The present invention relates to a state machine which has a dual process which receives and concurrently processes ad-hoc and infrastructure processes. The dual process state concurrently executes both processes by either over-clocking a media access control core, or by routing the processes to multiple media access control cores for processing. The state machine contains an ad-hoc process state which accepts either an ad-hoc or an infrastructure signal, and either processes the signal if the received signal is an ad-hoc signal, or transfers control to an infrastructure process state for processing if the received signal is an infrastructure signal. The state machine also contains an infrastructure process state which accepts either an ad-hoc or an infrastructure signal, and either processes the signal if the received signal is an infrastructure signal, or transfers control to an ad-hoc process state for processing if the received signal is an ad-hoc signal.

Wireless state machine and multiplexing method for concurrent ad-hoc and infrastructure mode service in wireless networking

Managing a plurality of multifunction network devices on a network, each multifunction network device having a plurality of hardware resources including a storage memory for storing a plurality of function modules, a program memory for use by the function modules and a processor for executing each of the function modules, including detecting a reconfiguration event for one of the plurality of multifunction network devices, sending a reconfiguration command to the one multifunction network device, the reconfiguration command being a deletion command to delete at least one of the function modules or an allocation command to reallocate an amount of at least one of the hardware resources available for use by each of the plurality of function modules, and receiving confirmation that the one multifunction network device has been reconfigured in accordance with the reconfiguration command.

Dynamic network device reconfiguration

Managing a plurality of network devices on a network by detecting the presence of at least one of the plurality of network devices on the network by using a first communication protocol, obtaining, by using the first communication protocol, an information block from each of the detected network devices, wherein the information block contains information related to the corresponding network device, formatting each information block into a directory entry, and sending each directory entry to a directory server via a second communication protocol.

Directory-enabled device management

A method and system for providing an application that uses real-time communication to order products and/or services. The method and system comprise launching a real-time chat application on a client device, logging into the real-time chat application, initiating a discovery operation of the client device upon logging in, displaying peripheral devices connected to the client device detected by the discovery operation, selecting a peripheral device from the detected peripheral devices, displaying products and/or services for the selected peripheral device, and obtaining products and service for the selected peripheral device.

Leveraging instant messaging presence to drive sales opportunities

Managing a plurality of network devices on a network, including detecting an address assignment message sent from an address server over the network to a network device, the address assignment message containing an assigned address corresponding to the network device, sending an information request message, in response to the detection of the address assignment message, over the network from the network management device to the network device, the information request message containing the assigned address corresponding to the network device, receiving information, in response to the information request message, from the network device, and creating an entry corresponding to the network device in a device management directory, the entry containing the assigned address corresponding to the network device and the information received from the network device.

Discovery and management of network printers

Managing an SNMP device over a network by transmitting SNMP messages to the managed device while ensuring that an SNMP packet identifier for each message is unique. The SNMP packet identifier is selected in correspondence to the physical memory address at which the SNMP message is stored, and may be the first or last such memory address, or any memory address in between. Because the packet identifier corresponds to the physical memory address of the message, each packet identifier is guaranteed to be unique since subsequent messages cannot occupy the same physical memory address as a prior message unless the prior message is already safely gone.

Assigning unique SNMP identifiers

Viewing and updating a configuration of at least one of a plurality of network devices connected to a network. Each of the network devices is repeatedly polled over the network by a network management server for configuration information, which is stored in a database. A first URL-encoded request is received from a requesting station, which is preferably a web browser. The first request identifies a targeted one of the network devices. Responsive to the first request, a response is dynamically generated. The response is representative of a visual display of the configuration information for the targeted one of the network devices based at least in part on the configuration information stored in the database. The response is sent to the requesting station, and a second URL-encoded request is received from the requesting station, the second request including configuration data for the targeted one of the network devices. Responsive to the second request, the database is updated based on the configuration data. The configuration of the targeted one of the network devices is updated by the network management server based on the updated database.

Browser-based network management allowing administrators to use web browser on user's workstation to view and update configuration of network devices

Management of a network device by a management client over a network using a network management protocol such as SNMP or DMI, with the managed device including multiple different protocol stacks for receiving network transmissions using multiple different protocols respectively corresponding to the multiple different protocol stacks. The management client obtains information from the managed device pertaining to the presence and identity of the multiple different protocol stacks. Thereafter, to manage the managed device, the management client sends multiple copies of the same network management packet to the same recipient over each of the different protocol stacks. If a single managed device includes plural different network interfaces, then multiple transmissions are also made to each different network interface. By virtue of this arrangement, since multiple copies of the same network management packet are sent to the same recipient, reliability of receipt of the management packet is increased.
