A system and method of assigning an identifier to an entity operating within a mobile device ecosystem including a domain are provided. The method comprises: obtaining an identifier of the entity which uniquely identifies the entity within the domain, the identifier of the entity including length information identifying the length of identifier of the entity; obtaining an identifier of the domain within which the identifier of the entity is unique; and combining the identifier of the entity with the identifier of the domain to create a globally unique identifier of the entity which is globally unique in the mobile device ecosystem.

Method and system for identifying an entity in a mobile device ecosystem

A method and a system for identifying unauthorized accesses to a data network service by a particular node in a data network is disclosed. The NMC communicates with an agent periodically to gather a list of users of the service node. An agent is installed on the service node to monitor all network accesses to the service. By configuring the agent to monitor all access to the service node, through SNMP or a similar protocol, the agent maintains a list of all accesses to that service node. This list is stored internally by the agent and queried for by the NMC periodically. The access information stored by the agent is periodically retrieved by the NMC for all monitored nodes and compared with the authorization list for the node. If unauthorized accesses are found, they are identified by the NMC. These unauthorized accesses can be notified to the appropriate entity in a number of ways such as through paging, email or a report viewable through the NMC.

Method and system for a network management console

Methods which determine network performance by determining not only the transit delay between nodes in a network but also the variance, or jitter, of such transit delays. A common node, usually a network management computer (NMC), sends out a signal to a first node of interest and measures the time before it receives an acknowledgment from the first node. The NMC then sends out a similar signal to a second node of interest and similarly measures the time required to receive an acknowledgment. Based on these two measurements, the transit delay between the first and second nodes can be calculated if the first node lies on the path between the NMC and the second node or vice versa. For a multiple node communications path, the total transit delay between any two nodes is the sum total of the transit delays between adjacent nodes lying on the path. In the case of meshed networks, where a path to a node may be ambiguous, additional measurement nodes strategically positioned in the network can be used such a way that the transit delay between any adjacent pair of nodes can be calculated unambiguously from at least one of these measurement nodes, i.e., the portion of the network being measured will be reduced to a hierarchical one with respect to at least one of the measurement nodes.

Method for determining the delay and jitter in communication between objects in a connected network

A method of determining a connection between a data emitting device j having address IP(j) and a data receiving device i having address IP(i) via a routing device, wherein the routing device utilizes a management information database MIB, establishing a mask field in the MIB for all devices in a subnet which passes data through the routing device having a property(() AND MASK)=(() AND MASK),and indicating connection of a device i to a device j for devices in which the property is true.

Method of determining the topology of a network of objects

A method of determining a connection between a data emitting device and a network device which may carry the data, wherein the network device is comprised of a store for a data source address of a last frame transmitted to the network device and an input traffic count comprising: (a) periodically reading the data source address, (b) periodically reading the input traffic count, (c) determining whether the data source address has always stayed the same, (d) in the event the data source address has always stayed the same, determine whether the traffic count has exceeded a predetermined threshold, (e) in the event the result of step (d) is true, indicate that the data source address identifies with acceptable probability a data emitting device directly connected to the network device.

A method of determining the topology of a network comprising: transmitting a signal comprised of a sequence of bursts of packets formed of orthogonal signals, monitoring devices in the network including the destination device for reception of the signal, and defining a sequence of devices within the network by sensing a sequence of reception of the signal in the devices from the source device toward the destination device.

A method of determining network topologies comprising monitoring traffic received by devices connected in the network and traffic emitted out of the devices, correlating traffic out of the devices with traffic into the devices, indicating a network communication path between a pair of the devices in the event that the correlation of traffic out of one of the pair of the devices and into another of the pair of the devices is in excess of a predetermined threshold.
