Volumetric DDoS attack sizes peaked at 54 Gbps/18 million packets per second (Mpps) for User Datagram Protocol
(UDP) floods and 8 Gbps/22 Mpps for Transmission Control Protocol (TCP)-based attacks.
To address this problem, Fujitsu Laboratories has succeeded at a software-only approach, developing: 1) A new protocol that incorporates an efficient proprietarily developed retransmission method based on user datagram protocol
(UDP)(2), an optimized way to deliver streaming media able to reduce latency resulting from data retransmission when packet loss occurs; 2) Control technology that addresses the problem of UDP transmissions consuming excess bandwidth by performing a real-time measurement of available network bandwidth and securing an optimal amount of communications bandwidth without overwhelming TCP's share of the bandwidth; and 3) Technology that, by employing the new protocol, makes it possible to easily speed up existing TCP applications without having to modify them.
Internet Protocol (IP), User Datagram Protocol
(UDP), and Transmission Control Protocol (TCP) are basic standards for the network communication.
This paper presents a simple Matlab Simulink implementation of a communication system, based on Matlab's ability to interact with external programming languages, using MELP (Mixed-Excitation Linear Predictive) 2400bps vocoder for good audio quality at a low bit rate, AES (Advanced Encryption Standard) encryption in ECB (Electronic Code Book) Mode for communication security and User Datagram Protocol
(UDP) protocol for voice communications.
User datagram protocol
(UDP) is another option for layer 4 transport.
The ability to process applications reliant on user datagram protocol
(UDP) enables SSL 4.
Port--(Integer input parameter)--In computer networking, a port is an application-specific or process-specific software construct serving as a communications endpoint used by Transport Layer protocols of the Internet Protocol Suite such as Transmission Control Protocol (TCP) or User Datagram Protocol
WAP is based on the connection-less user datagram protocol
(UDP) and is designed to maintain the connection with minimal signaling traffic.
While WAP uses IP as its transport layer, it also uses the User Datagram Protocol
(UDP) instead of TCP, and it uses the new WTP (Wireless Transaction Protocol) at the transaction layer.
In this way, it determines what content is being requested and routes TCP or user datagram protocol
(UDP) flows to targeted servers based on the requested content.
At Layer 3, IP Multicast uses the User Datagram Protocol
(UDP) as its transport.
Advanced by the OASIS Web Services Discovery and Web Services Devices Profile (WS-DD) Technical Committee, these new standards include Web Services Dynamic Discovery (WS-Discovery), SOAP Over User Datagram Protocol
(UDP), and Devices Profile for Web Services (DPWS).
