2 Washington DC Unique City / County / State Governance (all in one) Executive Office of the Mayor 76 Agencies Elected City Council Independent Agencies Public Schools CFO Water and Sewer Authority (WASA) Major Federal Oversight and funding Primary business is government No Smokestack industry allowed DHS is having a major impact on city Business is currently very good
3
3 Washington DC Approximately 500,000 Residents Government presence in over 600 locations within the city. Major Federal presence Hub of a major urban metropolis Dulles – Baltimore and beyond Major Schools GU / GWU / American / Catholic / Howard / Trinity
4
4 OCTO www.octo.dc.gov Office of the Chief Technology Officer Formed in 1998 with 4 employees Over 600 employees & contractors today Centralized technology support All agencies under the Mayor Not Independent Agencies Agencies managed own technology before OCTO Very similar to HEC “Worst to First” District Website DC.Gov named Best of the Web The portal was named Best of the Web by the Center for Digital Government, a national research and advisory institute on information technology policies and best practices in state and local government Major ERP initiatives complete or underway Amazing network and public safety initiatives
5
5 OCTO www.octo.dc.gov Undergoing major transformation right now Moving from entrepreneurs to production programs Major emphasis on transforming contractors to FTE’s Network has grown in “smokestacks” Major Peabody task is integration of technology Groups are in technical smokestacks Separate networks Technology programs are in separate smokestacks Separate people, separate budgets, separate helpdesks Sound familiar? Much like HEC used to be! Politics - real politics – plays a major role in everything
6
6 OCTO HAS BEEN VERY BUSY “In order to great things in the world of technology you need to have 2 very critical things: Great people and lots of money. OCTO has been blessed with both over the last few years.” Suzanne PeckCTO - OCTO
7
7 DC Gov’t Networks In-Source Vs Out-Source Most network services were outsourced CENTREX telephony service MAN data circuits all from ILEC Public Safety networks from traditional vendors Contractors versus FTE’s In process of complete reversal Citywide/city owned and managed communications networks. Key: District owned and managed Shift from Contractors to FTE’s
8
Ultimate In-Source Solution Build it yourself!
9
9 DC-NET: Goals Build and maintain a comprehensive technology network that meets the needs of the ENTIRE District Government All voice services All data Intranet connectivity Enhance Public Safety applications Working group determined that the network must have “at least” these attributes: Scalable (especially future growth; both size and services) Highly available, fault-tolerant Minimize total cost of ownership, particularly operational costs Secure (traffic isolation and privacy) Accommodate the wide variety of network needs and data flow patterns present in the District
10
10 DC-Net: Unique Architectural Issues in DC Different agencies have different data flows Some have flows that are centralized on an agency HQ or data center Some have flows that are centralized on the OCTO Data Centers (different sites than Agency data centers) Some use site-to-site flows (eg: video conferencing) Multi-agency buildings Security (and resulting costs) Addressing and routing hierarchy
11
11 DC-Net: Architectural Issues In The District Many agencies require encryption Extranet connections need to filter/firewall their traffic before it reaches other agencies Redundancy Different preferences, requirements, budgets, etc. Some agencies are 100% stand-alone, others use centralized resources such as e-mail Bottom Line: Much like a campus, the Districts network needs and applications differ by agency, by building and by budget.
12
12 DC-NET: Options Overview Considered a variety of options - variety of approaches: Different types of equipment considered Different layers of the OSI model considered for service delivery “Legacy,” “mature,” “state-of-the-art,” and “bleeding edge” technologies were all considered Impact of teams ability to effectively manage/administer Both point-to-point and shared (cloud) models Consistent factors DC Net should be the transport mechanism not desktop All traffic should use SONET as the “convergence layer” Ethernet over SONET vs. a separate Gigabit Ethernet network Ethernet aggregation at the edge of the network for cost savings, while maintaining necessary resiliency levels.
13
13 DC-NET Fast Facts DC Loves Teddy Roosevelt 1903 Statute required “the phone company” to provide conduit space for public safety use. Very powerful discovery! $48 mil multiyear project Local Capital dollars Some Federal dollars Post 9/11 interest in improving communications between Feds, DC and surrounding areas Goal is to be self sustaining by FY08 Approximately 86 employees working on the project Currently in “Construction and Production” Final production team should be substantially smaller Must maintain fiber splicers - Help Desk specialists DC-NET currently provides Voice and MAN transport Does not manage LAN/WAN or Internet
14
14 DC-NET: Independent Agency? Plan has been to “spin out” DC-NET into an Independent Agency This is on again, off again. Requires full support from EOM and Council New Mayor elected next year Requires “full time “driver”” Independent agency not “hamstrung” by same “inane Gov’t rules and regulations” Can become an Erate eligible Company Can provide services to Federal Agencies Can provide services to non-Gov’t entities
15
15 DC-NET: Fiber SONET Fiber planned to all Gov’t locations 400 – 600 Gov’t sites across the city Currently at 165 buildings All citywide voice and data services at sites “which make sense” will eventually be riding these fully redundant SONET rings Some fiber deployed direct in Verizon Conduits Needless to say, Verizon not been happy about this Have tried unsuccessfully to stop deployment in courts & PSC Other fiber obtained via CATV Franchise Agreements Comcast 23 Additional miles just obtained in “fire zone” Great to have, but hard to integrate into network RCN (formerly Starpower) Some original fiber purchased on IRU’s
16
16 DC-NET: Core and Edge electronics Cisco 15454's as the core routing hardware Other than one major software issue, very stable Chosen for it’s carrier class abilities Chosen because “they’re Cisco” over other vendors Chosen for it’s ability to support SONET SONET chosen for it’s proven redundancy (circa 2003) Great for T1 Handoffs Lots of Government Applications for T1’s Motorola Radio circuits to Towers (42 of them across the city) Voice circuits for ancillary products like ACD Cisco 3750’s currently used at edge Edge is almost always at the BDF
17
17 DC-NET: Replacing the Legacy Services Rapidly replacing legacy MAN circuits from Verizon District has hundreds of Point – Point circuits T3 through Analog circuits deployed across the city In 2001, over 3500 analog circuits were installed Major Frame Relay networks installed today Multiple 45 Mbps at host sites Independent agencies like DCPS manage their own network DC Gov still pay’s about $5mil/year for MAN circuits to Verizon DC-NET replacing these circuits as fast as possible Layer 3 MPLS VPN’s Currently offer 2Mbps – 500Mbps T1’s also provided Pricing of DC-NET services currently mirrors Verizon fees to ensure no impact to agency budget. DC-NET “costs” still hard to determine at this phase
18
18 DC-NET L3-MPLS VPN: Pros, Cons & Verdict Pros L3-MPLS VPN provides all the “usability” benefits of a “Global VLAN” based network without the disadvantages Much more scalable Much better traffic tuning and optimization tools L3 routing protocols and MPLS Traffic Engineering versus Spanning Tree tuning Cons Adds a degree of complexity to the overall District network Verdict Provides the optimal mix of flexibility, scalability, control, and operational efficiency for a District-wide data network

20
20 DC-NET: Voice Platform Avaya s8700 is core voice platform. Redundant servers in two host centers Connected via DC-NET SONET fiber MCI (now Verizon) provides PRI + DID numbers Service provided from 2 CO’s 30,000+ phones when complete. 30,000+ phones when complete. 12,000 have been ported 25,000 ISDN/CENTREX remain 10 – 15% unused inventory discovered during cutovers Migration is very, very, VERY challenging Avaya Modular Messaging voicemail Still 10,000 Verizon Optimail boxes not migrated
21
21 DC-NET: Terminals Phone terminals have been problematic Legacy ISDN sets retained because of $$ Most purchased within last 5 years S8700 platform supports these older sets Pro’s: Each port on switch supports 2 stations Con: Antiquated NT1/Power supplies Are going to start deploying “newer” digital sets VoIP terminals not “deployable” yet DC LAN/WAN is separate network VoIP could be deployed today at “green field” site VoIP strategies are actively being engineered Bottom line – we’ve got a racehorse fiber network with world class routing and switching hardware and last generation terminals.
22
22 DC-NET: Terminal Plans Voice terminal plans mirror most large enterprise plans: Get out of the “Henry Ford Phone business” Any set you want as long as it’s my black phone… SIP (of course) Single number on multiple terminals EC500 has been available for years, not deployed First responder’s anxious for single number Hardphone Softclient on “rugged - ized” laptop in cruiser Cellphone Utilize private 700Mhz spectrum to deploy softclients for first responders and other Gov teams.
23
23 DC-NET: NOC NOC is carrier class / world class 24 x 7 x 365 Underground Redundant center in planning stages Hub of all.gov technology performance mgmt Actually doing application management not just monitoring & performance mgmt DC-NET opted to outsource to legacy OCTO NOC Critical to DC-NET success because of mission critical applications on-net
24
24 Some $$$$$ DC has been spending about $8mil/year for data circuits DC has been spending about $15mil/year for voice services Current DCNET expenses $15mil/year Includes major capital build out of fiber/hardware Includes all new software license fees Includes a lot of people “to build” “Break Even” on voice:about 18,000 lines Projected expenses post cutovers:$10mil/yr

District of Columbia E911 Network Update February 2006
27
27 Direct Connect Overview 90% complete with modernization of District’s E911 Network 8 years ago, DC’s Verizon-managed 9-1-1 system was the worst in the country. Verizon’s existing technology is unreliable, slow, expensive, contains inaccurate data, and has two primary weaknesses: ALI Trunking (pathways) Since then, DC has built fully redundant E911 network infrastructure that enables Carriers to “Direct Connect” to the PSAP All wireless (cellular) carriers have been on the District’s “selective router” system for 4 years. 50+% of the traffic to PSAP is cellular. Wireline carriers are being migrated onto the system now. System will accommodate VoIP carriers as well 0 calls have been blocked or dropped in 4 years Call delivery and processing has dramatically improved National Emergency Number Association (NENA) has reviewed the District 911 network and believes the District’s network is how E911 services should be engineered Redundant and secure, on a robust network.
28
28 Direct Connect Overview 10% Remaining to Finish the Job Completing migration of wireline carriers to selective routers With exception of Verizon, all 13 carriers providing wireline phone service in the District are engaged in the process or are connected via reliable trunks. So far, Verizon has refused to meet. Migrating carriers/calls onto the new UCC telephone system UCC systems add increased redundancy via back- up at McMillan (PSCC) Competing the ALI (Automatic Location Identification) service Texas and Allegheny County, PA have done this. Texas passed supporting rules. DC/OUC must complete rulemaking regarding ALI and engineering standards.

37
37 DC-NET: “Phili Wi-Fi” backbone Mayor gets calls and Emails every day “Why does DC not have a network like “Phili”? Currently exploring “win – win” options Looking for partners Not sure where the $$ will come from DC-NET will provide citywide backbone for network service partner
38
38 Antenna Site Leases (TALL Program) (OCTO) manages a program for leasing space on government property and buildings to telecommunications and wireless companies that want to install antennas in the District of Columbia. Leases may be obtained through the Telecommunications Asset and Location Leverage (TALL) program, which is being established in concert with the Office of Property Management (OPM). The program currently has over 300 sites available for antenna installations by lease agreement. TALL recognizes that the need for new antenna sites in the District of Columbia will grow as existing personal communications services expand and third generation ("3G") wireless services are introduced.
