摘要： A data transmission network having a port-based default VLAN that limits flooding to other VLANs. The default VLAN receives a data packet, ascertains the destination address of the packet, and then determines if the destination port is one of the default VLAN ports. The data packet is transmitted to the destination port if it is one of the default VLAN ports, or to each of the default VLAN ports if the destination port is not one of the default VLAN ports. The data packet is not transmitted to any other non-default VLAN port.

摘要： Method and apparatus for coordinating access to a shared object amongst a plurality of processes in a distributed system. One process is identified as a lock owner process controlling a lock associated with the shared object. When a process needs to access the shared object, it requests control of the lock from the lock owner process. When no other process controls the lock, the lock owner process grants control to the requesting process. When another process controls the lock, the lock owner process places the requesting process in a queue and waits for the lock to become available. All accesses to the shared object are processed through the lock owner processes thus assuring coordination and synchronization among the processes.

摘要： A network is monitored for reports indicative of a connection state among ports of a communications network. Certain ports are designated as being in a transition, and a transition table is created for each transition. The transition table includes locations that directly relate the connectivity of a first port with respect to a second port, as well as locations that relate the connectivity of other ports. The contents of the transition table are evaluated to determine the likely configuration of the communications network. State machines may be used to resolve conflicting data within the transition table, by providing a likely connection output based upon different entries within the transition table. A voting scheme is used to evaluate the outputs of the state machines and update the transition table when appropriate, and the updated transition table may also be evaluated.

摘要： Method and apparatus providing connection-oriented services for packet switched data communications networks. Directory services include distributed discovery of MAC addresses and protocol alias addresses. Topology services include a link state topology exchange among switches, which provides each switch with a complete topology graph of the network. This enables an access switch receiving a data packet to determine a complete path from a source end system to a destination end system. Another service includes resolution of broadcast frames to unicast frames, in order to reduce the amount of broadcast traffic. Policy restrictions may be applied prior to connection setup. Path determination services enable multiple paths from a source to a destination. Connection management includes source routed mapping of connections on the desired path. A distributed call rerouting service is provided wherein if a link on an active path fails, each switch receives a topology change notification and unmaps any connection involving the failed link. A broadcast/unknown service provides restricted flooding of nonresolvable packets. Furthermore, connection-oriented switching is provided based on the source and destination MAC addresses as a connection identifier. Still further, resolution of networks outside the switch domain is enabled by access switches listening for network and server route advertisements and maintaining best routes to said netowrks and servers. The best route metrics may be combined with best path metrics to determine a path from a first access switch to an egress switch connected to the external network.

摘要： Apparatus and method for learning current network behavior and predicting future behavior which utilizes a state transition graph (40). The graph includes nodes (41-46) which represent network states, and arcs (48) which represent trends in observable network parameters that result in a transition from a current state to another state. For example, a watch service may be instituted on multiple ports of a router (3, 4), and the observed network traffic on the ports over time may be transformed into a state transition graph that represents network behavior. The network states may be labeled such as "good", or "bad", etc., according to a predetermined performance criteria. Once a state transition graph is constructed, the system may then monitor the current state and current trends of the network parameters in order to predict and display future network states. The system may include an automatic warning signal for alerting a user that the network is headed in the direction of a problematic state.

A defuzzifier module (46) is coupled to the fuzzy inference engine (28) and converts the fuzzy output data into numeric data which may be then used by a network controller to control at least one network parameter in response to the output data. The apparatus may also include a user interface (34) and a display (44) to allow the fuzzy input data, and the fuzzy output data to be displayed to a user. Using the user inferface (34), the user can then modify the fuzzy input data, the fuzzy output data, and the fuzzy rules. A method for monitoring and controlling communications networks is also disclosed. A methodology for designing membership functions and fuzzy rules useful for monitoring and control of communications networks is disclosed. The system provides for reporting of network behavior in common sense terms, providing recommendations to a user regarding network operational parameters, and, in one embodiment, complete automatic monitoring and control network operational parameters.

摘要： The operating mode of a memory controller for a random access memory having multiplexed address lines is selected to provide the highest operating speed for the addresses being presented to the memory. Each address supplied to the memory includes a row address and a column address. A page fault detector detects a page fault when the row address changes on successive transfers to the memory and detects a non-page fault when the row address remains the same on successive transfers to the memory. The operating mode is automatically selected in response to the difference between the number of page faults and the number of non-page faults to provide the highest operating speed. When the difference between the number of page faults and the number of non-page faults is equal to or greater than an upper threshold value, the memory mode is set to non-page mode. When the difference between the number of page faults and the number of non-page faults is equal to or less than a lower threshold value, the memory mode is set to page mode.

摘要： A network management system includes a user interface (10), a virtual network (12) and a device communication manager (14). The virtual network (12) includes models (130-135) which represent network entities (30-35) and model relations which represent relations between network entities. Each model (130-135) includes network data relating to a corresponding network entity (30-35) and one or more inference handlers for processing the network data to provide user information. The system can poll or communicate with certain network entities (510, 520, 530, 540, 550) and can infer the status of network connector and other entities (500) for which polling is impossible or impractical. The system performs a fault isolation technique wherein the fault status of the network device is suppressed when it is determined that the device is not defective. User displays include hierarchical location views and topological views of the network configuration. Network devices are represented on the displays by multifunction icons (330, 332, 334) which permit the user to select additional displays showing detailed information regarding different aspects of the corresponding network device.
