摘要： In a network management system, a method and apparatus for preparing a computer program for execution in relation to a particular network device among a plurality of network devices having a plurality of device types is provided. Each network device is associated with a device type value, and each network device has an associated device mapper. The device mappers are stored in a hierarchical structure that reflects a functional relationship or family relationship of the devices. Functions to be carried out by one or more devices are expressed as a plurality of executable program components. Preferably, each executable program component has one or more classes that define executable functions. Each device mapper associates a device type value with one or more overridden classes in the executable program components and one or more overriding classes. At runtime, device type values are acquired for each device in the managed network. For each device type, one or more functions are assembled using only the executable program components associated with that device type. Based on the device mapper of that device type, classes in the executable program components are overridden and the overriding classes are substituted. As a result, at runtime the network management system integrates into itself executable program components for new devices.

摘要： A universal addressing system for use in a digital data processing system including a universal memory for storing data including instructions and at least one local system having access to the universal memory. The universal memory is organized into objects, and each item of data is associated with an object. Each object is specified by a unique identifier, and data is addressed by means of a logical address which specifies the UID of the object containing the data and the offset of the data in the object. A processor in the local system responds to instructions by providing memory operation specifiers to the universal memory. Each memory operation specifier specifies a memory operation and a logical address. The offset in the logical address may specify any bit in the object. The memory operation specifier also specifies a length in bits. The universal memory responds to the memory operation specifier by performing the operation specified by the memory operation specifier on the data item beginning at the location specified by the logical address and containing the specified number of bits.

摘要： A method and apparatus for persistently storing information objects in a secondary store is provided. Each object to be stored persistently is made a subclass of a persistent object class. The persistent object declares metadata that defines parameters of a table in the secondary store in which instances of the object are stored, and external requirements of the object. When a persistent object inherits attributes from one or more parent object classes, instances of each parent class are represented in separate tables. When a persistent object is read or written by an application program, methods in the persistent object class automatically retrieve or store information for each field of the persistent object by recursively calling a read method or a write method for each class from which the persistent object inherits, and the object's own class. The read method and write methods automatically create and submit commands to the secondary store.

摘要： A method and apparatus are provided for verifying policies that govern a policy-based system. The method and apparatus may be implemented as a policy verifier that acts upon one or more policies. Each policy comprises a condition and a consequent. The policy verifier acquires configuration information about the system under management, thereby acquiring an understanding of the system. The policy verifier determines whether all the policies are feasible for the system, and if not, reports problems or errors that cause the policies to be non-feasible. The policy verifier also verifies that a configuration required by a particular policy consequent can be actually carried out by the managed system. In one embodiment, the policy verifier operates on network management policies, of a policy-based network management system. As a result, the invention improves the accuracy and safety of policies prepared for a network that previously did not use policy-based management.

摘要： A digital computer system having a memory system organized into objects for storing data and a processor for processing data in response to instructions. An object identifier is associated with each object. The memory system responds to logical addresses for data which specify the object containing the data and the offset of the data in the object. The objects include procedure objects and data objects. The procedure objects contain procedures including the instructions. Each instruction contains an operation code which belongs to one of several sets of operation codes. All instructions in a single procedure belong to a single operation code set, and associated with each procedure is an operation code set identifier specifying the operation code set to which the instructions in the procedure belongs. Operation codes are decoded in the processor in response to both the operation code and a dialect value representing the operation code set identifier for the operation code set to which the operation code belongs. The dialect value changes only on execution of a call operation or a return operation.

摘要： A digital data processing system has a memory organized into objects containing at least operands and instructions. Each object is identified by a unique and permanent identifier code which identifies the data processing system and the object. The system uses a protection technique to prevent unauthorized access to objects by users who are identified by a subject number which identifies the user, a process of the system for executing a user's procedure, and the type of operation of the system to be performed by the user's procedure. An access control list for each object includes an access control list entry for each subject having access rights to the object and means for confirming that a particular active subject has access rights to a particular object before permitting access to the object. The system also includes stacks for containing information relating to the current state of execution of the system.

摘要： A method and apparatus for parallel processing is provided. A parallel execution object organizes and initiates execution of two or more parallel processing threads that act on members in the context of a transaction. The members comprise one or more sets of data for which parallel processing is needed, for example, sets of network device data. The threads are organized by receiving a set of execution components that have a partial order defined by preconditions and resource requirements. A partial order evaluator resolves the partial order into a final order of execution of the components. The parallel execution object, members, transaction, and partial order can be declared in the context of an application program. Optionally, the threads are organized by selecting execution components that are optimized for use with a particular current phase of execution of the application program.

摘要： A network browsing system includes a host computer coupled to a client computer by a network. A network browser process implemented on the client computer is capable of establishing a connection with the host computer and of generating a request for desired data from the host computer which is to generate desired images on the display of the client computer. A server process implemented on the host computer services the request for desired data received from the client computer by modifying the desired data into modified data such that no additional connection between the client computer and the host computer is required to receive the entirety of the modified data. The browser process of the client computer can generate the desired images from the modified data to the same extent that it could from the originally requested desired data.

摘要： A digital data processing system including a processor and memory and employing object addressing. The digital data processing system further includes a system for organizing the system's memory into objects and a system for operating the memory. The memory organization system associates each item of data stored in the memory with an object and each object with an object identifier. The memory operation system performs memory operations on items of data in response to memory operation specifiers received from the processor. The location of a data item upon which a memory operation is to be performed is specified by a logical address. Each logical address contains an object number which is temporarily associated with one object identifier and an offset specifying a location in the object identified by the object identifier currently associated with the object number. The memory operation system includes a single object table which specifies the current temporary associations between object numbers and universal addresses and an object identifier conversion system which establishes the temporary associations in the object table and obtains the object identifiers associated with the object numbers. Also disclosed are object tables in digital data processing systems of the present invention involving a single memory and multiple processors and pointers and pointer to logical address conversion means in digital data processing systems of the present invention.
