22. 1. IPv4-mapped address (0: FFFF: v4):-This is an IPv6 address simply created by including the IPv4 address of the IPv4 host (v4) with the prefix shown. The BD-SIIT mainly uses this type of address for the conversion of IPv4 host addresses to IPv6 addresses. 2.IPv4 translated addresses (0::FFFF:v4):- According to IETF specifications this address is created by IPv4 address temporarily assigned to the IPv6-only host and allows for the mapping of the IPv4-translated address of the IPv6 host to an IPv4 address. As the number of globally unique IPv4 addresses becomes scarce, there is a need to take advantage of IP Header Translation. July 23-27 ICEMC2-2010,Kuppam,AP,INDIA.

26. Comparison and Contrast between BD-SIIT and DSTM Transition Mechanism. BD-SIIT DSTM 1.It does not for tunneling technique . 1. A tunneling technique needs to be configured. 2. Two IPv4 and IPv6 addresses are assumed to be globally unique. 2.Only IPv4 addresses are assumed to be globally unique . 3.It Uses two types of global IP addresses that are assigned by DNS46 server for each communication system. 3. Uses only a pool of IPv4 addresses in order to assign Global IPv4 address for each communication system. 4.Applicable for Bi-Directional commn between IPv6 only nodes and IPv4 nodes. 4.Not applicable to IPv6 only nodes that want to communicate with IPv4 only node. 5.Less cost 5.High Cost 6.Does not require upgrading or extra software to be used at end user nodes. 6.Requires modifications or extra software to support the dual stack on the end user nodes. 7.Transition from IPv4 to IPv6 and Vice versa is needed. 7.Encapsulation and Decapsulation methods are needed.
27. Comparison and Performance evaluation metrics of a Novel IPv4/IPv6 Transition Mechs :BD-SIIT and DSTM. Fig.5.BD-SIIT Network model .
29. In this Paper we have calculated three performance evaluation metrics . 1.End to End delay 2.Throughput 3.Round trip time(RTT) N rec 1.Mean End to End delay= ∑ i=1 EEDi/Nrec where EEDi = Tdi- Tsi where EEDi is the end to end delay of ith packet. Tsi is the Source packet i created and Tdi is the Destination packet which is created at Destination. Nrec is the total number of packets received at Dest host and Mean EED is the mean value of each communication session. Performance evaluation metrics and Simulation Parameters.
30. The mean throughput for a sequence of packets of specific size is calculated by using equations 1 and 2. MeanThr = Σ N j =1 Thrj /N -------------(1) where Thr=Packetsreceived(Pr)/Packets generated(Pg)*100%.--------------(2) Where Thrj is the value of the throughput when the packet j is received at intermediate device like DSTM gateway,BD-SIIT Gateway,v4/v6 Router and N is the number of received packets at intermediate device,Pr is the no of packets received at intermediate device and Pg is the number of packets created by source host .
