a new Internet Protocol is well understood and accepted in the networking industry. Requirements for more address space, simpler address design and handling at the IP layer, better QoS( Quality of service) support, greater security, and an increasing number of media types and Internet-capable devices have all contributed to drive the development of Internet Protocol version 6 (IPv6). IPv4, the current version of the Internet Protocol deployed worldwide, has proven remarkably robust, easy to implement, and int ....etc

MOBILE IP



Abstract


Mobile IP is a proposed standard protocol that builds on the Internet Protocol by making mobility transparent to applications and higher level protocols like TCP. Mobile IP (RFC 2002) is a standard proposed by a working group within the Internet Engineering Task Force; it allows the mobile node to use two IP addresses: a fixed home address and a care-of address that changes at each new point of attachment. The study describes how Mobile IP will change with IP version 6, the product of a major effort within the IE ....etc

ABSTRACT
Internet Protocol version 4 uses a 32 bit IP address. In theory ,a 32 bit address space should provide addresses for more than four billion computers, but inefficiencies in address allocation mean that less than half of the addresses are used. The result is so called-'Mnternet address crisis-there! are more computers than usable addresses Therefore permanent IP addresses have become expensive. There are two solutions to the problem .One is a long term solution of using IPv6,and the other is a short -time practic ....etc

CRYPTOGRAPHY AND NETWORK SECURITY
Abstract
Network security is a complicated subject, historically only tackled by
well-trained and experienced experts. However, as more and more people
become wired'', an increasing number of people need to understand the
basics of security in a networked world. This document was written with
the basic computer user and information systems manager in mind,
explaining the concepts needed to read through the hype in the
marketplace and understand risks and how to dea ....etc

The need...
 In CERTs 2001 annual report it listed 52,000 security incidents
 the most serious involving:
 IP spoofing
 intruders creating packets with false address then taking advantages of OS exploits
 eavesdropping and sniffing
 attackers listen for userids and passwords and then just walk into target systems
 as a result the IAB included authentication and encryption in the next generation IP (IPv6)

ABSTRACT
Virtual Private Networks is a concept introduced to implement global Wide Area Network(WAN) on the Internet. This way enormous costs involved in the traditional implementation of these networks i.e. through dedicated lines or satellite links is reduced considerably. A way to maintain fast, secure and reliable communications is attained wherever the offices are.

In the VPN, Internet is used as the data pipelined replacing the traditional datalines. This approach is just right for small and medium sized busines ....etc

Variants of Military Communications
ABSTRACT

In present world as the methods of warfare is changing along with it communications are also changing to stay in contact with the military units fighting scattered all over the world. In this paper we will discus the different possibilities for military communications and their pros and cons in war or war-like environment.
1)INTRODUCTION

If we study the history of conflicts we will see that in early days emphasis was made on the number of soldiers in an army, larger the army more effectively ....etc
