Embodiment Construction

[0018] The main idea of ​​the present invention is: run an operating system on the central processing unit (CPU) module of each physical node, run a plurality of process instances with the same function simultaneously on the same business application under the operating system, and a plurality of process instances concurrently running, and each process instance is externally represented as a logical node in the distributed system, that is, the original system uses one CPU physical node as a service node to expand into multiple logical service nodes, and one CPU physical node externally represents Multiple logical service nodes, and multiple logical service nodes back up each other. In this way, the number of business nodes in the distributed system can be increased without adding physical equipment, and the processing capacity can be fully utilized to provide business capacity under the investment of the same physical equipment, so as to achieve the purpose of reducing costs. ...

Abstract

The invention discloses a service node backup method and a distributed system. Wherein, the service node backup method comprises following steps: a network management device processes to deploy for a mapping relationship between each physical processing unit in the distributed system and each logic service node, wherein, each physical processing unit exists the mapping relationship with at least one logic service node and each logic service node exists the mapping relationship with at least two logic service nodes; and each physical processing unit existing the mapping relationship with the same logic service node concurrent runs all service application program of the logic service node existing the mapping relationship with the physical processing unit. The invention can give full play to system hardware processing ability so as to improve system processing ability, at the same time cannot damage communication system safety backup mechanism.

Description

technical field [0001] The invention relates to the communication field, and more specifically relates to a service node backup method and a distributed system. Background technique [0002] In the Code Division Multiple Access (CDMA) mobile communication system, the Mobile Switching Center Emulation (MSCe) is a service control network element that adopts a distributed and node superposition mode to meet different system capacities. Each service processing node module (SMP) in the MSCe handles system traffic of a certain capacity, and the system capacity increases linearly with the increase of the number of service processing node modules. At the same time, considering the high requirements of the communication system on equipment reliability, in the original system design, each SMP module adopts the mode of active and standby physical single boards to avoid single point of failure. In the idling state, resources are seriously wasted. [0003] With the increasingly fierce ...
