A seamless solution transparently addresses the characteristics of nomadic systems, and enables existing network applications to run reliably in mobile environments. The solution extends the enterprise network, letting network managers provide mobile users with easy access to the same applications as stationary users without sacrificing reliability or centralized management. The solution combines advantages of existing wire-line network standards with emerging mobile standards to create a solution that works with existing network applications. A Mobility Management Server coupled to the mobile network maintains the state of each of any number of Mobile End Systems and handles the complex session management required to maintain persistent connections to the network and to other peer processes. If a Mobile End System becomes unreachable, suspends, or changes network address (e.g., due to roaming from one network interconnect to another), the Mobility Management Server maintains the connection to the associated peer task—allowing the Mobile End System to maintain a continuous connection even though it may temporarily lose contact with its network medium. In one example, Mobility Management Server communicates with Mobile End Systems using Remote Procedure Call and Internet Mobility Protocols.

The present invention permits a JavaScript-based Remote Procedure Call (RPC) to be executed from a Web page displayed in a Web browser window, without utilizing browser plug-in, Java Applet, or ActiveX technology. Traditionally, clunky downloads and Web browser plug-ins has been required to enable Web page interactivity, which greatly compromises the performance and reach of the Web page. Based purely on HTML and JavaScript, the present invention utilizes the HTML <script> element to pass data to the server and execute a remote procedure, receiving the resulting output to the same displayed Web page. The present invention can be used to build a lightweight Web page that offers real-time data and interactivity.

An agentless software data collector in a customer computer network collects metrics data from managed devices on the network to provide to a remote data center accessed via a public wide area network (WAN) interface. The software data collector collects metrics data, as well as receives real-time queries, such as from a Remote Procedure Call (RPC) initiated from a hosted web interface.

A virtual machine monitor (VMM) is included in a computer system that has a protected host operating system (HOS). A virtual machine running at least one application via a virtual operating system is connected to the VMM. Both the HOS and the VMM have separate operating contexts and disjoint address spaces, but are both co-resident at system level. A driver that is downloadable into the HOS at system level forms a total context switch between the VMM and HOS contexts. A user-level emulator accepts commands from the VMM via the system-level driver and processes these commands as remote procedure calls. The emulator is able to issue host operating system calls and thereby access the physical system devices via the host operating system. The host operating system itself thus handles execution of certain VMM instructions, such as accessing physical devices.

An adaptive timeout value setting is determined for DCE applications, wherein the timeout value setting is adapted and adjusted according to environmental factors and communication conditions between a client / server pair. The adaptive timeout value setting takes into consideration the communication time between a client and a server in each client / server pair in determining and setting a timeout value for each pair. The timeout value for a client / server pair is adjusted in a dynamic fashion so that the client is able to be more adaptive to real environment changes and so that the server's performance is not degraded due to ineffective timeouts. The system and method determines an adaptive timeout value setting in distributed computing environment (DCE) applications for a client / server pair wherein each pair has a client system and a server system. A server response time of the server system is tracked to a remote procedure call from the client system. The remote procedure call includes a binding handle, and the server response time is based on a time of the server system responding to the remote procedure. An optimal timeout value is calculated from the response time, and a timeout value of the binding handle is reset as the optimal timeout value.

Distributed computing environment (DCE) remote procedure calls (RPCs) are integrated with an advisory work load manager (WLM) to provide a way to intelligently dispatch RPC requests among the available application server processes. The routing decisions are made dynamically (for each RPC) based on interactions between the location broker and an advisory work load manager. Furthermore, when the system contains multiple coupled processors (tightly coupled within a single frame, or loosely coupled within a computing complex, a local area network (LAN) configuration, a distributed computing environment (DCE) cell, etc.), the invention extends to balance the processing of RPC requests and the associated client sessions across the coupled systems. Once a session is assigned to a given process, the invention also supports performance monitoring and reporting, dynamic system resource allocation for the RPC requests, and potentially any other benefits that may be available through the specific work load manager (WLM).

A system is described for managing interaction between an untimed HAL portion and a timed HDL portion of the testbench, wherein the timed portion is embodied on an emulator and the un-timed portion executes on a workstation. Repeatability of verification results may be achieved even though the HAL portion and the HDL portion run in parallel with each other. A communication interface is also described for synchronizing and passing data between multiple HDL threads on the emulator domain and simultaneously-running multiple HAL threads on the workstation domain. In addition, a remote procedural-call-based communication link, transparent to the user, is generated between the workstation and the emulator. A technique provides for repeatability for blocking and non-blocking procedure calls. FSMs and synchronization logic are automatically inferred to implement remote procedural calls. A subset of behavioral language is identified that combines the power of conventional modeling paradigms with RTL performance.

A computer system in accordance with the present invention provides a method of communicating events from a server to remote procedure call clients. The disclosed technique begins with a remote procedure call by a remote procedure call client to a server to establish an initial client-server connection. Next, there is a remote procedure call to create a guaranteed delivery communication conduit, such as a named pipe, between the server and client and to create a server asynchronous event thread in a blocked state for blocking execution of the server asynchronous event thread. A client asynchronous event thread in the client is then created to open the named pipe. If the server detects an event, an event message is generated which places the server asynchronous event thread in an unblocked state to allow execution of the server asynchronous event thread. Event data may then be transmitted across the named pipe from the server to the client. After transfer of the event data is complete, the server asynchronous event thread is blocked. By unblocking the server asynchronous event thread when an event is detected and blocking the server asynchronous event thread following transmission of the event through a named pipe to the client, asynchronous events may be communicated by a server to remote procedure call clients. As a result, it is not necessary for a remote procedure call client to poll a server to receive asynchronous event information.

A mechanism for access control based on remote procedure calls is established whereby server management costs for the processing associated with the authentication of client access rights and the provision of requested resources can be reduced by distributing these costs among clients. A first client, which has an access right to a server via a network, can issue a remote procedure call to the server. The first client can also communicate with a second client, which doesn't have an access right to the server. The first client requests the server to issue a token, which is a data set for permitting the second client a limited access to the server, and subsequently the token prepared by the server is transmitted to the second client. The second client originally has no access rights relative to the server. However, if the second client transmits a remote procedure call using the received token, limited access is granted. The server performs a process designated by the remote procedure call from the second client. The token includes operating information for designating an operation to be performed based on the remote procedure call, and identification information for identifying the second client.

A method for avoiding directory conflicts across a file system having multiple nodes with one node representing a token manager. For each directory, at least one metanode responsible for directory updates. The method involving obtaining a name-based lock on a filename. Querying the token manager for a lock token. If a new token is obtained, sending a Remote Procedure Call (RPC) to the metanode to obtain matching directory entries, and caching the result of the RPC so that subsequent operations on that filename can be satisfied without additional messages sent to the metanode. Updating a cached directory block in memory by creating a new directory entry in the block or deleting an existing directory entry from the block. Information regarding the updating is sent to the metanode on one of: periodic schedule, a subsequent synchronization event, or when the name-based lock token is revoked.

For each high-level protocol, a respective mesh of Transmission Control Protocol (TCP) connections is set up for a cluster of server computers for the forwarding of client requests. Each mesh has a respective pair of TCP connections in opposite directions between each pair of server computers in the cluster. The high-level protocols, for example, include the Network File System (NFS) protocol, and the Common Internet File System (CIFS) protocol. Each mesh can be shared among multiple clients because there is no need for maintenance of separate TCP connection state for each client. The server computers may use Remote Procedure Call (RPC) semantics for the forwarding of the client requests, and prior to the forwarding of a client request, a new unique transaction ID can substituted for an original transaction ID in the client request so that forwarded requests have unique transaction IDs.
