One way OIT Network Systems monitors the campus data nework is by collecting statistics. Many of the statistics measure traffic volume flowing through the network infrastructure. In some cases, we collect other relevant data; for example, modems in-use, or CPU usage of key infrastructural components. We also collect some statistics provided by a few hosts attached to the network.

Campus Core and Border Switches Traffic Statistics

These switches comprise the core (and Internet/Internet2 border) of the campus network. Some of these switches are the Layer 2 presences of switch/routers whose Layer 3 presences appear in the router document below.

Router Traffic Statistics

Traffic volume passing through OIT's core and Internet/Internet2 border routers. Also selected statistics for some departmental routers. Some of these routers are the Layer 3 presences of the switch/routers whose Layer 2 presences appear above.

Campus Aggregation Switch Traffic Statistics

Traffic volume passing through building aggregation switches and building point of entry switches.

Remote Access Traffic Statistics

These include selected Remote Access connections to the campus network, including OIT's VPN service, some DSL-attached sites, and OIT's dial-in services. Modem usage for the latter is also available.

Server Traffic Statistics

Includes selected hosts, typically OIT hosts that function as servers for a variety of major campus services.
