D.B5a Service Aggregator – M17
The SLA-aware aggregation of telecommunications services enabled by SLA@SOI presents a business opportunity for the agile and efficient creation of new service offerings. In this document we present the specification of a use case centred on the service-enabling of core telco services and their aggregation with services from third parties. We identify the need for the creation of both a SLA-aware Telecommunications as a Service (TaaS) platform to enable this aggregation and a Business to Business environment in which a telco operator acting as a service aggregator can collaborate with the necessary third parties. This new business environment we envision treats SLA as the foundation to the business of fulfilling service consumption. The TaaS will execute on a virtualized hosting platform providing telco web service endpoints governed by vertical SLAs implemented vertically down through their supporting telco infrastructure. We identify the business areas and values associated with this proposal which we will use for the construction and evaluation of the service aggregator prototype. The necessary
architecture that this document specifies includes the business layer, the software services layer, and the supporting telco infrastructure layer. We outline five scenarios which we will use to exercise and evaluate the architecture, namely 1) the publishing of SLAs for services available for aggregation; 2) the ordering of an aggregate service; 3) the steps relevant to SLAs involved in the operation of an aggregate service; 4) the ability of the customer to retrieve usage information; and 5) the termination of the service by the customer with necessary de-provisioning through the architecture. We conclude with notes on the necessary next steps to realize our ambitions.
