Network Mobility support ? Demand for Internet access in mobile platforms (e.g. trains, buses) is increasing ? There are some proposals for supporting Network Mobility ? One of them is done within the IETF NEMO WG ? NEMO Basic Support Protocol ? Mobility managed at IP level ? Based on Mobile IPv6 protocol (i.e. terminal mobility) ? Bidirectional tunnel between MR and HA 2004-08-11 MIRON [ 4 / 15 ]

Route Optimization issue ? NEMO Basic Support Protocol has one of the problems of Mobile IPv6: ? Triangle Routing ? Solved in Mobile IPv6 with the Route Optimization support ? MIRON adapts MIPv6 RO to optimize CN-LFN flows ? Besides, NEMOs can be NESTED ? Pinball Routing ? Some solutions proposed so far ? No one seems to solve the problem properly ? MIRON proposes an address delegation mechanism with built-in routing that avoids the tunnel overhead 2004-08-11 MIRON [ 7 / 15 ]
MIRON. Single Mobile Network (I) ? Goals and requirements ? To provide Transparent Route Optimization between a LFN and a CN ? Avoiding triangle routing ? Preserving CN and LFN operation unchanged ? Basically consists in performing MIPv6 Route Optimization procedure between the MR (on behalf of the LFN) and the CN ? The solution profits from the installed base of CNs that support MIPv6 RO 2004-08-11 MIRON [ 8 / 15 ]

MIRON. Nested Mobile Networks (I) ? Goals and requirements ? To provide Transparent Route Optimization for Nested Mobile Networks ? Avoiding pinball routing ? Preserving CNs and MNNs operation unchanged ? Basically consists in delegating topologically correct IPv6 addresses to every MR within a nested NEMO ? Routing of packets within the NEMO is also provided 2004-08-11 MIRON [ 11 / 15 ]

MIRON. Conclusions and future work ? MIRON provides Route Optimization for NEMO ? LFN-CN RO ? Route Optimization between LFN and CN (MR performs MIPv6 RO on behalf of the LFN) ? Avoid triangle routing ? Requires flow identification and tracking ? Nesting RO ? Provides valid and reachable IPv6 addresses to every MR within the nested, to be used as CoAs ? Avoid pinball routing ? Can be used also separately to avoid tunnels introduced by nesting (or together with the previous) ? Use of prefix delegation should also be studied 2004-08-11 MIRON [ 14 / 15 ]
