Method for the exchange of data between nodes of a server cluster, and server cluster implementing said method

A method for the exchange of data between nodes of a server cluster comprising a plurality of nodes interconnected together by a geographic interconnection network comprising a plurality of transmission segments linking the plurality of nodes together according to a predetermined limited number of several different connection directions respectively associated with several different coordinates of a system of coordinates, each transmission segment of the geographic interconnection network thus belonging to a single one of the different connection directions and the system of coordinates thus being defined such that each coordinate of the system of coordinates is associated with a single one of the different connection directions, the method comprising:

• sending, by a sending node, data intended for at least one other receiving node;
• transmitting said data using the geographic interconnection network;
• and
• receiving said data by each said receiving node,
• wherein the data is supplied to each said receiving node with information relating to all of the transmission segments of the geographic interconnection network traversed between the sending node and said receiving node on transmission thereof,
• wherein said information is defined in said system of coordinates using one counter for each said connection direction, said counter being incremented or decremented when a corresponding transmission segment of said transmission segments of the geographic interconnection network, linking two nodes in the connection direction that corresponds to said counter, is traversed by the data on transmission thereof from said sending node to said receiving node.

A server cluster comprising:

• a plurality of nodes interconnected together by a geographic interconnection network comprising a plurality of transmission segments linking the plurality of nodes together according to a predetermined limited number of several different connection directions respectively associated with several different coordinates of a system of coordinates, each transmission segment of the geographic interconnection network thus belonging to a single one of the different connection directions and the system of coordinates thus being defined such that each coordinate of the system of coordinates is associated with a single one of the different connection directions,
• means for transmitting, using the geographic interconnection network, data sent by a sending node, and intended for at least one other receiving node,
• means for generating information relating to all of the transmission segments of the geographic interconnection network traversed between the sending node and said at least one receiving node on the transmission thereof, wherein said information is defined in said system of coordinates using one counter for each said connection direction, said counter being incremented or decremented when a corresponding transmission segment of said transmission segments of the geographic interconnection network, linking two nodes in the connection direction that corresponds to said counter, is traversed by the data on transmission thereof from said sending node to said receiving node;
• and
• means for supplying, to the at least one receiving node said information with the transmitted data.
