摘要： According to an embodiment, a communication apparatus controls controllable nodes. The apparatus includes an acquisition unit and a generation unit. The acquisition unit acquires at least one of a first evaluation value indicating an occurrence frequency of a control request to a target controllable node and a second evaluation value indicating an occurrence frequency of communication error at the target controllable node. The generation unit generates identification information to be assigned to control the target controllable node in a manner such that a bit length of the identification information becomes shorter as at least one of the first evaluation value and the second evaluation value increases.

摘要： A transfer unit transfers a message between a network and an external terminal. An input unit inputs a user ID for identifying a user. A generating unit generates a registration message requesting a registration of address information of the user. A transmitting unit transmits the registration message to a server. A receiving unit receives a response message including registration information and connection information from the server. When the connection information indicates a permission of a connection of the external terminal to the network, a control unit controls the transfer unit to transfer the message between the network and the external terminal.

摘要： The transferring unit transfers a message received from a PC or a network to a designated destination address. The judging unit judges whether an authentication message including the identification information of the user and a grant message indicating that the user is authenticated are transferred. The identification information acquiring unit acquires the identification information from the transferred authentication message. The SIP message processing unit creates a registration message that includes the address information of the user having the acquired identification information and transmits the created registration message to the SIP server when the grant message is transferred.

摘要： A storage unit of a relaying apparatus stores first identification information that identifies an SIP terminal and second identification that identifies other SIP terminal which is forecast as a transfer destination of a message. A transmitting-and-receiving unit receives from the SIP terminal a request message that is received before a transfer message to be transferred to other SIP terminal and that includes a processing request concerning communications and the first identification information. An obtaining unit obtains from a storage unit the second identification information corresponding to the first identification information included in the received request message. A connection establishing unit establishes communications between the other SIP terminal of the obtained second identification information and the relaying apparatus.
