Apparatus and method to establish a connection between apparatuses while synchronization of connection information thereof is suspended

A method performed by a first computer, the method comprising:

• providing the first computer with a memory that stores first connection information in association with each of connections established between the first computer and a second computer;
• synchronizing the first connection information stored in the memory with second connection information that is managed by the second computer;
• when a connection is to be established between the first computer and the second computer while synchronization of the first connection information performed by the first computer is suspended, generating first unique information that is unique at least between the first computer and the second computer, and transmitting the generated first unique information to the second computer;
• and
• establishing, based on the first unique information, a connection between the first computer and the second computer.

A non-transitory, computer-readable recording medium having stored therein a program for causing a first computer to execute a process comprising:

• providing the first computer with a memory that stores first connection information in association with each of connections established between the first computer and a second computer;
• synchronizing the first connection information stored in the memory with second connection information that is managed by the second computer;
• when a connection is to be established between the first computer and the second computer while synchronization of the first connection information performed by the first computer is suspended, generating first unique information that is unique at least between the first computer and the second computer, and transmitting the generated first unique information to the second computer;
• and
• establishing, based on the first unique information, a connection between the first computer and the second computer.

A system comprising:

• a first apparatus including a memory and a first processor coupled to the memory;
• and
• a second apparatus including a second processor, wherein
• the memory is configured to store first connection information in association with each of connections established between the first apparatus and a second apparatus;
• the first processor is configured to:
• synchronize the first connection information stored in the memory with second connection information that is managed by the second apparatus, and
• when a connection is to be established between the first apparatus and the second apparatus while synchronization of the first connection information performed by the processor is suspended, generate first unique information that is unique at least between the first apparatus and the second apparatus, and
• transmit the generated first unique information to the second apparatus;
• and
• the first processor of the first apparatus and the second processor of the second apparatus are configured to establish, based on the first unique information, a connection between the first apparatus and the second apparatus.
