Wired Networks

Colby's wired network infrastructure includes all network ports/wall jacks, the electronic switches and routers that they connect to as well as the physical copper and fiber optic cables interconnecting them. If you have a technical issue with a network jack or port, please contact the appropriate helpdesk for assistance and they will relay the issue to network services if necessary.

Network Core

The Colby network core, or backbone, currently consists of four routers and two edge routers redundantly interconnected by 10-Gigabit Ethernet over fiber.  Traffic filtering (by application and protocol) is performed at the network edge for bandwidth efficiency.

Internet access is provided through independent provider connections.  Current Internet traffic information on can be found here.

Academic and Administrative Buildings

All Academic and Administrative buildings on campus offer 100 and 1000 Mbps (1Gbps) Ethernet connections with Gigabit Ethernet uplinks to the core.  Ports are available in all offices, classrooms, labs and in some public areas.  Most academic and administrative buildings have been upgraded to gigabit (1000 Mbps) Ethernet.

Residence Halls

Residence halls are networked with 100Mbps Ethernet with Gigabit Ethernet uplinks to the core.  There is a network port for each student in her/his room and additional ports are provided for connecting notebook computers in many lounges and in the libraries and classrooms.  Students are required to provide their own Ethernet network cable for residential connections.

All wired and wireless network connections in the residence halls are under the control of the Network Access Control (NAC) system, which requires a valid Colby account and system validation prior to gaining access to the network.

General instructions on connecting to the wired network can be found at ITS Support and Services.
