Dynamic mapping of nodes responsible for monitoring traffic of an evolved packet core

A control processing node comprising:

• a processor;
• and
• a memory that includes instructions for processing session traffic exchanged between a control plane and a user plane via an interface;
• wherein the instructions, when executed by the processor, cause the control processing node to:
• obtain a packet that traversed the interface,
• examine a data structure to identify an entry that identifies a user processing node whose address matches a destination address of the packet, and
• transmit a flow instruction to the address of the user processing node whose address matches the destination address of the packet, the flow instruction indicating how incoming user traffic received by the user processing node should be handled.

A non-transitory storage medium with instructions stored therein, execution of which by a processor of a control processing node causes the control processing node to perform operations comprising:

• identifying a plurality of user processing nodes with which the control processing node is able to exchange session traffic via an interface;
• populating a data structure by associating each user processing node of the plurality of user processing nodes with a different address representative of a different location along the interface;
• and
• storing the data structure in the non-transitory storage medium.
