Operating System and Middleware Support for Multi-Media Systems Area Network

提案编号：CCR-9972243标题：多媒体系统区域网络的操作系统和中间件支持PI：Kamlesh Rath多媒体设备正在围绕新的串行系统区域网络（SSAN）标准发展，例如FireWire（IEEE 1394）和SerialExpress（IEEE P3100）。与当前的系统总线和局域网技术相比，这些技术以非常低的成本提供了网络多媒体设备所需的带宽。高带宽SSAN上的多媒体设备的操作系统增强功能可以在设备之间共享处理、存储和外围设备资源。SSAN上的设备中的操作系统和中间件软件需要执行以下功能：（i）管理网络和外围接口硬件，（ii）为热插拔设备提供基于动态事务的设备注册和资源管理机制，（iii）提供基于应用和多媒体数据/流需求的自动缓冲区管理，（iv）提供用于实时数据的单拷贝用户到网络接口的数据传输机制，（v）提供用于在客户端上集成呈现相关媒体流的机制。设计和开发多媒体设备的动态资源管理软件和SSANs的传输层软件。操作系统增强和中间件正在轻量级实时内核上开发，使用最小的POSIX兼容子集以实现可移植性。

PROPOSAL NUMBER: CCR-9972243TITLE: Operating System and Middleware Support for a Multi-media Systems Area NetworkPI: Kamlesh RathMulti-media appliances are evolving around new serial systems areanetwork (SSAN) standards, e.g. FireWire (IEEE1394) and SerialExpress(IEEE P3100). These provide the band-width needed for networkingmulti-media appliances at a very low cost compared to current system-busand LAN technologies. Operating system enhancements for multi-mediaappliances on high-bandwidth SSANs can enable sharing of processing,storage and peripheral resources between appliances.The operating system and middleware software in appliances on a SSANare required to perform the following functions: (i) manage the networkand peripheral interface hardware, (ii) provide dynamic transactionbased device registration and resource management mechanisms forhot-pluggable devices, (iii) provide automatic buffer management basedon application and multi-media data/stream requirements, (iv) provideone-copy user to network interface data transfer mechanism for real-timedata, and (v) provide mechanisms for integrated presentation of relatedmedia streams on a client.This research focuses on analysis, design and development of dynamicresource management software for multi-media appliances and transportlayer software for SSANs. The operating system enhancements andmiddleware are being developed on a light-weight real-time kernel usinga minimal POSIX compliant sub-set for portability.
