TL;DR: In this article, the authors propose a distributed authentication model that operates within a protocol-based sphere of trust, where the external computing systems initially communicate with a specific edge internal computing system, and then delegate the task of authentication to the edge computing system.
Abstract: A distributed authentication model that operates within a protocol-based sphere of trust. Rather than being able to communicate with any one of the computing systems internal to the sphere of trust, the amount of authentication is reduced by having the external computing systems initially communicate with a specific edge internal computing system. Many if not all of the internal computing systems then delegate the task of authentication to the edge computing system, and will rely on any authentication performed by the edge computing system. This allows the task of authentication to scale well for large protocol-based spheres of trust.

TL;DR: The new system architecture has been experimentally evaluated and the results show that the deployment of NEC's CachePortal accelerates the dynamic content delivery up to 7 times while attaining a high level of content freshness.
Abstract: Response time is essential to many Web applications Consequently, many database-driven Web applications rely on data centers that host applications and database contents Such IT infrastructure enables generation of requested pages at locations much closer to the end-users, thus reducing network latency However, it incurs additional complexity associated with database/data center synchronization and data freshness In this paper, we describe the deployment of NEC's CachePortal dynamic content caching technology on a database-driven Web site in a data center-based distribution infrastructure The new system architecture has been experimentally evaluated and the results show that the deployment of NEC's CachePortal accelerates the dynamic content delivery up to 7 times while attaining a high level of content freshness

TL;DR: A prototype system called “Media Companion” which is built to evaluate the design principles is described in the paper, and the experimental results of deploying this system in the corporate network are also discussed.
Abstract: In the past few years we have seen a huge industrial investment on the development of content delivery networks (CDNs) which provide a large number of caches and storage devices at the edge of network to push content closer to the user for fast and reliable delivery. This development has triggered the beginning of a socalled “edge computing” where applications and computational resources are also moving to the edge for intelligent media services. To cope with the growing diversity and heterogeneity of the Internet, these edge servers offer a natural place to extend the capability of network intermediaries for content-oriented services such as automatic adaptation for small devices, personalization, location-aware data insertion and virus scanning. In this paper we present our investigation on using a network of edge servers for delivering content-oriented web services to Internet media. Similar to CDNs, our design goal is to make the content-oriented services part of the Internet infrastructure services accessible to content providers and content consumers via a subscription model. A prototype system called “Media Companion” which is built to evaluate our design principles is described in the paper, and the experimental results of deploying this system in our corporate network are also discussed.
