OH 1 Next Generation Network for Ohio Ohio Digital Government Summit October 2004 OH*1 Project Charter OH 1 Next Generation Network for Ohio Develop an OH*1, Next-Generation Network that is reliable, redundant, and demonstrates quality of service characteristics by effectively aggregating the converged (voice, data, video) communications needs of Ohio state government that includes 120 agencies, boards, and commissions. Allow other governmental entities to leverage the service and/or pricing derived out of the state telecommunication investment. Other governmental entities may include: 384 courts, 118 clerks offices, integrated justice partners, the public, and related state agencies to a secure centralized data repository 2,300 local governments 700 public library facilities Over 2,500 K-12 facilities 1 OH 1 OH*1 Goals Next Generation Network for Ohio Identify Network Alternatives Develop technical, support and financial requirements Surface technology issues Examine feasibility of utilizing a private fiber infrastructure Develop strategic network architecture Design Services (data, video, voice) Security Support 2 OH 1 OH*1 Quality Factors / Principles Next Generation Network for Ohio QUALITY FACTORS PERSPECTIVE SCALABILITY Architecture is modular, utilizes state of art technology and has the capability to scale to future growth and technological change. RELIABILITY Facility utilizes industry standard equipment and protocols and is designed in a fully redundant and fault tolerant fashion. PERFORMANCE Production network utilizes state of art (fiber based) high speed connectivity and processing. AVAILABILITY Facility utilizes fully redundant logical network constructs that increase scalability, optimize fault tolerance and load-balancing, thus ensuring high availability. MANAGEABILITY Facility utilizes processes based on industry best practices and state of the art technology utilizing dedicated secure networks. SECURITY Facility utilizes double firewalls at multiple levels and separates management networks from production networks MAINTAINABILITY Facility provides a dedicated and secure access network to ensure timely and efficient access to state agency applications. PRINCIPLES Modular Design Gigabit Design Vendor Independent Architecture Fully Redundant and Fault Tolerant Design Gigabit Design Redundant WAN Connectivity Multi-Tier Load Balancing Gigabit Design Dedicated Out of Band Management Network Multi-Tier Load Balancing Fully Redundant and Fault Tolerant Design Redundant WAN Connectivity Gigabit Design Dedicated Out of Band Management Network Dedicated Access Network Double Firewall Principle Multi-vendor, multi-layer Firewall Design Dedicated Out of Band Management Network Dedicated Access Network 3 OH 1 Project Approach Next Generation Network for Ohio OH*1 Project Objective: Create a statewide communication vision, strategy, and enterprise architecture with a governance model that reduces operational risk and effectively aggregates bandwidth. Lifecycle Methodology Project Phases Project Kickoff Develop Project Charter Develop Identify Key Deliverables Project Plan key contacts Develop a Strategy for Communications Current Network Architecture Review current network environment Compile and update network documentation Review financial information related to the network Review strategic plans and existing projects Gather and Analyze Network Requirements Identify key sources for business and network detail Collect data via interviews, surveys, focus groups, etc. Document technical and functional requirements Perform Network Traffic and Capacity Analysis Collect critical utilization data on current network Identify new network requirements and project future traffic demands Document analysis Recommend Network Architecture Develop critical design criteria and parameters Identify network architecture alternatives Identify estimated cost Assess impact of new and emerging technologies Develop cost benefit analysis Business Case Development Marketing Plan Development Develop Identify preliminary business case Assess risk and complexity Refine and finalize business case Develop deployment strategy guiding principles and philosophies Define categories of products and target audiences Develop catalog of specific service offerings Identify programs to communicate service offerings 4 OH 1 Current Ohio Infrastructure Next Generation Network for Ohio !

(196 lines out of 13127) 5. 21% of 5393 lines have a presence in the county that a POP for TFN is located. 6. Core WAN protocols include TCP/IP, IPX, Transactional Bridging, AppleTalk, Vines and CLNS. 7. Network Management Applications include HP Openview, IBM/Tivoli, Cabletron Spectrum, CA Unicenter TNG, AT&T Accumaster and SUN NetManager *Source: Network Inventory Database - April 3, 2003 DAS/Computer Services Division/Network Services 6 OH 1 OH*1 Future Network Architecture Next Generation Network for Ohio State Fiber Network and Service Provider Networks will be dual connected to provide additional level of connectivity and redundancy The network addressing tags will be maintained and routing is enabled between the two networks to enable communication between services as required 7 State Fiber Network Design OH 1 Next Generation Network for Ohio 8 State Owned Fiber & Service Provider OH*1 Network OH 1 Next Generation Network for Ohio Description The State Fiber Network would constitute the foundational backbone for the statewide network “Last Mile Connectivity” would be provisioned either to State Fiber Network or Service Provider POP’s depending on distance, availability and cost Interconnectivity between State Fiber Network and Service providers (telco’s, cable, fiber, and wireless) will provide core network redundancy. Routing and switching information would be maintained across the entire network Required services (data, video, & voice) would be made available to the agencies on demand The State may elect to manage the OH*1 network including the ring and switching layers OARnet will manage the fiber ring optics The number of wavelengths (lambdas) enabled would be proportional to the number of services (data, video, & voice) enabled 9 OH 1 OH*1 Proposed Network Map over TFN Next Generation Network for Ohio Toledo !
