WASHINGTON DC: INTEGRATED NETWORK TECHNOLOGY OVERVIEW Maryland Technology Council June 2006 Chris Peabody Deputy CTO - Office of the Chief Technology Officer Government of the District of Columbia chris.peabody@dc.gov
2
2 Washington DC Unique City / County / State Governance (all in one) Executive Office of the Mayor 66 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 400,000 Residents DC.GOV 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 “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, 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 network technology smokestacks Separate networks – separate programs Separate people, separate budgets, separate helpdesks Politics - real politics – plays a major role in everything Sound familiar?

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 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: Strategic Drivers 1. Need for a high-speed citywide data communications network because of the growing demand for advanced data services, data transport services, and wireless service. 2. Historic problems of service installation delays, problems with access to the city’s data, errors in the telephone bills, and overbilling by telecommunications carriers
10
10 DC-NET: Goals Build and maintain a comprehensive technology network that meets the needs of the ENTIRE District Government All voice services All Intranet WAN 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
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: 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! $93 mil multiyear project Local Capital dollars Some Federal dollars 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 DC-NET currently provides Voice and MAN transport Does not manage LAN/WAN or Internet Both Groups under single Deputy CTO (Peabody)
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 and planned for all sites “which make sense” Some fiber deployed direct in Verizon Conduits Needless to say, Verizon not been happy about this 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 minor/original fiber purchased on IRU’s (Level3)
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 Major Frame Relay networks installed today Multiple 45 Mbps at host sites Independent agencies like DCPS manage their own network 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: 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 28,000+ phones when complete. 28,000+ phones when complete. 13,000 have been ported 20,000 ISDN/CENTREX remain 10 – 15% unused inventory discovered during cutovers Avaya Modular Messaging voicemail Still 10,000 Verizon Optimail boxes not migrated
19
19 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 (SIP or Standard) EC500 has been available for years, not largely 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.
20
20 DC-NET: Terminals Bacground Phone terminals have been problematic Legacy ISDN sets retained because of $$ Most purchased within last 5 years S8700 platform supports these older sets New sites are deploying “newer” digital sets VoIP terminals were not “deployable” in phase I DC LAN/WAN is separate network DC-NET voice traffic is in single Voice VPN VoIP could only be deployed today at “green field” sites Bottom line – we’ve got a racehorse fiber network with world class routing and switching hardware and last generation terminals.
21
21 2007 Terminal Plans Major plans to replace the ISDN terminals We’re backing into VoIP strategy, because of the terminals. We can support ISDN / Analog / Digital /VoIP Major effort underway to upgrade the LAN’s to Support VoIP Power – Power – Power! Working cohesively on a strategy Hiring new people with “end – end” network talent Hiring Sr. Architect + Sr. Project Director Focus on QOS enablement Have to make $5mil+ decisions in 3 months! Concerned about customer care side:

22 Network World: 06/21/06 No waste in Kimberly-Clark VoIP plans For a company that sells billions of disposable consumer products each year, …..conservationist's approach to its VoIP and IP telephony plans. The VoIP plan at Kimberly-Clark is to consolidate voice traffic for more than 200 sites into three data centers while retrofitting existing Avaya PBXs with gear that will turn the devices into digital/VoIP gateways. The revamped PBXs will let the company keep the tens of thousands of digital handsets now in use while centralizing its call processing and messaging applications. That move could save close to $10 million in new IP phone costs if Kimberly-Clark upgrades its sites to VoIP while saving half its Avaya digital phone installed base. "IP handsets will be more of an exception, rather than the rule" in the VoIP road map, says Mike Post, senior manager of IT communication services for the Irving, Texas, company. "For our business and how it operates, we didn't see a great amount of value in deploying IP phones widely... so we're going to try and keep our digital sets wherever we can."

DC-NET/ DC.Gov E911 Network Update June 2006
26
26 DC.Gov: 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 was unreliable, slow, expensive, contained inaccurate data, and had two primary weaknesses: ALI Trunking (pathways)
27
27 DC has built fully a 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 now being migrated System will accommodate VoIP carriers 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 NGN-E911 services should be engineered: Redundant, secure, and on a robust network.

30 DC-NET: Citywide Motorola Radio System 42 Towers across the District Supports entire First Responder Community T1 Based Connectivity Cutover in a single weekend from Verizon Never Failed Adding 28 new circuits due to UCC building
31
31 DC-NET: “Digital Inclusion Wi-Fi” 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
32
32 DC-NET: WARN The Wireless Accelerated Responder Network (WARN) is the nation’s first city-wide broadband wireless public safety network. This pilot network was unveiled in September 04 and was first operationally used in January, 2005 for the Inauguration followed by the State of the Union.
