Configuring ATM

Four implementation methods are used to transmit information over ATM. Briefly, they are as follows:

  • RFC 2684, “Multiprotocol Encapsulation over AAL5 (ATM Adaptation Layer 5)”— A manual method of mapping upper-layer protocol addresses to the ATM addresses. Updates RFC 1483.

  • RFC 2225, “Classical IP and ARP over ATM”— A dynamic method of transporting IP over ATM without the need for manual mapping. Updates RFCs 1577 and 1626.

  • Local-Area Network Emulation (LANE)— Mimics LAN behavior over ATM cloud.

  • Multiprotocol over ATM (MPOA)— A dynamic method, based on LANE, of transporting all protocols, not just IP.

For the purposes of the exam, this book concentrates on multiprotocol encapsulation over AAL5 and Classical IP and Address Resolution ...
