Edge Mobility Architecture — Routeing and Hand-off
Tóm tắt
This paper presents a network architecture for supporting edge mobility, and goes on to consider IP networks in which the core topology is fixed but where the hosts at the edge of the network may be mobile, as is the case in cellular networks. Within this architecture, mobile enhanced routeing (MER) protocols are used to support the prefix-routed requirements of the fixed Internet, along with the movement of IP addresses allocated to mobile nodes. Specific components for the support of such edge mobility (EMA:MER) are then outlined; these offer fixed/mobile IP network convergence, homogeneous IP handoff across heterogeneous access technologies, and inter-domain roaming across heterogeneous large-scale IP domains.
