In step 331, receives cluster interior nodes response to network address and obtain request and the response bag of return.
Wherein, as previously described, each node in cluster, receive network address obtain request after all will to this into
Row response, to newly-increased node returning response packet.Response bag is the response that node obtains network address request.
Response bag carries the network address of cluster interior nodes.Node is increased newly after initiating network address and obtaining request,
The response bag that cluster internal point or all nodes return will be received, any response bag has the network address of respective nodes,
So far, newly-increased node is just enable to obtain the network address that can realize interaction in cluster.
In step 333, the extraction of network address in response bag is carried out, obtains the network address of cluster interior nodes.
Wherein, it increases the extraction that node carries out one or more response bags of reception network address respectively newly, obtains cluster
The network address of interior multiple nodes, any network address can make newly-increased node be interacted with the node in cluster.
In one exemplary embodiment, before step 330, the method which sets up is further comprising the steps of.
Judge that whether within a specified time response to network address obtains request to cluster interior nodes, if NO, then increases section newly
Point creates cluster, and as the control node of cluster, if YES, then executes this step 330.
Wherein, it increases node newly to ask once initiating network address and obtaining, just triggering timing, is within a specified time to confirm
It is no obtain cluster interior nodes response then illustrate that cluster is not created if NO, newly-increased node can as control node and
Cluster is created, and then waits for other newly-increased nodes that cluster is added.
Control node is used to control the realization of various functions in the adition process and cluster that increase node in cluster newly.It is right
In a cluster, there is a control nodes.Each node all stores cluster interior nodes information, cluster interior nodes information in cluster
At least have recorded the node of cluster internal administration and the network address of each node.As a result, any node all has in cluster
The standby condition for becoming control node, once and then control node break down, can be the new control node of cluster configuration, a side
Face ensure that the disaster tolerance in cluster, on the other hand also ensure the robustness of cluster.
If newly-increased node has within a specified time obtained the response of cluster interior nodes, thus respond with obtaining network
Location, i.e., as shown in step 331 to step 333.
Further, the signified response for whether within a specified time obtaining cluster interior nodes, as whether when specified
The interior response bag for obtaining cluster interior nodes.It initiates after network address acquisition is asked if timing has reached specified time,
But it is not responded yet, that is, receives response bag, then illustrate that cluster is not populated, newly-increased node directly carries out the wound of cluster
It builds.
In step 350, cluster is added by network address request.
Wherein, after obtaining network address by the response of cluster interior nodes, you can via the network address request of acquisition
Cluster is added.As previously described, the network address that cluster interior nodes are responded and obtained may be one or more, in acquisition
When network address is multiple, a network address will be chosen and ask that cluster is added.
In step 370, it is performed and newly-increased node is made to obtain cluster internal segment with increasing node in cluster newly operation is added
Point information completes the cluster adition process for increasing node newly.
Wherein, all will be that newly-increased node be held after any node receives the addition cluster request of newly-increased node in cluster
The corresponding cluster adition process of row.Can be collection herein it should be noted that receiving the node that cluster request is added in cluster
The control node of group, can also ordinary node in cluster.
It is control node to receive and the node of cluster request is added, then can directly execute and increase node addition behaviour in cluster newly
Make；It is ordinary node in cluster to receive and the node of cluster request is added, then cluster request will be added by, which needing, is forwarded in cluster
Control node.
It increases nodal operation in cluster newly, refers to the operation executed for the addition of newly-increased node in cluster.Show at one
In example property embodiment, according to the difference that cluster request is added is received, it is different to increase nodal operation newly in performed cluster.
It increases and will add specifically, increasing nodal operation newly relative to control node, in the cluster performed by ordinary node in cluster
Enter the process that cluster request is forwarded to control node.
In addition to this, no matter which kind of node, in cluster increase newly node be added operation will all execute to newly-increased node return
Response bag, and all nodes carry out the notice of newly-increased nodal information into cluster, in this regard, the cluster for just completing to increase newly node adds
Enter process.
By exemplary embodiment as described above, the Dynamical Deployment of cluster interior nodes is realized so that any newly-increased section
Point can flexibly rapidly join cluster, reduce the complexity of cluster establishment, increase the flexibility of cluster management, Ren Yixin
Increasing node can be automatically added in cluster.
Fig. 6 is the flow chart that the details to step 350 according to fig. 3 shown in corresponding embodiment is described.The step
350, as shown in fig. 6, may comprise steps of.
In step 351, the network address of cluster interior nodes is randomly selected.
Wherein, as previously described, the network address that multiple nodes in cluster are obtained by the response of cluster interior nodes, at this
In a little network address, randomly selecting for a network address is carried out, the network address for randomly selecting and obtaining is real for increasing node newly
Now with the communication of cluster interior nodes.
In step 353, itself connection between cluster interior nodes is created according to the network address randomly selected.
In step 355, initiate that cluster request is added by the connection of establishment.
By exemplary embodiment as described above, newly-increased node is able to establish with a node in cluster and connect, and the section
Point can be interconnected as the node in cluster with other meshed networks in cluster, therefore increasing node newly can be via connecting
The node that connects and the adition process for initiating to increase newly node rapidly in cluster, having very high cluster is added flexibility, does not need
Any operation bidirectional.
Further, Fig. 7 is the flow chart being described according to the details to step 351 shown in Fig. 6 corresponding embodiments.
In one exemplary embodiment, step 351, as shown in fig. 7, may comprise steps of.
In step 3511, the network address of static configuration is obtained, network address corresponds to all nodes of cluster internal administration
In other nodes of same multicast group are not in newly-increased node.
Wherein, the network address of static configuration refers to the network address of one or more node cluster Nei.It will be in cluster
The network address of one or more node is fixedly configured in newly-increased node, initiates to carry out follow-up for newly-increased node
Node connection and be added cluster request initiation.
The network address for carrying out static configuration in newly-increased node, also corresponds to the node in cluster, still, corresponding
Node and newly-increased node and untreated same multicast group.
In step 3513, the network that the by of asking obtains is obtained in the network address of static configuration and by network address
In location, a network address is randomly selected.
Wherein, it increases newly in node, on the one hand by the static configuration of progress, there is some network address, on the other hand,
Obtaining request by the network address that multicast is initiated, there is also some other network address.This two classes network address, can
So that newly-increased node is communicated with the node in cluster.
Therefore, newly-increased node will randomly select a network address in this two classes network address.That is, showing at one
In example property embodiment, the network address carried out randomly selects the network address for being no longer confined to obtain by multicast, even if collection
There is no the nodes that same multicast group is in newly-increased node can also realize being automatically added to for cluster in group, eliminates limitation
Property, reduce due to being constrained caused by multicast, realizes that cluster is set up under multicast and static network address immixture.
In another exemplary embodiment, for the network address of static configuration and by network address obtains request
The network address of acquisition, newly-increased node will use a network address to establish connection, and then create cluster, if a connection failure,
Another network address is then used, and so on, if all connection all fails, increase the establishment that node carries out cluster newly, itself will
Control node as created cluster.
Which kind of by this exemplary embodiment, for the establishment of cluster and addition, no matter equal in situation ensure that
It can realize that cluster, the stability that cluster is set up are enhanced.
Corresponding, as the generation of colonization process is added in newly-increased node, cluster interior nodes will also ring this
It answers, i.e., with respect to a kind of method realized cluster and set up is realized, is applied in the node disposed in cluster.
Fig. 8 is a kind of flow chart of method for realizing cluster establishment shown according to an exemplary embodiment.The realization collection
The method that group builds, as shown in figure 8, may comprise steps of.
In step 510, node receives the network address acquisition request of multicast, and multicast network address obtains the node of request
It is the newly-increased node of cluster.
Wherein, cluster internal administration has node, a node of cluster internal administration to be in multicast group, and newly-increased node is also at the group
Broadcast group.The node for being in same multicast group in cluster with newly-increased node all asks acquisition network address acquisition.
In step 530, response to network address obtains request and returns to itself network address.
Wherein, the network address request response that cluster interior nodes are carried out, is to carry own net address by return
Response bag is realized.Specifically, cluster interior nodes are after it receives network address acquisition request, response to network address obtains and asks
The acquisition for carrying out own net address is asked, and is packaged, the response bag for carrying own net address is returned to newly-increased node.
In step 550, as cluster is added according to network address request in newly-increased node, executes and increase node addition behaviour newly
Make.
Wherein, the inevitable one node initiation addition cluster request into cluster with the acquisition of network address of node is increased newly,
So that cluster interior nodes are triggered to execute newly-increased node addition operation.Specifically, operation is added by collecting in newly-increased node
Control node executes in group, receives the node node in order to control that cluster request is added；It certainly, also can be by cluster one common section
Point and control node execute jointly, in the case where it is ordinary node to receive the node that cluster request is added.
It is appreciated that the realization of cluster is added for increasing node newly, any node for receiving its request, all may be used in cluster
Operation is added to initiate to increase newly node, need not be initiated by specific node, so that cluster interior nodes ask newly-increased node
It asks addition that any constraint is not present, while flexibility is high, ensures the dynamic change of cluster interior nodes.
Fig. 9 is the flow chart being described according to the details to step 550 shown in Fig. 8 corresponding embodiments.The step
550, as shown in figure 9, may comprise steps of.
In step 551, node is linked by increasing the connection that node carries out newly and creating with newly-increased node, increases section newly
Connection in point, which creates, to be executed according to the network address randomly selected..
Wherein, as previously described, increase node newly after the network address of several nodes, will carry out net in acquisition cluster
Network address randomly selects, and therefrom obtains a network address.By this network address of acquisition, in cluster respective nodes with it is new
Increase node and realizes connection between the two.
In step 553, newly-increased node is carried out by connection and initiates the reception that cluster request is added.
In step 555, receive be added cluster request node judge itself whether be cluster control node, if it is
It is to then follow the steps 557, if NO, thens follow the steps 559.
Wherein, the node that cluster request is added is received, is needed to newly-increased node response.Specifically, will first determine whether
Whether itself is existing as the control node of cluster, if it is, directly respectively to owning in newly-increased node and cluster
Node executes corresponding information and issues, and is asked to control node if it is not, then cluster is added in forwarding, by control node come to new
Photos and sending messages under all nodes in increasing node and cluster.
In step 557, into newly-increased node and cluster, all nodes, which execute, increases node addition operation newly, makes newly-increased node
Cluster interior nodes information is obtained, all nodes obtain newly-increased nodal information in cluster, complete the cluster adition process for increasing node newly.
Wherein, for increasing node newly, the addition cluster initiated it request is needed to return to respective response packet, to increase newly
Node can obtain cluster interior nodes information, and cluster is added；
For cluster interior nodes, as previously described, each node is all stored with the cluster interior nodes corresponding to all nodes
Information, when the node of cluster internal administration changes, i.e., the addition of newly-increased node, therefore should be by newly-increased nodal information into cluster
Each node issues, and then ensures that each node stored information is adapted with the node deployment of cluster, ensure that information storage
The promptness of integrality and dynamic change.
In step 559, cluster will be added and ask the control node for being forwarded to cluster.
By exemplary embodiment as described above, under the action of control node, certainly, in the case that a certain, also deposit
In the cooperation of an ordinary node, the realization of cluster no longer needs to rely on control node this single-point, any to receive addition
The node of cluster request, all executes cluster adition process for that can increase node newly.
In another exemplary embodiment, after step 550, the method which sets up further includes following step
Suddenly.
In cluster after control nodes break down, all nodes, which are triggered, in cluster carries out the selection of new control node.
Wherein, as previously described, cluster memory is in a control node, but all nodes all store in cluster in cluster
Nodal information, the topological structure of cluster interior nodes message reflection cluster internal administration node, therefore, control node once occur therefore
Barrier, the new control node between making triggering carry out all nodes are chosen, and make for example, choosing the longest node of existence time in cluster
For new control node, or the selection of new control node is realized using some other given algorithm, herein without limiting.
As a result, just so that control node has disaster tolerance performance in cluster, no longer there is cluster in the generation of control node failure
The case where can not operate normally ensure that the reliability and robustness of cluster.
In conjunction with concrete application scene, description increases respective nodes in the method that the realization cluster is set up in node and cluster newly
Realization.As previously described, the method which sets up can be applied to the server cluster portion under any network application
Administration.
