Alternative 4 Initially X is located at A1 then it moves to A2. γ Z C MSR-α Mα X A1 α γ Z C MSR-α Mα α R ⇒ R δ MSR-β Mβ β δ MSR-β Mβ X A2 β Figure 13. X sends a message to MSR-β, to get it’s new address A2 and says it’s old MSR was MSR-α. ✘ MSR-α must now perform host specific routing to MSR-β (which can provide the local address A2) ✔ Z is now completely unaware of the move - it always sends traffic to MSR-α. ✔ If X moves again, Z does not change where it sends traffic to & traffic need not go via MSR-β - it will go directly from MSR-α to the MSR responsible for the new segment.

Alternative 4 continued Initially X is located at A1 then it moves to A2 and then moves to A3. γ Z C MSR-α Mα X A1 α γ Z C MSR-α Mα α R ⇒ R δ MSR-β Mβ β δ R MSR-ε Mε X A3 ε Figure 14. X sends a message to MSR-ε, to get it’s new address A3 and says it’s old MSR was MSR-α. ✔ The traffic from MSR-α to MSR-β or MSR-α to MSR-ε can be encapsulated, using for example IP in IP (written IP-IP) encapsulation. Thus none of the intervening routers needs know about mobility. Maguire Objectives of Mobile IP 11: 19 of 50 maguire@kth.se 2010.03.21 Internetworking/Internetteknik
