AUTONOMIC MONITORING FOR WEB HIGH AVAILABILITY

摘要

A method for maintaining a high availability data transmission and processin g environment. A network of clusters is provided. 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 o f 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 o ne server in a second cluster of the pair of clusters via a communication link. Provided is a control server adapted 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 i n each cluster via a communication channel between the control server and the at least one server.
