Abstract:
1. A distributed computer system comprising a group of nodes, said group of nodes having a first and a second node adapted to act as current monitor nodes, each node of the group of nodes having an identifier and a management layer being informed which node currently acts as the current monitor node, each first and second node comprising: a protocol server adapted to associate and to send an address to a node requesting an address in the group of nodes, wherein the protocol server of the current monitor node is adapted to permanently associate an address to a node requesting an address, wherein the protocol server is adapted to liberate the permanently associated address when the management layer of the current monitor node detects as down said node, and wherein the protocol server of the current monitor node is adapted to associate a first address to a first link of a node and to associate a second address to a second link of this node, first and second addresses comprising four octet having three identical octet to designate the same node, the fourth octet being adapted to designate the first and second links; a memory adapted to store an association address-identifier of a node requesting an address; wherein the protocol server of the current monitor node is further adapted to designate an association of address-identifier of a node in the list to permit manual change of the identifier in case of change of the identifier of said node; wherein the protocol server of the current monitor node is adapted to associate a third address to a node comprising four octet with three identical octet to first and second addresses, said third address indicating first and second addresses are used in a redundant manner; and wherein the protocol server being further capable of,
