RSS packetsTCPR: A Protocol for Handling Out of Order Packets in Satellite Networks
White Paper Reordering and corruption of packets decrease the TCP performance of a network, mainly because it leads to overestimation of the congestion in the network. The paper considers satellite networks and analyzes the performance of such networks when... [19 Dec 2007]
Detecting Distributed Denial-of-Service Attacks by Analyzing TCP SYN Packets Statistically
White Paper One of the problems in detecting SYN Flood traffic is that server nodes or firewalls cannot distinguish the SYN packets of normal TCP connections from those of SYN Flood attack. Distributed denial-of-service attacks on public servers have recently... [14 Jan 2008]
Deep Packets: Application Layer Security Threats
White Paper Viruses can sometimes go undetected through traditional firewalls, which typically scan only the headers of packets - the envelopes - and ignore the payload. What is needed is application layer filtering software, such as Microsoft Internet... [16 Jul 2004]
Matching TCP/IP Packets to Detect Stepping-Stone Intrusion
White Paper The paper propose a conservative and a greedy matching algorithm to match TCP/IP packets in real-time. The first algorithm matches fewer packets but the quality of the matching is high. The second one matches more packets with some uncertainty on... [05 Dec 2007]
Cisco Security Advisory: Cisco IOS Interface Blocked by IPv4 Packets
White Paper Cisco routers and switches running Cisco IOS software and configured to process Internet Protocol version 4 (IPv4) packets are vulnerable to a Denial of Service (DoS) attack. Multiple IPv4 packets with specific protocol fields sent directly to the... [07 Oct 2004]
Performance Improvement of TCP Over an Ad Hoc Network by Combining of Data and ACK Packets
White Paper When transmitting packets using TCP, data and ACK packets are transmitted in opposite directions on the same radio channel. To reduce the likelihood of packet collisions when an intermediate node transmits both data and ACK packets, these two types... [14 Jan 2008]
Measurement and Classification of Out-of-Sequence Packets in a Tier-1 IP Backbone
White Paper An important characteristic of any TCP connection is the sequencing of packets within that connection. Conversely, out-of-sequence packets indicate that the connection suffers from loss, duplication or reordering. [04 Jul 2007]
An Efficient Scheme for Accommodating Synchronous Traffic in a Cable-Modem Network While Avoiding Segmentation of Asynchronous Packets
White Paper The paper proposes an efficient scheme for combining asynchronous and synchronous traffic on the upstream channel of a CM network when segmentation of the asynchronous packets is to be avoided. Cable-modem (CM) technology is being developed to... [06 May 2004]
Sending IPv6 Packets to Check Firewall Rules
White Paper Network testing requires two simple components : a tool to send network packets, and a sniffer to intercept and display them. Most sniffers already recognize IPv6 packets (Ethereal, tcpdump, etc. This paper describes netwox toolbox, which can be... [26 Oct 2004]
Improvement of TCP Throughput by Combination of Data and ACK Packets in Ad Hoc Networks
White Paper In case of transmitting packets especially using TCP, data and ACK packets are transmitted in opposite directions on the same radio channel. To reduce the likelihood of packet collisions when an intermediate node transmits both data and ACK packets... [14 Jan 2008]
Efficient Scheme for Accommodating Synchronous Traffic in a Cable-Modem Network While Avoiding Segmentation of Asynchronous Packets
White Paper The paper proposes an efficient scheme for combining asynchronous and synchronous traffic on the upstream channel of a CM network when segmentation of the asynchronous packets is to be avoided. Cable-modem (CM) technology is being developed to... [24 Feb 2004]
Matching TCP Packets and Its Application to the Detection of Long Connection Chains on the Internet
White Paper The Roundtrip Times of these matched packets can be used to determine the number of intermediate hosts. Network attackers usually use long connection chains to hide their identity. One way to stop such attacks is to prevent the attackers from using... [14 Jan 2008]
Tracing Anonymous Packets to Their Approximate Source
White Paper Most denial-of-service attacks are characterized by a flood of packets with random, apparently valid source addresses. These addresses are spoofed, created by a malicious program running on an unknown host, and carried by packets that bear no clues... [24 Feb 2004]
Detection of Promiscuous Nodes Using ARP Packets
White Paper The documentation below discusses the use of Address Resolution Protocol (ARP) packets to effectively detect malicious users when they are sniffing the network. In the local network, the act of sniffing has become a serious threat. [24 Feb 2004]
Delay Analysis for Bluetooth Baseband ACL Packets
White Paper The delay for Bluetooth Baseband ACL packets is investigated in this paper. By including the effect of bit errors, a systematic analysis is carried out, which leads to the derivation of a new and precise delay equation for six different Baseband... [10 Nov 2005]
