A P2P content caching system, method, and computer program product for a P2P application on a computer network device. The system includes: a content analyzer; and a content manager. The method includes: determining P2P hotspot downloading contents of the P2P application on the computer network device; downloading the determined P2P hotspot downloading contents into a local memory, and requesting a directory server of the P2P application to register a P2P content caching system as a P2P content provider of the downloaded P2P hotspot downloading contents; and providing the downloaded P2P hotspot downloading contents to a P2P participant in response to a request from the P2P participant to the downloaded P2P hotspot downloading contents.

P2P content caching system and method

A method for generating a Simple Object Access Protocol (SOAP) message in XML during execution of a process in a SOA-based process engine apparatus and a corresponding process engine apparatus. The method includes: generating and storing an XML character string containing a fixed SOAP message skeleton; generating and storing an XML character string containing an instance-constant variable; generating an XML character string containing a dynamic variable; and concatenating the XML character string containing the fixed SOAP message skeleton and the XML character string containing the instance-constant variable as previously stored and the XML character string containing the dynamic variable by a character string concatenating operation to generate a SOAP message. A process engine apparatus including a message analyzer unit, a message pre-composer unit, a character string depository, and a message composer unit is also provided.

Method for generating simple object access protocol messages and process engine

A method, apparatus, system, and computer readable medium for authenticating the identity of a caller. An authentication device authenticates a caller's identity based on received information of the caller and an identifier generation device generates an identifier containing the caller's identity. The authentication information is supplied to a mobile telephone user acting as a callee. Therefore, the callee knows the caller's identity, thereby providing a secure delivering channel.

Authenticating identity of caller

A method and a computer system for making a computer achieve high availability. The method includes running a host virtual machine on a host virtual machine container; running a servant virtual machine on the servant virtual machine container; and synchronizing the host virtual machine and the servant virtual machine by using an I/O instruction. The system includes at least two computers including a host computer and a servant computer, each computer including a virtual machine container; a virtual machine running on the virtual machine container; and a communication channel making the virtual machine container execute a virtual machine synchronization operation. The virtual machine synchronization operation of the virtual machine container is triggered by the virtual machine executing I/O instructions.
