DC-NET Goals

• Implement a citywide broadband fiber-optic private voice/data network for the District Government.

• Satisfy education and public safety communications requirements.

• Interconnect over 300 District govt. offices, data centers, PD, FD, schools, libraries and “partners” (e.g. WASA, UDC and Convention Center).

The fiber network serves as the foundation for all major technologies going forward.

DC-NET Project Approach

• Deliver data services first, starting at center of city and working out toward outlying areas.

• Two data centers already interconnected (DWDM).

• DC-NET data and voice services will be available to about 80% of the DC government by the end of 2003.

DC-NET Design• 9 Major Backbone loops – 30 Secondary Loops• Acquired through IRUs and cable franchise agreements• Approximately 30 secondary fiber distribution loops• 2 NOCs manned 24x7• Full suite of network management applications and

GUI-based provisioning• High reliability 99.98% availability architecture NEBS 3

carrier grade battery backup • No single points of failure at Critical Buildings • Secure, alarmed equipment cabinets with remote

monitoring• OC-48 backbone. Upgradeable to OC-192 and DWDM.

DC Net Design• DC-NET uses Multi-Service SONET provisioning

– GUI based provisioning

– Battery backup to operate through a loss of commercial power

– Meet all the requirements including the transport of E911 traffic

– Scaleable to meet the Districts needs throughout the life of the project.

Requirements and Services

• Support Existing Protocols– Ethernet (TCP/IP)

– Voice

– TDM

– Traffic lights/telemetry

– Video Conferencing (point-to-point and interactive)

– Webcasting (point-to-multipoint)

– Storage Area Networks (SANs)

– ATM

Requirements and Services

• Network is managed from two redundant NOCs• Network management applications include:

– HP Openview/OVO – with agents on all servers

– Remedy Help Desk – (also District wide help desk)

– Remedy Inventory

– Remedy Change Management

– Micromuse Netcool to monitor security events

– Infovista for Performance Management

– Cisco Works for WAN equipment

– Hummingbird for X-Windows

Requirements and Services• No single point of failure on the backbone or tributary

rings– Key locations have diverse entry when possible– Single entry conduits are encased in concrete 3’ or deeper

in the ground

• Backbone rings have 24 strands of fiber• Tributary rings have 18 strands of fiber• Scalable

– Support year 5 demands at initial deployment– Easily upgradeable to year 10 demands– Scaleable to year 15 demands without a major equipment

(forklift) upgrade

DC-NET Business IssuesInvestment/ROI:• Project cost = $93 million.

$66 million available.• $27 million shortfall will be

paid out of savings.• Savings ROI = $10 million per

annum when built out (2005).• Savings start when we begin

“cut-over”, fall 2003. – First few high-population

buildings will produce most savings.

Business Strategy:• We are not going into the “phone

business”.

• Will contract for all operations services that can feasibly be contracted.

• Proposed entrepreneurial entity to own/operate DC-NET will increase ROI.

– E.g. Sell services to WMATA and Convention Center.

– This fall, will propose legislation for this purpose.

DC-NET Conduit Routes

• Black box: “Fire zone”.• Inside fire zone: all fiber

in underground conduit.• Outside fire zone: fiber

may be in conduit or aerial.

• 9.5% of DC-NET is planned to be in Verizon conduit (or “duct”).

DC-NET Conduit Law

• Operative DC Code provision:– § 34-1911.05…; provided,

that in all conduits,… space shall be furnished to the District… as may be necessary for its fire alarm or police patrol wires or cables…, free of charge; and…the number of ducts…shall not be more than 3.

• Replacing old lead-shielded cable with new fiber-optic cable.

• Work to upgrade cable from old to new continues…
