Abstract: A congestion control method and apparatus is disclosed. The method includes, when usage information of a buffer in a device satisfies a preset first condition, determining at least one first queue from the buffer, and performing congestion control on the at least one first queue, where the first condition includes a first threshold corresponding to the usage information of the buffer, and the at least one first queue is a queue whose queue delay is greater than or equal to a queue delay threshold or whose queue length is greater than or equal to a queue length threshold in a plurality of queues in the buffer. In this way, the device triggers a condition of congestion control based on a buffer status.

Abstract: The present application provides an HQoS control method, where the RSG is connected to multiple CSGs, and each CSG of the CSGs is connected to multiple base stations. The RSG configures a bandwidth limitation parameter for each CSG; creates different AAA domains for different IP address network segments, and configures a QoS scheduling parameter in each AAA domain; and determines, according to a configuration parameter of a first base station, a bandwidth limitation parameter of a CSG connected to the first base station, and determines a QoS scheduling parameter of the first base station, where the configuration parameter is used to indicate the CSG connected to the first base station and an AAA domain corresponding to the first base station. The present application greatly migrates a risk from excessively concentrated base station gateways, and ensures that a service packet securely traverses a layer 2 tunnel of a fixed network operator.

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.
