5 Copyright (c) 2006 IBM, released under EPL version 1.0 Architecture RSE has three major layers 1. Service Layer 2. Subsystem Layer 3. UI Layer Services Subsystems UI

6 Copyright (c) 2006 IBM, released under EPL version 1.0 Service Layer headless, barebones API layer used to interact with different protocols to provide remote services Service layer model objects are minimal and UI- independent examples: File Service File Service for listing, modifying, copying, and transferring remote file and folders Shell Service Shell Service for launching remote shells and interacting with the associated IO Process Service Process Service for listing remote processes for listing remote processes

7 Copyright (c) 2006 IBM, released under EPL version 1.0 Service Layer cont. There can be many different implementations for a given service type depending on what host services are available For example, the following are possible File Service implementations: For example, the following are possible File Service implementations:FTPDatastoreSSHHTTPLocal

8 Copyright (c) 2006 IBM, released under EPL version 1.0 Subsystem Layer Subsystems integrate the services of the service layer with connection information, model artifacts and persistence Subsystem layer model objects wrapper serivce layer objects and reference higher-level RSE objects Each subsystem associated with one service type Examples: Examples: File service subsystem Shell service subsystem Process service subsystem

9 Copyright (c) 2006 IBM, released under EPL version 1.0 Subsystem Filters Each type of subsystem may optionally provide filter support Filters are persistent objects that provide means to query specific sets of information from a host Filters are persistent objects that provide means to query specific sets of information from a host RSE provides support for persisting and managing the filters RSE provides support for persisting and managing the filters

10 Copyright (c) 2006 IBM, released under EPL version 1.0 Subsystem Configurations each subsystem configuration registered against one or more system types each subsystem configuration registered against one or more system types each host connection has the subsystems that were registered with its system type each host connection has the subsystems that were registered with its system type

11 Copyright (c) 2006 IBM, released under EPL version 1.0 Configuring Subsystems When more than one subsystem configuration for a subsystem type, user can switch configurations as desired

12 Copyright (c) 2006 IBM, released under EPL version 1.0 File Service Subsystem Configurations In this example, the current file subsystem configuration uses Datastore
