Sensing of human motion is very important for humancomputer interactive applications such as virtual reality, gesture recognition, and communication. A vision system is suitable for human-computer interaction since this involves passive sensing and the system can estimate the motion of the user without any discomfort for the user. In this paper, we propose(More)
A powerful path computation element is a must for the next-generation IP-over-Optical networks to support ondemand service provisioning crossing layers. The main purpose of path computation in multi-layer networks (MLN) is to enable traffic engineering (TE) under a multitude of constraints. A common objective of such traffic engineering is to minimize(More)

This paper describes a multi-layer network management system for an IP/MPLS/GMPLS network, which provides integrated control and management from a packet to a lambda, even under a multi-vendor environment. The developed proto-type NMS successfully demonstrated such integrated topology management and hierarchical resource management of IP flow, MPLS LSPs and(More)
Today's ICT system necessarily involves multiple system domains complying with different management models. Integration of domain-specific management models is required to achieve, for example, agile fault localization in a huge ICT system, but this has not been efficiently achieved due to the difficulty in bridging multiple management models. To address(More)
Dynamic path computation and optimization is very challenging for emerging Multi-Layer Networks (MLN), typically Packet Optical Transport Networks (P-OTN). In this work, we propose to address a category of dynamic optimization problems in MLNs by using an M-concurrency path computation approach. By leveraging our previous work in single path computation(More)
