    • A system for automatic program generation which receives a number of input format descriptors and a number of output format descriptors. The system generates a program for converting an input data sequence having a format described by input format descriptors to an output data sequence having a format described by the output format descriptors. The program may then be executed responsive to an input data stream, wherein a portion of the input data stream corresponds to the input data sequence. The input data sequence and output data sequence consist of a number of data type indicators. In an exemplary embodiment, the input data type indicators correspond to fields of data units received by a forwarding device, and the output data type indicators correspond to fields of corresponding data units forwarded by the forwarding device. In the exemplary embodiment, the generated program is executed on a hardware processor to convert a data unit received on a communication link over a information flow to an output data unit for transmission on a second communication link. The initial data unit of the information flow triggers generation and loading of the program while the forwarding device is up and running.
    • 一种用于自动程序生成的系统,其接收多个输入格式描述符和多个输出格式描述符。 该系统生成用于将具有由输入格式描述符描述的格式的输入数据序列转换为具有由输出格式描述符描述的格式的输出数据序列的程序。 然后可以响应于输入数据流执行程序,其中输入数据流的一部分对应于输入数据序列。 输入数据序列和输出数据序列由多个数据类型指示器组成。 在示例性实施例中,输入数据类型指示符对应于由转发设备接收的数据单元的字段,并且输出数据类型指示符对应于由转发设备转发的相应数据单元的字段。 在示例性实施例中,所生成的程序在硬件处理器上执行,以将在通信链路上接收的数据单元通过信息流转换为输出数据单元,以在第二通信链路上传输。 当转发设备启动并运行时,信息流的初始数据单元触发程序的生成和加载。

    • The present invention is an address mapping gateway, used in an internetwork link, that associates all nodes in a domain with a single network number (referred to as a domain network address), and provides gateway-mapped node addresses that are unique within the domain. The address mapping gateway dynamically substitutes the "globally-unique" domain network address and the "domain-unique" gateway-mapped node address for a network number and node address, respectively, of a network layer address of a packet header received from a source node in the domain. Conversely, when a packet is received for a destination node in the domain, the address mapping gateway substitutes the originally-assigned network number and node address for the domain network address and gateway-mapped node address, respectively, prior to forwarding the packet to the node. Specifically, the address mapping gateway maintains an address mapping table that provides a cross-reference between (1) a source node address and the network number of the local network in which the node resides, and (2) a gateway-mapped node address generated by the address mapping gateway. Upon receipt of a packet from the source node, the address mapping gateway creates a mapping entry in the address mapping table that node and performs an address translation to a globally-unique network layer address. On the other hand, upon receipt of a packet destined for a destination node in the domain, the address mapping gateway locates the mapping entry for the packet's gateway-mapped node address and performs a reverse address translation to the originally-assigned network layer address.
    • 本发明是在互联网络链路中使用的地址映射网关,其将域中的所有节点与单个网络号码(称为域网络地址)相关联,并且提供在域内是唯一的网关映射节点地址 。 地址映射网关分别动态地将“全局唯一”域网络地址和“域唯一”网关映射节点地址替换为从源接收的分组报头的网络层地址的网络号和节点地址 节点在域中。 相反,当为域中的目的地节点接收到分组时,地址映射网关将分组的原始分配的网络号和节点地址分别替换为域网络地址和网关映射节点地址,然后将分组转发到 节点。 具体地说,地址映射网关维护地址映射表,其提供(1)源节点地址与节点驻留的本地网络的网络号之间的交叉引用,以及(2)生成的网关映射节点地址 由地址映射网关。 在从源节点接收到分组时,地址映射网关在地址映射表中创建一个映射条目,该节点并执行地址转换为全局唯一的网络层地址。 另一方面,地址映射网关在接收到目的地为目的地节点的分组时,定位分组的网关映射节点地址的映射条目,并对原始分配的网络层地址进行反向地址转换。

    • Control apparatus for a nozzle for a rocket or other vehicle having a combustion chamber with a propellant therein in communication with the nozzle, the nozzle having a throat and a pair of bores extending into the throat The bores may be in opposed or any other suitable relation. A pair of plungers are slidably mounted in the bores and are movable between an open position wherein they are disposed outside of the throat and a closed position wherein they extend into the throat to substantially close it. The plungers have a width or diameter substantially the same as the width or diameter of the throat. Actuator devices are provided for moving the plungers independently of each other to control thrust by controlling the flow of combustion gases through the throat and the pressure in the combustion chamber. The movement of the plungers can also be used for thrust vector control.
