It defines two mechanisms for identifying the protocol carried in ATM Adaptation Layer 5 (AAL5) frames.
Multiprotocol Label Switching | Micro-encapsulation | ATM Adaptation Layer 5 | Unidirectional Lightweight Encapsulation | Multiprotocol Encapsulation over ATM | Molecular encapsulation | encapsulation | Cell encapsulation | ATM Forum | ATM card |
Virtual circuit multiplexing or VC-MUX is one of the two (the other being LLC encapsulation) mechanisms for identifying the protocol carried in ATM Adaptation Layer 5 (AAL5) frames specified by RFC 2684, Multiprotocol Encapsulation over ATM.
