Abstract
A Point-to-point protocol configured to provide communication exchange between a first device and a second device. The point-to-point protocol is configured to negotiate an exchange rate and establish a connection for the communication exchange between the first and second device. As system dynamics change, the point-to-point protocol is also configured to permit application programs in the first device and the second device to request renegotiation of the exchange rate at any time. The point-to-point protocol is also configured to provide confirmation to a sending application program that information was delivered to a receiving application program.
Claims39
A method for communicating between devices, the method comprising:
- sending a first synchronization request message from a first device to a second device, the first synchronization message including a first exchange rate;
- receiving a first synchronization acknowledgement message in the first device, the first synchronization acknowledgement message including one of the first exchange rate and a second exchange rate as a negotiated exchange rate;
- responsive to the negotiated exchange rate, establishing a connection between the first device and the second device;
- and
- responsive to establishing the connection, sending communications to the second device over the connection at the negotiated exchange rate.
A machine readable medium having stored thereon machine readable instructions, the instructions comprising:
- first instructions operational when executed on a first device to send a first synchronization request message to a second device, the first synchronization message including a first exchange rate, and to receive a first synchronization acknowledgement message, the first synchronization acknowledgement message including one of the first exchange rate and a second exchange rate as a negotiated exchange rate;
- and wherein
- the first instructions are further operational to cooperate in establishing a connection between the first device and the second device, and to send communications to the second device over the connection at the negotiated exchange rate.
A point-to-point communication apparatus, comprising:
- a first device adapted for sending to a second device a first synchronization request message including a first exchange rate, receiving a first synchronization acknowledgement message generated in response to the first synchronization request, the first synchronization acknowledgement including as a negotiated exchange rate one of the first exchange rate and a second exchange rate, establishing a connection with the second device, and for sending to the second device communications at the negotiated exchange rate.
A computer-readable data signal encoded on a medium of transmission, the data signal comprising:
- a first synchronization acknowledgement message generated by a first device in response to reception of a first synchronization request message including a first exchange rate, the first synchronization acknowledgement message including one of the first exchange rate and a second exchange rate as a negotiated exchange rate.
