IPv6 is a network layer protocol that functioned to the multiple IP-based networks during data transmission. It can be used to identify devices on the internet and thus locate them since IPv6 is the latest version of Internet Protocol. Internet communication on any device requires a unique IP address. Simulators play a significant role in any research project. We are supporting research in IPv6 simulation projects. Through this article, you will get a detailed overview of the IPv6 simulator.

We have created successful projects in IPV6 simulation throughout the world. So you get a chance to connect yourself with our world-class authorized engineers to make your project successful.

Go through the following article to get a complete understanding of research in IPV6 simulator projects.

Usages of IPv6 

The following are the major usages.

• Using IPv6 can improve performance, increase security, and handle packets more efficiently. 
• Network address translation (NAT) and IPv6 enable a corporate device with a secret IP address to communicate with a public IP address on the outside of the private network.
• By providing more TCP/IP signatures, IPv6 allows for a variety of improvements including greater addressing flexibility, Quality of Service (QoS) provisioning, integrated safety through IPSEC, and enhanced routing competence.
• Making routing tables more hierarchical allows ISPs to decrease the mass of their steering tables.

Key Features of IPv6 

• Configuration by auto 
• Improved multiplex routing 
• Easy management (no more DHCP) 
• There will be no more NAT (Web Address) 
• There will be no private IP conflicts
• The true quality of service (QoS), also known as “flow labeling” 

• Easier headers format 
  • Shorter, better effective routing 
  • Flexibility and upgrades
  • Designed identity and security support 

Difference between IPv4 and IPv6

• Compared with IPv6, IPv4 offers 12 header fields.
• IPv4 uses a numeric addressing system, while IPv6 uses a ten-digit system.
• IPv4 addresses are 32-bits, while IPv6 addresses are 128-bits.
• Checksum fields are part of IPv4 while IPv6 does not.
• The difference between IPv6 and IPv4 is that in IPv4 a dot (.) separates binary bits, whereas in IPv6 a colon (:). 
• In IPv4 and IPv6, the MAC address is determined by ARP (Address Resolution Protocol) and NDP (Neighbor Discovery Protocol).
• Unlike IPv6, IPv4 supports broadcasts.
• The VLSM (Variable Length Subnet Mask) is supported by IPv4 while IPv6 does not.

Why IPv6 for the Networking?

Connect ability

• The benefits of IPv6 include being able to uniquely address network devices without interfering with NAT and firewalls.
• In addition to firewalls and NAT, host devices more advanced and larger have all sorts of tools that make them easier to work in network security projects.

Security

• Encryption is possible with IPv6.
• Through the Secure Neighbour Discovery (SEND) protocol, the cryptographic validation of the identity of a host can be achieved. 
• Name resolution is also more secure with IPv6.
• It is an additional option not universally used, despite it being retrofitted into IPv4. 
• In this way, Address Resolution Protocol (ARP) poison and other naming-based attacks turn into more complicated.

Scalability

• IPv6 provides a unique identifier for IoT commodities over TCP/IP, so if the creators use IPv6 their devices will remain unique for an extensive time.

List of IPv6 simulators

• NS-3.26
• NS-2.35

A description of network simulators for IPv6 protocol is given below. 

NS-3.26 for IPv6 Simulation

• The user applications are implemented in either C++ or Python. 
• Because ns-3 is delivered as sources code, the targeted system must have a program creation platform to construct the utilities first, then the client program.
• The IPv6 system is based on the Linux implement; the class diagram Ipv6 provides a general API, even as the class Ipv6L3 Protocol represents the system’s effective application. 
• This IPv6 stack’s real modules are mostly found in the src/internet section.

The modeling assets in ns-3.26 can also be classified into the following categories: 

• Networking concepts (anything that has the word “routing” in the title)
• Auxiliary classes, such as components, options crossbars, 
• Protocols types (e.g., IPv6, IPv6-l3-protocol, ICMPV6-l4-protocol, etc.) 
• extended headers (e.g., ndisc-cache)
• Things to do with addresses
• Ports and connections (e.g., ipv6-raw-socket, ipv6-interface, ipv6-endpoint, etc.)

IPv6 addresses assignment

• The NS3::Loop backnet device is the net device that is required on any IPv6-enabled ns 3 node. 

Several IPv6 addresses will be assigned to all the other Net Devices:

• The boundary ID is derivative from the Net mechanism MAC address in the fe80::link-local address
• The global address can be zero or more, for example, 2001:db8:: 1.

A link-local address is typically the first one on an interface, followed by the global address (es).

IPv6 global addresses might be:

• Assigned manually 
• Automatically generated

With ns-3, both methods can be performed and it is quite essential to understand both their implications.

NS-2.35 for IPv6 Simulation

• A tool used for studying the dynamic nature of communication networks is Network Simulator Version 2, otherwise known as NS2. 
• It is possible to use NS2 for the simulation of biological and wired networks (e.g., TCP, routing algorithms, UDP).

Proxy Mobile IPv6 Protocol for NS2 Simulator

• In PMIPv6, there are three entities: Mobile node (MN), Local Mobility Anchor (LMA), and. Mobile Access Gateway (MAG)
• PMIPv6 nodes also include encapsulation and encapsulation objects. 
• These appear to have necessitated adjustments to work with the ways the NS node is constructed. 
• To keep our code compliant with the NS2, we would have to change some existent NS2 files. 
• Classes Network is used to represent relevant Node. 
• A very promising localized mobility protocol is proxy mobile IPv6 (PMIPv6), and there have been studies that suggest switching to this protocol is a better choice than using a global mobility protocol (such as MIPv6).
• As part of NS2, PMIPv6 was implemented by adding new agents to the network and by modifying active classifiers. 
• The PMIPv6 interface is applied in the form of a group of NS agents. 
• Agency is the basic class, whereas MN Agent, LMA Agent, and MAG Agent are the related classes.
• PMIPv6 devices are presently processing network solicitations and ads directly. 
• The following graphs demonstrate the PMIPv6 architecture outline and system files.
