This paper clearly specifies the implementation of BD-SIIT transition algorithm.

The BD-SIIT is a Stateless mapping or Bi-Directional Translation algorithm between IPv4 and IPv6 Packet headers as well as between ICMPv4 and ICMPv6 messages.

This paper proposes the performance analysis of a Novel BD-SIIT Stateless IPv4/IPv6 Translator.

We Implement the BD-SIIT in order to Study their behavior using various evaluation metrics such as Throughput, End-to-End delay(EED), RTT.

The Simulation results of our experiment shows that BD-SIIT RTT,EED, and Throughput performances metrics are better than DSTM when we are using small size IPv6 packet.

IPv4 has 32 bit addresses. Flat addressing (only netid + hostid with “fixed” boundaries) Results in inefficient use of address space. Class B addresses are almost over. Addresses will exhaust in the next 5 years. IPv4 is victim of its own success.


IP does not permit route aggregation (limited super netting possible with new routers)

Mostly only class C addresses remain Number of networks is increasing very fast (number of routes to be

advertised goes up) Very high routing overhead

lot more memory needed for routing table lot more bandwidth to pass routing information lot more processing needed to compute routes


Maximum header length is 60 octets. (Restricts options) Maximum packet length is 64K octets. (Do we need more than that ?) ID for fragments is 16 bits. Repeats every 65537th packet. (Will two packets

in the network have same ID?) Variable size header. (Slower processing at routers.) No ordering of options. (All routers need to look at all options.)


Lack of quality-of-service support. Only an 8-bit ToS field, which is hardly used. Problem for multimedia services.

No support for security at IP layer. Mobility support is limited.


IPv6 quadruples the size of an IPv4 address from 32 bits to 128 bits. The IPv6 address is so large that it cannot be exhausted in the foreseeable future.

IPv6 addressing: An IPv6 address consists of 16 bytes. It is 128 bits long. 28 bits are divided into 8 sections, size of each section is 2 bytes. Each section IPv6 is represented by 4 Hexadecimal digits. Therefore, it is totally represented by 32 Hexadecimal digits with every four digits separated by a colon.

No “flag” day. Incremental upgrade and deployment. Minimum upgrade dependencies. Interoperability of IPv4 and IPv6 nodes. Let sites transition at their own pace. Basic migration tools

Dual stack and tunneling Translation


New nodes support both IPv4 and IPv6. Upgrading from IPv4 to v4/v6 does not break anything. Same transport layer and application above both. Provides complete interoperability with IPv4 nodes.



Figure-2:Dual Stack

Tunnel IPv6 packets across IPv4 topology. Configured tunnels:

Explicitly configured tunnel endpoints. Router to router,host to router.

Automatic tunnels: Automatic address resolution using embedded IPv4 address (like IPv4-

compatible address). Host to host, router to host



Figure-3: Automatic Tunneling Figure-4: Configured Tunneling

This will allow communication between IPv6 only hosts and IPv4 only hosts. A typical translator consists of two components:

translation between IPv4 and IPv6 packets. Address mapping between IPv4 and IPv6

For translation, three technologies are available: header conversion transport relay application proxy



Figure-5: Header Translation

V4-V6 DNS(DNS46) server determines two public IPv4 and IPv6 addresses which are statistically or dynamically exist for IPv4/IPv6 communication system.

V4-V6 Enabled Gateway which performs address mapping between IPv4 and IPv6 addresses as well as IPv4 and IPv6 header conversion.



Figure-6: BD-SIIT Translation Process


Figure-7: Translation of IPv6 to IPv4 Header

To reduce the packet size compared with Tunneling Algorithms, in turn, reducing traffic overhead.

Reduce the cost of IPv6 Network by avoiding the need to upgrade all the edge nodes that support both the IPv4 and IPv6 as found in Dual Stack mechanisms.

Use a new address mapping that depends on identifying two Public addresses (IPv4 and IPv6) instead of IPv4 mapped IPv6 address method.

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.


Figure-9: BD-SIIT Network model

In this Paper we have calculated three performance evaluation metrics.

1.End to End delay

2.Throughput

3.Round trip time (RTT)

1.Mean End to End delay= i=1∑Nrec 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.


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

MeanThr = ΣN 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.


Simulation Parameters

Value

1.Buffer Size 500 Packets

2. Propagation Delay 10ms

3.payload size 200 Bytes

4.Very traffic Load 6~240 Nodes.

5.Queue Management Scheme Drop tail.

This paper has proposed our Novel BD-SIIT transition mechanism.

The Novel transition concentrated on identifying,determining,translating, and forwarding packets between the two different network environments IPv6 and IPv4 network zones.

Our proposed BD-SIIT reduces the size of a Packet compared with the encapsulation method in the tunneling algorithm.
