Federated Routing Scheme for Large-scale Cross Domain Network

With the development of multi-network integration, how to ensure interconnections among multiple independent network domains is becoming a key problem. Traditional interdomain routing protocol such as BGP (Border Gateway Protocol) or SR (Segment Routing) fails due to the limitation of information island (data privacy), where each autonomous network domain does not share any specific intra-domain information. In this poster, we propose a federated routing scheme FRP, which realizes global routing without any intra-domain data. Each domain only needs to exchange the very lightweight cumulative gradients of overlapped parameters to build the federated routing model. With FRP, flows between any pair of nodes can get global optimal routing results no matter which domain the source and destination nodes locate.
