Abstract
The invention discloses a load sharing method of multiple module Short Message System, including a number of nodes for the short message treatment and the contents as described below : based on the actual configuration of each node to distribute each node processing capacity ratio value; selecting eigenvalue from SMS; ratio values of each node are summarized to get a base value; making the eigenvalue of the short message conduct modulus operation to get modulus; according to the modulus and integrating the ratio values of each node to know that the short message should be processed by which node. The invention can well distribute message of multiple module short message system, in which messages can be well distributed whether the node is under normal condition or abnormal condition. The method is simple and practical.
Description
Technical field
The present invention relates to a kind of telecommunications SMS method, in particular a kind of load share method of multi module short message system.
Background technology
Along with the continuous development of short message service, require also in continuous raising for the disposal ability of note system.As the Short Message Service Gateway in the note system, owing to be the hinge that connects each equipment, the requirement of disposal ability that therefore improves Short Message Service Gateway is just more obvious.
The ability of present Short Message Service Gateway generally can reach 1000/second disposal ability, supports 3000 and 5000/second gateway but there has been operator to propose to build at present.For such disposal ability, the single node gateway can not meet the demands, and therefore needs gateway distributed, multinode to satisfy.
For gateway distributed, multinode, wherein have a core problem be exactly how effectively with load sharing on each processing module, thereby allow each module can give full play to the disposal ability of oneself, finish the processing of magnanimity short message.Because the difference of the hardware of each processing module, the disposal ability of each processing module there are differences, so load sharing just should come distribution load according to the disposal ability of disparate modules, but also will consider after wherein some processing modules go wrong, how the load of this processing module disposal ability according to remaining module is assigned on the remaining processing module.
Also open in the prior art without any technology about the multimode load share method.
Summary of the invention
Purpose of the present invention just provides a kind of load share method of multi module short message system, and this method can be come distribution load by the practical capacity of each processing module; When one of them processing module goes wrong, the load of this module can be assigned to remaining module according to the disposal ability of being left module.
The technical scheme of the inventive method comprises:
A kind of load share method of multi module short message system, it comprises that a plurality of nodes are used for the processing to short message, described method comprises the steps:
A, distribute the ratio value of each node processing ability by the actual disposition of each node;
B, from content of short message, select characteristic value;
C, the ratio value addition of each node is obtained the radix value;
D, the characteristic value of this short message is carried out modulo operation by described radix value obtain modulus;
E, according to the ratio value of gained modulus in conjunction with each node, obtaining this short message should by which node processing.
Described method, wherein, described method also comprises:
F, when the node processing capability state changes, the node ratio value addition of each normal condition is obtained new radix value, and carries out load sharing according to this.
Described method, wherein, described characteristic value has randomness.
Described method, wherein, described characteristic value is the source Mobile Station International ISDN Number of pending short message.
Described method, wherein, described characteristic value is the message SN of pending short message.
The load share method of a kind of multi module short message system provided by the present invention; good treatment in the short-message system of multimode the problem of message distribution; and no matter make message distribution be that node state is normal or message occurs can both well pro rata distributing when unusual, and the inventive method is simple, practical.
Description of drawings
Fig. 1 is the treatment step figure of the inventive method;
Fig. 2 is the distribution of messages flow chart in the inventive method.
Embodiment
Below in conjunction with accompanying drawing, will the preferred embodiment of the inventive method be described below:
The load share method of multi module short message system of the present invention, as shown in Figure 1, it comprises that mainly each step is as follows:
1, the ratio value that distributes each node processing ability by the actual disposition of each node.
2, select characteristic value from content of short message, the selection principle of characteristic value is to have randomness.
3, the ratio value addition with each node obtains the radix value.
4, the characteristic value of short message is carried out modulo operation by radix and obtain modulus.
5, according to the ratio value of modulus in conjunction with each node, should thereby obtain this short message by which node processing.
6, change as node state, the ratio value addition with the normal condition node obtains new radix so, repeats for the 4th, 5 steps then.
According to the flow process of Fig. 1 the implementation process of the inventive method is described below by an object lesson, supposes that this short-message system is made up of 3 processing nodes, as shown in Figure 2:
1. distribute the ratio of disposal ability separately according to 3 nodes hardware configuration separately, node 1 is 20%, and node 2 is 30%, and node 3 is 50%, and this ratio also can be expressed with 2: 3: 5.
2. according to the characteristics of short message, can choose source Mobile Station International ISDN Number in the short message back 4 as characteristic value because source Mobile Station International ISDN Number itself has randomness, back 4 of number also have randomness.Also can choose the message SN of short message in addition, because message SN also has randomness.With behind the source Mobile Station International ISDN Number 4 be example, the original number of supposing a piece of news is 01064397539, then back 4 is 7359, the characteristic value of this message is 7359 so.
3. with the ratio value addition, first kind of ratio adds up to 20+30+50=100, and then radix is that 100, the second kinds of ratios add up to 2+3+5=10, and then radix is 10.
4. characteristic value 7359 is pressed radix 100 deliverys, then modulus is 59; Press radix 10 deliverys, then modulus is 9.
5. according to flow process shown in Figure 2, the modulus scope of the short message that described each node can handle is set, ratio value as node A, B, C is respectively M1, M2, M3, described node A then can be set handle the short message that modulus value M meets 0≤M＜M1 requirement, Node B is handled the short message that modulus value M meets M1≤M＜(M1+M2), and node C handles the short message that modulus value M meets (M1+M2)≤M＜(M1+M2+M3).Therefore, if modulus is 59, then modulus is greater than 50, and this message is handled by node 3; If modulus is 3, then modulus is greater than 5, and this message is handled by node 3.
6. if wherein node 2 goes wrong, as long as recomputate radix so, as first kind of situation radix is 20+50=70, and second kind of situation radix is 2+5=7, then to 7539 deliverys, then be respectively 49 and 0 according to new modulus, according to the flow process of Fig. 2, under new modulus situation, if the former modulus is 49 o'clock, then this message is handled by node 3, and 0 this message of modulus is handled by node 1.
So, just can realize load sharing to the short-message system of a plurality of modules, and the simple and clear practicality of its sharing method, when certain a few module breaks down, and can carry out load sharing automatically again.
But should be understood that; above-mentioned description at specific embodiment is comparatively detailed; can not therefore think restriction to scope of patent protection of the present invention; scope of patent protection of the present invention should be as the criterion with claims; the institute that those skilled in the art are done under the situation that does not break away from above-mentioned technical conceive changes or replaces, and all should belong within the scope that patent of the present invention asks for protection.
