Remote Reference and Transport Layers

• The remote reference layer provides a Stream interface for communication between the stubs and skeletons.

  • It knows the local and remote objects and how to translate to the local and remote name space.

• The transport layer handles all the lower-level network issues.

  • It sets up a connection over a physical socket. This is not necessarily TCP/IP, but may be UDP or other network protocol.
  • It serializes objects as required.
  • It monitors the connection for signs of trouble, such as the remote server doesn¹t respond, and may throw RemoteExceptions.
