Abstract:
1. A method for initializing a communication link for transmitting a data stream from a first computer through a synchronous optical communication network to a second computer, comprising: transmitting a first request message at a first time from the first computer to a first GFP data mapping device; generating a first GFP data frame based on the first request message using the first GFP data mapping device that indicates that the communication link is being requested, and transmitting the first GFP data frame through the synchronous optical communication network to a second GFP demapping device; decoding the first GFP data frame to obtain the first request message and transmitting the first request message from the second GFP demapping device to the second computer; generating a second acknowledgement message using the second computer in response to the first request message and transmitting the first request message to a third GFP data mapping device; generating a second GFP data frame based on the second acknowledgement message using the third GFP data mapping device and transmitting the second GFP data frame through the synchronous optical communication network to a fourth GFP demapping device; decoding the second GFP data frame at a second time using the fourth GFP demapping device to obtain the second acknowledgement message; and initializing the communication link between the first computer and the second computer in response to the acknowledgement message.
