Readers are encouraged to review the ATM Forum and ITU-TS (formerly CCITT) references for more detailed information about ATM implementation agreements and standards.Acknowledgments This memo could not have come into being without the critical review from Jim Forster of Cisco Systems, Drew Perkins of FORE Systems, and Bryan Lyles, Steve Deering, and Berry Kercheval of XEROX PARC.
This layer is responsible for reliable data transmission between nodes.
Each layer and sublayer is described in more detail in the following sections.
The physical layer provides for the transmission and reception of ATM cells across a physical medium between two ATM devices; this can be a transmission between an ATM endpoint and an ATM switch, or it can be between two ATM switches.
The method includes designating a variable bit rate ATM Adaptation Layer (AAL) protocol to define ATM cell traffic flow from the source to the destination.
A synchronous residual timestamp (SRTS) value indicative of the timing of a source clocking function is encoded and transmitted with an ATM cell using a variable bit rate AAL, such as AAL2 or AAL5.
