When an ad hoc network is formed between short range wireless devices, at least one device assumes the role of an ad hoc network information provider for the new piconet. In this role, the device allocates a browsing hierarchy of service classes in its service registry. The service classes will provide a record to characterize the ad hoc network. When a new wireless device arrives within the communication range of any member of the ad hoc network, its inquiry signals are answered by the first member detecting the inquiry. If that first member is an ad hoc network information provider, it responds with information accessed from its service registry characterizing the ad hoc network. If, instead, an ordinary device in the ad hoc network is the first to respond to the inquiry signals of the arriving device, the device responds with the address of the ad hoc network information provider. The arriving device then pages the ad hoc network information provider to obtain information characterizing the ad hoc network.

A system providing methodologies for automatically detecting when a computing device is plugged into a new network is described. The system includes methods for detecting a connection to a new network by receiving notice of, and evaluating, changes to an existing network configuration. The system profiles and generates an identity for the new network. This includes collecting information about the network to uniquely identify it and generating a unique identifier for the network. Once a network has been profiled, a user may decide whether or not to include it as part of a trusted zone. Alternatively, this decision may be guided by policy established by a system administrator or user. The system automatically reconfigures a firewall to include or exclude the network from the trusted zone based upon this decision. The profile of each network is stored so that the next time the device is connected to the same network it remembers the network and applies the same security settings previously adopted. The stored profile also facilitates the detection of changes to the network configuration or the connection to a new network.

The present invention is directed to a sensor network that includes a number of sensor units and a base unit. The base station operates in a network discovery mode (in which network topology information is collected) in a data polling mode (in which sensed information is collected from selected sensory units). Each of the sensor units can include a number of features, including an anemometer, a rain gauge, a compass, a GPS receiver, a barometric pressure sensor, an air temperature sensor, a humidity sensor, a level, and a radiant temperature sensor.

A policy component comprises policy configuration information. The policy configuration information contains one or more rules. Each rule and group of rules can be associated with a set of response actions. As the nodes on the monitored networks change or intrusive actions are introduced on the networks, network change events or intrusion events are generated. The policy component correlates network change events and / or intrusions events with network map information. The network map contains information on the network topology, services and network devices, amongst other things. When certain criteria is satisfied based on the correlation, a policy violation event may be issued by the system resulting in alerts or remediations.

A resource discovery and description mechanism for decentralized device and service description and discovery in networking environments is described that generates advertisements in a uniform description format to describe resources on a network. The mechanism may translate resource descriptions from other resource description and discovery protocols to generate the advertisements. The advertisements may be used for cross-network discovery and access of the resources. An advertisement may include, but is not limited to, physical endpoints, virtual endpoints, user-extensible metadata, location information, and a universal unique identifier (UUID) for the associated resource. If a resource cannot provide a UUID, the mechanism generates a UUID for the resource. One embodiment may support proxy nodes for generating advertisements for resources that cannot participate directly in the resource discovery and description mechanism. These proxy nodes may also serve as a proxy between local subnetwork discovery and cross-network discovery of the advertisements.

Control information is exchanged between a component and a remote control device or a server using RFID or using network discovery procedures.

A method and system for offloading I / O processing from a first computer to a second computer, using RDMA-capable network interconnects, are disclosed. The method and system include a client on the first computer communicating over an RDMA connection to a server on the second computer by way of a lightweight input / output (LWIO) protocol. The protocol generally comprises a network discovery phase followed by an I / O processing phase.

During the I / O processing phase, the client posts I / O requests for offloading to the second machine over a mutually-authenticated RDMA channel. The I / O model is asymmetric, with read operations being implemented using RDMA and write operations being implemented using normal sends. Read and write requests may be completed in polling mode and in interrupt mode. Buffers are managed by way of a credit mechanism.
