We present a new approach for integrating virtualized FPGA-based hardware accelerators into commercial-scale cloud computing systems, with minimal virtualization overhead. Partially reconfigurable regions across multiple FPGAs are offered as generic cloud resources through OpenStack (opensource cloud software), thereby allowing users to “boot”(More)
Software-Defined Infrastructure (SDI) presents an approach for integrated management of virtualized heterogeneous resources. Monitoring and measurement is an essential component for effective control and management. This paper presents an architecture of a system, named MonArch, based on SDI that provides integrated monitoring and measurement(More)
This paper presents a novel architecture to manage identity and access (IAM) in a Multi-tier cloud infrastructure, in which most services are supported by massive-scale data centres over the Internet. Multi-tier cloud infrastructure uses tier-based model from Software Engineering to provide resources in different tires. In this paper we focus on design and(More)
Many multicast services such as live multimedia distribution and real-time event monitoring require constructing a multicast mechanism that involves network functions (e.g. firewall, video transcoding). Network Function Virtualization (NFV) is a concept that proposes using virtualization to implement network functions on infrastructure building block (such(More)
Network function visualization (NFV) has emerged as a promising paradigm in networking, where the hardware-based middleboxes are replaced with software-based virtualized entities typically running on the cloud to provide specific functionalities. By deploying NFV, network services become more adaptive and cost-effective. Many multicast services such as(More)
This paper discusses the role of virtualization and software-defined infrastructure (SDI) in the design of future application platforms, and in particular the Future Central Office (CO). A multi-tier computing cloud is presented in which resources in the Smart Edge of the network play a crucial role in the delivery of low-latency and data-intensive(More)
Many multicast services such as live multimedia distribution and real-time event monitoring require multicast mechanisms that involve network functions (e.g., firewall and video transcoding).

In this paper we discuss how to enable Software-Defined Networking (SDN) applications on Software-Defined Infrastructure (SDI) which is an approach for integrated control and management of converged computing and networking resources. Current separated resource management for computing or networking resources is not sufficient for addressing applications(More)
In this paper, we present a new platform for experimenting with networked systems and distributed applications called Virtualized Application Networking Infrastructure (VANI). This infrastructure is designed as a converged communications and computing infrastructure that would facilitate operation of an open applications marketplace. VANI enables(More)
In this paper we present an approach to implement security as a Virtualized Network Function (VNF) that is implemented within a Software-Defined Infrastructure (SDI). We present a scalable, flexible, and seamless design for a Deep Packet Inspection (DPI) system for network intrusion detection and prevention. We discuss how our design introduces significant(More)
