Transcript DC-Net Goals

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.

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 Issues
Investment/ROI:
Business Strategy:
•
•
•
•
•
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.
•
•
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…
