CHAPTER 1: INTRODUCTION
The Routing Services software provides the following additional
funtionality:
• Security via access lists
• Directed User Datagram Protocol (UDP) broadcast forwarding

With the Router Software loaded in the EMME, the EMME has the
options available for three network protocols. The user, through Local
Management, can select either IP, IPX, or DECnet Phase IV routing.
IP routing is the TCP/IP protocol that specifies how information is broken
into packets, and how they are addressed to route over a network.
DECnet Phase IV specifies two forms of DECnet routing as follows:
• Phase IV or Level 1- For routing DECnet packets from one node to
another within a DECnet area.
• Area or Level 2 - For routing DECnet packets from one DECnet area
to another.
The DECnet Phase IV routing services are based on Digital Equipment
Corporation's requirements for DECnet Phase IV, Level 1, and Area
routers.
