Method for optimizing traffic between autonomous systems

A method for distributing traffic across a set of links interconnecting a local autonomous system with a plurality of autonomous systems neighboring the local autonomous system, the method comprising:

• /a/ receiving information at least relating to characteristics of the plurality of neighboring autonomous systems;
• /b/ determining, from the information received, a result of a reward function, representative of a state of the set of links;
• /c/ triggering, based on the information received and the result of the reward function, at least one action influencing a distribution of traffic across the set of links so as to optimize the load state of the set of links;
• /d/ reiterating steps /a/ to /c/;
• the at least one action being identified by an artificial intelligence configured to learn to identify, on the basis of successive results of the reward function, actions enabling traffic to be distributed across the set of links so as to optimize the load state of the set of links,
• wherein the information received according to step /a/ is representative of:
• a load state of the set of links;
• a type of autonomous system for each of the neighboring autonomous systems;
• and
• prefixes relating to networks hosted by the local autonomous system and the neighboring autonomous systems, the prefixes being announced by an autonomous system to its neighbors,
• wherein the at least one action triggered according to step /c/ comprises the modification of the at least one Border Gateway Protocol (BGP) attribute, and
• wherein the modification of the at least one BGP attribute takes into consideration a propagation delay of the prefixes to be announced.
