摘要： PROBLEM TO BE SOLVED: To suppress an increase of communication traffic, and in addition to reduce cache memory capacity and a search processing load in an SIP application server.SOLUTION: When a presence request is received and if a corresponding dialogue does not exist, a presence information distribution device obtains presence information of a corresponding user A from a presence server 3 and transfers it to a request source client device CT and also obtains the friend list of the user A from an SNS server 4. The presence information distribution device extracts the number of friends N from the friend list, compares this number of friends N of the user A with the minimum number of friends Nmin of other users already cached in a cache memory 40, and if N≥Nmin, makes the cache memory 40 store the cache information of the user A instead of the cache information of a user having the minimum number of friends Nmin stored in the cache memory 40, and opens an SIP dialogue of the user having the minimum number of friends Nmin.

摘要： PROBLEM TO BE SOLVED: To avoid the non-convergence of retrieval times because IFs of an adjacent switch to be opposite in linking-up retrieval processing of each switch are not found indefinitely.
SOLUTION: Switches 10 (10A and 10B) determine the transmission time of a signal for linking-up retrieval on the basis of respective device IDs of the switches 10. When the switches 10 select an IF in which linking-up retrieval processing is performed, the switches 10 continuously transmit the signal for linking-up retrieval about the IF for the determined transmission time. When a signal from an adjacent switch cannot be received by the IF, another IF is selected, and the signal for linking-up retrieval is continuously transmitted for the transmission time. When the signal from the adjacent switch is received here, that is, when the linking-up is successful, information of the IF is recorded in interface information. Such processing is executed until linking-up of all IFs is successful.

摘要： PROBLEM TO BE SOLVED: To eliminate the need of performing the processing of a header corresponding to each service housed inside a multi-domain network by the boundary node of each domain. SOLUTION: The termination node 1 sets a universal layer 102 across all the domains 10 inside the multi-domain network 100. Then, the header of the universal layer 102 is added to the header of the service layer 101 of data to be transferred and the header of the service layer 101 is encapsulated. Further, the termination node 1 adds the header of a transport layer 103 and performs transfer. The boundary node 2 eliminates the header of the transport layer 103, changes the header of the universal layer 102, and thus transfers the data to the boundary node 2 of another domain 10.

摘要： PROBLEM TO BE SOLVED: To specify a link having a high possibility of the occurrence of congestion when a plurality of IP links become uncommunicable. SOLUTION: A congestion influence degree evaluation apparatus 10 uses network setting information and fault position information indicative of a fault pattern to create route information 134 indicative of a detour route in the case that a fault of the fault pattern occurs on a network. Next, based on the detour route and alternating traffic information in the network, the traffic volume information 135 of each link in the network is obtained for each fault pattern. The presence/absence of a congestion occurrence link from a result of simulation and a degree of congestion are outputted as a congestion influence degree evaluation result when there is the congestion occurrence link.

摘要： PROBLEM TO BE SOLVED: To provide a technique for reducing a reject rate of reservation by sharing an unused empty band in path bands for effective use, and by preventing the band from being occupied. SOLUTION: A service band BWa, namely the band of service A, and a service band BWb, namely the band of service B, are allocated to the band of the path in advance. Then, a band allocation device 10 calculates an empty band Wv for the service A, when receiving the reservation of the band by the service B at time t0. The empty band Wv is calculated by subtracting the maximum allocated band Wat (the maximum value of the total of reservation allocation bands between time t1-t2) from the service band BWa. As shown in Fig.10, when time and band directions are set to be X, Y axes, respectively, a straight line passing through a point (X, Y)=(t0, Wv) and a point (X, Y)=(t3, 0), namely an empty band allocation function X(t), is applied to set a value X(t2) to be a rental band Wxb.

摘要： PROBLEM TO BE SOLVED: To reduce time for BGP simulations. SOLUTION: A simulator 10 acquires a BGP attribute value to be configured for routing information which is advertized by a sponsor router of the routing information in an IP network 1 based on BGP filter information. Then, the simulator 10 determines to which router 2 the routing information advertized by the sponsor router is transmitted based on topology information in the IP network 1. If there is possibility that the router 2 receives routing information, the address of which is the same, at a plurality of times, the simulator 10 simulates which route is to be selected as the optimum route based on the BGP attribute value added to the routing information.
