ABSTRACT

Optical packet switching promises to bring the flexibility and efficiency of Internet to transparent optical networking with bit rate extending beyond that currently available with electronic router technologies. New optical signal processing have been demonstrated that enable routing at bit rates from 10gb/s to beyond 40gb/s.in this article we review these signal processing techniques and how all optical wavelength converters technology can be used to implement packet switching functions.

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 version of the IPV4 pro ....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

Optical Packet Switching Network

With in today's Internet data is transported using wavelength division multiplexed (WDM) optical fiber transmission system that carry 32-80 wavelengths modulated at 2.5gb/s and 10gb/s per wavelength. Today's largest routers and electronic switching systems need to handle close to 1tb/s to redirect incoming data from deployed WDM links. Mean while next generation commercial systems will be capable of single fiber transmission supporting hundreds of wavelength at 10Gb/s and world experime ....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

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 of t ....etc
