Abstract

Various embodiments manage data flow between at least one wireless communication device and at least one application executing at an edge of the wireless communication network. In one embodiment, a first flow regenerator disposed within the network generates a replicated set of data packets. The replicated set of data packets are a copy of a set of data packets being transmitted between an application disposed on a first node at an edge of the network and a wireless communication device. The first flow regenerator sends the replicated set of data packets to a second flow regenerator disposed in the network. The replicated set of data packets are sent to the second flow regenerator through at least a second node disposed between the first flow regenerator and the second flow regenerator. The second node is configured to perform one or more book-keeping operations on the replicated set of data packets.

First claim

1 - 7 . (canceled)

sending, by the first flow regenerator, the replicated set of data packets to a second flow regenerator disposed in the wireless communication network, the replicated set of data packets being sent to the second flow regenerator through at least a second node disposed between the first flow regenerator and the second flow regenerator, where the second node is configured to perform one or more book-keeping operations on the replicated set of data packets.

15 . The computer program product of claim 14 , the method further comprising:
changing, by the first flow regenerator, at least one characteristic of the replicated set of data packets, where the at least one characteristic that is changed indicates to the second flow regenerator that the replicated set of data packets is to be removed from the wireless communication network.

16 . The computer program product of claim 14 , wherein the first node is a base station.

17 . The computer program product of claim 14 , wherein the set of data packets are being transmitted from the wireless communication device to the application.

18 . The computer program product of claim 14 , wherein the set of data packets are being transmitted from the application to the wireless communication device.

19 . The computer program product of claim 14 , the method further comprising:
receiving, by the second flow regenerator, the replicated set of data packets; analyzing, by the second flow regenerator, the replicated set of data packets; determining, by the second flow regenerator, that the at least one characteristic of the replicated set of data packets has been changed by the first flow regenerator; and removing, by the second flow regenerator, the replicated set of data packets from the wireless communication network.
