| Abstract: | Realizing options forwarding path by using policy-based routing（PBR） technology can effectively address the multi-outlet load balance problem.Through constructing access control lists and policy routing at the border router to distribute traffic and make address translation,the speed of access Internet of internal local area network users and access Intranet of Internet users was improved,with increasing internal network security under rational use of network resources. |
