The most desirable situation is achieved when the NMC establishes a high speed link (64 kbps) with the next hop RTH, preferable outside the RA I region and acquires its own block of IP addresses and so becomes a pseudo ISP on its own right. RTH Nairobi is one, with IP address 195.220.202.z. The "z" octet has been sub-netted and some of the sub-nets allocated to NMCs which are linked to it

• SERVERS: Internet - PC type (c)

• Web + meal PC type (d)
• FTP + PrinterPC type (f)
• Dial upPC type (c)

• Firewall
• Printers: Various Matrix, Laser, Colour
• Router
• Modem
• LAN accessories
• Link to ISP

Many of the server software implementations are likely to be bundled together. For example, WIN NT/WIN 2000 Server Network Operating System come bundled with all the above server options; all you have to do is to configure them on the PC. Otherwise, the two most important software in the server group are:

• The (network ) Operating System - Windows 95, Win NT, Win 2000, Novel Net ware, Solaris, Irix, Sun OS, etc.
• The Web Server Software (Browser) - Microsoft Internet Information Server (MIIS), Netscape Enterprise Server, NetWare Web Server, etc.

• It should always be remembered that there are ALWAYS two versions of the server programs. One version is for the host and the other version is for the client.

• To establish a connection between the GTS and the Internet requires mandatory security considerations. Various types of firewalling: filtering, encryption, proxy servers, etc., need to be implemented.

The Internet LAN can remain segregated from and independent of the AMSS LAN. When appropriate security measures have firmly been put in place (e.g. installation of "catapult " proxy server and/or Protocol Isolation with Server Replication Server) the Internet LAN can then be connected to the Operational Application LAN to end up with a configuration shown at Annex 3.
