Just as there are several configurations in the building, there are several levels of bandwidth sharing between the building and the router. A dedicated 100 Mbps Fast Ethernet connection may be provided for the current standard building configuration only. To this point we have described the network topology, network devices, and network configurations. Now we address the protocols and applications that the NCState. Net backbone supports.
Net backbone provides for a multiprotocol, routed environment.
The legacy network supports building connectivity at 10 Mbps and provides for routing of IPX and Appletalk traffic. Note that the interface support and application support is for technologies which have reached the end of their development cycles. IP Intranet Figure 3. Buildings in the vicinity of a communications hub gain access to the backbone through the router in that location. In addition to traditional IP routing, the NCState.
