    identifying a first idle time period header, in the first packet, for detecting a first idle time period during which no TCP packet including data in a first TCP data stream sent in the TCP connection from the second node is received by the first node;

    detecting the first idle time period based on the first idle time period header; and

    deactivating the TCP connection in response to detecting the first idle time period.
