# 7 Interfaces

The Distribution Subsystem offers interfaces for both getting data and setting parameters to the Language level. The following modules interface the DS:

- DPInit: Initialization of the DS.

- DPStatistics: Various statistics on the performance of the DS.

- Remote: Spawning remote processes.

- Fault: Handling failure in customized ways.

- Connection: Creating tickets and taking for bootstrapping connections.

There is also a set of properties that affect the behavior of the DS. These settings affect all distributed activities for the whole site so they should be used with care. They are defined in Chapter 22 of ``System Modules'' under dp and dpLog.
