A communication control method for a network system includes establishing a first communication path from a first virtual machine to be executed at a first information processing device to a second virtual machine to be executed at a second information processing device, using a plurality of switch devices, and establishing a second communication path from the first information processing device to a third information processing device using the plurality of switch devices, which differs from the first communication path, before moving the second virtual machine from the second information processing device to the third information processing device.

Network system and communication control method

In a communication system environment, access points which transmit/receive information by wireless communication, a mobile terminal which moves in a utilization environment and transmits/receives information by wireless communication, and a wireless tag of a weak radio wave which transmits/receives information by wireless communication of weak transmission power smaller than the transmission power of the access points and the mobile terminal are disposed. The mobile terminal transmits a special CTS frame including a MAC address, which cannot exist in the utilization environment, and transmission planned time upon communication with the wireless tag. The access points which have received the special CTS frame prohibit transmission operation for the transmission planned time in the frame, and, during that period, the wireless tag transmits position information or the like to the mobile terminal without being interrupted.

In object collaboration via a message, various message types are dealt with. Furthermore, synchronization processing between objects is conducted easily and flexibly. A message type is previously classified and arranged hierarchically. A message/action reaction tablearranged on the message type basis is held in a message/action reaction relationship storing part. A received message is subjected to matching by a message type classifying/matching part. When the received message is matched with a message type dealt with by the message/action reaction relationship storing part, the message is given to an action executing part. When the received message is not matched with a message type dealt with by the message/action reaction relationship storing part, the message is discarded.

Object collaboration apparatus using message type

A policy that relates attributes of an agent to a role is distributed to each agent on a network. A field connector generates an internal field in accordance with an instruction of a security manager. A ROLE manager uses attribute information from an attribute manager, and assigns each agent a ROLE in accordance with the attributes of each agent, and installs a ROLE method table and a ROLE execution part. When receiving a message from an external network, each agent searches for a corresponding ROLE by referring to the ROLE method table, and executes the ROLE. Thus, collaboration among agents is realized through a virtual communication channel based on the exchange of a message.

Object collaboration apparatus

A machine-translation/electronic-mail system comprises an electronic-mail receiving unit, an electronic-mail transmitting unit, a standard dictionary used in a machine translation process, and a private-use-word registering apparatus. The private-use-word registering apparatus comprises a word-definition recognition unit for recognizing a word-definition command for defining a private-use word used by a specified user, the word-definition command existing in an electronic mail containing a document, and a temporarily registering means for temporarily storing in a private-use word dictionary the private-use word having been extracted by the word-definition recognition unit, the private-use word dictionary being temporarily used in the translation as the private-use word dictionary.
