Abstract
A method and system for providing a fault tolerant access between network clients and a network server. Accordingly, a preferred embodiment of the present invention, a first primary input/output process (IOP) and a second backup IOP are provided in a first network client. A first backup IOP and a second primary IOP are provided in a second network client. The first backup IOP is a backup of the first primary IOP and the second backup IOP is a backup of the second primary IOP. A first preferred access path between the first primary IOP and the network server as well as a first alternate access path between the first backup IOP and the network server are defined. Similarly, a second preferred access path between the second primary IOP and the network server as well as a second alternate access path between the second backup IOP and the network server are defined. A first network connection between the first primary IOP and the network server is established via the first preferred access path. If the first network connection fails, a first alternate network connection between the first backup IOP and the network server is established via the first alternate access path. In addition, a…
