Wide Area Network, external network connectivity beyond the NCAR/UCAR campuses
MAN
Metropolitan Area Network, network connectivity between local NCAR/UCAR campuses and local organizations such as NOAA, NIST, the City of Boulder, and the University of Colorado
LAN
Local Area Network, local network connectivity within and between buildings within a NCAR/UCAR campus
NCAR/UCAR Campuses

  • MFS - Marshall building and field experiment areas
FRGP
Front Range GigaPoP, a consortium of Universities, non-profit corporations, and government agencies that cooperate in an aggregation point called the FRGP in order to share Wide Area Networking (WAN) services, access to the commodity Internet, access to the Abilene (I2) research network, and access to the National LambdaRail (NLR). The current members are listed on the FRGP Members page. The FRGP is one of several gigapops in the US. GigaPoP members typically enjoy reduced costs, shared expertise, shared services, increased buying power, and economies of scale. UCAR provides the engineering and Network Operations Center support for the FRGP.
IPT
Internet Protocol Telephony, telephone service provided over network cabling and devices.
COC
CISL Operations Center
UPoP - UCAR Point of Presense

3. Availability

Provided higher level facility and service dependencies are available, the service is designed to be highly available, with the exception of scheduled maintenance and testing, unanticipated hardware or software failure, and funding constraints.  

Maintenance Windows

Whenever possible, changes to the network and telecommunication services will be made within the following specific off-hour time windows. Non-service effecting modifications and testing may be performed at anytime throughout the business day, at the discretion of the Provider engineers. See the NETS Outage Notification Policy for details. For IPT problems, refer to the IPT Outage Notification Procedures for details.

4. Service Request/ Reporting

Business Hours: 08:00 - 17:00

Request System: Work Request

CISL Operations Center (Urgent): 303-497-1200 or COC@ucar.edu

Two methods are available to submit network and telecommunication service requests:

  1. Work Request - The NETS work request system can be used to submit regular and urgent work requests. If a request is marked as URGENT an engineer or technician will be paged.
  2. Urgent/Outage, x1200, 303-497-1200 - The CISL Operations Center (COC) is available 7/24/365. The COC should be contacted to report an outage or to receive outage status or if an outage prevents submitting a work request. The phone will be answered promptly, usually by a COC operator. During late-night shifts, there is only one COC operator. The operator takes short breaks, during which the phone will be answered by a secondary staff person. Should this happen, the primary COC operator will be contacted immediately and will call the reporting number back within 10 minutes.

Problem Status

Once notified that a UCARnet problem exists, the Provider engineer will send the following notifications:
  1. An email via the Maintenance/Outage Notification Form to inform all relevant users that the NETS engineer is aware of the problem, a summary of the problem, and that work has started on the problem.
  2. Timely email messages to the same list when significant changes in the status of the problem occur.
  3. When the problem is solved, an email to the same list explaining the resolution of the problem.
In these emails, time-stamps will be used to define when significant events took place.

Some UCARnet problems may prevent delivery of email messages to users. In such cases, users can call the COC at 303-497-1200 to receive status information. The Provider engineer will keep the COC informed of the status of outstanding problems.

The Provider will make available to the users an on-line archive of email messages relating to reported problems, status, and analysis. NETS Outage Mailing List Archive.

Escalation Procedures

At a minimum, when a problem has not been resolved within an hour, a second Provider engineer will be called to help with the problem. This policy will be waived if a problem is out of the UCAR's hands. For instance, if a major link to an Internet Service Provider (ISP) is down due to problems in the ISP's network infrastructure.

5. Monitoring

The Provider COC will, at a minimum, monitor the UCARnet, Front Range GigaPop (FRGP), UPoP equipment which includes all LAN, MAN, and WAN connectivity. Additional monitoring will be added as needed. When the COC detects problems with the UCARnet equipment a Provider engineer will be notified. When the COC detects problems at the User end of a link, after confirming that all UCARnet equipment is operational, the responsibility of the COC staff as well as their ability to fix a problem is limited. The COC staff will make an attempt to notify a User designated contact person. At most, the Provider COC staff will telephone a limited set of Primary-institutionally provided telephone contact numbers in an attempt to reach a User. Instructions for contacting User personnel will be maintained in password-protected web pages on the UCAR web site so that Provider and COC staff can easily inspect and maintain the instructions.
