The Impact of Network Topology on the Spread of Anti-Virus Countermeasures
White Paper Are there properties of networks that affect the spread of anti-virus countermeasures? Is countermeasure spreading more effective through one network than through another? This paper investigates this problem by simulating the impact of... [24 Apr 2008]
Design and Experience With Supporting NAT and Firewall in End System Multicast
White Paper End System Multicast (ESM) is an overlay based architecture to enable multicast in the Internet, and the application-endpoint model of deploying ESM shows tremendous promise because there is no dependence on dedicated infrastructure. [23 Apr 2008]
Carnegie Technology Education: Builds Unique Distance Learning Program on Sun Computing Technologies
White Paper Carnegie Technology Education (CTE), a wholly owned, non-profit subsidiary of the 100-year-old Carnegie Mellon University, offers a distance learning program that... [10 Apr 2008]
Parallel Processing Approaches for Multi Disciplinary Optimization Algorithms
White Paper Multi Disciplinary Optimization (MDO) problems are often encountered in many industrial areas. MDO refers to the optimization of systems of subsystems (disciplines). The optimization of the full system is often reduced to a hierarchy of... [05 Mar 2008]
Exchange Server 2003 Security
White Paper Spam's constantly evolving and mutating nature makes it extremely difficult to separate the good e-mail from the bad. This means that solutions which rely on static detection methods often fail to block an unacceptably high percentage of... [20 Feb 2008]
Preventing Information Leaks in Email
White Paper The widespread use of email has raised serious privacy concerns. A critical issue is how to prevent email information leaks, i.e.when a message is accidentally addressed to non-desired recipients. This is an increasingly common problem... [20 Feb 2008]
Email Alias Detection Using Network Analysis
White Paper The analysis of email addresses in a relational network shows that most aliases tend to occur in close proximity of each other. More than half on the email aliases are located with a geodesic distance of two from each other. [20 Feb 2008]
Approximation Algorithms for Degree-Constrained Minimum-Cost Network-Design Problems
White Paper Several problems in the design of communication networks can be modeled as finding a network obeying certain connectivity specifications. For instance, the network may be required to connect all the nodes in the graph (a spanning tree... [09 Jan 2008]
Enabling File Sharing on a Mac
White Paper Older AppleTalk files servers (those not capable of AppleShare over TCP/IP) are affected by the December 31, 2002 AppleTalk phase-out. If the user accesses an AppleTalk file server located in a different zone than where the user's... [06 Dec 2007]
Improving Wireless LAN Performance Via Adaptive Local Error Control
White Paper Wireless links can exhibit high error rates due to attenuation, fading, or interfering active radiation sources. To make matters worse, error rates can be highly variable due to changes in the wireless environment. [06 Dec 2007]
Improving TCP Startup Performance Using Active Measurements: Algorithm and Evaluation
White Paper TCP Slow Start exponentially increases the congestion window size to detect the proper congestion window for a network path. This often results in significant packet loss, while breaking off Slow Start using a limited slow start... [31 Oct 2007]
Incrementally Deployable Prevention to TCP Attack With Misbehaving Receivers
White Paper In a TCP connection, selfish receiver has incentive to increase its own transmission rate at the expense of other receivers. Whether it is downloading a web page or transferring a file, most receivers prefer the server to focus only on... [31 Oct 2007]
TCP Connections for P2P Apps: A Software Approach to Solving the NAT Problem
White Paper Many P2P applications need to connect to each other via TCP, but are increasingly stymied by NAT boxes. Some popular P2P applications do not address NAT traversal or do so poorly. A few newer ones route communications between NATed peers... [31 Oct 2007]
Detecting DDoS Attacks on ISP Networks
White Paper Most past solutions for detecting denial of service attacks (and identifying the perpetrators) have targeted end-node victims. However, little attention has been given to this problem from an ISP perspective. [24 Oct 2007]
Fast-Growing Robotics Engineering Center Armed With Versatile, Expandable Disk- and Tape-Based Storage Solutions
White Paper The Robotics Institute at Carnegie Mellon University conducts basic and applied research in robotics technologies to boost the productivity and competitiveness of businesses throughout... [11 Sep 2007]
