Denial Of Service Tuning For Cisco IOS Software Firewall And Intrusion Prevention System
White Papers Cisco IOS Firewall also regards User Datagram Protocol (UDP) sessions with traffic in only one direction as "Half-open", as nearly all applications that use UDP for transport will acknowledge reception of data.

Performance Of Constant Quality Video Applications Using The DCCP Transport Protocol
White Papers The Datagram Congestion Control Protocol (DCCP) is a transport protocol that was developed by the IETF to provide an unreliable congestion controlled delivery of data packets. It removes the shortcomings of TCP and UDP for real-time applications...

Transport Control Protocol
White Papers TCP (Transmission Control Protocol) implements a reliable data-stream protocol, whereas UDP (User Datagram Protocol) implements an unreliable data-stream protocol. IP provides a connectionless datagram service between two computers.

Steady State And Transient State Analyses Of TCP And TCP-Friendly Rate Control Mechanism Using A Control Theoretic Approach
White Papers A real-time application traditionally uses either UDP (User Datagram Protocol) or TCP (Transmission Control Protocol) as its transport layer protocol. However, using either UDP or TCP is insufficient for most real-time applications because of...

TCP Streaming For Low-Delay Wireless Video
White Papers Traditionally, UDP (User Datagram Protocol) is used for video streaming. Furthermore, UDP streams are often more difficult to penetrate firewalls. Hence the paper proposes using TCP (Transmission Control Protocol) for video streaming in this paper...

Firewall-Friendly VoIP Secure Gateway And VoIP Security Issues
White Papers This is because typical intranets are protected by firewalls and IP telephony protocols are not firewall-friendly - because, among other reasons, they use UDP (User Datagram Protocol)-based protocols.

Teredo Overview
White Papers To traverse IPv4 NATs, IPv6 packets are sent as IPv4-based User Datagram Protocol (UDP) messages. Teredo, also known as IPv4 network address translator (NAT) traversal for IPv6, is an IPv6 transition technology that provides address assignment and...

Learn To Detect And Prevent Hacking Reconnaissance
White Papers The goal of reconnaissance is to discover the following information:IP addresses of hosts on a target networkAccessible User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) ports on target systemsOperating systems on target...

Hybrid TCP-UDP Transport For Web Traffic
White Papers The scheme uses either TCP, or the User Datagram Protocol (UDP) as the underlying transport protocol for carrying web traffic. Most of the web traffic today uses the HyperText Transfer Protocol (HTTP), with Transmission Control Protocol (TCP) as...

SYSLOG Enhancements For Cisco IOS EasyVPN Server
White Papers Syslog uses User Datagram Protocol (UDP) as the underlying transport mechanism, so the data packets are unsequenced and unacknowledged. The syslog messages discussed in this paper can easily be logged from a Cisco IOS EasyVPN server to an external...

Game Server Flaw Poses Attack Threat
News The problem takes advantage of Internet data known as the user datagram protocol, or UDP. Unlike the more common transmission control protocol, or TCP, packets that make up the majority of Internet traffic, UDP data doesn't require a connection to...

Deconstructing Denial Of Service Attacks
News Here's what happens: an attacking machine generates what appear to be normal messages, such as the User Datagram Protocol (UDP) packets. In the case of a UDP D.O.S.attack, these packets claim to come from the same server that's receiving them.

CERT Casts Doubt On Security Find
News He said the program sent large quantities of fragmented data using a standard known as the User Datagram Protocol (UDP). He disputed the notion that the problems witnessed by the small circle of testers could be an old UDP issue.
