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