Adaptation of Quality of Service in Handling Network Traffic

A network device, comprising:

• an interface configured to receive a Domain Name System message;
• a memory configured to store at least one network label;
• and
• a processor configured extract a network label from a payload section of the Domain Name System message, the extracted network label identifying a network resource, to compare the extracted network label to the at least one stored network label, and to initiate, on the basis of the comparison, adaptation of a quality of service level for a forwarding treatment of data packets communicated with the network resource.

A non-transitory computer-readable medium which has an executable computer program product stored thereon, the computer program product comprising program code to be executed by a processor of network device, thereby causing the network device to operate as follows:

• receiving a Domain Name System message;
• extracting a network label from a payload section of the Domain Name System message, the extracted network label identifying a network resource;
• comparing the extracted network label to at least one stored network label;
• and
• on the basis of the comparison, initiating adaptation of a quality of service level for a forwarding treatment of data packets communicated with the network resource.
