- A Testbed Demonstrating Optical IP Switching (OIS) in Disaggregated Network Architectures
- The lack of a unified control plane does not allow current optical networks to dynamically provision new optical paths. The IETF standardization body has proposed the Generalized Multi-Protocol Label Switching standard as a solution to this problem. Their efforts however focus on the creation of end-to-end optical trails. This concept...

- A Novel Mechanism in MPLS Network Under Adversarial Uncertainty
- The advantage of Multi-Protocol Label Switching MPLS is its capability to route the packets through explicit paths. But the nodes in the paths may be possibly attacked by the adversarial uncertainty. Aiming at this problem in MPLS Network, this paper proposes a novel mechanism in MPLS network under adversarial uncertainty,...

- PNNI Based Control Plane for Automatically Switched Optical Networks
- Much effort has been spent on the definition of control plane protocols for Automatically Switched Optical Networks ASON. Most of the proposals brought into the standardisation for a ITU-T, IETF and OIF are based on IP concepts. One such proposal is the Generalized Multi-Protocol Label Switching GMPLS, an extension of...
