  • Step 1002 The normal node receives the service rejection message, and sends a network management service node request message to the proxy selection server.

  • Step 1005 The proxy selection server receives the network management service request response message, and returns a network management service node response message to the normal node, where the message carries the network management service node information.
  • Step 1006 The ordinary node receives the network management service node response message, and sends a service request message to the network management service node.
  • Step 1007 The network management service node receives the service request message, and determines whether it should be handed over to the secondary network management server according to the urgency degree of the service. If yes, go to step 1008; otherwise, go to step 1009.

Unstable factors in the network may cause the network management service node to exit the network abnormally. In this case, a new network management service node needs to take over its work, which is mainly guided by the agent selection server. The exit of the same network management service node is also divided into graceful and ungraceful cases. The following examples are given for each of these two cases:

通常, 代理选择服务器会将与普通节点位于同一区域内的网管代理节 点返回给该普通节点。
步骤 603 : 普通节点接收网管代理节点查询响应消息, 从网管代理节 点列表中选择一个网管代理节点, 向该网管代理节点发送代理请求消息。
步骤 604: 网管代理节点接收该代理请求消息, 向普通节点返回代理 响应消息。
步骤 605 : 普通节点接收代理响应消息, 通过网管代理节点向二级网 管服务器发送连接请求消息。
步骤 606: 二级网管服务器接收该连接请求消息, 向网管代理节点返 回连接响应消息, 网管代理节点接收该连接响应消息, 将该连接响应消息 转发给普通节点, 普通节点接收该连接响应消息。
至此, 普通节点与二级网管服务器之间通过网管代理节点重新建立连 接。 图 7为本发明实施例二提供的当二级网管服务器与普通节点之间不可 直接到达时, 由二级网管服务器主动发起的建立连接的方法的消息流程图, 如图 7所示, 其具体步骤如下:
步骤 701 : 二级网管服务器发现一普通节点不可直接到达, 向代理选 择服务器发送网管代理节点查询消息。
步骤 702: 代理选择服务器接收网管代理节点查询消息, 向网管服务 器返回网管代理节点查询响应消息, 该消息携带网管代理节点列表。
通常, 代理选择服务器会将与二级网管服务器位于同一区域内的网管 代理节点返回给该二级网管服务器。
步骤 703 : 二级网管服务器接收该网管代理节点查询响应消息, 从网 管代理节点列表中选择一个网管代理节点, 向该网管代理节点发送代理请 求消息。
步骤 704: 网管代理节点接收该代理请求消息, 向二级网管服务器返 回代理响应消息。
步骤 705 : 二级网管服务器接收代理响应消息, 通过网管代理节点向 普通节点发送连接请求消息。
步骤 706: 普通节点接收该连接请求消息, 通过网管代理节点向二级 网管服务器返回连接响应消息, 二级网管服务器接收该连接响应消息。
至此, 二级网管服务器与普通节点之间通过网管代理节点重新建立连 接。 网络中含有不稳定的因素, 因此网管代理节点可能随时发生问题退出 网络, 当网管代理节点退出网络后需要立即有新的网管代理节点接替其工 作, 以下给出具体解决方案。
网管代理节点的退出分为两种情况: 优雅 (graceful ) 退出和不优雅
( ungraceful ) 退出, 区别在于: 前者在退出前给网管服务器和其它节点发 送退出消息, 而后者则不进行该动作。 以下针对这两种情况分别给出实施 例:
图 8为本发明实施例一提供的网管代理节点 graceful退出时, 产生新 的网管代理节点的方法的消息流程图, 如图 8所示, 其具体步骤如下: 步骤 801 : 网管代理节点要 graceful退出时, 向代理选择服务器和自身 所服务的普通节点发送退出消息。
步骤 802: 代理选择服务器接收该退出消息, 将自身记录的该网管代 理节点的状态更改为退出, 并向该网管代理节点返回退出响应消息; 各普 通节点接收该退出消息, 向该网管代理节点返回退出响应消息。
步骤 803 : 网管代理节点接收到代理选择服务器和各普通节点返回的 退出响应消息, 退出网络。
步骤 804: 代理选择服务器向该原网管代理节点所服务的各普通节点 发送网管代理节点接替消息, 该消息携带网管代理节点接替指示信息, 同 时携带新网管代理节点信息。
步骤 805 : 各普通节点接收网管代理节点接替消息, 记录新网管代理 节点信息, 并向代理选择服务器返回网管代理节点接替响应消息, 同时向 新网管代理节点发送代理请求消息。
步骤 806: 新网管代理节点接收到任一普通节点发来的代理请求消息, 向该节点返回代理响应消息。
步骤 807: 普通节点接收代理响应消息, 通过新网管代理节点向二级 网管服务器发送连接请求消息。
步骤 808: 二级网管服务器接收连接请求消息, 通过新网管代理节点 向普通节点返回连接响应消息, 普通节点接收该连接响应消息。 至此, 网管代理节点接替流程完成。 图 9为本发明实施例二提供的网管代理节点 ungraceful退出时, 产生 新的网管代理节点的方法的消息流程图, 在本实施例中, 网管代理节点 ungraceful退出, 即退出时不通知任何节点,如图 9所示,其具体步骤如下: 步骤 901 : 普通节点向网管代理节点发送信息, 但是在预设响应时长 内未收到网管代理节点返回的响应消息, 则确定网管代理节点发生异常。
步骤 902: 普通节点向代理选择服务器发送新网管代理节点申请消息。 步骤 903 : 代理选择服务器接收新网管代理节点申请消息, 向普通节 点返回新网管代理节点信息。
步骤 904: 普通节点接收新网管代理节点信息, 向新网管代理节点发 送代理请求消息。
步骤 905 : 新网管代理节点接收普通节点发来的代理请求消息, 向普 通节点返回代理响应消息。
步骤 906: 普通节点接收代理响应消息, 通过新网管代理节点向二级 网管服务器发送连接请求消息。
步骤 907: 二级网管服务器接收该连接请求消息, 通过新网管代理节 点向普通节点返回连接响应消息, 普通节点接收该连接响应消息。
至此, 网管代理节点接替流程完成。 由于网管服务器要管理所有的节点, 因此, 当节点过多时, 网管服务 器的负载会过高, 从而影响网管服务器的性能。 为了解决该问题, 给出如 下解决方案。
图 10 为本发明实施例提供的对网管服务器进行负载分担的方法的消 息流程图, 如图 10所示, 其具体步骤如下:
步骤 1001 : 网管服务器发现自身处于超负载状态, 当此后接收到普通 节点发来的服务请求消息时, 向普通节点返回服务拒绝消息。
步骤 1002: 普通节点接收该服务拒绝消息, 向代理选择服务器发送网 管服务节点请求消息。 步骤 1003 : 代理选择服务器接收该网管服务节点请求消息, 选择一个 节点作为网管服务节点, 向该网管服务节点发送网管服务申请消息。
代理选择服务器通常根据如下条件来选择网管服务节点:
一、 在线时长能够保证;
二、 具备网管服务器的所有功能;
三、 具有公网 IP地址;
四、 处理能力较强。
步骤 1004: 网管服务节点接收网管服务申请消息, 向代理选择服务器 返回网管服务申请响应消息。
步骤 1005: 代理选择服务器接收网管服务申请响应消息, 向普通节点 返回网管服务节点响应消息, 该消息携带该网管服务节点信息。
步骤 1006: 普通节点接收网管服务节点响应消息, 向网管服务节点发 送服务请求消息。
步骤 1007: 网管服务节点接收该服务请求消息, 根据该服务的紧急程 度判断是否应交给二级网管服务器处理, 若是, 执行步骤 1008; 否则, 执 行步骤 1009。
步骤 1008: 网管服务节点将该服务请求消息转发给二级网管服务器, 二级网管服务器处理完毕, 向普通节点返回服务器响应消息, 本流程结束。
步骤 1009: 网管服务节点处理该服务请求消息, 处理完毕, 向普通节 点返回服务响应消息。 网络中的不稳定因素可能导致网管服务节点发生异常退出网络, 这时 需要一个新的网管服务节点接替其工作, 这主要是由代理选择服务器指导 完成的。 同样网管服务节点的退出也分为 graceful和 ungraceful两种情况。 以下针对这两种情况分别给出实施例:
图 11为本发明实施例一提供的网管服务节点 graceful退出时, 产生新 的网管服务节点的方法的消息流程图, 如图 11所示, 其具体步骤如下: 步骤 1101 : 网管服务节点要 graceful退出时, 向代理选择服务器和自 身所服务的普通节点发送退出消息。 步骤 1102: 代理选择服务器接收该退出消息, 将自身记录的该网管服 务节点的状态更改为退出, 并向该网管服务节点返回退出响应消息; 各普 通节点接收该退出消息, 向该网管服务节点返回退出响应消息。
步骤 1103 : 网管服务节点接收到代理选择服务器和各普通节点返回的 退出响应消息, 退出网络。
步骤 1104: 代理选择服务器向该原网管服务节点所服务的各普通节点 发送网管服务节点接替消息, 该消息携带网管服务节点接替指示信息, 同 时携带新网管服务节点信息。
步骤 1105: 各普通节点接收网管服务节点接替消息, 记录新网管服务 节点信息, 并向代理选择服务器返回网管服务节点接替响应消息, 同时向 新网管服务节点发送服务请求消息。
步骤 1106:新网管服务节点接收到任一普通节点发来的服务请求消息, 向该节点返回服务响应消息, 普通节点接收该服务响应消息。
至此, 网管服务节点接替流程完成。 图 12为本发明实施例二提供的网管服务节点 ungraceful退出时, 产生 新的网管服务节点的方法的消息流程图, 在本实施例中, 网管服务节点 ungraceful退出, 即退出时不通知任何节点, 如图 12所示, 其具体步骤如 下:
步骤 1201 : 普通节点向网管服务节点发送服务请求消息, 但是在预设 响应时长内未收到网管服务节点返回的服务响应消息, 则确定网管服务节 点发生异常。
步骤 1202:普通节点向代理选择服务器发送新网管服务节点申请消息。 步骤 1203 : 代理选择服务器接收新网管服务节点申请消息, 向普通节 点返回新网管服务节点信息。
步骤 1204: 普通节点接收新网管服务节点信息, 向新网管服务节点发 送服务请求消息。
步骤 1205: 新网管服务节点接收普通节点发来的服务请求消息, 向普 通节点返回服务响应消息, 普通节点接收该服务响应消息。 至此, 网管服务节点接替流程完成。
以上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在 本发明的精神和原则之内, 所做的任何修改、 等同替换、 改进等, 均应包 含在本发明保护的范围之内。
