摘要

The introduction of the Ubiquitous Web requires many adaptation and personalization services to tailor Web content to different client devices and user preferences. Such services are computationally expensive and should be deployed on distributed infrastructures. Multiple topologies are available for this purpose: highly replicated topologies mainly address performance of content adaptation and delivery, while more centralized approaches are suitable for addressing security and consistency issues related to the management of user profiles used for the adaptation process. In this paper we consider a two-level hybrid topology that can address the trade-off between performance and security/consistency concerns We propose two distributed architectures based on the two-level topology, namely core-oriented and edge-oriented. We discuss how these architectures address data consistency and security and we evaluate their performance for different adaptation services and network conditons.
