Steps d: judge the reconstruct resource situation: the member agency judges whether the reconstruct resource of software component running environment can support this reconstruct; If do not support, then return the information that resource does not meet the demands, then execution in step i to the restructural management platform; If support, then execution in step e;
Step e: the code of receiving member: the member agency receives the routing protocol software piece code that the restructural management platform issues;
Step f: dispose member: the member agency starts the routing protocol software member according to software reconfiguration description document and component description file in software component running environment;
Step g: feedback reconstruction result: whether reconstruct is successful for member agency inspection routing protocol software member, and returns the feedback reconstruction result to the restructural management platform; If unsuccessful, execution in step i; If success, execution in step h;
Step h: data are switched: network data is switched in the routing protocol software member after the reconstruct;
Step I: finish.
