Multiprotocol Encapsulation over ATM
Multiprotocol Encapsulation over ATM is defined by the specification RFC 2684. Through the use of ATM Adaptation Layer 5 and Logical Link Control (LLC) Subnetwork Access Protocol (SNAP), multiple protocols can be differentiated inside of ATM Cells.
The Abstract of RFC 2684 reads:
"This memo replaces RFC 1483. It describes two encapsulations methods for carrying network interconnect traffic over AAL type 5 over ATM. The first method allows multiplexing of multiple protocols over a single ATM virtual connection whereas the second method assumes that each protocol is carried over a separate ATM virtual connection."
