Abstract: A method of dynamically configuring and monitoring every host connected to a gateway device, where at least one initiating host and one receiving host is at least connected to the gateway device in a computing network environment. All information about all connected hosts and their addresses are first determined and stored in a port-sharing table in a memory location accessible to the gateway device. The availability of each host connection is monitored and checked at preselected intervals and if any host becomes unavailable, a change in status is made in the portsharing table. When a special IP address command is issued for a particular initiating host, such as a SET IP address command, all IP datagrams for that particular host is received and in turn compared to the entries in the portsharing table.

Abstract: A method of allowing any initiating host to establish communications with any receiving host in a computing network using a Multi-path channel communication protocol. The computing environment also having a gateway device that is electronically connected from one end to at least one initiating host and at the other end to at least one local area network through which a plurality of hosts are connected to the gateway device. During an initialization step all functions commercially available on all communication platforms are inputted in a special function table. Then the particular associated platform is queried and the functions provided in the computing environment is determined and inputted also in the function table. All alterations and modifications to the availability of old functions or addition of new functions are also monitored and inputted in the table.

Abstract: An option request protocol allows dynamic negotiation of options between a host computer and a control unit of a computer network. The protocol is manifested as an exchange of novel control messages over a control link used to establish logical data links for communication between the host and control unit. The options negotiated by the control message exchange generally pertain to additional functions performed by the control unit or host, or additional parameters for communication over the data links coupling the control unit and host.

Abstract: When data is to be sent from a communication apparatus connected to a local area network (LAN) to a destination communication apparatus via a communication line, communication parameters related to the destination communication apparatus are inquired to a predetermined terminal apparatus upon reception of a transmission request from a terminal apparatus connected to the LAN. Communication control of the data is performed in accordance with the transmission request based on the communication parameters obtained by the inquiry. Also transmission control of the data is performed in accordance with a communication mode decided based upon the result of an interpretation of reception capability of the destination communication apparatus.

Abstract: A data processing system having a client system, a server system for connection to the client system, and a remote user terminal for connection to the server system. The client stores application code which is executed on receipt of a remote access request to generate output requests which are communicated to the server. The terminal issues the remote access request to the server. The output requests are display requests directed to manipulating the display screen, and non-display requests which can be processed independently of the terminal. The server forwards the remote access request to the client, stores decoding code, sends the decoding code to the terminal on detection of the remote access request, receives the output requests from the client, generates responses to the non-display requests on behalf of the terminal, returns the responses generated to the client and forwards the display requests to the terminal.

Abstract: Various operational measurements of a network element are determined in real time. These measurements are used to determine the call carrying capacity of the elements and the reaction of the network element to various call loads. Models of the network elements are generated from the operational measurements. Using an element's model, the network's reaction to various changes in a particular element can be determined without complex and expensive engineering work.

Abstract: This invention relates to a method and protocol to enable a simple, reliable and highly scaleable data transfer facility in a digital data network. A connectionless, unacknowledged data transfer protocol minimizes resource utilization at a data server and is combined with source rate control to reduce congestion in the intervening network. The data transfer server implementing the protocol, operates by defining a circular ordering of individual scheduling timeslots having zero or more download records. The server selects in sequence, at a predetermined rate, the individual scheduling timeslots, and services, responsive to the selected timeslot having at least one download record, each record therein according to parameters in that record.
