Abstract
OVPN over IP/GMPLS over DWDM technology with QoS assurances is considered as a promising
approach for the next generation OVPN. In this paper, we suggest a multicast OLSP (Optical Label
Switched Path) establishment mechanism for supporting high bandwidth multicast services in
OVPN over IP/GMPLS over DWDM. For the establishment of the multicast OLSP, we propose a new
multicast tree generation algorithm VS-MIMR that finds the minimum interference path between
virtual source nodes. We also suggest an entire OVPN control mechanism to adapt the operation of
the routing and signaling protocols of GMPLS.
