Agenda• Program Overview

• Segment 1

• Segment 2

• Governance

• Cloud Computing

Program Concept

• SWIM will:―Implement a Service Oriented Architecture (SOA) in the NAS

by providing Enterprise Infrastructure services that include messaging, security, enterprise service management, and interface management

―Oversee and govern the implementation of cloud computing in the NAS

―Ensure adherence to common standards (Governance)―Allow the FAA to create new system interfaces more quickly

and cost-effectively than is possible today―Facilitate the data-sharing that is required for the Next

Generation Air Transportation System (NextGen)

SWIM is an Information Technology (IT) infrastructure program that operates in the background to provide data to authorized users to facilitate

collaboration across National Airspace System (NAS) domains

Segmented Approach to SWIM• SWIM Segment 1:

― Implementation of a set of federated services in the NAS with SWIM-provided governance, standards, and software to support development of reusable SOA services

― SWIM provides requirements, schedule, and funding to seven other NAS programs (i.e. SWIM Implementing Programs (SIPs)); tracks progress via formal monthly reviews

― Segment 1 results in SOA services deployed to all Air Route Traffic Control Centers (ARTCCs), 37 Terminal Radar Approach Controls (TRACONs), the Air Traffic Control System Command Center, the William J. Hughes Technical Center (WJHTC), and NAS Enterprise Management Centers (NEMCs)

• SWIM Segment 2:― Continues provision of governance, standards, and software to

additional NAS programs― Implements enterprise messaging service for NAS programs and

facilitates transition by Segment 1 SIPs

66



Core Services ComponentsCore Services supported by SWIM include:

• Interface Management - interface specification, discovery, and schema management

• Messaging - reliable messaging as well as publish/subscribe services

• Security - authentication, authorization, and audit services

• Enterprise Service Management - service monitoring, service configuration, and system monitoring

ITWS information accessed via InternetITWS information accessed through ITWS Situation Display

•There are more than 10,000 airports in the US, yet fewer than 100 Air Traffic Control Towers have direct access to ITWS Situation Displays

•SWIM enables ITWS information to be accessed by those without direct access, facilitating common situational awareness

NAS Service Registry/Repository (NSRR)

• A Service Registry is a resource that provides controlled access to data necessary for the implementation and governance of SOA projects

• A Repository is a database containing the artifacts and metadata that constitutes a SOA registry

• The NSRR is SWIM’s Registry/Repository for NAS Services

• Registering with the NSRR will be the only way to receive FAA NAS data

SWIM Segment 2 • In November 2010, the FAA Joint Resources Council (JRC)

created procedural path for SWIM to become the Governance Agent for SOA in the NAS

– SWIM to provide the enterprise SOA infrastructure within the NAS for individual programs to use

– SWIM will support efforts to ensure that SOA Governance complies with NAS Governance

– Specific SOA tools are being prototyped as Segment 2 candidates

• Segment 2 prototyping has identified new opportunities that may reduce cost and risk of Segment 1 services

– NAS Enterprise Messaging Service (NEMS) to be provided via FTI, building on the ASDE-X prototype

15



SWIM Segment 2 Enterprise Infrastructure

• Domain Name Service (DNS) provides naming and name-to-address resolution services across the Enterprise

• Network Time Protocol (NTP) and Precision Time Protocol (PTP) provides time synchronization services across the Enterprise

• NAS Enterprise Messaging Service (NEMS)

16



NEMS Overview

• NEMS support for NAS Reliability, Maintainability, and Availability (RMA) requirements

• Any service available on one NEMS node will be available on any other NEMS node

• Intelligent Routing, routing decisions made based on certain data attributes or pre-defined conditions

• Data Filtering, based on Java Messaging Service (JMS) message header contents or attributes of the Extensible Markup Language (XML) schema

• Meets Enterprise Boundary Protection (EBP) requirements through integration with the NESG

NEMS is providing Messaging Services for the NAS

17



NEMS Messaging Capabilities• NEMS supports two Message Exchange Patterns (MEPs):

– Publish/Subscribe – Request/Response

• In the Publish/Subscribe MEP, senders (Publishers) send messages to receivers (Subscribers) through Message Broker service

• Subscribers express interest in receiving only specific messages, based on a message topic

• Two main advantage of the Publish/Subscribe pattern are: – loose coupling– scalability

18



NEMS Messaging Capabilities (cont.)

• In the Request/Response MEP, a requestor sends a request message to a producer that receives and processes the request, ultimately returning a message in response

• Request/Response allows two systems to have a two-way conversation with one another over a messaging channel

• Request/Response is typically (but not always) implemented as a SOAP-based Web Service– NEMS provides a simple proxy capability and transports the data via

HTTP from the Message Producer to the Message Consumer

– Most commonly this pattern is implemented synchronously

19



NEMS Deployment Highlights• Current NEMS deployment includes messaging nodes at:

– Atlanta and Atlantic City NESGs– FTI National Test Bed (FNTB) (Atlantic City)– Research and Development (R&D) Domain (Atlantic City)

• Dedicated messaging nodes in the NESG are utilized as an interface between NAS and non-NAS entities

• Four internal NAS nodes will be installed at the beginning of 2012– Used for NAS-to-NAS distribution of SOA data products – Node Locations: ACY, ZTL, OEX, ZLC

• Tentative end-state architecture will utilize 23 internal NAS nodes – 21 Air Route Traffic Control Centers (ARTCCs) (including Alaska) – ACY and OEX

Scope of SWIM Governance

SWIM Governance is a catalyst for improving overall NAS, Air Traffic Organization (ATO) and FAA governance

It’s a part of FAA GovernanceWhat is FAA/ATO/NAS governance?

Establishing decision making rights associated with the FAA/ATO/NASEstablishing mechanisms and policies used to measure and control the way FAA/ATO/NAS decisions are made and carried out

What is SWIM governance?

Extension of NAS governance focused on the lifecycle of services to ensure the business value of SWIM

ATO Governance

NAS Governance

FAA Governance



• SWIM Compliance Definition:– “Verified conformance to SWIM Policies.” (SWIM Service

Lifecycle Management Processes v1.0)

• Verification Mechanisms– Manual review of artifacts– Governance-enabling technology

• NSRR• Testing Tools (Actional, Lisa, etc…)• SWIM Web Service Security Compliance Test Kit (SWIM WS-S CTK)• Policy Servers• XML Gateways• Enterprise Service Management (ESM) software

SOA Suitability Criteria• NAS Enterprise View

– Potential for existing SWIM service to be utilized or tailored to meet the requirement

– Potential for other users to benefit from the information exchange

– Potential hazards for exposing data through SWIM (e.g., proprietary data, non-FAA user access)

• Program View (Cost, Schedule, Technical)– Life-Cycle Cost of SWIM versus other solutions

– System performance requirements: latency, transmission rate, bandwidth, response time, overhead, etc.

– Safety/certification requirements

– Information security requirements

– Existing architecture/vendor solution impacts

FAA Cloud Computing Approach• FAA NAS and non-NAS organizations are working

collaboratively on adoption of cloud computing under the leadership of the FAA Chief Information Officer (CIO)

– SWIM is responsible for managing the implementation of cloud computing in in the NAS

– The FAA Information Technology (IT) Operations Lead Team is responsible for oversight and guidance for FAA’s non-NAS IT infrastructure, including cloud computing

32



The SWIM website describes the SWIM program and provides news, announcements, and information on current issues

It also contains key documentation, including select briefings, the SWIM Newsletter, and the SWIM Q&A
