摘要:
A voice-quality evaluating system, in a secure network that allows a voice packet to pass, transmits and receives communication information for a voice quality testing between a test management apparatus and a test communication apparatus connected to the network and between the test communication apparatuses, for the voice quality testing between the test communication apparatuses arranged on the network. The voice-quality evaluating system embeds the communication information in a payload of the voice packet, and transmits and receives communication-information-embedded voice packet.

摘要:
A communication system is installed in information home appliances controlled by an operation system connected to an IP network. The communication system includes a first communication apparatus connected to the IP network; and a second communication apparatus connected to the first communication apparatus. The first communication apparatus includes a determining unit for determining, based on an attribute included in a search signal transmitted from the second communication apparatus in order to search for the first communication apparatus, whether the first communication apparatus can control the second communication apparatus; a search-signal response signal generating unit for generating and transmitting, to the second communication apparatus, a response signal in response to the search signal in the case the determination of the determining unit is affirmative; and a registering unit for registering the second communication apparatus as a control target based on a connection request made by the second communication apparatus.

An operation management system for managing operation of a network-connected apparatuses includes an apparatus operation managing agent and a management server. The apparatus operation managing agent is provided in the network-connected apparatus to be managed, and independently manages an operational state of the network-connected apparatus, and autonomously sends, through a network, a management result of the network-connected apparatus managed. The management server receives the management result through the predetermined interface, and manages the received management result so as to manage the network-connected apparatus to be managed.
摘要:
A protocol conversion system that provides improved reliability in data transmission and reception. The system comprises a first node belonging to a network A, a second node belonging to another network B, and a protocol converter disposed between the two nodes. The first node uses a first communications protocol that defines a set of rules for communications in the network A, while the second node uses a second communications protocol for the network B. Serving as a relaying device between the first node and second node, the protocol converter converts the communications protocol of the messages traveling between them. The protocol converter comprises a first message processor to process the messages according to layer definitions of the first communications protocol, a second message processor to process the messages according to layer definitions of the second communications protocol, and a first protocol converter that adds and removes some control information to/from the messages for protocol conversion. The second node comprises a second protocol converter working as a counterpart of the first protocol converter.
