Subject: OpenCluster v 0.2 - High-Availability and Load Balancing Software

Dear Sir/Madam,

OpenCluster v 0.2 is a new revolutionary software for Linux distributed 
under GNU GPL license agreement. Quantizer v. 0.2 implements Quantum 
Balancing algorithm for master-less load-balancing distributed with 
OpenCluster as well as Pulsar v. 0.7 - master-less high-availability 
software with fast failover detection.

Download the latest version of Open Cluster distribution from:
http://www.vitaesoft.com/registered/OpenCluster.zip

The main goal of proposed software is to implement reliable ip-cluster 
solution where cluster itself consists of similar computers.  The cluster 
can be used for implementing high availability and/or load balancing of 
each service. All the computers are located on one ethernet-based local 
net and have the same ip address (VIP - "virtual ip address", according to 
LVS terminology). All computers see all the requests coming from user 
side. Selection is based on client's address. Every computer serves only 
users, whose ip-address belongs to particular address range. If one or 
some number of clustered computers fails, the other will take their users.  
We provide our own heartbeat code. Every computer in the cluster sends 
information reporting its health to all other computers. Based on 
predefined timeouts the decision is made whether particular computer 
(and/or service) is working or not. This information is used to generate a  
rule for iptables filter. The information can be send using the same 
ethernet interface which serves clients requests.

Best regards,
Vitaly
