring network elements E8 and E6 through the MCC3 and MCC10 interfaces, and the request packet payload part is propagated by the area sent by the MCC1 interface of the replication network element E1. The payload content of the request message. At the same time, the network element E5 sends a response message to the network element E1, and the payload content of the response message is the domain configuration information of the network element E5. After receiving the response packet, the network element E1 verifies the response packet. If the domain configuration is confirmed, the global area propagation function is disabled (see step S230). If the domain configuration information is not verified, the global area reproduction function is disabled. At the same time, the maintenance personnel are notified in the form of an alarm (see step S235). In step S220, the downstream neighbor network element completes the domain configuration. Specifically, after receiving the area propagation request message of the network element E5, the network element E8 and the network element E6 modify the area ID of all MCC interfaces of the network element to be 0.0.0.2. Step S225, the downstream neighbor network element starts the area breeding function of the MCC interface. Specifically, the network element E8 and the network element E6 respectively activate the corresponding MCC interface area breeding function. Specifically, the network element E8 enables the area breeding function of the MCC5 interface, and the network element E6 enables the MCC8 interface and the MCC11 interface to perform regional breeding functions. The network element E6 automatically sends the area breeding request message to the network element E7 and the network element E1 through the open breeding function interface, and sends a response message to the network element E5. After receiving the response message, the network element E5 performs the calibration message. If the domain configuration is completed, the global area propagation function is disabled (see step S240). If the domain configuration information is not verified, the maintenance personnel should be notified by alarm when the global area reproduction function is disabled (see step S245). . The network element NE1 verifies that the ROUTER-ID in the area propagation request packet sent by the network element E6 is its own ID, and the network element E1 does not modify the domain configuration, and the direct reply response is reported to the network element E6, and the network element E6 is closed globally. The area breeding function; the network element E6 and the network element E8 will send the area breeding request message to the network element E7, and the subsequent network element E7 will send a response to the network element E8 and the network element E6 respectively after processing the received request message. Messages, E8, E6 close their respective global region breeding functions. When the network element E7 sends the area propagation request packet to the corresponding network element (that is, the network element E8 and the network element E6) through the MCC interface of the local area, the global area reproduction function is performed by the network element E8 and the network element E6. After being shut down, the network element E8 and the network element E6 directly reply to the response message, and the global area reproduction function of the E7 is required to be closed, and the area information of all the network elements in the AREA2 domain is automatically configured. The network also needs to configure the area information of all the NEs in the non-backbone domain AREA3 domain, and enable the MCC21 interface area breeding function of the NE E3 to automatically complete the area information configuration of all NEs in the area. At this point, the propagation process of all non-backbone domain NEs in Figure 9 ends, and all non-backbone domain NEs are deployed. Application Example 2 In this application example, the propagation process of each network element area in AREA2 AREA5 in FIG. 10 is elaborated. The network scenario included in FIG. 10 is as follows: One ABR network element has more than two non-backbone domains, such as network element NE1. Element A3; two ABR network elements are connected to the same non-backbone domain, for example, network element E1 and network element E2 are connected to non-backbone area AREA4; non-backbone area is a single chain; non-backbone area is a closed loop, this topology It has been explained in Application Example 1; expansion of the existing network. The non-backbone domain propagation process in this application example is as follows: In the first step, the backbone area is determined. The MCC interface of the backbone domain and the MCC interface of the non-backbone domain are assigned to all the NEs in the backbone area, and the MCC interface areas of the NEs E1 E4 in the backbone area are allocated. The network element E1 is used as an example. The MCC2 interface and the MCC3 interface of the NE E1 are connected to the backbone domain device and are configured to represent the area ID of the backbone domain: The 0.0.0.0, MCC9 interface and MCC20 interface are connected to AREA2. The two MCC interfaces are configured to represent the area ID of the non-backbone domain: 0.0.0.2. The MCC36 interface is connected to AREA4, and the area ID of the interface is set to 0.0.0.4. The area ID of each MCC interface of the NE E2 E4 is deployed in this way. The second step is to start breeding the AREA2 area. The area propagation function is enabled on the non-backbone MCC9 interface of NE1. The number of regional propagation NEs is infinite. The MCC9 interface automatically sends the area breeding request packet to the non-backbone neighbor NE. The payload part carries the MCC. Information such as the area ID of the interface and the area type of the NE. In the third step, after receiving the area propagation request packet, the network element E5 modifies all MCC interface area IDs on the network element according to the load information, and the area ID of the MCC interface in the payload information, and enables all MCCs except the MCC10 interface. The area propagation function of the interface, and then the response packet is sent back to the network element E1. The payload of the response packet is the domain configuration information of the network element E5. After receiving the response packet, the network element E1 confirms that the domain deployment is complete, and the global area reproduction function is disabled. If the domain configuration information is not verified, the maintenance personnel are notified by the alarm mode while the global area propagation function is disabled. The network element E5 enables the MCC interface of the area breeding function to send the area to the downstream neighbor network elements E8 and E6. Request packet, the request packet payload part uses the payload of the request message sent by the MCC interface of the replication NE NE1. The network element E8 and the network element E6 repeat the operation of the network element E5 to complete the area reproduction of all network elements in the AREA2. The process application example is exactly the same. The fourth step begins to breed the AREA4 region. Since the AREA4 is connected to the ABR network elements E1 and E2 at the same time, when the AREA4 is propagated, the global area reproduction function of one of the ABR network elements needs to be turned off (manually enabled), and the global area reproduction function of the network element E2 is turned off. Enable the area breeding function on the MCC36 interface of the NE1. Since the NE E1 has performed the area breeding operation, you need to check whether the global area breeding function of the NE E1 is closed. If it is disabled, you need to reproduce the global area. On the MCC36 interface, the MCC36 interface sends the area propagation request packet to the network element E10. After receiving the request packet, the network element E10 modifies the area ID of each MCC interface to 0.0.0.4, that is, the area ID of the interface with the MCC36. The area propagation function of the MCC30 interface is enabled, and the response packet is sent back to the network element E1. After receiving the response message, the network element E1 performs the correlation check and then disables the area reproduction function. In the fifth step, the MCC30 interface of the network element E10 sends a request message to the network element E9. After receiving the request message, the network element E9 modifies the area configuration of each MCC interface, enables the area reproduction function of the MCC34 interface, and sends back the response message. After receiving the response packet, the network element E10 and the network element E10 perform the correlation check and then disable the global area reproduction function. The MCC34 interface sends a request packet to the network element E2, because the network element E2 global region reproduces work. The network element E2 does not respond to the request packet, and directly responds to the response packet to the network element E9. After receiving the response packet, the network element E9 disables the global area reproduction function of the network element. In the sixth step, the AREA3 area is propagated. The reproductive process of the AREA3 region is the same as that of the AREA2 region. The seventh step begins to breed the AREA5 region. Check whether the global area propagation function of the NE E3 is disabled. If it is turned off, it needs to be turned on (can be manually turned on). After the area propagation function of the MCC31 interface is enabled, the MCC31 sends a regional breeding request packet to the network element E14. After receiving the request packet, the network element E14 modifies the regional configuration of each MCC interface, and then enables the regional breeding function of the MCC33 interface, and sends back the response report. After the message is sent to the network element E3 and the network element E3 receives the response message, the area is propagated after the correlation check is performed. In the eighth step, the MCC33 interface of the network element E14 sends a request message to the network element E15. After receiving the request message, the network element E15 modifies the area ID of each MCC interface and the area ID of the interface of the MCC33, because the network element only has An MCC interface does not need to enable the area propagation function of other MCC interfaces, and directly sends a response packet to the network element E14. After receiving the response message, the network element E14 performs the correlation check and then disables the area reproduction function. In addition, in FIG. 10, the propagation process of the network element area in the AREA5 is as follows: In the first step, the network element NE16 and the network element E17 are physically connected to the network element E15 according to the planned network topology; and the second step is to open the network element E14. The global area propagation function of the network element E15 is enabled, and the area propagation function of the MCC33 interface of the network element E14 is enabled. The third step is to send a request packet to the network element E15 through the MCC33 interface, and the network element E15 modifies the area ID of all the MCC interfaces. The area configuration of the MCC37 interface and the MCC39 interface is enabled to enable the area propagation function of the two MCC interfaces. The two MCC interfaces send request packets to the network element E17 and the network element E16 respectively. The network element E15 sends a response packet to the network element. E14 receives the response packet and performs related processing. In the fourth step, the network element E17 and the network element E16 modify the area ID of each MCC interface after receiving the request message, and respectively enable the MCC41 interface and the MCC42 interface area to reproduce the functions respectively. The request message is sent to the network element E16 and the network element E17, and the response message is sent back to the network element E15. The network element E15 disables the global area reproduction function, that is, the MCC37 interface and the MCC39 interface area are closed. The fifth step, after receiving the request message from the peer, the network element E16 and the network element E17 modify the domain configuration information, and reply the response message to each other, and then close the global area breeding function and the MCC interface area breeding function. The regional breeding process is completed, and the expansion of the new network access equipment is completed. As shown in Figure 10, the propagation process of all non-backbone area network element areas is completed, and all non-backbone area network element domains are deployed. The method for realizing non-backbone area automatic breeding and related equipment in the embodiment of the present invention improves the efficiency of opening a PTN network in a convenient opening and plug-and-play scenario, and the related technology can only complete the regional deployment by manual means. Compared with the operation method, it saves a lot of human and financial costs, greatly shortens the time required for network opening, and improves the efficiency of network opening and operator satisfaction. In the example given in the background, the manual operation takes about 7 hours. If the automatic breeding method is adopted, only the regional reproduction function of 17 MCC interfaces needs to be opened on the border network element, and in this process, it can be manually turned on or Automatically, even if manual opening is required, if it takes 30 seconds to open an MCC interface area reproduction function, it takes about 8 minutes to complete the 850 network element area division deployment, and the efficiency is nearly 60 times higher than the manual operation. The advantage is greater when the network size is larger. The technical means and functions of the present invention for achieving the intended purpose can be more deeply and specifically understood by the description of the specific embodiments. However, the accompanying drawings are only for the purpose of illustration and description, and are not intended to limit.
