“…As a solution of traffic control, we investigated the previously proposed MIR algorithm with traffic engi- neering in a MPLS network [13][14][15][16]. The key idea of MIR is to pick a path that does not interfere too much with potential future setup requests between some source-destinations pairs.…”

“…To surmount this problem, we propose a new Multicast Routing and Wavelength Assignment method choosing a link that does not interfere too much with potential future multicast session requests, called Virtual Sourcebased Minimum Interference Path Multi-cast Routing (VS-MIPMR) [13][14][15][16][17]. Our work is inspired by the previously proposed Minimum Interference Routing (MIR) algorithm with traffic engineering in a multi-protocol label switching (MPLS) network [13][14][15][16].…”

“…Our work is inspired by the previously proposed Minimum Interference Routing (MIR) algorithm with traffic engineering in a multi-protocol label switching (MPLS) network [13][14][15][16]. Moreover, in [14] Multi-Wavelength Minimum Interference Path Routing (MW-MIPR) was proposed for an extension of MIR from the viewpoint of providing an appropriate traffic-engineering scheme through efficiently utilizing wavelengths by taking into consideration the potential future network's congestion states. Using MW-MIPR, this paper provides a new Multicast Routing and Wavelength Assignment method for multicast services, which efficiently uses the wavelength resources in comparison with VS-based tree generation method.…”

Virtual Private Network (VPN) services over the Internet are gaining increased acceptance due to the economic benefits and flexibility. However, with difficulties of providing sufficient transmission capacity for value-added and mission-critical services, the Optical VPN (OVPN) deploying Dense Wavelength-Division Multiplexing (DWDM) technology has been seen as a favorable approach for realizing the future VPN services. In an OVPN, the Routing and Wavelength Assignment problem plays a key role for capacity utilization and therefore the Multicast Routing and Wavelength Assignment problem has been the dominant issue in a DWDM-based OVPN. In this paper, using Virtual Source (VS) nodes that have splitting and wavelength conversion capabilities, we propose a new Multicast Routing and Wavelength Assignment method for multicast sessions. The algorithm combines the VS-based tree generation approach with Multi-Wavelength Mini-

While the "Virtual Private Network (VPN) over Internet" is cost-effective and flexible, it suffers from the difficulty of providing adequate transmission capacity for high bandwidth services. Hence a Dense Wavelength Division Multiplexing (DWDM) based "Optical VPN (OVPN)" technology has been regarded as a good alternative for realizing the future VPN services. To improve the transparency and data rate of OVPN, it is critical to consider the problem of Routing and Wavelength Assignment (RWA) for transmission capacity utilization. This paper proposes a Prioritybased Minimum Interference Path Multicast Routing (PMIPMR) algorithm, a new routing algorithm which finds alternative routes based on node priorities and Virtual Source (VS) nodes that has both splitting and wavelength conversion, and then chooses a path that does not interfere with potential future multicast session requests when congestions occur in the network. The PMIPMR algorithm reduces blocking rate significantly and increases the wavelength utilization by avoiding congestion in future multicast session requests. We measured the performance of the proposed algorithm in terms of blocking rate and the resource utilization. The simulation results demonstrate that the PMIPMR algorithm is superior to the previous multicast routing algorithms using
