Next Generatiox� Network Plazi Page 3 � Facilitate interoperable communications between the NSCC cities and other jurisdictions throughoutthe region � n 1.2 Summaryof Recommendations The major recommendations offered by this Report include: �.�.1 Build a Fiber Network to Meet the Ci#ies' interr�a� Communications Needs The NSCC cities should continue and expand their successful practice of operating fiber resources for their own internal use. The cities have already demonstrated significant success with this approach and currently operate a highly-functional and efficient Institutional Network (I-Net), much of which was constructed by the cable company. We reco�end. that the cities deploy fiber optics extensively in order to meet their growing communications needs and future proof their e�sting network Based on our assessment of the NSCC members' and other agencies' needs, we anticipate extensive use of this fiber network lry first responders, schools, county, and other government departments. The cities require more capacity and connectivity to more Iocations—and these requirements are likely to grow dramatically in coming years. The proposed network is therefore designed to enable high bandwidth and cost-effective scalability to even higher transmission rates. The purpose is to design based on future needs--solutions based solely on today's uses will experience early obsolescence. 1.2.1.1 Recommended Fiber Architecture: Star Topology Specifically, we recommend that the NSCC upgrade and supplement (and eventually replace) the existing I-Net with fiber optics independent of Comcast's infrastructure. Additional fiber connectivity provides increased bandwidth, redundancy, and scalability compared to other approaches and mitigates the risks associated with reliance on future cable franchise agreement negotiations. CTC recommends a design that r,�iiTOrs the current star topology of the I-Net, migrates the I-Net from the Comcast plant, and provides a backbone ring topology for additional redundancy. The recommended design envisions that the major networking facilities for each network site (such as City Halls) are served directly from the backbone ring. This provides ring redundancy to the key sites and facilitates connectivity to the other iocatian{s}. From each core site, access sites are connected to the nearest core site to provide connectivity into t�.� NSCC network Core sites act as link aggregators and minimize the construction of fiber necessary to provide connectivity to each member facility. all text and diagrams p CTC 2007
