Media Brokerage: Agent-based SLA Negotiation

Media content personalisation is a major challenge involving viewers as well as media content producer and distributor businesses. The goal is to provide viewers with media items aligned with their interests. Producers and distributors engage in item provision negotiations to establish the corresponding service level agreements (SLA). In order to address automated partner lookup and item SLA negotiation, this paper proposes the MultiMedia Brokerage (MMB) platform, which is a multiagent system that negotiates SLA regarding media items on belhalf of media content producer and distributor businesses. The MMB platform is structured in four service layers: interface, agreement management, business modelling and market. In this context there are: (\textit{i}) brokerage SLA (bSLA), which are established between individual businesses and the platform regarding the provision of brokerage services; and (\textit{ii}) item SLA (iSLA), which are established between producer and distributor businesses about the provision of media items. In particular, this paper describes the negotiation, establishment and enforcement of bSLA and iSLA, which occurs at the agreement and negotiation layers, respectively. The platform adopts a pay-per-use business model where the celebrated bSLA define the general conditions that apply to all established iSLA. To illustrate this process, we present a case study describing negotiation of a bSLA instance and several iSLA instances. The latter correspond to the negotiation of the Electronic Program Guide (EPG) for a specific end viewer.
