Abstract
Multiple Access Protocol over SONET/SDH (MAPOS) is a high-speed
link-layer protocol that provides multiple access capability over a
Synchronous Optical NETwork/Synchronous Digital Hierarchy
(SONET/SDH).
This document specifies the frame format for encapsulating an IPv6
datagram in a MAPOS frame. It also specifies the method of forming
IPv6 interface identifiers, the method of detecting duplicate
addresses, and the format of the Source/Target Link-layer Addresses
option field used in IPv6 Neighbor Discovery messages.

1. Introduction
Multiple Access Protocol over SONET/SDH (MAPOS) [1][2] is a high-
speed link-layer protocol that provides multiple access capability
over SONET/SDH. Its frame format is based on the HDLC-like (High
Level Data Link Control) framing [3] for PPP. A component called a
"Frame Switch" [1] allows multiple nodes (hosts and routers) to be
connected together in a star topology to form a LAN. Using long-haul
SONET/SDH links, the nodes on such a "SONET-LAN" can span a wide
geographical area.
This document specifies the frame format for encapsulating an
Internet Protocol version 6 (IPv6) [4] datagram in a MAPOS frame, the
method of forming IPv6 interface identifiers, the method of detecting
duplicate addresses, and the format of the Source/Target Link-layer
Addresses option field used in Neighbor Discovery messages such as
Router Solicitation, Router Advertisement, Neighbor Solicitation,
Neighbor Advertisement, and Redirect messages.
In the remainder of this document, the term "MAPOS" is used unless
the distinction between MAPOS version 1 [1] and MAPOS 16 [2] is
required.
