Measurement Target and Procedures Measurement Target

We have classified these mechanism considering the following factors:

1.Architectural Goal

2.Scope

3.Scenarios

Measurement Target and Procedures(a) An IPv6 node connecting to an IPv6 node

through an IPv4 network.

(b) An IPv6 node connecting to an IPv6 node through an IPv4 network supporting NAT.

(c) An IPv4 node connecting to an IPv4 node through an IPv6 network.

(d) An IPv6 node connecting to an IPv4 node.

(e) An IPv4 node connecting to an IPv6 node.

Measurement Target and Procedures

Measurement Target and Procedures Teredo

Teredo is an address assignment and automatic tunneling technology that provides unicast IPv6 connectivity across the IPv4 Internet.

Measurement Target and Procedures ISATAP

Intra-Site Automatic Tunnel Addressing Protocol

Measurement Target and Procedures Testbed Configuration

Measurement Target and Procedures Measurement Procedures

Major measurement subject are CPU utilization, round-trip time, and connect/request/response transaction rate.

Experiments are executed for a period of 60 seconds and data ranging from 64 to 3072 bytes.

Conclusion

Our goal was not to evaluate a specific router or host, but to empirically analyze impacts on transition mechanisms compared with IPv4-only and IPv6-only network performance.

Future work: We intend to investigate mechanisms with security (e.g, IPsec).
