Abstract: The present disclosure discloses a method and apparatus for establishing a hard pipe in a network. The network includes multiple routers and a network management system. The method includes: acquiring, by the network management system, bandwidths of a plurality of links in the network; instructing, a router to allocate a fixed bandwidth from a bandwidth of the link of the network topology, where a link to which the fixed bandwidth is allocated forms a sublink, and the sublink and the router that allocates the sublink form a hard pipe stratum, which is used to carry a leased line service; and allocating, a static MPLS label set to the hard pipe stratum. A service packet that has an MPLS label in the static MPLS label set is forwarded by using the hard pipe stratum, thereby ensuring that a bandwidth of the leased line service is not occupied by a non-leased line service.
