whitepaper This paper analyzes key Skype functions such as login, NAT and firewall traversal, call establishment, media transfer, codecs, and conferencing under three different network setups. Analysis is performed by careful study of Skype network traffic.
[14 May 2008]
whitepaper The presenter of this webcast analyzes the typical traffic generated by an SMS 2003 Advanced Client during normal processes. For a Systems Management Server administrator, understanding the network traffic patterns of SMS clients is an important...
[02 May 2008]
whitepaper Stateful firewall analyzes packets up to their layer 4 headers while NIDS analyzes the whole packet. This calls for the necessity of analyzing the traffic (packets) on the network. This paper investigates traffic analysis techniques need in...
[24 Apr 2008]
whitepaper With a simple analytical model, this paper analyzes the throughput degradation within a multicast (one-to-many) tree under TCP like congestion and flow control. This paper studies the impact of randomness (i.e.variation of queuing delay due to...
[04 Apr 2008]
whitepaper It analyzes various cost factors to enabling NetFlow in such a network. The paper argues that enabling NetFlow to cover a major portion of traffic instead of the entire traffic will achieve significant cost savings while at the same time give...

whitepaper It also analyzes social networking (Web 2.0) aspects of YouTube. This paper presents a traffic characterization study of the popular video sharing service, YouTube. Over a three month period the paper observed almost 25 million transactions between...
[14 Feb 2008]
whitepaper This paper analyzes the carrier sensing and interference relations between two wireless links and measure the impact of these relations on link capacity on an indoor 802.11a mesh network testbed. In addition, the paper investigates the effect of...
[14 Feb 2008]
whitepaper In particular, it analyzes the statistical properties of the TCP flow arrival process. Different traffic aggregates are defined by splitting the original trace, such that each of them is constituted by all the TCP flows belonging to the same...
[14 Jan 2008]
whitepaper This paper analyzes the dynamic behavior of a single RED controlled queue interacting with a large population of idealized TCP sources, i.e.sources obeying the rules of linear increase and multiplicative decrease.
[14 Jan 2008]
whitepaper To evaluate the impact of peer-to-peer applications on traffic in wide area networks, the paper analyzes measurements from a high speed IP backbone link carrying TCP traffic towards several ADSL areas.
[05 Dec 2007]
whitepaper This paper analyzes the interaction between congestion control and adaptive routing, and study the stability and optimality of the joint system. Most analysis of congestion control assumes static routing, and most studies of adaptive routing assume...
[05 Dec 2007]
whitepaper This paper analyzes TCP's round-trip time estimation for bulk data traffic over wireless links. This paper studies the impact of variable transmission delays on the Transmission Control Protocol (TCP).
[05 Dec 2007]
whitepaper It precisely analyzes how the buffer content of the cell spacer evolves over time. This paper shows that the cell spacing technique can be used to regulate TCP when the traffic of a TCP connection is carried over an ATM connection.
[05 Dec 2007]
whitepaper This paper presents and analyzes user behavior and network performance in a public-area wireless network using a workload captured at a well-attended ACM conference. The goals of the study are: to extend the understanding of wireless user behavior...
[05 Dec 2007]
whitepaper The paper identifies and analyzes separately the two mechanisms within TCP that are responsible for this scaling behavior: timeouts and congestion avoidance. The statistical characteristics of network traffic - in particular the observation that it...
[30 Oct 2007]
whitepaper This paper analyzes the primary challenges of realizing QoS in large scale mobile ad hoc networks and proposes a QoS framework for real-time traffic support. Ad hoc networks have been proposed for a variety of applications where support for real...
[03 Sep 2007]
whitepaper The paper analyzes the performance of two simple MAC protocols, when multi-user interference is explicitly modeled via the received Signal-to-Interference Plus noise ratio (SINR). For example, such protocols could be used to transmit traffic...
[23 Aug 2007]
whitepaper The paper first analyzes the link delay characteristics of MINs. The paper considers a traffic-based network model to characterize these networks. This is followed by a method to obtain the cdf of multi-hop traffic inter-arrival time.
[23 Aug 2007]
whitepaper This paper analyzes the core capacity region of portable wireless networks under a concave utility model for a heterogeneous collection of asynchronous applications such as email and file transfers. The paper shows that there is no relaying among...
