We propose Expeditus, a distributed congestion-aware load balancing mechanism for Clos data center networks. The fundamental challenge in making load balancing congestion-aware is, how to collect real-time (in the order of RTT) congestion information ...

Data centers are increasingly relying on software defined networking (SDN) to orchestrate data transmission. To maximize network utilization, the SDN controller needs to frequently update the data plane as the network conditions change. Due to its ...

The development of various Internet technologies has enabled users to connect to the Internet through a wide variety of access networks and communication terminals. This has brought a great demand for cloud computing which allows users to enjoy various ...

We present performance and fairness analysis of two TCP- based (GridFTP and FDT) and one UDP-based (UDT) big data transfer protocols. We perform long-haul performance experiments using a 10 Gb/s national network, and conduct fairness tests in our 10 Gb/...

The problem of link prediction has gained a lot of attention recently from the research community. It can be formalized as, given a snapshot of a social network at time t, can it be predicted which new connections among its members are likely to occur ...

We present preliminary analysis of energy consumption in a residential academic campus in India. We deployed over 200 smart electric meters across the campus, collecting over 5 million data points every day. The analysis is based on data collected over ...

The ever-increasing number of mobile devices is heavily modifying the traffic observed in cellular networks. From smartphones and tablets to Machine-to-Machine (M2M) devices, the traffic volumes and patterns generated by end-user and M2M applications ...

In dynamic adaptive streaming over HTTP (DASH), a video file is encoded at different bitrates and segmented into small chunks. Each time, the most appropriate bitrate will be selected for a video chunk based on the network condition observed by ...

With over 250 million devices to be sold, wearable devices revenue is forecasted to hit $2 billion by 2018. Wearables are expected to be the next generation of mobile devices. However, before we usher into the era of wearables, there are two key ...

IPv6 addresses contain a 64-bit Interface ID (IID) that is allocated by site administrators. A random IID allows them to reduce the effectiveness of IPv6 reconnaissance attacks. In this paper, we look at how IPv6 IIDs are assigned in practice. In ...

A web-based attack, drive-by download attack, has been posing serious threats to Internet users. There are code analysis based methods and rule-based methods as countermeasures against drive-by download attacks. However, code analysis based methods ...

Various web components and JavaScripts have been used for collecting personal identifiable information resulting in privacy concerns. Although several privacy preserving tools have been proposed to limit online advertising and tracking their use has ...

Many people are concerned about privacy in the Web. This has resulted in the emergence of various tools and suggestions for blocking tracking services. However, in order to block or analyze tracking services, these services have to be identified first. ...

The quality of control plane applications determines reliability of the Software-Defined Networking (SDN). The risk of bugs and challenges for testing actually have been increased due to the programmability of SDN. In this paper, we propose a model ...

Large high-speed networks such as in campuses and enterprises teem with malware infections; current solutions are either incapable of coping with the high data rates, or lacking in effective and speedy threat detection and mitigation. This work presents ...

The mobile core is currently served by gateways having a convoluted control plane and data plane. We abstract and modularize the key functions of these gateways, and separate the control and data plane in nwEPC, an open source implementation of the ...

Interest aggregation is the primary feature of named-data networking (NDN). The interest aggregation reduces duplicated transmissions for multiple requests on the same data, but can delay loss recovery when data packets are lost. Since retransmitted ...
