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 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

Abstract
The objective of DRUG DELIVERY USING NANOTECHNOLOGY is to explore the areas which are not accessible to human beings without any surgeries This paper discusses about the ways by which drugs were delivered using Nano technology. The general approach of drug delivery using nanotechnology is to attach the drug to a nano sized carrier that will release the medicine in the body over an extended period of time or when specifically triggered to do so. Medical applications of nanotechnology may sound like science fiction, but theyâ„ ....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

ABSTRACT
DELAY TOLERANT NETWORKING
Increasingly, network applications must communicate with counterparts across disparate networking environments characterized by significantly different sets of physical and operational constraints; wide variations in transmission latency are particularly troublesome. The proposed Interplanetary Internet which must encompass both terrestrial and interplanetary links is an extreme case. An architecture based on a least common denominator protocol that can operate successfully and (where re ....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

ABSTRACT
Content Delivery Networks (CDN) is evolved in first 1998 as a technique for improving the web performance by replicating web contents over several Surrogate Servers (Mirrored servers) strategically place at various locations to deal with the flash crowds. A set of surrogate servers distributed around the world can cache the origin serverâ„¢s content. Routers and network elements that deliver content requests to the optimal location and the optimal surrogate server. Under CDN, the client-server communication is repla ....etc

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
