Online services have difficulties to replace passwords with more secure user authentication mechanisms, such as Two-Factor Authentication (2FA). This is partly due to the fact that users tend to reject such mechanisms in use cases outside of online ...

While monitoring system behavior to detect anomalies and failures is important, existing methods based on log-analysis can only be as good as the information contained in the logs, and other approaches that look at the OS-level software state introduce ...

Network Function Virtualization (NFV) and Software Defined Networks (SDN) do not leave any legacy network services untouched. This work will present how Proxy Mobile IPv6 (PMIPv6) can evolve to the cloud. Our approach is to introduce this evolution ...

The disruptions caused by Network Function Virtualization (NFV) and Software Defined Networking (SDN) introduce severe impacts also on mobility management. In this work, we will show how IP-based mobility management, especially Mobile IPv6 (MIPv6), can ...

Open Source Software (OSS) has come to play a critical role in the software industry. Some large ecosystems enjoy the participation of large numbers of companies, each of which has its own focus and goals. Indeed, companies that otherwise compete, may ...

Jetstream is the 1st production cloud facility for research funded by the National Science Foundation (NSF). As part of the NSF eXtreme Digital (XD) program, Jetstream's goals are to:

• Aid researchers across the United States with modest amounts of ...

Jetstream, built with OpenStack, is the first production cloud funded by the NSF for conducting general-purpose science and engineering research as well as an easy-to-use platform for education activities. Unlike many high-performance computing systems, ...

This paper presents networking design strategies in cloud infrastructure built using Openstack platform and explore scalability issues related to its infrastructure. Experiments discussed in this paper are conducted to study the performance of Openstack ...

Virtual switches are a crucial component of cloud operating systems that interconnect virtual machines in a flexible manner. They implement complex network protocol parsing in the unified packet parser - parsing all supported packet header fields in a ...

Jetstream is the first production cloud funded by the NSF for conducting general-purpose science and engineering research as well as an easy-to-use platform for education activities. Unlike many high-performance computing systems, Jetstream uses the ...

The Internet of Things is a fast-growing and pervasive reality, and millions of physical entities - from consumer products to transport vehicles, are recorded and tracked in time and space. Smart City projects are becoming suitable platform for exploring ...

With the development of cloud computing, the current Software Defined Networking (SDN) data center which is based on the Open Source Cloud platform OpenStack cannot satisfy multiple users' service requirements. OpenStack cannot achieve centralized ...

An increasing amount of popular services are utilizing cloud infrastructure due to its convenience, low cost, and scalability. However, as more services turn to cloud as a means of storing and delivering data to consumers, the faults of cloud ...

Like any other distributed system, cloud management stacks such as OpenStack, are susceptible to faults whose root cause is often hard to diagnose and may take hours or days to fix. We present GRETEL, a system that leverages non-intrusive system ...

A way to merge cloud computing infrastructures with traditional or legacy network deployments, leveraging the best in both worlds and enabling a logically centralized control. A solution is proposed to extend existing cloud computing software stacks so ...

prevent attackers from gaining control of the system using well established techniques such as; perimeter-based fire walls, redundancy and replications, and encryption. However, given sufficient time and resources, all these methods can be defeated. ...

The sharing of large amounts of data is greatly facilitated by the adoption of cloud storage solutions. In many scenarios, this adoption could be hampered by possible concerns about data confidentiality, as cloud providers are not trusted to know the ...

Many small and medium size research groups have limitations to execute their HPC workloads because of the need to buy, configure and maintain their own cluster or grid solutions. At the same time, some research groups have large infrastructures with low ...

Cloud service providers typically adopt the multi-tenancy model to optimize resources usage and achieve the promised cost-effectiveness. Sharing resources between different tenants and the underlying complex technology increase the necessity of ...

Network Virtualization Functions (NFV) and Software-Defined Networking (SDN) are changing the landscape of the telecommunications industry, particularly infrastructure and network systems of Telco operators with the introduction of cloud computing, ...
