Initial Assessment: The current district network connectivity for all district and college sites is provided by leased dark fiber optics owned by a variety of network providers (including Sacramento Regional Transit, the City of Sacramento, and the Sacramento Municipal Utilities District). The network lacks the necessary redundancy and service level agreements to avoid exposure to extended service disruption and does not have the necessary bandwidth to adequately support current network needs and anticipated future use needs.  Network outages and network congestion affect the student experience.  Recent 10 Gbps network connectivity improvements to district data centers have mitigated some network congestion but have not improved college network connectivity at the district’s three largest colleges.  Bandwidth limitations, network transparency and visibility, and network redundancy and fault tolerance were the top three network connectivity concerns expressed by college IT staff [Refs 3, 4, and 5]. 

Plans:

  1. Working with the California Community Colleges Chancellor’s Office and the Corporation for Education Networking Initiatives in California (CENIC), complete the district’s primary 10 Gbps network ring by fall 2019.
    1.  Lead(s): DOIT Technical Services
    2.  Funding Sources: California Community Colleges Chancellor’s Office for installation and ongoing costs
    3.  College and District Roles: DOIT will provide project oversight, including providing college IT staff with expected installation timelines at their sites.  College IT will collaborate with DOIT to make facilities available for service installation.  
  2. Working with the approved vendor, Comcast, install the district’s secondary network.  Complete network installation by fall 2018.
    1.  Lead(s): DOIT Technical Services
    2.  Funding Sources: Program Development Funds (one-time and on-going operational)
    3.  College and District Roles: DOIT will provide project oversight, including providing college IT staff with expected installation timelines at their sites.  College IT will collaborate with DOIT to make facilities available for service installation. 

Indicators of Success:

  1.  Each college will have at least one 10Gbps primary network connection and a backup network connection with at least one 1Gbps throughput.
  2.  Each of the 20 identified LRCCD sites will have at least one 1Gbps primary network connection.
  3.  Networks will be assessed annually to ensure:
    1.  Network connectivity uptime is measured monthly and maintained at or above LRCCD network uptime targets (99.9%).
    2.  Network bandwidth saturation remains below 75% at each college and instructional center as measured on an average hourly basis.
    3.  Successful network failover tests at each district network location with primary and secondary connectivity.
Report on network activity and bandwidth utilization by class-of-service (COS) and quality-of-service (QoS) category/designation on each network and at each network location.
