OBJECTIVES The key objective for this white paper is to provide an update on progress since we published the first joint-operator white paper on Network Functions Virtualisation in October 2012 and initiated the Network Functions Industry Specification Group (NFV ISG) under the auspices of the European Telecommunications Standards Institute (ETSI). [1] This(More)
— A powerful path computation element is a must for the next-generation IP-over-Optical networks to support on-demand 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)
Sensing of human motion is very important for human-computer 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)
SUMMARY Sensing of human motion is very important for hu-man–computer 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.

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)
A seamless end-to-end call set up over multi-carrier ASON and GMPLS network domains was successfully achieved. Interworking of two ASON network domains and five GMPLS network domains was demonstrated on a nationwide scale. 1. Introduction Generalized Multi-Protocol Label Switching (GMPLS) [1] is a set of network control protocols to envision a next(More)
OBJECTIVES This is a non-proprietary white paper authored by network operators. The key objective for this white paper is to outline the benefits, enablers and challenges for Network Functions Virtualisation (as distinct from Cloud/SDN) and the rationale for encouraging an international collaboration to accelerate development and deployment of interoperable(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)
