摘要： Systems may use explicit ratings from users to construct user to user correlations. This technique may reduce the user-content correlation to a single dimension, i.e., the content that a plurality of users may rate similarly. Embodiments of the present invention may use DHT as an underlying distributed signaling mechanism, but may also make the rating implicit. Furthermore, embodiments of the present invention may construct the user to content correlation based on multi-dimensional metadata related to the content.

摘要： In system of DHT rings that are not filly meshed with each other, flooding of PUT and GET messages is limited by PUTting a content key indicating an actual storage location of content from a content provider only to root DHTs associated with the content provider, and PUTting a secondary key indicating a subset of DHT rings at which content from the content provider might be stored only to DHT rings for which the content provider desires the content to be available. When a DHT receives a GET it first determines from the content key whether it can provide the content and if not, the DHT obtains the subset of DHT rings from the secondary key and forwards the GET of the content key to the corresponding root DHTs.

摘要翻译： 在没有彼此互相关联的DHT环的系统中，通过将指示来自内容提供商的内容的实际存储位置的内容密钥与内容提供商相关联的根DHT进行PUT和PUTting的限制来限制PUT和GET消息的泛滥 指示DHT环的子集的次要密钥，来自内容提供者的内容可以仅存储在内容提供者希望内容可用的DHT环上。 当DHT接收到GET时，首先从内容密钥确定是否可以提供内容，如果不是，DHT将从辅助密钥获取DHT环的子集，并将内容密钥的GET转发到相应的根DHT。

摘要： In one embodiment, a node in a computer network joins a global ring associated with a distributed hash table (DHT), and maintains a DHT routing table and DHT database for the global ring. In addition, the node may determine a particular service class for which the node is configured, and may join a particular service-based sub-ring according to the particular service class, where all nodes of the particular service-based sub-ring are within the global ring. As such, a service-based DHT routing table and service-based DHT database may be maintained for the particular service-based sub-ring, such that DHT operations identified by the particular service class are routed to the particular service-based sub-ring (e.g., by a portal node).

摘要： The present invention allows multi-channel communications equipment to detect and eliminate a false interpretation of interference as a valid signal. The solution is based on the observation that the simultaneous arrival of energy on two independent channels is an impossible event. So, when such an event happens, it is a reliable signature of confusing out-of-band energy for a valid signal.

摘要： Upon a triggering event, a delay chain shifts data out at a higher rate than incoming packets and a processor controls bypassing circuitry to reduce the latency of hardware implementations of, for example, 802.11a OFDM receivers, with long delay chains. The signal processing algorithms used to recover symbol timing need a large number of samples stored in a delay chain, often consisting of pipelined registers. Such a delay chain introduces a large lag between the time samples have been acquired by the data converters and the time they are processed. This delay makes it difficult for higher level network layer implementations to meet the deadlines of 802.11a WLAN protocol. The proposed scheme implements dynamic reduction in the depth of the delay chain once timing recovery has been performed. A multi-step scheme achieves exponential reduction in the number of elements in the delay chain in every step.

摘要： Using a combination of auto-correlation and cross-correlation techniques provides a symbol timing recovery in a Wireless Local Area Network (WLAN) environment that is extremely robust to wireless channel impairments such as noise, multi-path and carrier frequency offset. An auto-correlator provides an estimate for a symbol boundary, and a cross-correlator is subsequently used to more precisely identify the symbol boundary. Peak processing of the cross-correlation results provides further refinement in symbol boundary detection. In receiving a packet conforming to the IEEE 802.11a standard, the method requires a minimum of only three short symbols of the 802.11a short preamble to determine timing, and guarantees timing lock within the duration of the 802.11a short preamble. This method and system can be easily applied to any other preamble based system such as 802.11g and High Performance Radio LAN/2 (HIPERLAN/2).

摘要： To support local number portability and service portability in a telephone network, a method and apparatus handle subscription and administrative service requests in a local service management system to maintain records at a service control point. The subscription requests include create, modify, and delete requests of records in the service control point. The administrative service requests include Numbering Plan Area (NPA) code split, mass change, and query and resend requests. The records at the service control point are accessible by switches via respective signal transfer points to determine the network addresses of the switches handling services and calls corresponding to a particular telephone number.
