Cloud computing has a central role to play in meeting today׳ s business requirements.
However, Distributed Denial-of-Service (DDoS) attacks can threaten the availability of cloud …

Denial of Service attacks are presenting an increasing threat to the global inter-networking
infrastructure. While TCP's congestion control algorithm is highly robust to diverse network …

The current Internet infrastructure has very few built-in protection mechanisms, and is
therefore vulnerable to attacks and failures. In particular, recent events have illustrated the …

We consider a router on the Internet analyzing the statistical properties of a TCP/IP packet
stream. A fundamental difficulty with measuring trafic behavior on the Internet is that there is …

Providing congestion control in the Internet, while ensuring fairness among a myriad of
heterogeneous flows, is a challenging task. The conventional wisdom is to rely on end-user …

Congestion control today is predominantly achieved via end-to-end mechanisms with little
support from the network. As a result, end-hosts must cooperate to achieve optimal …

This paper considers the distribution of the rates at which flows transmit data, and the
causes of these rates. First, using packet level traces from several Internet links, and …

As the Internet becomes increasingly heterogeneous, the issue of congestion control
becomes ever more important. In order to maintain good network performance, mechanisms …

We propose and evaluate a passive measurement methodology that estimates the
distribution of Round-Trip Times (RTTs) for the TCP connections that flow through a network …

This paper presents a new spectral template-matching approach to countering shrew
distributed denial-of-service (DDoS) attacks. These attacks are stealthy, periodic, pulsing …
