Over the last few years, the idea of network function virtualization (NFV) has become widespread, shifting the workload of hardware-based middleboxes onto applications on commodity hardware. Virtual machine is the common building block of the NFV ...

Network Functions Virtualization (NFV) aims to move network functions away from expensive hardware appliances to off-the-shelf server hardware. NFV promises higher flexibility and cost reduction for the network operator. In order to achieve high ...

The key technology of NFV is software dateplane, which has attracted much attention in both academia and industry recently. Yet, in practice, there is very little understanding about its performance till now. We make a comprehensive measurement study of ...

Software-defined networks (SDN) do not guarantee coherent network operations, when uncoordinated SDN applications concurrently update the network forwarding state. As this problem has not so far received considerable attention, in this paper, we ...

To test and update switch operating systems, developers and testers need to install run beta-switch OSes (switch agents) alongside production versions. However, today's network virtualization solutions fail to support infrastructure-level virtualization ...

Managed services for the home have traditionally been shunned by Internet Service Providers (ISPs) as having high overheads and low margins. In this paper we argue that the maturing ecosystem around Software Defined Networking (SDN) changes the equation,...

In-network services, usually implemented through middle-boxes, play a key role in today's Internet. They enhance end-to-end connections with the ability to provide content optimization, performance enhancement, privacy protection, etc. Multiple in-...

Providing fine grained traffic measurement is crucial for many network management tasks such as traffic engineering, anomaly detection, traffic accounting, and load balancing. Software-defined networks can potentially enable fine-grained measurement by ...

Live Virtual Machine (VM) migration is an important technology for cloud management and guaranteeing a high service quality. However, existing studies are mainly focusing on improving migration performance but without much consideration of user's ...

It is well expected that a collection of smart objects such as IoT devices dynamically form an edge cloud allowing acquiring, storing, communicating, and processing of information done at the edge of the network. Edge cloud workers (i.e. IoT devices) ...

Massive trajectory data with spatio-temporal information are generated from various devices everyday. Due to a wide variety of devices and data collection methods, these data differ in terms of frequency and precision, which brings challenges to data ...

Many attacks target vulnerabilities of home IoT devices, such as bugs in outdated software and weak passwords. The home network is at a vantage point for deploying security appliances to deal with such IoT attacks. We propose a comprehensive home ...
