摘要： Embodiments provide systems, methods, and computer program products for inferring the switch port connectivity of discovered but. unmanaged devices in a network without direct access to the devices. Embodiments operate by generating a physical address-to-port map based on collected operational data and then pruning the generated map based on switch port connectivity information and/or inferred link connectivity information. The switch port connectivity of discovered unmanaged devices is then generated or updated based on the pruned map. The switch port connectivity information can be used by various other tools to enable diagramming, asset inventory, and network planning, design, and optimization workflows.

摘要： Embodiments for quick network path discovery are provided. Embodiments may be used by a user (e.g., network administrator) in troubleshooting a performance/communication problem in the network. M an embodiment, path information, including Layer-3 and/or Layer-2 path information, can be requested between any pair of devices in the network and presented to the user. In an embodiment, path information is provided to the user in an iterative (or gradual) manner as soon as resolved. This allows the user quick access to path information, which both reduces troubleshooting time and enhances the user experience. In addition, in an embodiment, the path information may be provided without any live interaction with any device in the network.

摘要： The embodiments relate to modeling wireless communications in a network. In wireless communications, the nodes share one or more wireless communication channels. When a node has data to transmit, it must contend with the other nodes for access to the wireless communication channel. In the embodiments, the model is configured to simulate the throughput effects of contention including delays caused by retransmissions due to interference and collisions, listen-and-backoff, unavailability of time slots, etc. The occurrence of failed/dropped transmissions due to buffer overflows, excessive retransmission attempts, and unintended collisions are modeled as well. In addition, the embodiments may simulate the effect of mobility by the nodes and the effect of the location of the nodes relative to each other.

摘要： Data representing application deployment attributes, network topology, and network performance attributes based on a reduced set of element attributes is utilized to simulate application deployment. The data may be received from a user directly, a program that models a network topology or application behavior, and a wizard that implies the data based on an interview process. The simulation may be based on application deployment attributes including application traffic pattern, application message sizes, network topology, and network performance attributes. The element attributes may be determined from a lookup table of element operating characteristics that may contain element maximum and minimum boundary operating values utilized to interpolate other operating conditions. Application response time may be derived using an iterative analysis based on multiple instances of one or more applications wherein a predetermined number of iterations is used or until a substantially steady state of network performance is achieved.

摘要： An access discovery method and system discovers and stores the proper access protocol for each device on a network. The discovery process includes progressively sequencing through state transitions until a successful access protocol sequence is determined, and an access script corresponding to this sequence is stored for subsequent access to the device. Preferably, the protocol-discovery algorithm is modeled as a state table that includes a start state and two possible terminal states: success and failure. A state machine executes the state table until a terminal state is reached; if the terminal state is a failure, the system backtracks to attempt an alternative sequence. The process continues until the success state is reached or until all possible sequences are executed without success. An exemplary state model is provided that has been shown to be effective for modeling network devices from a variety of vendor devices.

摘要： The connectivity information provided by a variety of inference engines is integrated to provide a set of inferred links within a network. A consolidation is performed among inference engines that operate at a base level of connectivity detail to create a model of the network at this base level. The connectivity information provided by inference engines at each subsequent higher level of connectivity abstraction is then overlaid on the base level connectivity. By separately consolidating the connectivity information at each level of abstraction, the rules for dealing with conflicts can be simplified and/or better focused to resolve the conflict. By assuming that the more detailed lower level information is likely to be more accurate, rules can be developed to modify the connectivity models produced by the higher level techniques to conform to the lower level connectivity details while still maintaining the integrity of the higher level connectivity models.

摘要： A system and method for managing captured network traffic data is provided. The invention comprises a plurality of capture agents, each being configured to capture the network traffic associated with one or more applications. Each application is associated with one or more capture agents according to an application profile that is stored and maintained in a capture server. When analysis of an application's network traffic is required, the capture server contacts the corresponding capture agents according to the application profile. The capture server then effects the identification and archiving of the network traffic that corresponds to a user-defined capture condition. A database at the capture server maintains a record that associates the corresponding network traffic with the user-defined capture condition such that the corresponding network traffic can later be retrieved and analyzed using an analysis engine.

摘要： A user interface to a network simulator facilitates the use of application layer parameters and application layer logic. The user interface is configured to allow the user to define the input in a graphic form, or a text/programming form, or a combination of both. Preferably, the user interface provides common graphic forms for both inputting the data to the simulator as well as for displaying the resultant data from the simulator, thereby easing the progression from the analysis of output from one simulation to the generation of new input for a subsequent simulation.

摘要： Network survivability is quantified in such a way that failure cases can be compared and ranked against each other in terms of the severity of their impact on the various performance measures associated with the network. The degradation in network performance caused by each failure is quantified based on user-defined sets of thresholds of degradation severity for each performance measure. Each failure is simulated using a model of the network, and a degradation vector is determined for each simulated failure. A comparison function is defined to map the degradation vectors into an ordered set, and this ordered set is used to create an ordered list of network failures, in order of the network degradation caused by each failure.

摘要： A graphic user interface facilitates the hierarchical analysis of timing parameters related to network-based applications. At the top level of the hierarchy, the user is presented a summary of the delays incurred while running an application, or while simulating the running of an application, organized by delay categories, including processing delays at each node, as well as propagation delays at each link between nodes. The interface enables a user to “drill down” into lower levels of the timing information hierarchy by ‘clicking’ on currently displayed information. The information is presented in a form most appropriate to the level of analysis. The presentation forms include, for example, pie-charts, multi-variable timing diagrams (in both absolute and relative forms), data exchange charts, and so on, and ‘zoom’ capabilities are provided as appropriate to the particular display form.
