Abstract: A computing system and a method are provided for determining a network traffic routing path through a service function chain (SFC). A joint network slicing and traffic engineering problem is provided that may be solved to identify network slicing configuration and traffic engineering parameters to provide a set of function nodes, the SFC, and the network traffic routing path from the source node to the destination node. The joint network slicing and traffic engineering problem P may be solved by minimizing a resource objective associated with the joint network slicing and traffic engineering problem, in accordance with a set of one or more constraints. Instructions may be transmitted to a network orchestrator to create the service function chain in a network slice on the set of network nodes in accordance with the identified network slicing configuration and traffic engineering parameters, to provide the network traffic routing path.

Abstract: A resource scheduling method and apparatus in a DSL system, and a system are provided, to reduce energy consumption of the DSL system. The method includes: determining, according to service traffic information of each subscriber line and transmission capability information of each subscriber line, a transmission opportunity initial value allocated to each subscriber line in a TDD frame; and according to the transmission opportunity initial value of each subscriber line, dividing the TDD frame into a normal operation interval and a discontinuous operation interval, determining a transmission opportunity occupied by each subscriber line in the normal operation interval, and determining a subscriber line group in the discontinuous operation interval and a transmission opportunity occupied by each subscriber line group in the discontinuous operation interval.
