摘要： The invention relates to a protocol for exchanging data between applications of a portable multi-application object, such as a microprocessor or smart card. An internal communications interface is implanted in the nonvolatile memory of the smart card. Given a message sending command and message reception command, a source application attribute (E-ID) is assigned a) to an application, and a target application attribute (R-ID) is assigned b) to at least one other application. The exchange of information messages (MSG) c) is done between source and target applications by means of the communications interface used as an intermediary. The invention is applicable to the management of portable multi-application objects, such as processor cards, PCMCIA cards, or the like.

摘要： The state of one or more server-side control objects is managed using a transportable state structure that is communicated between a web server and a client. The transportable state structure may include state information, hierarchical information, and an integrity code. The state information is related to properties of the server-side control objects. The hierarchical information is used by the server to locate an appropriate server-side control object in the hierarchy into which associated state information is to be loaded. The integrity code allows the server to determine whether the transportable state structure was corrupted during the round-trip between the server and the client. Prior to a response to the client, the state information of one or more server-side control objects is recorded into the transportable state structure for transmission to the client in the response. The transportable state structure is then returned to the server and loaded into the server-side control objects to restore the hierarchy to its previous state.

摘要： A computer network includes a client and a server which are preferably independently operable computers that cooperate to perform different procedures of an application program. The server executes its procedure in response to a remote procedure call transmitted over the computer network from the client. The remote procedure call typically includes one or more data structures or parameters used as arguments for executing the remote procedure. The server receives the remote procedure call at an RPC buffer. In accordance with the present invention, the server interprets the parameters while the remote procedure call resides in the RPC buffer whenever the selected format of the parameters of the remote procedure call matches the data structure format processed by the server.

摘要： A method of allowing a secure and transparent communication between a user device and servers of a data access network system via a firewall and a gateway is described. The method includes the step of designating a plurality of ports in the firewall for the gateway, each corresponding to one of a number of ports in the gateway. Each of the gateway ports can be dynamically assigned to correspond to the port of one of the servers. The method also includes a step of proxifying an object reference used in a user request for a target server from the user device in order to establish secure connection between the user device and the target server. This step is first performed by replacing the IP address and the port number of the target server of the user request with a dynamically assigned gateway port and the IP address of the gateway. Then the dynamically assigned gateway port and the gateway's IP address are mapped to the port of and IP address of the target server such that the user request is not required to expose the IP address and port number of the target server at the gateway.

摘要： A computer operating system that allows legacy applications to be run automatically with quality of service (QoS) guarantees matching required QoS performance levels. In accordance with the invention, files have QoS requirement attributes that can be set-by users. Additionally, users may interpose a requirement broker between a given legacy application and the operating system. The requirement broker may be in the form of a modified version of a library that is dynamically linked with applications at load time. The requirement broker intercepts certain system calls and automatically requests from the system QoS guarantees in accordance with the QoS requirement attributes of the accessed files, whether local or remote.

摘要： A client-server system includes a new front end server which interposes itself between a prior (back end) server and its clients using an interposed dynamically-loaded library linked to the back end. The interposed library and front end can provide enhanced services without requiring reconfiguration of either the back end server or its clients. The front end can accept network connections on the same port as the back end server is programmed to. The interposed library intercepts standard network system calls by the back end and emulates their behavior by communicating with the front end. The front end can send file descriptors of either direct connections with clients, or of pipes for relaying requests and response from and to clients through the front end, to the interposed library for return to calls by the back end to accept connections. The capabilities which the front end can provide include caching, protocol conversion, session affinity, filtering, traffic conversion, and spreading load between multiple back end processes.

摘要： Switch controller application programmer interfaces (SCAPIs) are described herein. The SCAPIs allow for communication with routines of an application program that resides in memory of a switch controller. The switch controller is a component within a telecommunications network that provides an interface between a public switched telephone network via programmable switches and intelligent service network components. Intelligent service network components may provide an interface to other networks and/or perform enhanced service call processing. Functions performed using SCAPI procedures include interface with the programmable switches, health monitoring, requesting processes to perform tasks, interface with intelligent service network components, and enhanced service call processing. SCAPIs are procedures that reside in memory of the switch controller and, when performed by processing computer program commands, cause SCAPI messages to be sent that provide communication with routines within the switch controller application program.

摘要： A software system is disclosed which provides for dynamic generation of remote proxy classes at run time through a distributed object management system 16. The software system provides for a client system 14 and server system 12 which communicate via distributed object management system 16 which operates over a distributed computer network to allow communications between client system 14 and server system 12. Any inter-object communication will invoke a remote proxy generation control module 34 if a remote proxy class 23 does not already exist for the requested subject object 18. A remote proxy generation control module 34 is provided which first invokes reflection engine 36 to determine the applicable information of subject class 19. Next, a communication enabling module 40 determines and inserts the appropriate computer code to allow local object 20 to communicate with subject object 18 utilizing remote proxy object 22. After the system determines what information is required by remote proxy class 23, byte code generator 42 automatically generates the executable code containing remote proxy class 23. Finally, class loader 46 loads remote proxy class 23 onto the system and creates a new instance which is remote proxy object 22.
