摘要： PROBLEM TO BE SOLVED: To control dynamically data quantity distributed to each reception terminal by each reception terminal in response to a congestion state relating to each of a plurality of the reception terminals. SOLUTION: When a packet loss rate discriminated by an RR(reception report) returned from a reception terminal 30A is very low, an adaptive control mixer 20 delivers as they are communication data scent from a transmission terminal 10 to a reception terminal 30A. When a packet loss rate discriminated from the RR returned from reception terminals 30B, 30C is as high as 50% and 90% respectively, the adaptive control mixer 20 delivers communication data sent from the transmission terminal 10 to the reception terminal 30B by decreasing the quantity, e.g. by 50% and to the reception terminal 30C by decreasing the quantity, e.g. by 90%.

摘要： PROBLEM TO BE SOLVED: To appropriately assign communication resources by declaring a charge which can be provided at the time of distribution for every communication data requiring distribution and deciding a combination of the communication data and a distribution method on the basis of the capability of a communication line to which declaration contents of each receive node and each node are connected so that the total amount of the charge provided by each receive node becomes large. SOLUTION: A reservation request list is prepared for the reservation request to be transmitted from a relay node M2 to an upper order node based on the reservation request transmitted from each downstream node. At the interchange node M2, charges registered with the reservation request transmitted from each receive node B and C are added for each stream and a reservation request list 11b, in which the total charge of a stream #1 is '4', the total amount of a stream '2', and the total charge of a stream #3 is '5', is prepared. Also at a relay node M1, a reservation request list 11a is prepared based on the reservation request transmitted from each downstream node and on the basis of this, the reservation request is transmitted to a transmission node S.

摘要： PROBLEM TO BE SOLVED: To reduce a processing time by introducing a method by a dynamic hierarchical hash as a new algorithm for a concept of a relational set being a set of new fault events and that relates occurred events to the relational set at a high speed so as to increase the speed of a correlation processing section especially. SOLUTION: The system is made up of three layers, that is, a lowest event handling layer receiving plural fault alarms from a network element, a middle correlation layer locating a fault location through the relation between the fault alarms received from the handling layer, and an uppermost intelligent layer locating a cause to the fault based on the result from the correlation layer. The correlation layer defines a set of fault alarms caused in relation from a fault as a relational set in advance and finishes relation of all fault alarms belonging to any relational set so as to locate a fault location.
