Abstract

OVPN(Optical Virtual Private Network) based on DWDM(Dense Wavelength Division Multiplexing) backbone framework is considered as a promising approach for the future VPN. This paper proposes a new routing algorithm, called PMIPMR (Priority-based Minium Interference Path Multicast Routing) algorithm which finds an alternate route considering node priorities when the congestion is occurred in a network. The PMIPMR algorithm tries to improve blocking probability and wavelength utilization by avoiding congested path for potential future connection requests.
