Next Gencrati,on Network Plan Pacre 3 Z> Facilitate iMeroperable coi-m-nunications between the NSCC cities and other jurisdictions throughout thf,:, recrIOT1 1.2 Summary of Recommendations The major reconunendations offered by this Report include- 1.2.1 Build a Fiber Network to Meet the Cities' Internal Communications Needs The NSCC cities should continue and expand, their successful practice of operating, fiber resources for their own intemal use. The cities have already, demonstrated significant success with this approach and currently operate a highly-functional and efficient Institutional Network (I-het), inuch of which was constructed by the cable company. We recommend that the cities deploy fiber optics extensively in order to meet their growing co=unications needs and future proof their existing network. Biased on, our assessment of the NSCC members' and other agencies 11 needs we anticipate extensive use of this fiber network by first responders, school's, county, and other govemment departments. The cities require more capacity and con,nectivity to more locations—and these requirements are likely to brow dramatically in coming years. The proposed. network iis therefore designed to enable high bandwidth and cost - effective scialability to even hiligher transmission rates. The purpose, is to design biaseld on future needs—solutions used solely on today's uses will experience early obsoliescieDice, 1.2.1.1 Recommended Fiber Architecture: Star Topology Specifically, we recommend that the NS CC upgrade and supplement (and eventually replace) the existing I-Net with -fiber optics 'Independent of Comicast"i 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 negotiatio-ns. CTC recoTm-nends a design that milTors the current star topology of the I-Net, mi'grates the I-Net from the C mcast plaint, and provides a backbone ring t'op'ology for additional redundancy. The, reconu-nended design envisions that the ma j, , or networking facilities, for each network site (such as City Halls) are served directly from thebackbione, ring. This provides riiig redundancy to the key sites and facilitates connectivity to the other, location(s). From eacb core site, access sites are, connected to the Dearest core site to provide connectivity into t4o,, NSCC network, Core sites act ais link aggregators and provi - I minimize the construction of fiber necessary, to provide connectivity to each member facility. �ill text iainid, diiiiagrams Pi CTC 20 ,017
