ESA is completing the development of the Columbus
Control Centre (COL-CC) and its Communications
Infrastructure (HME-CI)
  • The COL-CC provides
  • Monitoring Control for Columbus (MC),
  • Support for decentralised operations of European
    Payloads in Columbus, US Lab and Russian
    Segment.
  • The HME-CI provides links for service provisions
    to
  • Columbus Control Centre (COL-CC)
  • Autonomous Transfer Vehicle Control
    Centre(ATV-CC)
  • Engineering Support Centres (ESC)
  • International Partners sites
  • Payload User Support Operations Centres (USOCs)
  • REDU ground station for ATV up/downlink
  • ATV-CC relies on NASA MCC-H White Sands or REDU
    ground station for uplink/downlink of TC/TM
  • Columbus system and payload operations are
    performed via NASA MCC-H and White Sands ground
    station

The COL-CC Architecture relies on scalable and
redundant components for critical services
Overview comms Services
  • Comms architecture
  • Redundant central node connecting to all sites
    remote Nodes in a hybrid topology (star from
    COL-CC direct connectivity for ATV related
    sites) via redundant ATM (sites part of the core
    network) and/or ISDN (for backup or to USOCs with
    low bandwidth requirements).
  • In addition ATM point to point for ATV-CC to REDU
    and ATV-CC to MCC-H, ISDN point to point ATV-CC
    to LMX. Satellite connectivity for reduced backup
    between COL-CC and MCC-M.
  • Comms Services
  • ATM and ISDN PRI, BRI
  • IP connectivity (ATV TM/TC)
  • Comms link Protection (e.g. VPN for ATV)
  • Data, Voice, Video Services
  • FTP between COL-CC and remote sites
  • Timing
  • Domain Name Service

Operational Installation in progress Planned
(currently ISDN)
7
The Columbus Ground Segment Architecture relies
on scalable and redundant components for its
Data services. The CD-MCS provides a standard
client implementation for all USOCs.
  • Data System architecture
  • Redundant Kernel at COL-CC serving local or
    remote client connections
  • API implementation at each remote site of Client
    Service (Path TM, processed Data distribution),
    and optionally a Server Service (commands,
    process data contribution)
  • TM Distribution according to CCSDS APID
  • DaSS Data Services CD-MCS client support
  • CCSDS Packet Data Delivery Y
  • Processed Parameter Delivery Y
  • CCSDS Command Forwarding Y
  • Command Echo Y
  • High Rate Bitstream Data Delivery Y
  • Data Modes
  • Real-time (OPS, Sim, Test) Y
  • Playback (from DaSS archive) Y
  • External playback Y
  • Direct delivery of Bitstream Y
  • Deferred and rate-adjusted (bitstream) Y
  • CD-MCS implementation provides
  • Similar SW as in COL-CC (MCS, DaSS)
  • Central configuration with one Mission Database
  • Centrally maintained
  • Processed Data exchange between USOCs via COL-CC

CD-MCS WS
8
The COL-CC Architecture relies on scalable and
redundant components for its Voice system and to
a lower extent for its Video system
  • The voice system provides conference loops to all
    participants. It architecture is based on
  • Redundant Matrices at COL-CC connecting remote
    matrices at Partner sites ATV-CC, MCC-H, HOSC,
    MCC-M, EAC.
  • Dedicated Keysets at COL-CC
  • Dedicated Keysets at User sites via ISDN
    connection.
  • Voice Services
  • Provision of Voice keysets
  • Voice channels (up to 1000)
  • Voice recording retrieval
  • The Video System provides distribution of video
    channels across the Ground Segment.
  • Video Services
  • MPEG-2 over ATM
  • MPEG2 over IP
  • Channel Selection
  • Extraction of Video From High Rate downlink
  • Archiving, recording, retrieval, playback

9
Most other subsystems implement high availability
architectures
  • NIS provides the Network Infrastructure for
    discriminated areas OPS, OPS SUPPORT, and OFFICE
    internal NIS Services include
  • Connectivity, Traffic separation, Network
    Security
  • IMS Integrated Management System, Connects to
    all subsystems Element Managers via SNMP, gather
    equipment status, some level of control of the
    Element Managers
  • Ground Network overview
  • Trouble Ticket System
  • Data, Voice, Video sub-systems overview
  • INFRA_SAN provides servers to host
    mostsubsystems, and a high availability storage
    backup
  • INFRA_GEN Implements Timing, Syslogs, User Rooms
    Workstations, security LDAP architecture
    connecting to ESA PKI (Public Key Infrastructure)
    located at ESTEC/OMT
  • MCS Monitoring and Control s/s provides a
    Central TM and Command server, and peripheral WS.
    CTM hosts the Mission Database (MDB) and a Result
    Database (TRDB).
  • TQVS Services
  • Simulation of Columbus and GS TM
  • Simulation of TC response

10
The Ground Segment architecture scalability
supports delegation of responsibility
  • The architecture provides flexibility through
    scalable systems, dynamic assignments or reserve
    capacity for critical components, e.g.
  • Data system scalable number of servers
  • Data system dynamically assignable processes
  • MCS clients can be added to increase the number
    of console operator Workstations
  • Voice system supporting a number of voice
    channels that largely exceed todays requirements
  • Keysets that can be added at COL-CC or remote
    sites
  • SAN having large storage capacity reserves
  • Standard and customized IGS nodes. A portable
    node connecting via ISDN can be deployed to
    temporary sites
  • Network ports can be added and LAN WAN
    bandwidth can be increased, ATM virtual channels
    added
  • Standard remote client architecture for all USOCs
    (CD-MCS)
  • Etc
  • COL-CC can be configured to support several
    missions with different profiles
  • The design provides flexible capabilities through
    standard, Static or Dynamic scalability that make
    it fit to absorb additional mission requirements
    without incurring redesign.
  • Scalability facilitates the packaging of
    services, and delegating the responsibility for
    accommodating possible changes.

12
The recurrence of activities over a long
duration programme, and a necessary drive for
cost optimisation provide a Rationale for a
Service Concept
  • The Stakeholders and players are
  • the Customer (ESA),
  • the clients (recipients of the service) which
    include also users (beneficiaries of the
    service),
  • the Service provider to ESA (IOT) which integrate
    Service provision to clients and users through
    SLA with various Service Providers (incl. DLR)
    and sub systems suppliers.
  • Goals of a Service Concept for the customer
    (ESA)
  • Externalise recurrent services associated to
    product deliveries or pure operational services
  • Ensure and control service performance
  • Encourage optimisation of service provision
    across multi-mission environments and mission
    profiles
  • Control costs associated to service delivery to
    users/clients
  • Provide a framework to foster cost optimisation
    including internal costs over long duration
    programmes ISS and ATV operations supposed to
    last 10 years
  • Recurrence of activities implies
  • Recurring process oriented tasks to run the
    infrastructure
  • But also concurrent adjustments and their
    validation to meet new mission requirements

13
The Service concept allows ESA to concentrate on
its programmatic objectives
  • ESAs objectives with the Service Concept is to
  • Concentrate on the Exploitation phase
  • ESA objective is to focus on space exploitation
    and delegate the maintenance of the ground
    infrastructure. The infrastructure availability
    is perceived as a service rather than a product.
  • Once the ground segment is qualified, there will
    be limited evolution driven by programmatic
    changes (Contained growth)
  • Delegate to Industry
  • ESA has contracted an Industrial Operator (IOT)
    to manage the multiple organizations involved in
    supporting the infrastructure (DLR, EADS,
    Subcontractors, Suppliers) and support ESA
    maintain interfaces with the International
    Partners
  • Assign a role to industry
  • Stream line performance delivered by Industry
  • Self manage manpower to achieve performance level
  • Drive Cost optimization
  • Let industry deal with manpower and quality
    improvement by setting agreed performance targets
  • Focus its staffing on Agency responsibilities
  • To allow ESA staff to concentrate on
    implementation of programmatic requirements and
    performance management and delegate to industry
    the infrastructure operations.

COL-CC and HME-CI provide Multi-missions support
through the use of generic and specific
capabilities, to serve different users or
clients
Missions/Activities
Internal Users
External Users
  • Missions typically relate to a spacecraft, or
    governing Authority (ESA, NASA, or RSA) and last
    from 10 days to an ISS increment.
  • Activities are ground preparation related.
  • Internal users are located at COL-CC
  • External users are recipients of services through
    the IGS network, the internet, or PTN

Services definition considerstechnical
interfaces, user base, and agreed implementation
supporting planned performance
  • The technical definition of an end to end service
    gather
  • The capabilities of the sub-Systems (e.g.
    provision of voice channels)
  • The characteristics of the technical interface
    (e.g. MPEG2 over ATM or IP)
  • The provision of products to users (e.g. voice
    keysets)
  • The operations realized for the user (e.g.
    extraction of video from High rate channel)
  • The operations realized upon request (e.g.
    archiving, retrieval)
  • The capabilities provided to users (e.g.
    selection of video channels)
  • The service client base include
  • The recipient of the service (on both ends)
  • The user or beneficiary of the service
  • The customer
  • Service characteristics highlight the agreed
    implementation supporting the planned performance
    of service criteria
  • Automated/coordinated (whether the service is
    controlled through an operator)
  • Proactive/Reactive monitoring (whether the
    service is monitored by operator or left to the
    user)
  • Workaround predefined (used to restore even
    temporarily the service)
  • Constraints (e.g. maximum design capacity)
  • Redundancy (e.g. Hot, Cold)

18
Service Control can be achievedthrough the
design of a dashboard for transparent and
effective reporting of performance data
  • Service scope and ESA responsibilities
  • Collecting performance data
  • Sub system engineers report on performance (eg
    downtime..)
  • Service performance assessment and validation
  • Industrial Operator (IOT) Help desk
  • In-situ Tools Periodic scans
  • Annual/bi-annual ESA questionnaire to Users to
    confirm overall IOT figures
  • Service evolution Use of standard templatesplus
    appendices for new/altered services
  • Breach of performance
  • On critical services application of escalation
    procedure
  • On management services penalties
  • On overall user satisfaction handled at SLA

For each phase of a Mission Support, for instance
ATV missions, service requirements are
established by defining e.g. 3 groups of metrics
values - Critical, High, Routine - for each
service.

  • Issues and Challenges
  • Controlled Evolution towards a Service Oriented
    Organisation

23
Issues and Challenges
  • Defining services Determine how a service is
    handled internally by the SP (compared to a
    delivery), setup of objectives, and implications
    on the organisation, coordination across service
    teams and internal reporting.
  • Defining service performance and its measurement
    the measure of down time or repair time, QoS,
    measurement point (user/client, IMS, customer)
  • Dealing with risks associated to external
    dependencies the definition of external risks
    with possible impact on the ability of meeting
    the agreed metrics values, and handling of those
    risks.
  • Integrate the development cycle milestones
    (Detailed Requirements, Design, Testing,
    Verification) for changes driven by programmatic
    decisions, into the Service concept
  • The extent of non assignable ESA responsibilities
    are addressed by a Ground Segment Control Board
    chaired by ESA, which issues directives on
    specific processes, and handles issues with a
    larger scope IPs ICD changes, Flight Safety,
    Ground Segment Security (accreditation,
    revocation of users), Accountability vis a vis
    external Partners.
  • Organizational challenges For service
    performance incentives to be effective, the
    organisation structure and task definition need
    to reflect the flow down of Service Level
    requirements
  • Migration of the initial contract towards a true
    service oriented organisation.

24
The Service Concept allows addressing risks of
different nature (Programmatic, Implementation,
Operations) at different levels, with specific
mitigation responses
  • Programmatic risks ? ESA
  • Schedule uncertainty from an IP or ATV programme
    resulting in e.g. delayed interface tests,
    external implementations ()
  • Cancellation or delay of a mission (mitigation
    cancellation fees)
  • Changes in ground ICDs (ICD changes under ESA
    control)
  • Shortage of funding (minimum commitment)
  • Changing mission requirements (original design
    for scalability and expansion)
  • Implementation risks ? Service Provider
  • Delays in implementing new mission requirements
    (efficient project and risk management)
  • Internal interfaces issues (early detection)
  • Shortage in expertise
  • Mis-performance of Service provider
  • Operations Implementation risks ? Service
    Provider
  • Failures in system (preventative, corrective
    measures)
  • Failures in subsystems or sub-service provider
  • Shortage in expertise (internal training, pool
    and streamlining of personnel deployment,
    personnel multiple qualifications)

25
Through the establishment of SLAs, ESA/HME and
Industry are learning how to reconcile sometimes
diverging interests
  • The Agency seeks mission success at reasonable
    cost

Reconciliation of Diverging Interests
Service Provider Interest tactics
Agency Interest constraints
  • Mission success
  • Risk assessment
  • Decision making in critical phases
  • Costs containment and predictability
  • Reach Confidence through visibility
  • Involve Agency staff in key issues
  • Confidentiality of information
  • Programmatic constraints may drive Termination
  • Provides its core service
  • Seek profitability through advantageous penalty
    scheme
  • Hide own arrangement behind service
  • Fee structure
  • Integrates all Costs
  • Get rewards for financial risk it takes
  • Seek Long term contract

Agency seek SLA focusing on risk / costs tradeoff
(mission success at reasonable cost)
Service Providers tend to provide SLAs focusing
on Financial Scheme and Service Availability

Controlled evolution of the Service definition
and Metrics to ensure that benefits are shared
between ESA and the Service Provider
Necessary Evolution
Action and Anticipated Effect
Current State
  • Service definition mainly in ICD for nominal
    service
  • One Operation Support plan (ATV)
  • Availability requirements not all identified
  • Nominal and degraded service provision need to be
    described for each interface
  • Performance metrics to be reflect agreed targets

Evolution of Service definition
  • OSP need to be established for all ICDs
  • Perform bi-annual reviews of service definition
  • Manpower oriented task
  • Delivery oriented activities
  • Cooperation mindset
  • Evolution of contractor to mindset of taking
    responsibility for a service and associated risks
  • Rationalise the cooperation to a service
    provision
  • Users to Learn how to report on services, accept
    provision on the basis of OSP /SLA
  • Train users, personnel

Gradual and active adoption of a service attitude
  • Internal agreements (NIS to other service
    engineers, service managers)
  • Arising issues to be addressed by a bi-lateral
    SLA team.
  • May lead to off-cycle changes to the SLA and
    renegotiation
  • Heterogeneous nature of the various services
    within COL-CC (e.g. NIS)
  • Homogenise the service provision throughout the
    Control centre
  • Turn project teams into service teams

Differentiation between Services
  • The service provider must have incentives to
    reduce costs in the long run
  • The service provider should identify together
    with ESA further cost reduction strategies and
    share success through incentives.

Incentives for cost reduction
  • System under qualification
  • First initial contract with DLR as a sub/co to
    EADS (IOT) on a 2 year basis for a firm fixed
    price
  • Improvement of efficiency (personnel
    qualification, shifts, )
  • Active response to price reductions (maintenance
    items, obsolescence management,)

Key Performance Indicator definition
  • The KPI and metrics define the expectations of
    end users and of the customer for each individual
    service
  • They must be measurable and valid across
    mission/activities type and services. A subset of
    these indicators may apply to some services.
  • Time to restore the service This is a max time
    to restore the service. In case of redundant
    system, this will be the time to failover. For
    non redundant services, this will be a mean time,
    and in most cases, workaround will be put in
    place.
  • Time to restore the redundancy Once a failure
    occurred on a redundant system, repair is usually
    needed to restore the redundancy. A mean time is
    provided since the recipient is not affected,
    with only the chances that a second failure
    occurs before repair increase with time.
  • Detection Time Time take by operator to detect
    the problem The COL-CC does not rely on service
    recipients to detect failures, especially on
    redundant system.
  • Response Time organizational response upon
    failure detection, or user report e.g. start of
    troubleshooting, of first feed back to the user.
    It influences user satisfaction.
  • Quality Bit error rate, image quality, jitter,
  • Rate kpbs, Mbps

31
Team Organization
  • The adoption of a Service culture distinguishes
    successful Service Providers
  • One of the challenges for most service providers
    is to come up with a service oriented
    organization or grow into a service organization.
  • The Service chain assessment provides input to
    the team organization
  • E.g. SAN contributes to recording/playback voice
    services ? SAN engineers must live through the
    service expectation of voice users (as well as
    data service users, )
  • SLA can be used as clear references to every
    level of the hierarchy on the performance
    expectations.
  • Flow down of the performance requirement from
    Service Level Manager to Sub-system engineers
  • ? Service Engineers, Service Managers, SLA
    managers

The Service-Product continuum need to be
considered when defining the services and
associated performance criteria
  • Service Product continuum where most delivered
    services fall in between pureservice and pure
    product
  • Pure Services have no product associated (IP
    connectivity). The setup of the service
    mayinclude product delivery (IGS Rack,
    encryptingdevices), which will have to be
    controlled andmaintained
  • Pure Products do not exist since the
    servicepart essentially refers to the quality of
    the support or product delivered to the
    customer(or client / stakeholder).
  • Typically the Service part requires specific set
    of processes to the Products ? Service
    Assurance versus Product Assurance
