Providing selective peer-to-peer monitoring using MBeans by providing a federation of peer-to-peer network servers based on the MBeans, and enabling each of the peer-to-peer networks servers to selectively monitor data associated with at least a subset of the peer-to-peer network servers using at least one of the MBeans.

A network system according to the present invention includes: a server that provides a content to a communication terminal; a relay device that establishes a connection with the server; and a DNS server that stores an IP address of the server. When accepting an inquiry of the IP address of the server being a providing source of the content from the communication terminal, the relay device inquires the IP address from the DNS server, and performs in parallel processing of transmitting the IP address received in response to the inquiry to the communication terminal, and processing of establishing a connection with the server assigned the IP address.

An example framework and method facilitate instrumentation and management of computing environment resources, wherein the resources are distributed across various servers of the computing environment. The example framework employs a distributed synchronized tree or registry of information describing servers (e.g., MBean servers) and associated resources (e.g., as may be represented by MBeans) of the computing environment. A replica of the tree is maintained by each server. The tree facilitates peer-to-peer networking between participating servers for the purposes of discovering and sharing access to software management functionality (e.g., as may be provided via MBeans) offered thereby, and obviates reliance upon a centralized management server or network node to provide management functionality for all participating computing resources that may be distributed across servers of the network.

Systems, methods and computer program products for aliasing of named data objects (in named data networks) and entities for named data networks (e.g., named graphs for named data networks). In various examples, aliasing of named data objects may be implemented in one or more named data networks in the form of systems, methods and/or algorithms. In other examples, named graphs may be implemented in one or more named data networks in the form of systems, methods and/or algorithms.

A method for providing additional information relating to primary information accessible via a network, preferable the Internet, is disclosed. The method comprises the steps of: accessing or referencing primary information by an application using address information, said application running on a user equipment, said user equipment running an operating system, extracting said address information via a system interface provided by said operating system, thus generating extracted address information, wherein said extracted address information is part of a data object generated by said system interface, forwarding said extracted address information to a retrieving entity, retrieving additional information based on said extracted address information by said retrieving entity, and forwarding said additional information back to the user equipment for further processing. Besides that, an according system and a computer program product is disclosed.

An iOS device-based webpage blocking method, being applied to an iOS device comprising application programs and system components, the method comprising: an application program conducts sub-classing on a system default uniform resource locator (URL) caching object to obtain control of a network request; matching the URL character string parsed from the request message with a link character string; if the matching is successful, then generating pseudo response data and displaying according to the pseudo response data, thus blocking webpage advertisements or malicious webpages, reducing occupying of system resources and network resources, improving system operation speed and speed and smoothness of user network access, and lowering device power consumption. The present invention solves the problem in the prior art of resources being occupied by webpage advertisements or malicious webpages.
