2 A S I A P A C I F I C N E T W O R K I N F O R M A T I O N C E N T R E Addressing Plan  To complete documentation  First need a technical PLAN  Documenting the architecture of the present and eventual goal  IP addressing is fundamental part of network design  IP addressing ‘planning’ example to follow..

3 A S I A P A C I F I C N E T W O R K I N F O R M A T I O N C E N T R E Some Icons Router (layer 3, IP datagram forwarding) Network Access Server (layer 3, IP datagram forwarding ) Ethernet switch (layer 2, packet forwarding)

4 A S I A P A C I F I C N E T W O R K I N F O R M A T I O N C E N T R E Addressing Plan  Identify components of network  Customer services  ISP internal infrastructure  Identify phases of deployment  Starting off, 6 months, 12 months  Identify equipment and topology changes  Need for redundancy  Need for increased scale

5 A S I A P A C I F I C N E T W O R K I N F O R M A T I O N C E N T R E Network Plan  Starting off ’ Leased line services 5-8 customers Dialup services 16 modems Interconnected resilience Upstream ISP 15 hosts NOC operations 10 hosts Internal DNS,Web Mail servers ISP Infrastructure Customer services 5 hosts Virtual web (name based)
