Abstract: In order to solve the problem that communication resources (a communication device and a link) in a network are not always efficiently used, this network is provided with a first communication device for transmitting data of a set path and a second communication device for receiving data of the path, wherein a path is set for the second communication device, and the second communication device is provided with a detection means for outputting a first signal in correspondence to a change in the bandwidth of a link connecting the second communication device and an other communication device for which the path is set, and a change indication means for determining, upon input of the first signal, a communication traffic for each path such that the total traffic after a change does not exceed the bandwidth of the link, and transmitting the determined communication traffic to a communication device for transmitting data of the path, the first communication device transmitting data of the path within the received co

Abstract: A communication device includes an address generation unit that generates address information, a reply request transmission unit that transmits a reply request to request a reply from the other communication device having the address information generated by the address generation unit, and an address setting unit that sets the address information generated by the address generation unit as address information of the communication device when the reply to the reply request is not received, wherein the address generation unit generates address information different from the previously generated address information when the reply to the reply request is received.

Abstract: A time slot selection device is provided that can consider resource use states on its own and allocate time slots. The time slot selection device performs time slot allocation, based on data link identifiers that identify a group of data links specified by a path setup request, a time slot size that is information about a required band, and a required number that is the number of contiguous time slots required. In this time slot selection device, a resource allocation section performs time slot selection, based on the resource use state of each time slot. By the time slot selection with consideration given to the use state of each time slot in the group of data links, time slots to be used can be selected so that a maximum number of contiguous usable time slots will be left. Thus, it is possible to efficiently use resources.

Abstract: A node device in an optical transmission network where a manually set path and an ADP (autonomous decentralized protocol) set path coexist, wherein the manually set path is set by centralized control and the ADP set path is set by autonomous decentralized processing, the node device including: a label memory for storing at least first labels used for manually set paths and second labels used for ADP set paths, wherein the first and second labels previously defined before path setting; and a resource manager for setting a manually set path and an ADP set path by referring to contents stored in the label memory.

Abstract: The present invention provides a network system, a network administration apparatus, a communication apparatus, a path setting method and a program that can set a path by autonomous distributed control through an autonomous distributed control non-adaptive apparatus in a network including both an autonomous distributed control adaptive apparatus and the autonomous distributed control non-adaptive apparatus.

Abstract: Verification of the connectivity of a logical link can be accomplished even in a network including a plurality of nodes that are connected through data link(s) and a control channel between adjacent nodes. A node that is the start point of a logical link to be verified transmits a logical link verification request message, over a control channel, to a node that is the end point of the logical link to be verified, thereby notifying that a connectivity verification test will begin. Thereafter, the start-point node transmits a physical link verification message (verification data) over the logical link to be verified. When notified through the control channel that the test will begin, the end-point node carries out the connectivity verification test, based on whether or not it can receive the verification data through the logical link to be verified. The end-point node returns a test result message to the start-point node.

Abstract: When there occurs a fault in any path of the MPLS or GMPLS network, a node which has detected the fault sends a notify message which is fault event information. A node which performs fault recovery receives the notify message (S1) and counting of the waiting time is triggered by this reception (S2). During this waiting time, LSA of OSPF is collected. When the waiting time is terminated, the node which performs fault recovery calculates alternative path based on the notify message and the LSA of OSPF (S3) and carries out fault recovery by restoration (S4).
