Case 10:   No Intranet Accessing campuses through Other ISP
(see drawing, below)

Listing of Cases

In this case, SUNYNet does not deliver any major network services to the campus.

Method of delivering Internet and intranet:
In this case, the campus and its application users have determined that the general Internet will suffice for all of its SUNY-to-SUNY communications. This determination might be based on the campus's having no intranet applications, or none that require encryption, tunneling, or prioritization. Since the campus does not use AT&T, it will have more hops and some potentially serious points of congestion between the two core networks of the ISPs when communicating with the other campuses that use AT&T exclusively. Before choosing this arrangement, this campus has determined that their Internet connection has sufficient bandwidth to accommodate its time-sensitive applications and that traffic between the two ISPs does not usually get congested.

Roles of the Routers:
IP traffic that is bound for off-campus destinations gets directed to the ISP (orange, cross-shaped box) router which sends it into its core network (globe). The network delivers it directly to any other SUNY campuses using the same ISP. For the SUNY sites using AT&T, data flows through peering arrangements between the campus's ISP and AT&T.

All of the public IP address space for the campus are announced to the Internet by the campus's ISP.
