This document summarizes research on IPv6 transition mechanisms. It discusses the BD-SIIT (Bi-Directional Stateless IP/ICMP Translation) transition algorithm proposed by the authors. It provides details on BD-SIIT such as the data packet transmission process and comparison with other mechanisms like DSTM. It also outlines performance evaluation metrics like end-to-end delay, throughput and round trip time used to analyze and compare different transition mechanisms. Simulation parameters and references are included.

17. ICIIC2010,Aug-5,6,7. 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.

18. 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= ∑EEDi/Nrec i=1 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 .

19. The mean throughput for a sequence of packets of specific size is calculated by using equations 1 and 2. MeanThr = ∑ N Thrj /N -------------(1) j=1 where Thr=Packets received(Pr)/Packets generated(Pg)*100%.--------------(2) 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 .

20. ICIIC2010,Aug-5,6,7. Simulation Parameters Value 1.Buffer Size 500 Packets 2. Propogation Delay 10ms 3.Payload size 200 Bytes 4.Very traffic Load 6~240 Nodes. 5.Queue Management Scheme Drop tail.
