Proposal Mobility Label MP-BGP and MPLS-based mobility management solution resulting in optimal traffic delivery (no triangular routing) Evolutionary architecture based on the existing widely used protocol framework (MPLS and MP-BGP) Support for mobile host (mobile-to-fixed, mobile-to-mobile) and mobile router communications Support for IPv4 and IPv6 Increased scalability due to built-in control plane capabilities Main Ideas Independence from Mobile IP – no need for HA, CoA, FA and L3 tunneling Mobility Support Function (MSF) on the Label Edge Router (LER) Mobile Host/Router Discovery, Registration and Status Mobility Label Association/De-association, Mobility Bindings Integration with MP-BGP and Network Update Procedures Mobile Application Priority Indication and Recognition Similar to label advertisement mechanism in RFC 4364 for L3 VPNs Introduce new element (Mobility Address Family) into MP-BGP to carry Mobility Bindings Introduce Mobility Labels and Mobility Bindings to: De-couple IP layer topology from the user location in the network Associate the new user location with the fixed L3 protocol address Use stacked MPLS labels for the identification of IP addresses and efficient traffic delivery Indicate mobile application parameters to the network |
