OH1 Project Charter

• Develop an OH1, 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

• 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

Current Environment

1. 98.5 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.
4. 1.5 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, ATT Accumaster and SUN NetManager

OH1 Future Network Architecture

• 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

State Fiber Network Design
10
State Owned Fiber Service Provider OH1 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
  POPs depending on distance, availability and
  cost
• Interconnectivity between State Fiber Network and
  Service providers (telcos, 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 OH1 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

OH1 Network Architecture
Advantages Risks
Highly redundant Since two diverse independent networks (private fiber service provider) will be used, high redundancy may be achieved Highly scalable Since the optical backbone is leveraged, services can be enabled on demand Increased Last Mile Options, due to additional POP locations and service provider options 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 POPs The two networks need to exchange routing/switching information leading to complexities Operational and service complexities Management and control issues
