Abstract
This paper focuses on important issues pertinent to future networks, i.e. future network application trend, Network Model, and NGN development strategies. The authors challenge the orthodox OSI/RM and Internet architectural representation with a point of view that it does not explain modern network operation satisfactorily and is unable to cope with service oriented trend in network computing. By re-clarifying out-of-band signaling concept in the context of networking, this paper provides an architecture representation of Internet and introduces an ONAS/RM (Open Network Application Service/Reference Model) for future networks. With regard to NGN development strategy, this paper promotes a “BSF-OES” (Backbone Substrate First, Outwards Expansion Second) strategy, in contrast to “add-on” approaches widely adopted in standards organizations and to those termed by layer-less architecture. Finally, a framework of SUPANET (Single-layer User-data switching Platform Architecture Network), developed at SC-Netcom Lab, is used to demonstrate feasibility of such strategy and how to cope with technical challenges, to protect investments, and to make smooth migration to future networks.
