摘要： A system for controlling the transmission of cells from a network node over multiple virtual circuit is disclosed. The disclosed system performs traffic shaping for all virtual circuits connected with the network node. The system includes a virtual circuit table with one or more entries. Each virtual circuit table entry corresponds to a virtual circuit established with the network node. Each virtual circuit table further includes one or more Cell Rate Accumulator fields and a Time Stamp field. The system includes a schedule table having one or more entries. Each schedule table entry further includes one or more Cell Rate Accumulator fields and corresponding predetermined value fields. A schedule table loading process determines a virtual circuit on which a packet is to be transmitted, and then calculates a time elapsed since a last previous write of a virtual circuit table entry corresponding with that virtual circuit. The schedule table loading process then adds the time elapsed to the value of the Cell Rate Accumulator fields in that virtual circuit table entry, and stores the result of the addition into the corresponding Cell Rate Accumulator fields of the schedule table entry. The system further includes a process for periodically incrementing the Cell Rate Accumulator fields in the schedule table entry. A scanning process periodically increments the Cell Rate Accumulator fields. A transmitting process transmits a cell on the virtual circuit when the value of the Cell Rate Accumulator fields is greater than or equal to the corresponding predetermined values.

摘要： A system for controlling the transmission of cells from a network node over multiple Virtual Circuits (VCs) is disclosed. The system performs traffic shaping, as required by connection based systems such as Asynchronous Transfer Mode (ATM), for each VC connected with a network node, so that the Quality of Service (Qos) parameters established when the connection was established are not exceeded. The system includes a process for scheduling the transmission of cells from the network node. The scheduling process periodically scans a table having entries corresponding to virtual circuits connected with the network node. During each scan of the table, the scheduler increments a sustainable rate accumulator field, a peak rate accumulator field, and a latency accumulator field of each table entry that corresponds with a virtual circuit that is open, and for which there is a cell ready to be transmitted. The scheduler further determines if the sustainable rate accumulator value is greater than or equal to a predetermined value and whether the peak rate accumulator value is greater than or equal to a predetermined value. If both conditions are true, then a cell may be transmitted on the virtual circuit corresponding with that table entry. The system further provides that transmissions are scheduled on virtual circuits having the greatest latency since previous transmissions.

摘要： An apparatus and method for transferring data in a data processing system to and from a host system. A communication adapter or input/output controller device is provided in which queues are utilized to transfer information between the adapter or controller and the host system. In order to minimize the amount of time a system or I/O bus or network is used during transfer of data between the adapter or controller and the host system, and reduce the amount of work that must be performed by the host system, the number of interrupts by the adapter or controller of the host system is limited to the minimum amount necessary by using an interrupt arm mechanism and by keeping track of completion indices stored in the host system.

摘要： A device and related method for coupling segments of an extended local area network (LAN) in such a way that message traffic employing inter-network protocols such as TCP/IP will be handled without the difficulties usually associated with bridges, and without the complexity and expense of full IP router capability. The device operates like a bridge for non-TCP/IP traffic. For TCP/IP traffic it operates in a bridge-like manner but maintains a database associating extended LAN segment addresses with port numbers in the device, so that packets can be automatically forwarded over a spanning tree connecting the network segments. A host computer in any network segment can address others in different network segments of the extended LAN as though all were in a single LAN. The device of the invention functions to block the flow of ARP messages and to generate ARP replies that render the device of the invention transparent to hosts within the extended LAN. The device is also transparent to true IP routers, which may still be used to effect communication with points outside the extended LAN.

摘要： The systems and methods described herein include methods for providing resources over a data network. The methods may be embodied as processes operating on a computer server, wherein that server comprises a plurality of server platforms, each of which are truly equivalent in that each provides a functionally equivalent interface to a client. In one practice of the invention, a method responds to client requests by detecting a request from a client for access to a resource and by establishing a connection for communicating with the client. The method then identifies a server available for servicing the detected request, and determines whether state information is associated with the connection. The method then, grants the identified server with access to the state information and allows the identified server to create and transmit a response to the client, also allowing the identified server to update the state information.

摘要： The routing paths are determined in a step-by-step nature. A Dijkstra algorithm is used and before labeling a link as a routing path, all possible routing paths which are within a predetermined range are compared. One of the paths in the range are chosen at random to be the routing path.
