ABSTRACT

Our Project focues on achieving IPv6 mobility convergence and deployment. We will develop the IPv6 mobility procotols such as Mobile IP [1], NEMO [2] and MANET [3], and the infrastructure converging the several mobility protocols.

We bring our NEMO basic support [4] implementation to Connectathon 2004 [5] (interoperability testing).

Connectathon Basics

Connectathon testing event was held Feb 23-28 2004 in San Jose, California
Various protocols such as NFS, Mobile IPv4/v6, and this year, NEMO, are tested
The goal of the event is to test concept implementations, and improve the correctness and interoperability of new & old implementations, through Interop tests and Conformance tests

Participants

Tree NEMO Basic Support implementations including us
Keio, Nautilus, Nokia

Testing Setup

A test network was constructed with 3 HAs, 2 MRs and 2 MNNs
Topology for NEMO

Testing Outline

DHAAD - modified to only return list of HAs supporting Mobile Routers
MR home registration with Prefix Option, Both MRs registered with one HA, Each MR registered with a different HA
Ping was sent from MNN1 to MNN2, passing through both MRs and both HAs -for both cases above
Explicit Mode was tested (Implicit is supported by at least some implementations, but was not tested)
All tests ended in success

IPSec

MR home registration with Prefix Option was also tested with IPsec
IPsec was tested between HA and MR for both pairs -- Ours and one of others
IPsec implementations interoperated successfully between each other��s HA/MR
Method used: ESP (DES-CBC) with authentication (HMAC-MD5)

Conclusions

All tests were successful! Including IPsec interoperability. This exercise provided valuable experience and validates the NEMO Basic Support concept and implementability. NEMO was a good aliition to the Connectathon suite of tests this year.
