Chapter 1. Remote Control sessions overview  5
Managed Node A Tivoli Managed Node runs the same software that runs 
on a TMR Server. Managed Nodes maintain their own 
Object DataBases, which can be accessed by the TMR 
Server. When Managed Nodes communicate directly 
with other Managed Nodes, they perform the same 
communication or security operations as they would 
perform with the TMR Server. Although there is no clear 
distinction between managed systems and managing 
systems, the introduction of the Endpoints architecture 
leads to a paradigm shift. Managed Nodes are 
considered to be managing systems (hosting the 
desktop or running as a gateway), whereas endpoints 
are the managed systems.
Endpoint Manager The Endpoint Manager establishes and maintains the 
relationship between an Endpoint and its assigned 
Gateway. It is involved in taking the Endpoint in charge 
when its assigned Gateway is no longer responding. It is 
also involved in identifying the Gateways that an 
Endpoint is assigned to when applications are trying to 
contact the Endpoint. The Endpoint Manager runs on top 
of the TMR Server and is automatically created during 
the TMR Server installation process.
Endpoint Gateway The Endpoint Gateway provides access to the Endpoint 
methods and provides the communications with the TMR 
Server that the Endpoints occasionally require. A single 
Gateway can support communications with thousands of 
Endpoints and can launch methods on an  Endpoint or 
run methods on the Endpoint’s behalf. A Gateway is 
created on an existing managed node. 
Endpoint Proxy An Endpoint Proxy is an optional component that 
emulates Endpoints to the Gateway to simplify the Tivoli 
communications in a firewall environment through a 
common port. The Endpoint Proxy funnels requests for 
specific Endpoints through a single TCP/IP port and 
passes it down to a Relay or a Gateway Proxy. This 
component is part of the Tivoli Firewall Security Toolbox 
and must be installed on the same network zone as the 
Tivoli Endpoint Gateway on which it is connected.
