- 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.
