- 10. a kind of network service method based on multi-service Parallel Service framework described in claim 1, it is characterised in that including such as Lower step：(1) its corresponding satellite is determined by port mapping module from the business data packet of satellite network equipment physical port input Network device internal logic port, then internal frame head is added for business data packet by port mapping module, included in internal frame head The input physical port number of the data packet and corresponding internal logic port number information；(2) arbitration modules are inputted and carries out validity and filtering rule inspection, directly abandoned not if if checking；If inspection passes through Then enter step (3)；(3) VDP mapping blocks determine that business data packet needs the correspondence VDP processing units being mapped to according to VDP mapping rulers, if Map and successfully then update the VDP processing units number in internal frame head and business data packet is sent to corresponding VDP processing units； Direct discarding traffic data packet updates relevant state and statistical information at the same time if failure is mapped；；(4) domain extracting rule, matched rule and matching behavior, business of the VDP processing units to entrance are included per level-one flow table Data packet according to domain extracting rule extract data, matched according to matched rule, if successful match according to matching behavior into Row processing, the direct discarding traffic data packet if it fails to match；Update relevant state and statistical information；(5) output scheduling module carries out the treated business datum report that different VDP processing units export unified be lined up simultaneously Exported according to priority scheduling；The business data packet of output submits end user or is forwarded to other satellite network equipment.
