RFC 2684 obseletes RFC 1483

RFC 2684 is the specification defining Multiprotocol Encapsulation over ATM Adaptation Layer 5. Through the use of LLC encapsulation, 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."
