Method For Establishing Hard Pipe in Network, And Method And Apparatus for Forwarding Packet in Network

摘要

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.

1. A method for establishing a hard pipe stratum in a network, wherein the network comprises multiple routers and a network management system, adjacent routers of the multiple routers are connected to each other by using a link that has a particular bandwidth, the multiple routers form a network topology by using the link, and the method comprises:
acquiring, by the network management system, bandwidths of a plurality of links in the network; instructing, by the network management system, a router in the network topology to allocate a fixed bandwidth from a bandwidth of the link of the network topology, wherein 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, wherein the hard pipe stratum is a subtopology of the network topology, and the hard pipe stratum is used to carry a leased line service; and allocating, by the network management system, a static Multiprotocol Label Switching (MPLS) label set to the hard pipe stratum, wherein the static MPLS label set is used to forward, in the hard pipe stratum, the leased line service.
