摘要： A network input/output processing system for sending and receiving messages between a large scale computer system and associated communications networks. Executive operating system services provide access to a control table, an input queue, and an output queue stored in the computer system's main memory. A network input/output processor responds to requests by application programs, through a communications program, for receiving input from and sending output to a network, concurrently with requests to communicate with directly attached peripheral devices such as disk drives, tape drives, and printers. The network input/output processor receives initialization, reset, and termination requests via the control table. Requests to receive input are received from the input queue. Input data is stored into buffers as directed by the input request. Requests to send output are received from the output queue. Output data is read from the buffers as directed by the output request. Executive operating system services provide for control of input data transfers and output data transfers. Special purpose Instruction Processor instructions provide the capability to build control programs for processing input and output messages used by the network input/output processor to effect message transfers, thereby minimizing host instruction pathlength for communications I/O. The system architecture minimizes internal data copy between processes by using transferable buffers as communications buffers.

摘要： A system and method for interprocess communication between concurrently executing, cooperating sequential processes in a digital computer system uses a shared memory queue as a mechanism for message passing and process synchronization. Data to be transferred from a sending process to a receiving process is stored in a queue entry which is visible in the virtual address space of the first process. The queue entry is added to a queue by the sending process directing the processor to execute an enqueue instruction. The receiving process removes the queue entry from the queue by directing the processor to execute a dequeue instruction. The receiving process then has direct access and visibility to the contents of the queue entry without having to copy the data into its virtual address space. Instead of sending data in a queue entry, a sending process may send an event indicator and no data. The receiving process may then wait on an empty queue until an event notification is received in a queue entry enqueued to the queue. Protection is provided by the system to prevent unauthorized access to the queue by other processes active in the system.

摘要： A system and method for interprocess communication between concurrently executing, cooperating sequential processes in a digital computer system uses a shared memory queue as a mechanism for message passing and process synchronization. Data to be transferred from a sending process to a receiving process is stored in a queue entry on the shared memory queue. Hierarchical queuing allows a sending process to collect multiple message segments as entries in a local sub-queue, which is enqueued as a single entity to the shared memory queue when all message segments are present. The receiving process dequeues the sub-queue in one operation, thereby increasing the efficiency of message transfer while preventing the erroneous dequeuing of message segments when multiple receiving processes are waiting on the same shared memory queue. In this manner, the logical maximum size of a message being passed between processes is expanded.

摘要： A system and method for adding a queue entry containing message data to a queue shared by communicating, sequential processes includes an enqueue instruction. The enqueue instruction attaches a queue entry to either the tail or the head of the shared queue, as specified by an application programmer. Execution of the enqueue instruction includes blocking access to the queue by other processes, updating queue linkages, activating processes waiting on entries being made to the queue, monitoring interrupts, and validating the appropriate queue data structures. If desired, in lieu of adding a queue entry containing message data to the queue, the enqueue instruction inserts an event indicator into the shared queue structure, thereby providing synchronization capabilities between communicating processes.

摘要： A system and method for removing a queue entry containing message data from a queue shared by communicating, sequential processes includes dequeue (DEQ) and dequeue or wait (DEQW) instructions. The dequeue instruction removes a queue entry from the head of the shared queue, thereby providing access to the message data contained in the queue entry to the dequeuing process. The dequeue or wait instruction removes a queue entry from the shared queue if there is one, otherwise it suspends the execution of the dequeuing process until an entry is enqueued to the queue. If an event is selected by the dequeuing process, the dequeuing process is suspended until notification of the event is detected in the shared queue. Execution of the dequeue and dequeue or wait instructions include blocking access to the queue by other processes, updating queue linkages, deactivating processes waiting on entries or events being made to the queue, monitoring interrupts, and validating the appropriate queue data structures.

摘要： A method of and apparatus for efficiently providing video on demand services to a cable television subscriber. The provider system consists of two major subsystems. The first subsystem, called a video server, streams video to video on demand subscribers through the cable television network. The second subsystem, called the transaction server, performs virtually all remaining provider functions including, security, accounting, storage and spooling of video data, etc. The transaction server preferably uses a large scale mainframe computer. The video server subsystem may be a partitioned portion of same large scale mainframe computer.

摘要： An Internet checksum for use by TCP/IP is generated in a single macro-instruction called a Block Add Octets instruction. Extraneous overhead of macro-instruction looping and bit masking is eliminated by combining checksum operations into a single macro-instruction using a block add approach. The programmer specifies the address in memory and the number of double-words of message data to be added together within a single instance of the Block Add Octets instruction so that looping and jump/branch instructions are not needed. The Block Add Octets instruction fetches all octets (8-bit data segments) contained in full double words from memory and adds them into the checksum. The method handles partial double words of data, full double words, and odd numbers of double words, whereby a double word consists of four octets. The checksum is calculated using one's complement arithmetic rather than two's complement, thereby increasing the speed of checksum calculation because the "end around carry" is eliminated. The number of octets that can be added to the checksum per processor cycle is greatly increased, thereby significantly improving overall TCP/IP performance.
摘要翻译：在一个名为Block Add Octets指令的宏指令中生成TCP / IP使用的Internet校验和。通过使用块添加方法将校验和操作组合到单个宏指令中，消除了宏指令循环和位掩码的外部开销。程序员在Block Add Octets指令的单个实例中指定内存中的地址和要添加在一起的消息数据的双字数，以便不需要循环和跳转/分支指令。块添加八位字节指令从内存中获取包含在全双字中的所有八位字节（8位数据段），并将它们添加到校验和中。该方法处理部分双字数据，全双字和奇数双字，由此双字由四个字节组成。使用补码算术而不是二进制补码来计算校验和，从而增加校验和计算的速度，因为“结束执行”被消除。每个处理器周期可以添加到校验和的八位字节数量大大增加，从而显着提高整体TCP / IP性能。

摘要： An apparatus for providing a computing environment in a computing system includes a first node, a second node, an operations server, and a communication link. The first node is capable of supporting a production computing environment and has a first disk storage. The second node is capable of supporting a second operational computing environment, independent of the production computing environment and has a second disk storage. The operations server manages the first and second node and can switch the production computing environment from the first node to the second node. The communications link allows communication between the first node, the second node, and the operations server. The second node can take over the production computing environment from the first node upon a failure of the first node by providing the second node with access to the first disk storage and rebooting the second node from the first disk storage. A method of switching a production computing environment from a first node, having a first disk storage, to a second node in the event of a failure on the first node includes determining if the first node had a failure and if the first node had a failure: reassigning ownership of the partition definition to the second node; restoring communications configuration on the second node; and booting the second node from the first disk storage.
