The traffic type detector extracts a network label, e.g. a domain name, a hostname, or a network address, from the message and compares this extracted network label to one or more stored network labels. On the basis of the comparison, adaptation of a quality of service level for a forwarding treatment of data packets associated with the message is initiated, e.g. by controlling a bearer used for communicating the data packets. ## Claims ### Claim 1 A method of handling network traffic, the method implemented by a network device comprising the steps of: 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. ### Claim 2 (depends on 1) The method according to claim 1, further comprising the step of: identifying a node communicating the data packets on the basis of a network address included in the Domain Name System message. ### Claim 3 (depends on 1) The method according to claim 1, further comprising the steps of: receiving a further message in response to which the Domain Name System message is generated; and identifying a node communicating the data packets on the basis of a network address included in the further message. ### Claim 4 (depends on 1) The method according to claim 1, wherein said adaptation of the quality of service level comprises controlling a bearer used for communicating the data packets. ### Claim 5 (depends on 4) The method according to claim 4, wherein said controlling of the bearer comprises initiating modification of an existing bearer. ### Claim 6 (depends on 5) The method according to claim 5, wherein the existing bearer is returned to its state before modification in response to a triggering event. ### Claim 7 (depends on 4) The method according to claim 4, wherein said controlling of the bearer comprises initiating establishment of a dedicated bearer to carry the data packets. ### Claim 8 (depends on 7) The method according to claim 7, wherein the dedicated bearer is deactivated in response to a triggering event. ### Claim 9 (depends on 4) The method according to claim 4, further comprising the steps of: extracting a network address from the Domain Name System message; and initiating generation of a packet filter operating on the basis of the extracted network address, the packet filter being configured to route the data packets to the bearer. ### Claim 10 (depends on 4) The method according to claim 4, further comprising the steps of: receiving a further message generated in response to the Domain Name System message; extracting a network address am the further message; and initiating generation of a packet filter operating on the basis of the extracted network address, the packet filter being configured to route the data packets to the bearer. ### Claim 11 (depends on 4) The method according to claim 4, further comprising the steps of: receiving a further message in response to which the Domain Name System message is generated; extracting a network address from the further message; and initiating generation of a packet filter operating on the basis of the extracted network address, the packet filter being configured to route the data packets to the bearer. ### Claim 12 (depends on 1) The method according to claim 1, wherein the network label is a domain name and the Domain Name System message is a Domain Name System query for a network address associated with the domain name. ### Claim 13 (depends on 1) The method according to claim 1, wherein the network label is a domain name and the Domain Name System message is a response to a Domain Name System query for a network address associated with the domain name. ### Claim 14 (depends on 1) The method according to claim 1, wherein the network label is a network address and the Domain Name System message is a response to a Domain Name System query for the network address. ### Claim 15 (depends on 1) The method according to claim 1, wherein the network label is a hostname and the Domain Name System message is a Hypertext Transfer Protocol request to a server which can be identified through the hostname. ### Claim 16 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. ### Claim 17 (canceled) ### Claim 18 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.
