Vijay, Jan, all, I am replying this email publicly so that all of us can engage more in shaping the agenda in about three weeks.
A key item that the WG needs to discuss, in the potentially more productive f2f-meeting setting in Berlin, is how the WG should move forward. Can we allocate a slot, say at least 20 min, for this discussion? Besides the general discussions, here are some comments on specific agenda items and the mission of the WG: - Despite the substantial change of the networking landscape, I still believe that the foundational services of ALTO are sound: providing abstract network information to applications. I believe that this is also what many others see ALTO; for example see [1]. The key is what we do to go beyond the initial network abstractions. - The first I see is Endpoint Cost Service (ECS), which is the foundation. It provides an interface to allow applications to know the routing costs. However, current ALTO is defined pre-SDN, and the emerging trend of SDN is going beyond simple destination routing, to be more application dependent. Hence, I see that we need to go beyond Endpoint Cost Service, to say Flow Cost Service. There is an extension draft [2], and I suggest that the WG finishes this to make the ALTO protocol complete. Make sense? - The next I see is network graph (path vector) abstraction. The more I think about it, the more I am convinced that this is the way we go. I am an author of the draft and multiple versions are evolving [3, 4, 5], but we are relatively slow in convergence. I suggest that the WG gets a set of active participants to finish this draft, so that we have a relatively complete set of ALTO services.
