Address Allocation Scheme Based on Local MAC Address

摘要

Virtualization and scale expansion in cloud data center result in sharp MAC address consumption which also expose some weaknesses in MAC address. The concept of local MAC address is proposed by IEEE standards organization to solve the limitation in traditional MAC address. In order to realize the automatic allocation of the local MAC address, we put forward two address allocation schemes which is appropriate for infrastructured network and ad-hoc network respectively. Our first scheme is a centralized management scheme which needs the usage of an address allocation device, while the other one is a distributed allocation scheme which is more suitable in wireless network without infrastructures. We simulate these two schemes based on OPNET and make an analysis on them. The results shows, our two schemes are feasible in different environment.
