Abstract
Under the present invention, when a TCS receives a data command (e.g., a read or write command) pursuant to a communication session between the TCS and an application, it will first request permission from a permission system to execute the data command. By applying a set of rules to a setting of a state variable associated with the TCS, the permission system will determine whether to grant the permission. If so, the TCS will execute the data command and change the setting of the state variable. If a close command is later received by the TCS to close the communication session, permission will once again be requested from the permission system, which will again apply a set of rules to the current setting of the state variable to determine if the session can be safely closed.
