IESG Note

   This memo documents a way of tunneling Ethernet frames over MAPOS
   networks.  This document is NOT the product of an IETF working group
   nor is it a standards track document.  It has not necessarily
   benefited from the widespread and in-depth community review that
   standards track documents receive.

Abstract

   This memo describes a method for forwarding media access control
   (MAC) frames over Multiple Access Protocol over Synchronous Optical
   Network/Synchronous Digital Hierarchy (MAPOS), thus providing a way
   to unify MAPOS network environment and MAC-based Local Area Network
   (LAN) environment.

1. Network Model

   In the Network model assumed in this memo, MAC-based LAN traffic is
   forwarded by a MAPOS switched network.  This model allows distant
   LANs to be interconnected to form a single LAN segment.  Transparent
   LAN Service (TLS) is provided by encapsulating MAC frames in MAPOS
   frames and by mapping MAC addresses to MAPOS addresses.
