Abstract: A server-handoff system facilitates replicating or migrating a data collection or service to one or more alternative servers of a distributed service. During operation, the system can detect a data-handoff condition for migrating or replicating data to an alternative or newly started server, and determines a namespace that is to be migrated or replicated. The namespace includes a data collection or an application publication space associated with one or more structured name prefixes. The system then identifies the alternative servers to which the namespace is to be replicated, and synchronizes a namespace configuration with the alternative content producer. The namespace configuration identifies a set of data items from the namespace which facilitates the alternative content producer to host the data or service. The alternative content producer can use the namespace configuration to obtain the data items associated with the namespace before hosting the data or service.

Abstract: A data-processing system facilitates processing a data stream to assist other devices to pre-fetch elements of the data stream, out-of-sequence, for uninterrupted playback. During operation, the system can receive a data file, and segments the data file into a sequence of content objects. The system then determines a target content object that is to be processed out-of-sequence, and a corresponding source content object. The system then inserts a reference to the target content object, into the source content object, and stores the sequence of content objects. A client device can disseminate interest to obtain the data stream's content objects. Upon receiving a content object, the client device can determine whether the content object includes a reference to other content objects. If so, the client device can disseminate interests for these referenced content objects.

Abstract: A data-caching system facilitates pre-loading a cache with content objects that are likely to be of interest to a client device, as determined based on their correlation to other content objects served to the client device. During operation, the system can receive an interest for a content object, and can determine whether the local network device can satisfy the interest. If so, the system generates a content-object recommendation that indicates other content objects that are correlated with the received interest, for example, by computing correlation values between the received interest and a plurality of historical interests. The system then provides the content recommendation to a remote network device from which the interest originated, such that the content recommendation indicates the correlated content objects to pre-load into a cache.

Abstract: A system for conducting a conference call based on a community document. The system includes a data network, a first conference client device and a second conference client device communicatively coupled to the data network, wherein the first conference client device is associated with a first user of the conference call and the second conference client device is associated with a second user of the conference call, and a conference server device communicatively coupled to the data network.

Abstract: A method for modifying an object involves determining a modification rate for the object, creating a first reservoir and a first wicking channel based on the modification rate, where the first reservoir and the first wicking channel are on the object and the first wicking channel is operatively connected to the first reservoir, and filling the first reservoir with a chemical for modifying the object, wherein an amount of chemical in the first reservoir is determined based on the modification rate.

Abstract: A method and a system for audio communication between a plurality of users at a plurality of sites utilizes a set of audio input sensors at each site. Each set of audio input sensors binaurally senses an auditory space in proximity thereto. A metaphorical representation of each of the sites is provided. Each metaphorical representation has a position which is variable within a metaphorical space. The metaphorical representations can be based upon, for example, a physical metaphor, a visual metaphor, an auditory metaphor, or a textual metaphor. The auditory space sensed at each site is combined to form at least one synthetic auditory space. The at least one synthetic auditory space is formed in dependence upon the position of each metaphorical representation within the metaphorical space. A binaurally perceivable auditory environment is produced at one or more sites based upon the at least one synthetic auditory space.
