Executive summery

In now a day’s internet is the best way to communicate with each other. The born of internet is happens the operation of the packet switching network.

In this scenario we are mainly focus on the how and why the engineers created TCP/IP, how this TCP/IP changed, why engineers created TCP/IPv6 and what has happen to date to

actually implemented TCP/IP6.

We can consider this the TCP/IP protocol system is the big step of success of internet and

TCP/IP. In these days we use TCP/IPv4 to connect internet. But people’s needs are grows up then

engineers are looking for solution. Then engineers think about the newer version TCP/IP. We call this newer version of TCP/IP as TCP/IP version 6. This whole document is focus on IP and its beyond

Introduction

Background

The main aim of this report is describing the IP and beyond. First we need to know what the internet is. Internet is a connection which need communicate with each other. In today’s internet is the greatest achievement of our time in data communication. Internet using special address for connects the global network. We call this common address is TCP/IPv4. Most people don’t know them using this protocol to connect the internet. In this report we are mainly focus on the 4 categories. This categories are how is TCP/IP created and how is become dominant network, evolution of the TCP/IP, birth of the TCP/IPv6 and resulting impact. First category is use to describe about how TCP/IP created and also going to describe about how is become dominant network. Second category is use to describe changes happen on the TCP/IP, what thing are add to it and also going to describe about crisis of the TCP/IP. After describe about current version of TCP/IP and then I move to describe about how TCP/IPv6 created and thing we must consider the TCP/IPv6 creating. At the last I am going to describe about how long ago this crisis foreseen and what happen the day that actually implemented TCP/IPv6.

Scope

In the todays we use internet to connect all over the world. And internet is use special address for connect all over world. This special we call is TCP/IP address. This report is providing good details for the users who use the internet and like learn about the IP.

TCP/IP

People refer the TCP/IP protocol as communication protocol for data transport. The main

purpose of the creation of TCP/IP is users to connect to the internet.

Most computer users don’t know they using TCP/IP to connect what they call web. And

those users don’t know difference between internet and web. Web is application of the internet.And network engineers created web for provide internet to data flow between client and server. I mention that TCP/IP is communication protocol. But we don't what is the communicationprotocol. Network engineers refer communication protocol is set of regulation use by networkto communicate. In simple word this means the communication protocol is use some kind oflanguage to communicate with each other. This common language used in the network is TCP/IPprotocol language. This TCP/IP is design in the result of the united states defense departmentadvanced research project agency. That means this protocol history begins with US defensedepartment visionary soldiers of advanced research project agency. This solders created thisprotocol for US defense system security. Because some kind of vulnerable failure happen on thenetwork then whole network going down. After few years later the national science foundationbuilds the network with ARPnet's. That network which we called today is internet. The TCP/IPprotocol is Hugh step of success of internet and TCP/IP.

In the early days in America everyone had some type of WANG machine. But 1980’s and

early 1990’s Novell NetWare application implemented every office. TCP/IP protocol andNetscape’s navigator, internet explorer and web programming language working together andProduce cooperate network which is called intranet. Intranet is simply network which is use toConnect different site and companies can communicate with each other through the internet.Somebody want to buy something in the intranet they can access cooperate intranets usingextranets. That’s means someone want to purchase something into the internet they can usedirectory service which using through Domain name service.

And another key factor type of the TCP/IP extensibility. TCP/IP will allow users to move

their workstation across any part of the network. And the best thing available for the TCP/IP isTCP/IP portable feature. These portable features are TCP/IP can runs on the different operatingsystem and addressing is handled on a global assignment. Best one of the thing available for theTCP/IP is supporting for Novell. That means TCP/IP support Novell by native IP andintraNetWare. TCP/IP becomes more common because the Microsoft NT platforms are also usingTCP/IP protocol. However TCP/IP become very popular because TCP/IP protocol schemes areexistence, provide many benefit and continue to be used for years to come.

We call TCP/IP network is heterogeneous network. That means they are many different type

of Computing device attached. There are few reason why TCP/IP become more popular in early days. It’s been popular after the American college student using operating system which callBerkeley operating systems are using the TCP/IP. Also 1980’s all government proposal requiredTCP/IP. And TCP/IP protocol is using web graphical user interface. In the world it’s Popular after it’s ingenious ability to work on any operating platform and easy remote access Capabilities.

Network engineers select TCP/IP is a there dominant network because TCP/IP protocol included several features. This several features are logical addressing, routing, name service, application support. TCP/IP logical address is for using capabilities with sub netting. Also this logical address is some kind of network software. We call this logical address is IP address. The routing feature is used for reading the logical addressing and direct data across the network. The name resolution service is used for process to accept the name for a computer from a user and resolved the corresponding IP. The error checking capabilities of the TCP/IP is providing best reliable data service across the network. Application support means this TCP/IP is us protocol software like web to gain access the network. TCP/IP becomes the dominant network protocol by using this several features today.

Evolution of TCP/IP

In the last few years several changes happens on the TCP/IP. That mean engineers added many thing to the TCP/IP. Engineers also added several extensions to IP layer and TCP. We can mention this extension Internet Control Message Protocol (ICMP), Internet Group Management Protocol (IGMP), resource reservation protocol. Internet control message is use to report a certain condition on the network and it’s provide error reporting for the IP. Internet group management is allowing for multicast to operate on internetwork and allow host to identify the group which needed to the router. The IGMP header is used basis for every multicast routing protocol tor IPv4. Resource reservation is providing quality of service on an IP internet. We can mention that TCP/IP is running over the LAN. ARP is only protocol that translates 32 bit address to the 48 bit address in the Local Area Network. Other related protocol of the ARP is Reverse Address Resolution Protocol (RARP). RARP protocol used only on a LAN and it’s not involved the IP

After TCP/IP implemented few years later several protocol are added to the TCP. These protocols are Real Time Protocol (RTP), Real Time Control Protocol (RTCP) and those protocols are framework protocol and this protocol stay on the transport layer and work alongside with TCP. Engineers are also developing the TCP/IP standard application. These standard applications are Telnet, FTP, TFTP, SMTP, DNS, and BOOTP/DHCP. When looking at the telnet its works on the top TCP and provide remote terminal emulation. Remote terminal emulation is mean by it allow network workstation just appear as a local device to remote device. File Transfer protocol (FTP) is also similar to the TELNET and it’s also works on the top the TCP. This protocol is use to transfer data files on the internet. Simple Mail Transfer Protocol (SMTP) is use to exchange electronic mail between two or more system by using internet. Domain Name Service (DNS) is used to provide name service. Its mean by DNS provide name to network address translation service. The Boot Protocol (BOOT) and Dynamic Host Configuration Protocol (DHCP) provide TCP/IP for management of the IP parameter.

RFC 950 introduces sub netting after introducing the RFC 760 which is introducing IP. The sub netting allow for efficiency with class address. There is little reason why engineers created sub netting. These reasons are most IP address assignments are not used efficiently, most sits are requesting multiple network numbers, every network are adopt to use proprietary subnets.

In the 90’s the explosion of connectivity to internet started when IPv4 is running out of address. The range of the TCP/IPv4 address is 32 bit in length. That is allowed for 4,294,967,296 unique addresses. But problem is occurs when address are group in the class address. That means lots of wasted happens a range of bits applied to the address. But the original problem is happen when the three type of classful and address is also allocation without plan. That means address was arbitrarily handed out without showing the location. The class A address is stopped handed out and class B is exhausted and class c overtaxing the internet routing table. In later RFC 1338 is introducing the idea of suppernetting. Supernetting is used for summarized multiple network numbers and it turned into a Classless Inter Domain Routing (CIDR). The last thing is discuss about the evolution of TCP/IP is what is the crisis of the TCP/IP.

Birth of TCP/IPv6

TCP/IP is changed over last few years. Then network engineers are now also talk about the new generation of TCP/IP which is called TCP/IP version 6. There is problem happens on the previous IP version 4. Because the problem is occurs world running out of address and IP address fall within the address class. TCP/IP version 6 research and development start at early 90’s. Also today’s internet is large and commercial then implemented of the TCP/IP version 6 is the biggest problem now. Intoday’s world engineers are studied to determine IP version 6 addressing allocation, effect of IP version 6 on IP version 4, tunneling, and many things. But before implemented IP version 6 engineers need to commercial the IPv6 and create a new application which can works on the IPv6. There another IP version between IPv4 and IPv6 it’s called IP version 5. It is known as Internet Stream Protocol (ST2) and it is defined by the RFC 1819.

We can consider TCP/IPv6 needs a dynamic environment before implementing TCP/IPv6. On dynamic environment TCP/IPv6 included many discover option. This discovers options are called auto configuration, finding maximum path MTU, finding other work station without address resolution protocol and finding the router. The current version of IP version 4 address size is 32bits but size new version IP version 6 addresses size is 128bits. Then network cannot run out of address. Because the size IPv6 address is very large.

We consider the features network engineers are said about when TCP/IPv6 created. These features are extended address capabilities, header format simplication and improved support for extension and option, flow level capabilities, authentication and privacy capabilities. Expanding addressing capabilities that mean its support and also improved IP address auto configuration capabilities and also given a new brand new address which we call anycast address, IPv6 has a Simple header format, Improved support for extension and option that means store some header information in the IPv6 optional header.Flow labeling that means IPv6can mark datagram for specific flow level, improved support for authentication and privacy.

We must know what the type of the IPv6 header when engineers created TCP/IPv6. The size of IPv6 header is can be 40 octets. And IPv6 header contains 16 octets for source and 16 octets for destination.Engineers mention that there are several fields are included for IPv6 header.That’s fields are Version (4 bit) it is used to identify the IP version number, priority (4 bit) is use to identify priority setting, Flow label (16 bit) is used to designates the flow level, payload length (16 bit) used to assign the length of data, Next header (8 bit) is used to identify the type of header, hop limit (8 bit) show remaining hops which is for datagram, source address(128bit) to identify the address of the source computer, destination address(128bit) identify the address of the destination computer.Engineers also said about IPv6 extension headers. And they define extension headers as provide information in specific situation.These extension headers are routing header, destination option header, fragment header, no next header, authentication header, hop by hop options header, Encrypted security payload header. Destination option header is used for carrying important information that need to examined packets in the destination nodes.Fragment header store important information for reassembling fragmented datagram.Authentication header use to provide security and also providing authentication information for IP datagram. Routing header is used for identify intermediate routers in IPv6 datagram.Hop by hop option header used to carry additional information which needs to intermediary nodes along with packets delivery.

Engineers also consider abouttransporting IPv6 packets using IPv4 routing topologies creating TCP/IPv6.that is called tunneling.There are four type of tunneling methods. Tunneling methods are host to router, router to router, router to host and host to host. When looking at first two, it use endpoint as intermediary router and decapsulated IPv6 packets and transfer this packets to its final destination. Then looking at last two, it use automatic tunneling to the destination.

Someday an engineer created TCP/IPv6 it can be coexisting with the TCP/IPv4.birth of the TCP/IPv6 is the big step of success the TCP/IP and future of the internet.

Resulting Impact

The crisis foreseen of TCP/IP is happen late 1980’s. It’s happening TCP/IP version 4 is running out of address. Then engineers think about new version IP in early 90’s and they started develop it since early 90’s. The current version of TCP/IPv4 has few changes during the last 20 years. During this time they changed lot of things in the TCP/IPv4. There is a changed happen on the TCP/IPv4 method of employing 32 bit addressing. But the addressing is not changed during this method. Now in today’s world people needs are grown and use of the internet is also grown because todays we living in the digital world. Then resources are not enough to provide their needs. That is also why TCP/IPv4 is not enough handle this situation. Then network engineers are also thinks about the new version of IPs and other type protocols. But other type protocol such as Appletalk, SNA, Decnet and many others are not a good solution in this case and also lots of this are out of use today. Now then engineers are talk about the new version IP that is called IPv6. IPv6 is appeared the result of shortage address space of the IPv4. And that mean it’s not a replacement of the TCP/IPv4. Also that mean crisis foreseen is not stopped after implemented in TCP/IPv6. But in the future TCP/IPv6 is good exception for the people.

There are several proposal are presented and experimented before presenting the TCP/IPv6.

Proposal we can mention as lot of support want to replace IP with ISO OSI (International Organization for Standardization) CLNP protocol. ISO CLNP is experimented as TCP and UDP over Bigger Address.

Several changes to the TCP/ IP layer, TP/IX placement evolved into the CATNIP

IP in IP evolved into IP Address Encapsulated, it’s used to works on two layer of the IP protocol.one layer for the worldwide backbone and layer for regional IP networks.

In 1992 and 1993 bleacher develop protocol is used to candidate replacement for IP. It’s called PIP internet protocol and it merge with the Simple Internet Protocol (SIP)

SIPP (SIP Plus) is evolutionary step from IPv4 and it can installed as a normal software and use to modify the internet devices and is interoperable with the current IPv4.

People are not adopted to using TCP/IPv6. Because capabilities requirement for TCP/IP version 6 is higher than we think it’s can’t runs on the low power router and lower power pc. The implemented of the TCP/IPv6 need dynamic environment. The implemented TCP/IPv6 over TCP/IPv4 is more complicated than we think and also its not be easy to implement. Today’s current version of IP is enough then people didn’t want new version IP. In the world 99 percent of all networks are using TCP/IPv4 that means implemented TCP/IPv6 is very hard and then 50 percent of people are not hearing about the TCP/IPv6. In implemented IPv6 before engineers need to create application that can run on the TCP/IPv6. But creation of the application is more hard and very complicated then also implemented of the TCP/IPv6 is going to be an imagination. ISP is also not adopted to using TCP/IPv6. Because implemented and connection of the TCP/IPv6 is more sophisticated.

The day TCP/IPv6 is actually implemented. But Most like today IP address also handed out with the Internet Service Provider (ISP). The direct connection to the internet is not allowed. That means we can connect internet through ISP. ISP is use most common address format fortheir connection. The first 3bits is use to identify the address as a provider oriented unicast address. The register ID identifies internet address registry, APNIC is use to assign provider identifiers which stay at provider ID,The subscriber ID allow to identify multiple subscribers attached to the internet service provider which use to identified by the provider ID.The subnet ID is use to identify the specific physical link.The interface ID is use to identifythe single interface during the group of interfaces identified by the subnet prefix.

We need to consider about day that TCP/IPv6 is really implemented. First we need to look at how IPv6 addressing are using by local use. In the local use there are two type addresses. First type of address is link local address. This address we can use by between two stations on a single network. And this addressis not be processed by router. This address is use the reserved prefix format of FE. The second type of address is site local address. This IPv6 site local address will allow site to configure their network by without connecting the internet. It’s not like a IPv4.

That means this site local address will allow your site to communicate with all interfaces at the site. And this site local address not is routed over the internet.This address is also use the reserved prefix format of FE.

There is something happen on the TCP/IPv4 when implemented in TCP/IPv6.beacuse TCP/IPv4 address is going to be an embedded after TCP/IPv6 implemented. The transaction strategy will allow for move IPv4 to IPv6. Someday its actually implemented TCP/IPv6 can be coexist with TCP/IPv4. In this day engineers also said TCP/IPv6 is another step of success the future of the internet.

Conclusion

The topic of this report is To IP and beyond. But main aim of this report is divided into 4 categories. The 4 categories we mention in this report is background of the TCP/IP, evolution of the TCP/IP, birth of the TCP/IPv6 and result impact.

The first category is discuss about how TCP/IP created, how did TCP/IP implemented, and why did the TCP/IP become the dominant network protocol. And also this category is described about features in the current version of TVP/IPv4. Second category is use to describe about what changes happen in the last few years, what thing are added during the last few years and crisis of the TCP/IPv4. The third category is describe about why was engineers think about TCP/IPv6 and why they created it and what things were consider when TCP/IPv6 creation. The last category is described about how long ago this crisis foreseen happen and why hasn’t TCP/IPv6 adopted and what happened date actually implemented TCP/IPv6.

The common communication network which we called today is a internet is also using the TCP/IP for communicate with each other. When there is a problem happens on the address. Because people needs are grown and use of internet is also grown. And then engineers think about new version IP which we called IPv6. TCP/IPv6 is the big step of success TCP/IP and future of the internet. Someday engineers implemented IPv6 it can coexist with the IPv4.

Glossary

Authentication: The positive identification of a network entity such as a server, a client, or a user.

DHCP (Dynamic Host Configuration): A protocol that computers use to obtain configuration information. DHCP allows a computer to be assigned an IP address without requiring a manager to configure information about the computer in server’s database.

DNS: Domain Name System is an internet names translator to a human-readable computer hostnames. It allows using unique alphabetical addresses instead of numeric ones and more easily find and communicate with web sites and other server-based services.

IP address: A 32-bit address assigned to a computer that uses TCP/IP protocols. The sender must know the IP address of the destination computer before sending a packets.

IP: The protocol that define both the format of packet used on a TCP/IP internet and the mechanism for routing a packet to its destination

ISP: A commercial organization that provide its subscribers with access to the internet.

LAN: Local Area Network is a computer network that located in specific geographic area. It is commonly comprised of several computers that connected through network switch or hub to exchange data between them.

Protocol: A design that specifies the details of how computers interact, including the format of messages they exchange and how error are handled.

Router: The basic building block of an internet. A router is a computer that attached to or more network and forward packets according to information found in its routing table.

SMTP: Simple Mail Transfer Protocol is a standard for e-mail transmissions. It is include with one or more recipients and a message that transferred to a remote server using client and server queries and responses.
