OSGi(Open Service Gateway Initiative)协议

The OSGi Service Platform supports network delivered services for a remote device that can then run locally or in conjunction with other network resources. The specification is explicitly designed to be open and synergistic with a wide range of existing networking and computer technologies and enhances virtually all current networking standards and initiatives. In the same way, the specification adds value to existing wireline and wireless networks while being neutral to and complementing cable, 3G, 802.11, xDSL and other high-speed access technologies. It allows service providers to deliver value-added services of their own and selectively allow delivery of services provided by third party providers. The OSGi compliance program establishes a common specification third parties can use to create value-added services that can be delivered over a variety of networking systems using platforms incorporating compliant OSGi service platforms.





OSGi(Open Service Gateway Initiative)是一个非盈利的协会， 是由Ericsson、ABB、Alcatel、Cisco、IBM、Nortel、Oracle、Philips、Sun、Motorola、 Lucent等电信、计算机、电器巨人发起建立的一个工作组和开放式的论坛。其主要的功能是，为连接Internet上的商业服务和下一代智能电器定义一个开放的标准。因此OSGi 将成为智能信息家电平台服务标准。OSGi规范将为Internet服务提供商(ISP)、网络控制员、设备制造商提供通过运行在家中或远程地点的网关服务器传递各种电子商务服务的公共平台。OSGi在2000年发布了它的服务网关规范1.0，在2001年发布了2.0版本
OSGi规范的三个主要方面是：多种服务、广域网络、以及局域网络和设备。与其他规范不同的是，OSGi侧重于于从远程服务提供商到本地设备之间端到端的完全解决方案。由于OSGi规范专注于提供一个开放的应用层和网关接口，因此它实现和虚拟加强了当前所有的局域网络标准和规范。OSGi规范的核心部分就是作为许多通讯服务的平台的服务网关。

Oscar is an open source implementation of the Open Services Gateway Initiative (OSGi) framework specification; the goal is to to provide a completely compliant implementation of the OSGi framework specification. Oscar is currently compliant with a large portion of the OSGi 3 specifications, although certain compliance work still needs to be completed. Despite this fact, the OSGi framework functionality provided by Oscar is very stable and is in use by many people.
