Abstract: In general, this disclosure describes usage monitoring techniques. In one example, a method comprises storing, by a monitoring device that performs usage monitoring for at least one packet flow that traverses an access network by which subscriber devices access a packet data network, data indicating an amount of unused granted service units for the at least one packet flow that is unused as of a policy rule deactivation time for one or more policy rules matched by the at least one packet flow. The monitoring device further reactivates the usage monitoring for the at least one packet flow at a policy rule reactivation time for the one or more policy rules matched by the at least one packet flow based on an updated amount of granted service units, wherein the updated amount of granted service units are based on the data indicating the amount of unused granted service units.

Abstract: A network device includes one or more processors configured to use a fat flow rule that specifies at least one of a mask to be applied to source Internet protocol (IP) addresses or to destination IP addresses, or that source ports or destination ports are to be ignored. The one or more processors may further be configured to receive packets having different source or destination IP addresses and/or different source or destination ports, and nevertheless assign the packets to the same fat flow according to the fat flow rule, e.g., by masking the source or destination IP addresses and/or ignoring the source or destination ports of the packets. In this manner, the network device may aggregate two or more different flows into a single fat flow.

Abstract: In one example, a gateway device includes one or more processors configured to determine that a subscriber device has started a first application, determine that the subscriber device has ended a second application, and send a message, in accordance with Diameter protocol, to a policy server device indicating both that the subscriber device has started the first application and that the subscriber device has ended the second application. In another example, a gateway device includes one or more processors configured to send at most one message, in accordance with Diameter protocol, to a policy server device indicating that a subscriber device has started an application, and at most one message, in accordance with the Diameter protocol, indicating that the subscriber device has stopped the application.

Abstract: The disclosed apparatus may include a storage device that stores at least one policy for handling certain network traffic exchanged between multiple computing devices during at least one specific day. The apparatus may also include a policy-enforcement unit communicatively coupled to the storage device. The policy-enforcement unit may receive, at a network device that facilitates network traffic within a network, at least one packet to be exchanged between the multiple computing devices on the specific day. The policy-enforcement unit may then determine, due at least in part to receiving the packet on the specific day, that the policy applies to the packet. In response to determining that the policy applies to the packet, the policy-enforcement unit may handle the packet in accordance with the policy. Various other apparatuses, systems, and methods are also disclosed.
