26 The Practical OPNET User Guide for Computer Network Simulation
• ppp_server and ethernet_server are used to model servers, which are also
end nodes, but they provide services for various client applications over
SLIP and Ethernet links respectively. Server and workstation objects allow
modeling of the client–server paradigm.
• 1000BaseX_LAN, 100BaseT_ LAN, and 10BaseT_ LAN models are used
to simulate Ethernet LANs that run over 1000BASE-X, 100BASE-T, and
10BASE-T Ethernet connections respectively. By default, each of the above
network models simulates the operation of a LAN with 10 end nodes.
