PDAs and smartphones are increasingly being used as handheld computers. Today, their network connectivity and their usages for various tasks over the Internet require privacy and authenticity. In this paper, we conduct a comprehensive and comparative ...

Communities of Interest (COI) have been studied in the past to classify traffic within an enterprise network, and to mitigate denial-of-service (DoS) attacks. We investigate the use of Communities of Interest (COIs) to prioritize known good traffic on ...

This paper presents a design for an end-to-end transport protocol for multi-homed end systems that pools the communication resources of multiple network paths to support a single communication session. This approach offers improved performance and ...

In this paper we present the Distributed Overlay Anycast Table, a structured overlay that implements application-layer anycast, allowing the discovery of the closest host that is a member of a given group. One application is in locality-aware peer-to-...

Networking devices today consume a non-trivial amount of energy and it has been shown that this energy consumption is largely independent of the load through the devices. With a strong need to curtail the rising operational costs of IT infrastructure, ...

We propose a new TCP-friendly multicast congestion control for very large groups of receivers. This protocol named M2C is layered and receiver-driven. Like TCP, M2C is composed of a Congestion Avoidance and a Slow Start state. However, M2C can re-...

Monitoring network traffic and classifying applications are essential functions for network administrators. In this paper, we consider the use of Traffic Dispersion Graphs (TDGs) to classify network traffic. Given a set of flows, a TDG is a graph with ...

In this work we propose to use path information to improve the reliability of the Internet. Previous work put forth a simple idea of using an overlay network of intermediary detour nodes that can be used to route around failures on direct Internet paths ...

The transmission bandwidth consumed by delivering rich content, such as movie files, is enormous, so it is urgent for ISPs to design an efficient delivery system minimizing the amount of network resources consumed. To efficiently deliver web content, a ...

Link state routing protocols such as OSPF or IS-IS currently use only best paths to forward IP packets throughout a domain. The optimality of subpaths ensures consistency of hop by hop forwarding although paths, calculated using Dijkstra's algorithm, ...

Internet Service Providers (ISP) have been recently relying on Deep Packet Inspection (DPI) systems, which are the most accurate techniques for traffic identification and classification. However, building high performance DPI systems requires an in-...

In this work we tackle the problem of on-line backup and storage with a peer-to-peer approach. We propose a novel system architecture involving the users' devices that confederate by pooling their resources and offer an alternative to capital-intensive ...

In this paper, we investigate the performance of limited reconfigurable optical networks when multihopping is used. Multihopping is achieved by dropping a wavelength at an intermediate node and transmitting on another wavelength at that node (O-E-O). A ...

This paper describes qualitatively and through applications the comparison of PBB-TE and T-MPLS/MPLS-TP approaches to Carrier Ethernet. Carrier Ethernet has currently been proposed as a method to transport Ethernet in metro networks with carrier class ...

Optical buffering is one of the main obstacles in optical packet switching (OPS) networks. We proposed the network global control strategy to resolve this problem. By introducing the cycled traffic at the edge node and the slot assignment algorithm at ...

Recently, several papers have studied the possibility of shrinking buffer sizes in Internet core routers to just a few dozen packets under certain constraints. If proven right, these results can open doors to building all-optical routers, since a major ...

With the ever-increasing wireless multicast data applications recently, considerable efforts have focused on the design of self-adaptive flow control schemes for wireless multicast service. This paper proposes a novel and efficient distributed flow ...

In optical wavelength-division multiplexing (WDM) networks, recent technological progress is enabling dynamic optical transport in which leasable circuits (connections) can be set up and released for a specific duration of time, providing large capacity ...

The hybrid optical wireless (HOW) network has been viewed as a promising solution to meet the increasing user bandwidth and mobility demands. Due to the basic differences in the optical and wireless technologies, a challenging problem lies in the Media ...

Flow optimization and data compression methods promise to improve TCP performance, and edge devices that implement them to transparently improve wide-area network performance are currently being developed. We present an experimental study of TCP ...

Looking into the future, this paper presents the effects of having packets of large sizes, called XLFrames (XLFs), in a network. The analysis is motivated by the fact that the Internet is soon to witness stupendous amounts of traffic that have to be ...

We propose an optical circuit switching node architecture with automatic neighbor discovery. It implements a trunk module attached to an all optical switching element, which exchanges test messages with neighbor nodes to identify interface addresses of ...

Many emerging science experiments require that the massive data generated by big instruments be accessible and analyzed by a large number of geographically dispersed users. Such large scale science experiments are enabled by an Optical Grid ...

There are an increasing number of high-performance networks that provision dedicated channels through circuit-switching or MPLS/GMPLS techniques to support bulk data transfer in large-scale science or e-commerce applications. These dedicated links are ...

With continuing speed increases of communication links found both inside and outside the servers in a data center, link power management is becoming an important issue. In this paper we examine width control of such links and show that it provides ...

We present a multi-path computation algorithm to find a set of paths for the given demand and use Integer Linear Programming (ILP) approach to derive an optimal solution to maximize the achievable bandwidth and minimize the required memory size. We ...

This paper describes simulation analysis of an optical packet switch that has a limited capability to "see" packets that have not yet arrived at the input port. The goal of the effort is to design a variable-length optical packet switch without random ...

Peer-to-peer is emerging as a potentially disruptive technology for content distribution in the mobile Internet. In addition to the already well-known peer-to-peer file sharing, real-time peer-to-peer streaming is gaining popularity. This paper presents ...

The demand for video content is continuously increasing as video sharing on the Internet is becoming enormously popular recently. This demand, with its high bandwidth requirements, has a considerable impact on the load of the network infrastructure. As ...

With the increased popularity of mobile multimedia services, efficient and robust video multicast strategies are of critical importance. In a conventional multicast system, the source station transmits at the base rate of the underlying network so that ...
