Datagram Congestion Control Protocol (DCCP)
Abstract
Fast-growing Internet applications like streaming media and telephony prefer timeliness to reliability, making TCP a poor fit. Unfortunately, UDP, the natural alternative, lacks con- gestion control. High-bandwidth UDP applications must im- plement congestion control themselvesa difficult taskor risk rendering congested networks unusable. We set out to ease the safe deploymentofthese applicationsbydesigninga congestion-controlledunreliable transport protocol. The out- come, the Data ....etc

Datagram delivery and routing service to higher layer protocols are the functions of DDP. DDP frame headers can use Short format headers which carry only the source and destination service socket numbers, or the long format DDP headers also carry the source and destination network and node addresses needed for routing capability. AppleTalk Phase 2 supports only the long format DDP header for Phas as it does not use LLAP to identify source and destination nodes. ....etc

Almost all internet applications like the streaming media and internet telephone favour reliability than time. This factor makes the TCP factor a less preferred choice. Even the UDP network cannot make up to this level as it is in short of the congestion control. These congested controlled networks are usually causes great risk factors for the use of high bandwidth UDP applications. So naturally there was need for designing a congestion-controlled unreliable transport protocol. The result, Data gram Congestion Control Protocol or DCCP gets adde ....etc

Analysis of Datagram Congestion Control Protocol


ABSTRACT
In the last decade, there has been an enormous increase in the need to stream line data. Some of the primary applications like Voice over IP, Video Conferencing, music, and video streaming etc, need continuous flow, and transmission in real time, and consume a large amount of bandwidth. Data streaming usually employs one o ....etc

Datagram:



Packets in the IPV4 layer are called datagrams .
A datagram is a variable length packet consisting of two parts. These are
• Header
• Data
The header is 20 to 60 bytes and contains information i.e essential for routing and delivery and the header is represented in 4-byte sections. These are
1. Version
2. Header length
3. Service
4. Total length

1. Version(VER):
This 4-bit field defines the ....etc

USER DATAGRAM PROTOCOL


Introduction


The Internet protocol suite supports a connectionless transport protocol, UDP (User Datagram Protocol).

UDP provides a way for applications to send encapsulated IP datagrams and send them without having to establish a connection.

The UDP Header

UDP transmits segments consisting of an 8-byte header followed by the payload.

The two ports serve to identify the end points within the source and d ....etc
