TL;DR: In this article, a broker allocates a plurality of servers, each having an available resource capacity, to clients for delivering one of several services to the clients by monitoring a subset of all available servers capable of delivering the requested service.
Abstract: In a computer network, a broker mechanism allocates a plurality of servers, each having an available resource capacity, to a plurality of clients for delivering one of several services to the clients. The broker operates by monitoring a subset of all available servers capable of delivering the requested service. The allocation is based on developing a network policy for the plurality of servers by collecting a local policy for each of the servers. The broker receives client requests for the services and based on the network policy and available resource capacity suggests one of the servers, monitors in its subset for that particular service, to one of the clients making a request. The server suggested enforces its local policy by not allowing any connections exceeding its available resource capacity.

28 Sep 1987TL;DR: In this paper, a file and resource serving and locking service is provided by a user level request server on the intermediate computer to make requested files or resources available on or through the intermediate computers to the operating system.
Abstract: A computer network (FIG. 1) comprises a plurality of personal computers (PCs 10), groups of which are each logically connected to a different one of a plurality of intermediate computers (11). At least one of the intermediate computers is connected to a mainframe computer (12). File and resource serving and locking services are provided transparently to PC user programs (200). Certain user service requests ("open file" and "exit" calls) on each PC to the PC operating systems means (20,22) are trapped by an operating system kernel-level patch (21), and corresponding requests are sent to a kernel-level driver (31) on the associated intermediate computer. The driver collects requests from all PCs associated with the intermediate computer and funnels them to a user level request server (32) on the intermediate computer. The request server performs requested file and resource serving and locking services in an effort to make requested files or resources available on or through the intermediate computer to the PC's operating system. The request server calls upon a NETSVR process (33) to find requested files and resources on other intermediate computers and to transfer requested files to its intermediate computer. The request server calls upon an APISVR process (34) to obtain requested files unavilable on intermediate computers (11) from a database (13) of the mainframe computer. The request server returns notices of its successor failure to the patch through the driver. In response to the notices, the patch forwards the trapped user requests to the PC operating system to service the requests. The PC operating system views and uses the associated intermediate computer as a peripheral device to satsify user file or resource requests.

TL;DR: The system for organizing communication among applications in a data processing network includes data bases and data base control means as discussed by the authors, which include method entries, message entries, and class entries, each of which contains information about classes consisting of instances which have common characteristics.
Abstract: The system for organizing communication among applications in a data processing network includes data bases and data base control means. The data bases include method entries, message entries, and class entries. Method entries refer to commands or other mechanisms used to invoke applications. Message entries each represent a type of operation which can be performed on instances in a class which correspond to that message and identify a method map which contains one or more references to method entries stored in the data base. Class entries, each of which is unique in a data base, contain information about classes consisting of instances which have common characteristics as well as identifying a corresponding group of message entries. The data base control means includes an invoker for identifying a method entry corresponding to the instance identifier and type of operation identified in a request for remote invocation of an application, and a dispatcher for transmitting the command identified in the method entry to the remote application. The system may include data bases in a data processing network comprised of one or more platforms or nodes and may be either global data bases accessible to the entire network or local data bases, each of which is accessible to only a part of the network.

TL;DR: In this paper, a method for executing an application on a compute server of a computer network or other computer system that includes the compute server and at least one client system is described.
Abstract: A method is provided for executing an application on a compute server of a computer network or other computer system that includes the compute server and at least one client system. The client system makes a remote procedure call to the compute server, and the remote procedure call is transported by the computer network or computer system from the client system to the compute server. Execution of the client program that made the remote procedure call is suspended until the compute reserver returns the results of executing the remote procedure call. After the compute server begins processing the remote procedure call it may determine that additional information is needed from the client system to process the remote procedure call. In that case, the compute server initiates a remote procedure callback to the client system to request the required additional information, and that remote procedure callback is transported back to the client system by the computer network. The client system receives and processes the remote procedure callback and returns the requested additional information to the compute server. The compute server can make more than one remote procedure callback to the client system. When the compute server finishes processing the client system's remote procedure call, the results generated by the compute server are sent back to the client system.
