IPC: H04L12/28
Filed: 1995-04-26
Abstract: PURPOSE: To facilitate multicast type data communication processing. CONSTITUTION: When mutually exchanging the same data between the plural processes operated on plural computers 11 and 12, multicast communication objects 41, 42 and 43 having the same name (object name) are previously generated on respective processes 31, 32 and 33. The procedure of data exchange is performed by issuing the request of transmission/reception to these multicast communication objects 41, 42 and 43. When the data transmission request is received from the process 32, for example, the multicast communication object 42 requests processing to a multicast communication managing server 3. Then, the multicast communication managing server 3 transmits the data to the processes 31 and 33 owning the multicast communication objects 41 and 43 to be objects.  Concerning the reception of data, it is also performed by issuing the reception requests from the processes 31 and 33 to the multicast communication objects 41 and 43.
