Sue and Robert,

When you say "..DDoS attack to I2NSF agent", do you mean the entity (such as the Admin) that issues policies to the Controller is under DDoS attack?
Each I2NSF agent and I2NSF client needs to provide application level
support for management traffic during periods of DDoS and network
security attacks to deal with congestion (burst and/or continuous),
high error rates and packet loss due to the attacks, and the
inability to utilize a transport protocol (E.g. TCP) due to a
specific protocol attack.


Are the SSLs in your draft refer to the SSL between I2NSF client and agent?

When you say APIs to application, who is issuing the APIs and who is receiving the APIs?

Thank you very much.

Linda Dunbar
