AS65002
Intermediate AS that consists of a BGP speaker (R2) that announces 20.0.0.0/8 and its purpose is to add an additional hop to the AS-PATH so that the protected AS can be hijacked. Although in the demo the attacker announces the exact prefix that belongs to the protected AS and not a more specific one, due to the shortest path attribute of the BGP best path selection algorithm, is able to steal the traffic.AS65003
Hijacker AS that consists of a BGP speaker (R3).R3: By announcing the prefix of the protected AS (40.0.0.0/8) from this BGP speaker, we trigger a BGP hijack, and all traffic generated from AS65001 and directed towards AS65004, will be redirected to the network of AS65003.
AS65004
Protected AS that is employing ONOS. It consists of a BGP speaker, an OVS switch, a host and the ONOS instance.R4: BGP speaker announcing 40.0.0.0/8. It is connected with his neighbor through the OVS switch which is configured by the SDN-IP application to talk with the BGP speaker of AS65002.
OVS: Talks with ONOS on a management interface via 192.168.0.0/24.
ONOS: ONOS is connected with the BGP speaker to retrieve the BGP routing table. Also, it receives the BGP update messages from the ExaBGP router. Also, it has a link with the OVS switch in order to interact with the data plane.
- H4 / 40.0.0.100: Host that receives traffic with the help of the reactive-routing application from the host in AS65001.
