In the IPTV systems, multicasting will play a crucial role in the delivery of high-quality video services, which can significantly improve bandwidth efficiency. However, the scalability and the signal quality of current IPTV can barely compete with the existing broadcast digital TV systems since it is difficult to implement large-scale multicasting with end-to-end guaranteed quality of service (QoS) in packet-switched IP network. China 3TNet project aimed to build a high performance broadband trial network to support large-scale concurrent streaming media and interactive multimedia services. The innovative idea of 3TNet is that an automatic switched opticalnetworks (ASON) with the capability of dynamic point-to-multipoint (P2MP) connections replaces the conventional IP multicasting network in the transport core, while the edge remains an IP multicasting network. In this paper, we will introduce the network architecture and discuss challenges in such IP over optical multicasting for video delivery.

In this paper, a shared sub-path protection mechanism for multi-domain opticalnetworks is proposed. It divides the computed working path into several working sub-paths which span two domains. For each working sub-path, two intra-domain and an inter-domain backup sub-paths are computed to protect intra-domain and inter-domain failures. Simulation results show it has shorter failure recovery time and is resource efficient.

In this paper security of the quantum key distribution scheme using correlations of continuous variable Einstein- Podolsky-Rosen （EPR） pairs is investigated. A new approach for calculating the secret information rate △I is proposed by using the Shannon information theory. Employing an available parameter F which is associated with the entanglement of the EPR pairs, one can detect easily the eavesdropping. Results show that the proposed scheme is secure against individual bearn splitter attack strategy with a proper squeeze parameter.
We propose a photonic crystal slab with an inflection point on the dispersion curve corresponding to a slow-light mode with reduced distortion, the transversely confined field and high quality factor of which are demo...
