Finding an Effective Sustainable Model for a Wireless Metropolitan-Area Network: Analyzing the Case of Pittsburgh
White Paper Many cities are seeking ways to facilitate the deployment of a Wireless Metropolitan-Area Network (WiMAN) based on wifitechnology. City leaders must often balance competing goals, including the desire to maximize the area in which wireless services... [18 Jul 2008]
Exploiting Internet Route Sharing for Large Scale Available Bandwidth Estimation
White Paper Recent progress in active measurement techniques has made it possible to estimate end-to-end path available bandwidth. However, how to efficiently obtain available bandwidth information for the N2 paths in a large N-node system remains an open... [11 Jul 2008]
An Exploration in MAS Scalability
White Paper Naming and capability-mediated services, such as Agent Name Services and middle agents, perform a fundamental task in the Multi-Agent Systems (MAS) infrastructures, because they allow agents to find each other and interoperate. [11 Jul 2008]
On System Scalability
White Paper A significant number of systems fail in initial use, or even during integration, because factors that have a negligible effect when systems are lightly used have a harmful effect as the level of use increases. [11 Jul 2008]
A Scalability Service for Dynamic Web Applications
White Paper Providers of dynamic Web applications are currently unable to accommodate heavy usage without significant investment in infrastructure and in-house management capability. This goal is to develop technology to enable a third party to offer... [11 Jul 2008]
Overcoming NAT and Firewall Connectivity Restrictions in Overlay Multicast
White Paper A large number of overlay multicast protocols have been developed, almost all of which assume universal connectivity between end hosts. However, in reality, this assumption is not valid with widespread use of Network Address Translators (NAT) and... [10 Jul 2008]
Elephant: Network Intrusion Detection Systems That Don't Forget
White Paper Modern Network Intrusion Detection Systems (NIDSs) maintain state that helps them accurately detect attacks. Because most NIDSs are signature-based, it is critical to update their rule-sets frequently; unfortunately, doing so can result in downtime... [30 Jun 2008]
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 network... [24 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 differs from most. Instead of enrolling individual students in online courses, CTE... [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... [04 Mar 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 that can... [19 Feb 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 junk e... [19 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. [19 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 problem), a... [08 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 computer is... [05 Dec 2007]
