FIELD: communication technologies.
SUBSTANCE: invention discloses a method and an apparatus for determining a communication line for forwarding a service flow and a data medium. Technical result is achieved by determining, based on the communication lines throughput matrix, the identification information of the first service flow and the communication lines statuses corresponding to the N communication lines, a first communication line for forwarding a first service flow of N communication lines. In embodiments of the invention, the hashing operation does not need to be performed based on the device identifier of each forwarding device, and the specific forwarding device that performs forwarding does not need to determine the plurality of hash values by comparison.
EFFECT: reduced volume of calculations and increased efficiency.
