Embodiment
The embodiment of the present invention provides a kind of method of network node upgrading, can reduce the complexity of network node upgrading.The embodiment of the present invention also provides corresponding Apparatus and system.Below be elaborated respectively.
In the embodiment of the present invention, Centroid is to have the node that function is controlled in management, and destination node is also in child node.Centroid and child node are all the equipment in network.
Consult Fig. 1, from the angle of Centroid, an embodiment of the method for the network node upgrading that the embodiment of the present invention provides comprises:
101, Centroid obtains the sign of the destination node that will upgrade.
When Centroid will be given certain the child node upgrading in network, first to obtain the sign of the destination node that will upgrade.
102, Centroid is determined the message path from Centroid to destination node according to the sign of described destination node.
103, Centroid creates the set that comprises the sign of each child node in described message path.
Determine after the message path from Centroid to destination node, list the sign of each child node in message path in a set, when the data format of modulation upgrading message, the set that comprises the message of each child node on path is modulated on data format.
104, Centroid sends upgrading message to described destination node, in described upgrading message, carry the set of the sign of destination node and the sign of described each child node, so that the part or all of child node in described each child node need to upgrade time, is upgraded according to described upgrading message.
Centroid sends after upgrading message, upgrading message can arrive each child node on path along transmission path, and child node is resolved upgrading message, when the sign of child node self is identical with the sign of destination node, illustrate that this child node is destination node, upgrades according to upgrading message.When parsing the sign of child node self and the sign of destination node is not identical, but in the sign set of child node, whether the version information that further judges self is lower than the version information of upgrading message, when self version information is the version information lower than upgrading message, according to upgrading message, upgrade, and upgrading message is transmitted to next child node.
The embodiment of the present invention adopts the sign of obtaining the destination node that will upgrade; According to the sign of described destination node, determine the message path from Centroid to destination node; The set that establishment comprises the sign of each child node in described message path; To described destination node, send upgrading message, in described upgrading message, carry the set of the sign of destination node and the sign of described each child node, so that the part or all of child node in described each child node need to upgrade time, is upgraded according to described upgrading message.Compared with prior art, the method for the node upgrading that the embodiment of the present invention provides, the child node from Centroid to destination node on the path of centre also can be upgraded according to upgrading message, has greatly reduced the complexity of network node upgrading.
Alternatively, on the basis of embodiment corresponding to above-mentioned Fig. 1, in another embodiment of the method for the network node upgrading that the embodiment of the present invention provides, the described concrete steps of determining the message path from Centroid to destination node according to the sign of described destination node, comprise: the version information of inquiry the whole network child node, and the layout of adding up the version information of the whole network child node; According to the layout of the version of described the whole network child node, determine the message path from Centroid to destination node.
The scheme providing because of the embodiment of the present invention not only can make destination node upgrading, and the child node on path, also can be upgraded during lower than the version information of upgrading message at version information.So Centroid is when determining the transmission path of upgrading message, the version information of the chooser node of can trying one's best is lower than the transmission path of the version number of upgrading message, to guarantee that the child node on transmission path can upgrade.
Consult Fig. 2, from the angle of child node, another embodiment of the method for the network node upgrading that the embodiment of the present invention provides comprises:
201, child node receives the upgrading message that also analytical center node sends, and carries the set of the sign of destination node and the sign of described each child node in described upgrading message.
202, child node parses the sign of child node self when identical with the sign of destination node, according to described upgrading message, upgrades.
203, child node parses the sign of child node self and the sign of destination node is not identical, and in the set of the sign of described each child node, and the version that described child node is determined self during lower than the version of upgrading message, is upgraded according to described upgrading message.
Centroid sends after upgrading message, upgrading message can arrive each child node on path along transmission path, and child node is resolved upgrading message, when the sign of child node self is identical with the sign of destination node, illustrate that this child node is destination node, upgrades according to upgrading message.When parsing the sign of child node self and the sign of destination node is not identical, but in the sign set of child node, whether the version information that further judges self is lower than the version information of upgrading message, when self version information is the version information lower than upgrading message, according to upgrading message, upgrade.
In the embodiment of the present invention, receive the upgrading message that also analytical center node sends, in described upgrading message, carry the set of the sign of destination node and the sign of described each child node; When child node parses the sign of child node self when identical with the sign of destination node, according to described upgrading message, upgrade; When child node parses the sign of child node self and the sign of destination node is not identical, and in the set of the sign of described each child node, and the version that described child node is determined self during lower than the version of upgrading message, is upgraded according to described upgrading message.Compared with prior art, the method for the node upgrading that the embodiment of the present invention provides, the child node from Centroid to destination node on the path of centre also can be upgraded according to upgrading message, has greatly reduced the complexity of network node upgrading.
Alternatively, on the basis of embodiment corresponding to above-mentioned Fig. 2, in another embodiment of the method for the network node upgrading that the embodiment of the present invention provides, described group node determination also comprises after going out the step that the sign of child node self is not identical with the sign of destination node: to next sub-node, send described upgrading message.
Group node determination go out the sign of child node self not identical with the sign of destination node after, illustrate that upgrading message is not also sent to destination node, continue upgrading message to transmit downwards, to determine that destination node finally receives upgrading message, completes upgrading.
