Fueled by need to rapidly transmit findings during Covid pandemic, time required provide peer review ultimately make data available readers been focus intense scrutiny. result development preprint servers, which ability post results completed research manuscripts onli...

A cluster-based architecture with a proxy and a few back-end servers is a popular solution to face the ever increasing demand for data-intensive services. Stateof-the-art Cluster-based servers employ a proxy that is responsible for distributing incoming requests to the back-end server in a manner that is transparent to clients. The back-end servers send the response to the proxy, which then for...

Secure multiparty computation (MPC) as a service is becoming a tangible reality. In such a service, a population of clients wish to utilize a set of servers to delegate privately and reliably a given computation on their inputs. MPC protocols have a number of desired properties including tolerating active misbehavior by some of the servers and guaranteed output delivery. A fundamental result is...

Most of the web user’s requirements are search or navigation time and getting correctly matched result. These constrains can be satisfied with some additional modules attached to the existing search engines and web servers. This paper proposes that powerful architecture for search engines with the title of Probabilistic Semantic Web Mining named from the methods used. With the increase of large...

CDNs play a critical and central part of today’s Internet infrastructure. In this paper we conduct extensive and thorough measurements that accurately characterize the performance of two large-scale commercial CDNs: Akamai and Limelight. Our measurements include charting the CDNs (locating all their content and DNS servers), assessing their server availability, and quantifying their world-wide ...

Distributed file systems that scale by partitioning files and directories among a collection of servers inevitably encounter cross-server operations. A common example is a rename that moves a file from a directory managed by one server to a directory managed by another. Systems that provide the same semantics for cross-server operations as for those that do not span servers traditionally implem...

Multimedia content delivery in IMS, including IPTV, is handled by a separate unit, the Media Function (MF), made up of media control and media delivery units, which in the case of IPTV are the Media Control Function (MCF) and Media Delivery Function (MDF), respectively. According to the different specifications of an IMS based IPTV architecture, the User Equipment (UE) is expected to use the RT...

The softwarization of mobile networks enables an efficient use resources, by dynamically scaling and re-assigning them following variations in demand. Given that the activation additional servers is not immediate, up resources should anticipate traffic demands to prevent service disruption. At same time, more than strictly necessary results a waste thus be avoided. stringent reliability require...

Current resource provisioning schemes in Internet services leave servers less than 50% utilized almost all the time. At this level of utilization, the servers’ energy efficiency is substantially lower than at peak utilization. A solution to this problem could be dynamically consolidating workloads into fewer servers and turning others off. However, services typically resist doing so, because of...
