What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

its not in any of the delphi units, heres some of the prototypes etc:

  const
    MIB_TCP_STATE_CLOSED = 1;
    MIB_TCP_STATE_LISTEN = 2;
    MIB_TCP_STATE_SYN_SENT = 3;
    MIB_TCP_STATE_SYN_RCVD = 4;
    MIB_TCP_STATE_ESTAB = 5;
    MIB_TCP_STATE_FIN_WAIT1 = 6;
    MIB_TCP_STATE_FIN_WAIT2 = 7;
    MIB_TCP_STATE_CLOSE_WAIT = 8;
    MIB_TCP_STATE_CLOSING = 9;
    MIB_TCP_STATE_LAST_ACK = 10;
    MIB_TCP_STATE_TIME_WAIT = 11;
    MIB_TCP_STATE_DELETE_TCB = 12;

  type
    PMIB_TCPROW=^TMIB_TCPROW;
    TMIB_TCPROW = record
      dwState : LongWord; //state of the connection
      dwLocalAddr : TLongWordBytes; //address on local computer
      dwLocalPort : TLongWordBytes; //port number on local computer
      dwRemoteAddr : TLongWordBytes; //address on remote computer
      dwRemotePort : TLongWordBytes; //port number on remote computer
    end;
    PMIB_TCPTABLE=^TMIB_TCPTABLE;
    TMIB_TCPTABLE = record
      dwNumEntries : LongWord; //number of entries in the table
      table : array[0..150] of TMIB_TCPROW; //array of TCP connections
    end;

    {api declarations}
    function GetTcpTable (pTcpTable: Pointer; var pdwSize : Longword; bOrder : LongWord): LongWord;stdcall;
    function GetTcpTable; external 'iphlpapi.dll' name 'GetTcpTable';

i'm not sure how you get to see the actual data being transmitted, you probably need to hook winsock or something.
