  3. 3. Definitions SOA is a design for linking business and computational resources (principally organizations, applications and data) on demand to achieve the desired results for service consumers (which can be end users or other services) A paradigm for organizing and utilizing distributed capabilities that may be under the control of different ownership domains. It provides a uniform means to offer, discover, interact with and use capabilities to produce desired effects consistent with measurable preconditions and expectations Service-oriented architecture (SOA) is a style of design, deployment, and management of software infrastructure and applications to create a more flexible digital embodiment of an enterprise service-oriented architecture (SOA) is a higher level of application development that enables IT to focus on business processes, rather than the underlying IT infrastructure, to achieve competitive advantage 3

  10. 10. SOA and Web services  SOA may be built on Web services standards (e.g., using SOAP) that have gained broad industry acceptance. These standards (also referred to as web service specifications) also provide greater interoperability and some protection from lock-in to proprietary vendor software  SOA is often defined as services exposed using the Web Services Protocol Stack . The base level of web services standards relevant to SOA includes the following:  XML - a markup language for describing data in message payloads in a document format  HTTP (or HTTPS) - request/response protocol between clients and servers used to transfer or convey information  SOAP - a protocol for exchanging XML-based messages over a computer network, normally using HTTP  XACML - a markup language for expressing access control rules and policies.  Web Services Description Language (WSDL) - XML-based service description that describes the public interface, protocol bindings and message formats required to interact with a web service  Universal Description, Discovery, and Integration (UDDI) - An XML-based registry to publish service descriptions (WSDL) and allow their discovery 10

  12. 12. SOA Standards/Forum  SOA Standards fall into roughly three categories:  Format standards - SOAP, XML-RPC, REST, EDI, etc.  Service standards - WS-*  Process standards - BPEL, BPMN, XPDL, ebXML, RosettaNet  The primary SOA standards bodies are:  OASIS (Organization for the Advancement of Structured Information Standards)  OSOA (Open SOA)  W3C (World Wide Web Consortium)  WS-I (Web Services Interoperability Organization)  Forum  CBDI ( 12

  16. 16. SOA in Telecom  Accelerates service creation, delivery and monetization, using a very cost-effective services layer architecture  For service providers, SOAs and Web services have the power to open lucrative new markets and generate substantial new revenues by facilitating communication and interaction between the internal and external applications of their customers  SOAs and Web services can profoundly increase the revenue-generation and market-expansion opportunities offered by next-generation network environments  The principles of SOA are currently being applied to the field of network management. eg: SOA network management architectures are TS 188 001 NGN Management OSS Architecture from ETSI, and the recently published M.3060 Principles for the Management Of Next Generation Networks recommendation from the ITU-T SOA  SOA is primarily intended to provide business-level software modularity and rapid reuse of software components  SOA community and Telecoms Operators have not explored enough such an architecture for telecom and network services 16
  17. 17. Telecom Web Services  Telecom Web Services provide the core building blocks that enable a carrier to expose the capabilities of its network to third party application providers and enterprise customers in a secure, controlled, and billable manner  In addition to underpinning a carrier’s so-called “Service Delivery Platform”, providing internal and external access to network resources, Telecom Web Services may be sold as a revenue generating service marketed by the carrier to enterprise customers  Within 3GPP/OSA there is increasing focus on the Telecom Web Service standards and the associated SOA. There is a strong drive to identify and standardize the Telecom Web Services that are necessary to support next generation ASPs and carriers  The evolving OSA Parlay/Parlay X standard, defined by 3GPP, 3GPP2, ETSI and the Parlay Group (the 3GPP TS 29.199 set of standards) provide the essential standards base for Telecom Web Services  With the increasing use of the SOA the TMF NGOSS TAM (Telecom applications map) may become a useful framework for organizing and categorizing Web Services that specify accessibility to offered application/component capability  Telecom Web Services allows network operators to accelerate the adoption of enterprise/IT software concepts such as SOA into the telecoms domain  Provides operators with a cost saving, standardised interface between its network services, its content delivery and applications 17

  19. 19. OSS/BSS Realities  The convergence of OSS/BSS Systems with IMS based upon SOA principles is underway in telecom enterprises  Service providers see SOA as enabling significant improvements in OSS/BSS  Vendors see SOA as driving down OSS/BSS costs  SOA may be particularly beneficial to OSS/BSS development because it is designed to foster communication among many disparate, horizontally distributed components TDM Services TDM Services IP/IMS Services IP/IMS Services Converged Services Market Converged Services Wireless Services requirements Wireless Services Meas/Validation Services Meas/Validation Services lower cost RTUs OSS 1 OSS 2 Cheaper/Faster OSS 1 OSS 2 OSS 3 OSS 4 Integration services Enterprise service bus OSS 3 OSS 4 OSS 5 OSS 6 New OSS OSS 5 OSS 6 Yesterday’s OSS & BSS Systems Today’s SOA – Based OSS & BSS Systems • Common shared service interfaces (opens data) • Pair wise proprietary Point-to-point interfaces • Cheaper/faster integration • Expensive/ Time consuming Integration • Abstracts/Simplifies interfaces • Adding new interfaces impacts existing interfaces • No impact to existing interfaces to add new ones • Complexity not needed in IP world • Flexible coupling/decoupling 19
  20. 20. SOA – BSS Integration  All communications between BSS and the service platform shall go through the service bus (or via a dedicated application in the service platform).  The BSS system can handle the service platform as one component. 20

  22. 22. IMS – SOA Infrastructure platforms  These platforms open doors to the new applications and services  IMS opens up network features (eg. Voice, presence, location) at the service layer  SOA helps to monetize IMS investments  SOA is a defined way of designing, deploying and managing software applications and infrastructure  Applications are separated into modular services  Standard web-based interfaces are used to compile services  Services and business policies are stored in a single directory  QoS components can be assigned to the services 22
  23. 23. Service Delivery Platform based on SOAs  Network operators are now facing a new architectural concept, a platform for service delivery that is entirely decoupled from the network infrastructure and is built on top of Service Oriented Architectures (SOA) and web services concepts  SOAs can be used as an application integration technology within an SDP but are best served when used in the lower performance functions such as connections between the transactional OSS and BSS applications and the SDP  SDP is based on the principles of SOA and reusability, providing a common set of functions and a common way to view the underlying network. Increasingly SDP standards are coming into the telco world from the IT sector  Service orchestration technologies (such as BPEL) is becoming part of emerging SOA SDPs, enabling services to be composed from telecom functional blocks and blocks of business logic from the IT domain Next generation SDPs : SOA enabled SDP 23
  24. 24. Services….. Caller ID on IPTV  Using IPTV, the service provider can provide various value-added services like caller ID (This service enables a user who is watching the TV receive voice call identification on the TV screen and then provides the option for pausing & recording the video stream for the duration of the call)  If the underlying implementation is based on SOA, new providers and new equipments is easily incorporated and able to produce services with a fast time to market. This includes new types of set-top boxes as well as residential GW’s at the end-users premises. Also the network configuration benefits from the SOA approach, as in new network equipment can be added from new vendors as well. 24
  25. 25. Why to migrate towards SOA ?  maturity of SOA basic technologies and products  reduced gap between: Telco and IT solutions  service layer not replacing, but complementary to existing service frameworks (e.g., IMS, Web, IPTV)  requirements for “blended” applications (eg. content-delivery + communication)  push to address new business models aligned with the trends of Internet & SoC (Service oriented computing) 25
  26. 26. Challenges faced by service providers  Declining revenues  Displacement of fixed voice services with VoIP  Declining of ARPU from mobile services & applications  Increased competition  Competition from cable operators  New entrants into the market (Google, Vonage, yahoo….)  Organization impacts  Limited collaboration among sales, OSS/BSS & provisioning  Legacy processes and systems unable to support new models  Network convergence  IMS network architecture initiatives  Consolidation drives FMC 26
