RSS packetsDDoS: A Threat You Can't Afford to Ignore
White Paper Distributed denial of service, otherwise known as DDoS, refers to a form of attack whereby a number of source IPs simultaneously send an abnormally large number of packets to a particular destination, thereby... [05 Oct 2009]
Distributed Denial of Service (DDoS) Attacks: Latest Motivations and Methods
White Paper A Distributed Denial of Service (DDoS) attack aims to intentionally deprive legitimate users of a resource (or service) provided by a system, typically by overloading that system with a flood of data packets from... [05 Oct 2009]
Denial of Service Attacks in Networks With Tiny Buffers
White Paper Recently, several papers have studied the possibility of shrinking buffer sizes in Internet core routers to just a few dozen packets under certain constraints. If proven right, these results can open doors to building... [02 Oct 2009]
A Principle of a Data Synthesizer for Performance Test of Anti-DDOS Flood Attacks
White Paper Real events of DDOS flood attacks show that an attacked site (e.g.server) usually may not be overwhelmed immediately at the moment attack packets arrive at that site but sometime late. Distributed Denial-Of-Service... [02 Oct 2009]
Empirical Study of Tolerating Denial-of-Service Attacks With the Fosel Architecture
White Paper Experimental study shows that by employing the Fosel architecture, DoS attacks have a negligible chance to saturate the target by malicious packets. Filtering techniques are one of the main approaches to protect... [02 Oct 2009]
QoS: What Is It? Why Do We Need It?
White Paper Quality of Service (QoS) is the ability to treat packets differently as they transit a network device, based on the packet contents. Without QoS, all packets on the network vie for the same pool of... [01 Oct 2009]

Buffer Management for Colored Packets With Deadlines
White Paper The paper considers buffer management of unit packets with deadlines for a multi-port device with reconfiguration overhead. The goal is to maximize the throughput of the device, i.e.the number of packets... [16 Sep 2009]
CAFE: A Configurable PAcket Forwarding Engine for Data Center Networks
White Paper Through simple APIs, CAFE can be easily configured to forward self-defined packets, modify, insert, and delete arbitrary packet header fields without re-designing the hardware. Recently, Data Center Networking (DCN) has... [16 Sep 2009]
HP-UX IPFilter Version 16 Performance White Paper
White Paper IPFilter filters IP packets by reading the network protocol headers and comparing the values to a set of user-configured rules. Based on these rules, IPFilter either passes or drops the packet. Because IPFilter only... [30 Aug 2009]
Flexible Forward Error Correction Codes With Application to Partial Media Data Recovery
White Paper Conventionally, linear block codes designed for packet erasure correction are targeted to recover all the lost source packets per block, when the fraction of lost data is smaller than the redundancy overhead. [29 Aug 2009]
Cisco wireless LAN: At risk from 'skyjack' attack
News Someone out in the parking lot or a neighbour can look at the packets and see information about the controller on the wired side," he said. Cisco Systems wireless local area network equipment used by many corporations... [25 Aug 2009]
