- the upgrade management system can issue an upgrade instruction to the first node.
- the first node determines whether it needs to be upgraded. When the first node does not need to be upgraded, S204 is performed; when the first node needs to be upgraded, S203 is performed. The first node determines whether it needs to be upgraded according to the criteria set by the user. If it needs to be upgraded, it executes S203; if it does not need to be upgraded, the first node does not upgrade.
- the upgrade standard set by the administrator is to automatically connect to the Microsoft official website to detect whether the system patch of Windows Server 2008 is updated at 8:00 am every Monday. If the system patch is detected, the version number is higher than the installed patch in the server. For the version number, perform the upgrade procedure according to S2032. If the version number of the system patch is not higher than the patch version number installed in the server, the upgrade step is not performed.
- the first node upgrades according to the upgrade package and saves the upgrade package.
- the method for upgrading the node may include the following steps:
- the first node determines whether the load of the first node is allowed to be upgraded. If the load allows the first node to upgrade, execute S2032; if the load does not allow the first node to upgrade, execute S2031 again until the load of the first node is allowed to be upgraded, and execute and execute S2032.
- the first node downloads the upgrade package, upgrades according to the upgrade package, and saves the upgrade package.
- the first node divides all adjacent nodes of the first node into one or more upgrade groups. Specifically, there are several implementation methods:
- the head node can divide each of its neighbor nodes into a group. For example, suppose that there are 10 nodes in the network from 1 to 10, where node 1 is the first node, nodes 2 to 9 are adjacent nodes of node 1, and are directly connected to node 1, and node 10 is the adjacent node of node 5, as shown in the figure. 3 is shown. According to the above method, each of the nodes 2 to 9 can be divided into one group, and a total of 8 groups are obtained, and the nodes 10 are not grouped.
- the second method includes:
- the first node shields all the adjacent nodes of the first node and the first node in the topology map. Links between.
- the first node divides the node with the largest number of links among all adjacent nodes and the adjacent node of the node with the largest number of links into one upgrade group, and determines the priority upgrade queue of the group, wherein the number of links is the largest.
- the node is the first node of the upgrade group
- the priority upgrade queue is the upgrade sequence of the remaining nodes of the upgrade group after the upgrade of the first node of the upgrade group. If the remaining nodes except the grouped nodes are isolated nodes, the first node divides each of the isolated nodes into a group.
- the node with the largest number of links among the remaining nodes except the grouped node and the neighboring node of the node with the largest number of links among the remaining nodes are divided into An upgrade group, and determine the priority upgrade queue of the upgrade group, until all the neighbor nodes of the first node except the grouped node are isolated nodes, and each of the remaining isolated nodes is divided into an upgrade. group.
- the 10 nodes may first mask the link between the node 1 and the adjacent node of the node 1, that is, the link between the node 1 and the node 2 to the node 9, and block the result of the link.
- the node with the largest number of links after the link between the node 1 and the adjacent node of the node 1 is masked is selected, and the node 4, the node 2, the node 5, the node 6, and the node 4 and the node are selected.
- the adjacent nodes of 4 are divided into one group, that is, node 4, node 3, node 5, and node 6 are divided into one group, labeled as group A, and then all nodes in group A are shielded, and the result after deletion is shown in FIG. 5, and then The nodes with the most links among the remaining nodes, namely node 8 and node 9, are grouped into one group, which is marked as group B, so that the remaining isolated nodes 2 and 7 each constitute a group, and are marked as group C and group D due to Node 10 is not directly connected to node 1, so there is no packet of node 10 here.
- a data mining algorithm such as a K-means algorithm
- a typical distance-based clustering algorithm may be used according to actual requirements. Not limited.
- the first node sends a second upgrade instruction and a priority upgrade queue of the upgrade group to the first node in each upgrade group. Specifically, after the grouping is completed, the head node may be in accordance with the priority order of each upgrade group. And sending the second upgrade instruction and the priority upgrade queue of the upgrade group to the first node in each upgrade group.
- the priority here may be automatically determined according to the time sequence of generating the packet, that is, the first generated packet has the highest priority, and the last generated packet has the lowest priority. Of course, other methods may be used to determine the priority of each group. For example, by determining the number of nodes in the upgrade group, a large number of upgrade groups have a high priority to speed up the upgrade, and the present invention is not limited thereto.
- the first node of each upgrade group upgrades the nodes in the upgrade group according to the second upgrade instruction and the priority upgrade queue of the upgrade group. After receiving the second upgrade command sent by the first node, the first node of each upgrade group determines whether it needs to be upgraded. If the upgrade is required, the first node downloads the upgrade from the first node according to the second upgrade command. The package is upgraded, and the upgrade package is saved. The first node sends a third upgrade instruction to the other nodes in the upgrade group according to the received priority upgrade queue of the upgrade group according to the second upgrade instruction, so that other nodes can The upgrade instructions received are upgraded.
- each node except the first node After each node except the first node upgrades itself, it scans its neighbor nodes and upgrades the nodes that need to be upgraded in its neighbor nodes. Specifically, each node except the first node is upgraded according to the received subsequent upgrade instruction, where the subsequent upgrade instruction refers to a second upgrade instruction that is sent by the first node to the first node in each upgrade group, and each first The third upgrade instruction sent by the node to the other nodes in the upgrade group, and the upgrade instruction sent by each node to the fourth upgrade instruction of the other nodes in the searched neighboring nodes that need to be upgraded; After each node has been upgraded, it scans its neighbors and obtains the upgrade status of its neighbors. It sends a fourth upgrade command to the node that needs to be upgraded according to the upgrade status of its neighbors. The node is upgraded according to the fourth upgrade instruction.
- each node except the first node can first determine whether it needs to be upgraded.
- it sends the subsequent upgrade command to its previous node to obtain the upgrade package, and according to The load of the own determines whether the upgrade condition is met.
- the upgrade condition is met, the upgrade is performed according to the subsequent upgrade instructions, and the upgrade package is saved. If the upgrade condition is not met, the upgrade condition is determined again. After the upgrade condition is met, the upgrade is performed according to the received subsequent upgrade command, and the save is obtained. Upgrade package.
- the first node in the group with the highest priority is the node that needs to be upgraded, which is referred to as the current node.
- the current node After the current node receives the upper-level node, that is, the upgrade command sent by the first node and the upgrade queue of the group node, the current node determines whether it has been upgraded. When the current node has been upgraded, the current node scans its neighboring nodes to obtain the upgrade status of its neighboring nodes. Then, the current node sends a third upgrade command to its neighbors according to the priority upgrade queue of the node, so that the current node is adjacency. The point is upgraded according to the priority upgrade queue and the upgrade package of the node. If the current node needs to be upgraded, the current node obtains the upgrade package from the previous node, that is, the first node.
- the current node determines whether the upgrade condition is met according to its own load; if the upgrade condition is met, the current node upgrades according to the upgrade package and saves the upgrade package; if the current node does not meet the upgrade condition, the current node determines whether the upgrade condition is met again. Until the current node meets the upgrade conditions and upgrades according to the upgrade package, and saves the upgrade package. After the upgrade is completed, the current node needs to report its previous node, which refers to the first node. After the current node completes the upgrade, the third upgrade instruction is sent to the next node specified in the node's upgrade queue, so that the next node performs the upgrade, and the current node also scans its neighbor node to find its neighbor node. The node that needs to be upgraded, and sends a fourth upgrade instruction to the node that needs to be upgraded in its neighboring node, so that the nodes that need to be upgraded are upgraded.
- Each node that receives the third upgrade command or the fourth upgrade command scans its neighbor nodes after completing its own upgrade, finds the nodes that need to be upgraded in its neighbor nodes, and needs to upgrade to its own neighbor nodes.
- the node sends a fourth upgrade command to upgrade the nodes that need to be upgraded.
- the first node After all the nodes in the group with the highest priority are upgraded, the first node sends a second upgrade command and a priority upgrade queue of the node to the first node of the second highest priority group, so that the nodes in the group are followed.
- the priority upgrade queue of the node is upgraded.
- the method is the same as that of the node in the highest priority group, and is not mentioned here.
- nodes 1 there are 10 nodes in the network from 1 to 10, wherein node 1 is the first node, nodes 2 to 9 are adjacent nodes of node 1, and are directly connected to node 1, and node 10 is the adjacent node of node 5.
- the first grouping method in S204 is used for grouping, it is divided into 8 groups, and each group has one node, which is node 2 to node 9, respectively, and node 10 is not grouped.
- Node 1 first sends an upgrade command to the first group, that is, first upgrades node 2, and node 2 reports to node 1 after completing the upgrade, node 1 sends an upgrade command to the second group, that is, upgrade node 3, and node 2 scans to its neighbor.
- the node 6 needs to be upgraded, so the node 2 sends an upgrade command to the node 6, and the node 6 is also upgraded.
- the node 3 and the node 6 are simultaneously upgraded, and the node 3 is reported to the node 1 after the upgrade is completed, and the node 6 is upgraded. It is not a task that is sent by the node 1. Therefore, after the node 6 is upgraded, it is not reported to the node 1, but is reported to the node 2, and of course, it can be reported by the node 2 to the node node 1 again. Then node 1 sends an upgrade command to the third group, that is, upgrades node 4, and node 6 scans to its neighbor node 7 after upgrading to complete the upgrade, so node 6 sends an upgrade command to node 7, and node 7 is also upgraded.
- the node 4 and the node 7 are upgraded at the same time, and the node 4 is reported to the node 1 after the upgrade is completed, and since the node 7 is not upgraded by the node 1, the node 7 does not report to the node 1 after the upgrade. However, it is reported to the node 6, and can also be reported by the node 6 to the node node 2 to the upper node. Then, node 1 sends an upgrade command to the fourth group, that is, upgrades node 5, and node 5 reports to node 1 after completing the upgrade, and node 1 finds that node 5 of the fifth group and node 7 of the sixth group have been upgraded. In this case, the node may receive the related upgrade situation information obtained by the step-by-step reporting of each node.
- the node 1 may scan the neighboring node to obtain the related upgrade information, or the node 1 to the fifth group.
- the node 7 and the node 7 of the sixth group send the upgrade command, it is found that the nodes 6, 7 have completed the upgrade, and the present invention is not limited thereto. Therefore, the node 1 sends an upgrade command to the seventh group, that is, upgrades the node 8, and after the node 5 needs to be upgraded after scanning to the neighboring node 10, the node 5 sends an upgrade command to the node 10 to upgrade the node 10, thus implementing the node 8 and the node.
- node 8 is reported to the node 1 after the upgrade is completed, and since the node 10 is not upgraded by the node 1, the node 10 is not reported to the node 1 after the upgrade.
- node 1 sends an upgrade command to the eighth group to upgrade node 9. This completes the upgrade of all nodes. It can be seen that Node 3 and Node 6, Node 4 and Node 7, Node 8 and Node 10 are upgraded at the same time, saving upgrade time.
- group A includes: node 4, node 3, node 5, and node 6, group B includes node 8, node 9, and node C 2, group D includes node 7, and group E includes node 10.

具体实施方式 下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案 进行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实 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 人员在没有作出创造性劳动前提下所获得的所有其他实施例, 都属于本 发明保护的范围。 本发明实施例提供一种升级方法, 如图 1所示, 该方法包括:
5101、 首节点接收第一升级指令。 具体的, 该首节点可以是所有节点中的任意一个节点, 可以采用随 机方式或按照配置在各个节点中指定一个首节点, 也可以由系统自动或 人工来进行选取, 可以采用现有方法来指定, 本发明对此并不限制。 而 后, 首节点接收升级指令。
5102、 若首节点需要升级, 首节点根据第一升级指令下载升级包进 行升级, 并保存升级包。
具体的,首节点在接收到第一升级指令首先判断自身是否已经升级, 若升级则直接执行 S 103 ; 若首节点需要升级, 则下载升级包进行升级, 并保存升级包。
5103、 首节点将首节点的所有邻接节点分为一个或多个升级组。
5104、 首节点向每个升级组中的第一节点发送第二升级指令及本升 级组的优先升级队列, 以使第一节点根据第二升级指令及优先升级队列
对本升级组中的节点进行升级。
S 105、 每个升级组中的第一节点根据第二升级指令及本升级组的优 先升级队列对本升级组中的节点进行升级。
S 106、 除首节点外的每个节点在自身已升级后, 对自身的邻接节点 进行扫描, 并将自身的邻接节点中需要升级的节点根据升级包进行升级。 示例性的, 在完成分组后, 按照各组的优先级由高到低地将各组进 行逐组升级, 每个组在升级组内的节点时也要按照节点的优先级由高到 低地进行逐点升级。 需要说明的是, 这里的优先级可以是按照生成分组 的时间先后自动决定的, 即首先生成的分组具有最高的优先级, 最后生 成的分组具有最低的优先级, 当然也可以采用其他的方法确定各组的优 先级, 例如, 通过升级组中节点的数量来确定, 数量多的升级组优先级 高, 以加快升级的速度, 本发明对此并不限制。 组内每个节点在完成升 级后还要扫描自身的邻接节点, 并将邻接节点中需要升级的节点进行升 级, 这样就实现了多个节点的并行升级。 并且, 除首节点外的每个节点 在自身已升级后, 都会对自身的邻接节点进行扫描, 并将自身的邻接节 点中需要升级的节点根据升级包进行升级。 而且, 每个节点在升级完成 后都会保存升级包, 以便在下一个节点升级时将该升级包传给下一个节 点, 因此, 各节点只需要和首节点存在通路就可以完成升级。 其中, 上 述节点可以是服务器。 本发明的实施例提供一种升级的方法, 在需要升级的节点网络中, 首节点在接收到升级指令后, 将自身的相邻节点分组, 并向各分组的第 一个节点下达升级指令和优先升级列表, 各分组的第一个节点根据升级 指令优先升级列表将组内节点升级, 除首节点外的节点在自身升级后要 扫描与其相连的节点升级情况并对需要升级节点进行升级, 被升级节点 只需要和初始升级节点存在通路就可以完成升级, 从而提高了升级的成 功率, 而且实现了多个节点并行升级, 提高了升级效率。 本发明另一实施例提供一种升级的方法, 如图 2所示, 该方法包括:
S201、 首节点接收第一升级指令。 其中, 选择首节点可以由升级管理系统来完成, 具体的, 可以采用 随机方式或按照配置或由人工选取的方法在各个节点中指定一个首节
点, 这里升级管理系统可以是一个软件平台并运行在一种节点设备中, 该设备可以是一种嵌入式设备, 网络可以指局域网, 节点可以是服务器。 例如, 在数据中心的网络中, 有多台服务器需要升级软件或者固件, 该 数据中心的网络可以选择任意一台服务器作为升级的首节点。 在确定首 节点后, 升级管理系统就可以向该首节点下发升级指令。
5202、 首节点在接收第一升级指令后, 首节点判断自身是否需要升 级,当首节点不需要升级时,执行 S204;当首节点需要升级时,执行 S203。 首节点根据用户设定的标准判断自身是否需要升级,如果需要升级, 则执行 S203 ; 如果不需要升级, 则首节点不进行升级。 示例性的, 假设管理员设定的升级标准为在每周一上午 8点自动连 接 Microsoft官网检测 Windows Server 2008的系统补丁有无更新, 如果 检测到系统补丁的版本号高于服务器中已安装的补丁版本号, 则按照执 行 S2032进行升级步骤, 如果检测到系统补丁的版本号不高于服务器中 已安装的补丁版本号, 则不执行升级步骤。
5203、 首节点根据升级包进行升级并保存该升级包。 具体的, 节点 升级的方法可以包括以下步骤:
52031 , 首节点判断自身的负载是否允许升级, 如果负载允许首节点 升级, 则执行 S2032; 如果负载不允许首节点升级, 则再次执行 S2031 , 直至首节点的负载允许升级时为止, 并执行则执行 S2032。
52032、 首节点下载升级包, 根据升级包进行升级, 并保存升级包。
5204、 首节点将首节点的所有邻接节点分为一个或多个升级组。 具体的, 可以有以下几种实现方法:
第一种, 首节点可以将自身的每一个邻接节点分为一个组。 例如, 假设网络中有 1〜10共 10个节点, 其中节点 1为首节点, 节点 2〜节点 9 为节点 1的邻接节点, 与节点 1直接相连, 而节点 10为节点 5的邻接节 点, 如图 3所示。 根据上述方法可以将节点 2〜节点 9中每个节点分为一 组, 共得到 8个组, 而节点 10不分组。
或者, 第二种方法包括:
第一步, 首节点在拓朴图中屏蔽首节点与首节点的所有邻接节点之
间的链接。
第二步, 在屏蔽链接之后, 首节点将所有邻接节点中链接数目最多 的节点与链接数目最多的节点的邻接节点分为一个升级组, 并确定该组 的优先升级队列, 其中, 链接数目最多的节点为该升级组的第一节点, 优先升级队列为在该升级组的第一节点完成升级后, 该升级组其余节点 的升级顺序。 若除已分组节点外的剩余节点都为孤立节点, 则令首节点把每个孤 立节点分为一个组。 若首节点的所有邻接节点中除已分组节点外的剩余节点存在非孤立 节点, 则将除已分组节点外的剩余节点中链接数目最多的节点与剩余节 点中链接数目最多的节点的邻接节点分为一个升级组, 并确定该升级组 的优先升级队列, 直至首节点的所有邻接节点中除已分组节点外的剩余 节点都为孤立节点为止, 并将剩余的每个孤立节点分别划分为一个升级 组。
例如, 如图 3所示的 10个节点, 可以首先将节点 1与节点 1的邻接 节点之间的链接屏蔽掉, 即节点 1与节点 2〜节点 9之间的链接, 屏蔽掉 链接后的结果如图 4所示, 选出在将节点 1与节点 1 的邻接节点之间的 链接屏蔽掉后链接个数最多的节点, 有节点 4、 节点 2、 节点 5、 节点 6 , 将节点 4及节点 4的邻接节点分为一个组, 即将节点 4、 节点 3、 节点 5、 节点 6分为一个组, 标记为 A组, 而后屏蔽 A组内所有的节点, 删除后 的结果图 5所示, 而后将剩余的节点中链接最多的节点, 即节点 8和节 点 9分为一个组, 标记为 B组, 令剩余的孤立节点 2、 节点 7各自构成 一个组, 并标记为 C组、 D组, 由于节点 10不直接与节点 1相连, 因此, 此处不存在节点 10的分组。
或者, 还可以采用其他的算法进行分组, 例如还可以采用数据挖掘 算法, 例如 K-means算法这种典型的基于距离的聚类算法, 具体采用何 种算法可以根据实际需求来设置, 本实施例不做限定。
S205、 首节点向每个升级组中的第一节点发送第二升级指令及本升 级组的优先升级队列。 具体的, 在完成分组后, 首节点可以根据每个升级组的优先级顺序
依次向所述每个升级组中的第一节点发送所述第二升级指令及本升级组 的优先升级队列。 这里的优先级可以是按照生成分组的时间先后自动决 定的, 即首先生成的分组具有最高的优先级, 最后生成的分组具有最低 的优先级, 当然也可以采用其他的方法确定各组的优先级, 例如, 通过 升级组中节点的数量来确定, 数量多的升级组优先级高, 以加快升级的 速度, 本发明对此并不限制。
5206 , 每个升级组的第一节点根据第二升级指令及本升级组的优先 升级队列对本升级组中的节点进行升级。 各升级组的第一节点接收到第一节点发送的第二升级指令后, 判断 自身是否需要升级, 若需要升级, 则第一节点根据所述第二升级指令从 所述首节点下载所述升级包进行升级, 并保存所述升级包; 第一节点根据第二升级指令, 按照所接收的本升级组的优先升级队 列依次向本升级组中的其他节点发送第三升级指令, 以便其他节点根据 接收的升级指令进行升级。
5207、 除首节点外的每个节点在自身已升级后, 对自身的邻接节点 进行扫描, 并将自身的邻接节点中需要升级的节点进行升级。 具体的, 除首节点外的每个节点根据所接收的后续升级指令进行升 级, 这里的后续升级指令是指包括首节点发送给各升级组中的第一节点 的第二升级指令、 各第一节点发送给本升级组内的其他节点的第三升级 指令、 各节点发送给所搜索到的自身的邻接节点中需要升级的其他节点 的第四升级指令中的任一种升级指令; 除首节点外的每个节点在自身已 升级后, 对自身的邻接节点进行扫描, 得到自身的邻接节点的升级情况, 根据自身的邻接节点的升级情况向其中需要升级的节点发送第四升级指 令以便需要升级的节点根据第四升级指令进行升级。
当然, 除首节点外的每个节点在接收到后续升级指令后, 也可以先 判断自身是否需要升级, 当自身需要升级时, 从发送后续升级指令给自 己的上一个节点获取升级包, 并根据自身的负载判断是否满足升级条件。 当满足升级条件时, 根据后续升级指令进行升级, 并保存升级包; 当不 满足升级条件时, 再次判断是否满足升级条件, 直至满足升级条件后, 根据接收的后续升级指令进行升级, 且保存获取的升级包。
例如, 优先级最高的组内的第一节点为当前需要升级的节点, 简称 当前节点。 该当前节点在接收到上一级节点, 也就是首节点发送的升级 指令和本组节点的升级队列后, 该当前节点判断自身是否已升级。 当前 节点已升级时, 当前节点就扫描自身的邻接节点, 得到自身的邻接节点 的升级情况, 而后, 当前节点按照节点的优先升级队列向自身的邻接点 发送第三升级指令, 令当前节点的邻接点根据节点的优先升级队列和升 级包进行升级; 若当前节点需要升级时, 当前节点从上一节点, 即首节 点获取升级包。 而后, 当前节点根据自身的负载判断是否满足升级条件; 若满足升级条件, 则当前节点根据升级包进行升级, 并保存升级包; 若 当前节点不满足升级条件, 则当前节点再次判断是否满足升级条件, 直 至当前节点满足升级条件且根据升级包进行升级, 并保存升级包。 在完 成升级后, 当前节点需要上报其上一节点, 这里指首节点。 当当前节点完成升级后, 向节点的升级队列中规定的下一个节点发 送第三升级指令, 以便该下一个节点进行升级, 同时当前节点还要对自 身的邻接节点进行扫描, 查找自身的邻接节点中需要升级的节点, 并向 自身的邻接节点中需要升级的节点发送第四升级指令, 使这些需要升级 的节点进行升级。
接收到第三升级指令或第四升级指令的各节点, 在完成自身的升级 后, 对自身的邻接节点进行扫描, 查找自身的邻接节点中需要升级的节 点, 并向自身的邻接节点中需要升级的节点发送第四升级指令, 使这些 需要升级的节点进行升级。 当上述优先级最高的组内的所有节点升级完成后, 首节点向优先级 第二高的组的第一个节点发送第二升级指令和节点的优先升级队列, 使 该组内的节, 按照节点的优先升级队列进行升级, 具体方法与上述优先 级最高的组内的节点的升级方法完全相同, 不再贅述。
示例性的, 假设网络中有 1〜10共 10个节点, 其中节点 1为首节点, 节点 2〜节点 9为节点 1的邻接节点, 与节点 1直接相连, 而节点 10为节 点 5的邻接节点。
若分组时采用的是 S204中的第一种分组方法, 则分为 8个组, 每个 组内有一个节点, 分别为节点 2〜节点 9 , 节点 10不分组。 在完成分组后,
节点 1先向第一组发送升级指令, 即先升级节点 2 , 节点 2在完成升级后 上报给节点 1 , 节点 1向第二组发送升级指令, 即升级节点 3 , 同时节点 2扫描到其邻接节点 6需要升级, 所以节点 2向节点 6发送升级指令, 令 节点 6也升级, 这样就实现了节点 3与节点 6同时升级, 节点 3在完成 升级后上报给节点 1 , 而由于节点 6的升级并不是由节点 1下发的任务, 因此, 节点 6升级完后并不向节点 1上报, 而是向节点 2上报, 当然可 以再由节点 2向上级节点节点 1上报。 而后节点 1 向第三组发送升级指 令, 即升级节点 4 , 同时节点 6在完成升级后扫描到其邻接节点 7需要升 级, 所以节点 6向节点 7发送升级指令, 令节点 7也升级, 这样就实现 了节点 4与节点 7同时升级, 节点 4在完成升级后上报给节点 1 , 而由于 节点 7的升级并不是由节点 1 下发的任务, 因此, 节点 7升级完后并不 向节点 1上报, 而是向节点 6上报, 也可以由节点 6再向上级节点节点 2 上报。 而后节点 1向第四组发送升级指令, 即升级节点 5 , 节点 5在完成 升级后上报给节点 1 , 而此时节点 1发现第五组的节点 6和第六组的节 点 7 已完成升级, 此时, 可以是节点接收各节点逐级上报的结果得到的 相关升级情况信息, 当然, 也可以采用节点 1 自己扫描相邻节点的方法 获取相关升级情况信息, 或者是节点 1 向第五组的节点 6和第六组的节 点 7发送升级命令时发现节点 6、 7已完成了升级,本发明对此并不限制。 故节点 1向第七组发送升级指令, 即升级节点 8 , 同时节点 5在扫描到其 邻接节点 10需要升级后, 向节点 10发送升级指令, 令节点 10升级, 这 样就实现了节点 8与节点 10同时升级, 节点 8在完成升级后上报给节点 1 , 而由于节点 10的升级并不是由节点 1下发的任务, 因此, 节点 10升 级完后并不向节点 1 上报。 最后, 节点 1 向第八组发送升级指令, 令节 点 9升级。 这样就完成了所有节点的升级, 可以看出, 节点 3和节点 6、 节点 4和节点 7、 节点 8和节点 10是同时升级的, 节省了升级时间。
若分组时采用的是 S204中的第二种分组方法, 则分为 5个组, A组 包括: 节点 4、 节点 3、 节点 5和节点 6 , B组包括节点 8、 节点 9 , C包 括节点 2 , D组包括节点 7 , E组包括节点 10。
在完成分组后, 节点 1先向 A组的节点 4发送升级指令, 令节点 4 升级, 节点 4完成升级后上报节点 1 , 而后节点 4按照 A组的优先升级 队列向下一个节点, 即节点 3发送升级指令, 令节点 3升级, 同时节点 4
在扫描到其邻接节点 5 需要升级后, 向节点 5发送升级指令, 令节点 5 升级, 这样就实现了节点 3和节点 5 同时升级, 在节点 3和节点 5完成 升级后上报给节点 4以便节点 4上报给节点 1。 而后节点 4按照节点的优 先升级列表向节点 6发送升级指令, 令节点 6升级, 同时节点 5扫描到 其邻接节点 10需要升级后, 向节点 10发送升级指令, 令节点 10升级, 这样就实现了节点 6和节点 10同时升级, 节点 6在完成升级后上报给节 点 4以便节点 4上报给节点 1 , 而由于节点 10的升级并不是由节点 1下 发的任务, 因此, 节点 10升级完后并不向节点 4上报。 此时, 就完成了 A组的升级, 故节点 1向 B组的节点 8发送升级指令, 令节点 8升级, 同时节点 6在扫描到其邻接节点 2和邻接节点 7需要升级, 因此, 在节 点 8升级时, 节点 6向节点 2发送指令, 这样实现了节点 8和节点 2的 同时升级, 由于节点 2并不是节点 1下发的任务, 所以节点 6不向节点 4 上报。 节点 6向邻接节点 7发送升级指令, 同时节点 8根据 B组的优先 升级队列向下一个节点 9发送升级指令, 实现了节点 7与节点 9 的同时 升级, 由于节点 9的升级是节点 1给节点 8下发的任务, 节点 8 向节点 1上报节点 9 的升级情况。 节点 1依次向 C组节点 2和 D节点 Ί以及 E 组节点 10 下发升级指令时发现三个节点均已完成升级,从而本轮升级结 束。
这样就完成了所有节点的升级, 可以看出, 节点 3和节点 5、 节点 6 和节点 10、 节点 7和节点 9是同时升级的, 节省了升级时间。
S208、 首节点检查所有节点的升级情况, 判断是否有升级失败的节 点, 如果有升级失败的节点, 则重新执行 S204〜S207 , 直至所有节点完 成升级; 如果没有升级失败的节点则升级结束。
由于在除首节点外的每个节点完成升级后, 都会向首节点上报升级 情况, 首节点根据上报的升级情况判断是否有升级失败的节点。 例如, 可以通过以下方式实现: 每个节点完成升级后扫描自身的邻 接节点并生成邻接表 (该邻接表用于存储邻接节点的升级情况) , 每个 节点在生成邻接表后发送给首节点, 当所有节点执行过一次升级后, 首 节点也就得到了所有节点上报的邻接表, 而后首节点根据这些邻接表就 可以检查所有节点的升级情况, 从而判断出是否存在升级失败的节点。
本发明的实施例提供一种升级的方法, 在需要升级的节点网络中, 首节点在接收到升级指令后, 将扫描到的节点分组, 并向各分组的第一 个节点下达优先升级列表, 各分组的第一个节点根据优先升级列表将组 内节点升级, 分组内的节点在自身升级后要扫描与其相连的节点升级情 况并对需要升级节点进行升级, 被升级节点只需要和初始升级节点存在 通路就可以完成升级, 从而提高了升级的成功率, 而且实现了多个节点 并行升级, 提高了升级效率。
