You must be joking ...

evolution of FS. I pretty see FS evolution largely beyond DDoS domain. FS
is a very good protocol for SDN applications. The question behind is do we
really need to work with multiple address families for each type of
"service"/"interface type" to filter or do we need to have a more global
model where we would be able to put any type of filter any where and apply
multiple actions (openflow like FS). Compared to openflow, FS has the magic
to enable multipoint distribution of actions.

            CE1 DDOS Detection Appliance establishes EVPN flowspec session
with Egress PE, it detects DDOS attack traffic and generate ACL rule, the
ACL rule is announced to Egress PE through EVPN flowspec protocol, then the
egress PE announces it to ingress PE, finally ingress PE installs the ACL
rule for traffic filtering.

that it needs to deliver a FS path to the ingress PE?? It cannot come from
the CE as that is data plane learning. I would think that all FS paths have
to be disseminated by a centralized controller.
