Concur. ALTO is currently used in support of P2P and CDN operation. It has the functionality to query the network topological data. However that's where the similarity with SDN ends. Running them together, how are they inter-related? Also you have brought up the concept of SDN Domains. What are they? Who owns them? Why do we need them? For scaling? For admin? If for scaling, SDN controller intrinsically has no scaling problem per sa. For admin, SDN is to offer an overlay architecture on top of the network with a uniformed view from application perspective, which is opposite of having some sort of peering models. Please elaborate your thoughts. On Sun, Mar 25, 2012 at 12:52 PM, ZongNing <zongning@huawei.com> wrote: > Hi, Tina, > > Very interesting topic!
