Abstract： In response to the problems of high bandwidth costs for campus network egresss and a single internet access method for teachers and students，this paper designs a set of operator proxy dialing scheme realized based on GRE tunnel and virtual private network technologies，andthescheme does notrequirechanging theoriginal topological architecture. Byconfiguring tunnel interfaces between core BRAS devices，optimizing proxy dialing processand transforming Portal authenticationsystems，deep integrationofcampus networksandoperatornetworks isachieved.Thescheme supportsteachers andstudents toindependentlyselectoperator networksandmts the demandsofmulti-networkaccessItfeaturesbotheaseof operationandcompatibility，safeguards theinterestsofsocialcapital whileunifyngusermanagement，and providesaeplicable technical path for low-cost transformation of university networks.
