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.

� � 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].
