1 COMPARATIVE ANALYSIS OF IPV4 & IPV6 IN CLOUD ENVIRONMENT FOR FTP & DATABASE SERVICES Mr. Ammar Rafique**, Mr. Muhammad Waqas Anwar, Mr. Haris Shabbir, Mr. Moazzam Ali Baig, Mr. Rohail Ayaz Computer Science Department NFC-IEFR Faisalabad, Punjab, Pakistan **Corresponding Author: Abstract: Cloud computing is a structure of services which provides its users the access to cloud servers through internet to hire as many services as he/she could. The main focus of this research is on the Internet Protocol versions IPv4 and IPv6. The cloud in computer networks is actually a setup of servers providing different services to the users via internet. In this regard Internet Protocol is back-bone of internet and cloud computing. Internet Protocol is necessary element to route data from a user to the servers of cloud through the internet. In this paper we compare these two internet protocols over the cloud. We will design a scenario on OPNET 14.5 to analyze the results. Keywords: Cloud Computing, IPv4, IPv6, cloud, OPNET Introduction A. CLOUD COMPUTING It's modern technology that provides user access to its servers through the Internet for its services. Cloud just gave us a chance to store our data online. From the definition offered by Cisco we assume the three types of cloud environment, 1) On-Demand: services are the services provided to users when they demand to hire them. 2) On-Scale: services are provided to users according to the payment done by or by the status of the user. For example if user is an organization then the scale of services will be different. 3) Multi-tenant: services are those services which can be allocated to more than one user at a time. B. CLOUD COMPUTING DEPLOYMENT MODELS Cloud computing can be categorized according to its deployment structures. Four main deployment structures or models are described as follows, 1) Public Cloud: is a kind of cloud in which applications are made generally accessible to the public. Clients are hence publically allowed to access and use the services all over the internet We have lots of examples in our real life scenario include Social Networking sites like Face-book, yahoo, Twitter etc. Public Cloud environment is most preferably applicable in those organizational scenarios where number of industries has same kind of needs. 2) Private Cloud: as the name indicates is generally designed for an individual or for personal use. Traditionally it is implemented by a single organization within its own circle. For example the cloud servers within an industry to provide cloud services to its own employees. 3) Community Cloud: Community cloud as its name shows is a set of services between two or more organizations to communicate and share data and programs between them. Let's take an example to explain this community cloud architecture. For example five universities connected with each other to share the computing resources are forming a community cloud. 4) Hybrid Cloud: By getting the mixture of services of public and private cloud the hybrid cloud is formed. In simple words when an organization shares some services on public channel and some on its own private channel then this architecture is called the hybrid cloud. C. SERVICE CLASSIFICATION Cloud computing division w.r.t services is given below, 1) Software as a Service (SaaS): The true meaning of the software as a service is to provide programs on the WWW as a Web service. So that the user can take advantage of the software in the internet browser without downloading and installing NFC-IEFR Journal of Engineering & Scientific Research 5

2 it. The most common examples of SaaS (software as a service) providers are Microsoft and Google 2) Platform as a Service (PaaS): Architecture brings the concept of customizable user platform to build their own applications required. Users do not need to panic about the hardware investment and maintenance expenses. The most common are the providers of PaaS and Windows Azure, Heroku, Force.com. 3) Infrastructure as a Service (IaaS): Infrastructure as a model service users to get more concessions from SaaS and PaaS architectures. The user can define and manage the hardware specifications of the apparatus default provided by the service provider cloud. Often used IAAS are going network and Amazon EC2 Protocol (communication protocol) is a pattern of rules that are applied. So that the device (such as a computer) can perform different functions, especially any communication with each other. Internet Protocol (IP) is the ruler of the Internet. When the hosts (computers) to establish a connection to the Internet, IP address is assigned to them individually. These data packets hosts exchange with each other to communicate with each other. These data packets contain the IP addresses of the source and destination hosts. When the host connects with the other host, it transmits a package with the IP addresses of the source and destination. Internet Protocol version 4 is the title of the 32-bit. It contains 4 octets or unique parts of four sentences, and the total number of IPv4 addresses are (232) = In 1990, the Internet Engineering Task Force saw that the new version of the IP would be needed. Has been the development of Internet Protocol Next Generation (IPng), which was later called Internet Protocol Version 6 IPv6 is a standard protocol layer 2 (WRT TCP / IP Model), which follows IPv4 addresses to communicate over the Internet and other networks. The size of the IPv6 address is 128 bits. we can write address in hexadecimal or binary codes. Therefore, the total number of IP addresses I P v 6 c a n p r o v i d e i s = e It's a large amount of addresses. I. LITERATURE REVIEW H. Zahid, A. Arshad, M. Khalid, B. Saeed and A. Rafique (2013) Descript that the technology, which provides us with a practical computing resources across the Internet all over the world and the socalled cloud computing. This paper covers security issues of DOS attacks on servers cloud by pirates or zombies. J. P. Sahlin, S. Sarkani and T. Mazzuchi (2012) said that there are two types of providers of cloud services, and one is the one that offers cloud services for the purpose of their business and other government institutions that do not want to make a profit from cloud services, but they want to keep the cost as low as possible. Even for both type of cloud service providers and effective way to learn how you can upgrade the system to take advantage and keep the cost without affecting the quality of service (QoS), is a tool OPNET. Gandotra, P. Abrol, P. Gupta, R. Uppal and S. Singh (2011) said that each author's definition of cloud computing is in their own words. Sometimes we feel the confusion which definition is correct. First of all, cloud computing is not a completely new concept it is triggered in 1998 when we started the grid computing and it is also associated with cluster computing. In this paper will be to discuss details about grid computing and cluster computing technology and the future of cloud computing. M. Cotton, L. Vegoda, R. Bonica & B. Haberman (2013) explained that the purpose of their paper is reset block of IPv /24 to IANA. This document is the imposition of IANA to rebuild their records for the purposes of private address of the IPv4 and IPv6. They said that this paper is a product of the Internet Engineering Task Force (IETF). It reflects the IETF community and allows publication by the Internet Engineering Group (IESG) leadership. Result in the publication of this document in the RFC (Request for Comments) No. 4773, and 5736 is no more in function. J. Touch (2013) Wrote that the work ID in IPv4 is to assist the process of breaking up and removing fragmentation during the transmission process. Other quality of this is that it must be different for each packet of data packets, and should retain its NFC-IEFR Journal of Engineering & Scientific Research 6

3 value for the maximum time. If he does so then transfer speed or links will be limited to 6.4 megabits per second. But the normal regulations reflect this limit. Therefore, the purpose of this document is to update No. RFC 791, 2003 and this update is to discuss with the viewpoint of the current use of near field ID addresses IPv4. G. Bhatia, A. Lala and A. Chaurasia (2012) extracted from that cloud computing is somewhat a combination of virtualization and distributed computing and utility computing. Add new networks and the Internet makes it more useful to end users. These days the user has no need to buy expensive computing devices. What he has to do is just to hire a cloud service. Indian Railways (the fourth-largest train system in the world), which carries 30 million humans and 2.8 million ton of luggage a day working at a loss. The reason for this loss is the black market for tickets by employees, passengers and overloading trains without tickets. This paper discusses how to implement cloud computing to solve all these problems, as well as Internet facility in trains. Designed scenario discussed in OPNET simulation. The structure is configured the same scenario all versions of IP (IPv4 and IPv6) to make a comparison between both versions of IP. Research scenario is shown in Figure 1 contains servers that provide cloud database, FTP, and video conferencing services to LAN networks connected to these servers through a network of routers. Each LAN contains 100 customers. All users in these local networks used all types of services. Figure 2 represents a summary of inventory scenario discussed in the design modeler OPNET The parameters we set to measure the performance of IPv4 and IPv6 on the same scenario question the response time of the database service, download the response time of the service FTP, download the response time for the FTP service and end-to-end packet delay for video conferencing service. 2. Research Work OPNET is best tool to do the modeling of networks. With the help of OPNET Modeler, we can judge and check all likelihood after a change in the structure of the network. Fig. 2: Network Inventory Summary 3. Results Analysis Fig. 1: Research Scenario Figure 3 is a graph that represents the query database shows the results of the response time of both scenarios IPv4 and IPv6. It shows that IPv4 is fast in NFC-IEFR Journal of Engineering & Scientific Research 7

4 service to query the database cloud version of IPv6. Figures 4 and 5 show the results of FTP download and upload response times, respectively. IPv6 has demonstrated a delay in responses to a smaller number of cases of IPv4 addresses and IPv4, but the delay was much less of IPv6 on those cases. Graph in Figure 6 describes the end-to-end delay through video conferencing. IPv6 has again put more time delay of IPv4, but in a smaller number of cases. Figure 5: FTP Upload Response Time Figure 3: DB Query Response Time Figure 6: Video Conference End to End Delay 4. Conclusion Figure 4: FTP Download Response Time Considering the simulation, we got graphical results, it is concluded that even if IPv6 is a newer version of IPv4 has advanced features than IPv4, but the larger size of the header caused the delay in the transmission and bulk traffic, such as video conferences delay is much larger than the delay IPv4. So if IPv4 replaced by IPv6 (for cloud services), the first threat that we face is greater delay NFC-IEFR Journal of Engineering & Scientific Research 8
