Papers may present theories, techniques, applications, or practical experiences on topics including but not limited to the following tracks:Topics of InterestMedia streaming and real-time delivery1) Techniques and architectures for streaming media and IP telephony2) Joint source and channel coding and error control schemes3) Scalability and transcoding technologies for heterogeneous networks4) Multimedia delivery to wireless embedded devices5) Cross protocol layer design and optimizationssteadily permeated into the more focused metro/regional and edge domains. A very notable and complementary development herein has also been the rapid maturation of much-improved electronic SONET/SDH grooming technologies, broadly termed as “next-generation” SONET/SDH. As these paradigm shifts take hold, related standards activities to develop unified provisioning and control-plane architectures for optical and electronic layers have seen much impetus, particularly within the IETF and ITU-T organizations. Today, one of the major bandwidth “bottlenecks” lies in the access domain, where cumbersome legacy copper/coax infrastructures pose notable scalability hurdles toward true ultra-broadband capabilities. For many years, optical technologies were considered as too expensive and non-viable for the local loop, particularly when compared to incremental upgrades of existing legacy copper/coax plants and emerging radio wireless technologies. However, given the rapid decline in optical component price-points in recent years, advanced passive optical network (PON) access architectures have also evolved, pushing genuine fiber access all the way to the ultimate end-users. In fact, many carriers worldwide are conducting lengthy PON trials and some are even starting to offer selectedultra-broadband services to high-end users. Others are even contemplating hybrid radio/fiber access solutions to achieve a broad coverage footprint. Broadly, these trends will gain momentum over the coming years and will inevitably help usher in a new era of services, e.g., grid computing, storage extension, etc.This symposium seeks to showcase the latest developments in key open areas of optical networks and systems, and emergent service paradigms. In particular, one of the major themes will be on vertical and horizontal integration. For example, the former entails issues such as Ethernet-optical internetworking, SONET/SDH-WDMmulti-granularity grooming, traffic engineering, physical-layer aware networking, application-layer optimization, etc. Meanwhile, the latter covers topics such as multi-domain interworking and grooming, hybrid wireless-optical interworking, etc. Another major theme will be high-speed transmission and switching systems. The symposium will consist of peer-reviewed research papers as well as informative tutorials and workshop offerings from leading luminaries in the field. Moreover, broad-based participation is envisioned from academia, governmental institutions, and industry—both service providers and equipment vendors alike. Some of the key focus areas include (but are not necessarily limited to) the following:Topics of Interest1) Wavelength division multiplexing (WDM) systems2) Optical code division multiplexing (OCDM) systems3) Optical time division multiplexing (OTDM) systems4) Hybrid time and wavelength multiplexing5) Modulation and coding6) Multiple access7) Optical transmission systems8) Equipment architecture and performance9) System modeling and performance evaluation10) Demonstrators and experimental trials of optical transmission and switching systems11) Next generation SONET/SDH transmission and switching systems12) Optical cross-connect systems13) Optical packet and burst switching systems14) Optical access systems15) Hybrid wireless-optical transmission and switching systems16) Emerging standards and proposals17) Routing and wavelength assignment18) Dynamic ligthpath re-routing19) Extension of the GMPLS control plane to multi-domain20) Traffic grooming and traffic engineering21) Free space optical networks22) Multicasting in optical networks23) Optical Packet Switching (OPS)24) Optical Burst Switching (OBS)25) Single layer and multi-layer protection and restoration26) Optical switch architectures and performance27) Optical access network architectures: PON, APON, BPON, GPON, EPON, WDM-PON28) Optical network experiments: demonstrations, test beds and field trials29) Signaling and monitoring in optical networks30) Impact of the physical-layer impairments on optical network design and traffic engineering31) Horizontal integration: multi-area optical communications, Path Computing Element32) Vertical integration: multi-granularity switching33) Hybrid wireless-optical metro/access networks34) Traffic engineering for next-generation SONET/SDH35) Optical Ethernet and new service paradigms36) Optical virtual private networks37) Innovative services: grid computing, storage area networking, utility computing38) Standardization issues %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%7 SIGNAL PROCESSING AND CODING FOR DATA STORAGE (数据存储中的信号处理和编码)Signal processing and coding have been key component of data storage systems in the past (tape recording, disk drives, CD and DVD players). Recording devices simply do not work without signal processing and coding electronics. Codes and signal processing methods in data storage are unique in the sense that they need to be tailor-made to address issues in data storage: head-disk interfaces, media noise, recording physics, etc. Over the past 5 years, there has been a major shift in signal processing methods for data storage, triggered by two events:1) The shift to perpendicular magnetic recording technology, and2) The penetration of magnetic data storage into consumer electronics (MP3 players,digital cameras, video recorders, etc.)As a result, established companies that had not been in the data storage industry in the past and start-up companies are entering this exciting technical area. The symposium will present a chance for researchers in this community to present the novel approaches for signal processing and coding for data storage.Topics of Interest1) Channel characterization, including modeling of media noise and nonlinearity.2) Detection methods, including sequence detection, partial response and decision feedback.3) Modulation and run-length limited codes.4) Error-correcting codes, trellis coding and turbo codes.5) Combined equalization and coding.6) Equalization and filtering, including nonlinear techniques.7) Write precompensation and write equalization.8) Circuit designs for read/write channel electronics and coding / detection algorithms.9) Timing and gain recovery.10) New concepts for perpendicular recording.11) Noise modeling and analysis for perpendicular recording.12) Coding bounds, density, and channel capacity.13) Data compression for digital storage, including audio and video.14) AC-bias or FM linearization techniques.15) Multiple-head systems.16) Signal processing for optical storage systems: holographic, near-field, multi-level, phase change, magneto-optic, CD, DVD.17) Cost versus performance issues surrounding design of signal processing systems for storage18) Coding techniques for disk arrays.19) Special issues surrounding signal processing and coding for removable storage devices.20) Novel servo coding and formatting.21) Servo Gray code detection and processing.22) System-on-chip (SOC) architecture and optimization.23) Iterative decoding and LDPC codes.24) Efficient error control coding/decoding and LDPC codes for 4K block sectors.25) Measurement, testing, and performance optimization. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%8 SIGNAL PROCESSING FOR COMMUNICATIONS (通信中的信号处理)Topics of Interest1) Adaptive Antennas2) Adaptive Equalization3) Channel Estimation and Modeling4) Communications Electronics5) Interference Mitigation and Signal Separation6) Multiuser Systems7) Multiuser Detection8) MIMO Systems9) Modulation Techniques10) Receiver Techniques11) Signal Processing in Communications12) Signal Processing for Networks13) Source Coding and Joint Source-Channel Coding14) Space-Time Processing15) Speech and Video Signal Processing16) Synchronization17) Software Defined Radio18) Signal Processing Algorithms & Techniques19) Signal Processing for UWB20) Signal Processing for Multimedia21) OFDM and Multicarrier Systems22) Image Processing for Communications23) VLSI Circuits for Communications24) Measurement, testing, and performance optimization.25) Security & Encryption for Wired/Wireless Communications and Data Storage %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%9 WIRELESS AD HOC AND SENSOR NETWORKS (无线ad hoc和传感器网络)As computing and communications are converging, wireless ad hoc and sensor networks have attracted more and more attention in recent years. These networks will revolutionize information gathering and processing in both urban environments and inhospitable terrain. A wireless ad hoc network is an autonomous system consisting of mobile hosts (serving as routers) connected by wireless links. Such networks can be quickly and widely deployed to serve a multiplicity of purposes. Example applications of wireless ad hoc and sensor networks include, among others, emergency search-and-rescue operations, decision making in the battlefield and data acquisition operations. Sensor networks have already entered many aspects of our lives. Wireless sensors can be deployed in almost any environment, especially those where conventional wired sensor systems are impossible, unavailable or inaccessible, such as in inhospitable terrains, dangerous battlefields outer space or deep oceans. As a result, the last few years have witnessed a wealth of research ideas on ad hoc and sensor networks that are moving rapidly into commercialization and standardization. Such networks can be randomly and rapidly deployed and reconfigured and easily tailored to specific applications including civilian, military, entertainment, etc. Moreover, an ad hoc architecture is highly robust to node failure and can provide a high-level of fault tolerance due to nodal redundancy and its distributed nature. Furthermore, energy efficiency can be achieved through multi-hop routing communication. Bandwidth reuse can also benefit from dividing the。
