Optimized service integration

Abstract: An optimized service mediation framework may use customized tokens for reducing cost and latencies per transaction. In particular, a token service and an integration service may function together to generate customized tokens for use by network components within a transaction pathway. Each network component may access information with the token for a predetermined time period and/or for a predetermined number of service calls for service processing tasks related to mapping, security, governing, bridging, transforming, orchestrating, generating events, managing workloads, routing, validating, managing cache, encrypting, queuing and staging, commodity services, transaction management, and quality of service (QoS)/resiliency, among other things.

Spock: Exploiting Serverless Functions for SLO and Cost Aware Resource Procurement in Public Cloud

Abstract: We are witnessing the emergence of elastic web services which are hosted in public cloud infrastructures. For reasons of cost-effectiveness, it is crucial for the elasticity of these web services to match the dynamically-evolving user demand. Traditional approaches employ clusters of virtual machines (VMs) to dynamically scale resources based on application demand. However, they still face challenges such as higher cost due to over-provisioning or incur service level objective (SLO) violations due to under-provisioning. Motivated by this observation, we propose Spock, a new scalable and elastic control system that exploits both VMs and serverless functions to reduce cost and ensure SLO for elastic web services. We show that under two different scaling policies, Spock reduces SLO violations of queries by up to 74\% when compared to VM-based resource procurement schemes. Further, Spock yields significant cost savings, by up to 33\% compared to traditional approaches which use only VMs.

Interactive service quality in service encounters: empirical illustration and models

Abstract: Although the performance of services is done at an operative level, service is an important issue for the strategic, tactical, and operative business activities of companies. This paper examines the construct of interactive service quality in service encounters. This is a complex approach that goes beyond the current exploration of the service‐quality construct. Interactive service quality requires the simultaneous consideration of the service provider's perspective and the service receiver's perspective. The study was conducted in the Swedish automotive industry and focused on the issues of interactive service quality between a vehicle manufacturer and a selection of its most important suppliers. The major contributions of the research provide an on‐the‐spot account of interactive service quality. The paper provides theoretical and managerial implications of the construct of interactive service quality in service encounters.

Utility modelling, equilibrium, and coordination of resource service transaction in service-oriented manufacturing system:

Abstract: The resource service transaction in service-oriented manufacturing systems is one of the key issues in deciding its practical implementation and application. In order to enhance the benefit of the three sides or users (i.e. resource service provider, resource service demander, and resource service agent or operator (agent)) using service-oriented manufacturing systems, the comprehensive utility models consider the revenue, time, and reliability for the three sides in the resource service-transaction process faced with uncertain factors under decentralized decision-making conditions are established first. Then the related comprehensive utility model for the resource service transaction chain of ‘multiple resource service providers – one agent – multiple resource service demanders’ under a centralized decision-making condition is proposed and discussed. The existence of utility equilibrium between resource service provider and agent is studied and proved. As is the optimal decision of a resource service tra...

An agile service interaction manager for intelligent network services

Abstract: A method and system for responding to a trigger condition detected during the handling of a call connection in an intelligent network (IN). Upon receipt of an IN trigger, a service interaction manager (40) in a service control point (14) queries (37) a home location register (60) for a subscriber involved in the call connection requesting subscriber subscription information. The service interaction manager also queries (95) a service library (50) associated with the service control point to determine which of an implicated set of services are currently available in the service library and what the properties of those services are. Depending upon which services are available, which services are in the subscriber's subscription list, and the service priority information received from the home location register and the service library, including the properties data from the service library, the service interaction manager reduces the list of implicated services to an applicable set of services and generates a customized execution sequence for the applicable services. Thereafter, at least one of the applicable services is executed (108) in accordance with the customized execution sequence.
