SYSTEM FOR AUTONOMIC MONITORING FOR WEB HIGH AVAILABILITY
First Claim
1. A system for maintaining a high availability processing environment, said system comprising:
- a network having a plurality of clusters, each cluster of the network comprising a plurality of identical servers, each cluster of the network being directly connected to at least one other cluster of the network, wherein each pair of clusters directly connected to each other is characterized by each server in a first cluster of the pair of clusters being directly connected to at least one server in a second cluster of the pair of clusters via a communication link; and
a control server configured to monitor an operational status of said communication link, said operational status of the communication link being that said communication link is operational or non-operational, said control server being directly linked to each server of at least two servers in each cluster via a separate communication channel between the control server and each server of the at least two servers in each cluster, wherein there is no coinciding path segment among the separate communication channels between the control server and each server of the at least two servers in each cluster.

Abstract
A system for maintaining a high availability data transmission and processing environment. The system includes a network of clusters and a control server. Each cluster of the network includes at least two identical servers. Each cluster of the network is directly connected to at least one other cluster of the network. Each pair of clusters directly connected to each other is characterized by each server in a first cluster of the pair of clusters being directly connected to at least one server in a second cluster of the pair of clusters via a communication link. The control server is configured to monitor an operational status of the communication link (i.e., the communication link is operational or non-operational). The control server is directly linked to at least one server in each cluster via a communication channel between the control server and the at least one server.
