Abstract: A system for reducing dynamic power consumption of a wakeup source includes a receiver interface coupled to the wakeup source. A data packet, received by the receiver interface, transmits the data packet to the wakeup source. The wakeup source processes the data packet to identify a predetermined code for initiating a wakeup sequence. The wakeup source is put into a deep sleep mode if it is idle for a predetermined time period.

Abstract: A technique for performing stream output operations in a parallel processing system is disclosed. A stream synchronization unit is provided that enables the parallel processing unit to track batches of vertices being processed in a graphics processing pipeline. A plurality of stream output units is also provided, where each stream output unit writes vertex attribute data to one or more stream output buffers for a portion of the batches of vertices. A messaging protocol is implemented between the stream synchronization unit and the plurality of stream output units that ensures that each of the stream output units writes vertex attribute data for the particular batch of vertices distributed to that particular stream output unit in the same order in the stream output buffers as the order in which the batch of vertices was received from a device driver by the parallel processing unit.

Abstract: Technologies are described herein for relevance-based expiration of data. An initial expiration time for the data is computed based upon an expiration duration associated with the data. The expiration time for the data is periodically re-computed in order to extend the expiration time. A relevance value for the meeting data is computed and the expiration time is set as a function of the computed relevance value. The relevance value may be computed as a product of a user-settable relevance value for the meeting data and a dynamic relevance point for the meeting data. When the computed expiration time for meeting data has been reached, the meeting data is expired, such as through the deletion of the meeting data.

Abstract: A multi-tone synchronous collision resolution system permits communication nodes within a MANET to contend simultaneously for a plurality of available channels. The communication nodes contend for access using a synchronous signaling mechanism that utilizes multiple tones in a synchronous manner to resolve contentions. Contentions are arbitrated locally, and a surviving subset of communication nodes is selected. The communication nodes of the surviving subset then transmit data packets simultaneously across the available communication channels.

More specifically, new and improved P2P application programming interfaces (APIs) and methods for the creation and access of graphs, the retrieval of node and graph information, the addition, modification, deletion and management of records (data), the importation and exportation of graph data, the direct communication between graph nodes, the addition of a security provider to a graph, the setting and retrieval of presence information, the registering for event notifications, and other utility and support functions are presented. Each of these interfaces utilize various parameters that are passed in from an application program that uses these interfaces to manage and utilize graphs. The interfaces return a value that indicates the success or failure of the function. For failures, the interfaces provide an indication as to the problem resulting in the failure.

Abstract: A system, apparatus, method, and computer-readable medium are provided for authorizing a computing node to participate in a group of computing nodes utilizing a shared group password. According to one method described herein, an invitation to join a group is transmitted to a tentative group member node. The invitation is used to establish a connection with a group member node of the group. The tentative group member node generates a hash of a group password and transmits the hash to the group member node. When the group member node receives the hash, the group member node compares the received value to a previously stored hash of the group password. If the previously stored value is identical to the value received from the tentative group member node, then the tentative group member node is authorized as a new member of the group. Otherwise the tentative group member node is not permitted to become a member of the group.

Abstract: A collaborative services platform may include a connectivity service, an activity service and a contact management service. The connectivity service may provide communicative connectivity between users of the collaborative services platform. The activity service may provide one or more collaborative activities supporting various modes of communication. The contact management service may maintain contact information for each of the users of the collaborative service platform. It may be that not every user is capable of participating in every collaborative activity. The contact information maintained by the contact management service may indicate the collaborative activities in which each user is capable of participating. A set of programmatic objects utilized to implement the collaborative services platform may include contact objects, conference objects, MeContact objects, endpoint objects, published objects and presence objects. The presence object may represent a presence of a particular user in a networked computing environment and may reference multiple collaborative endpoints.

Abstract: A security infrastructure and methods are presented that inhibit the ability of a malicious node from disrupting the normal operations of a peer-to-peer network. The methods of the invention allow both secure and insecure identities to be used by nodes by making them self-verifying. When necessary or opportunistic, ID ownership is validated by piggybacking the validation on existing messages. The probability of connecting initially to a malicious node is reduced by randomly selecting to which node to connect. Further, information from malicious nodes is identified and can be disregarded by maintaining information about prior communications that will require a future response. Denial of service attacks are inhibited by allowing the node to disregard requests when its resource utilization exceeds a predetermined limit. The ability for a malicious node to remove a valid node is reduced by requiring that revocation certificates be signed by the node to be removed.

Abstract translation: 提出了一种防止恶意节点中断对等网络的正常操作的能力的安全基础设施和方法。 本发明的方法允许节点通过使其自我验证来使用安全和不安全的身份。 在必要或机会主义的情况下，通过捎带现有消息的验证来验证身份所有权。 通过随机选择连接到哪个节点来减少初始连接到恶意节点的概率。 此外，来自恶意节点的信息被识别，并且可以通过维护关于将要响应的先前通信的信息而被忽略。 通过允许节点在其资源利用超过预定限制时忽略请求，禁止拒绝服务攻击。 恶意节点删除有效节点的能力通过要求撤销证书由要删除的节点进行签名来减少。
