An approach is provided for managing split and merge operations for information spaces with respect to their information content.

Method and system of splitting and merging information spaces

An approach is provided for selective sharing of semantic information sets in a smart space interoperable across platforms, devices, and equipment. A personal smart space application creates a personal information space for a user, wherein the personal information space includes a plurality of semantic information sets. Thereafter, the personal smart space application receives a request for selective sharing of the semantic information sets, and merges, in response to the request, a projection of the selected semantic information sets into a shared information space.

Method and apparatus for selective sharing of semantic information sets

Exemplary embodiments of the present invention provide a method comprising receiving, at a node, an address assignment message, allocating, by the node, a predetermined address interval of an available address space to a respective port of the node which predetermined address interval is defined in the address assignment message, and assigning at least one address for performing communication via a respective port starting with a center address of the predetermined address interval of the available address space allocated for the port concerned. Further, exemplary embodiments of the present invention also relate to respective devices and system.

Address assignment protocol

An approach is provided for retrieving ordered content via a service endpoint. A radio frequency memory tag is preloaded with content managed by a service platform. A request is generated for content stored on the radio frequency memory tag of an endpoint associated with the service platform. Transmission of the request to the endpoint is initiated. The request for the content is received from a user equipment. Transmission of the content is initiated from the memory tag to the user equipment. The user equipment receives the content from the memory tag in response to the request.

Method and apparatus for retrieving content via a service endpoint

An approach is provided for coordinating media presentation on devices via an information space. In response to a request for presentation of media content, a media provision coordinating application retrieves from an information space raw media content corresponding to the request. The media provision coordinating application determines one or more first devices for pre-processing the raw media content and one or more second devices for presenting pre-processed media content based upon respective technical capabilities and availabilities of the first devices, the second devices, or a combination thereof, the first and second devices are connected to the information space.

The present invention provides, according to one example, a method of route aggregation in a network. The network may include at least two switches connected by a link. The method includes the steps of arranging virtual connection identifiers (VCIs) into groups based on a common prefix. Each of the groups corresponds to an outgoing port of a next switch. The method further includes the steps of allocating a VCI at the incoming port of the next switch, and informing the outgoing port of the previous switch of the allocated VCI number. The step of arranging may include splitting all available VCIs into N subgroups, where N is the number of outgoing ports on the switch on the other end of the link.

Aggregation of VCI routing tables

Apparatus configured to receive a first end-to-end flow control representation for at least one logical connection from a first further apparatus to a second further apparatus, update at least one end-to-end credit value for the at least one logical connection from the first further apparatus to the second further apparatus dependent on the first end-to-end flow control representation, select at least one logical connection to the second further apparatus dependent on the end-to-end credit value, generate a second end-to-end flow control representation for the at least one logical connection to the second further apparatus, and transmit the second end-to-end flow control representation addressed to the second further apparatus.

Method and apparatus for using layer 4 information in a layer 2 switch in order to support end-to-end (layer 4) flow control in a communications network

An apparatus for compressing data and optimizing transfer of the compressed data via a wireless link(s) may include a processor and memory storing executable computer code causing the apparatus to at least perform operations including compressing one or more samples of data corresponding to at least one image based in part on generating a plurality of wavelet coefficients. The wavelet coefficients correspond to the sampled data. The computer program code may further cause the apparatus to generate one or more messages including at least one of the wavelet coefficients. Each of the messages may include content denoting that one or more detected errors below a predetermined threshold are insufficient to inhibit reconstruction of the image. The computer program code may further cause the apparatus to enable transmission of the messages to a device(s) via at least one wireless link. Corresponding methods and computer program products are also provided.

An approach is provided for dynamic modification of inference rules and deduction engines in an information base. Authorized agents are allowed to insert, delete or modify inference rules and deduction engines dynamically by signing their input using an authorized signature. Additionally, the functionalities of dynamic modification of inference rules and deduction engines can be provided through a direct application programming interface (API).

Method and apparatus of dynamic rules insertion by agents

In a packet transmission system that uses checksums, partial checksum calculations may be performed during periods of processor underutilization while the data is awaiting final output processing for transport. A system wide checksum service process may coordinate checksum calculations across multiple network protocol layers. The checksum calculations for the buffered data may be performed according to a priority assigned to the buffered data. For example, buffered data whose transmission is imminent may have a higher priority than buffered data that will be transmitted at a later time. Applications that generate data for transmission may register those portions with the service for checksum calculation. To simplify the process, a metadata structure may be created for the data portion, and used to manage the checksum calculations.

System and method for pre-calculating checksums

An approach is provided for efficiently searching information in an information space utilizing information signatures. A signature application receives queries over information sources. The signature application, for each of the queries, generates a polynomial by defining the each query against the information sources as input parameters in polynomial form. The signature application provides irreducible polynomials over a finite field of a degree of orthogonality by factoring polynomials generated from the queries. The signature application adjusts the degree of orthogonality of the irreducible polynomials to provide adjusted irreducible polynomials, each of which is a signature and corresponds to a signature fragment, such that the signature fragments have overlapping portions. The signature application causes at least in part storage of the signatures or the signature fragments in a signature domain over an information space.

Method and apparatus for creating and utilizing information signatures

A node configured to communicate with at least one further node. The node includes a buffer configured to receive data transmitted from the at least one further node. The node also includes an output configured to transmit data to the at least one further network element. The data includes information about the ability for the buffer to receive further data transmitted from the further node.
