Next Generation Network for Ohio OH 1 Ohio Digital Government Summit October 2004

1 OH 1 Next Generation Network for Ohio OH*1 Project Charter 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

6 OH 1 Next Generation Network for Ohio % of the lines currently on State of Ohio Multi-Agency Communications Systems (SOMACS) contract* will be affected by the expiration of the contract. (12931 lines out of 13127) 2. There are 7538 Lottery Analog lines that are part of the SOMAC contract. 3. The remaining 5393 lines support DS0, DS1, DS3, OC3, 0C12, OC48, FE, GE traffic throughout the agencies % of the lines currently on other contracts will not necessarily expire at the same time as SOMACS. (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 Current Environment *Source:Network Inventory Database - April 3, 2003 DAS/Computer Services Division/Network Services

7 OH 1 Next Generation Network for Ohio OH*1 Future Network Architecture n State Fiber Network and Service Provider Networks will be dual connected to provide additional level of connectivity and redundancy n The network addressing tags will be maintained and routing is enabled between the two networks to enable communication between services as required

8 OH 1 Next Generation Network for Ohio State Fiber Network Design

9 OH 1 Next Generation Network for Ohio State Owned Fiber & Service Provider OH*1 Network 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

10 OH 1 Next Generation Network for Ohio OH*1 Proposed Network Map over TFN

11 OH 1 Next Generation Network for Ohio OH*1 Network Architecture n Highly redundant : Since two diverse independent networks (private fiber & service provider) will be used, high redundancy may be achieved n Highly scalable: Since the optical backbone is leveraged, services can be enabled on demand n Increased ‘Last Mile’ Options, due to additional POP locations and service provider options n Potential for lower cost per location: Since two options will be available to each location, sites can be provisioned after taking into account last mile options Connection via Service Providers Connection via State Fiber Network POP’s n The two networks need to exchange routing/switching information leading to complexities n Operational and service complexities n Management and control issues AdvantagesRisks
