摘要： There is provided a communication delay time derivation method for calculating a communication delay time depending on a combination of channels set between communication terminals on a communication path in the MCH/IF environment. When selecting a channel to be used for communication in each section on the communication path per section between communication terminals on the communication path, a calculation target section specification means 82 detects an inter-terminal selected channel repetitive pattern as a pattern of the selected channels cyclically appearing on the communication path, and defines a section corresponding to the inter-terminal selected channel repetitive pattern as a communication delay time calculation target section. A communication delay time derivation means 83 derives a communication delay time in the calculation target section based on the inter-terminal selected channel repetitive pattern.

摘要： Each of nodes A through Z calculates delivery predictability for a destination node and exchanges the delivery predictability as an SV message with an adjacent node. At this time, the delivery predictability calculated in each of the nodes A through Z is transmitted together with a next hop node for the destination node. Upon receiving the delivery predictability for the destination node and the next hop node for the destination node, each of the nodes A through Z checks whether or not the next hop node matches the local node itself, wherein whey they match with each other, the delivery predictability is not registered with a delivery predictability database. Since the node transmitting the delivery predictability is not selected as the next hop node for the destination node, it is possible to prevent the occurrence of a routing loop between nodes.

摘要： A data communication apparatus determines whether the error type is a burst error or not based on an error occurrence state of the data received from a data transmitting apparatus and transmits error type-basis error information. The data communication apparatus receives the error type-basis error information and sets the redundancy degree of an FEC processing section based on the error rate of the errors other than a burst error.

摘要： A node device 100 is configured to: allocate a channel for communication to each of radio interfaces; between the radio interface and a radio interface which is included by an adjacent node device and to which the same channel as the channel allocated to the radio interface is allocated, establish a communication link using the channels; and, by using a communication link (a use communication link) set for the destination of received data among established communication links, transfer the data to the adjacent node device. The node device 100 specifies an unused channel that is other than a channel used by a communication link set as the use communication link among already allocated channels (101), and releases allocation of the unused channel (102).
