Abstract
When, in communication using a protocol in which at least two streams are established over a connection, a notification that a new stream will be reserved is made, a process for preventing a non-communication state exceeding a predetermined amount of time is initiated and a frame is sent at least every predetermined amount of time in the case where there is no other stream currently reserved, whereas processing is ended without initiating the stated process in the case where there is already a reserved stream.
