Research on the Satellite Networks Management Based on Policies

According to structure feature of satellite network management, the global policy servers and the local policy servers have been established. Function modules of satellite networks were designed on the base of system architecture, such as policy management tools, policy library, policy decision point and policy execution point, etc. The policy description method based on XML has been implemented and policy decision point LDAP communication module and COPS communication module have been intensive studied. The policy transmission has been implemented among the policy management tools, the policy library and policy decision poinst through LDAP module and the transmission between the policy decision points and policy implementation points were also implemented by COPS.
