    • A method of implementing a multicast routing protocol in routers is provided to manage the assignment of multicast transport addresses and to forward data from a single transmitting endpoint to multiple receiving endpoints. This method in conjunction with a method for implementing the multicast routing protocol as a transport protocol layer service for endpoints provides an internet wide multicast transport service. The multicast transport service provides the capability of transmitting data from a single source to multiple receivers on interconnected networks efficiently and without having to send duplicate copies of the data on any single network. Routers and endpoints transmit and receive multicast packets in a manner which is independent of the network layer datagram protocols used by the multicast transport service. Multicast control packets are exchanged using a multicast transaction protocol which allows routers and endpoints to execute transactions in a manner that does not require either routers to know the state of specific endpoints or endpoints to know the state of specific routers.
    • 提供了一种在路由器中实现多播路由协议的方法,用于管理组播传输地址的分配,并将数据从单个发送端点转发到多个接收端点。 该方法结合用于实现作为端点的传输协议层服务的多播路由协议的方法提供了一种互联网广播组播传输服务。 多播传输服务提供了将数据从单个源传输到互连网络上的多个接收器的能力,而无需在任何单个网络上发送数据的重复副本。 路由器和端点以独立于组播传输服务使用的网络层数据报协议的方式发送和接收组播数据包。 组播控制分组使用多播交易协议进行交换,该协议允许路由器和端点以不要求路由器知道特定端点或端点的状态以知道特定路由器的状态的方式执行事务。

    • A software-driven method for the initialization of re-writable optical media is provided. Embodiments include a software-driven method for the formatting of re-writable optical media to include defining a file system and writing a UDF reader to the optical media to enable implementation on a plurality of optical media devices in a plurality of operating system environments. The re-writable optical media is initialized using either user data or initialization patterns in a background operation to allow user interaction with the optical media during initialization. Methods are provided for multi-track capabilities of the optical media. Prior to initialization of the entire media space of an optical media, a session can be closed to enable compatibility of a partially initialized media in a ROM device. Further methods are provided to re-open a closed session to complete initialization of the media space.
    • 提供了一种用于初始化可重写光学介质的软件驱动方法。 实施例包括用于格式化可重写光学介质的软件驱动方法,以包括定义文件系统并将UDF读取器写入光学介质以使得能够在多个操作系统环境中的多个光学介质设备上实现。 可重写光学介质在背景操作中使用用户数据或初始化模式进行初始化,以允许用户在初始化期间与光学介质进行交互。 提供了用于光学介质的多轨能力的方法。 在光学介质的整个媒体空间的初始化之前,可以关闭会话以实现ROM设备中部分初始化的媒体的兼容性。 提供了进一步的方法来重新打开封闭的会话以完成媒体空间的初始化。
