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.

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.

RFC 3422            Forwarding MAC Frames over MAPOS       November 2002

   This network model is shown in figure 1. "MAPOS network" is composed

   of MAPOS switches, SONET/SDH leased lines and optical fiber cables.

   A LAN is connected to a MAPOS network by a Network Adapter (NA) which

   has a MAPOS interface and an ethernet interface.  A unique MAPOS

   address is assigned to each NA by NSP (Node-Switch Protocol) [2].
