12. APPLICATIONS OF IPV6 TRANSITION. 1.The IPv6 Transition is mainly used for any cast,Uni cast and Multi cast addresses. 2.The transition of IPv4/IPv6 is also used for the host which acts like a Multi homing. 3.The Transition of IPv4/IPv6 is also used for Sockets .

The development and testing of network services such as DNS, multicast routing, any cast routing, broadcast routing etc. 7.New applications that will stress the network and be used to evaluate the benefits end-users that IPv6 can bring, through the expanded IP addresses, integrated auto-configuration, quality-of-service (QoS), mobility and security

14. 8. The design,implementation and test of both i ntra-domain and inter-domain IPv6 multicast , interoperability with IPv4 multicast will be examined too.

18. (1)Automatic (2)High Performance (3)Without using specific IPv6 address such as 6 to 4 address (4)Peer-to-Peer based IPv4/IPv6 transition method. (5)An economical and Technical IPv4/IPv6 transitional model .

19. (6)During the transition of IPv4/IPv6 period, there will be scenarios where IPv4 and IPv6 applications must coexist and even interoperate . ( 7)The Development of the new IP version is a gradual process which requires the update of network and the applications. Although in future there will be a native IPv6 Scenarios,during the transition period the coexistence between both IPv4 and IPv6 protocols, at the network level and application level is a main issue

20. (8)Research of Ubiquitous and visual IPv4/IPv6 transition technologies and transition model . (9)The gradual transition from IPv4/IPv6 requires network admin to become aware of Next generation protocols and the associated security risks-before deploying IPv6 the administrators must ensure to prevent all unknown IPv6 attacks.

21. (10)The multi-homing transition of IPv4/IPv6 for any cast and multicast addresses . (11)Various Security issues to avoid all the threats in Dual Stacks, Tunneling, Header translation etc . (12)The Transition of IPv4/IPv6 based on sockets . (13)The transition of IPv4/IPv6 based on BDIPS(Bi-Directional intelligent Processing System) that deals with address mapping transition from IPv4 to IPv6 for any cast,multicast,unicast addresses .

30. The BD-SIIT A Novel Transition Address-mapping algorithm for the forward operation Algorithm-1:-IPv4->IPv6: Forward operation 1. When Host X belongs to X-zone initiates a request (Query message) to DNS46 in order to get the IP-address of Host Y which belongs to IPv6 zone. 2. When DNS46 receives a query message as a request then its checks its (Table-2) to identify whether Host Y has an IPv6 address which is unknown for the Host X. The DNS46 knows that the whole IPv6 zone has a public IPv4 address (like NAT method) i.e. 195.18.231.17 address in the destination address field of IPv4 header then forwards it via a network. 3. Simultaneously,the DNS46 sends another message to v4-v6 enabled router in order to update table-3.

31. 4.When the Host X receives requested address of Host Y, immediately creates the IPv4 packet, inserting 195.18.231.17 address in the destination address field of IPv4 header then forwards it via network. 5.When the IPv4 packet is arrived to v4-v6 enabled router, then the router identifies a packet and verifies that a destination address is a public address with mapping value 2 that indeed refers ABC2::4321 IPv6 address(as shown in table-3). Then the V3-V4 enabled router which updates Table-1 then creates its new IPv6 packet which is based on IPv4 packet, and forwards it to its destination in IPv6 Zone.

32. 6. When Host Y accepts the packet then it starts to process it successfully without getting any problem. Algorithm-2: IPv6->IPv4: Feedback operation. Note:-Consider Host X as a Client and Host Y as a Server. If the Client A sent a HTTP get command to retrieve a web page from the server Y.].[As shown in Fig.7.steps 1- 6]. 1.As a response for the received command from a client X, server Y creates packet(s) then forwards them via a network to the client X using the public IPv6 zone address(ABC2::4321) as a destination address. 2.When v4-v6 enabled router receives a packet, which has been sent by Server Y, then it verifies its Table-1,Table-3, depending on the addressing mapping value like 37 in our scenario, it refers to 220.12.145.10 as a Sender address in Table-2 and 223.15.1.3 as a destination address in Table-2 instead of instead of 1C::DACF and ABC2::4321 IPv6 rely.

33. 3.After that, the v4-v6 enabled router creates a new IPv4 packet, based on the accepted IPv6 packet then forward it is to the destination (Client X).When the Client X receives the IPv4 packet,its starts to process successfully without any problem.

34. Implementation and Evaluation . The mean throughput for a sequence of packets of specific size is calculated by using equations 1 and 2 .

36. Conclusions . 1.A comprehensive study has been carried out on diverse transition mechanisms like BD-SIIT and design,performance evaluation using various performance metrics like RTT, EED and Throughput . 2.When we simulated the performance metrics on NS-2 simulator its shows that EED,RTT and Throughput of BD-SIIT are better than other transition mechanisms like DSTM .
