Below in conjunction with Figure of description the embodiment of the invention is described in detail, various embodiments of the present invention can be applied in the P2P VoIP system, and the terminal that relates to can be a P2P VoIP terminal, and the business that is provided by the P2PVoIP system can be provided; The node that relates to can be the core node in the P2P VoIP system, authentication information and the user contracting data of storage terminal in the P2P VoIP system, and the registration and the authentication of execution terminal can also be carried out voip conversation controlled function and supplementary service logic.
Embodiment one:
As shown in Figure 1, for carrying out the method schematic diagram that load heavily distributes in the embodiment of the invention one, said method comprising the steps of:
Step 101: first node detects the load of self, judges whether to take place sudden load.
Step 102: when the load of first node detection self reaches first setting threshold and do not reach second setting threshold, at least one terminal that is connected to self is redirected to Section Point.
The load of Section Point is less than threshold value.The load of Section Point represents less than threshold value that Section Point is current and is in relatively idle state, for example: the size of threshold value can be set to node maximum load 50%.
The load of first node reaches first setting threshold and is meant that sudden load has taken place first node, at this moment, first node need be redirected to Section Point with the fractional load of self, that is to say, first node will be redirected to Section Point at least one terminal of self registering, to alleviate the load of first node.
The size of first setting threshold can rule of thumb be worth setting, equal as the size of first setting threshold node maximum load 80%; Second setting threshold is greater than first setting threshold, and the load of expression node reaches higher degree, equal as the size of second setting threshold node maximum load 90%.
Step 103: the first node indication is redirected to the terminal of Section Point and heavily registers to Section Point.
At this moment, originally the terminal in the first node registration is redirected to Section Point, is responsible for being redirected the registration and the session control of back terminal by Section Point, just with the load transfer of first node to Section Point.
By the scheme of step 101～step 103, the node that sudden load takes place initiatively carries out redirect operation to other idle relatively nodes, has avoided operating by host node the drawback of the delay that brings.Because first node can not carry out load by host node and heavily distributes in the present embodiment, therefore, first node can determine in the system that load is less than the Section Point of threshold value by following dual mode at least:
First kind of mode:
The idle node information that the host node of first node reception self returns, and from the idle node of described idle node information correspondence, select a node as Section Point.Under the manner,, when sudden load takes place first node, can return available idle node information to first node according to the request of first node by the load condition of each node in the host node detection system.
The second way:
First node is determined the node of load less than threshold value by subscribing to other node load information, and selects a node as Section Point from the node of determining.Under the manner, each node is known by the load information of subscribing to other nodes and is in relatively idle node in the system in the system.
Further, load continuation increase when first node, first node can be by adjusting the load that the network topology node reduces self, be first node with the part address space transfer of self service to other idle relatively nodes, heavily distribute by such load to make the whole network reach load balancing.
First node is adjusted the network topology node, and to reduce self the step of load as follows:
Step 104: when first node reaches second setting threshold in the load that detects self, with space transfer to the three nodes of location at least in part of self serving.
The load of described the 3rd node is less than threshold value.If the load of the Section Point in the step 102 after the heavily registration of receiving terminal is during still less than threshold value, then Section Point in this step and the 3rd node can be same node point, can certainly be different nodes.
In the scheme of present embodiment one, step 104 can be carried out after step 103, reaches second setting threshold if first node is determined the load of self when step 101 is carried out load detecting, then can be in the content of direct execution in step 104.
In step 104, first node can utilize the dummy node technology, and the address space of self serving is transferred to the 3rd node, and different with the relation of the 3rd node according to first node, concrete operation is as follows:
First kind of situation:
If first node and the 3rd node are adjacent nodes, then the first node basis is transferred to the definite node ID value that will be updated in space, the 3rd address of node, and upgrades the node ID value of node ID value for determining of self.
For example, the node ID of first node is 5, is responsible for being designated 5 IP address fields of 1～5, and the IP address belongs to the endpoint registration of these 5 IP address fields to first node; The 3rd node and first node are adjacent nodes, and the node ID of the 3rd node is 8, are responsible for being designated 3 IP address fields of 6～8, and the IP address belongs to endpoint registration to the three nodes of these 3 IP address fields.Because the load of current first node is excessive, therefore, first node needs to be designated 2 IP address spaces of 4,5 and is transferred to the 3rd node, the node ID value of then determining to be designated 2 IP address space correspondences of 4,5 is 4,5, then the node ID value with self is reduced to 3 by 5, the expression first node only is responsible for being designated 3 IP address fields of 1～3, is designated 2 IP address fields of 4,5 and is responsible for by the 3rd adjacent node.
Second kind of situation:
If first node and the 3rd node are not adjacent nodes, then first node is according to being transferred to the definite node ID value that will be updated in space, the 3rd address of node, upgrade the node ID value of node ID value of self for determining, and the ID value of other node updates self between indication and the 3rd node, node ID value after the size of the node ID value after wherein, first node upgrades and other node updates big or small identical.
For example, the node ID of first node is 5, is responsible for being designated 5 IP address fields of 1～5, and the IP address belongs to the endpoint registration of these 5 IP address fields to first node; The 4th node and first node are adjacent, and the node ID of the 4th node is 10, are responsible for being designated 5 IP address fields of 6～10, and the IP address belongs to endpoint registration to the four nodes of these 5 IP address fields; The 3rd node is adjacent with the 4th node, and the node ID of the 3rd node is 15, is responsible for being designated 5 IP address fields of 11～15, and the IP address belongs to endpoint registration to the three nodes of these 5 IP address fields.
Step 105: the terminal of first node indication IP address in the address space that shifts heavily registered to the 3rd node.
