    The paper presents PingPair, a novel tool for end-to-end path capacity estimation. The tool is based on the classical packet dispersion technique, enhanced by a novel algorithm for the selection of the best measurement samples based on queueing delay estimation. In addition, PingPair takes into account the measurement noise that afflicts the interarrival times registered by a user level applicatio... View full abstract»

    This paper introduces the HSTCP-H2 AQM controller, an optimal AQM controller for networks which employ the HSTCP protocol as their transport protocol. The synthesis of the controller uses a non-rational approach, in which stability and performance objectives are completely expressed as Linear Matrix Inequalities (LMIs). Results, derived via simulation, show the advantages of adopting HSTCP-H2 rath... View full abstract»

    Originally designed to improve the efficiency of packets forwarding, MPLS provides support for Traffic Engineering and network resilience. Constrained-based path computation is a key building block for Traffic Engineering in MPLS networks, since it allows to set-up LSPs along paths that satisfy QoS constraints. This paper deals with on-line and offline path computation algorithms and, more specifi... View full abstract»

    We consider the design of a P2P network for the distribution of real-time video streams through the Internet. We follow a multi-source approach where the stream is decomposed into several flows sent by different peers to each client. The goal is to resist to the frequent moves of the peers entering and leaving the network. We analyze our approach using the recently proposed PSQA technology which a... View full abstract»

    Achieving minimal loss while satisfying an acceptable delay profile remains to be an open problem under the RED queuing discipline. In this paper, we present a framework targeted at optimal fine tuning of the RED parameters in order to address such problem. For a given traffic pattern and utilizing a statistical analysis of finite-state Markov chains, we formulate an optimization problem aimed at ... View full abstract»

    The complexity of current Internet applications makes understanding network traffic a challenging task. By providing larger-scale aggregates for analysis, unsupervised clustering approaches can greatly aid in the identification of new applications, attacks, and other changes in network usage patterns. In this paper we introduce ADHIC, a new algorithm that clusters similar network traffic together ... View full abstract»

    In this paper, we analyze the performance of the load-level-based admission control mechanism (LLAC) for optical burst-switched networks in a multilink scenario. The goal of this mechanism is to differentiate the blocking probability of a given service class according to the network load and a class-associated parameter, called load level. For the proposed mechanism, we develop a multilink analyti... View full abstract»

    The definition of TCP friendliness has been evolved over time from the traditional one for congestion control protocols to the recent ones for admission control protocols. All of them can effectively prevent the Internet from congestion collapse and TCP starvation, while enabling a wide variety of traffic control protocols other than TCP. However, the current TCP-friendly admission control protoco... View full abstract»

    The emerging IEEE 802.15.4 standard is designed for low data rate, low power consumption and low cost wireless personal area networks (WPANs). Video transmission over such networks is considered an issue since video traffic demands high data rates. In this paper, the TES (transform-expand-sample) methodology is used to model low rate MPEG4 video. The performance of a surveillance video application... View full abstract»

    A novel architecture was proposed in [1] to address scalability issues in large, high speed packet switches. The architecture proposed in [1], namely OBIG (output buffers with input groups), distributes the switch fabric across multiple chips, which communicate via high speed interconnects enabled by proximity communication (PC), a recently developed circuit technology [2]. An OBIG switch aggregat... View full abstract»

    With the popularity of BitTorrent, improving its performance has been an active research area. Super-seeding, a special upload policy for initial seeds, improves the efficiency in producing multiple seeds and reduces the uploading cost of the initial seeders. However, the overall benefit of super seeding remains a question. In this paper, we conduct an experimental study over the performance of su... View full abstract»

    In this paper, we propose an adaptive algorithm called Adaptive REM (AREM) that improves the performance of random exponential marking (REM) in two ways. Firstly, it adaptively controls the parameter alpha to achieve fast response, and secondly, it introduces a new method to evaluate dropping/marking probability with each packet arrival to reduce the queue length jitter. We demonstrate by extensiv... View full abstract»

    The paper proposes a novel measurement-based equivalent bandwidth technique that computes the bandwidth to be allocated to a buffer which conveys heterogeneous traffic (both concerning traffic sources and QoS requirements), without using any closed-form expression. The effectiveness of the algorithm is checked through simulation analysis. View full abstract»

    Multi-path transferring on the different paths with diverse delays would cause reordering and so unnecessary retransmission which eventually degrades the throughput of connections considerably. To address this issue, we first presented an optimal fragmentation strategy that should be held to avoid unnecessary retransmission/recovery timeouts events in TCP or SCTP due to reordering. Then, we introd... View full abstract»

    When transferred in a packet-switched network, the temporal structure of continuous media may be damaged by delay and delay jitter. Compensation buffering is a well-known method to absorb the delay jitter. However, added buffering increases the latency, which may degrade the interactivity between users. As delay and delay jitter are both perceived QoS parameters to users, changing compensation buf... View full abstract»
