Abstract:
A method for improving routing distribution within an internet through next hop selection between routers (R) identified by their respective IP addresses to direct data traffic from a source (S) identified by a source IP address and a source port identification to a destination (T) identified by a target port identification, said method including:determining equivalent routes toward the destination (T) host, each of said equivalent routes being defined by next router (R) IP address; performing a first predefined logical operation between said source (S) IP address, S port identification and T port identification to derive therefrom a connection identifier (H0); performing a second predefined logical operation between H0 and each next equivalent route R IP address, to derive next hop selection identifiers therefrom; and selecting the next hop based on a predefined criterion among said selection identifiers; wherein said equivalent routes determination is based on using conventional Routing Information Protocol (RIP) and wherein said first predefined logical operation includes:aggregating said source (S) and destination (T) ports identifications into a single word (M1); and, performing a logical XOR operation between said word M1 and the word M2 representing the source (S) IP address to derive said connection identifier (H0).
