The workflow of the router is as follows:

1) startup program；

2) initial work is carried out；

3) data are received；

4) code compilation and DECLARE partial code is executed；

5) BEGIN-END partial code is executed；

6) destination node is sent data to.

A kind of design method of the router of configurable server engine of the invention compared to the prior art, can To pass through the routing of data between the flexible customized required business processing flow of configuration file and multiple business modules；According to not Same business, it is only necessary to configuration file and dynamic base are write, it is not necessary to modify the codes of engine, and the work that exploitation customizes can be completed, The workload of secondary development is greatly saved, the trend of future server engine technique development will be become.

Detailed description of the invention

Attached drawing 1 is a kind of work flow diagram of the router of configurable server engine.

Specific embodiment

Embodiment 1:

The router includes service management module, routing management module and node communication module；

Service management module: each business section in multiple service nodes is arranged by XML configuration file for abbreviation BM module The configuration information of point initializes node by loading the above configuration file, creates a process for each node；Each business Node has the configuration file of the corresponding .def of a nodename, and the specific industry of the node is arranged by .def configuration file Business；It can be simple pretreatment, can be completed by configuration file；It is also possible to complicated service logic, it is dynamic by writing It realizes in state library.

For example, general process flow is different to execute according to the actuating code (act_cod) received in message The content of dynamic base, specific node1.def is as follows:

DECLARE

BEGIN

STEP001:

SET #sys1="00001"

GOTO STEP003

STEP002:

CHECK #act_code

GOTO STEP003 IF 8501

GOTO STEP004 IF 8502

STEP003:

DO update_1000

GOTO STEP005

STEP004:

DO waf_update_2000

GOTO STEP005

STEP005

END

Wherein: DECLARE keyword is preparation；

BEGIN keyword is the beginning for identifying configuration file；

The end of END keyword identification configuration file；

The value of CHECK keyword inspection variable；

IF keyword is condition judgement；

DO keyword is the dynamic base for executing respective name；

GOTO keyword is skip instruction.

<?xml version= "1.0" encoding= "GBK" ?>

<ROUTE>

</ENTRY>

</ENTRY>

</ENTRY>

</ENTRY>

</ENTRY>

</ENTRY>

</ENTRY>

</ENTRY>

</ROUTE>
