Stitching it all Together

     - roll out
      - shipping
      - end site training / interaction

The next area to examine is the actual roll out of the network services. If this has been well coordinated this phase should be relatively rapid. The major piece of advice is to understand the environment where each routing unit is to be deployed, and pre-configure the unit to match this. In this way the units can be shipped pre-configured, and deployment is then a matter of interconnecting the various LAN and WAN interface cables.

In terms of end site interaction there are two interaction mechanisms:

The first is where the site is hosting equipment operated by the service provider, in which case the issue here is one of ensuring that the end site is aware of its responsibility to ensure that the unit is housed within an appropriate environment, and access is available to service personnel at agreed time windows.

The second interaction with the client site is a larger area of interaction, and is effectively the split of responsibility between service provider and client for components of the IP infrastructure and the associated service definition support. issue of the interaction of routing environments has been covered in some detail in the sections above, and will not be reiterated here. However there are a number of others of responsibility including:

• DNS (name and address bindings)
• Mail configurations (and the related DNS configurations and the interaction with the directory service)
• Security (encryption, firewalls, authentication, access management, socket redirectors, etc)
• information services (including whois, finger, X.500, netfind, and other related directory services
• Network Time (ntp)
• Usenet flows
• Multicast networking services
• Information service configurations (ftp. gopher, WAIS, WWW, etc)
• Wide Area file system configuration
