摘要:
The SIP server can be comprised of an engine tier and a state tier distributed on a cluster network environment. The engine tier can send, receive and process various messages. The state tier can maintain in-memory state data associated with various SIP sessions. A near cache can be residing on the engine tier in order to maintain a local copy of a portion of the state data contained in the state tier. Various engines in the engine tier can determine whether the near cache contains a current version of the state needed to process a message before retrieving the state data from the state tier. Accessing the state from the near cache can save on various latency costs such as serialization, transport and deserialization of state to and from the state tier. Furthermore, the near cache and JVM can be tuned to further improve performance of the SIP server.

摘要:
In a system and method for the distribution of identities and reputation on a network, identity and reputation information may be distributed among nodes on a network (e.g. nodes on a peer-to-peer network). Embodiments may allow nodes on the network to evaluate other nodes' reputation using the distributed reputation information. Embodiments may allow nodes to iteratively increase confidence in a determined reputation of a node by determining the reputation of nodes that provide reputation information corresponding to the node. Embodiments may allow nodes to adjust a reputation of other nodes using results of transactions and prior reputations. Determined or adjusted reputation information and/or transaction information may be distributed among the nodes on the network. In one embodiment, transaction information may be divided into segments and the segments may be distributed among the nodes on the network.

Techniques and systems for selecting advertisements for dissemination over a network are disclosed. In one embodiment, an advertisement service stores information indicative of offers from merchants, including information indicating an amount of revenue that the offering merchant would be willing to share with the advertisement service if a consumer consummates a transaction with the merchant based on the good or service advertised in the offer. The service computes predicted conversion rates for these offers, and uses the predicted conversion rates and the revenue sharing information to select an advertisement for dissemination according to which advertisement is expected to generate the greatest amount of revenue for the advertisement service. The predicted conversion rate can be based on various features, including physical location of the consumer, the consumer's preferences on a third-party information sharing service, amount of discount reflected in the offer, the customer service rating of the merchant, etc.
摘要:
A distributed network identity is provided. An identity provider stores a portion of a user's personal information. A service provider accesses user information from one or more identity providers. System entities such as identity providers and service providers can be linked to enable information sharing and aggregation. User policies and privacy preferences are provided to control how information is shared. A single sign-on architecture is provided where an identity provider is used to facilitate cross-domain authentication and to enhance user convenience. Service delegation features are also provided.

摘要:
A method for enhancing the biodistribution of antibody for localization in lesions comprising initially exposing a mammalian subject containing lesion-associated marker substance to a first antibody specific for a given epitope of the marker substance, and after a period of time such that the marker substance has associated with the antibody, exposing the mammal to a further amount of the same antibody, or a second antibody specific either for an epitope of the marker substance different from the epitope for which the first antibody is specific, or for the same epitope of the marker substance as the first antibody but of a different binding affinity from the first antibody.
