Abstract
To ensure our warfighting edge in information superiority across all joined forces, we must keeppace with technology advancement and build a state of the art network infrastructure that canadapt to changing needs and provide fast and reliable service delivery anytime, and anywhere inthe world. This paper addresses the challenges that the Defense Switched Network (DSN) faces,and offers a Configuration Management (CM) solution that is built upon a common DSN CoreCM database with automated support systems to support integration of various NetworkManagement functions.
1.0 IntroductionThe primary function of the Defense Switched Network (DSN) is to provide non-secure dial-upvoice service. It also supports Switched Data and dial-up Video Teleconferencing (VTC) for theDepartment of Defense (DOD) common-user video teleconferencing system. The DSN supportsthree types of users: Special C2 Users, C2 Users, and Other Users.
Within DSN, there are multiple organizations that take part in the overall DSN Program. Eachorganization is responsible for a certain operational functions and performs a sub-section of theConfiguration Management process (identification, audits, control, and status accounting). MostCM functions are performed manually and have received minimal automated support. This wasdue to Operations and Maintenance needs, which dictated that automation efforts focus on Faultand Performance management.
1.1 Purpose
This paper addresses how Configuration Management (CM) will be enhanced, automated, andapplied in support of the Defense Switched Network (DSN). It includes the approach indeveloping requirements, a summary description of the functional model used in analyzingexisting processes and modifying and/developing additional processes, the operational concept,the development and implementation approach and current status.
1.2 Limitation
This paper focus on the DSN and its long-haul circuit switched services. Other networks andservices within the Defense Information System Network (DISN) are not being addressed hereinbut will be incorporated after the DSN CM is operational.
1.3 Background
To ensure our warfighting edge and information superiority across all joined forces, we mustkeep pace with technology advancement and build a state of the art network infrastructure thatcan adapt to changing needs and provide fast and reliable service delivery anytime, anywhere inthe world. To achieve this objective, DISA must form a solid foundation that combinesintelligent network platforms with sound management principles and a well-engineeredinformation infrastructure. With this foundation, DISA can capitalize on new technologies whilecontinuing to meet our rapid customer service and applications delivery requirements. Figure 1
depicts the overall transformed DSN concept and its role in the future telecommunicationsenvironment.
Figure 1 Transformed DSN Concept and Vision
As shown in Figure 1 the key element that integrates all entities within the foundation underDISA’s control as well as those entities external to DISA is Configuration Management (CM).Without CM it is almost impossible to satisfy performance requirements. Therefore DISA isconstantly looking to improve its CM capability. The criticality of good CM becomes mostobvious in tension-crisis situations where system elements must be quickly adjusted or deployedwith high reliability in an unstructured situation. Much time and performance is saved when thefield forces “get it right the first time”.
This paper will articulate how CM will be applied in support of the vision for long-haul inter-switch circuit switched services and end–to–end Command and Control circuit switchedservices.

2.0 Current System Description
DSN consists of multiple systems and sub-systems that represent voice circuit switches(Multifunction Switches and End-office Switches), transmission facilities, timing andsynchronization, signaling, operation centers, integrated network management systems, varioussoftware and hardware components, and customer premises equipment. It interconnects with theMilitary Department’s (MILDEP’s) base/post/camp/station facilities to provide inter-basecommunications. Refer to Figure 2 below.
Figure 2 Defense Switched Network (DSN) System Overview
Due to the diverse geographical locations, DSN is further separated into four operating Theaters:WESTHEM (including Continental US (CONUS), Puerto Rico, the Azores, and Iceland), Pacific(including Alaska), Europe, and CENTCOM (previously Central Area/Southwest Asia). Due tothe unique environments, the network within each Theater consists of different vendor hardware,software, operating procedures, and support systems.

3.0 Approach/SolutionDefense Switched Network (DSN) Configuration Management is the technical andadministrative process used to identify and document functional and physical characteristics ofthe DSN network. CM also controls changes to those characteristics, records, and reports onchange processing. CM ensures that proposed changes to the network’s configuration arereviewed and approved by management before implementation. Once implemented, networkchanges are confirmed and recorded. This process helps ensure the baseline network areefficiently managed and network data is accurately presented to support other networkmanagement functions i.e. fault management, performance management, accountingmanagement, and security management.
Because CM data form the basis to support other Network Management functions, it is mostcritical to have a common set of tools and automated system support to ensure CM data ismaintained and shared amongst all the functional groups. In addition, interface agreements andprocedural guidelines (Practices and Procedures, P&P’s) must be established to guide the day-to-day operation of the DSN.
Figure 3 Network Management/CM Information Integration
To combat the challenges that DSN faces, a systematic approach is required to model the currentDSN functions and activities and document/analyze its existing processes. This will help toestablish an overall operational concept; determine process re-engineering; generate automatedsystem support and Practices & Procedures enhancement requirements. Figure 4 illustrates thisapproach.

Figure 4 DSN CM Approach
The current DSN implementation must be captured and analyzed to form a System Model. Thissystem model provides a blueprint of the DSN functions to include management, planning,engineering, provisioning, and operations. The associated processes within DSN and supportsystems must also be documented and analyzed. The analysis of current DSN processes andsupport systems will help to determine the user and automated support system requirements, aswell as to identify immediate improvements. The current DSN system model will reveal thenetwork elements necessary to operate and manage the DSN as a whole as well as its theaterspecific requirements. The network elements will include all the critical network componentsneeded to provide services to the user community.
An over all DSN CM Operational Concept that is independent of hardware, software andnetwork restrictions must be formed to meet the users’ requirements. The current/existingdatabase systems must be compared to this Operational Concept and network elementrequirements resulting from the DSN modeling. This will allow the formation of implementationpriorities and phase-in approaches that lead to database integration and standardization whileminimizing the impact on existing operations.

4.0 DSN CM Functional Model
The DSN management model for CM comprises of functional layers that are tailored toDepartment of Defense (DOD) voice services and networks. The DSN CM Model is developedusing information from DOD standards and guidance, as well as commercial industry standardsand practices, these including:
q DOD, Military Handbook for CM (MIL-HDBK-61a)q DSN Configuration Management Planq ISO/OSI Basic Reference Model for Network Managementq Telestrategies, Operational Support System – Functional Matrixq ITU-T, Telecommunications Management Network (TMN)
Figure 5 DSN CM Functional Model
The 8-layer model focuses on the Management Functions of DSN Configuration Management:
Layer 8: The Business Management Layer represents the highest layer where all high-leveldecisions and strategies are being made.
Layer 7: The next layer of Service Management Layer provides additional feasibility planningof the DSN technologies, configurations, service features, and P&P’s.

Timing/Synchronization systems, and other transport and switching technologies arebeing engineered.
Layer 5: The Network Services Layer focuses on the end-to-end delivery of DSN services(voice, data, and video) to the end-users.
Layer 4: The Link Management Layer provides the management functions for Inter-SwitchTrunks (IST) and access lines that are providing transport the DSN services.
Layer 3/2/1: Each of the lowest three layers (Physical Management Layers) are dedicated tothe functional management of Physical Unit (PU, Layer 3), Physical Sub-unit (PSU,layer 2), and Physical Component (PC, Layer 1).
These eight (8) layers represent the transitioning of Planning (at higher levels), Engineering,Provisioning, Installation, and Operations/Change Recording (at lower levels) within the DSNConfiguration Management structure. There are two-way interactions between each layer andmost interactions are from top down (i.e. from a higher layer to a lower layer).
4.1 Model Comparison
The DOD Military Handbook for CM addresses the procurement and configuration managementstandards for weapon systems. It does not offer a configuration management reference model.The DSN CM Functional Model incorporates the functionality from the DSN CM Plan andHandbook, along with other functions from the ISO (OSI Model), ITU-T (TMN Model), andTelestrategies (OSS).
The OSI Basic Reference Model addresses the interconnection and communication of an opensystem. The DSN CM Functional Model focuses on the various configuration managementfunctions that are specific to Defense Switch Network (DSN). The OSI Model deals with theopen system’s software, hardware, and application. Therefore, the OSI model can only berelated to the DSN’s first five layers (i.e. from Physical Layer up to Network Services layer).The remaining DSN CM Functional Model management layers (Network Technology, Service,and Business) are not covered by OSI.
The ITU-T model is the Telecommunications Management Network (TMN) model. This ITU-Tstandard is used for managing telecommunications networks and the services they provide. TheDSN CM Functional Model resembles the TMN management model.

5.0 Operational ConceptThe critical element of this operational concept is having a common DSN database with a coredatabase structure which allows access by all CM functions. This will allow a standard processof evaluation/recommendation/approval prior to implementing the network changes. Once thechanges are implemented, they will be uniquely identified, audited, and stored within the DSNCore CM Database.
Figure 6 illustrates the proposed DSN CM Operational Concept.

5.2 DSN CM Database System
The DSN database will provide system interfaces to other existing DSN support systems such asnetwork requirement ordering, provisioning, engineering, planning, accounting, management,and other administration systems. This will facilitate the information sharing necessary tosupport the CM processes of identification, audit, change control, and status accounting. Figure7 shows the DSN CM operation concept with the automated support systems.

Figure 7 Overall DSN CM Operational Concept
Establishing a DSN CM Database with a core database structure is the critical path in building asuccessful DSN CM Program. The core CM database contains only the installed and operationalDSN network elements, and it provides the support for the automated CM support systems andother DSN support systems.
DSN Configuration Management users include Management, Operations, Maintenance,Engineering, and Administration personnel. These users can be located locally (MILDEP),within each Theater, or at the Global level. Users at multiple levels and locations can access thiscore database structure to perform various DSN functions.
System interfaces must be provided to share and exchange information with other DISA systemssuch as Telecommunications Certification Office Support System (TCOSS), World-Wide On-Line System Replacement (WWOLS-R), Defense Information System Database (DISD), andContract Support System (CSS) that are critical to the DSN operations. Users can rely on theautomated support system to support their daily operations such as network/traffic engineering,planning, cost accounting, etc…
Advance Defense Switched Network Integrated Management Support System (ADIMSS) willprovide a platform for all database functions and automated support necessary for DSN CM.While there are various system applications that support individual DSN function (i.e.financial/accounting, planning/engineering, provisioning/installation, etc…), the core CMdatabase within ADIMSS will provide the central data depository for the critical ConfigurationItems (CI’s) that are common to all DSN functions.

database tracks all critical Configuration Items (CI’s) that are common to other DSN databasesand support systems. The common CM database structure applies across all theaters (CONUS,Europe, Pacific, and CENTCOM). This will allow interoperability and accessibility at the globallevel.
The following is an example of the DSN CM Database levels and their CI’s:
Figure 8 DSN CM CI Levels
DSN CM users at different levels (i.e. Global, Theater, and Local levels) can access the coredatabase and data mart to perform their specific tasks (i.e. performance management and faultmanagement). The overall ADIMSS/CM Database Administrator will control user access to datathat is outside of their level.
The core DSN CM Database should include configuration items from the following majorcomponents:

The Technical Data Storage (TDS) will support all on-line CM requirements such as storage oftechnical specifications, network routing information, Practices & Procedures, and otherinformation that is not associated with the operational plant (e.g. non-core/plannedimplementation). The Data Mart will allow users to store data from multiple sources, includingthe core database, and customized data for their specific applications.

6.0 Summary of Current Status & Implementation Plan
Implementation of the above Operational Concept and Core Database Structure must be carefullyplanned and program managed. It must minimize the impact on the existing operational networkand network management systems.
Currently, the DSN CM functional model is completed. Existing operational processes aredocumented and being analyzed. A list of the immediate initiatives that will improve the short-term DSN operations was provided. A proof of concepts is completed on the automated DSNtopology tracking based on a common database of network elements (DSN voice switches andtrunks). The documentation of automated support system and Practices/Procedures (P&P)requirements are completed. Likewise, the initial requirement to establish a level structure forthe Configuration Items (CI’s) within the DSN database is completed.
