  1. (Boundary) Traffic Management Scheme Mapping Diffserv Y1221 Interoperation Between TCs NGN Traffic Management: Issues Technology = Network = Service Multiple Technologies Multiple Networks Multiple Services end end IPv6 IPv6 IP IP Ether Wireless MPLS/ATM SDH CPN/Access Backbone A Backbone B Access

  2. NGN Traffic Management API Two Virtual Controls May not Work Together. TCP(window control) UDP IP(Diffserve,IP transfer capability) MPLS Ether(Fast, Giga,) Virtual ATM(ATM transfer capability) SDH(Virtual Container) Λ(2.4G,10G,40G..) Physical Fiber(DWDM,CDWM) API will request network to provide a suitable combination of traffic controls. NGN will be adaptive so that it can respond the API’s request. NGN select suitable technologies and their traffic management scheme so That the API’s needs can be met.
