Abstract: A system for detecting a computing device tethered to a mobile device is described. The system includes communicatively coupled the computing device to the mobile device with an IPv4 domain protocol. Additionally, the mobile device is communicatively coupled to the mobile data network with an IPv6 domain protocol. A network module, associated with a mobile data network, receives a DNS request packet from the mobile device. An IPv6 hostname and an IPv6 destination address is associated with the DNS response packet, when the DNS response packet is associated with the IPv6 address. Additionally, an IPv4 hostname and an IPv4 destination address is associated with the DNS response packet, when the DNS response packet is associated with the IPv4 address. A communication packet, generated by the mobile device, is also received by the network module. The communication packet includes a destination address and a hostname.

Abstract: Embodiments of the present invention include approaches for selecting a routing path of a data set from its source to its destination on a network and allocating a network cost for delivering the data set. The approaches include collecting traffic information on the network, determining one or more routing paths from the source to the destination, computing network cost(s) associated with the routing path(s), selecting a routing path based on the associated network costs, a flow value associated with the data set, and the collected traffic information, and allocating the network cost to network users in accordance with a cost policy.
