  - sendMessage
```
java.math.BigInteger sendMessage(java.lang.String _to,
                                 java.lang.String _svc,
                                 java.math.BigInteger _sn,
                                 byte[] _msg)
```
    Sends the message to a specific network. Only allowed to be called by registered BSHs. _sn : positive for two-way message, zero for one-way message, negative for response
    
    Parameters:
    
    _to - String ( Network Address of destination network )
    
    _svc - String ( name of the service )
    
    _sn - Integer ( serial number of the message )
    
    _msg - Bytes ( serialized bytes of Service Message )
    
    Returns:
    
    Integer ( network serial number of message )
  - getFee
```
java.math.BigInteger getFee(java.lang.String _to,
                            boolean _response)
```
    Gets the fee to the target network _response should be true if it uses positive value for _sn of sendMessage(java.lang.String, java.lang.String, java.math.BigInteger, byte[]). If _to is not reachable, then it reverts. If _to does not exist in the fee table, then it returns zero.
    
    Parameters:
    
    _to - String ( BTP Network Address of the destination BMC )
    
    _response - Boolean ( Whether the responding fee is included )
    
    Returns:
    
    Integer (The fee of sending a message to a given destination network )
