|SUBJECT:||Network Improvements Coming this Summer|
In the coming months, the Office of Information Technology (formerly Information Technology Services) will make two network improvements that will have both immediate and long-term benefits for users of the campus networks.
The more immediate performance improvement will come as a result of upgrading the primary campus Internet connection from 1 to 10 gigabits per second (Gbps). Near the end of this past spring semester this Internet pipeline became saturated during very high-traffic peaks, which resulted in infrequently degraded network service. The upgrade of this connection, scheduled for completion before the end of June, will eliminate saturation of that link. This change eliminates congestion for traffic that uses the Front Range GigaPOP (FRGP) which is located in Denver. The FRGP provides much of our access to the commodity Internet (also known as I1) and our access to the various national research networks including Internet2/Abilene (I2), National LambdaRail (NLR), and the Energy Sciences Network (ESNet).
During July and August the Office of Information Technology will upgrade the backbone equipment that supports the campus network which currently provides 10 gigabit per second bandwidth. This infrastructure improvement paves the way for higher networking speeds in the future including a 40 or 100 Gbps backbone. In addition, this change facilitates the use of more Quality of Service (QoS) features that will support services such as media streaming for courses, voice over the data network, and video and web conferencing for faculty, students and staff.
In order to complete the backbone equipment update there will be a series of localized network outages in the early morning hours, typically on Tuesdays, Wednesdays and Fridays, that should be completed by 6:30 a.m. each morning. These outages will last approximately 60 minutes and a minimum of two weeks’ notice will be provided per location. OIT will work with your departmental Computer Support Representative (CSR) to schedule and communicate outages in your building and make sure that they are sensitive to early morning activities or special events in your building. You can learn who your CSR is at http://oit.colorado.edu/support-training/csr-lookup.
Questions about either of these network improvements should be directed to OIT Associate Director of Network Engineering & Operations Ray Baum at firstname.lastname@example.org or 303-735-4331. If you have general questions about the campus network or networking services, please contact the IT Service Center at email@example.com or 303-735-4357 (5-HELP from a campus phone). Phone help is available Monday through Friday, 8 am to 7 pm.
We thank you for your patience while these network improvements are put into place.
