PROBLEM TO BE SOLVED: To provide a connection method for an accumulation node, which can efficiently execute a connection processing to the accumulation node even if a change exists in the accumulation node storing accumulation data. SOLUTION: For connecting an exchange 2 to the corresponding accumulation node as accumulation service to users A and B, the exchange 2 is connected to an exchange 3 in accordance with connection information which is previously decided. The exchange 3 is connected to a first accumulation node 51 in accordance with connection information which is similarly and previously decided. The correspondence of the user and the accumulation node is stored in the accumulation node 51 and accumulation data of the user A is stored in the first accumulation node 51. Thus, the processing of service to the user A is executed in the first accumulation node 51 and the user B is stored in a second accumulation node 61. Thus, the user is connected to the second accumulation node 61 through LAN. |
