1. An apparatus comprising:

  • a non-transitory memory storing instructions; and

    one or more processors in communication with the non-transitory memory, wherein the one or more processors execute the instructions for;

    receiving, by a second node from a first node, a transmission control protocol (TCP)-variant packet in advance of a TCP-variant connection being established;

    detecting an idle time period parameter field in the TCP-variant packet;

    identifying metadata in the idle time period parameter field for an idle time period and, during which, no packet is communicated in the TCP-variant connection to keep the TCP-variant connection active; and

    modifying, by the second node and based on the metadata, a timeout attribute associated with the TCP-variant connection.
