METHOD AND DEVICE FOR POLICY BASED ROUTING

摘要

A method and a device for policy based routing. The method comprises: setting interfaces of router(s) to be multiple redirection groups, the redirection groups being ordered according to a priority order; detecting interface states of interfaces in the redirection groups; and switching traffic among the multiple redirection groups according to the interface states of the interfaces in the redirection groups. With the adoption of the method and the device of the embodiments of the present disclosure, paths passing through other operators may be optionally preferred and operating costs are saved; and moreover, by configuring multi-level policy based routing, the reliability of data transmission is enhanced, and the networking of the operator is more flexible.
