1. A data replication system comprising:
- a replication control system;
a replication gateway node configured to create a first replication tunnel between a first gateway node and the replication gateway node and a second replication tunnel between the replication gateway node and a second gateway node,a normal data path between the first gateway node and the second gateway node;
a secondary data path between the first gateway node and the second gateway node, the secondary data path including the first replication tunnel and the second replication tunnel;
wherein the replication gateway node redirects a data stream from the normal data path to the secondary data path;
a stream normalizer node connected to the replication gateway node, wherein the replication gateway node forwards the data stream to the stream normalizer node; and
wherein the stream normalizer node performs isolation, diversion, separation and reassembly of the data streams, and forwards the data stream to a downstream service.

Abstract
A data replication system of a communication network is disclosed. According to one embodiment, the data replication system includes a replication gateway node and a replication control system. The replication gateway node is configured to create a first replication tunnel between a first gateway node and the replication gateway node and a second replication tunnel between the replication gateway node and a second gateway node. The replication gateway node replicates data streams between the first gateway node and the second gateway and delivers the replicated data stream to a management node for further analysis.

13. A method, comprising:
-
creating a first replication tunnel between a serving data gateway node and a replication gateway node; creating a second replication tunnel between the replication gateway node and a packet data network gateway node; redirecting a data stream from a normal data path between the serving data gateway node and the packet data network gateway node to a secondary data path, the secondary data path including the first replication tunnel and the second replication tunnel; forwarding the replicated data streams to a stream normalizer node; and performing isolation, diversion, separation and reassembly of the data stream, and forwarding the data stream to a downstream service. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method, comprising:
-
replacing an IP address of a packet data network gateway node with an IP address of a passive replication gateway; receiving a target traffic from a serving data gateway at the passive replication gateway node, the target traffic destined for the packet data network gateway node via a normal data path; replicating a data stream for the target traffic at the passive replication gateway node; and redirecting the target traffic to the packet data network gateway via a secondary data path, wherein the packet data network gateway targets only the target traffic; forwarding the replicated data streams to a stream normalizer node; and performing isolation, diversion, separation and reassembly of the data stream, and forwarding the data stream to a downstream service.
