Question

What is the difference between LLA and HLA in details?

 

Answer

The SiteMinder framework agents break the Web Agent’s access control functionality into logical blocks, called managers.

Managers are assigned specific tasks and are controlled by a single High-Level Agent (HLA) manager that implements the logic of SiteMinder access control.

The High Level Agent orchestrates the complete flow of servicing a request, from receiving the request to finally authorizing access to the requested resource.

The Low Level Agent Worker Process (LLAWP) implements the Agent-to-Policy Server DoManagement polling mechanism as well as writing log messages to the physical log medium and collating health data for the SiteMinder One-View Monitor. The Low Level Agent Worker Process uses shared memory to communicate between clients, and to facilitate logging and caching.
