Systems and methods for tracking and calculating network usage in a network with multiple user plane functions

A non-transitory computer-readable medium, storing a set of processor-executable instructions, which, when executed by one or more processors of a network device, cause the one or more processors to:

• receive traffic via a General Packet Radio Service (“GPRS”) Tunneling Protocol (“GTP”) tunnel;
• identify, without performing deep packet inspection (“DPI”), that:
• a first set of traffic, included in the traffic received via the GTP tunnel, is a first type of traffic, and
• a second set of traffic, included in the traffic received via the GTP tunnel, is a second type of traffic;
• forward, to one or more other devices and in accordance with a particular rule, only a first subset of the first type of traffic and only a second subset of the second type of traffic;
• and
• report, to a second network device of the wireless telecommunications network:
• a first amount of the first type of traffic, in the first subset, that was forwarded by the network device,
• a second amount of the second type of traffic, in the second subset, that was forwarded by the network device, and
• an indication of the particular rule that was used to forward only the first subset of the first type of traffic and only the second subset of the second type of traffic.

A method, comprising:

• receiving, by a network device, traffic via a General Packet Radio Service (“GPRS”) Tunneling Protocol (“GTP”) tunnel;
• identifying, by the network device, and without performing deep packet inspection (“DPI”), that:
• a first set of traffic, included in the traffic received via the GTP tunnel, is a first type of traffic, and
• a second set of traffic, included in the traffic received via the GTP tunnel, is a second type of traffic;
• forwarding, by the network device, to one or more other devices, and in accordance with a particular rule, only a first subset of the first type of traffic and only a second subset of the second type of traffic;
• and
• reporting, by the network device and to a second network device of the wireless telecommunications network:
• a first amount of the first type of traffic, in the first subset, that was forwarded by the network device,
• a second amount of the second type of traffic, in the second subset, that was forwarded by the network device, and
• an indication of the particular rule that was used to forward only the first subset of the first type of traffic and only the second subset of the second type of traffic.
