- Towards Virtual Networks for Virtual Machine Grid Computing
- Virtual machines can greatly simplify wide-area distributed computing by lowering the level of abstraction to the benefit of both resource providers and users. Networking, however, can be a challenge because remote sites are loath to provide connectivity to any machine attached to the site network by outsiders. This paper explains...

- IDGraphs: Intrusion Detection and Analysis Using Histographs
- Traffic anomalies and attacks are commonplace in today's networks and identifying them rapidly and accurately is critical for large network operators. For a statistical Intrusion Detection System IDS, it is crucial to detect at the flow-level for accurate detection and mitigation. However, existing IDS systems offer only limited support for...

- Towards a High-Speed Router-Based Anomaly/Intrusion Detection System
- Traffic anomalies and attacks are commonplace in today's networks, and identifying them rapidly and accurately is critical for large networks. With the rapid growth of network bandwidth and fast emergence of new attacks/worms, existing network Intrusion Detection Systems IDS are insufficient for the following two reasons. First, they are mostly...

- Reverse Hashing for High-Speed Network Monitoring: Algorithms, Evaluation, and Applications
- A key function for network traffic monitoring and analysis is the ability to perform aggregate queries over multiple data streams. Change detection is an important primitive which can be extended to construct many aggregate queries. The recently proposed sketches are among the very few that can detect heavy changes online...

- A Poisoning-Resilient TCP Stack
- The problem of large-scale TCP poisoning is treated: an attacker, who is able to monitor TCP packet headers in the network, can deny service to all flows traversing the monitoring point simply by injecting a single spoofed data or control packet into each of the flows. One of the entities...

- A Fluid Analysis of a Utility-Based Wireless Scheduling Policy
- This paper considers packet scheduling for the downlink in a wireless network, where each packet's service preferences are captured by a utility function that depends on the total delay incurred. The goal is to schedule packet transmissions to maximize the total utility. In this setting, the paper examines a simple...

- Firewall Strategies
- Security is a difficult job that involves constant care. Computer systems or other networked devices are vulnerable by virtue of their ability to connect and communicate with other systems. A firewall reduces some of the risk by reducing the number of devices that can communicate with a protected host. Purchasing...

- Pricing at the On-Ramp to the Internet: Price Indices for ISPs During the 1990s
- This paper estimates hedonic price indices for dial-up Internet Service Providers ("ISPs") in the United States from November 1993 to January 1999. This was a period of rapid qualitative improvement in Internet access. The paper shows that price indices without any quality adjustment hardly change after 1995, which the paper...
