System, method and computer program product for network function modification

A computer program product modifying a network function in a connection-oriented session, the computer program product comprising a non-transitory computer-readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform:

• terminating the connection-oriented session between a client and a server via at least two proxies;
• and
• running a multipath connection-oriented session between the at least two proxies;
• wherein modifying comprises inserting the network function in the connection-oriented session, and
• wherein, if an insertion request is received, establishing a first multipath subflow with the new multipath subflow traversing the network function of the insertion request.

A system modifying a net irk function in a connection-oriented session, said system comprising:

• a processor;
• and
• a memory, the memory storing instructions to cause the processor to perform:
• terminating the connection-oriented session between a client and a server via at least two proxies;
• and
• running a multipath connection-oriented session between the at least two proxies,
• wherein the modifying comprises inserting the network function in the connection-oriented session, and
• wherein, if an insertion request is received, establishing a first multipath subflow with the new multipath subflow traversing the network function of the insertion request.
