摘要： An ad-hoc discovery protocol improves reliability, security and scalability of multicast and server-based discovery. In switching from multicast to server-based discovery, the discovery client is made responsible for multicast suppression, and not discoverable devices with services. Messages include message identifier and time-to-live parameters to detect recast queries and avoid duplicating replies. A device's announcement message includes endpoint identifier, configuration number and stateless boot time parameters to detect changed device configuration and rebooted state for refreshing cached device and service descriptions. Paging parameters allow a discovery client to control the number of discovery responses returned at a time from a discovery server.

摘要： A method for authenticating and negotiating security parameters among two or more network devices is disclosed. The method has a plurality of modes including a plurality of messages exchanged between the two or more network devices. In a main mode, the two or more network devices establish a secure channel and select security parameters to be used during a quick mode and a user mode. In the quick mode, the two or more computers derive a set of keys to secure data sent according to a security protocol. The optional user mode provides a means of authenticating one or more users associated with the two or more network devices. A portion of the quick mode is conducted during the main mode thereby minimizing the plurality of messages that need to be exchanged between the initiator and the responder.

摘要： A multiuser scheme allowing for a number of users, sets of user, or carriers to share one or more channels is provided. In the invention, the available channel bandwidth is subdivided into a number of equal-bandwidth subchannels according to standard OFDM practice. A transmitter transmits data on a set of OFDM subchannels that need not be contiguous in the spectrum or belong to the same OFDM channel. A receiver receives and decodes the data and detects errors on subchannels. The receiver then broadcasts the identity of those subchannels on which the error rate exceeds a specific threshold, and the transmitter may select different subchannels for transmission based on this information.

摘要： A method to negotiate computer settings in advance is presented. A prediction is made to determine if the computer setting will be needed, and if needed, whether a value outside of a normal range of values will be needed. A value for the computer setting that is outside of the normal range of values is determined and the value is set to the outside value. A value within the normal range of values is used if it was predicted that there is no need for a value outside of the normal range of values.

摘要： Appropriate determinations in a series of tests, which transition from more passive tests to more active tests, control the admission of data streams onto a network data path. More passive tests can include promiscuous mode and packet-pair tests. When the results of more passive tests indicate a reduce likelihood of a data stream causing a network data path to transition into a congested state, the network data path can be actively probed to make a more precise determination on the likelihood of congestion. A train of diagnostic data packets is transmitted at a diagnostic data transfer rate having a significantly reduced chance of causing congestion. A train of target data packets is transmitted at a requested application transfer data rate. The number of target data packets received within a specified delay threshold is compared to the number of diagnostic data packets receive with the delay threshold.

摘要： Systems and methods are disclosed for adapting a communication system to varying conditions. Using some form of discovery protocol, the communication standards supported by at least two communicants are determined. Each communicant may then periodically monitor the quality of the channel established by the communication standard and dynamically select a set of one or more communication standards to use for communicating. Further, when communicants share common non-standard parameterized implementations of communication standards, changes to the protocols which the communication standards comprise can be used to add options for a more dynamic response to changing conditions than is possible when adhering only to an established communication standard.

摘要： A serverless name resolution protocol ensures convergence despite the size of the network, without requiring an ever-increasing cache and with a reasonable numbers of hops. This convergence is ensured through a multi-level cache and a proactive cache initialization strategy. The multi-level cache is built based on a circular number space. Each level contains information from different levels of slivers of the circular space. A mechanism is included to add a level to the multi-level cache when the node determines that the last level is full. A peer-to-peer name resolution protocol (PNRP) includes a mechanism to allow resolution of names which are mapped onto the circular number space through a hash function. Further, the PNRP may also operate with the domain name system by providing each node with an identification consisting of a domain name service (DNS) component and a unique number.
