Smart filter generator

A non-transitory computer readable storage medium having stored thereon program code executable by a smart filter generator (SFG) to:

• maintain at least one mapping between:
• a first parameter found in network traffic replicated from a core network;
• and
• a second parameter related to the first parameter, wherein the second parameter is related to a user equipment characteristic not found in the network traffic replicated from the core network;
• receive a first packet filter definition comprising a filtering criterion that applies the second parameter;
• based on the at least one mapping, search for the first parameter to update the filtering criterion to apply the first parameter;
• and
• based on the updated filtering criterion, generate a second packet filter definition to communicate to a packet broker,
• wherein the packet broker is configured to apply the second packet filter definition to the network traffic, and
• wherein the at least one mapping comprises mappings between first parameters and second parameters, each of the mappings corresponding to a related group of parameters.

A computer system operating as smart filter generator (SFG) in a visibility network, comprising:

• a processor;
• and
• a non-transitory computer readable medium having stored thereon program code that, when executed, causes the processor to:
• maintain at least one mapping between:
• a first parameter found in network traffic replicated from a core network;
• and
• a second parameter related to the first parameter, wherein the second parameter is related to a user equipment characteristic not found in the network traffic replicated from the core network;
• receive a first packet filter definition comprising a filtering criterion that applies the second parameter;
• based on the at least one mapping, search the first parameter to update the filtering criterion to apply the first parameter;
• and
• based on the updated filtering criterion, generate a second packet filter definition to communicate to at least one packet broker,
• wherein the at least one mapping comprises mappings between first parameters and second parameters, each of the mappings corresponding to a related group of parameters and being stored in a separate database of the computer system.
