backhand
Load balancing for the Apache web server

What is mod_backhand?
mod_backhand is project that allows seamless redirection of HTTP
requests from one web server to another. This redirection can be used
to target machines with under-utilized resources, thus providing
fine-grained, per-request load balancing of web requests.
Backhand is a project that was initiated in class at The Johns Hopkins
University in The Department of Computer Science. After a simple proof
of concept, written in C++, the project was pursued as a graduate
qualifier project.
A proof of concept was realized, but a deployable product was needed.
In order for public use, testing and, ultimately, acceptance, we wished
to provide drop-in functionality in the most popular web server on the
net.
mod_backhand was born. This drop-in module for the Apache Web Server
provides a turnkey solution for intra-cluster redirection of HTTP on a
per-request basis. The redirection is based on various system resources
available within the cluster. This service is provided seamlessly,
preserving remote host information for access/authentication purposes.
As with the methodology of Apache, the redirection mechanism can be
enabled or disable for individual directories.
System resources are announced by the module to the cluster via
ethernet broadcasts and/or IP multicasts. These resources are made
available to the decision making algorithms that drive mod_backhand.
